Just a few days before my career as a fledgling science teacher began in a large public high school in New York City, a mentor suggested I might get some ideas about how to run a classroom from a book called The First Days Of School by Harry Wong. Although the book seemed to concentrate more on elementary students, I found that many of the principles in the book worked well for high school students. Even as I have begun to teach at the university level, many of Wong’s themes have persisted in my teaching style. Wong’s central thesis is that for learning to occur, a teacher must create the proper environment. In education jargon, a good climate for learning is generated via classroom management, an array of methods used by elementary and secondary school teachers to provide structure and routine to a class period via a seamless flow of complementary activities. Many college professors would likely consider classroom management to be chiefly a set of rules to maintain discipline and order among an otherwise unruly herd of schoolchildren, and therefore not a useful concept for mature university students. However, classroom management is much deeper than mere rules for behavior; it is an approach to instructional design that considers the classroom experience holistically. A typical professorial management style is to lecture for an hour or so and ask students to demonstrate learning via examinations several times in a semester. In contrast, a good high school teacher will manage a class from bell-to-bell to create a natural order and flow to a given lesson. In this presentation, I will argue for an approach to college lesson design similar to the classroom management style commonly employed by high school and elementary school teachers. I will suggest some simple, practical techniques learned during my high school experience that work just as well in college: warm-up and practice problems, time management, group activities, bulletin boards, learning environment

In a typical science course learning is teacher directed. Students are presented with knowledge and concepts via textbooks and lecture and then given the opportunity to apply them. Project-based learning (PBL) creates a context and reason to learn information and concepts. In PBL, learning is student directed and teacher facilitated. Students take ownership of their learning by finding, evaluating and synthesizing information from a variety of resources and via interaction between each other. In PBL, the project is central rather than peripheral to the curriculum. It is not just an activity that provides examples, additional practice or applications of the course content, but rather, the vehicle through which major concepts are discovered. The PBL process requires students to do revision and reflection encouraging them to think about what and how they are learning. PBL projects also allow students to develop important life-work skills such as collaboration, communication and critical thinking within the discipline. We have employed PBL in both Liberal Arts courses for non-science majors and upper division courses for science students. Three examples will be discussed. The first will be the production of video documentaries in a non-science major course; the second, a student generated electronic textbook in a 300-level energy course for science students; and lastly, a student designed analysis project in a chemistry major capstone laboratory course. The product in each of these examples was used to deliver knowledge to others in the class as well as members of the public providing motivation for students to do high-quality work. In our examples, student documentaries are publicly screened as part of a university-wide Academic Excellence Showcase; the student generated electronic textbook is available for public use on the internet; and the results of the student designed analysis were communicated to the real-world clients via letters and reports. We will discuss

This research project investigates communication between international teaching assistants and their undergraduate students in university-level chemistry labs. During the fall semester, introductory-level chemistry lab sections of three experienced non-native speaking teaching assistants and their undergraduate students were observed. Digital audio and video recordings documented fifteen hours of lab communication, focusing on the activities and interactions in the first hour of the chemistry laboratory sessions. In follow-up one-on-one semi-structured interviews, the participants (undergraduates, teaching assistants, and faculty member) reviewed interactions and responded to a 10-item, 7-point Likert-scaled interview. Interactions were classified into success categories based on participants' opinions. Quantitative and qualitative data from the observations and interviews guided the analysis of the laboratory interactions, which examined patterns of conversational listening. Analysis of laboratory communication reveals that undergraduates initiated nearly two-thirds of laboratory communication, with three-fourths of interactions less than 30 seconds in duration. Issues of gender and topics of interaction activity were also explored. Interview data identified that successful undergraduate-teaching assistant communication in interactive science labs depends on teaching assistant listening comprehension skills to interpret and respond successfully to undergraduate questions. Successful communication in the chemistry lab depended on the coordination of visual and verbal sources of information. Teaching assistant responses that included explanations and elaborations were also seen as positive features in the communicative exchanges. Interaction analysis focusing on the listening comprehension demands placed on international teaching assistants revealed that undergraduate-initiated questions often employ deixis (exophoric reference), requiring teaching assistants to

If you are interested in food science, looking for a meaningful career path, and are motivated by the desire to make a difference, you may find that a career working for the public good can be very rewarding. Often, such opportunities address issues of social responsibility, sustainability, public health, and/or economic development. Food scientists who choose this path typically have an interest in social and public health issues, and are usually driven by the achievement of some sort of social, health, or societal gain. As food science in itself is a very broad discipline, applying this knowledge for the public good can also take a variety of paths. Whether you're interested in manufacturing, food safety, nutrition, food policy, product development, quality control, marketing and sales, or any other discipline that makes up the diverse field of food science, various opportunities exist to make a difference to society.

We argue that thanks to molecular modeling approaches, many thermodynamic properties required in Food Science and Food Engineering will be calculable within a few hours from first principles in a near future. These new possibilities will enable to bridge via multiscale modeling composition, process and storage effects to reach global optimization, innovative concepts for food or its packaging. An outlook of techniques and a series of examples are given in this perspective. We emphasize solute chemical potentials in polymers, liquids and their mixtures as they cannot be understood and estimated without theory. The presented atomistic and coarse-grained methods offer a natural framework to their conceptualization in polynary systems, entangled or crosslinked homo- or heteropolymers.

Umami is a basic tastes, along with sweet, salty, bitter and sour, which is imparted by glutamate, one of the free amino acids in foods. Since its discovery of umami by a Japanese scientist in 1908, umami is now perceived globally a basic taste. Recent collaboration among chefs and researchers on traditional soup stocks showed a difference in taste profiles of Japanese soup stock 'dashi' and Western style soup stock. The free amino acids profile's in dashi and soup stock showed how Japanese have traditionally adopted a simple umami taste. The exchange of knowledge on cooking methods and diverse types of umami rich foods in different countries displays the blending of the culinary arts, food science and technology for healthy and tasty solutions. Since Japanese cuisine 'WASHOKU' was listed in the 'Intangible Heritage of UNESCO' in 2013, many people in the world now have great interest in Japanese cuisine. One of the unique characteristics of this cuisine is that 'dashi' is an indispensable material for cooking a variety of Japanese dishes. Many chefs from Europe, US and South America have come to Japan to learn Japanese cuisine in the last 10 years, and umami has become recognized as a common taste worldwide. Researchers and culinary professionals have begun to pay attention to the traditional seasonings and condiments rich in glutamate available throughout the world.

Microrheology provides a technique to probe the local viscoelastic properties and dynamics of soft materials at the microscopic level by observing the motion of tracer particles embedded within them. It is divided into passive and active microrheology according to the force exerted on the embedded particles. Particles are driven by thermal fluctuations in passive microrheology, and the linear viscoelasticity of samples can be obtained on the basis of the generalized Stokes-Einstein equation. In active microrheology, tracer particles are controlled by external forces, and measurements can be extended to the nonlinear regime. Microrheology techniques have many advantages such as the need for only small sample amounts and a wider measurable frequency range. In particular, microrheology is able to examine the spatial heterogeneity of samples at the microlevel, which is not possible using traditional rheology. Therefore, microrheology has considerable potential for studying the local mechanical properties and dynamics of soft matter, particularly complex fluids, including solutions, dispersions, and other colloidal systems. Food products such as emulsions, foams, or gels are complex fluids with multiple ingredients and phases. Their macroscopic properties, such as stability and texture, are closely related to the structure and mechanical properties at the microlevel. In this article, the basic principles and methods of microrheology are reviewed, and the latest developments and achievements of microrheology in the field of food science are presented.

As participants at the Ecosystem Inception Meeting convened by the Global Dairy Platform and held in Chicago in June 2016, we have identified some concepts as central to the study of food systems science. Following the definition developed by the Food and Agriculture Organization for sustainable diets, the food supply needs to provide foods that are healthy and safe, affordable, culturally acceptable, and with low impact on the environment. Therefore, the four main domains of sustainable food systems science can be described as health, economics, society, and the environment. Food systems science needs to embrace and engage with all relevant allied disciplines that may include environmental health sciences, epidemiology, geography, history, sociology, anthropology, business, and political science. Research and training in food systems science, both domestic and international, would benefit from a set of competencies, from more extensive research networks, and from more public-private engagement. This document builds on major advances in the area of food system research, training, and practice, already achieved by individuals, institutions, foundations, and local and national governments.

A national food irradiation forum was held to further promote the use of irradiation for food applications. This offered opportunity for the Department of National Health to announce new legislation for the labelling of irradiated foodstuffs. Subjects which dominated the proceedings included the implementation of labelling legislation and consumer education; cost implications and commercialisation of radurisation; the increasing trend towards the radurisation of processed foodstuffs as opposed to fresh and the future of food irradiation in South Africa. The safety of the irradiation process was stressed. The forum came to the conclusion that South Africa has this technology which has the government's stamp of approval and it is now up to the food industry, the Consumer Council, etc., to educate consumers into realising that they are buying quality products - and that the Radura symbol is a symbol of quality

The rapid growth in global enrolment of students for higher education observed in recent decades is expected to continue in the early next century. However, the role of the universities and their approach to education may undergo substantial transformation in the future. The Internet is expected to play a significant role in university-level education in general and renewable energy education (REE) in particular. Currently, REE at different universities is characterized by a lack of uniformity in terms of duration, coursework, emphasis on research, etc. There is a need to establish guidelines and standards regarding academic programs and to establish a system of accreditation, preferably global, of REE in different academic disciplines and departments.

Full Text Available Differences in regulations result in needless destruction of safe food and hamper food trade. The differences are not just the result of the history of food safety regulations, often developed in times before global cooperation, but are also built in new regulations. It may be responses to media hypes or for other reasons, but in most cases the differences cannot be justified scientifically. A major difficulty is that, due to the developments in analytical techniques the number of chemicals that are found in food is increasing rapidly and chemicals are always suspected to be a safety risk. By far most chemicals are of natural origin but could not be detected in the past because the methods available in the past were not sensitive enough. Demanding the absence of chemicals because the risk they present is unknown, however, would eventually make all food unacceptable. The general public should be shown that everything they eat is chemical, and all food components will be toxic if the amount is too high. It should also be shown that many of these chemicals will also cause illness and death if there is not enough of it as is the case with vitamins and minerals.

This paper provides an overview of the evolution of food labeling in the USA. It briefly describes the three phases of agricultural development consisting of naturally occurring, cross-bred, and genetically engineered, edited or modified crops, otherwise known as Genetically Modified Organisms (GMO). It uses the Best Available Regulatory Science (BARS) and Metrics for Evaluation of Regulatory Science Claims (MERSC) to evaluate the scientific validity of claims applicable to GMO and the Best Available Public Information (BAPI) to evaluate the pronouncements by public media and others. Subsequently claims on health risk, ecological risk, consumer choice, and corporate greed are evaluated based on BARS/MERSC and BAPI. The paper concludes by suggesting that labeling of food containing GMO should consider the consumer's choice, such as the food used by those who desire kosher and halal food. Furthermore, the consumer choice is already met by the exclusion of GMO in organic food.

Full Text Available Recently, machine vision is gaining attention in food science as well as in food industry concerning food quality assessment and monitoring. Into the framework of implementation of Process Analytical Technology (PAT in the food industry, image processing can be used not only in estimation and even prediction of food quality but also in detection of adulteration. Towards these applications on food science, we present here a novel methodology for automated image analysis of several kinds of food products e.g. meat, vanilla crème and table olives, so as to increase objectivity, data reproducibility, low cost information extraction and faster quality assessment, without human intervention. Image processing's outcome will be propagated to the downstream analysis. The developed multispectral image processing method is based on unsupervised machine learning approach (Gaussian Mixture Models and a novel unsupervised scheme of spectral band selection for segmentation process optimization. Through the evaluation we prove its efficiency and robustness against the currently available semi-manual software, showing that the developed method is a high throughput approach appropriate for massive data extraction from food samples.

