As first described in the 1980s, the core food intake model allows a precise assessment of dietary nutrient intake and dietary exposure to contaminants insofar as it reflects the eating habits of a target population and covers the most important foods in terms of consumption, selected nutrient and contaminant contribution. This model has been used to set up the sampling strategy of the second French Total Diet Study (TDS) with the aim of obtaining a realistic panorama of nutrient intakes and contaminant exposure for the whole population, useful for quantitative risk assessment. Data on consumption trends and eating habits from the second French individual food consumption survey (INCA2) as well as data from a 2004 purchase panel of French households (SECODIP) were used to identify the core foods to be sampled. A total of 116 core foods on a national scale and 70 core foods on a regional scale were selected according to (1) the consumption data for adults and children, (2) their consumer rates, and (3) their high contribution to exposure to one or more contaminants of interest. Foods were collected in eight French regions (36 cities) and prepared 'as consumed' to be analysed for their nutritional composition and contamination levels. A total of 20 280 different food products were purchased to make up the 1352 composite samples of core foods to be analysed for additives, environmental contaminants, pesticide residues, trace elements and minerals, mycotoxins and acrylamide. The establishment of such a sampling plan is essential for effective, high-quality monitoring of dietary exposure from a public health point of view.

Reducing food losses and waste is considered to be one of the most promising measures to improve food security in the coming decades. Food losses also affect our use of resources, such as freshwater, cropland, and fertilisers. In this paper we estimate the global food supply losses due to lost and wasted food crops, and the resources used to produce them. We also quantify the potential food supply and resource savings that could be made by reducing food losses and waste. We used publically available global databases to conduct the study at the country level. We found that around one quarter of the produced food supply (614 kcal/cap/day) is lost within the food supply chain (FSC). The production of these lost and wasted food crops accounts for 24% of total freshwater resources used in food crop production (27 m(3)/cap/yr), 23% of total global cropland area (31 × 10(-3)ha/cap/yr), and 23% of total global fertiliser use (4.3 kg/cap/yr). The per capita use of resources for food losses is largest in North Africa & West-Central Asia (freshwater and cropland) and North America & Oceania (fertilisers). The smallest per capita use of resources for food losses is found in Sub-Saharan Africa (freshwater and fertilisers) and in Industrialised Asia (cropland). Relative to total food production, the smallest food supply and resource losses occur in South & Southeast Asia. If the lowest loss and waste percentages achieved in any region in each step of the FSC could be reached globally, food supply losses could be halved. By doing this, there would be enough food for approximately one billion extra people. Reducing the food losses and waste would thus be an important step towards increased food security, and would also increase the efficiency of resource use in food production.

Quantifying food waste in Hawaii's food supply chain.

Food waste highlights a considerable loss of resources invested in the food supply chain. While it receives a lot of attention in the global context, the assessment of food waste is deficient at the sub-national level, owing primarily to an absence of quality data. This article serves to explore that gap and aims to quantify the edible weight, economic value, and calorie equivalent of food waste in Hawaii. The estimates are based on available food supply data for Hawaii and the US Department of Agriculture's (USDA's) loss-adjusted food availability data for defined food groups at three stages of the food supply chain. At its highest aggregated level, we estimate Hawaii's food waste generation at 237,122 t or 26% of available food supply in 2010. This is equivalent to food waste of 161.5 kg per person, per annum. Additionally, this food waste is valued at US$1.025 billion annually or the equivalent of 502.6 billion calories. It is further evident that the occurrence of food waste by all three measures is highest at the consumer stage, followed by the distribution and retail stage, and is lowest at the post-harvest and packing stage. The findings suggest that any meaningful intervention to reduce food waste in Hawaii should target the consumer, and distribution and retail stages of the food supply chain. Interventions at the consumer stage should focus on the two protein groups, as well as fresh fruits and fresh vegetables. © The Author(s) 2015.
Developing sustainable food supply chains.

Smith, B Gail

2008-02-27

This paper reviews the opportunities available for food businesses to encourage consumers to eat healthier and more nutritious diets, to invest in more sustainable manufacturing and distribution systems and to develop procurement systems based on more sustainable forms of agriculture. The important factors in developing more sustainable supply chains are identified as the type of supply chain involved and the individual business attitude to extending responsibility for product quality into social and environmental performance within their own supply chains. Interpersonal trust and working to standards are both important to build more sustainable local and many conserved food supply chains, but inadequate to transform mainstream agriculture and raw material supplies to the manufactured and commodity food markets. Cooperation among food manufacturers, retailers, NGOs, governmental and farmers' organizations is vital in order to raise standards for some supply chains and to enable farmers to adopt more sustainable agricultural practices.
Developing Exchange in Short Local Foods Supply Chains

Directory of Open Access Journals (Sweden)

Per Engelseth

2016-07-01

Full Text Available The supply chain management of foods is commonly associated with modernistic large-scale production. This involves long transport distances of foods to reach consumers. In the case of local foods, supply chains are shorter. Based on a case study of five local foods producer's supply of their products to a common retailer, the supply chain of local foods is modelled conceptually and modes of development are pointed out based on contingency theory and supply chain management literature. Findings reveal that since these chains are transparent, reciprocal interdependency is abundant mainly because human perception creates a sufficient understanding of the operations management issues pertinent within this simple inter-organisational structure. Local foods supply chains are similar to service supply chains. This includes that both are short in nature and associated with bi-directional interaction between the customer and supplier. Developing short supply chains in local foods supply is associated with improving the exchange economy found in short supply chains. This also implies that development of local foods supply is associated with two paths which may be complementary. First, the use of improved intensive technology associated with reciprocal interdependency to develop efficiencies in the bi-directional and somewhat complex interaction. Alternatively local foods suppliers may seek to reduce this form of reciprocal interdependency thereby increasing the impact of pooled interdependencies and enabling using mediating technology involving standardising interaction such as through increased standardised products and packaging as well as automation of information connectivity.
The impact of food regulation on the food supply chain.

Aruoma, Okezie I

2006-04-03

Food regulation in the main is aimed at protecting the consumer's health, increasing economic viability, harmonizing well-being and engendering fair trade on foods within and between nations. Consumers nowadays are faced with food or food ingredients that may derive from distant countries or continents, and with a less transparent food supply. Safety concerns must cover the range of different food chains relevant to a certain food product or product group, including all relevant producers, manufacturing sites and food service establishments within a country as well as those importing into the country. Hazard analysis at critical control points (HACCP), good manufacturing practice (GMP) and good hygiene practice (GHP) are major components of the safety management systems in the food supply chain. Principally, "a hazard" is a biological, chemical or physical agent in, or condition of, food that has the potential to cause an adverse health effect. The likelihood of occurrence and severity of the same is important for the assessment of the risk presented by the hazard to the food supply chain. The Government's regulatory mechanisms in accordance with the WTO agreements (HACCPs, sanitary and phytosanitary measures, etc.) oversee the analyses of public health problems and their association to the food supply. Under the WTO SPS Agreements and the codes of practices issued by the Codex Alimentarius Commission, there now exists a benchmark for international harmonization that guarantee the trade of safe food. Inevitably, food safety is still mainly the responsibility of the consumer.

The food loss rate is a factor that represents food consumption efficiency. To improve food consumption efficiency, we need to fundamentally quantify food loss at national and global levels. This study examines food and food waste flow and calculates the food loss rate in the food supply chain by targeting Japan. We analyzed inedible food waste and avoidable food losses in wholesale, manufacturing, retail, food services, and households and considered different supply chain pathways, different food categories representing whole Japanese meals, and weight changes after cooking. The results are as follows: (1) Japan has an overall rate of avoidable food losses of approximately 15% for meals (excluding agricultural losses), (2) the supply sector with the highest food loss rate is food services, and (3) the food category with the highest food loss rate is vegetables. Finally, we proposed a model for calculating food loss rates that could be used for future analysis in Japan or other countries. Copyright © 2017 Elsevier Ltd. All rights reserved.
Population Model with a Dynamic Food Supply

Science.gov (United States)

Dickman, Ronald; da Silva Nascimento, Jonas

2009-09-01

We propose a simple population model including the food supply as a dynamic variable. In the model, survival of an organism depends on a certain minimum rate of food consumption; a higher rate of consumption is required for reproduction. We investigate the stationary behavior under steady food input, and the transient behavior of growth and decay when food is present initially but is not replenished. Under a periodic food supply, the system exhibits period-doubling bifurcations and chaos in certain ranges of the reproduction rate. Bifurcations and chaos are favored by a slow reproduction rate and a long period of food-supply oscillation.
Cutting Food Waste through Cooperation along the Food Supply Chain

2015-01-01

Full Text Available Food produced but not used for human consumption is a waste of natural resources. In order to prevent and reduce food waste, the main causes have to be identified systematically along the food supply chain (FSC. The aim of this study is (1 to shed light on the causes and effects of food waste through the analysis of 44 qualitative expert interviews examining the processes and intermediaries along the German food chain and (2 to find methods to reduce it. Results indicate that food waste occurs at all stages in the food chain. Thus, there is no single culprit to be blamed. Besides, the identified reasons for food waste differ between product groups; not a single solution can cause notable change. Furthermore, the analysis demonstrates that the causes and effects of food waste are to be found at different stages of the value chain. Hence, it is of high importance to improve communication and to raise a new appreciation for food among all stakeholders of the food supply chain in order to develop a more sustainable food system. Information on the topic of food waste needs to be shared among all actors of the supply chain. They need to share responsibility and work together to reduce food waste.

The 2008-2010 food crisis might have been a harbinger of fundamental climate-induced food crises with geopolitical implications. Heat-wave-induced yield losses in Russia and resulting export restrictions led to increases in market prices for wheat across the Middle East, likely contributing to the Arab Spring. With ongoing climate change, temperatures and temperature variability will rise, leading to higher uncertainty in yields for major nutritional crops. Here we investigate which countries are most vulnerable to teleconnected supply-shocks, i.e. where diets strongly rely on the import of wheat, maize, or rice, and where a large share of the population is living in poverty. We find that the Middle East is most sensitive to teleconnected supply shocks in wheat, Central America to supply shocks in maize, and Western Africa to supply shocks in rice. Weighing with poverty levels, Sub-Saharan Africa is most affected. Altogether, a simultaneous 10% reduction in exports of wheat, rice, and maize would reduce caloric intake of 55 million people living in poverty by about 5%. Export bans in major producing regions would put up to 200 million people below the poverty line at risk, 90% of which live in Sub-Saharan Africa. Our results suggest that a region-specific combination of national increases in agricultural productivity and diversification of trade partners and diets can effectively decrease future food security risks.

Non-supermarket food retailers can be a promising channel for increasing the availability of healthy foods in underserved communities. The present paper reports on retailer practices, attitudes and beliefs about the supply of healthy foods before and after the introduction of new subsidies for healthy foods by the US Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in October 2009. We designed and conducted in-person standardized interviews with store owners and managers to assess perceptions of demand and profits for different foods, supply networks, barriers to stocking healthy foods and their changes following implementation of the new WIC packages. Non-supermarket retailers in five towns of Connecticut, USA (n 68 in 2009 and n 58 in 2010). Owners and managers of WIC-authorized and non-WIC convenience stores and non-chain grocery stores. Retailers identified customer demand as the primary factor in stocking decisions. They reported observing a significantly weaker demand for healthy foods compared with unhealthy foods, although it improved for certain foods with the new WIC subsidies. Less healthy foods were also perceived as more profitable. Supplier networks varied by product from convenient manufacturer delivery for salty snacks to self-supply for produce. WIC retailers were able to quickly adapt and supply healthy foods required under the new WIC programme guidelines. Retailers other than supermarkets currently perceive little demand for healthy foods, but new WIC subsidies have the power to change these perceptions. Supply barriers seem secondary in the limited offerings of healthy foods by stores and could be overcome when policy changes generate new demand for healthy foods.

Full Text Available Information sharing serves as an essential approach for the companies and antecedents of supply chain integration. Nowadays, with the highly competitive in halal food market, information sharing has become more conceivable. Furthermore, information sharing in supply chains has become more efficient by having meaningful relationship with the members of halal supply chain. There is a lack information regarding information shared within members in halal food supply chain literature. The information needed in order to shed the light of how companies nowadays can be more competitive. The purpose of this study is to investigate to what extent the information can be shared among the members of the halal food supply chain. This study elaborates the barriers of information sharing leading to enhanced supply chain integration among enterprises, as a result. The interview with four managers from halal certified food manufactures has been deployed to get rich data about the information sharing. The finding shows that most of cases halal certified food manufacturers has low communication with their suppliers. Trust is the key enablers within the members of halal food supply chain.

U.S. healthcare costs consistently outpace inflation, causing growing problems of affordability. This trend cannot be sustained indefinitely. The purpose of this study is to use supply-chain tools for macro-level examination of the U.S. healthcare as a business system and identify options and best use practices. We compare the important and successful U.S. food industry to the essential but problematic U.S. healthcare industry. Supply chain strategies leading to food business operations success are examined and healthcare applications suggested. We emphasize "total cost of ownership" which includes all costs incurred by all stakeholders of U.S. healthcare, including maintenance and cleanup, not just the initial purchase price. U.S. hospitals and clinics can use supply chain strategies in a total cost of ownership framework to reduce healthcare costs while maintaining patient care quality. Supply chain strategies of resource pooling, mass customization, centralized logistics, specialization, postponement and continuous improvement that have been successfully used in the U.S. food industry should be more widely applied to the U.S. healthcare industry. New and growing areas of telemedicine and medical tourism should be included in the supply chain analysis of U.S. healthcare. Valid statistical analysis of results in all areas of U.S. healthcare is an important part of the process. U.S. healthcare industry problems are systematic operational and supply chain problems rather than problems with workforce or technology. Examination of the U.S. healthcare industry through a supply chain framework should lead to significant operational improvement in both prevention and treatment of acute and chronic ailments. A rational and unemotional reorganization of the U.S. healthcare system operations, using supply chain strategies, should help reduce healthcare costs while maintaining quality and increasing accessibility.

In the future, new technologies and practices based on energy from renewable resources are central for the development of our food supply system and they will contribute in two different ways....... As the energy sector increasingly bases energy supply on renewable sources, the energy requirements of the food sector will automatically substitute renewable energy for non-renewable energy in all stages of food supply. In principle, the food sector does not need to change if renewable energy is sufficient...... and available as the energy carriers that we are used to today. We may think of this as passive adaptation. A passive adaptation strategy may support a development towards the image ‘high input – high output’.

Full Text Available The production and number of processed food industries have slightly increased; as a result, the companies must compete to maximize their profits by conducting their efficient production process. CV. Fiva Food is one of the companies in the field of processed foods, especially in processed meat that has implemented supply chain management. It is necessary for the company to take measurements of its performance and efficiency for the entire supply chain such as procurement of raw materials. The purposes of this study were to analyze the performance of the company's supply chain and determine the most efficient method of procurement for its raw materials as well as and to provide recommendations for the company to improve its performance of entire supply chain. This study used SCOR in analyzing the performance of supply chain and EOQ and POQ method to be compared with the method that the company uses to determine which method of procurement for raw materials is the most efficient one. The result showed that based on the matrix, the company's performance is unfavorable when it was compared to the benchmark performance of inventory days of supply. In addition, this study showed that the POQ method produces the lowest total inventory cost with savings of Rp6.647.015 for raw materials of MDM whereas EOQ method produced the lowest total inventory cost with savings of Rp222.153,78 for raw materials of FQ85CL.

Few studies have focused on the relationship between the retail food environment and household food supplies. This study examines spatial access to retail food stores, food shopping habits, and nutrients available in household food supplies among 50 Mexican-origin families residing in Texas border colonias. The design was cross-sectional; data were collected in the home March to June 2010 by promotora-researchers. Ground-truthed methods enumerated traditional (supercenters, supermarkets, grocery stores), convenience (convenience stores and food marts), and non-traditional (dollar stores, discount stores) retail food stores. Spatial access was computed using the network distance from each participant's residence to each food store. Data included survey data and two household food inventories (HFI) of the presence and amount of food items in the home. The Spanish language interviewer-administered survey included demographics, transportation access, food purchasing, food and nutrition assistance program participation, and the 18-item Core Food Security Module. Nutrition Data Systems for Research (NDS-R) was used to calculate HFI nutrients. Adult equivalent adjustment constants (AE), based on age and gender calorie needs, were calculated based on the age- and gender composition of each household and used to adjust HFI nutrients for household composition. Data were analyzed using bivariate analysis and linear regression models to determine the association of independent variables with the availability of each AE-adjusted nutrient. Regression models showed that households in which the child independently purchased food from a convenience store at least once a week had foods and beverages with increased amounts of total energy, total fat, and saturated fat. A greater distance to the nearest convenience store was associated with reduced amounts of total energy, vitamin D, total sugar, added sugar, total fat, and saturated fat.

Oil price, biofuels and food supply

Timilsina, Govinda R.; Mevel, Simon; Shrestha, Ashish

2011-01-01

The price of oil could play a significant role in influencing the expansion of biofuels, but this issue has yet to be fully investigated in the literature. Using a global computable general equilibrium (CGE) model, this study analyzes the impact of oil price on biofuel expansion, and subsequently, on food supply. The study shows that a 65% increase in oil price in 2020 from the 2009 level would increase the global biofuel penetration to 5.4% in 2020 from 2.4% in 2009. If oil prices rise 150% from their 2009 levels by 2020, the resulting penetration of biofuels would be 9%, which is higher than that would be caused by current mandates and targets introduced in more than forty countries around the world. The study also shows that aggregate agricultural output drops due to an oil price increase, but the drop is small in major biofuel producing countries as the expansion of biofuels would partially offset the negative impacts of the oil price increase on agricultural outputs. An increase in oil price would reduce global food supply through direct impacts as well as through the diversion of food commodities and cropland towards the production of biofuels. - Highlights: ► A global CGE model to analyze impacts of oil price on biofuels and food supply. ► Global biofuel penetration increases from 2.4% (2009) to 5.4% (2020) in baseline. ► A 150% rise of oil price boosts biofuels more than current mandates and targets do. ► Biofuels partially offset drops in agricultural outputs caused by oil price rise. ► Biofuels as well as oil price rise negatively affect global food supply.

Agri-food is very important for human being. Problems in managing agri-food are very complicated. There are many entities involved in managing agri-food with conflict of interest between them makes the problems become more complicated. Using supply chain approaches in agri-food will help solving the problems. The purpose of this paper is to show that the publications in agri-food supply chain research area are still promising and to show the research trend in agri-food supply chain. The study was a bibliometric study by using some queries on the website with the largest database of peer-reviewed literature. The queries were using various categories and refinements. Firstly the study was exploring all publications in this research area in some categories and then divided the duration into 2 intervals. The last query was to know how many publications are review type publications. The results show that the number of the publications with agri-food supply chain topics are still limited, and tend to increase. It means researches in this area are still promising. The results also show the most publications are from which source title, country, and affiliation. The results also show the research trend in this research area. The quantities of review type publications in agri-food supply chain are still few. It shows the need for more review type publications in this area.

In this paper, based on the imbalance of the supply-demand relationship of food, we design a spreading model of food safety risk, which is about from food producers to consumers in the food supply chain. We use theoretical analysis and numerical simulation to describe the supply-demand relationship and government supervision behaviors' influence on the risk spread of food safety and the behaviors of the food producers and the food retailers. We also analyze the influence of the awareness of consumer rights protection and the level of legal protection of consumer rights on the risk spread of food safety. This model contributes to the explicit investigation of the influence relationship among supply-demand factors, the regulation behavioral choice of government, the behavioral choice of food supply chain members and food safety risk spread. And this paper provides a new viewpoint for considering food safety risk spread in the food supply chain, which has a great reference for food safety management.

Water resources, essential to sustain human life, livelihoods and ecosystems, are under increasing pressure from population growth, socio-economic development and global climate change. As the largest freshwater resource on Earth, groundwater is key for human development and food security. Yet, excessive abstraction of groundwater for irrigation, driven by an increasing demand for food in recent decades, is leading to fast exhaustion of groundwater reserves in major agricultural areas of the world. Some of the highest depletion rates are observed in Pakistan, India, California Central Valley and the North China Plain aquifers. In addition, the growing economy and population of several countries, such as India and China, makes prospects of future available water and food worrisome. In this context, it is becoming particularly challenging to sustainably feed the world population, without exhausting our water resources. Besides, food production and consumption across the globe have become increasingly interconnected, with many areas' agricultural production destined to remote consumers. In this globalisation era, trade is crucial to the world's food system. As a transfer of water-intensive goods, across regions with varying levels of water productivity, food trade can save significant volumes of water resources globally. This situation makes it essential to address the issue of groundwater overuse for global food supply, accounting for international food trade. To do so, we quantify the current, global use of non-renewable groundwater for major crops, accounting for various water productivity and trade flows. This will highlight areas requiring quickest attention, exposing major exporters and importers of non-renewable groundwater, and thus help explore solutions to improve the sustainability of global food supply.

Highlights: • We propose a chaotic food chain model supplying additional food to top-predator. • Local and global stability conditions are derived in presence of additional food. • Chaos is controlled only by increasing quantity of additional food. • System enters into periodic region and depicts Hopf bifurcations supplying additional food. • This an application of non-chemical methods for controlling chaos. -- Abstract: The control and management of chaotic population is one of the main objectives for constructing mathematical model in ecology today. In this paper, we apply a technique of controlling chaotic predator–prey population dynamics by supplying additional food to top-predator. We formulate a three species predator–prey model supplying additional food to top-predator. Existence conditions and local stability criteria of equilibrium points are determined analytically. Persistence conditions for the system are derived. Global stability conditions of interior equilibrium point is calculated. Theoretical results are verified through numerical simulations. Phase diagram is presented for various quality and quantity of additional food. One parameter bifurcation analysis is done with respect to quality and quantity of additional food separately keeping one of them fixed. Using MATCONT package, we derive the bifurcation scenarios when both the parameters quality and quantity of additional food vary together. We predict the existence of Hopf point (H), limit point (LP) and branch point (BP) in the model for suitable supply of additional food. We have computed the regions of different dynamical behaviour in the quantity–quality parametric plane. From our study we conclude that chaotic population dynamics of predator prey system can be controlled to obtain regular population dynamics only by supplying additional food to top predator. This study is aimed to introduce a new non-chemical chaos control mechanism in a predator–prey system with the
Research on the Food Security Condition and Food Supply Capacity of Egypt

2014-01-01

Full Text Available Food security is chronically guaranteed in Egypt because of the food subsidy policy of the country. However, the increasing Egyptian population is straining the food supply. To study changes in Egyptian food security and future food supply capacity, we analysed the historical grain production, yield per unit, grain-cultivated area, and per capita grain possession of Egypt. The GM (1,1 model of the grey system was used to predict the future population. Thereafter, the result was combined with scenario analysis to forecast the grain possession and population carrying capacity of Egypt under different scenarios. Results show that the increasing population and limitations in cultivated land will strain Egyptian food security. Only in high cultivated areas and high grain yield scenarios before 2020, or in high cultivated areas and mid grain yield scenarios before 2015, can food supply be basically satisfied (assurance rate ≥ 80% under a standard of 400 kg per capita. Population carrying capacity in 2030 is between 51.45 and 89.35 million. Thus, we propose the use of advanced technologies in agriculture and the adjustment of plant structure and cropping systems to improve land utilization efficiency. Furthermore, urbanization and other uses of cultivated land should be strictly controlled to ensure the planting of grains.

Increasing Capacity Exploitation in Food Supply Chains Using Grid Concepts

Science.gov (United States)

Volk, Eugen; Müller, Marcus; Jacob, Ansger; Racz, Peter; Waldburger, Martin

Food supply chains today are characterized by fixed trade relations with long term contracts established between heterogeneous supply chain companies. Production and logistics capacities of these companies are often utilized in an economically inefficient manner only. In addition, increased consumer awareness in food safety issues renders supply chain management even more challenging, since integrated tracking and tracing along the whole food supply chain is needed. Facing these issues of supply chain management complexity and completely documented product quality, this paper proposes a full lifecycle solution for dynamic capacity markets based on concepts used in the field of Grid [1], like management of Virtual Organization (VO) combined with Service Level Agreement (SLA). The solution enables the cost-efficient utilization of real world capacities (e.g., production capacities or logistics facilities) by using a simple, browser-based portal. Users are able to enter into product-specific negotiations with buyers and suppliers of a food supply chain, and to obtain real-time access to product information including SLA evaluation reports. Thus, business opportunities in wider market access, process innovation, and trustworthy food products are offered for participating supply chain companies.

Hawkes, Corinna

2009-01-01

The mapping and analysis of supply chains is a technique increasingly used to address problems in the food system. Yet such supply chain management has not yet been applied as a means of encouraging healthier diets. Moreover, most policies recommended to promote healthy eating focus on the consumer end of the chain. This article proposes a consumption-oriented food supply chain analysis to identify the changes needed in the food supply chain to create a healthier food environment, measured in terms of food availability, prices, and marketing. Along with established forms of supply chain analysis, the method is informed by a historical overview of how food supply chains have changed over time. The method posits that the actors and actions in the chain are affected by organizational, financial, technological, and policy incentives and disincentives, which can in turn be levered for change. It presents a preliminary example of the supply of Coca-Cola beverages into school vending machines and identifies further potential applications. These include fruit and vegetable supply chains, local food chains, supply chains for health-promoting versions of food products, and identifying financial incentives in supply chains for healthier eating.

2016-12-01

We explore how a global shift in the food system caused by global economic growth, increase in available food per capita and in food processing is a driver of the obesity epidemic. Economic development in most areas of the world has resulted in increased purchasing power and available per capita food. Supermarkets and a growing fast-food industry have transformed our dietary pattern. Ultra-processed food rich on sugars and saturated fat is now the major source of energy in most countries. The shift in food supply is considered a major driver of the obesity epidemic and the increasing prevalence of accompanying complications, such as type 2 diabetes, cardiovascular disease and cancer. However, the global shift might also have direct effects on the increase in type 2 diabetes, cardiovascular disease and cancer, independently of overweight and obesity. The shift in the food supply is a major driver of the obesity epidemic.
Reducing ethylene levels along the food supply chain: a key to reducing food waste?

Science.gov (United States)

Blanke, Michael M

2014-09-01

Excessive waste along the food supply chain of 71 (UK, Netherlands) to 82 (Germany) kg per head per year sparked widespread criticism of the agricultural food business and provides a great challenge and task for all its players and stakeholders. Origins of this food waste include private households, restaurants and canteens, as well as supermarkets, and indicate that 59-65% of this food waste can be avoided. Since ∼50% of the food waste is fruit and vegetables, monitoring and control of their natural ripening gas - ethylene - is suggested here as one possible key to reducing food waste. Ethylene accelerates ripening of climacteric fruits, and accumulation of ethylene in the supply chain can lead to fruit decay and waste. While ethylene was determined using a stationary gas chromatograph with gas cylinders, the new generation of portable sensor-based instruments now enables continuous in situ determination of ethylene along the food chain, a prerequisite to managing and maintaining the quality and ripeness of fruits and identifying hot spots of ethylene accumulation along the supply chain. Ethylene levels were measured in a first trial, along the supply chain of apple fruit from harvest to the consumer, and ranged from 10 ppb in the CA fruit store with an ethylene scrubber, 70 ppb in the fruit bin, to 500 ppb on the sorting belt in the grading facility, to ppm levels in perforated plastic bags of apples. This paper also takes into account exogenous ethylene originating from sources other than the fruit itself. Countermeasures are discussed, such as the potential of breeding for low-ethylene fruit, applications of ethylene inhibitors (e.g. 1-MCP) and absorber strips (e.g. 'It's Fresh', Ryan'), packages (e.g. 'Peakfresh'), both at the wholesale and retail level, vents and cooling for the supply chain, sale of class II produce ('Wunderlinge'), collection (rather than waste) of produce on the 'sell by' date ('Die Tafel') and whole crop purchase (WCP) to aid reducing

The Impact of Food Quality Information Services on Food Supply Chain Pricing Decisions and Coordination Mechanisms Based on the O2O E-Commerce Mode

2018-01-01

Full Text Available This paper considers the price conflict problem between the online channel of a food processing factory and the offline channel of the food retailers in food supply chains by analyzing the pricing decisions and coordination mechanisms between the food processing factory and food retailers under the influence of a food quality information service. First, the Stackelberg game method and the Bertrand game method are used to optimize the pricing decisions with the goal of maximizing the profits of the food processing factory and retailer. The analysis shows that the food quality information service level is positively correlated with the price of the factory’s own channel, and the influence of the food quality information service level on the price of the food processing factory’s or the food retailer’s own channel is stronger than its influence on the price of a competitor’s channel. Second, the food supply chain members’ pricing decisions are analyzed using the case analysis method by considering practical problems in the food supply chain. The results indicate that the food processing factory should use the Stackelberg game to make pricing decisions. However, it is optimal for the food retailer to make pricing decisions under the Bertrand game, and the total profit of the food supply chain is optimized under centralized decision making. Finally, we use both the quantitative discount mechanism and the Stackelberg game method to analyze the profits obtained by the food processing factory and retailer. The results indicate that the food processing factory should implement a quantitative discount mechanism when the quantity discount coefficient is greater than 0.4, and the retailer should implement a quantity discount mechanism when the quantity discount coefficient is in the range of 0.25 to 0.4.

Invasion of ocean surface waters by anthropogenic CO2 emitted to the atmosphere is expected to reduce surface seawater pH to 7.8 by the end of this century compromising marine calcifiers. A broad range of biological and mineralogical mechanisms allow marine calcifiers to cope with ocean acidification, however these mechanisms are energetically demanding which affect other biological processes (trade-offs) with important implications for the resilience of the organisms against stressful conditions. Hence, food availability may play a critical role in determining the resistance of calcifiers to OA. Here we show, based on a meta-analysis of existing experimental results assessing the role of food supply in the response of organisms to OA, that food supply consistently confers calcifiers resistance to ocean acidification.

Alexandra Ioana IONESCU FLOREA

2016-06-01

Full Text Available Food crisis are always of big concern for the consumers and governments. Complex supply chains make it more difficult for all actors involved to manage such a crisis. Companies in the food industry must respond now not only to the concerns of customers about the food safety, but also to their need for fresh and healthy products. Together with governments, to enforce regularly the legislation, customers affect the way food actors conduct their business, and can have a great impact on the food supply chain. In order to answer these needs, companies have to modify their supply chains and operate with more transparency, taking into account the demands for traceability. The objective of this article is to analyze how customers and governments trigger more transparency from the food companies and supply chains, the opportunities and challenges of implementing and communicating transparency and traceability.

Managing Food Quality Risk in Global Supply Chain: A Risk Management Framework

Directory of Open Access Journals (Sweden)

Pablo Jose Arevalo Chavez

2012-04-01

Full Text Available Today, the food sector is one of the sectors most vulnerable to intentional contamination by debilitating agents [1]. Some cases of contaminated food have indicated that product quality risk is one of the vulnerabilities in the global supply chain. A series of company scandals, affecting reputation and causing the recall of products and increasing costs have hit the food industry. The obvious problem is that even a minor incident in one part of the chain can have disastrous effects on other parts of the supply chain. Thus, risks are transmitted through the chain. Even though the dangers from members in the supply chain are small, the cumulative effect becomes significant. The aim of this study is to propose an integrated supply chain risk management framework for practitioners that can provide directions for how to evaluate food quality risk in the global supply chain. For validating the proposed model in‐depth, a case study is conducted on a food SME distributor in Central America. The case study investigates how product quality risks are handled according to the proposed framework.
Food supply depends on seagrass meadows in the coral triangle

Unsworth, Richard K F; Hinder, Stephanie L; Bodger, Owen G; Cullen-Unsworth, Leanne C

2014-01-01

The tropical seascape provides food and livelihoods to hundreds of millions of people, but the support of key habitats to this supply remains ill appreciated. For fisheries and conservation management actions to help promote resilient ecosystems, sustainable livelihoods, and food supply, knowledge is required about the habitats that help support fisheries productivity and the consequences of this for food security. This paper provides an interdisciplinary case study from the coral triangle of how seagrass meadows provide support for fisheries and local food security. We apply a triangulated approach that utilizes ecological, fisheries and market data combined with over 250 household interviews. Our research demonstrates that seagrass associated fauna in a coral triangle marine protected area support local food supply contributing at least 50% of the fish based food. This formed between 54% and 99% of daily protein intake in the area. Fishery catch was found to significantly vary with respect to village (p < 0.01) with habitat configuration a probable driver. Juvenile fish comprised 26% of the fishery catch and gear type significantly influenced this proportion (<0.05). Limited sustainability of fishery practices (high juvenile catch and a 51% decline in CPUE for the biggest fishery) and poor habitat management mean the security of this food supply has the potential to be undermined in the long-term. Findings of this study have implications for the management and assessment of fisheries throughout the tropical seascape. Our study provides an exemplar for why natural resource management should move beyond biodiversity and consider how conservation and local food security are interlinked processes that are not mutually exclusive. Seagrass meadows are under sustained threat worldwide, this study provides evidence of the need to conserve these not just to protect biodiversity but to protect food security. (letter)

Full Text Available Many companies have captured and analyzed huge volumes of data to improve the decision mechanism of supply chain, this paper presents a big data harvest model that uses big data as inputs to make more informed decisions in the food supply chain. By introducing a method of Bayesian network, this paper integrates sample data and finds a cause-and-effect between data to predict market demand. Then the deduction graph model that translates foods demand into processes and divides processes into tasks and assets is presented, and an example of how big data in the food supply chain can be combined with Bayesian network and deduction graph model to guide production decision. Our conclusions indicate that the decision-making mechanism has vast potential by extracting value from big data.

One of the most challenging tasks in today's food industry is controlling the product quality throughout the food supply chain. In this paper, we integrate food quality in decision-making on production and distribution in a food supply chain. We provide a methodology to model food quality...... degradation in such a way that it can be integrated in a mixed-integer linear programming model used for production and distribution planning. The resulting model is applied in an illustrative case study, and can be used to design and operate food distribution systems, using both food quality and cost...
Quality and Operations Management in Food Supply Chains: A Literature Review

Yong He

2018-01-01

Full Text Available We present a literature review on quality and operations management problems in food supply chains. In food industry, the quality of the food products declines over time and should be addressed in the supply chain operations management. Managing food supply chains with operations management methods not only generates economic benefit, but also contributes to environmental and social benefits. The literature on this topic has been burgeoning in the past few years. Since 2005, more than 100 articles have been published on this topic in major operations research and management science journals. In this literature review, we concentrate on the quantitative models in this research field and classify the related articles into four categories, that is, storage problems, distribution problems, marketing problems, and food traceability and safety problems. We hope that this review serves as a reference for interested researchers and a starting point for those who wish to explore it further.