Students who leave STEM degree programs often cite uninspiring instruction in introductory courses, including traditional lecturing, as a reason. While undergraduate courses play a critical role in STEM retention, little is understood about the instructional transitions students encounter upon moving from secondary to post-secondary STEM courses. This study compares classroom observation data collected using the Classroom Observation Protocol for Undergraduate STEM from over 450 middle school, high school, introductory-level university, and advanced-level university classes across STEM disciplines. We find similarities between middle school and high school classroom instruction, which are characterized by a large proportion of time spent on active-learning instructional strategies, such as small-group activities and peer discussion. By contrast, introductory and advanced university instructors devote more time to instructor-centered teaching strategies, such as lecturing. These instructor-centered teaching strategies are present in classes regardless of class enrollment size, class period length, or whether or not the class includes a separate laboratory section. Middle school, high school, and university instructors were also surveyed about their views of what STEM instructional practices are most common at each educational level and asked to provide an explanation of those perceptions. Instructors from all levels struggled to predict the level of lecturing practices and often expressed uncertainty about what instruction looks like at levels other than their own. These findings suggest that more opportunities need to be created for instructors across multiple levels of the education system to share their active-learning teaching practices and

Hunger has been a concern for generations and has continued to plague hundreds of millions of people around the world. Although many efforts have been devoted to reduce hunger, challenges such as growing competitions for natural resources, emerging climate changes and natural disasters, poverty, illiteracy, and diseases are posing threats to food security and intensifying the hunger crisis. Concerted efforts of scientists to improve agricultural and food productivity, technology, nutrition, and education are imperative to facilitate appropriate strategies for defeating hunger and malnutrition. This paper provides some aspects of world hunger issues and summarizes the efforts and measures aimed to alleviate food problems from the food and nutritional sciences perspectives. The prospects and constraints of some implemented strategies for alleviating hunger and achieving sustainable food security are also discussed. This comprehensive information source could provide insights into the development of a complementary framework for dealing with the global hunger issue.

Genetically modified (GM) food is discussed as an example of the controversial relation between the intrinsic uncertainty of the scientific approach and the demand of citizen-consumers to use products of science innovation that are known to be safe. On the whole, peer-reviewed studies on GM food safety do not note significant health risks, with a few exceptions, like the most renowned "Pusztai affair" and the recent "Seralini case." These latter studies have been disregarded by the scientific community, based on incorrect experimental designs and statistic analysis. Such contradictory results show the complexity of risk evaluation, and raise concerns in the citizen-consumers against the GM food. A thoughtful consideration by scientific community and decision makers of the moral values that are present in risk evaluation and risk management should be the most trustable answer to citizen-consumers to their claim for clear and definitive answers concerning safety/un-safety of GM food.

Antioxidant foods and ingredients are an important component of the food industry. In the past, antioxidants were used primarily to control oxidation and retard spoilage, but today many are used because of putative health benefits. However, the traditional message that oxidative stress, which involves the production of reactive oxygen species (ROS), is the basis for chronic diseases and aging is being reexamined. Accumulating evidence suggests that ROS exert essential metabolic functions and that removal of too many ROS can upset cell signaling pathways and actually increase the risk of chronic disease. It is imperative that the food industry be aware of progress in this field to present the science relative to foods in a forthright and clear manner. This may mean reexamining the health implications of adding large amounts of antioxidants to foods.
Full Text Available The regulation of a profession is justified when it improves consumer protection and public health. Higher education food science and technology (FST degrees, widely offered in many universities in Europe open to a wide range of jobs in the food sectors where the employees could cover different positions, roles and carry out diverse activities dealing with the food production and the quality and safety of the food products. This work reviews the state of the art of the FST regulated professions requiring higher education qualifications in the European countries. The research was carried out by collecting specific information on regulated professions by contacting unions, professional associations, public servant categories/professions, and by visiting national and EU websites. The data collected for each regulated profession were: country, training/education required, date of implementation of regulation, professional training (if required, capability test (if required and acts required by law to be signed by a regulated professional. Only professions that required a higher education diploma were included in this search. Few countries were found to have a regulated profession in FST, in particular: Food Engineering (Turkey, Food Technologist (Greece, Iceland, Italy and Slovenia, and Oenologist (Italy, Portugal and Spain. FST regulated professions in Europe are thus scarce and have a rather limited history. The Food Technologist in Italy and the Food Engineer in Turkey were found to be the only completely regulated professions found in Europe. Food and professional regulation have been evolved over the years and raised the debate on the regulation of FST professions. Academia as well as other policymakers has to further contribute to this discussion to keep high the standards for quality of education and training of the qualified workforce and professionals in the food sector.

The Food and Agriculture Organization (FAO) predicts that food production must rise 70% over the next 40 years to meet the demands of a growing population that is expected to reach nine billion by the year 2050. Many facets of basic plant science promoted by the Botanical Society of America are important for agriculture; however, more explicit connections are needed to bridge the gap between basic and applied plant research. This special issue, Speaking of Food: Connecting Basic and Applied Plant Science, was conceived to showcase productive overlaps of basic and applied research to address the challenges posed by feeding billions of people and to stimulate more research, fresh connections, and new paradigms. Contributions to this special issue thus illustrate some interactive areas of study in plant science-historical and modern plant-human interaction, crop and weed origins and evolution, and the effects of natural and artificial selection on crops and their wild relatives. These papers provide examples of how research integrating the basic and applied aspects of plant science benefits the pursuit of knowledge and the translation of that knowledge into actions toward sustainable production of crops and conservation of diversity in a changing climate. © 2014 Botanical Society of America, Inc.

Indonesia, as a major population in the Asia Pacific region, threatened with food and health insecurity through climate change and rapid economic development, faces the challenge to build capacity among its science-based food and health professionals and institutions. The nutrition research agenda is now being more actively set within the region, rather than by external imposition. A series of papers emanating from a new generation of public health and clinical nutrition scientists is reported in this issue of APJCN. It draws attention to the importance of food patterns and background culture as contributors to the failure of the nutrient rather than a food, food system and socio-ecological approach to solve the region's intransigent nutritionally-related health problems. New understandings of human eco-social biology are providing opportunities to accelerate the resolution of these problems. The challenge is to transform the food-health construct from one which is not sufficiently concerned about the precarious state of ecologically dysfunctional health and its nutrient market drivers to one which strives for more sustainable and affordable solutions. The present reports address a range of options to these ends.

Emerging interdisciplinary science efforts are providing new understanding of the interdependence of food, energy, and water (FEW) systems. These science advances, in turn, provide critical information for coordinated management to improve the affordability, reliability, and environmental sustainability of FEW systems. Here we describe the current state of the FEW nexus and approaches to managing resource conflicts through reducing demand and increasing supplies, storage, and transport. Despite significant advances within the past decade, there are still many challenges for the scientific community. Key challenges are the need for interdisciplinary science related to the FEW nexus; ground-based monitoring and modeling at local-to-regional scales; incorporating human and institutional behavior in models; partnerships among universities, industry, and government to develop policy relevant data; and systems modeling to evaluate trade-offs associated with FEW decisions.

Observed changes in eating and drinking behaviors in economically developing countries are associated with increase of obesity and related chronic diseases. Researchers from field of public health (PH) have attributed this problem to food processing and have created new food classification systems to support their thesis. These classifications conceptually differ from processing level concepts in food science, and state to people that food processing is directly related to nutritional impact of food. Our work aims to compare the concept of food processing from the standpoint of food science and technology (FST) and public health and to discuss differences related to formulation or level of processing of products and their impact on nutritional quality. There is a misconception between food processing/unit operation/food technology and formulation or recipes. For the public health approach, classification is based on food products selection and the use of ingredients that results in higher consumption of sugar, sodium, fat, and additives, whereas in FST, processing level is based on the intensity and amount of unit operations to enhance shelf life, food safety, food quality, and availability of edible parts of raw materials. Nutritional quality of a product or preparation is associated with formulation/recipe and not with the level of processing, with few exceptions. The impact of these recommendations on the actual comprehension of food processing and quality must be considered by the population.

Food science and technology education has been running since four decades in Nepal. There is a very slow improvement in the profession. The job opportunities have always been threatened by insiders and outsiders. Academic institutions, government agencies, and food industries themselves are responsible for the quality of food science professionals. Novel and practical methods of teaching should be followed. The government and private organizations should facilitate the recruitment of food technologists. Constant prodding needs to be done for the establishment of a Council with more authority that could monitor all bodies associated with food science professionals. PMID:25493177

Full Text Available Abstract Creative, inquiry-driven approaches in science education help to address the growing need to effectively engage students and promote the public understanding of science. Here we describe an interactive format using food that can be applied both in a course for undergraduate students, as well as in a lecture for the general public. Communicating science through food may also dispel fear of naturally occurring chemicals as well as scientific misconceptions that are propagated by the media.

Full Text Available Today, the attention to food security has grown with the awareness of resources’ scarcity, earth excessive exploitation, population growth and climate change, all factors that are associated with an impelling food emergency. A plethora of theoretical perspectives adopted in analysing food security issue reflects in diverse normative approaches. Some focus on the rapport between population demand and food supply, seeking to reduce the former or increase the latter in order to achieve food security. Applying the technological progress of scientific research will have its positive outcomes: production will increase, keeping prices low; the limited resources will be used more efficiently, decreasing the consumption of water, energy and land; the environment will benefit from a more sustainable production. However, scientific solutions, such as population control, that do not restore individuals’ entitlement to food will be ineffective in preventing food insecurity. Therefore, food security it is not achievable by the sole means of science. A greater quantity of food does not guarantee a more equal distribution of resources. Increasing food production without altering its uneven distribution will only augment this inequality, making who has access to food more secure but not helping who is currently affected by the food insecurity issues. Science can play its role, but development towards the solutions to food insecurity must be led by politics.

The goal of this project was to provide an opportunity for high school students to participate in university-level research projects. In this case, students from Pinkerton Academy (Derry, New Hampshire) were invited to participate in efforts to catalog data from the COMPTEL experiment on NASA's Compton Gamma-Ray Observatory (CGRO). These activities were part of a senior level honors course at Pinkerton. Although the success of this particular program was rather limited, we feel that the general concept is a sound one. In principle, the concept of partnerships between local schools and university researchers is one that could be especially attractive to soft money researchers. Programs can be carefully designed to benefit both the students and the research program.

Irradiation Food has been approved in 52 countries worldwide. In Korea, 26 food items have been approved since 1987. Recently, the irradiation technology with high dose was applied for the development of Korean space foods. Besides the sanitary purpose, the irradiation technology was used for elimination of undesired products such as food allergens, nitrite, biogenic amines, and so on. In this paper, the status of irradiation in the field of food and other biotechnology in Korea will be presented. Food irradiation is known to be the best method for controlling pathogenic microorganisms and one of the best alternatives to the chemical fumigants or preservatives usually used for a sanitation treatment for international trade. Also, there are larger industrial groups dedicated to radiation processing other than food irradiation industry. In this paper, the status of irradiation food science and biotechnology in Korea will be presented

Food allergy is a significant health issue in the UK, affecting between 1 and 2% of adults and 5 and 8% of children. The UK Food Standards Agency seeks to ensure the safety of food allergic consumers by providing them with information and guidance on food choices. Since 1995, with the aim of addressing important policy issues and improving the quality of the support and guidance available for food allergic consumers, the Agency (and before that the Ministry of Agriculture, Fisheries and Food), has had a programme of research dedicated to investigating the causes and mechanisms of food allergy and delivering benefits for UK consumers. In this paper, we outline some of the major scientific challenges that the programme has sought to address. We reflect on how the findings have been used as a basis for the development of sound, evidence-based policy and advice for UK consumers, and the current direction of research being supported by the programme.

The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. In 2007-2008, a foods curriculum developed by professionals in nutrition and education was implemented in 10 3(rd)-grade classrooms in Appalachian Ohio; teachers in these classrooms implemented 45 hands-on foods activities that covered 10 food topics. Subjects included measurement; food safety; vegetables; fruits; milk and cheese; meat, poultry, and fish; eggs; fats; grains; and meal management. Students in four other classrooms served as the control group. Mainstream 3(rd)-grade students were targeted because of their receptiveness to the subject matter, science standards for upper elementary grades, and testing that the students would undergo in 4(th) grade. Teachers and students alike reported that the hands-on FoodMASTER curriculum experience was worthwhile and enjoyable. Our initial classroom observation indicated that the majority of students, girls and boys included, were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations.

Per- and polyfluoroalkyl substances (PFASs) are highly persistent synthetic chemicals, some of which have been associated with cancer, developmental toxicity, immunotoxicity, and other health effects. PFASs in grease-resistant food packaging can leach into food and increase dietary exposure. We collected ∼400 samples of food contact papers, paperboard containers, and beverage containers from fast food restaurants throughout the United States and measured total fluorine using particle-induced γ-ray emission (PIGE) spectroscopy. PIGE can rapidly and inexpensively measure total fluorine in solid-phase samples. We found that 46% of food contact papers and 20% of paperboard samples contained detectable fluorine (>16 nmol/cm2). Liquid chromatography/high-resolution mass spectrometry analysis of a subset of 20 samples found perfluorocarboxylates, perfluorosulfonates, and other known PFASs and/or unidentified polyfluorinated compounds (based on nontargeted analysis). The total peak area for PFASs was higher in 70% of samples (10 of 14) with a total fluorine level of >200 nmol/cm2 compared to six samples with a total fluorine level of food packaging demonstrates their potentially significant contribution to dietary PFAS exposure and envi

Atomic force microscopy (AFM) provides a method for detecting nanoscale structural information. First, this review explains the fundamentals of AFM, including principle, manipulation, and analysis. Applications of AFM are then reported in food science and technology research, including qualitative macromolecule and polymer imaging, complicated or quantitative structure analysis, molecular interaction, molecular manipulation, surface topography, and nanofood characterization. The results suggested that AFM could bring insightful knowledge on food properties, and the AFM analysis could be used to illustrate some mechanisms of property changes during processing and storage. However, the current difficulty in applying AFM to food research is lacking appropriate methodology for different food systems. Better understanding of AFM technology and developing corresponding methodology for complicated food systems would lead to a more in-depth understanding of food properties at macromolecular levels and enlarge their applications. The AFM results could greatly improve the food processing and storage technologies.
The Food Safety Modernization Act improves oversight of America's food safety system. Title III, which regulates imported food, may create extra burdens for importers and therefore act as a barrier to trade. What will be on trial before the World Trade Organization (WTO), however, is not the law's content, but the science supporting it. Under the WTO regime, food safety laws that could restrict the free movement of food commodities must be sufficiently justified by scientific evidence. Member states must engage in risk assessments and regulate food imports in a manner that is "no more restrictive than necessary" to protect against the health risks identified by scientific evidence. This article examines the requirements of the WTO to evaluate the FSMA's legality under WTO rules. It analyzes the case law of the WTO Panel and Appellate Body and compares the FMSA to the EU's General Food Law.

In recent years, the food science sector has gained importance since the society is focusing on high-quality and safety foods. With a specific end goal to meet this societal need, the research and development organizations in India have adopted innovative technical and research processes, which gave more accentuation on intellectual assessment in food processing industry. The global Intellectual Property regime in food science sector had witnessed an increment in the number of patents filed and granted during 2006-2010. Ever since there has been a gradual increase in the number of patents applied mainly in food processing industries by research organizations related to food sciences, for example, those working under the aegis of ICAR and CSIR in India. In this study, a review has been done on the intellectual assets generated by ICAR and other national research organizations in India, in the food science sector. Emphasis has been given on the global relevance of these assets, modes of IP protection and technology transfer mechanisms followed by different public and private organizations.

The benefits of chocolate can be enjoyed without guilt as part of a healthful balanced diet.
Numerous genes are involved in innate and adaptive immunity and these have been modified over millions of years. During this evolution, the mucosal immune system has developed two anti-inflammatory strategies: immune exclusion by the use of secretory antibodies to control epithelial colonization of microorganisms and to inhibit the penetration of potentially harmful agents; and immunosuppression to counteract local and peripheral hypersensitivity against innocuous antigens, such as food proteins. The latter strategy is called oral tolerance when induced via the gut. Homeostatic mechanisms also dampen immune responses to commensal bacteria. The mucosal epithelial barrier and immunoregulatory network are poorly developed in newborns. The perinatal period is, therefore, critical with regard to the induction of food allergy. The development of immune homeostasis depends on windows of opportunity during which innate and adaptive immunity are coordinated by antigen-presenting cells. The function of these cells is not only orchestrated by microbial products but also by dietary constituents, including vitamin A and lipids, such as polyunsaturated omega-3 fatty acids. These factors may in various ways exert beneficial effects on the immunophenotype of the infant. The same is true for breast milk, which provides immune-inducing factors and secretory immunoglobulin A, which reinforces the gut epithelial barrier. It is not easy to dissect the immunoregulatory network and identify variables that lead to food allergy. This Review discusses efforts to this end and outlines the scientific basis for future food allergy prevention.
Full Text Available Food safety concerns people's health, life, even social harmony and stability. Also, it is an important scientific problem of the development of mankind. How could we strengthen our national food security? Firstly, a long-lasting scientific system of food safety should be formed. Only by enhancing the construction of this scientific system, building up the development platform of food safety, improving the science and technology level in this field, carrying out the rapid detection skills of food safety, controlling technology research, forming a joint force of government regulation and public surveillance, we could ensure food security fundamentally. Secondly, we need form a management system with strict legal liability and clear public responsibility, and need establish a food safety warning system and risk assessment system, strengthen the food information construction, improve the international standards of food quality, and constantly increase the level of food safety, so as to control the food pollution, reduce the foodborne diseases, and ensure the consumer’s health.

This article serves as an overview, introducing the currently popular area of supercritical fluids and their uses in food biotechnology. Within each application, and wherever possible, the basic principles of the technique, as well as a description of the history, instrumentation, methodology, uses, problems encountered, and advantages over the traditional, non-supercritical methods are given. Most current commercial application of the supercritical extraction involve biologically-produced materials; the technique may be particularly relevant to the extraction of biological compounds in cases where there is a requirement for low-temperature processing, high mass-transfer rates, and negligible carrying over of the solvent into the final product. Special applications to food processing include the decaffeination of green coffee beans, the production of hops extracts, the recovery of aromas and flavors from herbs and spices, the extraction and fractionation of edible oils, and the removal of contaminants, among others. New advances, in which the extraction is combined with reaction or crystallization steps, may further increase the attractiveness of supercritical fluids in the bioprocess industries. To develop and establish a novel and effective alternative to heating treatment, the lethal action of high hydrostatic pressure CO(2) on microorganisms, with none or only a minimal heating process, has recently received a great deal of attention.

Food and engineering sciences have tended to neglect the importance of human nutrition sciences and clinical study of new molecules discovered by food engineering community, and vice versa. Yet, the value of systems thinking and use of omics technologies in food engineering are rapidly emerging. Foodomics is a new concept and practice to bring about "precision nutrition" and integrative bioengineering studies of food composition, quality, and safety, and applications to improve health of humans, animals, and other living organisms on the planet. Foodomics signals a three-way convergence among (1) food engineering; (2) omics systems science technologies such as proteomics, metabolomics, glycomics; and (3) medical/life sciences. This horizon scanning expert review aims to challenge the current practices in food sciences and bioengineering so as to adopt foodomics and systems thinking in foodstuff analysis, with a focus on possible applications of metabolomics. Among the omics biotechnologies, metabolomics is one of the prominent analytical platforms of interest to both food engineers and medical researchers engaged in nutritional sciences, precision medicine, and systems medicine diagnostics. Medical and omics system scientists, and bioengineering scholars can mutually learn from their respective professional expertise. Moving forward, establishment of "Foodomics Think Tanks" is one conceivable strategy to integrate medical and food sciences innovation at a systems scale. With its rich history in food sciences and tradition of interdisciplinary scholarship, the Silk Road countries offer notable potential for synthesis of diverse knowledge strands necessary to realize the prospects of foodomics from Asia and Middle East to Europe.

The polymer is composed of D-mannuronic acid and L-guluronic acid subunits and is a component of cell walls. It is commonly used as a thickener in foods such as ice cream and fruit-filled snacks. For the demonstration, a 2% solution of sodium alginate is poured into a 1% solution of calcium chloride. Nontoxic calcium alginate "worms" form due to crosslinking of the polymer. Alternatively, the commercially available antacid Gaviscon can be used as a source of sodium alginate. The crosslinks can then be broken by shaking the worms in brine. The demonstration is a fine addition to any chemical educator's repertoire of polymer experiments.
The status of education in nuclear and radiochemistry in Slovenia is reviewed and elucidated at both undergraduate and graduate levels. It is observed that both the quantity and the quality of studies have deteriorated during recent years/decades, thus following similar trends in the developed countries. Presently, no dedicated study of radioactivity is offered within the country. The main reason for this deterioration is a general decline of interest for studying nuclear sciences and the limited need for such specialization in a small country such as Slovenia. (author)

Forecast Mekong is a significant international thrust under the Delta Research and Global Observation Network (DRAGON) of the U.S. Geological Survey (USGS) and was launched in 2009 by the U.S. Department of State and the Foreign Ministers of Cambodia, Laos, Thailand, and Vietnam under U.S. Department of State Secretary Hillary R. Clinton's Lower Mekong Initiative to enhance U.S. engagement with countries of the Lower Mekong River Basin in the areas of environment, health, education, and infrastructure. Since 2009, the USGS has worked closely with the U.S. Department of State; personnel from Cambodia, Laos, Thailand, and Vietnam; nongovernmental organizations; and academia to collect and use research and data from the Lower Mekong River Basin to provide hands-on results that will help decisionmakers in future planning and design for restoration, conservation, and management efforts in the Lower Mekong River Basin. In 2012 Forecast Mekong is highlighting the increasing cooperation between the United States and Lower Mekong River Basin countries in the areas of food and environmental security. Under the DRAGON, Forecast Mekong continues work in interactive data integration, modeling, and visualization system by initiating three-dimensional bathymetry and river flow data along with a pilot study of fish distribution, population, and migratory patterns in the Lower Mekong River Basin. When fully developed by the USGS, in partnership with local governments and universities throughout the Mekong River region, Forecast Mekong will provide valuable planning tools to visualize the consequences of climate change and river management.

Full text: Plasma spectrometry has many applications in food science in analysis of a wide range of samples in the food chain. Food science in the broadest sense can be extended to include soil chemistry, plant uptake and, at the other end of the food chain, studies into the metabolic fate of particular elements or elemental species when the foods are consumed by humans or animals. Inductively Coupled Plasma Mass Spectrometry allows multi-element measurements of most elements in the periodic table. A very sensitive analytical technique for trace analysis of samples can be performed by inductively plasma mass spectrometer with quadrupolar detector using ultrasonic nebulization. High Performance Liquid Chromatography (HPLC) is an analytical technique for the separation and determination of organic and inorganic solutes in any samples especially biological, pharmaceutical, food, environmental. The present paper emphasizes that the future tendencies HPLC-ICP-MS is often the preferred analytical technique for these applications due to the simplicity of the coupling between the HPLC and ICP-MS Varian 820 using ultrasonic nebulization, potential for on-line separations with high species specificity and the capability for optimum limits of detection without the necessity of using complex hydride generation mechanisms.

This paper reviews university-level efforts to improve understanding of anthropogenic global climate change (AGCC) through curricula that enable student scientific inquiry. We examined 152 refereed publications and proceedings from academic conferences and selected 26 cases of inquiry learning that overcome specific challenges to AGCC teaching. This review identifies both the strengths and weaknesses of each of these case studies. It is the first to go beyond examining the impact of specific inquiry instructional approaches to offer a synthesis of cases. We find that inquiry teaching can succeed by concretising scientific processes, providing access to global data and evidence, imparting critical and higher order thinking about AGCC science policy and contextualising learning with places and scientific facts. We recommend educational researchers and scientists collaborate to create and refine curricula that utilise geospatial technologies, climate models and communication technologies to bring students into contact with scientists, climate data and authentic AGCC research processes. Many available science education technologies and curricula also require further research to maximise trade-offs between implementation and training costs and their educational value.