Competitiveness of Small Farms and Innovative Food Supply Chains: The Role of Food Hubs in Creating Sustainable Regional and Local Food Systems

Directory of Open Access Journals (Sweden)

Giaime Berti

2016-07-01

Full Text Available Over the last decades, the economic, social and environmental sustainability of the conventional agri-food system has and continues to be contested within both academic and public institutions. For small farms, the unsustainability of the food system is even more serious; farms’ declining share of profit and the cost-price squeeze of commodity production has increased barriers to market access with the inevitable effect of agricultural abandonment. One way forward to respond to the existing conventional agri-food systems and to create a competitive or survival strategy for small family farms is the re-construction of regional and local agri-food systems, aligning with Kramer and Porter’s concept of shared value strategy. Through a critical literature review, this paper presents “regional and local food hubs” as innovative organizational arrangements capable of bridging structural holes in the agri-food markets between small producers and the consumers—individuals and families as well as big buyers. Food hubs respond to a supply chain (or supply network organizational strategy aiming at re-territorialising the agri-food systems through the construction of what in the economic literature are defined as values-based food supply chains.

Menaquinones, bacteria, and the food supply: the relevance of dairy and fermented food products to vitamin K requirements.

Walther, Barbara; Karl, J Philip; Booth, Sarah L; Boyaval, Patrick

2013-07-01

Vitamin K exists in the food supply as phylloquinone, a plant-based form and as menaquinones (MKs), a collection of isoprenologues mostly originating from bacterial synthesis. Although multiple bacterial species used as starter cultures for food fermentations synthesize MK, relatively little is known about the presence and distribution of MK in the food supply and the relative contribution of MK to total dietary vitamin K intake. Dairy products may be a predominant source of dietary MK in many regions of the world, and there is recent interest in enhancing the MK content of dairy products through identification and selection of MK-producing bacteria in dairy fermentations. This interest is increased by emerging evidence that current dietary recommendations based on the classic role of vitamin K as an enzyme cofactor for coagulation proteins may not be optimal for supporting vitamin K requirements in extrahepatic tissues and that MK may have unique bioactivity beyond that as an enzyme cofactor. Observational studies have reported favorable associations between MK intake and bone and cardiovascular health. Although randomized trials have provided some evidence to support the beneficial effects of MK on bone, the evidence to date is not definitive, and randomized trials have not yet examined MK intake in relation to cardiovascular outcomes. Food production practices provide a means to enhance dietary MK availability and intake. However, parallel research is needed to optimize these production practices, develop comprehensive food MK content databases, and test hypotheses of unique beneficial physiological roles of MK beyond that achieved by phylloquinone.

While a growing proportion of global food consumption is obtained through international trade, there is an ongoing debate on whether this increased reliance on trade benefits or hinders food security, and specifically, the ability of global food systems to absorb shocks due to local or regional losses of production. This paper introduces a model that simulates the short-term response to a food supply shock originating in a single country, which is partly absorbed through decreases in domestic reserves and consumption, and partly transmitted through the adjustment of trade flows. By applying the model to publicly-available data for the cereals commodity group over a 17 year period, we find that differential outcomes of supply shocks simulated through this time period are driven not only by the intensification of trade, but as importantly by changes in the distribution of reserves. Our analysis also identifies countries where trade dependency may accentuate the risk of food shortages from foreign production shocks; such risk could be reduced by increasing domestic reserves or importing food from a diversity of suppliers that possess their own reserves. This simulation-based model provides a framework to study the short-term, nonlinear and out-of-equilibrium response of trade networks to supply shocks, and could be applied to specific scenarios of environmental or economic perturbations.
Food supply and bioenergy production within the global cropland planetary boundary.

Supplying food for the anticipated global population of over 9 billion in 2050 under changing climate conditions is one of the major challenges of the 21st century. Agricultural expansion and intensification contributes to global environmental change and risks the long-term sustainability of the planet. It has been proposed that no more than 15% of the global ice-free land surface should be converted to cropland. Bioenergy production for land-based climate mitigation places additional pressure on limited land resources. Here we test normative targets of food supply and bioenergy production within the cropland planetary boundary using a global land-use model. The results suggest supplying the global population with adequate food is possible without cropland expansion exceeding the planetary boundary. Yet this requires an increase in food production, especially in developing countries, as well as a decrease in global crop yield gaps. However, under current assumptions of future food requirements, it was not possible to also produce significant amounts of first generation bioenergy without cropland expansion. These results suggest that meeting food and bioenergy demands within the planetary boundaries would need a shift away from current trends, for example, requiring major change in the demand-side of the food system or advancing biotechnologies.

Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth phase, food supply may play a key role in the response of marine organisms to OA. We experimentally evaluated the role of food supply in modulating physiological responses and biomineralization processes in juveniles of the Chilean scallop, Argopecten purpuratus, that were exposed to control (pH ~ 8.0) and low pH (pH ~ 7.6) conditions using three food supply treatments (high, intermediate, and low). We found that pH and food levels had additive effects on the physiological response of the juvenile scallops. Metabolic rates, shell growth, net calcification, and ingestion rates increased significantly at low pH conditions, independent of food. These physiological responses increased significantly in organisms exposed to intermediate and high levels of food supply. Hence, food supply seems to play a major role modulating organismal response by providing the energetic means to bolster the physiological response of OA stress. On the contrary, the relative expression of chitin synthase, a functional molecule for biomineralization, increased significantly in scallops exposed to low food supply and low pH, which resulted in a thicker periostracum enriched with chitin polysaccharides. Under reduced food and low pH conditions, the adaptive organismal response was to trade-off growth for the expression of biomineralization molecules and altering of the organic composition of shell periostracum, suggesting that the future performance of these calcifiers will depend on the trajectories of both OA and food supply. Thus, incorporating a suite of traits and multiple stressors in future studies of the adaptive organismal response may provide key insights on OA impacts on marine calcifiers.

The relationship of cancer mortality to life span and food supply rate

Totter, J.R.; Adler, H.I.; Storer, J.B.

Survival curves for men and women dying from cardiovascular disease and similar curves for those dying from cancer in 47 countries were compared with the 1970-1974 per capita incomes of the inhabitants. The data were taken chiefly from 1964 life tables. The steepest survival curves were found in countries with the highest incomes. Comparison of the survival curves in different countries and comparison of cardiovascular survival with cancer survival curves indicate that both groups of diseases are probably diseases of senescence. The differences in survival slopes are interpreted as homeostatic responses in the population to rate of food intake. The response protects the population against long-term effects of changes in food supply by promoting differential reproduction of offspring best suited to the food supply rate fro the environment. The response to food supply rate complicates calculation of the effects of protracted exposure to low-level ionizing radiation because the radiation exposure appears to mimic the effec of extra food
Potentials and Limitations of Regional Organic Food Supply: A Qualitative Analysis of Two Food Chain Types in the Berlin Metropolitan Region

Full Text Available Regional food systems and organic agriculture are both considered more sustainable than the conventional, globalized food system they provide an alternative to. The emergence and expansion of alternative forms of food supply are influenced by various factors on different scales. Using the food systems approach we aim to study potentials and limitations of regional organic food supply in the Berlin metropolitan region (BMR. Based on the literature, we developed an analytical framework and identified determinants of regional organic food provision along the three major levels of the supply chain: agricultural production, food chain organization, and consumption. Then, we examined a qualitative case study with two different types of alternative food networks (A organic community supported agriculture (CSA and (B organic retail trade. Factors that hinder or promote the provision of regional organic food were identified through qualitative interviews and assessed by regional stakeholders in a workshop. Our findings show that demand for regional organic food is higher than regional supply, which could offer good possibilities for organic farmers. However, actors in these two food chains need to overcome some obstacles, including limited access to land, increasing renting prices, insufficient processing capacities, and unsupportive political environment for organic farming.

Ashenafi Chaka

2016-07-01

Full Text Available Warqe (Enset is a multipurpose perennial plant, domesticated and grown as a food crop only in Ethiopia. Kocho, bulla, and amicho are food products of warqe. This study analysed the supply chain and logistics practices of warqe foods. Supply chain management concept was used to analyse the warqe-based food chain. Eight supply chain actors were identified. It was observed that the supply chain of warqe foods and the relationship between chain actors was very complex, long and overlapping. The major constraints identified in the chain were poor information flow, poor transportation system, using perishable packaging, lack of cooperation between actors, a poor infrastructure such as road and warehouse services, and poor policies concerning the warqe market. There is a need for cooperation and coordination between the chain actors to create an effective information sharing system. Shared warehouses need to be built near producers and market places. Transportation, packaging and handling need to be improved. Research is required to develop an integrated, efficient and effective logistics for warqe supply and marketing chain.
Dynamic impact of the structure of the supply chain of perishable foods on logistics performance and food security

Understanding how the structure affects logistical performance and food security is critical in the supply chains of perishable foods (PFSC). This research proposes a system dynamics model to analyze the effects of structures: lean, agile, flexible, responsive and resilient, in the overall performance and of each agent of the PFSC. Design/methodology/approach: Using a system dynamics model and design of experiments it is studied how the different structures and their combination, affect the behavior of inventory, transportation, responsiveness, efficiency, availability and quality-safety of the fresh fruits supply chain and each echelon. Findings: The studies of supply chains have been done for each structure in an independent way; investigations are scarce in supply chains of perishable foods. The structures modeled in this research do not show the better performance in all the metrics of the chain, neither in all agents for each structure. The above implies the presence of trade-offs. Research limitations/implications: The results show the need to investigate mixed structures with the FPSC´s own characteristics; the model can be applied in other supply chains of perishable foods. Practical implications: Management by combining structures in the FFSC, improves logistics performance and contributes to food security. Social implications: The agents of the FFSC can apply the structures found in this study, to improve their logistics performance and the food security. Originality/value: The dynamics of individual and combined structures were identified, which constitutes a contribution to the discussion in the literature of such problems for FFSC. The model includes six echelons: farmers, wholesalers, agro-industry, third-party logistics operators and retailers. The dynamic contemplates deterioration rate to model perishability and others losses.

To reach this aim, different methodological approaches were applied to analyze this issue, to experiment with different aspects, and to test the resulting interventions. Each of these approaches was undertaken by competent consortium partners from Denmark, Germany, Norway, Sweden and The Netherlands. The project finally provides validated strategies to promote the distribution and consumption of suboptimal foods, thereby improving resource efficiency in the food chain and contributing to a more sustainable food supply.

Full Text Available In order to prevent and control risk factors which harm the quality and safety of the food supply chain effectively and reduce the probability of food safety incidents, this paper investigated on some problems of the upstream and downstream enterprises of the food supply chain under the three different forms of cooperation based on the neoclassic economics and game theory method. These problems include the effectiveness of the quality and safety efforts, the profits, the effect of the losses that the food safety incidents caused on the quality efforts’ efficacy, and the social welfare comparison. Meanwhile, we constructed evolutionary game model to analyze the macro and micro factors that influenced the cooperation strategy and demonstrated the effect of diversity of decision-making parameters on evolution results based on numerical simulation. By the theoretical and simulation analysis, we found that (1 the quality efforts’ efficacy, the profits, the sensitivity coefficient of the quality efforts efficiency to the losses, and the social welfare without thinking about the externality all met their maximum under the full cooperation situation; (2 strengthening supervision over the source of the food supply chain can reduce the probability of food safety incidents; (3 macro and micro environment will be the important basis for companies’ decision-making on cooperation strategy in the food supply chain.

A food supply that delivers energy-dense products with high levels of salt, saturated fats and trans fats, in large portion sizes, is a major cause of non-communicable diseases (NCDs). The highly processed foods produced by large food corporations are primary drivers of increases in consumption of these adverse nutrients. The objective of this paper is to present an approach to monitoring food composition that can both document the extent of the problem and underpin novel actions to address it. The monitoring approach seeks to systematically collect information on high-level contextual factors influencing food composition and assess the energy density, salt, saturated fat, trans fats and portion sizes of highly processed foods for sale in retail outlets (with a focus on supermarkets and quick-service restaurants). Regular surveys of food composition are proposed across geographies and over time using a pragmatic, standardized methodology. Surveys have already been undertaken in several high- and middle-income countries, and the trends have been valuable in informing policy approaches. The purpose of collecting data is not to exhaustively document the composition of all foods in the food supply in each country, but rather to provide information to support governments, industry and communities to develop and enact strategies to curb food-related NCDs. © 2013 The Authors.

Population growth to put pressure on some food supplies.

Science.gov (United States)

1997-01-01

Continued high population growth in developing countries is likely to lead to intense pressure to produce more rice, according to estimates from the Manila-based International Rice Research Institute (IRRI). Ms. Mercedita Sombilla, a research scientist with IRRI, said that the projected increase in Asia's population will be the major force in accelerating demand for rice. According to various issues of the ESCAP Population Data Sheet, the population of the region will have increased from 3.3 billion in 1995 to almost 4.6 billion in 2020. The greatest growth in demand is expected to come from the lower-income countries of Asia, such as Bangladesh, India, Myanmar, Philippines, and Viet Nam, she said. However, in terms of overall food supplies, the Organization for Economic Cooperation and Development (OECD) estimates that food supplies will be sufficient. "Expecting reasonably strong productivity growth to be sustainable, no global food crisis seems likely to occur" between now and 2020, the organization stated in its report entitled "The World in 2020: Towards a New Global Age". full text

Frequent family meals and home food preparation are considered important for children's nutritional health and weight maintenance. This cross-sectional study tested whether these parent-driven behaviors are related to the availability of food preparation supplies in low-income urban households. Caregivers of children ages 6-13 provided information on family meal frequency, child consumption of home-prepared dinners, household food insecurity, and attitudes towards cooking. Researchers used a newly developed Food Preparation Checklist (FPC) to assess the availability of 41 food preparation supplies during a physical audit of the home environment. Caregivers and children provided anthropometric measurements and jointly reported on child dietary intake. In ordinal logistic regression models, greater home availability of food preparation supplies was associated with more frequent family meals and child consumption of home-prepared dinners. Associations were independent of household financial strain, food insecurity, caregiver attitudes toward cooking, and sociodemographic characteristics. Fewer food preparation supplies were available in households characterized by greater food insecurity, lower income, and negative caregiver attitudes towards cooking, but did not differ by child or caregiver weight status. As in prior studies, more frequent family meals and consumption of home-prepared dinners were associated with healthier child dietary intake in several areas. We conclude that food preparation supplies are often limited in the most socioeconomically disadvantaged households, and their availability is related to the frequency with which children consume family meals and home-prepared dinners. The potential role of food preparation supplies as contributors to socioeconomic disparities in child nutritional health and obesity deserves further study. Copyright © 2014 Elsevier Ltd.

Full Text Available Today, the global business environment compels enterprises to consider rest of the world in their competitive strategy analysis where firms ignore external factors such as economic trends, competitive positions or technology advancement in other countries. While going truly global with supply chain management, a company develops product in the United States, produce in India and trade in Europe, and they have changed the traditional operation management & logistical activities. This change in trade and the modernization of transport infrastructures have elevated the importance of flow management to new levels. Manufacturers and researchers have noticed many problems concerning supply chain activities, and usually either a system or subcomponent in supply chains is discussed in the literature, but they fails to answer the rational (why, what, how behind them. This paper addresses a review of the principles, bottlenecks and strategies of supply chain practices for organizations with an emphasis on the implications of Indian agri-food sector. Findings of this review reveal that the human & environmental issues, improved product visibility, food safety/quality and the associated economic benefits in sustainable agri-food supply chains can be achieved through innovation, collaboration, elimination of uncertainties and introducing global SCM practices into green & lean initiatives.

Full Text Available Food supply in the nesting territories of species has a key role to the species diet composition and their breeding success. Red-footed falcon (Falco vespertinus preys predominantly on larger insect species with a supplementary portion of smaller vertebrates. In the breeding periods 2014 and 2016 their food supply, focusing on Orthoptera, Mantodea, Rodentia and Eulipotyphla, was analysed at five historical nesting sites of the species in Slovakia. Preference for these prey groups in the diet was also studied at the last active nesting site in this country. Overall we recorded 45 Orthoptera species (of which 23 species are known as the food of the red-footed falcon, one species of Mantodea, 10 species of Rodentia (of which 2 species are known as the food of the red-footed falcon and 5 species of the Eulipotyphla order in the food supply. With regard to the availability of the falcons' preferred food, in both years the most suitable was the Tvrdošovce site, which continuously showed the greatest range and abundance of particular species. In the interannual comparison the insects showed lower variability in abundance than the small mammals. In 2014 the growth of the common vole (Microtus arvalis population culminated and with the exception of a single site (Bodza a slump in abundance was recorded in 2016. In comparing the diet composition with the food supply at the last Slovak breeding site Rusovce (Special Protection Area Sysľovské polia, we recorded significant preference for grasshopper Caliptamus italicus (in 2014, common vole (in 2016 and cricket Tettigonia viridissima (in both years in the falcons' diet. They did not prey on the Apodemus sylvaticus species belonging among the abundant small mammal species in that locality. Conservation measures in the agricultural landscape are discussed in relation to homogeneous red-footed falcon breeding territories.

To compare quality, quantity, and trends of food supply from 1984 to 2009 and degree of food westernization in Taiwan with Asian countries and world continents by using food balance data. We compiled data from food balance sheets of Taiwan and Food and Agriculture Organization, including five continents and three most populated countries each in Eastern, Southern, and Southeastern Asia over the period 1984-2009. Quantity of food supply per capita was referenced to Taiwan food guides. The population-weighted means of food supply from Europe, North America, South America, and Australia and New Zealand continents in terms of energy and nutrient distributions, animal/plant sources, and sugar/alcohol contribution were used as indicators of westernization. Trends of food supply per capita of six food groups were plotted, and linear regression was applied to evaluate food changes. Taiwan's food supply provided sufficient quantity in food energy, with the lowest cereals/roots supply and rice to wheat ratio, but the highest meat and oil supplies per capita among the 10 studied Asian countries. Taiwan food supply showed the most westernization among these countries. Food supply of Taiwan, although currently sufficient, indicated some security problems and high tendency of diet westernization.

Phosphorus-based food additives may pose a significant risk in chronic kidney disease given the link between hyperphosphatemia and cardiovascular disease. The objective of the study was to determine the prevalence of phosphorus-based food additives in best-selling processed grocery products and to establish how they were reported on food labels. A data set of 3000 best-selling grocery items in Australia across 15 food and beverage categories was obtained for the 12 months ending December 2013 produced by the Nielsen Company's Homescan database. The nutrition labels of the products were reviewed in store for phosphorus additives. The type of additive, total number of additives, and method of reporting (written out in words or as an E number) were recorded. Presence of phosphorus-based food additives, number of phosphorus-based food additives per product, and the reporting method of additives on product ingredient lists. Phosphorus-based additives were identified in 44% of food and beverages reviewed. Additives were particularly common in the categories of small goods (96%), bakery goods (93%), frozen meals (75%), prepared foods (70%), and biscuits (65%). A total of 19 different phosphorus additives were identified across the reviewed products. From the items containing phosphorus additives, there was a median (minimum-maximum) of 2 (1-7) additives per product. Additives by E number (81%) was the most common method of reporting. Phosphorus-based food additives are common in the Australian food supply. This suggests that prioritizing phosphorus additive education may be an important strategy in the dietary management of hyperphosphatemia. Further research to establish a database of food items containing phosphorus-based additives is warranted. Copyright © 2015 National Kidney Foundation, Inc. Published by Elsevier Inc.

To determine the level of community concern about future food supplies and perception of the importance placed on government regulation over the supply of environmentally friendly food and identify dietary and other factors associated with these beliefs in Western Australia. Data from the 2009 and 2012 Nutrition Monitoring Survey Series computer-assisted telephone interviews were pooled. Level of concern about the effect of the environment on future food supplies and importance of government regulating the supply of environmentally friendly food were measured. Multivariate regression analysed potential associations with sociodemographic variables, dietary health consciousness, weight status and self-reported intake of eight foods consistent with a sustainable diet. Western Australia. Community-dwelling adults aged 18-64 years (n = 2832). Seventy nine per cent of Western Australians were 'quite' or 'very' concerned about the effect of the environment on future food supplies. Respondents who paid less attention to the health aspects of their diet were less likely than those who were health conscious ('quite' or 'very' concerned) (OR = 0.53, 95% CI [0.35, 0.8] and 0.38 [0.17, 0.81] respectively). The majority of respondents (85.3%) thought it was 'quite' or 'very' important that government had regulatory control over an environmentally friendly food supply. Females were more likely than males to rate regulatory control as 'quite' or 'very' important' (OR = 1.63, 95% CI [1.09, 2.44], p = .02). Multiple regression modeling found that no other factors predicted concern or importance. There is a high level of community concern about the impact of the environment on future food supplies and most people believe it is important that the government regulates the issue. These attitudes dominate regardless of sociodemographic characteristics, weight status or sustainable dietary behaviours. Copyright © 2018 Elsevier Ltd. All rights reserved.
Strategies and Tools for Eco-Efficient Local Food Supply Scenarios

Paola Caputo

2014-01-01

Full Text Available Considering the wide demand for daily meals, the issue of the institutional food system has become very important in highly developed societies and, also, how it affects the flow of energy and matter within a territory. This research originates from a wide multi-disciplinary project aimed at developing a self-sufficient approach to improve the institutional food system in an area of Northern Italy. Thus, the aim of this research is to give some guidelines to implement ideal scenarios of food production, processing, consumption, and waste management at the local level. To that end, the organization of the supply and demand within the local institutional food system is inquired. A methodology has been developed to analyze the main energy flows and matter related to this catering, and to outline possible optimal scenarios. This methodology also allows to analyze case studies and to formulate improvements in order to reduce their energy consumption while exploring all the steps of the supply chain (considering the Life Cycle Assessment (LCA approach. The use of quantitative indicators allows a comparison of the impacts related to the different steps characterizing the suggested scenarios. This paper presents results related to a test in the context of institutional catering in public schools.

Food supply mechanisms for cold-water corals along a continental shelf edge

Science.gov (United States)

Thiem, Øyvind; Ravagnan, Elisa; Fosså, Jan Helge; Berntsen, Jarle

2006-05-01

In recent years it has been documented that deep-water coral reefs of the species Lophelia pertusa are a major benthic habitat in Norwegian waters. However, basic information about the biology and ecology of this species is still unknown. Lophelia live and thrive under special environmental conditions of which factors such as temperature, water depth, water movement and food supply are important. The present work explores the hypothesis that Lophelia forms reefs in places where the encounter rate of food particles is sufficiently high and stable over long periods of time for continuous growth. This is done by relating the distribution of reefs with the results of numerical ocean modelling. Numerical simulations have been performed with an idealized bottom topography similar to what is found outside parts of the Norwegian coast. In the simulations the model is first forced with an along slope jet and then with an idealized atmospheric low pressure. The model results show that the encounter rates between the particles and the water layer near the seabed are particularly high close to the shelf break. This may indicate that many Lophelia reefs are located along the shelf edges because the supply of food is particularly good in these areas. A sensitivity study of the particle supply in the area close to the seabed for increasing latitude has also been done. This shows that the Ekman transport in the benthic layer tends to create a steady supply of food for benthic organisms near the shelf edge away from the equator.

Self-Sufficiency versus Security: How Trade Protectionism Challenges the Sustainability of the Food Supply in Russia

Directory of Open Access Journals (Sweden)

Vasilii Erokhin

2017-10-01

Full Text Available Food security is increasingly influenced by multilateral trade systems and foreign trade policies implemented by national governments. Many of them are now concerned about the sustainability of food supply and the vulnerability of domestic food markets to price volatility, and seek to support domestic producers and protect themselves from increasing food imports. Such restrictions improve food self-sufficiency, but decrease food security. It is important to understand any changes that may have occurred in the food consumption pattern due to trade protectionism and to observe any nutritional implications of these changes. This paper employs the rational food security (RFS assessment approach, which differentiates sources of food supply on the domestic market, assesses the influence of agricultural and trade frameworks on food consumption patterns, and complies consumption with the appropriate food intake threshold. In the case of Russia, the study demonstrates that the conventional consumption approach to self-sufficiency (FSCA underestimates the food insecurity level by not accounting for nutrition factors. In addition, the gap between the FSCA and the RFS increases in times of protectionist trade policy and decreases when the agricultural and trade policy framework turns to liberalization. The paper concludes that trade protectionism challenges the sustainability of food supply by decreasing food availability and quality of food products, causes dietary changes, and threatens the food security of the country.

Direct analysis in real time (DART) represents a new generation of ion source which is used for rapid ionization of small molecules under ambient conditions. The combination of DART and various mass spectrometers allows analyzing multiple food samples with simple or no sample treatment, or in conjunction with prevailing protocolized sample preparation methods. Abundant applications by DART-MS have been reviewed in this paper. The DART-MS strategy applied to food supply chain (FSC), including production, processing, and storage and transportation, provides a comprehensive solution to various food components, contaminants, authenticity, and traceability. Additionally, typical applications available in food analysis by other ambient ionization mass spectrometers were summarized, and fundamentals mainly including mechanisms, devices, and parameters were discussed as well. © 2015 Wiley Periodicals, Inc.

Harris, J.

2012-01-01

This presentation will examine the direct application of nuclear energy solutions in the north, and remote areas of Canada. Further it will challenge the existing energy network based on the shipment of fossil fuels to remote areas, and examine the use of small, modular, and/or deployable nuclear plants in these communities. The use of these small reactors and some newly emerging technologies will likely provide a near total energy supply for these communities. In particular low grade heat processes, district heating, the 'local' production of motive fuels, and local food production will be examined. Additionally the economic and social impact of moving the value added side of many of these processes to the local communities will also be briefly discussed.

Arsenic (As) is a metalloid that occurs in different inorganic and organic forms, which are found in the environment from both natural occurrence and anthropogenic activity. The inorganic forms of As (iAs) are more toxic as compared with the organic As, but so far most of the occurrence data in food collected in the framework of official food control are still reported as total As without differentiating the various As species. In this paper, total As and iAs contents of 600 total diet study (TDS) samples, subdivided into 15 different food groups, were quantified by high-resolution inductively coupled plasma mass spectrometry (HR-ICP/MS) and hydride generation (HG) ICP/MS respectively. The method detection limits for both total As and iAs were 3 μg As kg(-1). As the samples were prepared for TDS, food items were purchased directly from the market or prepared as for normal consumption, i.e. table ready, in the manner most representative of and consistent with cultural habits in Hong Kong as far as practicable. The highest total As and iAs content were found in 'fish, seafood and their products' and 'vegetables and their products' respectively. Besides, this paper also presents the ratios of iAs and total As content in different ready-to-eat food items. The highest ratio of iAs to total As was found in 'vegetables and their products'. It is likely that iAs in vegetables maintained its status even after cooking.

Heising, Jenneke K; Claassen, G D H; Dekker, Matthijs

2017-10-01

Optimising supply chain management can help to reduce food waste. This paper describes how intelligent packaging can be used to reduce food waste when used in supply chain management based on quality-controlled logistics (QCL). Intelligent packaging senses compounds in the package that correlate with the critical quality attribute of a food product. The information on the quality of each individual packaged food item that is provided by the intelligent packaging can be used for QCL. In a conceptual approach it is explained that monitoring food quality by intelligent packaging sensors makes it possible to obtain information about the variation in the quality of foods and to use a dynamic expiration date (IP-DED) on a food package. The conceptual approach is supported by quantitative data from simulations on the effect of using the information of intelligent packaging in supply chain management with the goal to reduce food waste. This simulation shows that by using the information on the quality of products that is provided by intelligent packaging, QCL can substantially reduce food waste. When QCL is combined with dynamic pricing based on the predicted expiry dates, a further waste reduction is envisaged.

System analysis was performed to gain an overview of key environmental challenges and pinpoint hotspots causing environmental impacts in three European food supply chains. An overview was obtained based on a review on LCA studies for beef, dairy, orange juice and aquaculture food supply chains....... Similarities of the main environmental impacts were identified to rationalize and justify the selection of key performance indicators chosen for a simplified web based LCA tool developed within the EC funded project SENSE (FP7). Life Cycle Assessment methodology covered many of the key challenges identified...... but will not be sufficient to address all environmental impacts generated from the food supply chains. Especially for aquaculture impacts that are not taken into account with LCA are i.e. nutrient and organic matter releases, impacts associated with feed provision, diseases introduction, escapes, and changed usage...
Towards a More Sustainable Food Supply Chain: Opening up Invisible Waste in Food Service

2016-07-01

Full Text Available Future challenges to the global food supply chain are complex. In order to embrace sustainability, companies should change their management practices towards more efficient resource use. Food waste being a misuse of resources, we identify its causes and possible ways of minimising it. To achieve this goal, we conducted explorative research with qualitative and quantitative data through in-depth semi-structured interviews and an open questionnaire with top Spanish food service companies. Results show that most businesses mainly tend to minimise food waste according to economic criteria, without taking into account the social, ethical or environmental factors. As a consequence, just “visible” food waste that has an economic impact on the results is minimised. Nevertheless, visibility of real waste is often low. At the same time, awareness of (and therefore initiatives to reduce food waste that does not directly affect a firm’s profit can be increased through multi-stakeholder collaboration. Opportunities for reducing food waste therefore arise from increasing the visibility of food that is discarded as well as addressing plate waste. We identify best practices that could lead to a reduction of the amount of food waste generated in the out of home channel in Spain.

Dietary trans fatty acids (TFAs) increase the risk of heart disease. In 2007, Canada set voluntary TFA limits for industrial TFAs added to food and encouraged substitution of TFAs with unsaturated fats during reformulation. No longitudinal follow-up assessment of TFA amounts in foods has occurred in Canada since termination of a government-led Trans Fat Monitoring Program (TFMP). The objective was to conduct an updated assessment and longitudinally evaluate TFA amounts in the food supply and to determine whether saturated fats have replaced TFAs in reformulation. This was a cross-sectional study that used 3 databases: TFMP (Health Canada, 2005-2009; n = 921), the University of Toronto Food Label Information Program (2010-2011; n = 5544), and the Restaurant Database (2010; n = 4272). Outcomes were TFAs as a percentage of fat, proportion of foods meeting TFA limits, and saturated fat amounts in foods with high or low TFAs. The proportion of foods meeting TFA limits improved from 75% in 2005-2009 to 97% in 2010-2011, particularly in the following packaged foods: croissants (25% to 100%), pies (36% to 98%), cakes (43% to 90%), and garlic spreads (33% to 100%). Most restaurant categories assessed by the TFMP had 100% of foods meeting TFA limits. Some categories had a large proportion that exceeded TFA limits: dairy-free cheeses (100%), frosting (72.0%), lard and shortening (66.7%), coffee whiteners (66.7%), and restaurant-prepared biscuits and scones (47.4%). Saturated fat amounts were significantly higher (P foods with the lowest TFAs, such as cookies, brownies and squares, cakes with pudding/mousse, dessert toppings, and lard and shortening. There has been an impressive improvement in TFA amounts in the Canadian food supply since the termination of the TFMP. However, action by the food industry is required to reduce TFAs in foods that exceed the recommended TFA limits and to minimize the use of saturated fats in replacing TFAs during reformulation. © 2014 American

The influence of food supply on the response of Olympia oyster larvae to ocean acidification

Directory of Open Access Journals (Sweden)

A. Hettinger

2013-10-01

Full Text Available Increases in atmospheric carbon dioxide drive accompanying changes in the marine carbonate system as carbon dioxide (CO2 enters seawater and alters ocean pH (termed "ocean acidification". However, such changes do not occur in isolation, and other environmental factors have the potential to modulate the consequences of altered ocean chemistry. Given that physiological mechanisms used by organisms to confront acidification can be energetically costly, we explored the potential for food supply to influence the response of Olympia oyster (Ostrea lurida larvae to ocean acidification. In laboratory experiments, we reared oyster larvae under a factorial combination of pCO2 and food level. Elevated pCO2 had negative effects on larval growth, total dry weight, and metamorphic success, but high food availability partially offset these influences. The combination of elevated pCO2 and low food availability led to the greatest reduction in larval performance. However, the effects of food and pCO2 interacted additively rather than synergistically, indicating that they operated independently. Despite the potential for abundant resources to counteract the consequences of ocean acidification, impacts were never completely negated, suggesting that even under conditions of enhanced primary production and elevated food availability, impacts of ocean acidification may still accrue in some consumers.

Traditional Agroforestry Systems and Food Supply under the Food Sovereignty Approach

Directory of Open Access Journals (Sweden)

Mariana Yazzur Hernández

2017-12-01

Full Text Available Intensive production systems have damaged many natural ecosystems and have altered their capacity to provide ecosystem services such as climate regulation, soil fertility, and vector-borne disease control. Therefore, these agroecosystems are unsustainable and poorly resilient. However, traditional agroforestry systems (TAS contribute to the conservation of biodiversity and to the provision of inputs for the maintenance of local populations. The objective of this study was to evaluate the contribution of the TAS in the food supply under the food sovereignty (FSv approach in three different ethnic groups. The study was conducted in three communities of different origin in the State of Campeche, one Maya Tseltal-Chol, the other Mestizo, and the third Yucatec Mayan. The theoretical-methodological framework of this research was based on agroecology. Ethnographic methods and participatory research activities were carried out to describe and analyze the factors that strengthen FSv using five indicators. Our results present a description and analysis of resource access, current production models, patterns of consumption and food security, commercialization and participation in decision-making of these communities. Traditional agroecological management practices are still preserved and native species are still being cultivated. Farmers obtain about 55% of their food from TAS. The consumption of food is influenced by the culture, the purchasing power linked to economic activities and government support. TAS have played a strategic role for the survival of families but to ensure their contribution to FSv, it is necessary to articulate the actions of the sectors that share the same objective and encourage the active participation of communities in agricultural policies.
Efficiency and Integration in the Food Supply Chain

Full Text Available Due to the nature of the food supply chain, an increase of the integration's degree in the chain may be an important aspect in the context of increasing the efficiency of agri-food companies. Therefore, exploring the relationships among these variables was found as an important research area and adopted as the goal of the paper. The paper is focused mainly on the theoretical background showing the relationship between integration and performance. A description of the theoretical and methodological aspects of performance measurement and its extension (including the integration aspect was also made within the framework of the paper.For an empirical illustration of the analyzed relationships two steps were made. Firstly, the integration's degree in the food chain was measured. Secondly, the efficiency of the companies from the cereals processing industry in Europe was assessed. The SFA models (e.g. Translog and Cobb-Douglas functional form were used for assessment of efficiency. By using stochastic method (e.g. the SFA, Stochastic Frontier Analysis, one may show the influence of external variable (the integration in the supply chain on the efficiency performance of enterprises. Efficiency of economic entities is not an unambiguous term. There are several different concepts of efficiency, its measurement and expressions. Within the framework of efficiency, many terms of similar meaning may be applied. However, these concepts are not identical. The actual concept of efficiency is derived from the structure of the production function, therefore it is conditioned by changes in the productivity of production factors and their remuneration and refers to the allocation of production factors in the most technically efficient way.

Levels and sources of fat in the U.S. food supply.

Raper, N R; Marston, R M

1986-01-01

The amount of fat in the U.S. food supply increased one-third between 1909-13 and 1984, from 124 grams to 166 grams per capita per day. Also, the proportion of food energy provided by fat increased from 32 to 43 percent. The gain in fat in the food supply was due to an increase in fat from vegetable sources. The share of fat from vegetable sources increased from 17 to 42 percent between 1909-13 and 1984. Although animal fats provided the largest share of fat, their proportionate contribution declined from 83 to 58 percent between 1909-13 and 1984. Three food groups--fats and oils; meat, poultry, and fish; and dairy products--provided about 90 percent of the fat in the food supply throughout the past 75 years. However, the shares of fat provided by these groups changed. The share from the fats and oils group increased from 37 to 44 percent between 1909-13 and 1984, while the share from the meat, poultry, and fish group declined from 37 to 34 percent, and the share from the dairy products group declined from 15 to 12 percent. Fat from the fats and oils group increased 59 percent between 1909-13 and 1984. Most of the gain in fat from this group was due to increased use of edible oils. Margarine replaced much of the butter and shortening replaced much of the lard as sources of fat. Fat from the meat, poultry, and fish group increased 24 percent between 1909-13 and 1984. Pork accounted for the largest proportion of fat from this group and beef ranked second. The share of fat from poultry, although much smaller than either pork or beef, almost tripled. Fat from dairy products was about the same in 1984 as in 1909-13. Cheese was the leading source of fat from dairy products by 1984. Until recent years, whole milk was the leading source, although its share declined substantially after the late 1950's. Despite their low fat content, the share of fat from skim and lowfat milks increased as use increased, particularly in the past 25 years. The proportion of fat provided by

Bernstad, Anna Karin; Cánovas, Alba; Valle, Rogerio

2017-01-01

In recent years, increased light has been shed on the large amounts of food wasted along the food supply chain (FSC). As lifecycle assessments (LCAs) are commonly used for estimations of environmental impacts from food production, it is relevant to investigate and discuss how such wastage is reflected in foodstuff LCAs. The objective of the present paper is to review a larger set of LCAs of foodstuff in order to (1) investigate if and how wastage along the FSC is addressed and (2) explore the importance of including wastage accumulated along the FSC in terms of environmental impacts. Twenty-eight LCA case studies and two review papers, focusing on tomatoes, were reviewed and greenhouse gas (GHG) emissions chosen as indicator for the second objective. Only one third of the studies consider wastage at some part of the supply chain, in many cases in an inconsistent manner, and only in nine cases were GHG emissions from wastage included in overall systems GHG emissions. In these, wastage accounts for between 2 and 33% of total contribution to climate change. Omitting wastage when conducting LCA of foodstuff could result in underestimations of environmental impacts. Occurrence of wastage along all phases of the supply chain should be acknowledged in order to estimate environmental benefits from prevention and to identify areas where strategies with the aim of reducing wastage could be most efficient.

Vibrio parahaemolyticus can accumulate and grow in oysters stored without refrigeration, representing a potential food safety risk. High temperatures during oyster storage can lead to an increase in total viable bacteria counts, decreasing product shelf life. Therefore, a predictive tool that allows the estimation of both V. parahaemolyticus populations and total viable bacteria counts in parallel is needed. A stochastic model was developed to quantitatively assess the populations of V. parahaemolyticus and total viable bacteria in Pacific oysters for six different supply chain scenarios. The stochastic model encompassed operations from oyster farms through consumers and was built using risk analysis software. Probabilistic distributions and predictions for the percentage of Pacific oysters containing V. parahaemolyticus and high levels of viable bacteria at the point of consumption were generated for each simulated scenario. This tool can provide valuable information about V. parahaemolyticus exposure and potential control measures and can help oyster companies and regulatory agencies evaluate the impact of product quality and safety during cold chain management. If coupled with suitable monitoring systems, such models could enable preemptive action to be taken to counteract unfavorable supply chain conditions.

A number of recommendations for policy and program interventions to limit excess free sugar consumption have emerged, however there are a lack of data describing the amounts and types of sugar in foods. This study presents an assessment of sugar in Canadian prepackaged foods including: (a) the first systematic calculation of free sugar contents; (b) a comprehensive assessment of total sugar and free sugar levels; and (c) sweetener and free sugar ingredient use, using the University of Toronto’s Food Label Information Program (FLIP) database 2013 (n = 15,342). Food groups with the highest proportion of foods containing free sugar ingredients also had the highest median total sugar and free sugar contents (per 100 g/mL): desserts (94%, 15 g, and 12 g), sugars and sweets (91%, 50 g, and 50 g), and bakery products (83%, 16 g, and 14 g, proportion with free sugar ingredients, median total sugar and free sugar content in Canadian foods, respectively). Free sugar accounted for 64% of total sugar content. Eight of 17 food groups had ≥75% of the total sugar derived from free sugar. Free sugar contributed 20% of calories overall in prepackaged foods and beverages, with the highest at 70% in beverages. These data can be used to inform interventions aimed at limiting free sugar consumption. PMID:27657125

Quality Risk Evaluation of the Food Supply Chain Using a Fuzzy Comprehensive Evaluation Model and Failure Mode, Effects, and Criticality Analysis

Directory of Open Access Journals (Sweden)

Libiao Bai

2018-01-01

Full Text Available Evaluating the quality risk level in the food supply chain can reduce quality information asymmetry and food quality incidents and promote nationally integrated regulations for food quality. In order to evaluate it, a quality risk evaluation indicator system for the food supply chain is constructed based on an extensive literature review in this paper. Furthermore, a mathematical model based on the fuzzy comprehensive evaluation model (FCEM and failure mode, effects, and criticality analysis (FMECA for evaluating the quality risk level in the food supply chain is developed. A computational experiment aimed at verifying the effectiveness and feasibility of this proposed model is conducted on the basis of a questionnaire survey. The results suggest that this model can be used as a general guideline to assess the quality risk level in the food supply chain and achieve the most important objective of providing a reference for the public and private sectors when making decisions on food quality management.

All entities of the food supply chain should be responsible for counteracting food waste, therefore a need arises for joint initiatives in this area. To reduce food waste, businesses should be supported with a number of procedures for the efficient use of food for social purposes that shall be consistent with the law in force. Although they can bring about some losses, the following factors neither pose a threat to human health nor affect the donation of food for social purposes: wrong labelling of packages, food product wrong weight, close-to-end expiration date as well as mechanical damage to bulk packages. The purpose of this study is to identify such points at each of the four stages of the food supply chain (primary production, processing, distribution, sale) where food losses can be prevented by donating food to those who need it. A total of 15 Recovery Points were identified at the above mentioned four stages of the food supply chain. Food recovered there is safe to human health, so it can be donated for social purposes.

2016-11-15

Research on loss & waste of food meant for human consumption (FLW) and its environmental impact typically focuses on a single or small number of commodities in a specific location and point in time. However, it is unclear how trends in global FLW and potential for climate impact have evolved. Here, by utilising the Food and Agriculture Organization's food balance sheet data, we expand upon existing literature. Firstly, we provide a differentiated (by commodity, country and supply chain stage) bottom-up approach; secondly, we conduct a 50-year longitudinal analysis of global FLW and its production-phase greenhouse gas (GHG) emissions; and thirdly, we trace food wastage and its associated emissions through the entire food supply chain. Between 1961 and 2011 the annual amount of FLW by mass grew a factor of three - from 540Mt to 1.6Gt; associated production-phase (GHG) emissions more than tripled (from 680Mt to 2.2Gt CO2e). A 44% increase in global average per capita FLW emissions was also identified - from 225kg CO2e in 1961 to 323kg CO2e in 2011. The regional weighting within this global average changing markedly over time; in 1961 developed countries accounted for 48% of FLW and less than a quarter (24%) in 2011. The largest increases in FLW-associated GHG emissions were from developing economies, specifically China and Latin America - primarily from increasing losses in fruit and vegetables. Over the period examined, cumulatively such emissions added almost 68Gt CO2e to the atmospheric GHG stock; an amount the rough equivalent of two years of emissions from all anthropogenic sources at present rates. Building up from the most granular data available, this study highlights the growth in the climate burden of FLW emissions, and thus the need to improve efficiency in food supply chains to mitigate future emissions.

Full Text Available Abstract Background In Finland, all men are liable to military service and a clear majority completes service. The increasing prevalence of obesity also among soldiers concerns conscripts’ food choices. Conscripts are served nutritionally planned regular main meals but individual choices take place in free-time eating. This study assesses the effects in conscripts’ eating habits in an intervention targeting the supply of healthy foods available in the military setting. Methods Participants were 604 18-21-year old male conscripts of whom 242 belonged to Control Group and 362 to Intervention Group. Participants of Control Group were historical controls performing military service one year before Intervention Group. The intervention targeted selection, placement, and attractiveness of healthy foods in garrison refectories and soldier’s home cafeterias, the two main food providers in the military. Dietary intake data was collected by self-administered questionnaire at three time points: before/beginning of military service (T0, 8 weeks (T1 and 6 months (T2 of military service. Outcome measures were food consumption frequencies and four dietary indexes (Cereal Index, Fruit and Vegetable Index, Fat Index and Sugar Index developed to characterize the diet. Changes between study groups in outcome variables and in time were analysed by repeated-measures analysis of covariance. Results Significant (p Conclusions In the military setting, healthier food choices can be promoted by intervening on the main food environments by improving the supply of healthy foods. However, impacting on conscripts’ individual selection as fruit and vegetable consumption is more challenging.
Systemic Analysis of Food Supply and Distribution Systems in City-Region Systems—An Examination of FAO’s Policy Guidelines towards Sustainable Agri-Food Systems

2016-12-01

Full Text Available The world is continuously transforming to supply growing cities and urbanization processes are still driving important changes in our current food systems. Future sustainability constraints are emphasizing that Food Supply and Distribution Systems (FSDS are deeply embedded in city-region systems with specific technical and socio-ecological characteristics. This paper aims to provide a systemic understanding on FSDS focusing the integration of urban and rural structures considering the system biophysical boundaries and societal targets. A qualitative framework model, based on the Food and Agriculture Organization of the United Nations (FAO’s FSDS literature, has been developed by using Systems Thinking (ST and System Dynamics (SD approaches. The model analysis suggested that to increase sustainability and resilience of food systems large emphasis has to be maintained on: (i estimation of local territorial carrying capacities; (ii land use planning to enhance connections among rural supplies and city needs; (iii city policies, to regulate emergent market size and local scale of production; (iv technological efficiency at farm, distribution and market levels; (v urban, peri-urban and rural functional linkages that considers social metabolic balances; (vi rural development as a core point for building sustainable food systems and counteracting the urbanization growth. These key areas are relevant to test new paths of cities-regions reconfiguration towards the transition to resilient agri-food systems.
Future agriculture and food supply chain - not even doomsday preppers got it right

Directory of Open Access Journals (Sweden)

Ivan Stefanic

2017-11-01

Full Text Available Future agriculture and food supply chain is one of the pillars of human survival and prosperity in the long run. The planet’s ecosystem is very fragile and influenced by a large array of very diverse natural and human factors which are frequently interdependent. Regardless of root cause, climate change, pollution and depletion of non-renewable resources and several other unfavorable processes are in place. We can argue that the increase of the average temperature is just a part of a long-term natural cycle and not the consequence of human negligence and pollution, but in the end, it doesn’t matter. The ecosystem is changed and agricultural plants might not survive the change and adopt in time. Relevant and fairly reliable indicators are available, but it seems that nobody is paying attention to those staggering numbers and trends. Doomsday preppers are well known to be a rather suspicious and concerned group of people about the reliability of future food supply chain. But even they somehow assume that agricultural production will go on, and the only problems that could occur are short run disruptions in distribution. The main challenge for future agriculture and food supply chain is to produce more food with considerably less resources in a sustainable manner for a rapidly growing population, preferably even reducing current levels of pollution. Securing future agriculture and food supply chain is a complex task which requires not only new technologies but a paradigm shift in the current technological and economic system. Possibly the most important change is the change in current agricultural practices and agricultural education. Reliability of the food system is heavily dependent on mineral oil and significant amount of transportation. Moreover, global agriculture is extremely centralized and profit oriented. Intense push of GMOs into standard agricultural practice lead to severe reduction of biodiversity in agriculture. Once upon a time

Full Text Available This article considers the problem of food supply to the Eastern front in the winter of 1917 during World War I. In the conditions of the food supply crisis the military authorities managed to avoid the famine in the army. The Front Command and the Supreme Command took some measures to resolve this problem. Attracting extra workers for harvesting, clarity of the resources allocation, calculations of the government funds allocation- all these actions bolstered the army's efforts on the home front. A considerable role in this work was played by Emperor Nicholas II, who timely and positively reacted to the suggestions of the military commanders on the issue. Overall, the Russian military command coped with this problem in the conditions of the general crisis of supplies.

Reducing food waste is one of the prominent goals in the current research, which has also been set by the United Nations to achieve a more sustainable world by 2030. Given that previous studies mainly examined causes for food waste generation related to consumers, e.g., expectations regarding quality or uncertainties about edibility, this review aims at providing an overview on losses in the food industry, as well as on natural mechanisms by which impeccable food items are converted into an undesired state. For this, scientific literature was reviewed based on a keyword search, and information not covered was gathered by conducting expert interviews with representatives from 13 German food processing companies. From the available literature, three main areas of food waste generation were identified and discussed: product deterioration and spoilage during logistical operations, by-products from food processing, and consumer perception of quality and safety. In addition, expert interviews revealed causes for food waste in the processing sector, which were categorised as follows: losses resulting from processing operations and quality assurance, and products not fulfilling quality demands from trade. The interviewees explained a number of strategies to minimise food losses, starting with alternative tradeways for second choice items, and ending with emergency power supplies to compensate for power blackouts. It became clear that the concepts are not universally applicable for each company, but the overview provided in the present study may support researchers in finding appropriate solutions for individual cases.

The question on how to evaluate a company's green practice has recently become a key strategic consideration for the food service supply chain management. This paper proposed a novel hybrid model that combines a fuzzy Decision Making Trial And Evaluation Laboratory(DEMATEL) and Analysis Network Process(ANP) methods, which developed the green restaurant criteria and demonstrated the complicated relations among various criteria to help the food service operation to better analyze the real-world situation and determine the different weight value of the criteria .The analysis of the evaluation of green practices will help the food service operation to be clear about the key measures of green practice to improve supply chain management.

Spatially diverse trends in population growth, climate change, industrialization, urbanization and economic development are expected to change future food supply and demand. These changes may affect the suitability of land for food production, implying elevated risks especially for resource constrained, food-importing countries. We present the evolution of biophysical redundancy for agricultural production at country level, from 1992 to 2012. Biophysical redundancy, defined as unused biotic and abiotic environmental resources, is represented by the potential food production of 'spare land', available water resources (i.e., not already used for human activities), as well as production increases through yield gap closure on cultivated areas and potential agricultural areas. In 2012, the biophysical redundancy of 75 (48) countries, mainly in North Africa, Western Europe, the Middle East and Asia, was insufficient to produce the caloric nutritional needs for at least 50% (25%) of their population during a year. Biophysical redundancy has decreased in the last two decades in 102 out of 155 countries, 11 of these went from high to limited redundancy, and nine of these from limited to very low redundancy. Although the variability of the drivers of change across different countries is high, improvements in yield and population growth have a clear impact on the decreases of redundancy towards the very low redundancy category. We took a more detailed look at countries classified as 'Low Income Economies (LIEs)' since they are particularly vulnerable to domestic or external food supply changes, due to their limited capacity to offset for food supply decreases with higher purchasing power on the international market. Currently, nine LIEs have limited or very low biophysical redundancy. Many of these showed a decrease in redundancy over the last two decades, which is not always linked with improvements in per capita food availability.

The Influence on Population Weight Gain and Obesity of the Macronutrient Composition and Energy Density of the Food Supply.

Science.gov (United States)

Crino, Michelle; Sacks, Gary; Vandevijvere, Stefanie; Swinburn, Boyd; Neal, Bruce

2015-03-01

Rates of overweight and obesity have increased dramatically in all regions of the world over the last few decades. Almost all of the world's population now has ubiquitous access to low-cost, but highly-processed, energy-dense, nutrient-poor food products. These changes in the food supply, rather than decreases in physical activity, are most likely the primary driver of population weight gain and obesity. To-date, the majority of prevention efforts focus on personalised approaches targeting individuals. Population-wide food supply interventions addressing sodium and trans fat reduction have proven highly effective and comparable efforts are now required to target obesity. The evidence suggests that strategies focusing upon reducing the energy density and portion size of foods will be more effective than those targeting specific macronutrients. Government leadership, clearly specified targets, accountability and transparency will be the key to achieving the food supply changes required to address the global obesity epidemic.
Listeria monocytogenes cross-contamination of cheese: risk throughout the food supply chain.

Science.gov (United States)

Sauders, B D; D'Amico, D J

2016-10-01

Listeria monocytogenes has been the most common microbial cause of cheese-related recalls in both the United States and Canada in recent years. Since L. monocytogenes is inactivated by pasteurization, the majority of these cases have been linked to environmental and cross-contamination of fresh-soft, soft-ripened, and semi-soft cheeses. Cross-contamination of foods with L. monocytogenes is a continuous risk throughout the food supply chain and presents unique challenges for subsequent illness and outbreak investigations. Reports on outbreaks of listeriosis attributed to cross-contamination downstream from primary processing help highlight the critical role of epidemiological investigation coupled with coordinated molecular subtyping and surveillance in the recognition and investigation of complex foodborne outbreaks. Despite their complexity, environmental sampling throughout the supply chain coupled with improved genotyping approaches and concomitant analysis of foodborne illness epidemiological exposure data are needed to help resolve these and similar cases more rapidly and with greater confidence.

Estimating the global prevalence of zinc deficiency: results based on zinc availability in national food supplies and the prevalence of stunting.

Directory of Open Access Journals (Sweden)

K Ryan Wessells

Full Text Available BACKGROUND: Adequate zinc nutrition is essential for adequate growth, immunocompetence and neurobehavioral development, but limited information on population zinc status hinders the expansion of interventions to control zinc deficiency. The present analyses were conducted to: (1 estimate the country-specific prevalence of inadequate zinc intake; and (2 investigate relationships between country-specific estimated prevalence of dietary zinc inadequacy and dietary patterns and stunting prevalence. METHODOLOGY AND PRINCIPAL FINDINGS: National food balance sheet data were obtained from the Food and Agriculture Organization of the United Nations. Country-specific estimated prevalence of inadequate zinc intake were calculated based on the estimated absorbable zinc content of the national food supply, International Zinc Nutrition Consultative Group estimated physiological requirements for absorbed zinc, and demographic data obtained from United Nations estimates. Stunting data were obtained from a recent systematic analysis based on World Health Organization growth standards. An estimated 17.3% of the world's population is at risk of inadequate zinc intake. Country-specific estimated prevalence of inadequate zinc intake was negatively correlated with the total energy and zinc contents of the national food supply and the percent of zinc obtained from animal source foods, and positively correlated with the phytate: zinc molar ratio of the food supply. The estimated prevalence of inadequate zinc intake was correlated with the prevalence of stunting (low height-for-age in children under five years of age (r = 0.48, P<0.001. CONCLUSIONS AND SIGNIFICANCE: These results, which indicate that inadequate dietary zinc intake may be fairly common, particularly in Sub-Saharan Africa and South Asia, allow inter-country comparisons regarding the relative likelihood of zinc deficiency as a public health problem. Data from these analyses should be used to determine

Penney, R. W.; McKenzie, C. H.; Mills, T. J.

2001-07-01

Temporal variability in the quantity, organic content, and phytoplankton composition of the particulate food supply available to a cultured mussel population was assessed for a 3-year period in a small inlet of Notre Dame Bay, Newfoundland, Canada. The study site had a restricted flushing rate estimated at 1-2·75 times wk -1for a complete water exchange. The quantity of both total (TPM) and organic (POM) seston varied temporally from 0·7-23·7 mg l -1and 0·05-1·97 mg l -1respectively during the 3-year sampling period. TPM typically remained relatively high (>10 mg l -1) through the winter and spring period. Most of the seasonal variation in total seston was due to seasonal variability in the PIM component. Both PIM and POM concentrations were seasonally lowest during summer. The organic fraction of the seston (POM/TPM ratio) was seasonally low in winter and increased steadily through spring and summer to reach its maximum in the autumn. The living phytoplankton component of the seston was typically dominated, both numerically and in biomass, by a variety of diatom and autotrophic nanoflagellate species in the 2- 20-μm diameter size range. Discrete diatom population blooms occurred in the autumn of all three years and largely consisted of a single species, Skeletonema costatum. Phytoplankton:detritus ratios were significantly lower during winter. Total phytoplankton biomass levels were seasonally low during winter and summer and were associated with seasonal variation in diatom biomass. We conducted modelling simulations of relationships among seston organic food levels, their temporal variability, tidal flushing rates, cultured mussel biomass and production indices, and estimates of mussel maintenance ration requirements to predict the adequacy of northern inlets to sustain commercial-scale mussel farm development. We conclude from these simulations that small, semi-enclosed, northern inlets likely frequently experience periods when naturally occurring organic

Energy is life. Without it there is no water, there is no nutrition. Man's ability to live, grow, produce wealth is closely linked to the energy availability and use. Fire has been the first energy conversion technology; since that moment, the link between energy and progress has been indissoluble. Nowadays, a much greater energy input into the food supply chain has made a much higher food production possible. This might have an impact on the water availability. Algae are a promising solution for the energy-food-water nexus.

Dietary fiber (DF) contributes to the energy value of foods and including it in the calculation of total food energy has been recommended for food composition databases. The present study aimed to investigate the impact of including energy provided by the DF fermentation in the calculation of food energy. Total energy values of 1753 foods from the Brazilian Food Composition Database were calculated with or without the inclusion of DF energy. The energy values were compared, through the use of percentage difference (D%), in individual foods and in daily menus. Appreciable energy D% (⩾10) was observed in 321 foods, mainly in the group of vegetables, legumes and fruits. However, in the Brazilian typical menus containing foods from all groups, only D%foods, when individually considered. Copyright © 2015 Elsevier Ltd. All rights reserved.

With approximately 1.3 billion tonnes of food wasted per annum, food supply chain wastes (FSCWs) may be viewed as the contemporary Periodic Table of biobased feedstock chemicals (platform molecules) and functional materials. Herein, the global drivers and case for food waste valorisation within the context of global sustainability, sustainable development goals and the bioeconomy are discussed. The emerging potential of high value added chemicals from certain tropical FSCW is considered as these are grown in three major geographical areas: Brazil, India and China, and likely to increase in volume. FSCW in the context of biorefineries is discussed and two case studies are reported, namely: waste potato, and; orange peel waste. Interestingly, both waste feedstocks, like many others, produce proteins and with the global demand for vegetable proteins on the rise then proteins from FSCW may become a dominant area.

Full Text Available The objective of this paper is to offer qualitative and quantitative insights on the perceptions of the actors in the EU food supply chain on a broad spectrum of topics that characterise its operation and conduct, highlighting also potential differences in North and South European countries. Issues explored pertained to actors’ relations with up- and downstream partners, the future dynamic and challenges of the food sector, the influence of policy intervention and attitudes towards genetically modified products (GMPs and organic production. For this purpose, a total of 34 food supply chain actors in Denmark and Greece were interviewed using a semi-structured interview process. A comparative analysis of the interviews pinpointed many similarities in the behaviour and the perceptions of the Greek and Danish farmers, cooperatives, processors and retailers alike. Still, while it is evident that companies and farmers of both countries struggle with a lot of the same problems, several differences in perceptions are also identified. These refer mainly to attitudes towards mergers and acquisitions, innovations, GMPs and the effects and limitations of EU policy intervention.

A systematic review was used to show the potential of Value Stream Mapping (VSM) not only to identify and reduce food losses and wastes, but also as a way to establish links with nutrient retention in supply chains. The review compiled literature from 24 studies that applied VSM in the agri-food industry. Primary production, processing, storage, food service and/or consumption were identified as susceptible hotspots for losses and wastes. Results further revealed discarding and nutrient loss, most especially at the processing level, as the main forms of loss/waste in food, which were adapted to four out of seven lean manufacturing wastes (i.e. defect, unnecessary inventory, overproduction and inappropriate processing). This paper presents the state of the art of applying lean manufacturing practices in the agri-food industry by identifying lead time as the most applicable performance indicator. VSM was also found to be compatible with other lean tools such as Just-In-Time and 5S which are continuous improvement strategies, as well as simulation modelling that enhances adoption. In order to ensure successful application of lean practices aimed at minimizing food or nutrient losses and wastes, multi-stakeholder collaboration along the entire food supply chain is indispensable.

Analysis of Total Food Intake and Composition of Individual's ...

Science.gov (United States)

EPA released the final report, Analysis of Total Food Intake and Composition of Individual’s Diet Based on USDA’s 1994-1996, 98 Continuing Survey of Food Intakes by Individuals (CSFII). The consumption of food by the general population is a significant route of potential exposure to hazardous substances that are present in the environment. For this reason, a thorough analysis of the dietary habits of the American public would aid in the identification of potential exposure pathways. To that end, the EPA developed per capita food intake rates for various food items and food categories using databases developed by the United States Department of Agriculture (USDA). These intake rates were incorporated into EPA's 1997 Exposure Factors Handbook. Since that time, EPA has recommended that the food intake study be updated and expanded to include a more comprehensive analysis of food intake. That analysis is presented in this document. The purpose of this study is to characterize the consumption of food by the people of the United States.

Full Text Available The research is devoted to the problems of food supply of the population of the region. Subject matter of the research is the relations developed in the conditions of economic reforms in the field of agrarian land use in the Republic of Bashkortostan. Purpose of the work is to develop recommendations on improvement of a situation of the food self-sufficiency and effective land use in Bashkortostan. The research is based on the dialectic approach and economic-mathematical method of the research. The results of the research testify the need of revision of such land features as an indispensability and not susceptibility to obsolescence in the conditions of further growth and development of scientific and technical progress to prevent a lag between our country and developed foreign countries in the theory of rural economics and practice of the food supply. At the differentiation of subsidies for 1 liter of milk and on 1 head of uterine livestock of breeding cattle (on 1 cow, an ewe, a goat as a correcting indicator, it is expedient to use the cadastral cost of the farmland as an integrated indicator reflecting fertility of arable and fodder grounds, an spareness, rockiness, a slope corner, transport availability or remoteness. Results of the research are applicable in the scientific and educational sphere, connected with the rural economics theory, and also in state bodies agriculture at the distribution of subsidies between market participants. Land is replaceable and worn-out means of production in agriculture, and also a basis for the enterprise placement. Ignoring of the remoteness of lands, the soil qualities, and technological properties leads to the state regulation of agriculture without including the nature efficiency of agrarian landscapes.

The aim of this study was to assess the evolution of food supply (apart from school catering) between school years 2004/2005 and 2009/2010, in middle- and high-schools from the Aquitaine region (southwest France), in order to evaluate the impact of actions conducted within the framework and the program Nutrition, Prevention and Health of children and adolescents in Aquitaine (southwest France). Two surveys were carried out among all middle- and high-schools of the Aquitaine region in 2004/2005 (n=536) and 2009/2010 (n=539) within the framework of a regional multidisciplinary public health program "Nutrition, prevention and health of children and teenagers in Aquitaine". For both 2004/2005 and 2009/2010, data were collected using the same questionnaire and dealt with school characteristics and modalities of food supply (apart from school catering). Response rate was 84.1% in 2004/2005 and 79.6% in 2009/2010. The proportion of schools offering food to pupils (apart from school catering) significantly decreased in 5 years (from 80.1% to 50.1%, Pcatering) has also been improved: less sweet and fat food, more bread and fruits. This study shows an overall improvement of food supply apart from school catering (food sale, free food and vending machines) in middle- and high-schools from the Aquitaine region (southwest France) between 2004/2005 and 2009/2010. This improvement is related to the proportion of schools offering food (quantitative improvement), as well as to the composition of food supply (qualitative improvement). These results show an improvement of food supply (apart from school catering), suggesting that actions implemented in the framework of the program "Nutrition, prevention and health of children and adolescents in Aquitaine" may have led to these improvements.

2015-12-01

This paper presents the results of a stepwise investigation of the quantity and quality of food losses along the Swiss potato supply chain. Quantitative data were collected from field trials, from structured interviews with wholesalers, processors and retailers, and from consumer surveys in combination with a 30-day diary study. The "Swiss trade customs for potatoes" pose the basis for the qualitative evaluation of losses. The influences of technological, institutional (business and economy; legislation and policy), and social drivers on the generation of fresh potato and processed potato products losses were assessed. Losses due to quality standards driven by food safety and consumer preferences for certain aesthetic standards have been evaluated too. Across the entire potato value chain, approximately 53-55% of the initial fresh potato production and 41-46% of the initial processing potato production are finally lost. Losses between organic and non-organic supply chains differ from 2% to 5%. From the total initial fresh potato production, 15-24% gets lost during agricultural production, a further 12-24% at wholesalers, 1-3% at retailers, and 15% at private households. In comparison, 5-11% of the initial production gets lost at wholesalers, a further 14-15% during processing, 0% at retailers, and 2% at private households. Losses during agricultural production do not vary much (13-25%) between fresh and processing potatoes. Approximately half of total potato losses occur because potatoes do not meet quality standards. 25-34% of these quality-driven losses are caused by food safety reasons, and the remainder are caused by consumer preferences or suitability for storage. In total, social drivers (e.g., consumer preferences, behavior, or socio-demographical factors) are responsible for two-thirds to three-fourths of all fresh potato losses and 40-45% of all processing potato losses. Technological drivers cause circa one-third of the total processing potato losses. The

The present paper reports on a quality improvement activity examining implementation of A Better Choice Healthy Food and Drink Supply Strategy for Queensland Health Facilities (A Better Choice). A Better Choice is a policy to increase supply and promotion of healthy foods and drinks and decrease supply and promotion of energy-dense, nutrient-poor choices in all food supply areas including food outlets, staff dining rooms, vending machines, tea trolleys, coffee carts, leased premises, catering, fundraising, promotion and advertising. An online survey targeted 278 facility managers to collect self-reported quantitative and qualitative data. Telephone interviews were sought concurrently with the twenty-five A Better Choice district contact officers to gather qualitative information. Public sector-owned and -operated health facilities in Queensland, Australia. One hundred and thirty-four facility managers and twenty-four district contact officers participated with response rates of 48.2% and 96.0%, respectively. Of facility managers, 78.4% reported implementation of more than half of the A Better Choice requirements including 24.6% who reported full strategy implementation. Reported implementation was highest in food outlets, staff dining rooms, tea trolleys, coffee carts, internal catering and drink vending machines. Reported implementation was more problematic in snack vending machines, external catering, leased premises and fundraising. Despite methodological challenges, the study suggests that policy approaches to improve the food and drink supply can be implemented successfully in public-sector health facilities, although results can be limited in some areas. A Better Choice may provide a model for improving food supply in other health and workplace settings.
Reducing Added Sugars in the Food Supply Through a Cap-and-Trade Approach

Lewis, Kristina

2014-01-01

Objectives. We estimated the effect of a simulated cap-and-trade policy to reduce added sugar in the food supply. Methods. Using nationally representative data on added-sugar content and consumption, we constructed a mathematical model of a cap-and-trade policy and compared its health implications to those of proposals to tax sugar sweetened beverages or added sugars. Results. Capping added-sugar emissions into the food supply by food manufacturers at a rate of 1% per year would be expected to reduce the prevalence of obesity by 1.7 percentage points (95% confidence interval [CI] = 0.9, 2.4; a 4.6% decline) and the incidence of type 2 diabetes by 21.7 cases per 100 000 people (95% CI = 12.9, 30.6; a 4.2% decline) over 20 years, averting approximately $9.7 billion in health care spending. Racial and ethnic minorities would be expected to experience the largest declines. By comparison, equivalent price penalties through excise taxes would be expected to generate smaller health benefits. Conclusions. A cap-and-trade policy to reduce added-sugar intake may reduce obesity and type 2 diabetes to a greater extent than currently-proposed excise taxes. PMID:25365146

The Institute of Food Technologists held Traceability Research Summits on July 14, August 22, and November 1, 2011, to address how to meet the growing requirement for agriculture and food traceability. Each meeting had a group of about 50 individuals who came from food companies, trade associations, local, state, and federal governments, 3rd-party traceability solution providers, not-for-profit corporations, consultants, and consumer groups. They discussed and deliberated the objectives of traceability and the means to develop product tracing in the food system. A total of 70 people participated in the 3 summits. These individuals were invited to participate in a small workgroup responsible for considering the details related to product tracing and presenting draft concepts to the larger group on November 1, 2011, in Chicago. During this meeting, the larger assembly further refined the concepts and came to an agreement on the basic principles and overall design of the desired approach to traceability. © 2013 Institute of Food Technologists®

The Seine watershed has long been the food-supplying hinterland of Paris, providing most of the animal and vegetal protein consumed in the city. Nowadays, the shift from manure-based to synthetic nitrogen fertilisation, has made possible a strong land specialisation of agriculture in the Seine watershed: it still provides most of the cereal consumed by the Paris agglomeration, but exports 80% of its huge cereal production. On the other hand the meat and milk supply originates mainly from regions in the North and West of France, specialised in animal farming and importing about 30% of their feed from South America. As it works today, this system is responsible for a severe nitrate contamination of surface and groundwater resources. Herein two scenarios of re-localising Paris's food supply are explored, based on organic farming and local provision of animal feed. We show that for the Seine watershed it is technically possible to design an agricultural system able to provide all the plant- and animal-based food required by the population, to deliver sub-root water meeting the drinking water standards and still to export a significant proportion of its production to areas less suitable for cereal cultivation. Decreasing the share of animal products in the human diet has a strong impact on the nitrogen imprint of urban food supply.
Sustained increase in food supplies reduces broodmate aggression in black-legged kittiwakes

The amount of food ingested by chicks has often been suggested as being the main proximate factor controlling broodmate aggression in facultatively siblicidal species. Although several experiments have demonstrated that short-term food deprivation causes a temporary increase in aggression, no study has, to our knowledge, experimentally manipulated overall food supplies and considered long-term effects on chick behaviour and life history traits. We provided supplemental food to breeding pairs of black-legged kittiwakes, Rissa tridactyla, over an entire breeding season and compared the aggressive behaviour of their chicks with that of chicks of control pairs. Control A-chicks (first to hatch) showed more frequent and intense aggression than their experimental counterparts. Furthermore, the more A-chicks begged and the lower their growth rate the more aggressive they were. The consequences of increased aggression for B-chicks (second to hatch) were lower begging rate, lower growth rate and lower survival. We thus provide evidence that a sustained increase in food availability affects broodmate aggression and chick survival at the nest and we discuss the various proximate and ultimate causes involved in the evolution of broodmate aggression. ?? 2010 The Association for the Study of Animal Behaviour.

Food safety regulations in Australia and New Zealand Food Standards.