This study aims to describe the association between dietary habits and weight status and the interest in food and science. We examined in a cross-sectional study 525 children aged between 8 and 18 years, who attended the Brussels Food Fair or the Belgian Science Day in 2013. They were divided into three groups: special interest in science, special interest in food, and a general control group. They completed a questionnaire, and body parameters were measured. The weight status of the children was identified using the growth charts and the calculated BMI. In total, 525 children were included: 290 children in the reference group, 194 in the food group, and 41 in the science group. The prevalence of overweight and obesity was 28% in the general control group, 14% in the food group, and 15% in the science group. Breakfast and dinner were skipped more often by children with overweight or obesity. Children from the food and science groups had more sweets and meat, had less fruit, and skipped less meals. In our study, 28% of the reference group had overweight or obesity. The children with special interest in food or science differed from the control group.

Full Text Available Food technology innovation has the potential to deliver many benefits to society, although some technologies have been problematic in terms of public acceptance. In promoting the commercial success of innovative technological processes and resultant products it will be important to incorporate information relating to consumer preferences and concerns during their development. The barriers to the utilisation of consumer information during technological development was explored using a two round Delphi study involving 75 experts with an interest in new food technology (food technologists and consumer scientists. There was overall agreement that consumer information should be used in technology implementation and product design, and that good communication between key actors at pivotal stages during the development of new food technologies and products was important. However disciplinary differences were perceived to be a barrier to communication, as were difficulties associated with producing consumer information usable by food technologists. A strategy to improve inter-disciplinary communication is proposed, involving the creation of multi-disciplinary teams working together throughout the development project’s duration, including those with interdisciplinary experience. Deficiencies in the specification of the information required from consumer scientists need to be overcome. Consumer science results need to be concrete and presented as salient to and usable by food technologists.

Because food and poultry industries are demanding an improvement in written communication skills among graduates, research paper writing should be an integral part of a senior undergraduate class. However, scientific writing assignments are often treated as secondary to developing the technical skills of the students. Scientific research paper writing has been emphasized in an undergraduate course on advanced food microbiology taught in the Poultry Science Department at Texas A& M University (College Station, TX). Students' opinions suggest that research paper writing as part of a senior course in Poultry Science provides students with scientific communication skills and useful training for their career, but more emphasis on reading and understanding scientific literature may be required.
Thus, key computational medicinal chemistry methods like molecular dynamics can be used to decipher protein flexibility and to obtain stable models for docking and scoring in food-related studies, and virtual screening is increasingly being applied to identify molecules with potential to act as endocrine disruptors, food mycotoxins, and new nutraceuticals [3,4,5]. All of these methods and simulations are based on protein-ligand interaction phenomena, and represent the basis for any subsequent modification of the targeted receptor's or enzyme's physiological activity. We describe here the energetics of binding of biological complexes, providing a survey of the most common and successful algorithms used in evaluating these energetics, and we report case studies in which computational techniques have been applied to food science issues. In particular, we explore a handful of studies involving the estrogen receptors for which we have a long-term interest.

There is great uncertainty due to challenges of escalating population growth and climate change. Public perception that diverges from the scientific community may decrease the effectiveness of scientific inquiry and innovation as tools to solve these challenges. The objective of this study was to identify the factors associated with the divergence of public opinion from scientific consensus regarding the safety of genetically modified (GM) foods and human involvement in global warming (GW). Results indicate that the effects of knowledge on public opinion are complex and non-uniform across types of knowledge (i.e., perceived and actual) or issues. Political affiliation affects agreement with science; Democrats were more likely to agree that GM food is safe and human actions cause GW. Respondents who had relatively higher cognitive function or held illusionary correlations about GM food or GW were more likely to have an opinion that differed from the scientific community.

A Citizen Science approach was implemented in the laboratory practices of Genetics at the University of Oviedo, related with the engaging topic of Food Control. Real samples of food products consumed by students at home (students as samplers) were employed as teaching material in three different courses of Genetics during the academic year 2014-2015: Experimental Methods in Food Production (MBTA) (Master level), and Applied Molecular Biology (BMA) and Conservation Genetics and Breeding (COMGE) (Bachelor/Degree level). Molecular genetics based on PCR amplification of DNA markers was employed for species identification of 22 seafood products in COMGE and MBTA, and for detection of genetically modified (GM) maize from nine products in BMA. In total six seafood products incorrectly labeled (27%), and two undeclared GM maize (22%) were found. A post-Laboratory survey was applied for assessing the efficacy of the approach for improving motivation in the Laboratory Practices of Genetics. Results confirmed that students that worked on their own samples from local markets were significantly more motivated and better evaluated their Genetic laboratory practices than control students (χ(2) = 12.11 p = 0.033). Our results suggest that citizen science approaches could not be only useful for improving teaching of Genetics in universities but also to incorporate students and citizens as active agents in food control. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):450-462, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

Predictive microbiology is considered in the context of the conference theme "chance, innovation and challenge", together with the impact of quantitative approaches on food microbiology, generally. The contents of four prominent texts on predictive microbiology are analysed and the major contributions of two meat microbiologists, Drs. T.A. Roberts and C.O. Gill, to the early development of predictive microbiology are highlighted. These provide a segue into R&D trends in predictive microbiology, including the Refrigeration Index, an example of science-based, outcome-focussed food safety regulation. Rapid advances in technologies and systems for application of predictive models are indicated and measures to judge the impact of predictive microbiology are suggested in terms of research outputs and outcomes. The penultimate section considers the future of predictive microbiology and advances that will become possible when data on population responses are combined with data derived from physiological and molecular studies in a systems biology approach. Whilst the emphasis is on science and technology for food safety management, it is suggested that decreases in foodborne illness will also arise from minimising human error by changing the food safety culture.

Cornell Alliance for Science has launched an initiative in which "citizen scientists" are called upon to evaluate studies on health risks of genetically modified (GM) crops and foods. The purpose is to establish whether the consensus on GM food safety claimed by the American Association for the Advancement of Science (AAAS) is supported by a review of the scientific literature. The Alliance's citizen scientists are examining more than 12,000 publication abstracts to quantify how far the scientific literature supports the AAAS's statement. We identify a number of fundamental weaknesses in the Alliance's study design, including evaluation is based only on information provided in the publication abstract; there is a lack of clarity as to what material is included in the 12,000 study abstracts to be reviewed, since the number of appropriately designed investigations addressing GM food safety are few; there is uncertainty as to whether studies of toxic effects arising from GM crop-associated pesticides will be included; there is a lack of clarity regarding whether divergent yet equally valid interpretations of the same study will be taken into account; and there is no definition of the cutoff point for consensus or non-consensus on GM food safety. In addition, vital industry proprietary biosafety data on GM crops and associated pesticides are not publicly available and is thus cannot inform this project. Based on these weaknesses in the study design, we believe it is questionable as to whether any objective or meaningful conclusion can be drawn from the Alliance's initiative.
Stable Isotope Ratio Mass Spectrometry (SIRMS) is an established technique for the determination of origin of geological, biological, chemical and physio-chemical samples/materials. With the development of highly precise mass spectrometers, the stable isotope ratio determination of hydrogen, carbon, nitrogen and oxygen have gained considerable interest in the fields of forensic science and food authentication. Natural variations in the isotopic composition of lighter elements occur due to fractionation effects, resulting in the finger printing of specific isotope ratio values that are characteristic of the origin, purity, and manufacturing processes of the products and their constituents. Forensic science uses scientific and technical methods to investigate traceable evidence of criminal acts. Stable isotope ratio mass spectrometry has been applied to numerous aspects of the forensic science. The analysis of explosives such as ammonium nitrate, gun powder and tri-nitro-toluene (TNT), cases of murder, armed robbery, drug smuggling, terrorism, arson and hit and run traffic accidents are a few of them. The main types of geological evidences in such cases are mud, soil, rocks, sand, gravel, dust particles, biological materials, organic particles and anthropogenic components. Stable isotopes are used as tools to corroborate and confirm the evidential leads in the investigation of such crimes. The variation in natural abundances of carbon and nitrogen and their isotopic ratios δ 13 C and δ 15 N can identify links between items found at crime scene with those of suspect. The paper discusses the applications of SIRMS in the field of forensic science and food adulteration research

In recent years, interactive computer simulations have been progressively integrated in the teaching of the sciences and have contributed significant improvements in the teaching-learning process. Practicing problem-solving is a key factor in science and engineering education. The aim of this study was to design simulation-based problem-solving teaching materials and assess their effectiveness in improving students' ability to solve problems in university-level physics. Firstly, we analyze the effect of using simulation-based materials in the development of students' skills in employing procedures that are typically used in the scientific method of problem-solving. We found that a significant percentage of the experimental students used expert-type scientific procedures such as qualitative analysis of the problem, making hypotheses, and analysis of results. At the end of the course, only a minority of the students persisted with habits based solely on mathematical equations. Secondly, we compare the effectiveness in terms of problem-solving of the experimental group students with the students who are taught conventionally. We found that the implementation of the problem-solving strategy improved experimental students' results regarding obtaining a correct solution from the academic point of view, in standard textbook problems. Thirdly, we explore students' satisfaction with simulation-based problem-solving teaching materials and we found that the majority appear to be satisfied with the methodology proposed and took on a favorable attitude to learning problem-solving. The research was carried out among first-year Engineering Degree students.

The chemistry of the Maillard reaction involves a complex set of steps, and its interpretation represents a challenge in basic and applied aspects of Food Science. Fluorescent compounds have been recognized as important early markers of the reaction in food products since 1942. However, the recent advances in the characterization of fluorophores' development were observed in biological and biomedical areas. The in vivo non-enzymatic glycosylation of proteins produces biological effects, promoting health deterioration. The characteristic fluorescence of advanced glycosylation end products (AGEs) is similar to that of Maillard food products and represents an indicator of the level of AGE-modified proteins, but the structure of the fluorescent groups is, typically, unknown. Application of fluorescence measurement is considered a potential tool for addressing key problems of food deterioration as an early marker or index of the damage of biomolecules. Fluorophores may be precursors of the brown pigments and/or end products. A general scheme of the Maillard reaction is proposed in this article, incorporating the pool concept. A correct interpretation of the effect of environmental and compositional conditions and their influences on the reaction kinetics may help to define the meaning of fluorescence development for each particular system.

In spite of great expectations about the potential of nanotechnology, this study shows that people are rather ambiguous and pessimistic about nanotechnology applications in the food domain. Our findings are drawn from a survey of public perceptions about nanotechnology food and nanotechnology food packaging (N = 752). Multinomial logistic regression analyses further reveal that knowledge about food risks and nanotechnology significantly influences people's views about nanotechnology food packaging. However, knowledge variables were unrelated to support for nanofood, suggesting that an increase in people's knowledge might not be sufficient to bridge the gap between the excitement some business leaders in the food sector have and the restraint of the public. Additionally, opposition to nanofood was not related to the use of heuristics but to trust in governmental agencies. Furthermore, the results indicate that public perceptions of nanoscience in the food domain significantly relate to views on science, technology, and nature.

The analysis of the responses showed that 65% of the respondents had a higher education (HE degree (BSc 29%, MSc 28%, and PhD 8%, and 20% carried out extracurricular training before entering in the job market. The main fields of study were Food Science and Technology/Engineering, followed by Agriculture, Nutrition and Health, Safety/Hygiene, and Chemical Engineering in all three levels of HE degrees. Differences in the level of degree between genders were not observed, although a higher percentage of female respondents (36% of all female respondents reported no higher qualification degree, compared to male respondents (33% of all male respondents. On the contrary, female respondents prevailed in extracurricular studies, compared to male ones. Gender, however, was a differentiating factor as far as the field of studies was concerned with female respondents prevailing in Nutrition and Health and male in Agriculture.A considerable percentage of the respondents acquired either a ΗΕ degree or had extracurricular training while working in the 1st job. Extracurricular training both before entering the job market and during work at the 1st workplace comprised mainly the topics Safety and Hygiene, Management, followed by Sensory Science, FST/E and Nutrition and Health. In addition, Marketing Science/Consumer Behaviour was also one of the main topics of company or other training during work at the 1st workplace.