Science.gov (United States)

Ghosh, Dilip

2014-08-01

Citizens of Australia and New Zealand recognise that food security is a major global issue. Food security also affects Australia and New Zealand's status as premier food exporting nations and the health and wellbeing of the Australasian population. Australia is uniquely positioned to help build a resilient food value chain and support programs aimed at addressing existing and emerging food security challenges. The Australian food governance system is fragmented and less transparent, being largely in the hands of government and semi-governmental regulatory authorities. The high level of consumer trust in Australian food governance suggests that this may be habitual and taken for granted, arising from a lack of negative experiences of food safety. In New Zealand the Ministry of Primary Industries regulates food safety issues. To improve trade and food safety, New Zealand and Australia work together through Food Standards Australia New Zealand (FSANZ) and other co-operative agreements. Although the potential risks to the food supply are dynamic and constantly changing, the demand, requirement and supply for providing safe food remains firm. The Australasian food industry will need to continually develop its system that supports the food safety program with the help of scientific investigations that underpin the assurance of what is and is not safe. The incorporation of a comprehensive and validated food safety program is one of the total quality management systems that will ensure that all areas of potential problems are being addressed by industry. © 2014 Society of Chemical Industry.
Determinants of consumer food waste behaviour: Two routes to food waste.

Science.gov (United States)

Stancu, Violeta; Haugaard, Pernille; Lähteenmäki, Liisa

2016-01-01

Approximately one quarter of the food supplied for human consumption is wasted across the food supply chain. In the high income countries, the food waste generated at the household level represents about half of the total food waste, making this level one of the biggest contributors to food waste. Yet, there is still little evidence regarding the determinants of consumers' food waste behaviour. The present study examines the effect of psycho-social factors, food-related routines, household perceived capabilities and socio-demographic characteristics on self-reported food waste. Survey data gathered among 1062 Danish respondents measured consumers' intentions not to waste food, planning, shopping and reuse of leftovers routines, perceived capability to deal with household food-related activities, injunctive and moral norms, attitudes towards food waste, and perceived behavioural control. Results show that perceived behavioural control and routines related to shopping and reuse of leftovers are the main drivers of food waste, while planning routines contribute indirectly. In turn, the routines are related to consumers' perceived capabilities to deal with household related activities. With regard to intentional processes, injunctive norms and attitudes towards food waste have an impact while moral norms and perceived behavioural control make no significant contribution. Implications of the study for initiatives aimed at changing consumers' food waste behaviour are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.
Daphnia magna fitness during low food supply under different water temperature and brownification scenarios

Andrea Gall

2016-11-01

Full Text Available Much of our current knowledge about non-limiting dietary carbon supply for herbivorous zooplankton is based on experimental evidence and typically conducted at ~1 mg C L-1 and ~20°C. Here we ask how low supply of dietary carbon affects somatic growth, reproduction, and survival of Daphnia magna and test effects of higher water temperature (+3 °C relative to ambient and brownification (3X higher than natural water color; both predicted effects of climate change during fall cooling. We predicted that even at very low carbon supply (~5µg C L-1, higher water temperature and brownification will allow D. magna to increase its fitness. Neonates (<24 h old were incubated with lake seston for 4 weeks (October-November 2013 in experimental bottles submerged in outdoor mesocosms to explore effects of warmer and darker water. Higher temperature and brownification did not significantly affect food quality, as assessed by its fatty acid composition. Daphnia exposed to both increased temperature and brownification had highest somatic growth and were the only that reproduced, and higher temperature caused the highest Daphnia survival success. These results suggest that even under low temperature and thus lower physiological activity, low food quantity is more important than its quality for D. magna fitness.

Iodine 131 was detected in the environment and the food such as vegetables, raw milk and tap water just after the reactor accident following the East Japan Great Earthquake occurred in March 11, 2011. This article investigated status of refuge of Fukushima residents, their dietary life and food distribution from March 11 to 31 just after the accident so as to reevaluate internal exposure dose with Iodine 131. Investigation results showed most of food taken by refugees was confirmed food stock or relief supplies outside from the disaster area and suggested food contaminated with Iodine 131 was not widely consumed and distributed due to limit to send designated vegetables, restriction of tap water intake, damaged distribution facilities and closing down of retail stores. Restriction of tap water intake was only applied partly, so this might cause internal exposure dose due to tap water. (T. Tanaka)

Little is known about the practices for stocking and procuring healthy food in non-traditional food retailers (e.g., gas-marts, pharmacies). The present study aimed to: (i) compare availability of healthy food items across small food store types; and (ii) examine owner/manager perceptions and stocking practices for healthy food across store types. Descriptive analyses were conducted among corner/small grocery stores, gas-marts, pharmacies and dollar stores. Data from store inventories were used to examine availability of twelve healthy food types and an overall healthy food supply score. Interviews with managers assessed stocking practices and profitability. Small stores in Minneapolis and St. Paul, MN, USA, not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children. One hundred and nineteen small food retailers and seventy-one store managers. Availability of specific items varied across store type. Only corner/small grocery stores commonly sold fresh vegetables (63% v. 8% of gas-marts, 0% of dollar stores and 23% of pharmacies). More than half of managers stocking produce relied on cash-and-carry practices to stock fresh fruit (53%) and vegetables (55%), instead of direct store delivery. Most healthy foods were perceived by managers to have at least average profitability. Interventions to improve healthy food offerings in small stores should consider the diverse environments, stocking practices and supply mechanisms of small stores, particularly non-traditional food retailers. Improvements may require technical support, customer engagement and innovative distribution practices.

The objective of COMWEB was to develop efficient analytical, numerical and experimental methods for assessing and predicting the effects of nutrient (N, P, Si) supply on the stability and persistence of pelagic food web structure and function in coastal waters. The experimental comparative work included a geographic gradient covering Baltic, Mediterranean, and NE Atlantic waters and a NE Atlantic gradient in state of eutrophication. COMWEB has been an experimental approach to coastal eutrophication, studying effects of enhanced nutrient supply on components and flows of the entire lower pelagic food web. Flow network representations of pelagic food webs has been a framework of data reduction and flows were established by sophisticated inverse modelling. Fundamental information on physiological properties of functional key species in the pelagic food web was used to constrain flow estimations. A main conclusion derived from the flow networks was that very little energy and materials were transferred from the microbial food web to the main food chain. The lower food web could therefore be described as two parallel food chains with relatively limited interaction between heterotrophic groups. Short-term effects of nutrient perturbations were examined in mesocosms along the geographic gradient. The response was comparable in all systems, with a stronger effect on the activity and biomass of autotrophic groups than those of heterotrophic ones. Mediterranean waters showed much lower autotrophic biomass response than Baltic and NE Atlantic waters, which responded almost equally. The response of primary production was, however, more comparable. High phytoplankton lysis rate explained this low accumulation of biomass in Mediterranean waters. The study of Atlantic coastal waters of different eutrophic states revealed that the ecological response was higher in the closed nutrient perturbed mesocosms than in open systems exposed for >4 summer months (summer/autumn season).

Benthic foraminiferal analysis of 29 samples in surface sediments from the southern Oki-nawa Trough is carried out. The results indicate that benthic foraminiferal abundance decreases rapidlywith increasing water depth. Percentage frequencies of agglutinated foraminifera further confirm themodem shallow carbonate lysocline in the southern Okinawa Trough. From continental shelf edge to thebottom of Okinawa Trough, benthic foraminiferal fauna in the surface sediments can be divided into 5assemblages: (1) Continental shelf break assemblage, dominated by Cibicides pseudoungerianus, corre-sponds to subsurface water mass of the Kuroshio Current; (2) upper continental slope assemblage, domi-nated by Cassidulina carinata, Globocassidulina subglobosa, corresponds to intermediate water mass of the Kuroshio Current; (3) intermediate continental slope assemblage, dominated by Uvigerina hispi-da, corresponds to the Okinawa Trough deep water mass above the carbonate lysocline; (4) lower con-tinental slope- trough bottom assemblage, dominated by Pullenia bulloides, Epistominella exigua andCibicidoides hyalinus, corresponds to deep water mass of the Okinawa Trough; and (5) trough bottomagglutinated assemblage, dominated by Rhabdammina spp., Bathysiphon flavidus, corresponds tostrongly dissolved environment of the trough bottom. The benthic foraminiferal fauna in the southemOkinawa Trough are controlled jointly by water masses and food supply. Water temperature, oxygenconcentration and carbonate dissolution of the water masses are important controlling factors especiallyfor the continental shelf break and trough bottom assemblages. The food supply also plays an importantrole in these benthic foraminiferal assemblages along the westem slope of the Okinawa Trough. Both theabundance and the 5 assemblages of benthic foraminifera correspond well to the organic matter supplyalong the continental slope and a lateral transport of TSM (total suspended matter) and POC (particulateorganic
Global Expanded Nutrient Supply (GENuS Model: A New Method for Estimating the Global Dietary Supply of Nutrients.

Directory of Open Access Journals (Sweden)

Matthew R Smith

Full Text Available Insufficient data exist for accurate estimation of global nutrient supplies. Commonly used global datasets contain key weaknesses: 1 data with global coverage, such as the FAO food balance sheets, lack specific information about many individual foods and no information on micronutrient supplies nor heterogeneity among subnational populations, while 2 household surveys provide a closer approximation of consumption, but are often not nationally representative, do not commonly capture many foods consumed outside of the home, and only provide adequate information for a few select populations. Here, we attempt to improve upon these datasets by constructing a new model--the Global Expanded Nutrient Supply (GENuS model--to estimate nutrient availabilities for 23 individual nutrients across 225 food categories for thirty-four age-sex groups in nearly all countries. Furthermore, the model provides historical trends in dietary nutritional supplies at the national level using data from 1961-2011. We determine supplies of edible food by expanding the food balance sheet data using FAO production and trade data to increase food supply estimates from 98 to 221 food groups, and then estimate the proportion of major cereals being processed to flours to increase to 225. Next, we estimate intake among twenty-six demographic groups (ages 20+, both sexes in each country by using data taken from the Global Dietary Database, which uses nationally representative surveys to relate national averages of food consumption to individual age and sex-groups; for children and adolescents where GDD data does not yet exist, average calorie-adjusted amounts are assumed. Finally, we match food supplies with nutrient densities from regional food composition tables to estimate nutrient supplies, running Monte Carlo simulations to find the range of potential nutrient supplies provided by the diet. To validate our new method, we compare the GENuS estimates of nutrient supplies against

TFA was detected in all samples, except for four samples including one plain bread, one sponge cake, and two batter-made foods (egg roll and eggette samples. For those found to contain detectable TFA, the content ranged up to 4.7 g/100 g of food or 17.3% of total lipids. On a per 100 grams of food basis, the highest mean TFA content among the 18 food subgroups was the doughnuts/French toast subgroup (0.95 g, followed by the other pastries subgroup (0.49 g and the bread with filling/topping subgroup (0.44 g. Among the samples, the highest TFA content is from a doughnut (4.7 g/100 g, followed by two cream-filled bread with shredded coconut (1.8 and 1.4 g/100 g and a sweetheart cake (1.7 g/100 g. Only consuming one whole piece of doughnut would have reached 100% of the maximum daily TFA intake as recommended by WHO based on a 2000 kcal diet. About 78% of samples had TFA ≤0.3 g/100 g food. For the majority of the food samples available in Hong Kong, if TFA was present, C18:1 trans would possibly be the predominant one.

Human-wildlife conflicts impose considerable costs to people and wildlife worldwide. Most research focuses on proximate causes, offering limited generalizable understanding of ultimate drivers. We tested three competing hypotheses (problem individuals, regional population saturation, limited food supply) that relate to underlying processes of human-grizzly bear (Ursus arctos horribilis) conflict, using data from British Columbia, Canada, between 1960-2014. We found most support for the limited food supply hypothesis: in bear populations that feed on spawning salmon (Oncorhynchus spp.), the annual number of bears/km(2) killed due to conflicts with humans increased by an average of 20% (6-32% [95% CI]) for each 50% decrease in annual salmon biomass. Furthermore, we found that across all bear populations (with or without access to salmon), 81% of attacks on humans and 82% of conflict kills occurred after the approximate onset of hyperphagia (July 1(st)), a period of intense caloric demand. Contrary to practices by many management agencies, conflict frequency was not reduced by hunting or removal of problem individuals. Our finding that a marine resource affects terrestrial conflict suggests that evidence-based policy for reducing harm to wildlife and humans requires not only insight into ultimate drivers of conflict, but also management that spans ecosystem and jurisdictional boundaries.

Food availability is generally considered to determine breeding site selection and therefore plays an important role in hypotheses explaining the evolution of colony formation. Hypotheses trying to explain why birds join a colony usually assume that food is not limited, whereas those explaining variation in colony size suggest that food is under constraint. In this study, we investigate the composition and amount of food items not eaten by the nestlings and found in nest burrows of colonially nesting European bee-eaters (Merops apiaster). We aimed to determine whether this unconsumed food is an indicator of unlimited food supply, the result of mistakes during food transfer between parents and chicks or foraging selectivity of chicks. Therefore, we investigated the amount of dropped food for each nest in relation to reproductive performance and parameters reflecting parental quality. Our data suggest that parents carry more food to the nest than chicks can eat and, hence, food is not limited. This assumption is supported by the facts that there is a positive relationship between dropped food found in a nest and the number of fledglings, nestling age, and chick health condition and that the amount of dropped food is independent of colony size. There is variation in the amount of dropped food within colonies, suggesting that parent foraging efficiency may also be an important determinant. Pairs nesting in the center of a colony performed better than those nesting on the edge, which supports the assumption that quality differences between parents are important as well. However, dropped food cannot be used as an indicator of local food availability as (1) within-colony variation in dropped food is larger than between colony variation and, (2) the average amount of dropped food is not related to colony size.
FUNCTIONAL SHORT FOOD SUPPLY CHAINS IN THE FIELD OF ROMANIAN RURAL TOURISM. CASE STUDY: HARGHITA AND NEAMȚ COUNTIES

Full Text Available Nowadays, one cannot talk about an authentic rural tourism within a certain destination without emphasizing the local cultural heritage (cultural landscape, customs and traditions, gastronomy and so on. In the existing context, the local gastronomy is perceived as a marketing instrument efficient in differentiating the rural touristic destinations. A special place in the development of the traditional cuisine is represented by the setting up and the promotion of the short food supply chains which can be achieved by sustaining the small local producers and by putting into practice an environment-friendly traditional agriculture. Sustaining the partnerships between the owners of accommodation units and the small local agricultural producers represents an essential element in putting into practice a sustainable and qualitative rural tourism. Romania has a substantial potential as regards the enhancement of short food supply chains thanks to: the large number of semi-subsistence agricultural farms (with an area under 5 hectares, the „village-town connection” as regards the food procurement, especially from acquaintances and relatives and the carrying on of a traditional agriculture at a large scale in the rural households.The case studies emphasized in the current paper (Harghita and Neamţ Counties focus on the existence of short food supply chains, functional in the rural tourism sector under very different ways: touristic sheepfolds, trout farms, inns, authentic holiday villages, peasant guest houses etc.
China's new problems of food security revealed by the Food Equivalent Unit

Full Text Available China's food security has a great influence on the world, and has always been the top priority in China. In recent years, as the concept of food security is evolving into one of nutrition security and the importance of food diversity is increasing, research based on nutrition security and broad food systems are increasingly needed in today's China. Thus, not only grain for human consumption, but also animal foods have been integrated into the Food Equivalent, which is used to analyze China's current agriculture system and reveal the water resource distribution. The results indicated that the average animal food consumption has risen by 78.6%, and now China's daily supply of animal food per capita has reached about 50% of that in the USA and 80% of that in the South Korea. So there exist an obvious disparity in animal food supply between China and these two countries. It is impossible for the China's current agricultural system to achieve the level in the USA. Under China's current agricultural system, the consumption proportion of feed grain had surpassed the consumption of food grain, increased sharply from 33% in 1992 to 67% in 2011. However, the growth potential of total grain output is approaching an upper limit, so the continued growth of feed grain demand exerts great pressure on the China's food supply. The discordance of the spatial distribution of water resource and virtual water revealed that China's current agriculture system had a low efficiency in being able to achieve food and nutrition security. China's current "grain farming" cannot meet the demand of increasing nutrition and appropriate resource utilization. The implementation of grassland agriculture appears feasible and necessary for saving feed grain, providing a large number of high-quality animal foods and appropriate water resource utilization.
Biomineralization changes with food supply confer juvenile scallops (Argopecten purpuratus) resistance to ocean acidification, supplement to: Ramajo, L; Marba, Núria; Prado, Luis; Peron, Sophie; Lardies, Marco A; Rodriguez-Navarro, Alejandro; Vargas, C A; Lagos, Nelson A; Duarte, Carlos M (2016): Biomineralization changes with food supply confer juvenile scallops (Argopecten purpuratus) resistance to ocean acidification.

Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth phase, food supply may play a key role in the response of marine organisms to OA. We experimentally evaluated the role of food supply in modulating physiological responses and biomineralization processes in juveniles of the Chilean scallop, Argopecten purpuratus, that were exposed to control (pH 8.0) and low pH (pH 7.6) conditions using three food supply treatments (high, intermediate, and low). We found that pH and food levels had additive effects on the physiological response of the juvenile scallops. Metabolic rates, shell growth, net calcification, and ingestion rates increased significantly at low pH conditions, independent of food. These physiological responses increased significantly in organisms exposed to intermediate and high levels of food supply. Hence, food supply seems to play a major role modulating organismal response by providing the energetic means to bolster the physiological response of OA stress. On the contrary, the relative expression of chitin synthase, a functional molecule for biomineralization, increased significantly in scallops exposed to low food supply and low pH, which resulted in a thicker periostracum enriched with chitin polysaccharides. Under reduced food and low pH conditions, the adaptive organismal response was to trade-off growth for the expression of biomineralization molecules and altering of the organic composition of shell periostracum, suggesting that the future performance of these calcifiers will depend on the trajectories of both OA and food supply. Thus, incorporating a suite of traits and multiple stressors in future studies of the adaptive organismal response may provide key insights on OA impacts on marine calcifiers.

Vitamin K food composition data have historically been limited to plant-based phylloquinone (vitamin K1). The purpose of this study was to expand analysis of vitamin K to animal products and to measure phylloquinone and 10 forms of menaquinones (vitamin K2) in processed and fresh-cut pork products. Nationally representative samples of processed pork products (n = 28) were obtained through USDA's National Food and Nutrition Analysis Program, and fresh pork (six cuts; n = 5 per cut) and bacon (n = 4) were purchased from local retail outlets. All samples were analyzed by high-performance liquid chromatography (phylloquinone and menaquinone-4) and atmospheric-pressure chemical ionization-liquid chromatography-mass spectrometry (menaquinone-5 to menaquinone-13). Although low in phylloquinone (processed pork products and fresh pork cuts contained menaquinone-4, menaquinone-10, and menaquinone-11 (range: [35.1 ± 11.0]-[534 ± 89.0] μg of menaquinones per 100 g). The total menaquinone contents of processed pork products were correlated with fat contents (r = 0.935). In summary, processed and fresh-cut pork products are a rich dietary source of menaquinones that are currently unaccounted for in assessment of vitamin K in the food supply.

Mycotoxins are a group of naturally occurring toxic chemical substances, produced mainly by microscopic filamentous fungal species. Regarding potential synergisms or even mitigating effects between toxic elements, mycotoxin contamination will continue to be an area of concern for producers, manufacturers, regulatory agencies, researchers, and consumers in the future. In Serbia, recent drought and then flooding confirmed that mycotoxins are one of the foodborne hazards most susceptible to climate change. In this article, we review key aspects of mycotoxin contamination of the food supply chain and implications for public health from the Serbian perspective.

The aim of this study was to examine differences in the validity of a visual estimation method for determining patients' meal intake between various meal types and supplied food items in hospitals and to find factors influencing the validity of a visual estimation method. There are two procedures by which we obtained the information on dietary intake of the patients in these hospitals. These are both by visual assessment from the meal trays at the time of their clearing, by the attending nursing staff and by weighing conducted by researchers. The following criteria are set for the target trays: A) standard or therapeutic meals, which are monitored by a doctor, for energy and/or protein and/or sodium; B) regular, bite-sized, minced and pureed meal texture, and C) half-portion meals. Visual assessment results were tested for their validity by comparing with the corresponding results of weighing. Differences between these two methods indicated the estimated and absolute values of nutrient intake. A total of 255 (76.1%) trays were included in the analysis out of the 335 possible trays and the results indicated that the energy consumption estimates by visual or weighing procedures are not significantly different (412 ± 173 kcal, p = 0.15). However, the mean protein consumption was significantly different (16.3 ± 6.7 g/tray, p food items were significantly misestimated for energy intake (66 ± 58 kcal/tray) compared to trays with no additions (32 ± 39 kcal/tray, p food items were significantly associated with increased odds of a difference between the two methods (OR: 3.84; 95% confidence interval [CI]: 1.07-13.85). There were high correlations between the visual estimation method and the weighing method measuring patients' dietary intake for various meal types and textures, except for meals with added supplied food items. Nursing staff need to be attentive to supplied food items. Copyright © 2018 Elsevier Ltd and European Society for Clinical

Position of the American Dietetic Association: total diet approach to communicating food and nutrition information.

Science.gov (United States)

Nitzke, Susan; Freeland-Graves, Jeanne

2007-07-01

It is the position of the American Dietetic Association that the total diet or overall pattern of food eaten is the most important focus of a healthful eating style. All foods can fit within this pattern, if consumed in moderation with appropriate portion size and combined with regular physical activity. The American Dietetic Association strives to communicate healthful eating messages to the public that emphasize a balance of foods, rather than any one food or meal. Public policies that support the total diet approach include the Dietary Guidelines for Americans, MyPyramid, the DASH Diet (Dietary Approaches to Stop Hypertension), Dietary Reference Intakes, and nutrition labeling. The value of a food should be determined within the context of the total diet because classifying foods as "good" or "bad" may foster unhealthful eating behaviors. Alternative approaches may be necessary in some health conditions. Eating practices are dynamic and influenced by many factors, including taste and food preferences, weight concerns, physiology, lifestyle, time challenges, economics, environment, attitudes and beliefs, social/cultural influences, media, food technology, and food product safety. To increase the effectiveness of nutrition education in promoting sensible food choices, food and nutrition professionals should utilize appropriate behavioral theory and evidence-based strategies. A focus on moderation and proportionality in the context of a healthful lifestyle, rather than specific nutrients or foods, can help reduce consumer confusion. Proactive, empowering, and practical messages that emphasize the total diet approach promote positive lifestyle changes.

From food insufficiency towards trade dependency: a historical analysis of global food availability.

Directory of Open Access Journals (Sweden)

Miina Porkka

Full Text Available Achieving global food security is one of the major challenges of the coming decades. In order to tackle future food security challenges we must understand the past. This study presents a historical analysis of global food availability, one of the key elements of food security. By calculating national level dietary energy supply and production for nine time steps during 1965-2005 we classify countries based on their food availability, food self-sufficiency and food trade. We also look at how diets have changed during this period with regard to supply of animal based calories. Our results show that food availability has increased substantially both in absolute and relative terms. The percentage of population living in countries with sufficient food supply (>2500 kcal/cap/d has almost doubled from 33% in 1965 to 61% in 2005. The population living with critically low food supply (15% of dietary energy supply increased from 33% to over 50%. While food supply has increased globally, food self-sufficiency (domestic production>2500 kcal/cap/d has not changed remarkably. In the beginning of the study period insufficient domestic production meant insufficient food supply, but in recent years the deficit has been increasingly compensated by rising food imports. This highlights the growing importance of food trade, either for food supply in importing countries or as a source of income for exporters. Our results provide a basis for understanding past global food system dynamics which, in turn, can benefit research on future food security.
THE ROLE OF CONSUMERS IN THE TRANSITION TOWARDS A SUSTAINABLE FOOD SUPPLY. THE CASE OF GRUPPI DI ACQUISTO SOLIDALE (SOLIDARITY PURCHASING GROUPS IN ITALY

2015-10-01

Full Text Available This paper addresses the role of ethical consumers in the transition process towards a sustainable food supply. The questions that immediately come to mind are: can the consumers put changes in motion in the established food supply regime? Which are the mechanisms hindering a transition driven by consumers? In order to answer to these questions we analyse the case of Gruppi di Acquisto Solidale (Solidarity Purchasing Groups in Italy, as a support for a broader reflection to the topic. The growing dissatisfaction with the established food supply, dominated by the duopoly supermarket-global food supplier, has driven a few pioneers to search for new solutions. In the case of Italy, consumers have organized themselves into informal networks, in order to purchase quality food together from local farmers. They are motivated by the meeting of social, ethical and environmental needs (providing sustainable food and support local farmers which were not served in the beginning by incumbent firms and they operate in the social economy as community groups.
Economic performance of water storage capacity expansion for food security

SummaryContinued climate variability, population growth, and rising food prices present ongoing challenges for achieving food and water security in poor countries that lack adequate water infrastructure. Undeveloped storage infrastructure presents a special challenge in northern Afghanistan, where food security is undermined by highly variable water supplies, inefficient water allocation rules, and a damaged irrigation system due three decades of war and conflict. Little peer-reviewed research to date has analyzed the economic benefits of water storage capacity expansions as a mechanism to sustain food security over long periods of variable climate and growing food demands needed to feed growing populations. This paper develops and applies an integrated water resources management framework that analyzes impacts of storage capacity expansions for sustaining farm income and food security in the face of highly fluctuating water supplies. Findings illustrate that in Afghanistan's Balkh Basin, total farm income and food security from crop irrigation increase, but at a declining rate as water storage capacity increases from zero to an amount equal to six times the basin's long term water supply. Total farm income increases by 21%, 41%, and 42% for small, medium, and large reservoir capacity, respectively, compared to the existing irrigation system unassisted by reservoir storage capacity. Results provide a framework to target water infrastructure investments that improve food security for river basins in the world's dry regions with low existing storage capacity that face ongoing climate variability and increased demands for food security for growing populations.

To assess supply and nutritional composition of the salads offered as an entrée main course in the food courts of the shopping centers in Lima, Peru. The menus of all food franchises present in the food courts of the eleven shopping centers of Lima were reviewed. The nutritional composition of salads offered as an entrée were calculated for calories, protein content, carbohydrates, fats, cholesterol, fiber and sodium, and the adequacy of intake for a dinner (30% of a diet of 2000 kcal). Salads as entrées accounted for 4.7% of the supply, and only 7 out of 17 franchises offered at least one salad. The average cost of the salads was higher than the other dishes ($5.3 vs $4.7; p<0.001). The average calorie content was 329 kcal and 2.7 g fiber; in relation to a dinner, we found a high percentage of adequacy for protein (172.9%), cholesterol (121.0%), and low adequacy for calories (54.8%), carbohydrates (23.1%) and fiber (36.4%). The salads that are offered in food courts in the shopping centers of Lima are scarce and more expensive, have little fiber content and are high in cholesterol. Strategies should be reviewed to improve the accessibility of quality salads offered in areas where only fast food is offered.

Insights into the use of health-related information on foods are important for planning studies about the effects of such information on the consumer's understanding, purchasing, and consumption of foods, and also support further food policy decisions. We tested the use of sales data for weighting consumers' exposure to health-related labeling information in the Slovenian food supply. Food labeling data were collected from 6342 pre-packed foods available in four different food stores in Slovenia. Consumers' exposure was calculated as the percentage of available food products with particular food information in the food category. In addition, 12-month sales data were used to calculate sales weighted exposure as a percentage of sold food products with certain food information in the food category. The consumer's in-store and sales-weighted exposure to nutrition claims was 37% and 45%, respectively. Exposure to health claims was much lower (13%, 11% when sales-weighted). Health claims were mainly found in the form of general non-specific claims or function claims, while children's development and reduction of disease risk claims were present on only 0.1% and 0.2% of the investigated foods, respectively. Sales data were found very useful for establishing a reliable estimation of consumers' exposure to information provided on food labels. The high penetration of health-related information on food labels indicates that careful regulation of this area is appropriate. Further studies should focus on assessing the nutritional quality of foods labeled with nutrition and health claims, and understanding the importance of such labeling techniques for consumers' food preferences and choices.

The US is the largest producer in the world, 89% of corn production uses in domestic demands in 2012. Carbon emission and irrigated water usage in the corn farming stage are hot-spot in the meat production sectors, comprise 37% of all US corn demand. The annual capacity of the ethanol sector increases from 6.5 billion gallons to 15.3 billion gallons for the last decade. The growth of corn demand in ethanol sector makes corn supply chain shift. Most of the ethanol plants located in the Mid-west where is the top 12 corn producing states. Therefore animal feeds take more supply from the other states. The purpose of this study is to estimate environmental impacts and water scarcity associated embedded corn by the temporal and spatial corn supply chain model based on a cost minimization. We use publicly available county-level data on corn production, feed demands, aggregative carbon emission and irrigated water usage in farming state, and a water depletion index as a metric for determining water scarcity. The water stressed counties produce 23.3% of US total corn production in 2012, and the irrigated corn is 14.2%. We simulated the corn supply chain using linear programming and developed the web-based visualization tools called FoodS3 (Food Systems Supply-chain Sustainability tool, http://foods3.org).

Probability curves predicting oral food challenge test (OFC) results based on specific IgE levels are widely used to prevent serious allergic reactions. Although several confounding factors are known to affect probability curves, the main factors that affect OFC outcomes are currently unclear. We hypothesized that an increased total IgE level would reduce allergic reactivity. Medical records of 337 and 266 patients who underwent OFCs for 3.5 g boiled hen's egg white and 3.1 ml raw cow's milk, respectively, were examined retrospectively. We subdivided the patients into three groups based on total IgE levels and age by percentile (75th percentiles), and logistic regression analyses were performed on each group. Patients with higher total IgE levels were significantly less responsive. In addition, age did not significantly affect the OFC results. Therefore, total IgE levels should be taken into account when predicting OFC results based on food-specific IgE levels. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Within the Nutrition, Prevention, and Health Program for children and teenagers in Aquitaine, an experimental intervention was implemented in 2007-2008 in the middle and high schools in Aquitaine (southwest France). This intervention aimed to improve the eating habits of adolescents, combining actions to improve the food supply sold during recreational times (remove/limit fat and sugar products sold and promote the sale of fruits and bread) and health education actions to make adolescents aware of the concept of nutritional balance and steer their choice towards recommended products. The aim of this paper was to evaluate the impact of the intervention on the eating behavior of adolescents and the food supply sold during recreational times in middle and high schools in Aquitaine. A survey was conducted before and after the implementation of the intervention in seven middle and high schools that have implemented actions (intervention group) and eight middle and high schools that have not implemented actions (control group). In these schools, 1602 adolescents answered the survey before and 1050 after the intervention (samples were independent because of the anonymity of responses). The impact of the intervention on the dietary behavior of teenagers was modeled using logistic regression adjusted on potential confounding variables (sex, age, and educational status). In multivariate analyses, the intervention was associated with more frequent daily intake of breakfast (OR=2.63; 95% CI [1.89; 3.66]) and lower intake of morning snacks (OR=0.66; 95% CI [0.48; 0.90]), higher consumption of starchy foods (OR=1.77; 95% CI [1.30; 2.42]), bread at breakfast, morning snacks, and a light afternoon meal (OR=1.43; 95% CI [1.07; 1.90]), and the food supply sold at recreational times (OR=1.34 95% CI [1.01; 1.78]). These results show that the "Improving food supply in middle and high schools associated with educational support actions" project led to the sales of recommended foods

High consumption of refined carbohydrate, in particular sugar, has been identified as a possible contributory factor in greater risk of excess weight gain. In spite of data limitations, one recent paper suggests that Australian sugar consumption has decreased over the same time period that obesity has increased, a so called 'Australian Paradox'. Given the significant public health focus on nutrition, we aimed to estimate Australian sugar supply and consumption over recent decades, to determine whether these data could be used to make any conclusions about sugar's role in obesity. Foods high in sugar were identified. Data relating to sugar supply and consumption from 1988 to 2010 were obtained from multiple sources. Using these data we attempted to generate a time series estimate of sugar in Australia's food supply. Australia produces and exports sugar from sugar cane and the sugar in imported foods has received little attention. We were unable to produce a reliable and robust estimate of total sugars in the Australian diet due to data limitations and a lack of current data sources. However, available Import data showed large increases in the volume and value of imported sweetened products between 1988 and 2010 to over 30 grams of sugar per person per day. Value estimates of local production of sweetened products also show substantial increases in this period. The Australian Paradox assertion is based on incomplete data, as it excludes sugar contained in imported processed foods, which have increased markedly. A major Australian public health target is to improve the quality of the food supply, and actions have been set in terms of achieving broader environmental changes. However, evaluation of progress is hampered by lack of high quality data relating to supply and consumption. We recommend the regular collection of comprehensive food supply statistics, which include both local production and imports. This would provide an inexpensive addition to survey data and

As part of the previous French Total Diet Studies (TDS) focusing on exposure to food chemicals in the population aged 3 years and older, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) launched a specific TDS on infants to complete its overall chemical food safety programme for the general population. More than 500 chemical substances were analysed in food products consumed by children under 3 years old, including nutrients, several endocrine disruptors resulting from human activities (polychlorinated biphenyls, dioxins and furans, brominated flame retardants, perfluoroalkyl acids, pesticide residues, etc.) or migrating from food contact materials such as bisphenol A or phthalates, but also natural substances such as mycotoxins, phytoestrogens and steroids. To obtain a representative and general view of infant food consumption, food items were selected based on results of a national consumption survey conducted specifically on this population. Moreover, a specific study on food was conducted on 429 households to determine which home-cooking practices are employed to prepare food consumed by infants. Overall, the targeted chemical substances were analysed in more than 450 food samples, representing the purchase and home-cooking practices of over 5500 food products. Foods included common foods such as vegetables, fruit or cakes as well as specific infant foods such as infant formula or jarred baby food. The sampling plan covered over 80% of the total diet. Specificities in infant food consumption and habits were therefore considered to define this first infant TDS. This study, conducted on a large scale and focusing on a particularly sensitive population, will provide accurate information on the dietary exposure of children under 3 years to food chemicals, especially endocrine disruptors, and will be particularly useful for risk assessment analysis under the remit of ANSES' expert committees.

2017-10-03

Reducing food losses and waste is crucial to making our food system more efficient and sustainable. This is the first paper that quantifies the environmental impacts of food waste by distinguishing the various stages of the food value chain, 33 food categories that represent the whole food basket in Switzerland, and including food waste treatment. Environmental impacts are expressed in terms of climate change and biodiversity impacts due to water and land use. Climate change impacts of food waste are highest for fresh vegetables, due to the large amounts wasted, while the specific impact per kg is largest for beef. Biodiversity impacts are mainly caused by cocoa and coffee (16% of total) and by beef (12%). Food waste at the end of the food value chain (households and food services) causes almost 60% of the total climate impacts of food waste, because of the large quantities lost at this stage and the higher accumulated impacts per kg of product. The net environmental benefits from food waste treatment are only 5-10% of the impacts from production and supply of the wasted food. Thus, avoiding food waste should be a first-line priority, while optimizing the method of treatment is less relevant.

Objective. To assess the diagnostic significance of total IgE in foods, inhalant, and multiple allergies. Methods. Retrospective review of the laboratory records of patients who presented with clinical suspicion of food or inhalant allergy between January 2013 and December 2014. Total IgE level was defined as positive for a value >195 kU/L; and diagnosis was confirmed by the detection of specific IgE (golden standard) for at least one food or inhalant allergen and at least two allergens in multiple allergies. Results. A total of 1893 (male ratio = 0.68, mean age = 39.0 ± 19.2 years) patients were included. Total IgE had comparable sensitivity (55.8% versus 59.6%) and specificity (83.9% versus 84.4%) in food versus inhalant allergy, respectively, but a superior PPV in inhalant allergy (79.1% versus 54.4%). ROC curve analysis showed a better diagnostic value in inhalant allergies (AUC = 0.817 (95% CI = 0.796-0.837) versus 0.770 (95% CI = 0.707-0.833)). In multiple allergies, total IgE had a relatively good sensitivity (78.6%), while negative IgE testing (allergies with 91.5% certitude. Conclusion. Total IgE assay is not efficient as a diagnostic test for foods, inhalant, or multiple allergies. The best strategy should refer to specific IgE testing guided by a comprehensive atopic history.

A 2-day interactive forum was convened to discuss the current status and future implications of reducing sodium in the food supply and to identify opportunities for stakeholder collaboration. Participants included 128 stakeholders engaged in food research and development, food manufacturing and retail, restaurant and food service operations, regulatory and legislative activities, public health initiatives, healthcare, academia and scientific research, and data monitoring and surveillance. Presentation topics included scientific evidence for sodium reduction and public health policy recommendations; consumer sodium intakes, attitudes, and behaviors; food technologies and solutions for sodium reduction and sensory implications; experiences of the food and dining industries; and translation and implementation of sodium intake recommendations. Facilitated breakout sessions were conducted to allow for sharing of current practices, insights, and expertise. A well-established body of scientific research shows that there is a strong relationship between excess sodium intake and high blood pressure and other adverse health outcomes. With Americans getting >75% of their sodium from processed and restaurant food, this evidence creates mounting pressure for less sodium in the food supply. The reduction of sodium in the food supply is a complex issue that involves multiple stakeholders. The success of new technological approaches for reducing sodium will depend on product availability, health effects (both intended and unintended), research and development investments, quality and taste of reformulated foods, supply chain management, operational modifications, consumer acceptance, and cost. The conference facilitated an exchange of ideas and set the stage for potential collaboration opportunities among stakeholders with mutual interest in reducing sodium in the food supply and in Americans' diets. Population-wide sodium reduction remains a critically important component of

To document food acquisition experiences during Iraqi military occupation in Kuwait. Retrospective cross-sectional study. Urban areas in Kuwait during occupation. Those living in Kuwait during the period of occupation, and aged between 15 to 50 years at the time of occupation, recruited by snowball sampling. A total of 390 completed questionnaires (response rate 78%, 202 female and 188 male) were returned. During the occupation, food became increasingly difficult to acquire. Two food systems emerged: (i) an underground Kuwaiti network linked to foods recovered from local food cooperatives and (ii) a black market supplied by food imported through Iraq or stolen locally. Food shortages led to reductions in meal size and frequency. Some respondents (47·7%) reported not having sufficient income to purchase food and 22·1% had to sell capital items to purchase food. There was a significant increase (Pbehaviour change. Respondents reported deterioration in the quality and availability of fish, milk, and fruit in particular. Despite a decrease in opportunities for physical activity, most respondents reported that they lost weight during the occupation. Although the Kuwaiti population fell by about 90 % and domestic food production increased during the 7-month occupation, the local population continued to rely heavily on imported food to meet population needs. The high prevalence of self-reported weight loss indicates the inadequacies of this food supply. High apparent food security in systems which significantly exceed the ecological carrying capacity of the local environment and rely on mass food importation remains vulnerable.

2013-12-01

Full Text Available Background & Objectives: Giardiasis is one of the parasitic infections in the gastrointestinal tract which caused by flagellate protozoa that called giardia and it causes diarrhea. Giardia cysts defecate from infected people. These cysts can enter the body through contaminated hands, water, and food products. Diarrhea, weight loss, abdominal pains, growth failure, malabsorption of carbohydrates, fats and vitamins are the giardiasis symptoms. Methods: In this study, samples were taken from 203 people that were working in different food supply and distribution centers in the South Pars petrochemical. After sampling, samples were analyzed according to standard procedures. The results of examinations were studied after verification them by laboratory chief and their related physicians. Results: Out of the whole examined people in this study, kitchen (28% and salad maker (14% centers were the maximum and minimum population, respectively. 8.87% of the total populations were infected by giardia, which salad making center had the greatest share. As well as, the rate of infectious by giardia among the administrative and dishes washing centers was the lowest. Conclusion: Education level and personal hygiene such as hand washing with a detergent can be important in reducing infection due to giardia. So, the training of workers and also periodic testing of individuals can reduce these pollutants.

Borgese, Laura; Bilo, Fabjola; Dalipi, Rogerta; Bontempi, Elza; Depero, Laura E.

2015-11-01

This review provides a comprehensive overview of the applications of total reflection X-ray fluorescence (TXRF) in the field of food analysis. Elemental composition of food is of great importance, since food is the main source of essential, major and trace elements for animals and humans. Some potentially toxic elements, dangerous for human health may contaminate food, entering the food chain from the environment, processing, and storage. For this reason the elemental analysis of food is fundamental for safety assessment. Fast and sensitive analytical techniques, able to detect major and trace elements, are required as a result of the increasing demand on multi-elemental information and product screening. TXRF is suitable for elemental analysis of food, since it provides simultaneous multi-elemental identification in a wide dynamic range of concentrations. Several different matrices may be analyzed obtaining results with a good precision and accuracy. In this review, the most recent literature about the use of TXRF for the analysis of food is reported. The focus is placed on the applications within food quality monitoring of drinks, beverages, vegetables, fruits, cereals, animal derivatives and dietary supplements. Furthermore, this paper provides a critical outlook on the developments required to transfer these methods from research to the industrial and analytical laboratories contexts.
The Spanish Food Industry on Global Supply Chains and Its Impact on Water Resources

Directory of Open Access Journals (Sweden)

Rosa Duarte

2014-12-01

Full Text Available The study of the impact of economic activities on natural resources through global supply chains is increasingly demanded in the context of the growing globalization of economies and product fragmentation. Taking Spain as a case study and a sector with significant economic and environmental impacts, the agri-food industry, the objective of this work is two-fold. First, we estimate the associated water impact, both from the production and consumption perspectives, paying special attention to the water embodied in production exchanges among countries and sectors. To that aim, we use an environmentally-extended multiregional input-output model (MRIO. Second, we assess the main driving factors behind changes in direct and embodied water consumption between the years 1995 and 2009 by means of a structural decomposition analysis. The MRIO model provides a comprehensive estimate of the economic linkages among regions and economic sectors and, therefore, allows calculating the environmental impacts over international value chains. The results indicate that the food industry exerts large impacts on global water resources, particularly given the remarkable interactions with the domestic and foreign agricultural sectors, These growing linkages show how consumption patterns, and, therefore, lifestyles, involve large environmental impacts through the whole and global supply chains.
The Role of Biotechnology in Sustainable Agriculture: Views and Perceptions among Key Actors in the Swedish Food Supply Chain

Karin Edvardsson Björnberg

2015-06-01

Full Text Available Researchers have put forward agricultural biotechnology as one possible tool for increasing food production and making agriculture more sustainable. In this paper, it is investigated how key actors in the Swedish food supply chain perceive the concept of agricultural sustainability and the role of biotechnology in creating more sustainable agricultural production systems. Based on policy documents and semi-structured interviews with representatives of five organizations active in producing, processing and retailing food in Sweden, an attempt is made to answer the following three questions: How do key actors in the Swedish food supply chain define and operationalize the concept of agricultural sustainability? Who/what influences these organizations’ sustainability policies and their respective positions on agricultural biotechnology? What are the organizations’ views and perceptions of biotechnology and its possible role in creating agricultural sustainability? Based on collected data, it is concluded that, although there is a shared view of the core constituents of agricultural sustainability among the organizations, there is less explicit consensus on how the concept should be put into practice or what role biotechnology can play in furthering agricultural sustainability.
The role of food irradiation in food safety and food security

International Nuclear Information System (INIS)

Kaeferstein, F.K.

1996-01-01

In view of the enormous health and economic consequences of foodborne diseases, the World Health Organization (WHO) encourages its Member States to consider all measures to eliminate or reduce foodborne pathogens in food an improve their supplies of safe and nutritious food. With the wholesomeness of irradiated food clearly established by extensive scientific studies, food irradiation has important roles to play in both ensuring food safety and reducing food losses. Food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection of this process may endanger public health and deprive consumers of the choice of foods processed for safety.

Wallgren, Christine; Hoejer, Mattias

2009-01-01

This paper explores the possibilities for reducing future energy use for eating to a sustainable level. A backcasting approach is used to generate an image of the future where energy use for eating is 60% lower in 2050 than in 2000. The currently known potential to reduce energy use in the food supply system for producing, transporting, storing, cooking and eating food is explored and described in terms of a number of distinct changes that are numbered consecutively and presented in both a quantitative and qualitative way. Sweden is used as the case and all data regarding energy use apply for Swedish conditions. An exercise like this illustrates the possible outcome of taking sustainability seriously. If sustainability is to be achieved, some images of the future are needed so that potential targets can be identified. This paper does not present forecasts, but illustrates the kind of changes needed in order to achieve sustainable energy use in the food system.

The increasing thirst for energy to fuel its fast growing economy has made China keen to explore the potential of modern form of bioenergy, biofuel. This study investigates the land and water requirements of biofuel in China with reference to the government biofuel development plans for 2010 and 2020. The concept of land and water footprints of biofuel is applied for the investigation. The result shows that the current level of bioethanol production consumes 3.5-4% of total maize production of the country, reducing market availability of maize for other uses by about 6%. It is projected that depending on the types of feedstock, 5-10% of the total cultivated land in China would need to be devoted to meet the biofuel production target of 12 million metric tons for the year 2020. The associated water requirement would amount to 32-72 km 3 per year, approximately equivalent to the annual discharge of the Yellow River. The net contribution of biofuel to the national energy pool could be limited due to generally low net energy return of conventional feedstocks. The current biofuel development paths could pose significant impacts on China's food supply and trade, as well as the environment. (author)

Excess consumption of added sugars has been associated with a variety of health problems, but there is little information available characterizing added sugar in the Canadian food supply. This study examined the presence and types of added sugars in the packaged food and beverage products available at a major Canadian grocery retailer. We searched the ingredients lists of over 40 000 packaged food products available for sale in March 2015 for a variety of added sugar terms. Proportions of food products containing added sugar were identified overall and within food product categories. Differences in total sugar content were identified between food products with and without added sugar. Overall, 66% of the packaged food products analyzed contained at least 1 added sugar. The added sugar term "sugar" (and its variations) appeared the most frequently, followed by "dextrose." Added sugar presence and total sugar content varied within many product categories but were consistently higher in expected categories such as "beverages." Mean total sugar content was significantly higher in products with added sugar than in those without, both overall ( p added sugar, similar to recent patterns estimated for the US food supply. The results provide an estimation of the baseline characterization of added sugar in the Canadian food supply, which can be used to assess outcomes of future changes to sugar labelling policies in Canada.
Sustainability of processed foods supply chain: Social, economic and territorial performance

Beber Caetano

2016-01-01

Full Text Available In a global market, food companies engaged in sustainable development must now integrate the economic and social component. However the tools to assess it are lacking. Several theoretical frameworks have been developed to define social sustainability and its implementation. The attributional approaches, pathways or capabilities methods have emerged, based on a functional unit of a good or service along the supply chain. This paper proposes a new method to assess social economic and territorial performances of a food chain as a whole on a Territory. It is divided into four components: (i dignity and well-being of workers, (ii contribution to local life, (iii fairness and integrity of business practices, and (iv creation of material and intangible wealth. 50 criteria are used according to international, national or sectoral references. This generic method applicable to any sector of processed food products aims to identify where are the areas of improvement to qualify the sector as socially sustainable. An application to the wine Beaujolais and Burgundy wine was performed from surveys of 35 production and trade operators in 2014. The results show that the sector is particularly effective for the promotion of the territory, local life participation, loyalty and integrity of business practices; some improvement is still possible for the welfare of workers and the creation of material wealth. This method can be coupled with the environmental performance determined by the life cycle analysis in order to assess the sustainability in its entirety.
Considerations for incorporating eicosapentaenoic and docosahexaenoic omega-3 fatty acids into the military food supply chain.

2014-11-01

The U.S. military may consider exploring the inclusion of the long-chain omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in the diets of active duty military personnel. To be successful, certain challenges must be overcome including determining appropriate dosage, ensuring cost efficiency, and optimizing stability. To increase EPA and DHA intake, the military should consider using one of three strategies, including mandates or recommendations on omega-3 supplement usage, contracts to purchase commercially available foods for distribution in the food supply chain, or direct addition of EPA and DHA into currently consumed foods. This review presents the challenges and strategies and provides potential suggestions to the military to increase the likelihood of success.

Consider food become one of the basic human needs in order to survive so food sufficiency become very important. Food sufficiency of soybean commodity in Central Java still depends on imported soybean. Insufficiency of soybean because of there is much gap between local soybean productions and its demand. In the year 2016 the shortage of supply soybean commodity as much 68.79%. Soybean is an important and strategic commodity after rice and corn. The increasing consumption of soybean is related to increasing population, increasing incomes, changing of healthy life style. The aims of this study are to determine the soybean dynamic model based on supply chain perspective, define the proper price of local soybean to trigger increasing of local production, and to define the alternative solution to support food self sufficiency. This study will capture the real condition into dynamics model, then simulate a series of scenario into a computer program to obtain the best results. This study will be conducted the following first scenario with government intervention policy and second without government intervention policy. The best solution of the alternative can be used as government consideration for governmental policy. The results of the propose scenarios showed that self sufficiency on soybean can be achieved after the next 20 years by increasing planting area 4% and land productivity 1% per year.

Flexibility and innovation at creating shapes, adapting processes, and modifying materials characterize composites materials, a "high-tech" industry. However, the absence of standard manufacturing processes and the selection of materials with defined properties hinder the configuration of the composites materials supply chain. An interesting alternative for a "high-tech" industry such as composite materials would be to review supply chain lessons and practices in "low-tech" industries such as food. The main motivation of this study is to identify lessons and practices that comprise innovations in the supply chain of a firm in a perceived "low-tech" industry that can be used to provide guidelines in the design of the supply chain of a "high-tech" industry, in this case composite materials. This work uses the case study/site visit with analogy methodology to collect data from a Spanish leading producer of fresh fruit juice which is sold in major European markets and makes use of a cold chain. The study highlights supply base management and visibility/traceability as two elements of the supply chain in a "low-tech" industry that can provide guidelines that can be used in the configuration of the supply chain of the composite materials industry.
The global economic and regulatory determinants of household food waste generation: A cross-country analysis.

Science.gov (United States)

Chalak, Ali; Abou-Daher, Chaza; Chaaban, Jad; Abiad, Mohamad G

2016-02-01

Food is generally wasted all along the supply chain, with an estimated loss of 35percent generated at the consumer level. Consequently, household food waste constitutes a sizable proportion of the total waste generated throughout the food supply chain. Yet such wastes vary drastically between developed and developing countries. Using data collected from 44 countries with various income levels, this paper investigates the impact of legislation and economic incentives on household food waste generation. The obtained results indicate that well-defined regulations, policies and strategies are more effective than fiscal measures in mitigating household food waste generation.

2008-11-01

Full Text Available Humans and animals are exposed to aflatoxins by consuming foods contaminated with products of fungal growth. Such exposure is difficult to avoid because fungal growth in foods is not easy to prevent. Even though heavily contaminated food supplies are not distributed at market in developed countries, concern still remains for the possible adverse effects as a consequence of long-term exposure to low levels of aflatoxins in the food supply. Thence the aim of this study was determination of total aflatoxins in dry fruits and nuts.

Spatiotemporal dynamics of a predator–prey system in presence of spatial diffusion is investigated in presence of additional food exists for predators. Conditions for stability of Hopf as well as Turing patterns in a spatial domain are determined by making use of the linear stability analysis. Impact of additional food is clear from these conditions. Numerical simulation results are presented in order to validate the analytical findings. Finally numerical simulations are carried out around the steady state under zero flux boundary conditions. With the help of numerical simulations, the different types of spatial patterns (including stationary spatial pattern, oscillatory pattern, and spatiotemporal chaos) are identified in this diffusive predator–prey system in presence of additional food, depending on the quantity, quality of the additional food and the spatial domain and other parameters of the model. The key observation is that spatiotemporal chaos can be controlled supplying suitable additional food to predator. These investigations may be useful to understand complex spatiotemporal dynamics of population dynamical models in presence of additional food.

Food supply is a major factor influencing growth rates in animals. This has important implications for both natural and farmed fish populations, since food restriction may difficult reproduction. However, a study on the effects of food supply on the development of juvenile gonads has never been transcriptionally described in fish. This study investigated the consequences of growth on gonadal transcriptome of European sea bass in: 1) 4-month-old sexually undifferentiated fish, comparing the gonads of fish with the highest vs. the lowest growth, to explore a possible link between transcriptome and future sex, and 2) testis from 11-month-old juveniles where growth had been manipulated through changes in food supply. The four groups used were: i) sustained fast growth, ii) sustained slow growth, iii) accelerated growth, iv) decelerated growth. The transcriptome of undifferentiated gonads was not drastically affected by initial natural differences in growth. Further, changes in the expression of genes associated with protein turnover were seen, favoring catabolism in slow-growing fish and anabolism in fast-growing fish. Moreover, while fast-growing fish took energy from glucose, as deduced from the pathways affected and the analysis of protein-protein interactions examined, in slow-growing fish lipid metabolism and gluconeogenesis was favored. Interestingly, the highest transcriptomic differences were found when forcing initially fast-growing fish to decelerate their growth, while accelerating growth of initially slow-growing fish resulted in full transcriptomic convergence with sustained fast-growing fish. Food availability during sex differentiation shapes the juvenile testis transcriptome, as evidenced by adaptations to different energy balances. Remarkably, this occurs in absence of major histological changes in the testis. Thus, fish are able to recover transcriptionally their testes if they are provided with enough food supply during sex differentiation; however

The analysis of the interactions among natural disasters and food security is particularly significant for developing countries where food availability (one of the four pillars of food security together with access, utilization and stability) can be highly jeopardize by extreme events that damage the primary access to food, i.e. the agriculture. The main objective of this study is to analyze the impact of flood events on food security for two disastrous flood events in Bangladesh on 2007 and in Pakistan on 2010, selected here as case studies based on the existing literature related to extreme floods.The adopted methodology integrates remote sensing data, agricultural statistics, and water footprint values in order to (i) evaluating the potentially affected agricultural areas; (ii) converting the affected areas into crop loss; (iii) estimating the associated calories and water footprint losses. In Bangladesh, the estimated lost rice is around 12.5% of the total potential production, which implies a 5.3% calories loss with respect to the total potential energy provided by rice and 4.4% of total WF associated to national food supply. In Pakistan, the results show a crops loss of 19% for sugarcane and 40% for rice, with a related calories loss of 8.5% and a WF loss of 13.5%.The results highlight the countries vulnerability to flood, being both countries strongly dependent on local agricultural production. The 2007 flood event reflected critically upon Bangladeshi food security, almost doubling the existing food deficit. The same happened in Pakistan where an already scarce food supply has been worsened by the 2010 flood.Method results are fully repeatable; whereas, for remote sensed data the sources of data are valid worldwide and the data regarding land use and crops characteristics are strongly site specific, which need to be carefully evaluated.These case studies stress the importance of integrating different analysis approaches to carry out an assessment of the

Total nondigestible carbohydrate (NDC) in foods was determined by combining, not modifications, AOAC Official Methods 991.43, 2001.03, and 2002.02. Total NDC included insoluble dietary fiber (IDF) + high-molecular-weight soluble dietary fiber (HMWSDF), nondigestible oligosaccharides (NDO) not precipitated in ethanol solution, and resistant starch (RS). Eight sources of NDC (cellulose, wheat bran, gum arabic, resistant maltodextrin, polydextrose, fructooligosaccharide, galactooligosaccharides, and RS) were incorporated in different combinations into standard formula bread samples. All of the NDC sources and bread samples were analyzed for their (1) IDF + HMWSDF content with corrections for residual RS amount using AOAC Official Method 991.43, (2) NDO by liquid chromatography (LC) in AOAC Official Method 2001.03, and (3) RS by AOAC Official Method 2002.02. The correlation coefficient (R(2)) comparing calculated amounts versus measured amounts of total NDC in 11 bread samples was 0.92. Analysis of commercial food samples was also well matched with the DF + NDO value on their nutritional label. Consequently, we confirmed a single measurement of LC can determine all NDO in foods, and total NDC in foods can be determined by unifying existing AOAC Official Methods.

Full Text Available The availability of systems for automatic and simultaneous identification of several items belonging to a logistics unit during production, warehousing and delivering can improve supply chain management and speed traceability controls. Radio frequency identification (RFID is a powerful technique that potentially permits to reach this goal, but some aspects as, for instance, food product composition (e.g. moisture content, salt or sugar content and some peculiarities of the production environment (high moisture, high/low temperatures, metallic structures have prevented, so far, its application in food sector. In the food industry, composition and shape of items are much less regular than in other commodities sectors. In addition, a wide variety of packaging, composed by different materials, is employed. As material, size and shape of items to which the tag should be attached strongly influence the minimum power requested for tag functioning, performance improvements can be achieved only selecting suitable RF identifier for the specific combination of food product and packaging. When dealing with logistics units, the dynamic reading of a vast number of tags originates simultaneous broadcasting of signals (tag-to-tag collisions that could affect reading rates and the overall reliability of the identification procedure. This paper reports the results of an extensive analysis of the reading performance of UHF RFID systems for multiple dynamic electronic identification of food packed products in controlled conditions. Products were considered singularly or arranged on a logistics pallet. The effects on reading rate and reading zone of different factors, among which the type of product, the number and position of antennas, the field polarization, the reader RF power output, the interrogation protocol configuration as well as the transit speed, the number of tags and their interactions were analysed and compared.

Food is the major route of human intake of toxic dioxin-like compounds (DLCs), which include PolyChlorinated Dibenzo-p-Dioxins (PCDDs), PolyChlorinated Dibenzo-p-Furans (PCDFs), and PolyChlorinated Biphenyls (PCBs). Approximately 95% of human DLCs exposure derives from food, with nearly 80% coming from food of animal origin. The DLCs levels in foodstuffs and the food consumption rate are essential to evaluate health risk posing to humans. The lack of DLCs levels in food increases the population's risk to DLCs exposure. The Department of Health, Taiwan has entrusted us to conduct a comprehensive monitoring program on PCDD/Fs levels in Taiwan food (not including plant origin) in 2001 and 2002, In 2003, the program has extended the analytes to include 12 WHO-PCBs. A total diet study (TDS) of DLCs intake from Taiwan food is, therefore, conducted for the first time. The DLCs concentrations in food of animal origin and the food consumption rate are collected. The average daily intake (ADI) and average weekly intake (AWI) of DLCs from food by Taiwan adults is determined.

Vertical Cost-Information Sharing in a Food Supply Chain with Multiple Unreliable Suppliers and Two Manufacturers

Directory of Open Access Journals (Sweden)

Junjian Wu

2017-01-01

Full Text Available This paper considers a food supply chain where multiple suppliers provide completely substitutable food products to two manufacturers. Meanwhile, the suppliers face yield uncertainty and the manufacturers face uncertain production costs that are private information. While the suppliers compete on price, the manufacturers compete on quantity. We build a stylized multistage game theoretic model to analyze the issue of vertical cost-information sharing (VCIS within the supply chain by considering key parameters, including the level of yield uncertainty, two manufacturers’ cost correlation, the correlated coefficient of suppliers’ yield processes, and the number of suppliers. We study the suppliers’ optimal wholesale price and the manufacturers’ optimal order quantities under different VCIS strategies. Finally, through numerical analyses, we examine how key parameters affect the value of VCIS to each supplier and each manufacturer, respectively. We found that the manufacturers are willing to share cost information with suppliers only when the two manufacturers’ cost correlation is less than a threshold. While a high correlated coefficient of suppliers’ yield processes and a large number of suppliers promote complete information sharing, a high level of yield uncertainty hinders complete information sharing. All these findings have important implications to industry practices.

A radiological survey was conducted from September through November of 1978 to assess the concentrations of persistent manmade radionuclides in the terrestrial and marine environments of 11 atolls and 2 islands in the Northern Marshall Islands. The survey consisted mainly of an aerial radiological reconnaissance to map the external gamma-ray exposure rates over the islands of each atoll. The logistical support for the entire survey was designed to accommodate this operation. As a secondary phase of the survey, shore parties collected appropriate terrestrial and marine samples to assess the radiological dose from pertinent food chains to those individuals residing on the atolls, who may in the future reside on some of the presently uninhabited atolls, or who collect food from these atolls. Over 5000 terrestrial and marine samples were collected for radionuclide analysis from 76 different islands. Soils, vegetation, indigenous animals, and cistern water and groundwater were collected from the islands. Reef and pelagic fish, clams, lagoon water, and sediments were obtained from the lagoons. The concentration data for 90 Sr, 137 Cs, 238 Pu, 239 240 Pu, and 241 Am in terrestrial food crops, fowl, and animals collected at the atolls or islands are summarized. An assessment of the total dose from the major exposure pathways including external gamma, terrestrial food chain including food products and drinking water, marine food chain, and inhalation is provided. Radiological doses at each atoll or island are calculated from the average radionuclide concentrations in the terrestrial foods, marine foods, etc. assuming the average daily intake for each food item

Flexibility and innovation at creating shapes, adapting processes, and modifying materials characterize composites materials, a “high-tech” industry. However, the absence of standard manufacturing processes and the selection of materials with defined properties hinder the configuration of the composites materials supply chain. An interesting alternative for a “high-tech” industry such as composite materials would be to review supply chain lessons and practices in “low-tech” industries such as food. The main motivation of this study is to identify lessons and practices that comprise innovations in the supply chain of a firm in a perceived “low-tech” industry that can be used to provide guidelines in the design of the supply chain of a “high-tech” industry, in this case composite materials. This work uses the case study/site visit with analogy methodology to collect data from a Spanish leading producer of fresh fruit juice which is sold in major European markets and makes use of a cold chain. The study highlights supply base management and visibility/traceability as two elements of the supply chain in a “low-tech” industry that can provide guidelines that can be used in the configuration of the supply chain of the composite materials industry.

Dairy Food at the First Occasion of Eating Is Important for Total Dairy Food Intake for Australian Children

Directory of Open Access Journals (Sweden)

Malcolm D. Riley

2014-09-01

Full Text Available The cross-sectional 2007 Australian National Children’s Nutrition and Physical Activity Survey collected detailed dietary information from a representative sample of more than 4400 children by 24-h dietary recall. Dairy food intake by Australian children is substantially lower than recommendations, and decreases as a percentage of energy intake as children grow older. Children aged 2 to 16 years are, on average, 2.3 times more likely to have a dairy food at the first daily occasion of eating, than at the second occasion. For children who consumed any dairy food at the first occasion of eating, the total daily intake of dairy foods was 129% (95% CI 120%–138% greater than for children who did not consume a dairy food at the first occasion of eating. Their dairy food intake for the rest of the day following the first occasion of eating was also greater by 29% (95% CI 21%–37%. Younger age group, male sex, location of eating being at home or in a residence and starting the first occasion of eating from 6 a.m. to 9 a.m. are all jointly associated with having a dairy food at the first occasion of eating. A simple strategy to increase Australian children’s intake from the dairy and alternatives food group may be to make sure that the first occasion of eating each day includes a dairy food or a nutritional equivalent.

Strategies and behaviors used to manage the household food supply. Emergent and thematic qualitative coding of open-ended responses. The top 3 strategies and behaviors to change meals were (1) changes in foods purchased or obtained for the household, (2) monetary and shopping strategies, and (3) adaptations in home preparation. The most frequently mentioned foods that were decreased were protein foods (eg, meat, eggs, beans), fruits, and vegetables. The most frequently mentioned foods that were increased were grains and starches (eg, noodles), protein foods (eg, beans, hot dogs), and mixed foods (eg, sandwiches). Caregivers use a wide variety of strategies and behaviors to manage the household food supply when their children are food insecure. Future work should examine how these strategies might affect dietary quality and well-being of food-insecure children. Copyright © 2016 Society for Nutrition Education and Behavior.

The total arsenic, inorganic arsenic, lead, cadmium, and mercury contents of 18 algae food products currently on sale in Spain were determined. The suitability of the analytical methodologies for this type of matrix was confirmed by evaluating their analytical characteristics. The concentration ranges found for each contaminant, expressed in milligrams per kilogram of dry weight, were as follows: total arsenic, 2.3-141; inorganic arsenic, 0.15-88; lead, mercury, 0.004-0.04. There is currently no legislation in Spain regarding contaminants in algae food products, but some of the samples analyzed revealed Cd and inorganic As levels higher than those permitted by legislation in other countries. Given the high concentrations of inorganic As found in Hizikia fusiforme, a daily consumption of 1.7 g of the product would reach the Provisional Tolerable Weekly Intake recommended by the WHO for an average body weight of 68 kg. A more comprehensive study of the contents and toxicological implications of the inorganic As present in the algae food products currently sold in Spain may be necessary, which might then be the basis for the introduction of specific sales restrictions.

Biofuels and food security: Micro-evidence from Ethiopia

International Nuclear Information System (INIS)

Negash, Martha; Swinnen, Johan F.M.

2013-01-01

There is considerable controversy about the impact of biofuels on food security in developing countries. A major concern is that biofuels reduce food security by increasing food prices. In this paper we use survey evidence to assess the impact of castor production on poor and food insecure rural households in Ethiopia. About 1/3 of poor farmers have allocated on average 15% of their land to the production of castor beans under contract in biofuel supply chains. Castor production significantly improves their food security: they have fewer months without food and the amount of food they consume increases. Castor cultivation is beneficial for participating households’ food security in several ways: by generating cash income from castor contracts, they can store food for the lean season; castor beans preserve well on the field which allows sales when farmers are in need of cash (or food); spillover effects of castor contracts increases the productivity of food crops. Increased food crop productivity offsets the amount of land used for castor so that the total local food supply is not affected. - Highlights: • We evaluate the impact of biofuel production contracts on farmers’ food security. • We apply endogenous switching regression method on survey data from Ethiopia. • Impact is heterogeneous across groups. • Food security significantly improved for contract participants by 25%. • Spillover effects improve food productivity that offsets the amount of land diverted to biofuel
The Analysis of Orders of Perishable Goods in Relation to the Bullwhip Effect in the Logistic Supply Chain of the Food Industry: a Case Study

Science.gov (United States)

Chocholáč, Jan; Průša, Petr

2016-12-01

The bullwhip effect generally refers to the phenomenon where order variability increases as the orders move upstream in the supply chain. It is serious problem for every member of the supply chain. This effect begins at customers and passes through the chain to producers, which are at the end of the logistic chain. Especially food supply chains are affected by this issue. These chains are unique for problems of expiration of goods (particularly perishable goods), variable demand, orders with quantity discounts and effort to maximize the customer satisfaction. This paper will present the problem of the bullwhip effect in the real supply chain in the food industry. This supply chain consists of approximately 350 stores, four central warehouses and more than 1000 suppliers, but the case study will examine 87 stores, one central warehouse and one supplier in 2015. The aim of this paper is the analysis of the order variability between the various links in this chain and confirmation of the bullwhip effect in this chain. The subject of the analysis will be perishable goods.

Full Text Available Major businesses around the world have been trying to reduce the total cost and wastes across their supply chain to remain competitive in the expanding global market. Hence, a collection of reliable tools and techniques are vital for decreasing costs and wastes and for providing effective services for customer demands. Given that lean concept attempts to decrease costs and wastes, this study aims to identify the effective lean tools required for eliminating wastes in the supply chain. Because of the large number of consumers and the global market of Halal products, this study focuses on Halal food supply chains. Out of the questionnaires distributed to 300 Halal food firms in Malaysia, only 61 usable replies were obtained. The results showed that demand collaboration, continuous improvement, and inventory management practices are the most important tools in Lean Supply Chain (LSC implementation. In addition, the results indicated that only a small percentage of Halal food companies are implementing LSC. Malaysia is an important Halal food producer in the word, but has low level of LSC implementation among its Halal food producers. LSC is a new concept that needs more effort to be understood and implemented.

Population growth and food supply in sub-Saharan Africa.

Science.gov (United States)

Meerman, J; Cochrane, S H

1982-09-01

It is argued in this article that sub-Saharan Africa, given its present institutions and endowments of capital and technology, is already dangerously close to overpopulation. The rapid growth of its population projected for the next decades will greatly increase human misery and depress economic development. Specifically, rapid population growth will have disastrous effects on the region's ability to increase exports and provide people with food. There must be a search for new ways in which these effects could be mitigated. In sub-Saharan Africa fertility either continues to be very high or is increasing, in part due to some decline in traditional practices that reduce fertility, such as prolonged breastfeeding. This situation and the expectation of declining mortality imply that African population growth may increase further. Currently, population in sub-Saharan Africa is about half that of India and a third of China. There are 2 main reasons why reduced fertility in the next few decades is unlikely in sub-Saharan Africa as a whole: Africa has low literacy, high infant and child mortality, and low urbanization; and average African fertility rates may even increase for the next 20 years or so. The question that arises is what are the implications of continuing and rapid population growth for the African food supply. The region's cereal production is largely restricted to 4 grains, i.e., millet, sorghum, maize, and rice. The volume of grain production is less, by weight, than 60% of the production of roots and tubers. There are 2 main differences between the output of these crops in sub-Saharan Africa and the rest of the world: yields/hectare are lower in Africa than in elsewhere; and yields have generally been decreasing or largely constant in Africa. The low productivity has several causes. Today, population pressure has brought diminishing returns to traditional agriculture in much of the Sahel and the savanna, in parts of East Africa, Southern Africa, and parts

Food security is an important issue that is of concern for all countries around the world. There are many factors which may cause food insecurity including increasing demand, shortage of supply, trade condition, another countries' food policy, lack of money, high food and oil prices, decelerating productivity, speculation, etc. The food self-sufficiency ratio of Taiwan is only 30.6% weighted by energy in 2007. Total agriculture imports and cereals have increased significantly due to the expansion of livestock and fishery industries and improve living standard. The agriculture sector of Taiwan is facing many challenges, such as: low level of food self-sufficiency, aging farmers, large acreage of set-aside farmlands, small scale farming, soaring price of fertilizers, natural disasters accelerated by climate change, and rapid changes in the world food economy. To cope with these challenges, the present agricultural policy is based on three guidelines: "Healthfulness, Efficiency, and Sustainability." A program entitled "Turning Small Landlords into Large Tenants" was launched to make effective use of idle lands. Facing globalization and the food crisis, Taiwan will secure stable food supply through revitalization of its set-aside farmlands and international markets, and provide technical assistance to developing countries, in particular for staple food crops.