Contaminants are undesirable constituents in food. They may be formed during production of a processed food, present as a component in a source material, deliberately added to substitute for the proper substance, or the consequence of poor food-handling practices. Contaminants may be chemicals or pathogens. Chemicals generally degrade over time and become of less concern as a health threat. Pathogens have the ability to multiply, potentially resulting in an increased threat level. Formal structures have been lacking for systematically generating and evaluating hazard and exposure data for bioactive agents when problem situations arise. We need to know what the potential risk may be to determine whether intervention to reduce or eliminate contact with the contaminant is warranted. We need tools to aid us in assembling and assessing all available relevant information in an expeditious and scientifically sound manner. One such tool is the International Life Sciences Institute (ILSI) Key Events Dose-Response Framework (KEDRF). Developed as an extension of the WHO's International Program on Chemical Safety/ILSI mode of action/human relevance framework, it allows risk assessors to understand not only how a contaminant exerts its toxicity but also the dose response(s) for each key event and the ultimate outcome, including whether a threshold exists. This presentation will illustrate use of the KEDRF with case studies included in its development (chloroform and Listeriaonocytogenes) after its publication in the peer-reviewed scientific literature (chromium VI) and in a work in progress (3-monochloro-1, 2-propanediol).

From production to consumption, food involves many important cultural, social, and economic activities of human societies. Yet, despite advances in science and technology...... that have modernized food production and distribution, hunger and malnutrition still threaten the health and well-being of millions of people around the world. Estimates suggest that 800 million people in ‘developing’ countries are undernourished; of these 207.6 million reside in India alone. Food security...... is affected by food availability and affordability, which in turn, is largely influenced by the state of agriculture. The pivotal importance of agriculture in the fight against hunger and poverty lies in the fact that around 2.5 billion people in developing countries live in rural areas and are engaged...
This meeting was about food science, technology and energy production. In this meeting were discussed subjects concerned food preservation and irradiation sources in economical, technological, social and research aspects.
The International Atomic Energy Agency (IAEA) today called for increased investment in a plant breeding technique that could bolster efforts aimed at pulling millions of people out of the hunger trap. IAEA scientists use radiation to produce improved high-yielding plants that adapt to harsh climate conditions such as drought or flood, or that are resistant to certain diseases and insect pests. Called mutation induction, the technique is safe, proven and cost-effective. It has been in use since the 1920s. 'The global nature of the food crisis is unprecedented. Families all around the world are struggling to feed themselves,' says Mohamed ElBaradei, Director General of the IAEA. 'To provide sustainable, long-term solutions, we must make use of all available resources. Selecting the crops that are better able to feed us is one of humankind's oldest sciences. But we've neglected to give it the support and investment it requires for universal application. The IAEA is urging a revival of nuclear crop breeding technologies to help tackle world hunger.' For decades the IAEA, in partnership with the Food and Agriculture Organization of the United Nations (FAO), has assisted its Member States to produce more, better and safer food. In plant breeding and genetics, its expertise is helping countries around the world to achieve enhanced agricultural output using nuclear technology. Already more than 3000 crop varieties of some 170 different plant species have been released through the direct intervention of the IAEA: they include barley that grows at 5000 meters (16,400 ft) and rice that thrives in saline soil. These varieties provide much needed food as well as millions of dollars in economic benefits for farmers and consumers, especially in developing countries. But with increased investment and broader application, the technology could positively impact the health and livelihood of even greater numbers of people. And as world hunger grows, the need has never been more urgent.

Explore associations between nutrition, science, and mathematics knowledge to provide evidence that integrating food/nutrition education in the fourth-grade curriculum may support gains in academic knowledge. Secondary analysis of a quasi-experimental study. Sample included 438 students in 34 fourth-grade classrooms across North Carolina and Ohio; mean age 10 years old; gender (I = 53.2% female; C = 51.6% female). Dependent variable = post-test-nutrition knowledge; independent variables = baseline-nutrition knowledge, and post-test science and mathematics knowledge. Analyses included descriptive statistics and multiple linear regression. The hypothesized model predicted post-nutrition knowledge (F(437) = 149.4, p mathematics knowledge were predictive of nutrition knowledge indicating use of an integrative science and mathematics curriculum to improve academic knowledge may also simultaneously improve nutrition knowledge among fourth-grade students. Teachers can benefit from integration by meeting multiple academic standards, efficiently using limited classroom time, and increasing nutrition education provided in the classroom. © 2018, American School Health Association.
Full Text Available Introduction: Health and food safety is one of the most important issues of nutrition science. The present study aims to examine the knowledge and attitude towards health and food safety among students of Tabriz University of Medical Sciences, Tabriz, Iran. Methods: This study was conducted through cross-sectional approach on 300 students of Tabriz University of Medical Sciences who were selected through stratified random sampling method, using a validated and reliable researcher-made questionnaire. Data were analyzed by SPSS.Results: More than 50% of students had high attitude and knowledge towards health and food safety and washing hands before cooking. Further, more than 60% of students had low attitude on other related items such as unimportance of food additives in food safety. Besides, more than 50% of students had low knowledge about best temperature to store cooked food which is between 5 to 65 °C and the most appropriate plastic containers to keep food healthy. About 87.3% of students had good knowledge about diseases that could be transmitted through food. That there was a significant relationship between students' attitude and taking courses related to health and food safety (P = 0.010. There was also a significant relationship between students' knowledge and their college (P = 0.001 and major (P = 0.020. Conclusion: Results obtained revealed that students from some colleges and some majors had low knowledge of health and food safety. It is therefore necessary to hold training programs through workshops or to include courses in the curriculum of majors that lack such credits.

The primary objective of this pilot study is to provide evidence that a budget-tailored culinary nutrition program is both appropriate and applicable to undergraduate food science students both in everyday life as well as their future health careers. Two validated programs were combined into one program in order to evaluate their combined effects: Cooking With a Chef and Cooking Matters at the Store. The secondary objective of this pilot study is to evaluate the components and reliability of a questionnaire created specifically for this pilot study. A review of past literature was written, which included culinary nutrition as a source of primary prevention, the importance of incorporating cost with culinary nutrition, and the importance of incorporating cost with culinary nutrition. Based on the literature review, it was determined that a budget-tailored culinary nutrition program was appropriate and applicable to undergraduate food science students interested in pursuing health-related careers. The pilot study design was a semi-crossover study: all four groups received the program, however, two groups were first treated as the control groups. All fifty-four participants received 5 sessions of culinary nutrition information from Cooking With a Chef, collaboratively delivered by a nutrition educator and a chef, and one session of information about shopping healthy on a budget from Cooking Matters at the Store in the form of a grocery store tour led by the nutrition educator. Three questionnaires were administered to the participants that evaluated culinary nutrition and price knowledge, cooking attitudes, and opinions of the programs' relevance to participants' everyday lives and careers. Two of the questionnaires, including a questionnaire developed specifically for the pilot study, were delivered as a pre- and post-test while the third questionnaire was delivered as a post-test. Eight random participants also partook in a focus group session led by the nutrition

Environmental risk assessment is often affected by severe uncertainty. The frequently invoked precautionary principle helps to guide risk assessment and decision-making in the face of scientific uncertainty. In many contexts, however, uncertainties play a role not only in the application of scientific models but also in their development. Building on recent literature in the philosophy of science, this paper argues that precaution should be exercised at the stage when tools for risk assessment are developed as well as when they are used to inform decision-making. The relevance and consequences of this claim are discussed in the context of the threshold of the toxicological concern approach in food toxicology. I conclude that the approach does not meet the standards of an epistemic version of the precautionary principle.

This cross-sectional survey study compared the on- and off-campus snack choices and related correlates of convenience samples of exercise science (ES) ( n = 165, M = 45%, F = 55%) and non-exercise science (NES) ( n =160, M = 43%, F = 57%) undergraduates. The hypothesis posed was that knowledge of healthy foods will not translate to healthier snack consumption by the ES students, and that the snack choices and related correlates of ES and NES students will be similar. Data were collected using self-administered questionnaires completed in classrooms (ES sample) and at high-traffic locations on-campus (NES sample). Chi-square and t-test analyses compared ES and NES students on snack correlates. Snacks consumed most often by the ES and NES students on-campus were health bars/squares ( n = 56 vs. n = 48) and savory snacks ( n = 55 vs. n = 71), and off-campus were savory snacks ( n = 60 vs. n = 71) and fruits ( n = 41 vs. n = 34). Over half of both samples believed their snack choices were a mix of unhealthy and healthy. Fruits were considered healthier snacks and chips less healthy by both samples, and fruits were the most often recommended snack. About 20% believed these choices would impact their health unfavorably, and about two thirds self-classified in the action stages for healthy snacking. Since knowledge about healthy food choices did not translate to healthy snack selection, these students would benefit from interventions that teach selection and preparation of healthy snacks on a restricted budget.

Fluorescent molecular rotors (MRs) are compounds whose emission is modulated by segmental mobility; photoexcitation generates a locally excited (LE), planar state that can relax either by radiative decay (emission of a photon) or by formation of a twisted intramolecular charge transfer (TICT) state that can relax nonradiatively due to internal rotation. If the local environment around the probe allows for rapid internal rotation in the excited state, fast non-radiative decay can either effectively quench the fluorescence or generate a second, red-shifted emission band. Conversely, any environmental restriction to twisting in the excited state due to free volume, crowding or viscosity, slows rotational relaxation and promotes fluorescence emission from the LE state. The environmental sensitivity of MRs has been exploited extensively in biological applications to sense microviscosity in biofluids, the stability and physical state of biomembranes, and conformational changes in macromolecules. The application of MRs in food research, however, has been only marginally explored. In this review, we summarize the main characteristics of fluorescent MRs, their current applications in biological research and their current and potential applications as sensors of physical properties in food science and engineering.

Full Text Available Dark chocolate (DC was originally introduced in human nutrition as a medicinal product consumable in a liquid form. Century-long efforts of food industry transformed this hardly appealing product into a valuable modern culinary delight with clear predominance of confectionery brands of DC on the market. However, current epidemiological data as well as multiple experimental and clinical observations reveal that DC consumption may have a profound effect on cardiovascular, central nervous systems, hemostasis, and lipid metabolism. However, despite of growing body of modern scientific evidence revealing medicinal properties of cocoa-based products, DC remains more gourmet culinary item than medicinal food product. Even today there are no clear dietary recommendations on consumption of cocoa flavonoids (flavanols for health purpose. Clinical trials with DC rarely include monitoring of plasma flavanol concentration in volunteers. Moreover, there is no standardized assay or any quantitative requirements for flavanol content in the commercial brands of DC. High flavanol content is often sacrificed during manufacturing for a better taste of DC due to bitterness of cocoa flavonoids. All these problems including subsequently arising ethical issues need to be addressed by joint efforts of food industry and medical science. Moreover, application of microencapsulation technology in DC manufacturing, as well as molecular selection of best flavanol producers may drastically change bioavailability of DC bioactive ingredients and DC production technology. Nevertheless, only strict causative approach, linking possible health effect of DC to its bioactive ingredients considered as nutraceuticals, may change the current landscape in nutritional research related to cocoa-based products and create a trustworthy path for their medicinal use.

The Laboratorio Didattica e Divulgazione Scientifica of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Educational and Outreach Laboratory) organized activity with kids to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. The combination of games and learning in educational activity can be a valuable tool for study of complex phenomena. Hands-on activity may help in engage kids in a learning process through direct participation that significantly improves the learning performance of children. Making learning fun motivate audience to pay attention on and stay focused on the subject. We present the experience of the hand-on laboratory "Laboratorio goloso per bambini curiosi di scienza (a delicious hands-on laboratory for kids curious about science)", performed in Frascati during the 2013 European Researchers' Night, promoted by the European Commission, as part of the program organized by the Laboratorio Didattica e Divulgazione Scientifica in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/). The hand-on activity were designed for primary schools to create enjoyable and unusual tools for learning Earth Science. During this activity kids are involved with something related to everyday life, such as food, through manipulation, construction and implementation of simple experiments related to Earth dynamics. Children become familiar with scientific concepts such as composition of the Earth, plates tectonic, earthquakes and seismic waves propagation and experience the effect of earthquakes on buildings, exploring their important implications for seismic hazard. During the activity, composed of several steps, participants were able to learn about Earth inner structure, fragile lithosphere, waves propagations, impact of waves on building ecc.., dealing with eggs, cookies, honey, sugar, polenta, flour, chocolate, candies, liquorice sticks, bread, pudding and sweets.