One of the main logistic challenges in this sector is to deal with the high dynamics and uncertainty in supply and demand. This paper discusses the opportunities of Future Internet (FI technologies to addresses the specific demands on information systems for logistics in the food and agribusiness domain. More specifically, it presents a Future Internet (FI based design for smart agri‐food logistic information systems. This design aims to enable new types of efficient and responsive logistics networks with flexible chain‐encompassing tracking and tracing systems and decision support based on that information. These systems effectively virtualise the logistics flows from farm to fork, support a timely and error‐free exchange of logistics information and provide functionality for intelligent analysis and reporting of exchanged data to enable early warning and advanced forecasting.
Seven Fundamental Economic Characteristics Exclusivity of Agrifood Supply Chains (part 2

Directory of Open Access Journals (Sweden)

Thomas L. Sporleder

2013-12-01

Full Text Available This analysis focuses on defining and describing the unique economic characteristics of agrifood supply chains. The analysis includes seven specific economic characteristics of agrifood supply chains that distinguish them from other industrial manufacturing and service supply chains. The seven characteristics are: 1 risk emanating from the biological nature of agrifood supply chains, 2 the role of buffer stocks within the supply chain, 3 the scientific foundation of innovation in production agriculture having shifted from chemistry to biology, 4 cyberspace and information technology influences on agrifood supply chains, 5 the prevalent market structure at the farm gate remains oligopsony, 6 relative market power shifts in agrifood supply chains away from food manufacturers downstream to food retailers, and 7 globalization of agriculture and agri- food supply chains.

Private-label brands account for about one in four foods sold in US supermarkets. They provide value to consumers due to their low cost. We know of no US studies comparing the nutrition content of private-label products with corresponding national brand products. The objective was to compare concentrations of sodium and related nutrients (potassium, total dietary fiber, total and saturated fat, and total sugar) in popular sodium-contributing, commercially packaged foods by brand type (national or private-label brand). During 2010 to 2014, the Nutrient Data Laboratory of the US Department of Agriculture obtained 1,706 samples of private-label and national brand products from up to 12 locations nationwide and chemically analyzed 937 composites for sodium and related nutrients. The samples came from 61 sodium-contributing, commercially packaged food products for which both private-label and national brands were among the top 75% to 80% of brands for US unit sales. In this post hoc comparative analysis, the authors assigned a variable brand type (national or private label) to each composite and determined mean nutrient contents by brand type overall and by food product and type. The authors tested for significant differences (Pfoods sampled, differences between brand types were not statistically significant for any of the nutrients studied. However, differences in both directions exist for a few individual food products and food categories. Concentrations of sodium and related nutrients (potassium, total dietary fiber, total and saturated fat, and total sugar) do not differ systematically between private-label and national brands, suggesting that brand type is not a consideration for nutritional quality of foods in the United States. The study data provide public health officials with baseline nutrient content by brand type to help focus US sodium-reduction efforts. Published by Elsevier Inc.

Omar, Marina; Mustaffa, Noorfa Haszlinna H.; Othman, Siti Norsyahida

2013-04-01

Supply Chain Management (SCM) is an important activity in all producing facilities and in many organizations to enable vendors, manufacturers and suppliers to interact gainfully and plan optimally their flow of goods and services. A simulation optimization approach has been widely used in research nowadays on finding the best solution for decision-making process in Supply Chain Management (SCM) that generally faced a complexity with large sources of uncertainty and various decision factors. Metahueristic method is the most popular simulation optimization approach. However, very few researches have applied this approach in optimizing the simulation model for supply chains. Thus, this paper interested in evaluating the performance of metahueristic method for stochastic supply chains in determining the best flexible inventory replenishment parameters that minimize the total operating cost. The simulation optimization model is proposed based on the Bees algorithm (BA) which has been widely applied in engineering application such as training neural networks for pattern recognition. BA is a new member of meta-heuristics. BA tries to model natural behavior of honey bees in food foraging. Honey bees use several mechanisms like waggle dance to optimally locate food sources and to search new ones. This makes them a good candidate for developing new algorithms for solving optimization problems. This model considers an outbound centralised distribution system consisting of one supplier and 3 identical retailers and is assumed to be independent and identically distributed with unlimited supply capacity at supplier.

Modern food production depends on limited natural resources for providing energy and fertilisers. We assess the fossil fuel dependency for the Danish food production system by means of Food Energy Returned on fossil Energy Invested (Food-EROI) and by the use of energy intensive nutrients from....... Furthermore, nutrients in commercial fertiliser and imported feed account for 84%, 90% and 90% of total supply of N, P and K, respectively. We conclude that the system is unsustainable because it is embedded in a highly fossil fuel dependent system based on a non-circular flow of nutrients. As energy and thus...... imported livestock feed and commercial fertilisers. The analysis shows that the system requires 221 PJ of fossil energy per year and that for each joule of fossil energy invested in farming, processing and transportation, 0.25 J of food energy is produced; 0.28 when crediting for produced bioenergy...

Full Text Available The competitiveness of a supply chain is driven by the ability of supply chain governance structures to adapt to the chains’ continuously changing technical and organizational characteristics. The present study addresses the adoption of sustainability improvement options in the area of organization and management in the agri-food sector; within this framework the study proposes a tool for assessing the impact of sustainability oriented processes on the supply chain governance structures, in turn influencing the competitiveness of the supply chain. Two different approaches, proposed by (Gereffi et al., 2005 and (Hobbs and Young, 2000 have been linked to provide a theoretical framework for the tool development. The proposed new conceptual framework links the dimensions defining five different governance structures complexity of transaction, ability to codify and capabilities in the supply-base (Gereffi et al., to the product characteristics, regulatory and technology aspects defined by Hobbs and Young as drivers influencing the vertical coordination of supply chains. The method suggested for measuring the relations between improvement options and the chain governance structure is the adoption of experts’ evaluations. This method improves the tool capacity to provide a context-related supply chain governance structure assessment and management.

The food technology has brought countless benefits to today's food supply. Despite its many positive contributions, it has also brought unintended negative consequences. It is the time to mobilize the food technology to help the food supply more secure, safer and healthier, and here three possible approaches are foreseeable: First, we should continue to improve the conventional technologies. Many wholesome foods have been prepared and preserved using natural materials simply by fermentation. Second, we have to enhance the minimal processing as much as applicable. Third, new ingredients, intelligent packaging and functional foods should be explored to improve food supply and health. Today, consumer interest in the functional foods has been increased tremendously, and the future of food lies in the functional foods. However, the situations in the developing world are different from this. As food resource is limited in this region, food technology has to be emphasized to increase food supply. To help solve such complex problems, not only new technologies, but also conventional technologies have to be mobilized. Simultaneously, even higher technical capabilities have to be built up by applying new findings from the related disciplines to allow the food technology to play its vital role.

Aiming at the lack of a comprehensive evaluation of the distribution network, based on the existing distribution network evaluation index system, combined with the basic principles of constructing the evaluation index, put forward a new evaluation index system of distribution network capacity. This paper is mainly based on the total supply capability of the distribution network, combining single index and various factors, into a multi-evaluation index of the distribution network, thus forming a reasonable index system, and various indicators of rational quantification make the evaluation results more intuitive. In order to have a comprehensive judgment of distribution network, this paper uses weights to analyse the importance of each index, verify the rationality of the index system through the example, it is proved that the rationality of the index system, so as to guide the direction of distribution network planning.

Since the risk of food-borne pathogenic diseases such as E. coli O157:H7 and Salmonella always remains in the military meal service system, it is necessary to develop the method to eliminate this problem. According to the preference survey of military meals, it is shown that soldiers preferred the improvement in quality such as tastes and variety to the increase in quantity. For this reason, the supply of diverse foods, improvement of cooking methods, and the complement of meal service facilities are required. The developed countries such as the United States maintain the facilities to control the environmental factors such as temperature, moisture, and oxygen and they develop and use the rapid methods to test the storage times of each category of foods based on the theoretical studies of food storage/preservation/processing and their experimental data. Due to the ordinary sanitation methods are gradually limited all over the world, as new technology for prevention of food-borne diseases and establishment to manufacture wholesome food, a radiation technology is very effective to ensure safe food and preservation/distribution, improve the safety of processed food and its manufacturing processes. And, the military meal service including combat rations furnishes viability, energy, ability for duty, and mental rest to soldiers. Furthermore, it ensures combat capabilities, enhances mobility power of troops, improves combat efficiency, and establishes the military supply system. It is necessary to study irradiation technique in order to establish the safe food supply system for military meal service and eliminate contamination such as food-borne disease for combat crews as an essential element in military power

To examine purchase patterns at fast-food restaurants and their relation to restaurant characteristics, customer characteristics, and use of calorie information. Cross-sectional survey. Fast-food restaurants in New York State. Adult fast-food restaurant customers (n = 1,094). Restaurant characteristics (fast-food chain type, presence of calorie labels, and poverty of location), participant characteristics (demographics, calorie knowledge, awareness, and use), and customer purchasing patterns (ordering low-calorie or no beverage, small or no fries, or restaurant and customer characteristics, fast-food chain customer age, sex, calorie use, and calorie awareness were independently associated with total calories purchased (all P < .05; model R2 = .19). When 3 purchasing patterns were added to the model, calorie use (P = .005), but not calorie awareness, remained associated with total calories purchased. The 3 purchase patterns collectively accounted for the majority of variance in calorie totals (Δ model R2 = .40). Promoting use of calorie information, purchase strategies, and calorie awareness represents complementary ways to support lower-calorie choices at fast-food chains.

Fast foods are often energy dense and offered in large serving sizes. Observational data have linked the consumption of fast foods to an increased risk of obesity and related diseases. We surveyed the reported energy, total fat and saturated fat contents, and serving sizes, of fast-food items from five major chains across ten countries, comparing product categories as well as specific food items available in most countries. MRC Human Nutrition Research, Cambridge, UK. Data for 2961 food and drink products were collected, with most from Canada (n 550) and fewest from the United Arab Emirates (n 106). There was considerable variability in energy and fat contents of fast foods across countries, reflecting both the portfolio of products and serving size variability. Differences in total energy between countries were particularly noted for chicken dishes (649-1197 kJ/100 g) and sandwiches (552-1050 kJ/100g). When comparing the same product between countries variations were consistently observed in total energy and fat contents (g/100 g); for example, extreme variation in McDonald's Chicken McNuggets with 12 g total fat/100 g in Germany compared with 21·1 g/100 g in New Zealand. These cross-country variations highlight the possibility for further product reformulation in many countries to reduce nutrients of concern and improve the nutritional profiles of fast-food products around the world. Standardisation of serving sizes towards the lower end of the range would also help to reduce the risk of overconsumption.

Loss and waste in the food supply chain: an introduction to the problem

Directory of Open Access Journals (Sweden)

Sebastian Stępień

2017-07-01

Full Text Available The problem of food waste is particularly relevant in the twenty-first century. According to the data from the Food Banks, 1.3 billion tonnes of food is wasted every year around the world. This represents a third of the total food production. In Europe, there are almost 100 million tonnes and in Poland there are some 9 million tonnes per annum (Food Banks 2016. The data on Europe do not include losses in agriculture and fisheries, which, in fact, make this figure much higher. However, the scale of waste in sub-Saharan Africa and Asia is much lower and there is a chronic problem of malnutrition and even starvation. As reported by UNICEF, malnutrition is the cause of death of over 5 million children annually (UNICEF 2016. It is therefore necessary to develop strategies to effectively combat this phenomenon. Such attempts are taken by the European Union, which pays attention to the problem in the strategy ‘Europe 2020’. In 2011, the European Parliament adopted a resolution ‘How to avoid food waste: a strategy for improving the efficiency of the food chain in the EU’. At the same time a large part of the EU population (including Poles declare that they are not aware of the situation, do not notice information campaigns and programmes that aim to reduce food waste. Struggle with this twenty-first century problem should therefore start from building attitudes and awareness of individual households and firms engaged in food production and distribution. The purpose of this article is to point to the problem of food waste, its causes and manifestations, and to identify possible strategies to combat this phenomenon. Research methods used in this work include a critical literature analysis and meta-analysis with elements of deductive reasoning based on available literature and reports.
Estimating Swedish biomass energy supply

International Nuclear Information System (INIS)

Johansson, J.; Lundqvist, U.

1999-01-01

Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy
Trade and commerce in improved crops and food: an essay on food security.

Science.gov (United States)

Kershen, Drew L

2010-11-30

Agricultural trade between nations is a significant proportion of total international trade. Agricultural trade in transgenic crops faces extra complications due to the existence of domestic and international regimes that focus specifically on agricultural biotechnology. These specialized regimes create legal and commercial challenges for trade in transgenic crops that have significant implications for the food security of the nations of the world. By food security, one should understand not just the available supply of food, but also the quality of the food and the environmental impact of agricultural production systems. These specialized regimes for transgenic crops can either encourage or hinder the adoption of agricultural biotechnology as a sustainable intensive agriculture. Sustainable intensive agriculture offers hope for agronomic improvements for agricultural production, socio-economic betterment for farmers and environmental benefits for societies. Sustainable intensive agriculture offers particular hope for the poorest farmers of the world because agricultural biotechnology is a technology in the seed. Copyright © 2010 Elsevier B.V.

The effect of governance mechanisms on food safety in the supply chain: Evidence from the Lebanese dairy sector.

Science.gov (United States)

Abebe, Gumataw K; Chalak, Ali; Abiad, Mohamad G

2017-07-01

Food safety is a key public health issue worldwide. This study aims to characterise existing governance mechanisms - governance structures (GSs) and food safety management systems (FSMSs) - and analyse the alignment thereof in detecting food safety hazards, based on empirical evidence from Lebanon. Firm-to-firm and public baseline are the dominant FSMSs applied in a large-scale, while chain-wide FSMSs are observed only in a small-scale. Most transactions involving farmers are relational and market-based in contrast to (large-scale) processors, which opt for hierarchical GSs. Large-scale processors use a combination of FSMSs and GSs to minimise food safety hazards albeit potential increase in coordination costs; this is an important feature of modern food supply chains. The econometric analysis reveals contract period, on-farm inspection and experience having significant effects in minimising food safety hazards. However, the potential to implement farm-level FSMS is influenced by formality of the contract, herd size, trading partner choice, and experience. Public baseline FSMSs appear effective in controlling food safety hazards; however, this may not be viable due to the scarcity of public resources. We suggest public policies to focus on long-lasting governance mechanisms by introducing incentive schemes and farm-level FSMSs by providing loans and education to farmers. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Coping with chaos: unpredictable food supplies intensify torpor use in an arid-zone marsupial, the fat-tailed dunnart ( Sminthopsis crassicaudata)

The severity, duration and amplitude of extreme weather events are forecast to intensify with current climate trends, over both long (e.g. seasonal) and short (e.g. daily) time-scales. As such, the predictability of food supplies for many small endotherms is likely to become increasingly important. Numerous small mammals and birds combat food shortages using torpor, a controlled reduction in metabolic rate and body temperature that helps lower their daily energy requirements. As such, torpor often has been cited as a key feature allowing some small endotherms to survive highly unpredictable climates, such as tropics or dry deserts, but mensurative demonstrations of this are lacking. We have shown here that when a small desert marsupial, the fat-tailed dunnart ( Sminthopsis crassicaudata), is offered unpredictable levels of daily food, they increase frequency of daily torpor and length of bouts compared with animals offered ad libitum food, but this was not found for animals offered a 70% food-restricted diet. Our data suggest that simple food restriction may not be sufficient for evaluating the efficacy of torpor as a strategy for managing unpredictable climates.
Empowering billions with food safety and food security

Full text: There are virtually millions of people -who die needlessly every year due to contaminated water and food. There are virtually many millions more who are starving due to an inadequate supply of food. Billions of pounds of food are unnecessarily wasted due to insect and other damage. Deaths and illness due to contaminated food or inadequate food are at catastrophic levels in many regions of the world. A majority of the food and water borne illnesses and deaths are preventable. It can be prevented by improved food production methods, improved food processing technologies, improved food distribution systems and improved personal hygiene. Food irradiation technology is over 100 years old. Yet, this technology is poorly understood by governments and corporate decision makers all around the world. Many consumers also are unfortunately misinformed of this technology. There is an urgent need for nations and people around the world to empower themselves with the knowledge and the expertise to harness this powerful technology. Widespread and sensible adoption of this technology can empower billions around the world with clean and abundant food supplies. It is unconscionable in the 21st century for governments to allow people to die or go hungry when the technology to prevent them is readily available

Regulatory changes in Canada will require food labels to have a benchmark [% Daily Value, %DV] for total sugars, based on 100 g/day, while US labels will require a %DV for added sugars, based on 50 g/day. The objective of this study was to compare two labelling policies, a total sugars DV (100 g/day) and a free sugars DV (50 g/day) on food labels. This cross-sectional analysis of the Food Label Information Program database focussed on top sources of total sugars intake in Canada (n = 6924 foods). Products were categorized as "less healthy" using two sets of criteria: a) free sugars levels exceeding the WHO guidelines (≥10% energy from free sugars); and b) exceeding healthfulness cut-offs of the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (FSANZ-NPSC). The proportion of "less healthy" products with ≥15%DV (defined as "a lot" of sugars i.e. high in sugars, based on Health Canada's %DV labelling footnote and educational message for dietary guidance) were compared for each sugar labelling scenario. The free sugars DV showed better alignment with both methods for assessing "healthfulness" than the total sugars DV. The free sugars DV identified a greater proportion of "less healthy" foods with ≥15%DV, based on both the FSANZ-NPSC (70% vs. 45%, p chocolate bars, confectionery, and frozen desserts categories. Compared to total sugars DV labelling, using a free sugars DV identified more "less healthy" foods. Findings support the adoption of free sugars labelling. Copyright © 2018 Elsevier Inc.

Full Text Available Abstract Background A plant-based diet protects against chronic oxidative stress-related diseases. Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies. Methods We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name were registered for each individual food sample and constitute the Antioxidant Food Table. Results The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values. Conclusions This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non-plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies. The present antioxidant database is therefore an essential research tool to further elucidate the potential

Small food store interventions show promise to increase healthy food access in under-resourced areas. However, none have tested the impact of price discounts on healthy food supply and demand. We tested the impact of store-directed price discounts and communications strategies, separately and combined, on the stocking, sales and prices of healthier foods and on storeowner psychosocial factors. Factorial design randomized controlled trial. Twenty-four corner stores in low-income neighbourhoods of Baltimore City, MD, USA. Stores were randomized to pricing intervention, communications intervention, combined pricing and communications intervention, or control. Stores that received the pricing intervention were given a 10-30 % price discount by wholesalers on selected healthier food items during the 6-month trial. Communications stores received visual and interactive materials to promote healthy items, including signage, taste tests and refrigerators. All interventions showed significantly increased stock of promoted foods v. There was a significant treatment effect for daily unit sales of healthy snacks (β=6·4, 95 % CI 0·9, 11·9) and prices of healthy staple foods (β=-0·49, 95 % CI -0·90, -0·03) for the combined group v. control, but not for other intervention groups. There were no significant intervention effects on storeowner psychosocial factors. All interventions led to increased stock of healthier foods. The combined intervention was effective in increasing sales of healthier snacks, even though discounts on snacks were not passed to the consumer. Experimental research in small stores is needed to understand the mechanisms by which store-directed price promotions can increase healthy food supply and demand.

Full Text Available India and China are two similar developing countries with huge populations, rapid economic growth and limited natural resources, therefore facing the massive pressure of ensuring food security. In this paper, we will discuss the food security situations in these two countries by studying the historical changes of food supply-demand balance with the concept of agricultural land requirements for food (LRF from 1963–2009. LRF of a country is a function of population, per capita consumption/diet, cropping yield and cropping intensity. We have attempted to discuss and compare our results in a framework which links consumption of different groups of food items to diet patterns; then, to the total land requirement for food in a scenario when population is growing rapidly and diet diversification and urbanization due to economic reform impose excessive pressure on food security of both countries. We also elaborate on the role of technology dissemination and critically analyze the achievements and drawbacks of government policies to ensure food self-sufficiency and food security of nations. Our results show that the total LRF increases approximately by 42% and 40%, whereas per capita LRF decreases significantly by about 48% and 30% from 1963–2009, for India and China, respectively. Furthermore, our studies reveal that population growth dominates most of the increase in total LRF for India; whereas diet pattern change induced by income growth drives the major increase in LRF for China. Therefore, sustainable management of agricultural land resource is an urgent need both for India and China as there will be demand for more food to meet the diet requirement for the entire population. We also demonstrate the role of India and China in future global food security programs and the challenges to implement the new land reform policies domestically.

Pathogenic Escherichia coli has been listed among the most important bacteria associated with foodborne illnesses around the world. We investigated the genetic relatedness among Shiga toxin-producing E. coli (STEC) isolated along the animal food supply chain and from humans diagnosed with gastroenteritis in Qatar. Samples were collected from different sources along the food supply chain and from patients admitted to the hospital with complaints of gastroenteritis. All samples were screened for the presence of E. coli O157:H7 and non-O157 STEC using a combination of bacterial enrichment and molecular detection techniques. A proportional sampling approach was used to select positive samples from each source for further multilocus sequence typing (MLST) analysis. Seven housekeeping genes described for STEC were amplified by polymerase chain reaction, sequenced, and analyzed by MLST. Isolates were characterized by allele composition, sequence type (ST) and assessed for epidemiologic relationship within and among different sources. Nei's genetic distance was calculated at the allele level between sample pools in each site downstream. E. coli O157:H7 occurred at a higher rate in slaughterhouse and retail samples than at the farm or in humans in our sampling. The ST171, an ST common to enterotoxigenic E. coli and atypical enteropathogenic E. coli, was the most common ST (15%) in the food supply chain. None of the genetic distances among the different sources was statistically significant. Enterohemorrhagic E. coli pathogenic strains are present along the supply chain at different levels and with varying relatedness. Clinical isolates were the most diverse, as expected, considering the polyclonal diversity in the human microbiota. The high occurrence of these food adulterants among the farm products suggests that implementation of sanitary measures at that level might reduce the risk of human exposure.
Anthropogenic Food Subsidy to a Commensal Carnivore: The Value and Supply of Human Faeces in the Diet of Free-Ranging Dogs

Full Text Available As the global population of free-ranging domestic dogs grows, there is increasing concern about impacts on human health and wildlife conservation. Effective management of dog populations requires reliable information on their diet, feeding behavior, and social ecology. Free-ranging dogs are reliant on humans, but anthropogenic food subsidies, particularly human faeces (i.e., coprophagy have not previously been fully quantified. In this study we assess the contributions of different food types to the diet, and their influences on the social behaviour of free-ranging dogs in communal lands of rural Zimbabwe, with a focus on coprophagy. Free-ranging dog diets, body condition, and sociology were studied amongst 72 dogs over 18 months using scat analysis and direct observations. Human faeces constituted the fourth most common item in scats (56% occurrence and contributed 21% by mass to the observed diet. Human faeces represented a valuable resource because relative to other food items it was consistently available, and of higher nutritional value than ‘sadza’ (maize porridge, the human staple and primary human-derived food, yielding 18.7% crude protein and 18.7 KJ/kg gross energy, compared to 8.3% and 18.5 KJ/kg for sadza, respectively. Human faeces had protein and energy values equivalent to mammal remains, another important food item. Dog condition was generally good, with 64% of adult females and 74% of adult males in the highest two body condition scores (on a five point scale, suggesting a plentiful and high quality food supply. Dogs largely fed alone, perhaps as a consequence of the small, inert, and spatially dispersed items that comprise their diet, and its abundance. We discuss the relationships between sanitation, human development, the supply of human faeces, female dog fertility, and population control.

Food Security and Staple Crops. Staple Food Around the World

International Nuclear Information System (INIS)

Kilian, Lizette

2012-01-01

Of more than 50,000 edible plant species in the world, only a few hundred contribute significantly to our food supplies. Almost all of the world’s food energy intake is satisfied by just a few crop plants. Rice, maize and wheat make up two-thirds of this already small group of foods. These three grains are the staple foods for more than four billion people both as a source of nutrition and income. A staple crop, by definition, dominates the major part of our diet and supplies a major proportion of our energy and nutrient needs. If staple crops are threatened by drought, pests or nutrient-poor soils, hunger and poverty can rise dramatically.

1993-12-31

Disposal of solid wastes in the food processing industry causes problems. Constant utilization as animal food is not guaranteed any longer and costs for disposal will increase. Biogas production is an alternative for disposal of brewery wastes. Recent investigations have reduced retention time for hydrolysis and total retention time. Retention time is directly proportional to fermenter size consequently resulting in drastic cost reductions. Yielded energy can be utilized in the production line so that fossil fuel use can be reduced with reductions in carbon dioxide emissions. However, some problems remain: sumptous technology; highly qualified specialists; need to reduce ammonia to prevent inhibition of biogas production; cost of technology.

Food waste has received increasing attention in recent years. As part of their corporate social responsibility strategies, food supply chain actors have started to act towards avoiding and reducing food waste. Based on a literature review, an expert interview study, and example cases, we discuss...... food marketing and the role and responsibility of retail. Food marketing and retailing contribute to consumer-related food waste via decisions on date labeling, packaging sizes and design elements, and pricing strategies encouraging overpurchase, as well as communication shifting consumer priorities...... to the disadvantage of food waste avoidance. Potential actions to tackle food waste relate to improved packaging and information, altering pricing strategies, and cooperation with other actors across the supply chain. Three cases highlight the extent to which moral and strategic motives are interlinked...

The difficulty is that as we go into the Space Station world, the cost, effort, hardware, food trash, and food waste that the food service system will generate (which is quite tolerable on a 7 day mission), probably will be intolerable on a 90 day Space Station mission. The challenge in the food service supply is not so much packaging but systems engineering. The big constraints are in the supply pipeline. Those constraints and the possible tradeoffs are discussed.

The paper deals with the evaluation of the total mutagenic activity of samples of the inorganic and organic fractions of three technology smoked sausages (boiled-smoked, semi-smoked, and raw-smoked) and some food additives used to manufacture the above sausages. Their mild and moderate mutagenic effects were recorded in a Salmonella typhimurium bacterial test system with a metabolic activation system. Physicochemical analysis of the fractions of the smoked sausages has shown that their study samples are substantially contaminated with heavy metals and representatives of polycyclic aromatic hydrocarbons, partially causing the mutagenic effects observed.

Wintering Black Ducks (Anas rubripes) concentrate in wetlands along the Atlantic coast where natural and anthropogenic disturbances have increased over the last 50 years, a period in which the population of Black Ducks has declined. We studied the sensitivity of Black Ducks to perturbations in food supply that often result from disturbances by storms, predators, and people. In the paper, we characterize the responses of captive Black Ducks to shifts in food quality and availability during winter and apply those measures to a comparison of wild birds. Captive ducks that were fed intermittently (3 consecutive days/week) compensated for fasted days to achieve similar body mass and body fat to control birds that were fed every day on both animal- and plant-based diets. However, birds that were fed intermittently expended 15% more energy each day than controls when both groups were fed (536 vs. 464 kJ/kg 0.75 ), which indicates that variable food supply increases the costs of maintenance and thus reduces the number of birds that can be supported on the same resource of food without interruptions to foraging. Egg production was not affected by diet quality provided in spring or by the frequency of feeding during the preceding winter months. Black Ducks lost body fat through winter in captivity and in the wild. Fat stores of birds in New Jersey were greater than those of birds in Maine (13.3 vs. 8.3% of body mass) in January, which reflected the high energy demands of cold temperatures in Maine. Values for ∂ 15 N were greater in Maine than in New Jersey for both red blood cells and plasma, which indicated a consistent diet of marine invertebrates in Maine. Greater isotopic variation in red blood cells indicated that diets were more diverse in New Jersey than in Maine for both ∂ 15 N (9.7 ± 1.1 vs. 11.2 ± 0.4‰) and for ∂ 13 C (- 15.1 ± 2.2 vs. - 13.8 ± 1.4‰).

Experimentally the transfer of Cesium 137 through the supply line: Daphnia Magna Straus→Lebistes Reticulatus Peters→Anguilla Anguilla L. starting from water at 50μCi/l is studied. In the direct transfer water→organisms, the three links used have a concentration factor comprised between 2 and 4. The organisms retain a maximum of 0,3% of the water's radioactivity. The muscular mass of the eel represents 60% of the animal's total activity. The biological period is close to 400 days indicating that the fixed Cesium is strongly retained. Through the absorption of a contaminated meal, the Lebists, after two days, retain 67% of the activities of the Daphnies and the Eels, after seven days, 39% of the activity of the Guppys. At the end of the experiment, the Eels contaminated by food 3.500. It takes 63 meals for the level of contamination due to food to equal that due to water. The concentration factors measured in situ are always distinctly higher than those obtained in the laboratory. The experiment proves the possibilities of concentration through the food supply line [fr

Pradhan, P.; Reusser, D. E.; Kropp, J. P.

2012-04-01

Food production is an important driver for global change processes such as land use change and green-house-gas emissions. We analyzed a global, long term data set on food consumption per country to identify typical patterns of diets for the last 50 years. From changes in these patterns, we derived food transitions on a global scale. Subsequently we assessed the environmental consequences from green-house-gas (GHG) emission and anthropogenic inputs. More specifically, we applied Self Organizing Maps (SOM) to identify the dietary patterns based on supply of 12 food groups from FAOSTAT dataset for a period 1961-2007. Using the data on energy output/input ratio for crop production and agricultural emission, we estimated fossil energy and GHG emission associated with the diets. We found 16 typical consumption patterns consisting of high, moderate, low and lowest calorie supply with varied food compositions. The high calorie diets are associated with a higher supply of cereals, animal-products, vegetable-oils and sugar-sweeteners featuring a total supply greater than 2800 kcal/cap/day. During the last 50 years, we observed food transitions from lower calories diets to higher calories diets. On the one hand, food transition towards affluent diet, sometime with shortcuts, occurred in developing countries. On the other hand, developed countries increased consumption of fruits and vegetables. Some of the developing countries are also stagnated in the low consumption level during the last 50 years. The high calorie diets also embed higher fossil energy (1800-3500 kcal/cap/day) and are associated with higher GHG emissions (3.7-6.1 kg CO2 eq/cap/day). However, their non-CO2 GHG emission intensities per kilo calorie of food are relatively low. Changes in dietary patterns are a part of the global change processes. Identification of past transitions is way to predict possible future transitions. This in turn supports policy processes and negotiations in the fields of climate

2014-01-01

Sustainability assessment of food supply chains is relevant for global sustainable development. A framework is proposed for analysing fishfood (fish products for direct human consumption) supply chains with local or international scopes. It combines a material flow model (including an ecosystem dimension) of the supply chains, calculation of sustainability indicators (environmental, socio-economic, nutritional), and finally multi-criteria comparison of alternative supply chains (e.g. fates of landed fish) and future exploitation scenarios. The Peruvian anchoveta fishery is the starting point for various local and global supply chains, especially via reduction of anchoveta into fishmeal and oil, used worldwide as a key input in livestock and fish feeds. The Peruvian anchoveta supply chains are described, and the proposed methodology is used to model them. Three scenarios were explored: status quo of fish exploitation (Scenario 1), increase in anchoveta landings for food (Scenario 2), and radical decrease in total anchoveta landings to allow other fish stocks to prosper (Scenario 3). It was found that Scenario 2 provided the best balance of sustainability improvements among the three scenarios, but further refinement of the assessment is recommended. In the long term, the best opportunities for improving the environmental and socio-economic performance of Peruvian fisheries are related to sustainability-improving management and policy changes affecting the reduction industry. Our approach provides the tools and quantitative results to identify these best improvement opportunities. PMID:25003196

The study analyse the convergence of research priorities to development issues especially from the agricultural and food sector in terms of environmental protection and improvement of the business climate, due to weak institutional interconnection devices. Two types of data are used: bibliometric data and a survey of enterprises. Altogether, 1214 and 1708 bibliographic references were generated from WoS and Scopus respectively (from a total of 9146 and 10 557 publications) in Agriculture, Food and Environment for the period 1991- 2015 subject to the condition that the author or at least one of the authors is affiliated to an institution based in Cameroon. A total of 317 agro-food companies were identified from the National Institute enterprise’s census. The overall message is a relative weak convergence between development priorities identified from perceptions over agricultural and food companies and research works expressed in the scientific literature. This reflects the weak link between research institutions (universities, research centers) and professional milieus that shape entrepreneurship (firms, policy makers) for guidance of scientific production.

Dioxin-like compounds (DLCs) are a group of environmental contaminants whose primary route of human exposure occurs via the consumption of fatty foods of animal origin. Recent safety risk assessments conducted by national and international organizations broadly agree that risk management actions should be developed to decrease DLC exposure. Since the mid-1990s, the U.S. Food and Drug Administration (FDA) has tested specific foods with the goal of describing and reducing DLC exposure. In 2001, FDA developed a strategy for DLCs (http://vm.cfsan.fda.gov/{proportional_to}lrd/dioxstra.html) and substantially expanded its dioxin monitoring program to obtain more comprehensive data on background levels of DLCs in specific food and feed samples as well as to identify and reduce pathways of DLC contamination. FDA's dioxin monitoring program analyzes food collected under its Total Diet Study (TDS) and food and feed from targeted sampling. The TDS is FDA's ongoing market basket survey of approximately 280 core foods in the U.S. food supply. FDA targeted sampling collects and analyzes foods suspected of having both higher DLC levels and more variability in those levels than other foods. The contribution of dietary DLCs to overall exposure and the possible introduction of DLCs in animalbased food via the use of particular feed components was recently identified by the National Academy of Sciences Committee on the Implications of Dioxin in the Food Supply and confirmed FDA's approach articulated in its dioxin strategy.

1986-01-01

This paper reports double-blind observations of volunteers who took 35 kinds of irradiated foods as their main diet for 90 days. The subjects consisted of 70 medical students and 8 staff members in the Shanghai Medical University. They were randomly divided into two groups. One group was supplied with irradiated foods, the other acted as controls eating the same food but non-irradiated. The 35 kinds of irradiated foods were grain, meat products, vegetables, fruits, dried fruits etc. The absorbed dose of irradiation from the processed foods varied from 0.1 to 8.0 kGy. The irradiated foods made up 60.3% of the total food intake by weight. Observations during 90 days indicated that the subjects were all pleased with their diets and no adverse effects on their health were seen. Clinical and laboratory examinations included routine blood and urine tests, blood biochemical examinations, hepatic and renal function tests, endocrinological assays, cellular immunity tests, and mutagenetic studies (such as the incidence of polyploid cells, chromosomal structural aberration, rates of sister chromatid-exchanges, micronuclei test, urine Ames' test). These studies showed that the ingestion of these foods are safe for humans

Bacterial food-borne pathogens in Indian food

International Nuclear Information System (INIS)

Bandekar, J.R.

2015-01-01

Food technology and food processing techniques have made tremendous advances in preservation of food and ensuring safety of food by killing food-borne pathogens. In addition to old techniques such as pasteurization, canning, dehydration, fermentation and salting, a number of new techniques such as radiation processing, high pressure technology and pulsed electric field technology are being applied for preservation of food and to ensure food safety. Total Quality Management (TQM) concepts have been developed to take care of food safety from farm to table. Hazard Analysis at Critical Control Points (HACCP) is being applied for mass scale production of food to make food free from pathogens. Despite these advances, food-borne diseases have become one of the most widespread public health problems in the world. About two thirds of all the outbreaks are traced to microbial contaminated food. According to World Health Organization (WHO) estimates, food-borne and waterborne diarrhoeal diseases kill an estimated 2 million people annually, including many children. Food safety is a major concern not only for developing countries but also for the developed countries. A number of factors such as emergence of new food-borne pathogens, development of drug resistance in pathogens, changing life style, globalization of the food supply etc. are responsible for the continuous persistence of food-borne diseases. The food-borne disease outbreaks due to E. coli O157:H7, Listeria monocytogenes, Salmonella and Campylobacter, are responsible for recall of many foods resulting in heavy losses to food industry. Due to consumer demand, a number of Ready-To-Eat (RTE) minimally processed foods are increasingly marketed; however, there is increased risk of foodborne diseases with these products. Food Technology Division of Bhabha Atomic Research Centre, Mumbai, has been working on food-borne bacterial pathogens particularly Salmonella, Campylobacter, Listeria monocytogenes, Vibrio and Aeromonasf

Water is essential for the proper functioning of the body. Even though a recommendation exists for adequate water intake for Koreans, studies identifying actual water intake from all beverages and foods consumed daily in the Korean population are limited. Thus, we estimated total water intake from both beverages and foods and its association with energy intake and eating behaviors in Korean adults. We used a nationally representative sample of 25,122 Korean adults aged ≥19 years, from the Korean National Health and Nutrition Examination Survey 2008–2012. We performed multiple regression analyses, adjusting for sociodemographic and health-related variables to investigate the contribution of overall energy and dietary intakes and eating behaviors to total water intake. The mean total water intake excluding plain water was 1071 g (398 g from beverages and 673 g from foods) and the estimated plain water intake was 1.3 L. Among Korean adults, 82% consumed beverages (excluding plain water) and these beverages contributed to 10% of daily energy intake and 32% of total water intake from beverages and foods. For every 100 kcal/day in energy intake, water intake consumed through beverages and foods increased by 18 g and 31 g, respectively. Water intake from beverages and foods was positively associated with energy from fat and dietary calcium, but inversely associated with energy density and energy from carbohydrates. When there was a 5% increase in energy intake from snacks and eating outside the home, there was an increase in water intake from beverages of 13 g and 2 g, respectively. Increased daily energy intake, the number of eating episodes, and energy intake from snacks and eating outside the home predicted higher water intake from beverages and foods. Our results provide evidence suggesting that various factors, including sociodemographic status, dietary intakes, and eating behaviors, could be important contributors to the water intake of Korean adults.

Americans' consumption of sodium, fat, and saturated fat exceed federally recommended limits for these nutrients and has been identified as a preventable leading cause of hypertension and cardiovascular disease. More than 40% of the Bronx population comprises African-Americans, who have increased risk and earlier onset of hypertension and are also genetically predisposed to salt-sensitive hypertension. This study analyzed nutrition information for packaged foods advertised in Bronx-based supermarket circulars. Federally recommended limits for sodium, saturated fat and total fat contents were used to identify foods that were high in these nutrients. The proportion of these products with respect to the total number of packaged foods was calculated. More than a third (35%) and almost a quarter (24%) of the 898 advertised packaged foods were high in saturated fat and sodium respectively. Such foods predominantly included processed meat and fish products, fast foods, meals, entrees and side dishes. Dairy and egg products were the greatest contributors of high saturated fat. Pork and beef products, fast foods, meals, entrees and side dishes had the highest median values for sodium, total fat and saturated fat content. The high proportion of packaged foods that are high in sodium and/or saturated fat promoted through supermarket circulars highlights the need for nutrition education among consumers as well as collaborative public health measures by the food industry, community and government agencies to reduce the amounts of sodium and saturated fat in these products and limit the promotion of foods that are high in these nutrients.
Food irradiation - now

Food irradiation technology in South Africa is about to take its rightful place next to existing food preservation methods in protecting food supplies. This is as a result of several factors, the most important of which is the decision by the Department of Health and Population Development to introduce compulsory labelling of food irradiation. The factors influencing food irradiation technology in South Africa are discussed

Trade in agricultural commodities has created increasingly complex linkages between resource use and food supplies across national borders. Understanding the degree to which food production and consumption relies on trade is vital to understanding how to sustainably meet growing food demands across scales. We use detailed bilateral trade statistics and data on agricultural management to examine the land use and water consumption embodied in agricultural trade, which we relate to basic nutritional indicators to show how trade contributes to food availability worldwide. Agricultural trade carries enough calories to provide >1.7 billion people a basic diet each year. We identify key commodities and producer-consumer relationships that disproportionately contribute to embodied resource use and flows of food nutrition at the global scale. For example, just 15 disproportionately large soybean trades comprised ~10% the total harvested area embodied in export production. We conclude by framing these results in terms of the fraction of each country's food production and consumption that is linked to international trade. These findings help to characterize how countries allocate resources to domestic versus foreign food demand.

The extent of industrial trans fatty acids (TFA) in the food supply is unknown in Malaysia, whilst TFA disclosure on food labels is not mandatory by Malaysian food standards. Supermarket foods such as dairy products, fats and oils, meat products, snack foods, soups, and confectionery are commonly cited to be major contributors of TFA in the diet. A consumer survey (n = 622) was used to develop a food listing of these 'high risk' foods. TFA content of high-risk foods were analysed by gas chromatography. Food samples (n = 158) were analysed and their total TFA content were compared with Malaysian Food Standards. A wide variation in TFA content within food categories was indicated. Of the foods containing TFA, many food labels did not cite TFA content or the use of partially hydrogenated vegetable oils (PHVO) as an ingredient. Hypothesised estimates of TFA intake from these supermarket foods in a sample day's menu providing 2000 kcal projected a minimum intake of 0.5 g and a maximum intake of 5.2 g TFA. This study found there was no voluntary disclosure of TFA content on food labels or identifying PHVO as an ingredient. It appears that health education targeting consumers to minimise TFA consumption is required supported by mandatory PHVO disclosure on the food label.

Food waste can be an environmental and economic problem if not managed properly but it can meet various demands of a country if it is considered as a resource. The purpose of this report is to review the existing state of the field in Turkey and identify the potential of food waste as a resource. Food loss and waste (FLW) was examined throughout the food supply chain (FSC) and quantified using the FAO model. Edible FLW was estimated to be approximately 26milliontons/year. The amount of biodegradable waste was estimated based on waste statistics and research conducted on household food waste in Turkey. The total amount of biodegradable waste was found to be approximately 20milliontons/year, where more than 8.6milliontons/year of this waste is FLW from distribution and consumption in the FSC. Options for the end-of-life management of biodegradable wastes are also discussed in this review article. Copyright © 2017 Elsevier Ltd. All rights reserved.

Animals neither negotiate verbally nor conclude binding contracts, but nevertheless regularly exchange goods and services without overt coercion and manage to arrive at agreements over exchange rates. Biological market theory predicts that such exchange rates fluctuate according to the law of supply and demand. Previous studies showed that primates pay more when commodities become scarcer: subordinates groomed dominants longer before being tolerated at food sites in periods of shortage; females groomed mothers longer before obtaining permission to handle their infants when there were fewer newborns and males groomed fertile females longer before obtaining their compliance when fewer such females were present. We further substantiated these results by conducting a 2-step experiment in 2 groups of free-ranging vervet monkeys in the Loskop Dam Nature Reserve, South Africa. We first allowed a single low-ranking female to repeatedly provide food to her entire group by triggering the opening of a container and measured grooming bouts involving this female in the hour after she made the reward available. We then measured the shifts in grooming patterns after we added a second food container that could be opened by another low-ranking female, the second provider. All 4 providers received more grooming, relative to the amount of grooming they provided themselves. As biological market theory predicts, the initial gain of first providers was partially lost again after the introduction of a second provider in both groups. We conclude that grooming was fine-tuned to changes in the value of these females as social partners.

Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants added to plastics, polyurethane foam, electronics, textiles, and other products. These products release PBDEs into the indoor and outdoor environment, thus causing human exposure through food and dust. This study models PBDE dose distributions from ingestion of food for Irish adults on congener basis by using two probabilistic and one semi-deterministic method. One of the probabilistic methods was newly developed and is based on summary statistics of food consumption combined with a model generating realistic daily energy supply from food. Median (intermediate) doses of total PBDEs are in the range of 0.4-0.6 ng/kg(bw)/day for Irish adults. The 97.5th percentiles of total PBDE doses lie in a range of 1.7-2.2 ng/kg(bw)/day, which is comparable to doses derived for Belgian and Dutch adults. BDE-47 and BDE-99 were identified as the congeners contributing most to estimated intakes, accounting for more than half of the total doses. The most influential food groups contributing to this intake are lean fish and salmon which together account for about 22-25% of the total doses.

Full Text Available Purpose. The goal is to optimize a structure of Matlab-model of the three-phase energy supply system with power active filter. The mathematical model that describes the energy supply system modes of operation which contains additional losses is proposed. Methodology. We have applied concepts of the electrical circuits theory, mathematical modeling elements based on linear algebra and vector calculus, mathematical simulation in Matlab package. Results. We have developed two models of three-phase energy supply system. The first one is based on a vector representation, and the second one on the matrix representation of energy processes. Using these models we have solved the problem of maintaining unchanged the average useful power for 279 cases of energy supply system modes of operation. Originality. We have developed methods of mathematical analysis of a three-phase energy supply systems with polyharmonic voltages and currents in the symmetric and asymmetric modes. Practical value. We have created Matlab-model of a three-phase energy supply system with automated calculation of a correction factor. It allows reducing more than one order the time for energy processes elucidation in multiphase systems.
Functional foods and urban agriculture: two responses to climate change-related food insecurity.

Dixon, Jane M; Donati, Kelly J; Pike, Lucy L; Hattersley, Libby

2009-01-01

Affluent diets have negative effects on the health of the population and the environment. Moreover, the ability of industrialised agricultural ecosystems to continue to supply these diets is threatened by the anticipated consequences of climate change. By challenging the ongoing supply the diets of affluent countries, climate change provides a population and environmental health opportunity. This paper contrasts two strategies for dealing with climate change-related food insecurity. Functional foods are being positioned as one response because they are considered a hyper-efficient mechanism for supplying essential micronutrients. An alternative response is civic and urban agriculture. Rather than emphasising increased economic or nutritional efficiencies, civic agriculture presents a holistic approach to food security that is more directly connected to the economic, environmental and social factors that affect diet and health.

2017-09-01

Full Text Available This paper examines the dynamics of food supply per capita and undernourishment in Sub-Saharan Africa SSA for a panel of 42 countries. The dataset was constructed from the FAO and the World Bank global databases for four rounds in five-year intervals. Ordinal measures of national food supply status were generated from daily calorie supply per capita of SSA countries. Regional and inter-temporal dynamics of food supply status very low low medium transition rates and the associated forces underpinning this dynamic process were analyzed and stylized by parametric and non-parametric measures. Economic and socio-demographic factors and regional heterogeneities determining the dynamics of food supply situation in SSA were identified by random-effects ordered probit model. The empirical findings indicate that the food supply level of SSA countries was enhanced by agricultural production and industrial value added as a proxy for structural transformation. However it was adversely affected by military expenditure inflation level of consumer prices proportion of rural population age dependency ratio and regional heterogeneities. The likelihood of SSA countries to face incidence of very low low and medium calorie per capita supply was 23 percent 61 percent and 16 percent respectively. To improve the level of food supply per capita and thereby to reduce food poverty situation SSA countries and other stakeholders need to focus on policies designed to enhance economic growth through agricultural production creation of employment opportunities with structural transformation enhancing health care services improving their demographic structure through family planning and controlling national and regional shocks and instabilities.

Coupled ecosystem/supply chain modelling of fish products from sea to shelf: the Peruvian anchoveta case.

Directory of Open Access Journals (Sweden)

Angel Avadí

Full Text Available Sustainability assessment of food supply chains is relevant for global sustainable development. A framework is proposed for analysing fishfood (fish products for direct human consumption supply chains with local or international scopes. It combines a material flow model (including an ecosystem dimension of the supply chains, calculation of sustainability indicators (environmental, socio-economic, nutritional, and finally multi-criteria comparison of alternative supply chains (e.g. fates of landed fish and future exploitation scenarios. The Peruvian anchoveta fishery is the starting point for various local and global supply chains, especially via reduction of anchoveta into fishmeal and oil, used worldwide as a key input in livestock and fish feeds. The Peruvian anchoveta supply chains are described, and the proposed methodology is used to model them. Three scenarios were explored: status quo of fish exploitation (Scenario 1, increase in anchoveta landings for food (Scenario 2, and radical decrease in total anchoveta landings to allow other fish stocks to prosper (Scenario 3. It was found that Scenario 2 provided the best balance of sustainability improvements among the three scenarios, but further refinement of the assessment is recommended. In the long term, the best opportunities for improving the environmental and socio-economic performance of Peruvian fisheries are related to sustainability-improving management and policy changes affecting the reduction industry. Our approach provides the tools and quantitative results to identify these best improvement opportunities.
Quantifying Postharvest Loss and the Implication of Market-Based Decisions: A Case Study of Two Commercial Domestic Tomato Supply Chains in Queensland, Australia

Directory of Open Access Journals (Sweden)

Tara J. McKenzie

2017-08-01

Full Text Available Abstract: Using a multi-disciplinary approach, this study quantifies horticultural postharvest losses of two medium-sized (annual pack volume 4500 t commercial, domestic, tomato supply chains. Quantification of loss was based on weight or volume, consistent with direct measurement methods of the Food Loss and Waste Accounting and Reporting Standard 2016 and qualitative techniques were used to identify the drivers of the loss and contextualise the findings. Postharvest loss was found to be between 40.3% (55.34 t and 55.9% (29.61 t of the total harvestable product. It was determined that between 68.6% and 86.7% of undamaged, edible, harvested tomatoes were rejected as outgrades and consequently discarded due to product specifications. Between 71.2% and 84.1% of produced tomatoes were left in the field and not harvested. This study highlights significant factors contributing to high levels of food loss and waste. Edible products are being removed from the commercial food supply chain, rejected as outgrades deemed cosmetically defective due to market-based decisions. With only 44.1% and 59.7% of the harvestable crop reaching the consumers of the two supply chains, respectively, it is perhaps more appropriate to describe a food “waste” chain as opposed to a food “supply” chain.

Consumer-perceived quality in 'traditional' food chains: the case of the Greek meat supply chain.

Science.gov (United States)

Krystallis, Athanassios; Chryssochoidis, George; Scholderer, Joachim

2007-01-01

Recent food scares have increased consumer concern about meat safety. However, the Greek 'traditional' meat supply chain from producers to local butchers does not seem to realise the pressing consumer demand for certified meat quality. Or is it that, in such food chains, this demand is not so pressing yet? The present paper seeks to answer this question based on a survey conducted in the Athens area, involving a sample of 268 participants responsible for food purchasing decisions. The survey mainly aims to develop an integrated model of factors that affect consumer-perceived meat quality and to develop the profile of different consumer segments in relation to these perceptions. The substantial findings of the survey include the fact that, despite their enormous per capita consumption, the majority of consumers are not particularly involved in the meat-purchasing process. Rather they attach importance to visual intrinsic quality cues evaluated in a pre-purchasing context. In this respect, intrinsic quality cues are assigned a role similar to that of quality certification; coupled with the choice of traditional channels and the resulting personal relation with the butcher, they can be understood as efforts to decrease risk of the purchasing decision. Moreover, consumers with such behaviour seem to relate domestic country of origin of meat mostly with perceptions of general safety. Finally, a small, but promising trend with substantial marketing implications of frequent purchases of chicken and pork at supermarkets should not be ignored.

Nutrient intake was surveyed by the total food duplicate method in 49 adult ethnically Malay women (at the ages of 18 to 47 years and mostly at 30-39 years) working in Kuala Lumpur, Malaysia. Simultaneously, hematological examinations, serum biochemistry, anthropometry and clinical examination were conducted. Nutrient intakes were estimated in reference to the weight of each food item and the standard food composition tables. Lunch was the most substantial meal of the day with rice as a staple food. Compared with the Recommended Dietary Allowance (RDA) values, daily intakes of energy (1,917 kcal as an arithmetic mean), protein (62.2 g), vitamin B1 (0.83 mg) and vitamin B2 (1.18 mg) were sufficient, but intakes of minerals [i.e., calcium (347.8 mg) and iron (12.5 mg)] and some vitamins [i.e., vitamin A (equivalent to 627 micrograms retinol) and niacin (7.84 mg)] were less than RDA. When evaluated on an individual basis, the prevalence of those who took less than 80% RDA was highest for iron (92%), followed by niacin (80%), calcium (57%) and vitamin A (57%). The presence of 7 hypohemoglobinemia cases may be related to the insufficient iron intake. Overweight cases (14 women) were also detected, the prevalence of which increased at advanced ages. Lipid intake was rather high (28% of total food on energy basis), for which the major source was plants with limited contribution from fish/shellfish.

Four different enzyme treatments-conjugase alone, conjugase and alpha-amylase, conjugase and Pronase reg-sign and a triple enzyme combination of conjugase, Pronase reg-sign and alpha-amylase were applied in the extraction of total folate from infant formula, baby foods and various other foods by microbiological and radioassay methods. Significant increases (P < 0.05) in measurable folate were obtained using the triple enzyme system in spinach, Camembert cheese, soy-based infant formula and cereal-based, meat-based and fruit-based infant foods over the use of conjugase alone by the microbiological method. Increases were also observed in many of the same foods using Pronase reg-sign or alpha-amylase in addition to conjugase alone. Increases obtained by microbiological assay were confirmed by radioassay in a number of foods studied

In Belém city is located the potable water supply system of its metropolitan area, which includes, in addition to this city, four more municipalities. In this water supply complex is the Água Preta lake, which serves as a reservoir for the water pumped from the Guamá river. Due to the great importance of this lake for this system, several works have been devoted to its study, from the monitoring of the quality of its waters to its hydrodynamic modeling. This paper presents the results obtained by computer simulation of the phosphorus dispersion within this reservoir by the numerical solution of two-dimensional equation of advection-diffusion-reaction by the method θ/SUPG. Comparing these results with data concentration of total phosphorus collected from November 2008 to October 2009 and from satellite photos show that the biggest polluters of the water of this lake are the domestic sewage dumps from the population living in its vicinity. The results obtained indicate the need for more information for more precise quantitative analysis. However, they show that the phosphorus brought by the Guamá river water is consumed in an area adjacent to the canal that carries this water into the lake. Phosphorus deposits in the lake bottom should be monitored to verify their behavior, thus preventing the quality of water maintained therein.

2016-11-01

An optimized flow injection hydride generation atomic absorption spectroscopy (FI-HGAAS) method was used to determine total arsenic in selected food samples (beef, chicken, fish, milk, cheese, egg, rice, rice-based products, wheat flour, corn flour, oats, breakfast cereals, legumes and potatoes) and to estimate their contributions to inorganic arsenic dietary intake. The limit of detection (LOD) and limit of quantification (LOQ) values obtained were 6μgkg(-)(1) and 18μgkg(-)(1), respectively. The mean recovery range obtained for all food at a fortification level of 200μgkg(-)(1) was 85-110%. Accuracy was evaluated using dogfish liver certified reference material (DOLT-3 NRC) for trace metals. The highest total arsenic concentrations (in μgkg(-)(1)) were found in fish (152-439), rice (87-316) and rice-based products (52-201). The contribution to inorganic arsenic (i-As) intake was calculated from the mean i-As content of each food (calculated by applying conversion factors to total arsenic data) and the mean consumption per day. The primary contributors to inorganic arsenic intake were wheat flour, including its proportion in wheat flour-based products (breads, pasta and cookies), followed by rice; both foods account for close to 53% and 17% of the intake, respectively. The i-As dietary intake, estimated as 10.7μgday(-)(1), was significantly lower than that from drinking water in vast regions of Argentina. Copyright © 2016 Elsevier Ltd. All rights reserved.

In order to increase the efficiency of anaerobic digestion, it is necessary to understand the role of the total solids content on the behavior of the microbial communities involved in anaerobic digestion of organic matter from wet to dry technology. The performances of mesophilic anaerobic digestion of food waste with different total solids contents from 5% to 20% were compared and the microbial communities in reactors were investigated using 454 pyrosequencing technology. Three stable anaerobic digestion processes were achieved for food waste biodegradation and methane generation. Better performances mainly including volatile solids reduction and methane yield were obtained in the reactors with higher total solids content. Pyrosequencing results revealed significant shifts in bacterial community with increasing total solids contents. The proportion of phylum Chloroflexi decreased obviously with increasing total solids contents while other functional bacteria showed increasing trend.

Slow food, fast food and the control of food intake.

Science.gov (United States)

de Graaf, Cees; Kok, Frans J

2010-05-01

This Perspective focuses on two elements of our food supply and eating environment that facilitate high energy intake: a high eating rate and distraction of attention from eating. These two elements are believed to undermine our body's capacity to regulate its energy intake at healthy levels because they impair the congruent association between sensory signals and metabolic consequences. The findings of a number of studies show that foods that can be eaten quickly lead to high food intake and low satiating effects-the reason being that these foods only provide brief periods of sensory exposure, which give the human body insufficient cues for satiation. Future research should focus on the underlying physiological, neurological and molecular mechanisms through which our current eating environment affects our control of food intake.
Polychaete response to fresh food supply at organically enriched coastal sites: Repercussion on bioturbation potential and trophic structure

Venturini, N.; Pires-Vanin, A. M. S.; Salhi, M.; Bessonart, M.; Muniz, P.

2011-12-01

We investigated the vertical distribution, abundance, specific and functional structure of polychaete assemblages at four organically enriched sites. The effects of fresh organic matter input from the water column driving by upwelling were evaluated. Temperature and salinity values indicate the intrusion of South Atlantic Central Water (SACW) in spring, a nutrient-rich water mass. The dominance of the conveyor belt transport (CONV) in the station influenced by SACW, in the spring survey, is associated with fresh organic matter input as indicated by higher amounts of polyunsaturated fatty acids. Conversely, the predominance of the diffusive mixing (DIFF) bioturbation category, in the sites without SACW influence is related to the preferential accumulation of more refractive food resources as indicated by higher concentrations of short chain saturated fatty acids. At the site influenced by SACW, the changes in polychaete assemblages were not all evident during proceeding upwelling conditions, but may persist at the end of the upwelling. Polychaetes in the study area seemed to be limited by the quality but not the quantity of food. The delay in polychaete response to fresh food supply may be related to the organic enrichment and the prevalence of refractory material in the sediments.

Full Text Available Maintaining collaboration among the entire stages in the agri-food supply chain to achieve sustainability is complex. All the stakeholders involved in the activities have to prioritize their financial benefits without putting aside social development and environmental responsibilities. Some scholars have paid attention to this topic. The objective of this paper is to review current research on sustainable supply chain and collaboration model in agri-food industry. Sustainability aspects that consist of economic, environment, and social and the model of sustainable supply chain in agri-food industry are analyzed. Moreover, collaboration in sustainable agri-food supply chain management is also studied thoroughly from vertical and horizontal perspectives. The result shows that there are few studies focusing on the integrated collaboration to achieve sustainable supply chain system. Additionally, not all sustainable aspects are covered thoroughly. The scholars pays more attention to economic and environmental aspects than social aspects. Furthermore, some studies only focus on one type of collaboration in sustainable agri-food supply chain. Often, these studies do not even consider all elements in the triple bottom line.

Food allergy is an increasing problem for those affected, their families or carers, the food industry and for regulators. The food supply chain is highly vulnerable to fraud involving food allergens, risking fatalities and severe reputational damage to the food industry. Many facets are being pursued to ameliorate the difficulties including better food labelling and the concept of thresholds of elicitation of allergy symptoms as risk management tools. These efforts depend to a high degree on the ability reliably to detect and quantify food allergens; yet all current analytical approaches exhibit severe deficiencies that jeopardise accurate results being produced particularly in terms of the risks of false positive and false negative reporting. If we fail to realise the promise of current risk assessment and risk management of food allergens through lack of the ability to measure food allergens reproducibly and with traceability to an international unit of measurement, the analytical community will have failed a significant societal challenge. Three distinct but interrelated areas of analytical work are urgently needed to address the substantial gaps identified: (a) a coordinated international programme for the production of properly characterised clinically relevant reference materials and calibrants for food allergen analysis; (b) an international programme to widen the scope of proteomics and genomics bioinformatics for the genera containing the major allergens to address problems in ELISA, MS and DNA methods; (c) the initiation of a coordinated international programme leading to reference methods for allergen proteins that provide results traceable to the SI. This article describes in more detail food allergy, the risks of inapplicable or flawed allergen analyses with examples and a proposed framework, including clinically relevant incurred allergen concentrations, to address the currently unmet and urgently required analytical requirements.

A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7-69 years) from the Dutch National Food Consumption Survey 2007-2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE), free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of sugar guidelines was not strongly associated with higher diet quality in adults.

Is irradiation of food stuffs safe?

International Nuclear Information System (INIS)

Maheshwari, Raaz K.; Yadav, Rajesh K.

2014-01-01

Many advanced and several developing countries have abundant supplies of fresh, safe and nutritious food stuffs. Yet, despite the many precautions and processes in place to ensure safe food supply, microbial contamination is still a concern. There are a number of food processing tools available that provide additional protection for the food we consume. One very promising tool is food irradiation, which is a process of imparting ionizing energy to food to kill microorganisms. Food irradiation is the process of exposing food to a controlled source of ionising radiation for the purposes of reduction of microbial Ioad, destruction of pathogens, extension of product shelf life, and/or disinfection of produce. The term irradiation often evokes fears of nuclear radioactivity and cancer among consumers. The process seems frightening because it is powerful and invisible. Consequently questions and concerns exist particularly about the safety or wholesomeness of irradiated food. The paper highlights food irradiation as a food safety measure and the issues of concerns for consumers. (author)

Spices, such as cinnamon, cloves, cardamom, garlic, ginger, cumin, coriander and turmeric are used all over the world as flavouring and colouring ingredients in Indian foods. Previous studies have shown that spices contain variable amounts of total oxalates but there are few reports of soluble oxalate contents. In this study, the total, soluble and insoluble oxalate contents of ten different spices commonly used in Indian cuisine were measured. Total oxalate content ranged from 194 (nutmeg) to 4,014 (green cardamom) mg/100 g DM, while the soluble oxalate contents ranged from 41 (nutmeg) to 3,977 (green cardamom) mg/100 g DM. Overall, the percentage of soluble oxalate content of the spices ranged from 4.7 to 99.1% of the total oxalate content which suggests that some spices present no risk to people liable to kidney stone formation, while other spices can supply significant amounts of soluble oxalates and therefore should be used in moderation.

However,after a long time fighting food shortages,China became self-sufficient in food in 1995. At this time, the country began for the first time to regulate food safety. Yet China has still not established a legal systern efficient in ensuring this safety. Many problems are rooted in the administration regime and China's priority of economic development.
Animal health and price transmission along livestock supply chains.

Science.gov (United States)

Aragrande, M; Canali, M

2017-04-01

Animal health diseases can severely affect the food supply chain by causing variations in prices and market demand. Price transmission analysis reveals in what ways price variations are transmitted along the supply chain, and how supply chains of substitute products and different regional markets are also affected. In perfect markets, a price variation would be completely and instantaneously transmitted across the different levels of the supply chain: producers, the processing industry, retailers and consumers. However, empirical studies show that food markets are often imperfect, with anomalies or asymmetries in price transmission and distortions in the distribution of market benefits. This means, for instance, that a price increase at the consumer level may not be transmitted from retailers to processors and producers; yet, on the other hand, price falls may rapidly affect the upstream supply chain. Market concentration and the consequent exertion of market power in key segments of the supply chain can explain price transmission asymmetries and their distributional effects, but other factors may also be involved, such as transaction costs, scale economies, and imperfect information. During the bovine spongiform encephalopathy (BSE) crisis, asymmetric price transmission in the beef supply chain and related meat markets determined distributional effects among sectors. After the spread of the BSE food scare, the fall in demand marginally affected the price paid to retailers, but producers and wholesalers suffered much more, in both price reductions and the time needed to recover to precrisis demand. Price transmission analysis investigates how animal health crises create different economic burdens for various types of stakeholder, and provides useful socioeconomic insights when used with other tools.

Hawkes, C

2008-03-01

Taking a food supply chain approach, this paper examines the regulation of food marketing and nutrition labelling as strategies to help combat obesity in China in an era of rapid agro-food industry growth. China is the largest food producer and consumer in the world. Since the early 1980s, the agro-food industry has undergone phenomenal expansion throughout the food supply chain, from agricultural production to trade, agro-food processing to food retailing, and from food service to advertising and promotion. This industry growth, alongside related socioeconomic changes and government policies, has encouraged a 'nutrition transition'. China's population, especially in urban areas, is now consuming significantly more energy from dietary fat, which is leading to higher rates of obesity. Regulation of food advertising and promotion and nutrition labelling has the potential to help prevent the further growth of obesity in China and encourage the agro-food industry to supplier healthier foods. Government legislation and guidance, as well as self-regulation and voluntary initiatives, are needed to reduce children's exposure to food advertising and promotion, and increase the effectiveness of nutrition labelling. Policies on food marketing and nutrition labelling should be adapted to the China context, and accompanied by further action throughout the food supply chain. Given China's unique characteristics and position in the world today, there is an opportunity for the government and the agro-food industry to lead the world by creating a balanced, health promoting model of complementary legislation and industry action.

Corner stores are part of the urban food environment that may contribute to obesity and diet-related diseases, particularly for low-income and minority children. The snack foods available in corner stores may be a particularly important aspect of an urban child's food environment. Unfortunately, there is little data on exactly what snack foods corner stores stock, or where these foods come from. We evaluated snack foods in 17 Philadelphia corner stores, located in three ethnically distinct, low-income school neighborhoods. We recorded the manufacturer, calories, fat, sugar, and sodium for all snack items, excluding candy and prepared foods. We then compared the nutritive content of assessed snack items to established dietary recommendations and a school nutrition standard. In total, stores stocked 452 kinds of snacks, with only 15% of items common between all three neighborhoods. Total and unique snacks and snack food manufacturers varied by neighborhood, but distributions in snack type varied negligibly: overall, there were no fruit snacks, no vegetable snacks, and only 3.6% of all snacks (by liberal definition) were whole grain. The remainder (96.4% of snacks) was highly processed foods. Five of 65 manufacturers supplied 73.4% of all kinds of snack foods. Depending on serving size definition, 80.0-91.5% of snack foods were "unhealthy" (by the school nutrition standard), including seven of 11 wholegrain products. A single snack item could supply 6-14% of a day's recommended calories, fat, sugar, and sodium on average (or 56-169% at the extreme) for a "typical" child. We conclude that corner store snack food inventories are almost entirely unhealthful, and we discuss possible implications and next steps for research and intervention.

Full Text Available The relationships between the perceptions and practical implementation of food safety regulations by food suppliers in Taiwan were evaluated. A questionnaire survey was used to identify individuals who were full-time employees of the food supply industry with at least 3 months of experience. Dimensions of perceptions of food safety regulations were classified using the constructs of attitude of employees and corporate concern attitude for food safety regulation. The behavior dimension was classified into employee behavior and corporate practice. Food suppliers with training in food safety were significantly better than those without training with respect to the constructs of perception dimension of employee attitude, and the constructs of employee behavior and corporate practice associated with the behavior dimension. Older employees were superior in perception and practice. Employee attitude, employee behavior, and corporate practice were significantly correlated with each other. Satisfaction with governmental management was not significantly related to corporate practice. The corporate implementation of food safety regulations by suppliers was affected by employees' attitudes and behaviors. Furthermore, employees' attitudes and behaviors explain 35.3% of corporate practice. Employee behavior mediates employees' attitudes and corporate practices. The results of this study may serve as a reference for governmental supervision and provide training guidelines for workers in the food supply industry.

In 2000, the Consumer Goods Forum established the Global Food Safety Initiative (GFSI) to increase the safety of the world's food supply and to harmonize food safety regulations worldwide. In 2013, a university research team in conjunction with Diversey Consulting (Sealed Air), the Consumer Goods Forum, and officers of GFSI solicited input from more than 15,000 GFSI-certified food producers worldwide to determine whether GFSI certification had lived up to these expectations. A total of 828 usable questionnaires were analyzed, representing about 2,300 food manufacturing facilities and food suppliers in 21 countries, mainly across Western Europe, Australia, New Zealand, and North America. Nearly 90% of these certified suppliers perceived GFSI as being beneficial for addressing their food safety concerns, and respondents were eight times more likely to repeat the certification process knowing what it entailed. Nearly three-quarters (74%) of these food manufacturers would choose to go through the certification process again even if certification were not required by one of their current retail customers. Important drivers for becoming GFSI certified included continuing to do business with an existing customer, starting to do business with new customer, reducing the number of third-party food safety audits, and continuing improvement of their food safety program. Although 50% or fewer respondents stated that they saw actual increases in sales, customers, suppliers, or employees, significantly more companies agreed than disagreed that there was an increase in these key performance indicators in the year following GFSI certification. A majority of respondents (81%) agreed that there was a substantial investment in staff time since certification, and 50% agreed there was a significant capital investment. This survey is the largest and most representative of global food manufacturers conducted to date.
Alternative Food Preservation Techniques, New Technology in Food Preparation and Appropriateness of Food Supply for the Permanently Manned Space Station

Science.gov (United States)

Whelan, R. H.

1985-01-01

Alternative food preservation techniques are defined as unique processes and combinations of currently used processes for food preservation. Food preservation is the extension of the useful shelf-life of normally perishable foods (from harvest to final consumption) by controlling micro-organisms, enzymes, chemical changes, changes in sensory characteristics and the prevention of subsequent recontamination. The resulting products must comply with all applicable food manufacturing practice regulations and be safe. Most of the foods currently used in both space and military feeding are stabilized either by dehydration or the use of a terminal sterilization process. Other available options would be formulation to reduce water activity, the refrigeration and freezing of perishable foods, chemical addition, and physical treatment (ionizing or nonionizing radiation or mechanical action). These alternatives are considered and proposals made.
The Coalition for Sustainable Egg Supply project: An introduction.