Coumarins are a group of phytochemicals that may be beneficial or harmful to health depending on their type and dosage and the matrix that contains them. Some of these compounds have been proven to display pro-oxidant and clastogenic activities. Therefore, in the current work, we have studied the coumarins that are present in food sources extracted from the Phenol-Explorer database in order to predict their clastogenic activity and identify the structure-activity relationships and genotoxic structural alerts using alternative methods in the field of computational toxicology. It was necessary to compile information on the type and amount of coumarins in different food sources through the analysis of databases of food composition available online. A virtual screening using a clastogenic model and different software, such as MODESLAB, ChemDraw and STATISTIC, was performed. As a result, a table of food composition was prepared and qualitative information from this data was extracted. The virtual screening showed that the esterified substituents inactivate molecules, while the methoxyl and hydroxyl substituents contribute to their activity and constitute, together with the basic structures of the studied subclasses, clastogenic structural alerts. Chemical subclasses of simple coumarins and furocoumarins were classified as active (xanthotoxin, isopimpinellin, esculin, scopoletin, scopolin and bergapten). In silico genotoxicity was mainly predicted for coumarins found in beer, sherry, dried parsley, fresh parsley and raw celery stalks. The results obtained can be interesting for the future design of functional foods and dietary supplements. These studies constitute a reference for the genotoxic chemoinformatic analysis of bioactive compounds present in databases of food composition.

The US Food and Drug Administration's (FDA's) 1992 policy statement was developed in the context of critical gaps in scientific knowledge concerning the compositional effects of genetic transformation and severe limitations in methods for safety testing. FDA acknowledged that pleiotropy and insertional mutagenesis may cause unintended changes, but it was unknown whether this happens to a greater extent in genetic engineering compared with traditional breeding. Moreover, the agency was not able to identify methods by which producers could screen for unintended allergens and toxicants. Despite these uncertainties, FDA granted genetically engineered foods the presumption of GRAS (Generally Recognized As Safe) and recommended that producers use voluntary consultations before marketing them.

The incidence of botulism in canned food in the last century is reviewed along with the background science; a few conclusions are reached based on analysis of published data. There are two primary aspects to botulism control: the design of an adequate process and the delivery of the adequate process to containers of food. The probability that the designed process will not be adequate to control Clostridium botulinum is very small, probably less than 1.0 x 10(-6), based on containers of food, whereas the failure of the operator of the processing equipment to deliver the specified process to containers of food may be of the order of 1 in 40, to 1 in 100, based on processing units (retort loads). In the commercial food canning industry, failure to deliver the process will probably be of the order of 1.0 x 10(-4) to 1.0 x 10(-6) when U.S. Food and Drug Administration (FDA) regulations are followed. Botulism incidents have occurred in food canning plants that have not followed the FDA regulations. It is possible but very rare to have botulism result from postprocessing contamination. It may thus be concluded that botulism incidents in canned food are primarily the result of human failure in the delivery of the designed or specified process to containers of food that, in turn, result in the survival, outgrowth, and toxin production of C. botulinum spores. Therefore, efforts in C. botulinum control should be concentrated on reducing human errors in the delivery of the specified process to containers of food.

There has been significant public debate about the susceptibility of research to biases of various kinds. The dialogue has extended to the peer-reviewed literature, scientific conferences, the mass media, government advisory bodies, and beyond. While biases can come from myriad sources, the overwhelming focus of the discussion, to date, has been on industry-funded science. Given the critical role that industry has played and will continue to play in the research process, the International Life Sciences Institute (ILSI) North America Working Group on Guiding Principles has, in this paper, set out proposed conflict-of-interest guidelines, regarding industry funding, for protecting the integrity and credibility of the scientific record, particularly with respect to health, nutrition, and food-safety science. Eight principles are enumerated, specifying ground rules for industry-sponsored research. The paper, which issues a challenge to the broader scientific community to address all bias issues, is only a first step; the document is intended to be dynamic, prompting ongoing discussion and refinement. The Guiding Principles are as follows. In the conduct of public/private research relationships, all relevant parties shall: 1) conduct or sponsor research that is factual, transparent, and designed objectively; according to accepted principles of scientific inquiry, the research design will generate an appropriately phrased hypothesis and the research will answer the appropriate questions, rather than favor a particular outcome; 2) require control of both study design and research itself to remain with scientific investigators; 3) not offer or accept remuneration geared to the outcome of a research project; 4) prior to the commencement of studies, ensure that there is a written agreement that the investigative team has the freedom and obligation to attempt to publish the findings within some specified time-frame; 5) require, in publications and conference presentations

Analytic advances are enabling more precise definitions of the molecular composition of key food staples incorporated into contemporary diets and how the nutrient landscapes of these staples vary as a function of cultivar and food processing methods. This knowledge, combined with insights about the interrelationship between consumer microbiota configurations and biotransformation of food ingredients, should have a number of effects on agriculture, food production, and strategies for improving the nutritional value of foods and health status. These effects include decision-making about which cultivars of current or future food staples to incorporate into existing and future food systems, and which components of waste streams from current or future food manufacturing processes have nutritional value that is worth capturing. They can also guide which technologies should be applied, or need to be developed, to produce foods that support efficient microbial biotransformation of their ingredients into metabolic products that sustain health.

Full Text Available Valorization of knowledge produced in research units has been a major challenge for research universities in contemporary societies. The prevailing forces have led these institutions to develop a “third mission”, the facilitation of technology transfer and activity in an entrepreneurial paradigm. Effective management of challenges encountered in the development of academic entrepreneurship and the associated valorization of knowledge produced by universities are major factors to bridge the gap between research and innovation in Europe.The need to improve the existing institutional knowledge valorization processes, concerning entrepreneurship and business development and the processes required were discussed.A case study was designed to describe the institutional knowledge valorization process in a food science and technology research unit and a related incubator, during a five year evaluation period that ended in 2012.The knowledge valorization processes benefited from the adoption of a structured framework methodology that led to ideas and teams from a business model generation to client development, in parallel, when possible, with an agile product/service development.Although academic entrepreneurship engagement could be improved, this case study demonstrated that stronger skills development was needed to enable the researcher to be more aware of business development fundamentals and therefore contribute to research decisions and the valorisation of individual and institutional knowledge assets. It was noted that the timing for involvement of companies in the research projects or programs varied with the nature of the research.

Full Text Available Internet databases of small molecules, their enzymatic reactions, and metabolism have emerged as useful tools in food science. Database searching is also introduced as part of chemistry or enzymology courses for food technology students. Such resources support the search for information about single compounds and facilitate the introduction of secondary analyses of large datasets. Information can be retrieved from databases by searching for the compound name or structure, annotating with the help of chemical codes or drawn using molecule editing software. Data mining options may be enhanced by navigating through a network of links and cross-links between databases. Exemplary databases reviewed in this article belong to two classes: tools concerning small molecules (including general and specialized databases annotating food components and tools annotating enzymes and metabolism. Some problems associated with database application are also discussed. Data summarized in computer databases may be used for calculation of daily intake of bioactive compounds, prediction of metabolism of food components, and their biological activity as well as for prediction of interactions between food component and drugs.

Full Text Available Theoretical and empirical research offers support for explicit instruction on metacognition and cognitive strategies as an effective way to improve L2 listening skills. This study is aimed at identifying whether both metacognition and cognitive strategies are worked on in a university-level French class on a daily basis. A second-year French-class teacher and his students (n=26 were observed during five listening-based sessions over a semester. Quantitative data was collected with regard to six dimensions of explicit metacognitive instruction of listening skills, using a teacher self-evaluation questionnaire, a student questionnaire and a structured observation. The results reveal implicit cognitive work during the pre-, while- and post-listening teaching stages. Nonetheless, strategy assessment, and the explicit teaching of metacognitive strategies for planning, monitoring, controlling and problem identifying, both remain controversial.

Full Text Available Background: Considering the significant role of consumers’ awareness about food labels in making healthy food choices, this study was designed to assess the knowledge, attitude and prac-tice of university students about food labeling.Methods: In this cross-sectional study, 332 students aged 18-25 yr in five different academic ma-jors (including Nutrition, Public Health, Health Services Administration, Paramedical and En-gineering were asked to complete an approved questionnaire contained fifteen questions. The chi-square test was applied to examine the differences across various major groups.Results: 89.2% of the students believed that food labels had effect on nutritional awareness. 77.4% were agreed with the usefulness of the food labels and 79.2% did not feel that nutrition claims on food label were truthful. For 84% of students, the expiry date and storage conditions information were the most important informational cues to appear on the food labels. From 47.6% of students who reported the use of nutrition facts label in their often or always shopping; only 32.3% used the information on labels to fit the food into their daily diet. Surprisingly, fatty acids were the least noteworthy items (1.9% on nutrition facts labels. Regarding students’ major, there was significant difference in their knowledge, attitude and practice about truth of the nutri-tion claims, using food labels and importance of health claims (P<0.05.Conclusion: Food labels were more useful tools for students and had an effect on their nutri-tional awareness. Designing and implementation of the educational programs in order to increase the level of knowledge about food labels is suggested.

Full Text Available The main goal of this paper was to conduct an exploratory study regarding consumer preference in the field of the Food Science and Technology. Two questions guided this study: Is it possible to identify a trail of crumbs concerning consumer behavior in the Food Science and Technology field? And, if that trail exists, where is it leading academia in terms of research trends of interest? A bibliometric study was conducted using an analysis software called CiteSpace. The use of this methodology ensured the impartiality of the literature review of the topic of interest. A survey of all articles indexed in Web of Science between 1993 and 2013 regarding consumer behaviour was carried out. In total, 1,786 articles were analyzed. The recent increased concern regarding consumer behavior was evident. With the USA and Spain having a significant role in driving the trail. Eight other countries that exhibited similar influences are: Italy, England, Australia, Germany, Denmark, France, Netherlands and Brazil. The research trends observed were grouped into seven major hot topics: sensory, health, safety, willingness to pay, packaging, ethics, and lifestyle/convenience. However, the development of publishing trends depended on where the research was carried out. A final suggestive finding, demonstrated that scientific knowledge does not occur in a vacuum.

Better methods of agricultural production, availability of hybrid and mutant varieties of crop plants, irrigation, fertilizers and pesticides have all helped boost up agricultural production, and famines and droughts remain restricted to a few pockets in the world. Innovative approach to step up agricultural production, especially of food crops symbolize synergy and synthesis of conventional and mutation breeding aided by modern biotechnological tools like DNA markers and gene manipulation in tune with the policy of environmental and soil conservation. It has increased the production of oil seeds in India during the last decade with a shift from groundnut and mustard to soybean and sunflower. Bhabha Atomic Research Centre (BARC), Mumbai which has strongly pursued the important societal programmes using nuclear technology in agriculture and health, has made a very significant impact on the country's agriculture by developing 27 new crop varieties mostly of oil seeds and pulses. Further, radiation processing of food, pioneered in India by BARC, is now gaining global acceptance and has opened new vistas for agriculture exports. The present symposium is dedicated to trends in research of technologies in agriculture and food sciences. The papers relevant to INIS are indexed separately

To verify if there is an agreement between speech-language pathologists and nutritionists about the classification of food textures used in hospitals and their opinions about the possible consequences of differences in this classification. This is a descriptive, cross-sectional study with 30 speech-language pathologists and 30 nutritionists who worked in 14 hospitals of public and/or private network in Belo Horizonte, Brazil. The professionals answered a questionnaire, prepared by the researchers, and classified five different foods, with and without theoretical direction. The data were analyzed using Fisher's exact and Z -tests to compare ratios with a 5% significance level. Both speech-language therapists (100%) and nutritionists (90%) perceive divergence in the classification and, 86.2% and 100% of them, respectively, believe that this difference may affect the patients' recovery. Aspiration risk was the most mentioned problem. For the general classification of food textures, most of the professionals (88.5%) suggested four to six terms. As to the terminology used in the classification of food presented without theoretical direction, the professionals cited 49 terms and agreed only in the solid and liquid classifications. With theoretical direction, the professionals also agreed in the classification of thick and thin paste. Both the professionals recognized divergences in the classification of food textures and the consequent risk of damage to patient's recovery. The use of theoretical direction increased the agreement between these professionals.