2015-03-01

In the United States, empirical information on the sustainability of commercial-scale egg production is lacking. The passage of state regulations specific to hen housing created urgency to better understand the effects of different housing systems on the sustainability of the egg supply, and stimulated the formation of a coalition, the Coalition for a Sustainable Egg Supply (CSES), to conduct research on this topic. The CSES is a multi-stakeholder group with 27 members, including food manufacturers, research institutions, scientists, restaurants, food service, retail food companies, egg suppliers, and nongovernmental organizations. A commercial-scale study was developed to better understand the effect of 3 housing systems (conventional cage, enriched colony, and cage-free aviary) on 5 areas related to a sustainable egg supply. These 5 sustainability areas represent effects on people, animals, and the environment: animal health and well-being, environment, food safety, worker health and safety, and food affordability. Five teams of scientists, each associated with a sustainability area, conducted an integrated field study at a commercial site in the upper Midwest through 2 flock cycles in 3 housing systems. This paper provides a brief overview of the CSES project to serve as an introduction for the papers that follow in this volume of Poultry Science. © The Author 2015.

Adjusting energy expenditures to energy supply: food availability regulates torpor use and organ size in the Chilean mouse-opossum Thylamys elegans.

Science.gov (United States)

Bozinovic, Francisco; Muñoz, José L P; Naya, Daniel E; Cruz-Neto, Ariovaldo P

2007-05-01

We studied how food abundance and consumption regulates torpor use and internal organ size in the Chilean mouse-opossum Thylamys elegans (Dielphidae), a small nocturnal marsupial, endemic in southern South America. We predicted that exposure to food rations at or above the minimum energy levels necessary for maintenance would not lead to any signs of torpor, while reducing food supply to energy levels below maintenance would lead to marked increases in frequency, duration and depth of torpor bouts. We also analyzed the relationship between food availability and internal organ mass. We predicted a positive relationship between food availability and internal organ size once the effect of body size is removed. Animals were randomly assigned to one of two groups and fed either 70, 100 or 130% of their daily energy requirement (DER). We found a positive and significant correlation between %DER and body temperature, and also between %DER and minimum body temperature. In contrast, for torpor frequency, duration and depth, we found a significant negative correlation with %DER. Finally, we found a significant positive correlation between the %DER and small intestine and ceacum dry mass. We demonstrate that when food availability is limited, T. elegans has the capacity to reduce their maintenance cost by two different mechanisms, that is, increasing the use of torpor and reducing organ mass.

Estimated Intakes and Sources of Total and Added Sugars in the Canadian Diet

Directory of Open Access Journals (Sweden)

Tristin D. Brisbois

2014-05-01

Full Text Available National food supply data and dietary surveys are essential to estimate nutrient intakes and monitor trends, yet there are few published studies estimating added sugars consumption. The purpose of this report was to estimate and trend added sugars intakes and their contribution to total energy intake among Canadians by, first, using Canadian Community Health Survey (CCHS nutrition survey data of intakes of sugars in foods and beverages, and second, using Statistics Canada availability data and adjusting these for wastage to estimate intakes. Added sugars intakes were estimated from CCHS data by categorizing the sugars content of food groups as either added or naturally occurring. Added sugars accounted for approximately half of total sugars consumed. Annual availability data were obtained from Statistics Canada CANSIM database. Estimates for added sugars were obtained by summing the availability of “sugars and syrups” with availability of “soft drinks” (proxy for high fructose corn syrup and adjusting for waste. Analysis of both survey and availability data suggests that added sugars average 11%–13% of total energy intake. Availability data indicate that added sugars intakes have been stable or modestly declining as a percent of total energy over the past three decades. Although these are best estimates based on available data, this analysis may encourage the development of better databases to help inform public policy recommendations.

Background The importance of consumer trust in the food supply has previously been identified, and dimensions of consumer trust in food?who they trust and the type of trust that they exhibit?has been explored. However, there is a lack of research about the mechanisms through which consumer trust in the food supply is developed, maintained, broken and repaired. This study seeks to address this gap by exploring if, and how, consumer trust in the food supply is considered by the media, food indu...
Social Interaction and Price Transmission in Multi-Tier Food Supply Chains

Maria Widyarini

2016-06-01

Full Text Available This research focuses on social interaction associated with price transmission in a multi-tier rice supply chain. A case study and qualitative methods are employed to examine a well-established supply network in Karawang District in Indonesia. Farmers and traders used their existing network in selling rice crops to traders and adopted a payment scheme for cash-and-carry transactions. Information on the market situation was obtained through personal interviews and observations including text messaging with farmer and trader informants. Evidence reveals that social relationships are vital in transmitting price information among networked actors to maintain the flow of rice, mitigate risk, and avoid losses due to poor quality of the rice product. Findings show that social interaction enables actors in an end-to-end rice supply chain to deal with the assurance of supply rationing.

The 3–11 Earthquake occurred in Japan last year had greatly damaged the lives and properties and also caused the core meltdown accident in the Fukushima nuclear power plant followed by the leakage of radioactive materials into biosphere. In order to protect against the detriment of radiation from foods which were imported from Japan, the Institute of Nuclear Energy Research (INER) in Taiwan started to conduct radioactivity inspection of food products from Japan after the accident. A total of about 20,000 samples had been tested from March 24 2011 to March 31 2012. - Highlights: • About 20,000 food products imported from Japan were tested by low-background HPGe detectors. • In total, 46 food products had been found to be contaminated by I-131, Cs-134 or Cs-137, however, the radiation levels were all below the limit of Taiwanese regulations. • The measurement techniques described in this study can be used as a fast screening tool to ensure safety of food supplied
Non-CO2 Greenhouse Gas Emissions in China 2012: Inventory and Supply Chain Analysis

Reliable inventory information is critical in informing emission mitigation efforts. Using the latest officially released emission data, which is production based, we take a consumption perspective to estimate the non-CO2 greenhouse gas (GHG) emissions for China in 2012. The non-CO2 GHG emissions, which cover CH4, N2O, HFCs, PFCs, and SF6, amounted to 2003.0 Mt. CO2-eq (including 1871.9 Mt. CO2-eq from economic activities), much larger than the total CO2 emissions in some developed countries. Urban consumption (30.1%), capital formation (28.2%), and exports (20.6%) derived approximately four fifths of the total embodied emissions in final demand. Furthermore, the results from structural path analysis help identify critical embodied emission paths and key economic sectors in supply chains for mitigating non-CO2 GHG emissions in Chinese economic systems. The top 20 paths were responsible for half of the national total embodied emissions. Several industrial sectors such as Construction, Production and Supply of Electricity and Steam, Manufacture of Food and Tobacco and Manufacture of Chemicals, and Chemical Products played as the important transmission channels. Examining both production- and consumption-based non-CO2 GHG emissions will enrich our understanding of the influences of industrial positions, final consumption demands, and trades on national non-CO2 GHG emissions by considering the comprehensive abatement potentials in the supply chains.
A Review on Quantitative Models for Sustainable Food Logistics Management

Directory of Open Access Journals (Sweden)

M. Soysal

2012-12-01

Full Text Available The last two decades food logistics systems have seen the transition from a focus on traditional supply chain management to food supply chain management, and successively, to sustainable food supply chain management. The main aim of this study is to identify key logistical aims in these three phases and analyse currently available quantitative models to point out modelling challenges in sustainable food logistics management (SFLM. A literature review on quantitative studies is conducted and also qualitative studies are consulted to understand the key logistical aims more clearly and to identify relevant system scope issues. Results show that research on SFLM has been progressively developing according to the needs of the food industry. However, the intrinsic characteristics of food products and processes have not yet been handled properly in the identified studies. The majority of the works reviewed have not contemplated on sustainability problems, apart from a few recent studies. Therefore, the study concludes that new and advanced quantitative models are needed that take specific SFLM requirements from practice into consideration to support business decisions and capture food supply chain dynamics.
Dynamics of quality as a strategic variable in complex food supply chain network competition: The case of fresh produce

Science.gov (United States)

Nagurney, Anna; Besik, Deniz; Yu, Min

2018-04-01

In this paper, we construct a competitive food supply chain network model in which the profit-maximizing producers decide not only as to the volume of fresh produce produced and distributed using various supply chain network pathways, but they also decide, with the associated costs, on the initial quality of the fresh produce. Consumers, in turn, respond to the various producers' product outputs through the prices that they are willing to pay, given also the average quality associated with each producer or brand at the retail outlets. The quality of the fresh produce is captured through explicit formulae that incorporate time, temperature, and other link characteristics with links associated with processing, shipment, storage, etc. Capacities on links are also incorporated as well as upper bounds on the initial product quality of the firms at their production/harvesting sites. The governing concept of the competitive supply chain network model is that of Nash Equilibrium, for which alternative variational inequality formulations are derived, along with existence results. An algorithmic procedure, which can be interpreted as a discrete-time tatonnement process, is then described and applied to compute the equilibrium produce flow patterns and accompanying link Lagrange multipliers in a realistic case study, focusing on peaches, which includes disruptions.
The need for multisectoral food chain approaches to reduce trans fat consumption in India.

Downs, Shauna M; Singh, Archna; Gupta, Vidhu; Lock, Karen; Ghosh-Jerath, Suparna

2015-07-22

The World Health Organization (WHO) recommends virtually eliminating trans fat from the global food supply. Although several high-income countries have successfully reduced trans fat levels in foods, low- and middle-income countries such as India face additional challenges to its removal from the food supply. This study provides a systems analysis of the Indian food chain to assess intervention options for reducing trans fat intake in low-income consumers. Data were collected at the manufacturer, retailer and consumer levels. Qualitative interviews were conducted with vanaspati manufacturers (n = 13) and local food vendors (n = 44). Laboratory analyses (n = 39) of street foods/snacks sold by the vendors were also conducted. Trans fat and snack intakes were also examined in low-income consumers in two rural villages (n = 260) and an urban slum (n = 261). Manufacturers of vanaspati described reducing trans fat levels as feasible but identified challenges in using healthier oils. The fat content of sampled oils from street vendors contained high levels of saturated fat (24.7-69.3 % of total fat) and trans fat (0.1-29.9 % of total fat). Households were consuming snacks high in trans fat as part of daily diets (31 % village and 84.3 % of slum households) and 4 % of rural and 13 % of urban households exceeded WHO recommendations for trans fat intakes. A multisectoral food chain approach to reducing trans fat is needed in India and likely in other low- and middle-income countries worldwide. This will require investment in development of competitively priced bakery shortenings and economic incentives for manufacturing foods using healthier oils. Increased production of healthier oils will also be required alongside these investments, which will become increasingly important as more and more countries begin investing in palm oil production.

2016-10-01

Full Text Available In industrialized nations, local food networks have generally been analyzed through alternative food systems, in spite of the fact that they are much more diverse than this would imply. In France, ‘short food chains’ are both a continuation of a long tradition and a recent trend which now extends beyond activists, to consumers and producers as well. This paper will explore the conditions under which these chains can change the practices and knowledge of ordinary actors in urban food systems, from producers to urban consumers and policy-makers, in the area of agriculture and sustainability. It will consider the case study of the creation and development of an urban open-air market which has been analyzed using intervention research with input from economic sociology. We will highlight how personal relations, which are encouraged by a participatory context, support the evolution of practices and knowledge. We will also illustrate how a system of produce labelling has emerged as a mediation resource, and has increased changes as well as participation within the re-territorialization of the urban food system. By describing a concrete expression of food democracy which is spreading in France via a free collective trademark, and by showing its role in the transition of ‘ordinary’ actors towards a more sustainable agriculture, this paper will shine new light onto local food chains as well as traditional short food chains, and will call for more research on the subject.
Lost water and nitrogen resources due to EU consumer food waste

2015-08-01

The European Parliament recently called for urgent measures to halve food waste in the EU, where consumers are responsible for a major part of total waste along the food supply chain. Due to a lack of data on national food waste statistics, uncertainty in (consumer) waste quantities (and the resulting associated quantities of natural resources) is very high, but has never been previously assessed in studies for the EU. Here we quantify: (1) EU consumer food waste, and (2) associated natural resources required for its production, in term of water and nitrogen, as well as estimating the uncertainty of these values. Total EU consumer food waste averages 123 (min 55-max 190) kg/capita annually (kg/cap/yr), i.e. 16% (min 7-max 24%) of all food reaching consumers. Almost 80%, i.e. 97 (min 45-max 153) kg/cap/yr is avoidable food waste, which is edible food not consumed. We have calculated the water and nitrogen (N) resources associated with avoidable food waste. The associated blue water footprint (WF) (the consumption of surface and groundwater resources) averages 27 litre per capita per day (min 13-max 40 l/cap/d), which slightly exceeds the total blue consumptive EU municipal water use. The associated green WF (consumptive rainwater use) is 294 (min 127-max 449) l/cap/d, equivalent to the total green consumptive water use for crop production in Spain. The nitrogen (N) contained in avoidable food waste averages 0.68 (min 0.29-max 1.08) kg/cap/yr. The food production N footprint (any remaining N used in the food production process) averages 2.74 (min 1.02-max 4.65) kg/cap/yr, equivalent to the use of mineral fertiliser by the UK and Germany combined. Among all the food product groups wasted, meat accounts for the highest amounts of water and N resources, followed by wasted cereals. The results of this study provide essential insights and information on sustainable consumption and resource efficiency for both EU policies and EU consumers.

In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.
Food safety in a nuclear crisis: The role of the veterinarian.

Veterinarians are integrally involved in the maintenance of a safe and sufficient food supply; this involvement may be put to the test when a crisis - particularly a nuclear crisis - occurs. Few people can be said to be experts in how to ensure a safe food supply in a nuclear crisis. However, a working knowledge of radionuclides and how they behave in the food system, and the ability to identify high-risk foods and high-risk consumers in a crisis situation should be a part of the education of all veterinarians. In this paper I review those features of postdisaster radionuclide contamination of the food chain most relevant to veterinary activities in ensuring a safe food supply.

Understanding the dietary intakes of infants and toddlers is important because early life nutrition influences future health outcomes. The aim of this study was to determine the dietary sources of total energy and 16 nutrients in a nationally representative sample of U.S. infants and toddlers aged 0-24 months. Data from the 2005-2012 National Health and Nutrition Examination Survey were analyzed. Dietary intake was assessed in 2740 subjects using one 24-h dietary recall. The population proportion was used to determine the contribution of foods and beverages to nutrient intakes. Overall infant formulas and baby foods were the leading sources of total energy and nutrients in infants aged 0-11.9 months. In toddlers, the diversity of food groups contributing to nutrient intakes was much greater. Important sources of total energy included milk, 100% juice and grain based mixed dishes. A number of foods of low nutritional quality also contributed to energy intakes including sweet bakery products, sugar-sweetened beverages and savory snacks. Overall non-flavored milks and ready-to-eat cereals were the most important contributors to micronutrient intakes. In conclusion this information can be used to guide parents regarding appropriate food selection as well as inform targeted dietary strategies within public health initiatives to improve the diets of infants and toddlers.
The future of sugar cane in China and India - Supply constraints and expansion potential

International Nuclear Information System (INIS)

Kostka, Genia; Polzin, Christine; Scharrer, Jenny

2009-01-01

The last decade has seen a surging demand for biofuels in the wake of increasing oil prices and rising environmental concerns. The most common biofuel is bio-ethanol accounting for more than 90% of total biofuel usage. It is increasingly produced from sugar cane making cane a strategic crop for biofuels. Given the growing demand for 'green' fuels, bio-ethanol production has been supported by energy policies in the past decade, which have consequently been accused of contributing to the global trend of rising food prices and thus jeopardising food security. However, while biofuel policies are an important driver, prices as much as food security will ultimately be determined by supply constraints of strategic crops. This paper hence investigates drivers of and constraints to sugar cane production in China and India and shows that supply side constraints vary significantly in the two countries. China and India both face serious limitations with regard to suitable available land for the further expansion of sugar cane production. Equally they are both faced with challenges to increasing yield output per hectare, albeit different ones. With regard to productivity, China achieved 2.7% annual yield growth since 1997, while India has seen yield decreases of -0.1% p.a. over the same period. The authors conclude that cane used as a feedstock to meet the rising energy demand will come at the expense of converting fertile land for non-food purposes.

Climate change influences on the major pillars of food security. Each of the four elements of food security (availability,access,utilization,andstability) is vulnerable to changes in climate. For example,reductions in production related to regional drought influence food availability at multiple scales. Changes in price influences the ability of certain populations to purchase food (access). Utilization maybe affected when production zones shift, reducing the availability of preferred or culturally appropriate types of food within a region. Stability of the food supply may be highly uncertain given an increased incidence of extreme climatic events and their influence on production patterns.

A high sugar intake is a subject of scientific debate due to the suggested health implications and recent free sugar recommendations by the WHO. The objective was to complete a food composition table for added and free sugars, to estimate the intake of total sugars, free sugars, and added sugars, adherence to sugar guidelines and overall diet quality in Dutch children and adults. In all, 3817 men and women (7–69 years) from the Dutch National Food Consumption Survey 2007–2010 were studied. Added and free sugar content of products was assigned by food composition tables and using labelling and product information. Diet was assessed with two 24-h recalls. Diet quality was studied in adults with the Dutch Healthy Diet-index. Total sugar intake was 22% Total Energy (%TE), free sugars intake 14 %TE, and added sugar intake 12 %TE. Sugar consumption was higher in children than adults. Main food sources of sugars were sweets and candy, non-alcoholic beverages, dairy, and cake and cookies. Prevalence free sugar intake diet quality was similar comparing adults adherent and non-adherent to the sugar guidelines, although adherent adults had a higher intake of dietary fiber and vegetables. Adherence to the WHO free sugar guidelines of sugar guidelines was not strongly associated with higher diet quality in adults. PMID:26828518

The relationships between the perceptions and practical implementation of food safety regulations by food suppliers in Taiwan were evaluated. A questionnaire survey was used to identify individuals who were full-time employees of the food supply industry with at least 3 months of experience. Dimensions of perceptions of food safety regulations were classified using the constructs of attitude of employees and corporate concern attitude for food safety regulation. The behavior dimension was classified into employee behavior and corporate practice. Food suppliers with training in food safety were significantly better than those without training with respect to the constructs of perception dimension of employee attitude, and the constructs of employee behavior and corporate practice associated with the behavior dimension. Older employees were superior in perception and practice. Employee attitude, employee behavior, and corporate practice were significantly correlated with each other. Satisfaction with governmental management was not significantly related to corporate practice. The corporate implementation of food safety regulations by suppliers was affected by employees' attitudes and behaviors. Furthermore, employees' attitudes and behaviors explain 35.3% of corporate practice. Employee behavior mediates employees' attitudes and corporate practices. The results of this study may serve as a reference for governmental supervision and provide training guidelines for workers in the food supply industry. Copyright © 2015. Published by Elsevier B.V.

The implementation of a standardized front-of-pack-labelling (FoPL) scheme would likely be a useful tool for many consumers trying to improve the healthfulness of their diets. Our objective was to examine what the traffic light labelling scheme would look like if implemented in the US. Data were extracted from Label Insight’s Open Access branded food database in 2017. Nutrient levels and the proportion of products classified as “Red” (High), “Amber” (Medium) or “Green” (Low) in total fat, saturated fat, total sugar and sodium for food and beverage items were examined. The proportion of products in each category that had each possible combination of traffic light colors, and met the aggregate score for “healthy” was examined. Out of 175,198 products, >50% of all US packaged foods received a “Red” rating for total sugar and sodium. “Confectionery” had the highest mean total sugar (51.9 g/100 g) and “Meat and meat alternatives” the highest mean sodium (781 mg/100 g). The most common traffic light label combination was “Red” for total fat, saturated fat and sodium and “Green” for sugar. Only 30.1% of products were considered “healthy”. A wide variety (n = 80) of traffic light color combinations were observed. A color coded traffic light scheme appears to be an option for implementation across the US packaged food supply to support consumers in making healthier food choices. PMID:28489037

Food irradiation: contributions to public health in developing countries

International Nuclear Information System (INIS)

Sundaram, K.

1976-01-01

It may be seen that with advent of the green revolution, the per capita availability of food has shown an increase during the past decade, although population increase during the period has been significant. Currently, the gap between estimated requirement and availability is small and gives the hope that the country can be self-sufficient in the near future. The national averages often do not tell the full story as economic factors lead to uneven distribution of total food supplies. The shortages are more severely felt by the poorer segments as they are economically unable to demand their full share; thus, economically weaker sections of most developing nations live in a chronic state of near famine. Food irradiation is one of these existing technologies. It is a physical method that can be used to preserve food from microbial and insect damage and infection, as well as from physiological deterioration. In other words, this method can extend the storage life of food considerably without noticeable change of the properties of the food commodity. The impact of food irradiation can be very great especially because of its contribution to the hygienization of food

Food and population.

Science.gov (United States)

1985-04-06

Agricultural producttivity is currently characterized by the paradox of an abundace of food in the developed world and hunger in much of the developing world. In China, India, and many other countries of Asia, the general food supply has kept pace with population growth and should continue to if family planning programs gain momentum. In Africa, on the other hand, the food supply has been falling behind the growth of the population in the majority of countries for the past decade. The situation is especially serious in the Sahel, where the production wf crops for export has been prioritized over local needs. The Food and Agriculture Organization's global information and early warning system is a promising development and can provide alerts when weather or other conditions threaten a harvest. Donor countries can then send in cereals and other foods before there is an actual famine. About 20 disasters in the Sahel are etimated to have been averted by this system, in operation since 1975. In developed countries, the farming industry needs to be restructured in relation to changes in markets and technologies. Solution of the food-population problem depends upon agricultural policies that balance the economic interests of farmers and consumers and also takes into account the need to preserve the countryside.

Burdo O.G.

2017-04-01

Full Text Available The aim of the research is to create innovative evaporating equipment that can produce concentrates with a high content of solids, with a low level of thermal effects on raw materials. The significance of the solution of technological problems of the key process of food technologies - concentration of liquid solutions (juices, extracts, etc. is shown. Problems and scientific contradictions are formulated and the hypothesis on using of electromagnetic energy sources for direct energy transfer to solution’s moisture has been offered. The prospects of such an energy effect are proved by the energy management methods. The schemes of fuel energy conversion for the conventional thermal concentration technology and the innovative plant based on the electromagnetic energy generators are presented. By means of the similarity theory the obtained model is transformed to the criterial one depicted kinetic of evaporation process at the electromagnetic field action. The dimensionless capacity of the plant is expressed by the dependence between the Energetic effect number and relative moisture content. The scheme of automated experimental system for study of the evaporation process in the microwave field is shown. The experimental results of juice evaporation are presented. It has been demonstrated that the technologies of selective energy supply represent an effective tool for improvement of juice concentration evaporative plants. The main result of the research is design of the evaporator that allows reaching juice concentrates with °brix 95 at the temperature as low as 35 °С, i.e. 2…3 times superior than traditional technologies.
Combining Satellite Data and Models to Assess Vulnerability to Climate Change and Its Impact on Food Security in Morocco

Full Text Available This work analyzes satellite and socioeconomic data to explore the relationship between food and wood demand and supply, expressed in terms of net primary production (NPP, in Morocco. A vulnerability index is defined as the ratio of demand to supply as influenced by population, affluence, technology and climate indicators. The present situation (1995–2007, as well as projections of demand and supply, following the Intergovernmental Panel on Climate Change, Scenarios A2 and B2, are analyzed for a 2025 horizon. We find that the food NPP demand increased by 34.5%, whereas the wood consumption NPP demand decreased by 19.3% between 1995 and 2007. The annual NPP required to support the population’s food and wood appropriation was 29.73 million tons of carbon (MTC in 2007, while the landscape NPP production for the same year was 60.24 MTC; indicating that the population appropriates about 50% of the total NPP resources. Both scenarios show increases in demand and decreases in supply. Under A2, it would take more than 1.25 years for terrestrial ecosystems in Morocco to produce the NPP appropriated by populations in one year. This number is 0.70 years under B2. This already high vulnerability for food and wood products is likely to be exacerbated with climate changes and population increase.

2016-01-01

Full Text Available In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.

Increasing access to fresh produce in small retail venues could improve the diet of people in underserved communities. However, small retailers face barriers to stocking fresh produce. In 2014, an innovative distribution program, Community Markets Purchasing Real and Affordable Foods (COMPRA), was launched in Los Angeles with the aim of making it more convenient and profitable for small retailers to stock fresh produce. Our case study describes the key processes and lessons learned in the first 2 years of implementing COMPRA. Considerable investments in staff capacity and infrastructure were needed to launch COMPRA. Early successes included significant week-to-week increases in the volume of produce distributed. Leveraging partnerships, maintaining a flexible operational and funding structure, and broadly addressing store owners' needs contributed to initial gains. We describe key challenges and next steps to scaling the program. Lessons learned from implementing COMPRA could inform other jurisdictions considering supply-side approaches to increase access to healthy food.

This paper reports on the evaluation of the Smart Choices healthy food and drink supply strategy for Queensland schools (Smart Choices) implementation across the whole school environment in state government primary and secondary schools in Queensland, Australia. Three concurrent surveys using different methods for each group of stakeholders that targeted all 1275 school Principals, all 1258 Parent and Citizens' Associations (P&Cs) and a random sample of 526 tuckshop convenors throughout Queensland. Nine hundred and seventy-three Principals, 598 P&Cs and 513 tuckshop convenors participated with response rates of 78%, 48% and 98%, respectively. Nearly all Principals (97%), P&Cs (99%) and tuckshop convenors (97%) reported that their school tuckshop had implemented Smart Choices. The majority of Principals and P&Cs reported implementation, respectively, in: school breakfast programs (98 and 92%); vending machine stock (94 and 83%); vending machine advertising (85 and 84%); school events (87 and 88%); school sporting events (81 and 80%); sponsorship and advertising (93 and 84%); fundraising events (80 and 84%); and sporting clubs (73 and 75%). Implementation in curriculum activities, classroom rewards and class parties was reported, respectively, by 97%, 86% and 75% of Principals. Respondents also reported very high levels of understanding of Smart Choices and engagement of the school community. The results demonstrated that food supply interventions to promote nutrition across all domains of the school environment can be implemented successfully.

In this work a land use model is developed, which derives possible developments of the agriculture regarding the supply from food and energy biomass. The comparative static model LaNuOpt is based on an optimization of the total land rent using linear optimization. The results are determined in scenarios with different market situations and political basic conditions. With a continuance of the current basic conditions the model computes a doubling of the biogas capacities. Classic procedures of the food production are displaced, depending upon accepted market price.As side effect greenhouse gas emissions are saved. With the help of the model further questions can be examined. (orig.)
Opinions on Fresh Produce Food Safety and Quality Standards by Fresh Produce Supply Chain Experts from the Global South and North.

This study describes the results of an on-line survey of fresh produce supply chain experts who work with producers from the Global North (n = 41, 20 countries) and the Global South (n = 63, 29 countries). They expressed their opinion using 1 to 5 Likert scales on several items related to four types of food safety and quality standards and legislation: Codex Alimentarius standards, European Union legislation, national legislation, and private standards. The results reflect the different circumstances under which the Southern and Northern producers operate in relation to the local organization, regulation, and support of the sector; but they also indicate similar challenges, in particular, the challenge of private standards, which were perceived to demand a higher implementation effort than the other three types of standards. Private standards were also strongly perceived to exclude Southern and Northern small- and medium-scale producers from high-value markets, whereas European Union legislation was perceived to strongly exclude, in particular, small- and medium-scale Southern producers. The results further highlight concerns about costly control measures and third-party certification that are required by downstream buyers but that are mostly paid for by upstream suppliers. Food standards are seen in their dual role as a catalyst for implementation of structured food safety management systems on the one hand and as a nontariff barrier to trade on the other hand. The results of the survey also pointed up the advantages of enforcing food safety and food quality standards in terms of knowledge spillover to noncertified activities, increased revenues, and improved food safety of delivered produce. Survey results highlight the importance of technical assistance and support of producers by governments and producer cooperatives or trade associations in the implementation and certification of food standards, along with increased awareness of and training of individuals in
Comparing Food Provided and Wasted before and after Implementing Measures against Food Waste in Three Healthcare Food Service Facilities

2017-08-01

Full Text Available The aim of the study was to reduce food waste in a hospital, a hospital cafeteria, and a residential home by applying a participatory approach in which the employees were integrated into the process of developing and implementing measures. Initially, a process analysis was undertaken to identify the processes and structures existing in each institution. This included a 2-week measurement of the quantities of food produced and wasted. After implementing the measures, a second measurement was conducted and the results of the two measurements were compared. The average waste rate in the residential home was significantly reduced from 21.4% to 13.4% and from 19.8% to 12.8% in the cafeteria. In the hospital, the average waste rate remained constant (25.6% and 26.3% during the reference and control measurements. However, quantities of average daily food provided and wasted per person in the hospital declined. Minimizing overproduction, i.e., aligning the quantity of meals produced to that required, is essential to reducing serving losses. Compliance of meal quality and quantity with customer expectations, needs, and preferences, i.e., the individualization of food supply, reduces plate waste. Moreover, establishing an efficient communication structure involving all actors along the food supply chain contributes to decreasing food waste.
The determination of nutritional requirements for Safe Haven Food Supply System (emergency/survival foods)

Science.gov (United States)

Ahmed, Selina

1987-01-01

The Space Station Safe Haven Food System must sustain 8 crew members under emergency conditions for 45 days. Emergency Survival Foods are defined as a nutritionally balanced collection of high density food and beverages selected to provide for the survival of Space Station flight crews in contingency situations. Since storage volume is limited, the foods should be highly concentrated. A careful study of different research findings regarding starvation and calorie restricted diets indicates that a minimum nutritional need close to RDA is an important factor for sustaining an individual's life in a stressful environment. Fat, protein, and carbohydrates are 3 energy producing nutrients which play a vital role in the growth and maintenance process of human life. A lower intake of protein can minimize the water intake, but it causes a negative nitrogen balance and a lower performance level. Other macro and micro nutrients are also required for nutritional interrelationships to metabolize the other 3 nutrients to their optimum level. The various options for longer duration than 45 days are under investigation.

A total of 16 rice samples, collected from the field, were analyzed by INAA using reactor neutrons from Dhruva reactor. Whereas a total 17 spices collected from market, were analyzed by both INAA and PIGE methods in conjunction with high resolution gamma-ray spectrometry. Aluminium concentration values were found to be in the range of 19-845 mg kg -1 for spices and 15-104 mg kg -1 for rice samples. The methods were validated by analyzing standard reference materials (SRMs) form NIST. (author)

Water and food security is facing increased challenges with population increase, climate and land use change, as well as resource depletion coupled with pollution and unsustainable practices. Coordinated and effective management of limited natural resources have become an imperative to meet these challenges by optimizing the usage of resources under various constraints. In this study, an optimization model is developed for optimal resource allocation towards sustainable water and food security under nutritional, socio-economic, agricultural, environmental, and natural resources constraints. The core objective of this model is to maximize the composite water-food security status by recommending an optimal water and agricultural strategy. The model balances between the healthy nutritional demand side and the constrained supply side while considering the supply chain in between. It equally ensures that the population achieves recommended nutritional guidelines and population food-preferences by quantifying an optimum agricultural and water policy through transforming optimum food demands into optimum cropping policy given the water and land footprints of each crop or agricultural product. Through this process, water and food security are optimized considering factors that include crop-food transformation (food processing), water footprints, crop yields, climate, blue and green water resources, irrigation efficiency, arable land resources, soil texture, and economic policies. The model performance regarding agricultural practices and sustainable food and water security was successfully tested and verified both at a hypothetical and pilot scale levels.

To climatologists food security is dominated by the impacts of weather and climate on food systems. But the link between the atmosphere and food security is more complex. Extreme weather events such as tropical cyclones impact directly on agriculture, but they also impact on the logistical distribution of food and can thus disrupt the food supply chain, especially in urban areas. Drought affects human life and health as well as impacting dramatically on the sustainable development of society. It represents a pending danger for vulnerable agricultural systems that depend on the rainfall, water supply and reservoirs. Developed countries are affected, but the impact is disproportionate within the developing world. Drought, especially when it results in famine, can change the life and economic development of developing nations and stifle their development for decades. A holistic approach is required to understand the phenomena, to forecast catastrophic events such as drought and famine and to predict their societal consequences. In the Food Security recommendations of the Rio+20 Forum on Science, Technology and Innovation for Sustainable Development it states that it is important "To understand fully how to measure, assess and reduce the impacts of production on the natural environment including climate change, recognizing that different measures of impact (e.g. water, land, biodiversity, carbon and other greenhouse gases, etc) may trade-off against each other..." This talk will review the historical link between weather, climate, drought and food supplies; examine the international situation; and summarise the response of the scientific community

Full Text Available The assurance of food security at the individual level doesn’t implicitly provide for the one at family level as the concepts of hunger, malnutrition and food insecurity are the steps of the same process of access restricted to a sufficient supply of food. In order to achieve food security at the individual level the following is necessary: ensuring food availability (production, reserve stocks; redistribution of food availability within the country or out through international exchanges; effective access of the population to purchase food consumer goods, by ensuring its effective demand as required. Food security of families (FFS is required for assuring individual food security (IFS, but it is not sufficient because the food available may be unevenly distributed between family members. National food security (NFS corresponds to the possibilities that different countries have to ensure both FFS and IFS without sacrificing other important objectives. Under the name of GAS is defined the global food security which represents permanent access for the entire population of the globe to the necessary food for a healthy and active life.

Our understanding of food waste in the food supply chain has increased, but very few studies have been published on food waste in primary production. The overall aims of this study were to quantify the total amount of food waste in primary production in Finland, Sweden, Norway and Denmark, and to create a framework for how to define and quantify food waste in primary production. The quantification of food waste was based on case studies conducted in the present study and estimates published in scientific literature. The chosen scope of the study was to quantify the amount of edible food (excluding inedible parts like peels and bones) produced for human consumption that did not end up as food. As a result, the quantification was different from the existing guidelines. One of the main differences is that food that ends up as animal feed is included in the present study, whereas this is not the case for the recently launched food waste definition of the FUSIONS project. To distinguish the 'food waste' definition of the present study from the existing definitions and to avoid confusion with established usage of the term, a new term 'side flow' (SF) was introduced as a synonym for food waste in primary production. A rough estimate of the total amount of food waste in primary production in Finland, Sweden, Norway and Denmark was made using SF and 'FUSIONS Food Waste' (FFW) definitions. The SFs in primary production in the four Nordic countries were an estimated 800,000 tonnes per year with an additional 100,000 tonnes per year from the rearing phase of animals. The 900,000 tonnes per year of SF corresponds to 3.7% of the total production of 24,000,000 tonnes per year of edible primary products. When using the FFW definition proposed by the FUSIONS project, the FFW amount was estimated at 330,000 tonnes per year, or 1% of the total production. Copyright © 2017 Elsevier Ltd.

Post-harvest losses due to sprouting, insect infestation and spoilage by microorganisms is a serious problem in many countries and commonly aggravates the problem of food shortages. In addition, many developing countries also depend largely on agricultural produce, such as grain, tuber and tropical fruit, as major export crops to earn foreign exchange. The use of ionizing radiation as an effective means of disinfecting and/or prolonging the self-life of several food products has been well documented in a number of developing countries. The World health organization (WHO) encourages its Member States to consider all measures to eliminate or reduce food borne pathogens in food and improve their supplies of safe and nutritious food. In regard to its contribution to food safety, food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection or limitation of this process may endanger public health and deprive consumers of the choice of foods processed for safety.