We expand upon the notion of the "credibility cycle" through a study of credibility engineering by the food industry. Research and development (R&D) as well as marketing contribute to the credibility of the food company Unilever and its claims. Innovation encompasses the development, marketing, and sales of products. These are directed towards three distinct audiences: scientific peers, regulators, and consumers. R&D uses scientific articles to create credit for itself amongst peers and regulators. These articles are used to support health claims on products. However, R&D, regulation, and marketing are not separate realms. A single strategy of credibility engineering connects health claims to a specific public through linking that public to a health issue and a food product.

This past year and a half has been one of the most unsettled periods in the history of the Livermore Laboratory. Our laboratory, like all federal laboratories, has felt the winds of change from Washington. Various committees are questioning the way in which the federal government supports scientific research and the appropriateness of certain to programs. Science and Technology Review is one of the principal mechanisms by which we inform and educate a broad readership about our research programs and accomplishments. Much of the Laboratory`s research is at the cutting edge of science and technology, making it particularly challenging to describe state-of-the-art accomplishments and their significance in widely understood terms. Our goal is that the articles presented here represent the full range of projects at Livermore and convey the challenge and excitement of working at the frontiers of science and technology.

Full Text Available Science teachers are the main professionals in schools who address health-related subjects, though food and nutrition education (FNE projects are mainly planned by health professionals, especially nutritionists. The objective of this study is to create a transdisciplinary approximation between scientific research fields and practical fields from the analysis of an integrated case study conducted in Brazilian schools. In 2011, 10 days of observation were programmed in six schools in five cities. Semi-structured interviews were carried out with different social actors and data was analyzed using the complex thinking theory and the bricolage method of educational research. Planting of vegetable gardens or projects to improve table manners during mealtimes were identified in the schools. The results describe educational approaches used by science teachers to include FNE in school activities, even when not described in the official curriculum. Health professionals can identify actions to support health education in schools starting with that already undertaken by science teachers. The successful initiatives also involved professionals with practical knowledge and experience of life.

Full Text Available Achievement badges are a form of gamification that are used in an attempt to increase user engagement and motivation in various systems. A badge is typically a graphical icon that appears as a reward for the user after reaching an achievement but that has no practical value. In this study, we describe and evaluate the use of achievement badges in the ANONYMOUS online learning environment where students solve interactive, automatically assessed exercises in a Data Structures and Algorithms course throughout the semester. We conducted an experiment where the students (N=281 were randomly divided into a treatment and a control group, with and without achievement badges. Students in the treatment group were awarded achievement badges, for example, for solving exercises on the first attempt, doing exercises early, or solving all the exercises in a round with full points. Grading was the same for both groups, i.e. collecting badges did not affect the final grade, even though the exercise points themselves did. Students’ activity in ANONYMOUS was logged in order to find out whether the achievement badges had an effect on their behavior. We also collected numerical and open-ended feedback in order to find out students’ attitudes towards the badges. Our results show that achievement badges can be used to affect students’ behavior. Statistically significant differences were observed in the time used per exercise, number of sessions, total time, and normalized total number of badges. Furthermore, the majority of the students reported being motivated by the badges. Based on our findings, achievement badges seem to be a promising method to motivate students and to encourage desired study practices.

Improving the dietary intake among different groups and population is important for improving the health status. This study determines the nutrients and food group intake as well as dietary habits among female students in Isfahan University of Medical Sciences. Two hundreds and eighty nine healthy female youths who were randomly selected among students of Isfahan University of Medical Sciences in Isfahan, Iran were enrolled. A validated semi quantitative food frequency questionnaire was used. Folate, iron, calcium and fiber intake were lower than the recommended dietary allowances (RDA) amounts (70, 76, 90, 56% of RDA, respectively). Forty five percent of the population consumed fast foods 2 times a week and 35% used the frying oils for cooking most of the time. Female youths had lower amount of some micronutrients. Consuming frying oils, hydrogenated vegetable oils, and fast food intake should be limited among this group.

Full Text Available The thesis of this paper is that the "rational fool" syndrome can be applied to mainstream public sector agricultural research that is conducted in a way that is rational in the short term, but acts against its own long-term viability. Historically, a main concern of such research has been to maximize high levels of food production together with low prices to consumers. As a result, mainstream agricultural science has ignored negative impacts or externalities, which has contributed to a crisis of credibility with the general public and politically sensitive decision makers. A long-term strategic research agenda for the public sector is being defined that is new and relevant to present efforts to integrate natural resource management and sustainable agricultural production. Such an agenda must be understood as a way of managing natural resources for the production of food and environmental services essential to human well-being. If agricultural systems are viewed and managed as parts of whole ecosystems, the key properties of complex systems that need to be taken into account will force researchers to consider long-term effects and environmental externalities. Research products will then be increasingly strategic in nature, and the research process will be "democratized" as it involves and gains the support of a broad set of stakeholders. Private sector research cannot be expected to meet this need because strategic studies of resource management are required that cannot be made exclusive or proprietary and are, in other words, public goods. Several innovative research initiatives are under way that signal opportunities for change. This paper first elaborates on this argument and then illustrates key elements of the integrated natural resource management approach, with examples of approaches that show promise as alternatives to mainstream agricultural science. Although numerous and diverse, integrated approaches manifest several properties that
Full Text Available A common subsequence is a fragment of the amino acid chain that occurs in more than one protein. Common subsequences may be an object of interest for food scientists as biologically active peptides, epitopes, and/or protein markers that are used in comparative proteomics. An individual bioactive fragment, in particular the shortest fragment containing two or three amino acid residues, may occur in many protein sequences. An individual linear epitope may also be present in multiple sequences of precursor proteins. Although recent recommendations for prediction of allergenicity and cross-reactivity include not only sequence identity, but also similarities in secondary and tertiary structures surrounding the common fragment, local sequence identity may be used to screen protein sequence databases for potential allergens in silico. The main weakness of the screening process is that it overlooks allergens and cross-reactivity cases without identical fragments corresponding to linear epitopes. A single peptide may also serve as a marker of a group of allergens that belong to the same family and, possibly, reveal cross-reactivity. This review article discusses the benefits for food scientists that follow from the common subsequences concept.
Full Text Available β-galactosidase is an enzyme with hydrolytic and transgalactosylation activity. The origin of the enzyme dictates the balance between both activities. Industrially used β-galactosidases are obtained with recombinant production from filamentus funghi Aspergillus sp. and yeasts Kluyveromyces sp. Recently thermostabile β-galactosidases have been subject of many research. The enzyme can be industrially used in free or immobilized form. Immobilization often provides better stability, reusability and lower expenses. Application of β-galactosidase is most common in food processing and nutrition, it is also used in medicine and ecology. Hydrolytic activity of the enzyme has long been used for reducing lactose content in milk, while transgalactosylitic activity is used for synthesis of products such as galactooligosaccharides, lactosucrose and others. The latter have a great potential in food industry for obtaining products with reduced lactose content and increasing of nutritional value by adding dietetic fibers such as galactooligosaccharides. Despite the potential it is vital that reaction mechanisms become better understood and optimization is in place in order to reach the usability of this enzyme at industrial level.

Full Text Available Despite the tremendous scientific and technological achievements in the production of food, human well-being has not been served to a satisfactory extent. Millions of people are literally killing themselves by excessive eating or wrong use of food, leading to obesity and nutrition-related diseases. At the same time millions of people continue to suffer from lack of food, leading to starvation, malnutrition and death, often before reaching adult age. Parallel to striving for better-safer-healthier food, the community of Food Sciences is faced with the challenge to help educate the average consumer on how to select, handle, store and use food for safe and healthy eating. The need to reshape and reform public education to better serve this task is obvious. What is also obvious is the need for medical professionals to recognize healthy eating (and exercise as the most valuable tool in preventive medical care. This perspective will concentrate on challenges and opportunities for Food Scientists/Engineers: to contribute towards a society of well-informed, self-protected, active and considerate citizens; to support public (food-related education and actively participate in the fight against obesity and nutrition-related diseases; to intervene in decision making bodies and underline the importance of education on nutrition and food; to invent avenues and possibilities to contribute to the fight against world hunger; and all in all, to contribute towards a healthier world, a world that will not be split between hunger and obesity.

The National Institute of Food and Agriculture within the U.S. Department of Agriculture provides leadership, capacity, and funds to support the continuing development of a safe and competitive agricultural system. Many of the agency's educational programs are led by the Division of Community and Education (DOCE). These programs span agricultural education, enhancing agricultural literacy through both formal and nonformal education. Here, we have highlighted funding opportunities within DOCE that enhance agricultural education and literacy by supporting the improvement of students' critical communication, leadership skills, and experiential learning opportunities. Some of these programs include opportunities for which students can apply, while others focus on faculty applications. Opportunities faculty can apply for may support student-recruitment and student-retention techniques, curriculum development, innovative teaching methods, and institutional capacity-building programs. Overall, these programs foster a diverse workforce in agricultural science that matches the increasing diversity of the country. © 2016 J. E. Parker and D. J. Wagner.

Full Text Available Over the last 6 years, a coordinated “healthy corner store” network has helped an increasing number of local storeowners stock healthy, affordable foods in Camden, New Jersey, a city with high rates of poverty and unemployment, and where most residents have little or no access to large food retailers. The initiative’s funders and stakeholders wanted to directly engage Camden residents in evaluating this effort to increase healthy food access. In a departure from traditional survey- or focus group-based evaluations, we used an evidence-based community-engaged citizen science research model (called Our Voice that has been deployed in a variety of neighborhood settings to assess how different features of the built environment both affect community health and wellbeing, and empower participants to create change. Employing the Our Voice model, participants documented neighborhood features in and around Camden corner stores through geo-located photos and audio narratives. Eight adult participants who lived and/or worked in a predefined neighborhood of Camden were recruited by convenience sample and visited two corner stores participating in the healthy corner store initiative (one highly-engaged in the initiative and the other less-engaged, as well as an optional third corner store of their choosing.

The department of Physics of the University of Glasgow was concerned about losing students after the end of the level 1 Physics course. The current research project started as an attempt to find out the reasons for this, but moved to investigate attitudes towards Physics at several stages during secondary school and attitudes towards science with primary pupils. Analyses of factors, which influence students' intentions towards studying Physics, were performed against the background of the Theory of Planned Behaviour, which interprets people's behaviour by considering three factors: attitude towards behaviour (advantages or disadvantages of being involved in the behaviour, e.g. studying Physics for Honours); subjective norm (approval or disapproval of important people towards engaging in the behaviour, e.g. parents, teacher, general norms of the society); perceived behavioural control (skills, knowledge, cooperation of others, abilities, efforts required to perform the behaviour). Analysis of these factors revealed some reasons for students' withdrawal from Physics after level 1 and pointed to factors which may facilitate students' persistence in the subject. A general analysis of level 1 and level 2 students' attitudes towards different aspects of the university Physics course revealed that the level 1 students' attitudes towards their university course of lectures and course of laboratories tended to be negatively polarised. Recommendations were suggested on the basis of the gathered evidence about how to make students' experience in university Physics more satisfactory for them. The data obtained from the separate analyses of females' and males' attitudes towards university Physics course have showed that attitudes of females and males were similar. The only significant difference between level 1 females and males was found to be the perceived behavioural control factor (students' attitudes towards course difficulty, attitudes towards work load in the course

To explore the common sense knowledge that consumers, vendors and producers hold of "natural foods". The focus was on common knowledge because this is infrequently explored in social psychology where most studies focus on the implementation of scientific knowledge. The focus was on natural foods because the naturalness of foods seems to be one of the particular concerns that current consumers have about today's food market and because a specific natural food preference was observed in the contexts of study. Fifty-seven informants in a rural context and 58 informants in an urban context participated in either a free association study or an interview study. Data content were analyzed. In the urban context natural foods obtain their significance in the relationship between food and the self-concept; eating natural (or good) food is a task that requires effort and attitude, and foods obtain a moral value. In the rural context natural foods obtain their significance as an expression of a social and cultural system of interdependence that establishes practices and customs that have a long history in the community. It is suggested that these common knowledge systems are related to practical challenges that are particular to the informants' context and that the structure of their common sense knowledge systems depend on the mediation of the flow of scientific knowledge and technological knowledge in each context.

Full Text Available This study focuses on the development of speaking skills in intermediate and lower level university classes through the simplified format of debates. The aim of this paper is to describe teaching observations with special attention given to the preparatory stages, strengths and challenges of simplified debate faced by both the teacher and the students. Observations were made while teaching speaking through simple debate to 19 - 20 year-old-students of general English at the Czech University of Life Sciences Prague in intermediate and lower level classes. By describing the methods and procedures used to engage in debates, this paper aims to enrich pedagogical methods for effectively teaching speaking skills and thus serve ESL teachers at large. By contextualizing debate within a milieu larger than the ESL classroom, this study also accesses possibilities for further application of simplified debate to heighten training for other subjects, while drawing upon the democratic context supported by debate.

Animal production and health (APH) is an important sector in the world economy, representing a large proportion of the budget of all member states in the European Union and in other continents. APH is a highly competitive sector with a strong emphasis on innovation and, albeit with country to country variations, on scientific research. Proteomics (the study of all proteins present in a given tissue or fluid - i.e. the proteome) has an enormous potential when applied to APH. Nevertheless, for a variety of reasons and in contrast to disciplines such as plant sciences or human biomedicine, such potential is only now being tapped. To counter such limited usage, 6 years ago we created a consortium dedicated to the applications of Proteomics to APH, specifically in the form of a Cooperation in Science and Technology (COST) Action, termed FA1002--Proteomics in Farm Animals: www.cost-faproteomics.org. In 4 years, the consortium quickly enlarged to a total of 31 countries in Europe, as well as Israel, Argentina, Australia and New Zealand. This article has a triple purpose. First, we aim to provide clear examples on the applications and benefits of the use of proteomics in all aspects related to APH. Second, we provide insights and possibilities on the new trends and objectives for APH proteomics applications and technologies for the years to come. Finally, we provide an overview and balance of the major activities and accomplishments of the COST Action on Farm Animal Proteomics. These include activities such as the organization of seminars, workshops and major scientific conferences, organization of summer schools, financing Short-Term Scientific Missions (STSMs) and the generation of scientific literature. Overall, the Action has attained all of the proposed objectives and has made considerable difference by putting proteomics on the global map for animal and veterinary researchers in general and by contributing significantly to reduce the East-West and North-South gaps

Full Text Available Food scientists and technologists are actively engaged in examining and developing nanotechnologies for applications such as novel functional ingredients and nutrient delivery systems, safety testing, packaging, and authenticity/authentication at an ever-increasing pace. However, before these new products/technologies are commercialised, rigorous safety testing and risk/benefit analysis are required to ensure that public and environmental concerns are addressed. This review provides an overview of food nanoscience and technology including a brief history, education, definitions pertaining to policy and regulation, and applications. The most recent findings and advances are emphasised, focussing on bioactives' delivery. In addition, proposed directions in the area of nano-based targeting of pathogens for food safety as well as medical foods are discussed. As food nanoscience and technology has been extensively reviewed in recent years, specific case examples will be limited to those reported within the past year.

Low enrolment in undergraduate level physics programmes has drawn the attention of the relevant disciplines, education policy-makers, and researchers worldwide. Many reports released during the previous decades attempt to identify the factors that attract young people to study science, but only few of them focus explicitly on physics. In Greece, in contrast to many other countries, physics departments are overflowing with young students. However, there are two categories of students: those for whom physics was the optimal choice of a programme ("choosers") and those for whom physics was an alternative choice that they had to settle for. We suggest that the latter category be called "nearly-choosers," in order to be differentiated from choosers as well as from "non-choosers," namely those candidates that did not apply to a physics programme at all. We are interested in the factors that attract high school students to study physics and the differences (if any) between choosers and nearly-choosers. A newly formed questionnaire was distributed within a Greek physics department (University of Patras), and the students' responses (n = 105) were analysed with exploratory factor analysis and specifically principal component analysis so as to extract broad factors. Three broad factors have arisen: school-based, career, and informal learning. The first two factors proved to be motivating for pursuing a degree in physics, while the third factor appeared to have a rather indifferent association. t tests and Pearson correlations indicated mild differentiations between choosers and nearly-choosers that pertain to school-based influences and informal learning.

Eduardo Primo Yúfera was the founder and director of the Instituto de Agroquímica y Tecnología de Alimentos (IATA, 1957-1974) until he was appointed president of the Consejo Superior de Investigaciones Científicas (CSIC). His aim to publicize food science led him to create the Revista de Agroquímica y Tecnología de Alimentos in 1961, the forerunner of this journal, Food Science and Technology International, which he directed until 1977. Of his scientific output, 50% has been published in this journal. He is considered to be the promoter and exponent of Food Science and Technology and Chemical Ecology in Spain as well as the instigator of the country's innovation model (R&D and innovation). In his work, he was able to combine basic research excellence and socially relevant applied research to move both science and society forward. He was an example and inspiration to many colleagues and followers. The aim of this study is to highlight the influence and importance of Primo Yúfera in the formation, development and consolidation of the journal Revista de Agroquímica y Tecnología de Alimentos, and to appraise his scientific contribution to this journal.

Science and innovation are important components underpinning the agricultural and agri-food system in Canada. Canada's vast geographical area presents diverse, regionally specific requirements in addition to the 21st century agricultural challenges facing the overall sector. As the broader needs of the agricultural landscape have evolved and will continue to do so in the next few decades, there is a trend in place to transition towards a sustainable bioeconomy, contributing to reducing greenhouse gas emission and our dependency on non-renewable resources. We highlight some of the key policy drivers on an overarching national scale and those specific to agricultural research and innovation that are critical to fostering a supportive environment for innovation and a sustainable bioeconomy. As well, we delineate some major challenges and opportunities facing agriculture in Canada, including climate change, sustainable agriculture, clean technologies, and agricultural productivity, and some scientific initiatives currently underway to tackle these challenges. The use of various technologies and scientific efforts, such as Next Generation Sequencing, metagenomics analysis, satellite image analysis and mapping of soil moisture, and value-added bioproduct development will accelerate scientific development and innovation and its contribution to a sustainable and prosperous bioeconomy.

The Institute of Sciences of Food Production of CNR (National Research Council) has been designated to perform scientific studies in the postharvest field; they mainly aim at extending the life of horticultural commodities, maintaining their quality during storage and limiting fruit losses during the marketing period. The scientific work of the Institute concerns fruit and vegetable products, both fresh and minimally transformed. Experimental research on these commodities aims at providing process parameters (temperature, relative humidity, atmosphere) to managers of packinghouses, in order to have efficient cold storage. Another research field regards pathogen control for the purpose of maintaining product healthiness and at the same time of avoiding environmental pollution. Particularly in this field, research on commonly used compounds and the screening of new ones in order to prevent pathogen diseases are carried out with International protocols, contemporarily with other Countries. Surveys are completed with wide-reaching studies on alternative systems such as physical methods (thermotherapy, UV rays, curing), biological control (essential oils and antagonist microorganisms) and with GRAS (Generally Recognized As Safe) compounds, harmless for the consumer and the environment. A great deal of research is carried out in order to examine physiological phenomena, particularly during ripening and senescence periods of the fruit and aspects connected with quality. In twenty-five years of activity, almost five hundred papers have been issued illustrating technological innovations [it
Enormous quantities of food and agricultural produce are spoiled by microbial activity, which is a major challenge to food security today. Besides, contamination of foods by pathogens or their toxins pose serious problems affecting food safety worldwide. Development of cost effective, reliable, and user friendly methods for detection and identification of microbial pathogens has always remained a challenge in microbiology. Microbial research has also aided development of probiotics, prebiotics and nutraceuticals, which are important for health. The objective of the symposium was to address and dwell upon the recent advances in some of the mentioned research areas pertaining to microbiology of food, agriculture, health and environment. The major themes of the symposium were: Adaptation to Stresses, Host-Pathogen Interactions, Sustainable Agriculture, Food Safety, Food Security and Nutrition, Environmental Microbiology etc. Papers relevant to INIS are indexed separately
Full Text Available Food-borne pathogens are the most important thing cause of illness and death in developing countries. Food safety is essential for central university kitchens because of the high number of meals served every day. These central university kitchen systems are of special interest as students are at relatively high-risk of developing serious complications from exposure to food bacterial contamination hazards. A total of 144 samples of cooked foods, collected in winter and summer 2015 from the restaurants of Tehran University of Medical Sciences, were studied to determine the microbiological quality of these products. Results were analyzed through SPSS 22.0 and t-test. According to coliform count, the highest rate of contamination was in Kebab (1.17×102 CFU/g and lowest was in fish (0.8×102 CFU/g and also the highest rate of contamination of Escherichia coli (E.coli was in Kebab (6 samples, and the lowest contamination level was in fish and in this regard no sample was reported to be positive. According to staphylococcus aureus, the highest contamination rate was in rice (0.97×102 CFU/g and lowest was in fish (0.63×102 CFU/g. Kebab had the highest contamination of coliforms and staphylococcus aureus (S. aureus in summer. None of the tested samples was confirmed with respect to salmonella, clostridium perfringens and staphylococcus aureus. Among the foods served in the university restaurants, Kebab had the highest bacterial contamination and fishes the lowest. Improved methods of cooking and food processing, prevention of secondary bacterial contamination, continuous monitoring and surveillance of food processing are the most important measures to prevent food contamination.
Full Text Available Regarding to the importance of food habits and the probable role of obesity in dental caries, this study was done to assess the relationship between teeth decay index in children and body mass index, and food habits in dentistry clinic of Tabriz university of medical sciences. Materials and Methods: In this cross-sectional analytic study 202 children aged 3-12 years old were selected randomly. For assessing dental caries, decayed, missed, and filled teeth index and for evaluating food habits, semi quantitative food frequency questionnaire were used. Data were analyzed using Correlation test and Regression analysis. Results: The overall mean of decayed, missed, and filled teeth index in the children of this study was 7.61±3.80. There were significant reverse correlations between this index and age (r = -0.176, and fruit consumption (r = -0.155 (P0.05. Considering the last regression model, age, mother job, and frequency of nuts consumption were significant predictors for decayed teeth number. Conclusion: The results of this study indicated that high fruit consumption was associated with less dental caries and among foods which were evaluated, consumption of nuts was significant predictor for decayed teeth number.

Contemporary animal agriculture is increasingly criticized on ethical grounds. Consequently, current policy and legislative discussions have become highly controversial as decision makers attempt to reconcile concerns about the impacts of animal production on animal welfare, the environment, and on the efficacy of antibiotics required to ensure human health with demands for abundant, affordable, safe food. Clearly, the broad implications for US animal agriculture of what appears to be a burgeoning movement relative to ethical food production must be understood by animal agriculture stakeholders. The potential effects of such developments on animal agricultural practices, corporate marketing strategies, and public perceptions of the ethics of animal production must also be clarified. To that end, it is essential to acknowledge that people's beliefs about which food production practices are appropriate are tied to diverse, latent value systems. Thus, relying solely on scientific information as a means to resolve current debates about animal agriculture is unlikely to be effective. The problem is compounded when scientific information is used inappropriately or strategically to advance a political agenda. Examples of the interface between science and ethics in regards to addressing currently contentious aspects of food animal production (animal welfare, antimicrobial use, and impacts of animal production practices on the environment) are reviewed. The roles of scientists and science in public debates about animal agricultural practices are also examined. It is suggested that scientists have a duty to contribute to the development of sound policy by providing clear and objectively presented information, by clarifying misinterpretations of science, and by recognizing the differences between presenting data vs. promoting their own value judgments in regard to how and which data should be used to establish policy. Finally, the role of the media in shaping public opinions
Though not a very traditional career path for food scientists, one option is to go into business for yourself by starting a food business. Food business entrepreneurship is a difficult career that entails long work hours, extensive decision making, and tasks that require knowledge beyond food science. However, there is high potential for rewards, including financial rewards, career progression, and personal flexibility.

A new booklet 'Science Serving People' features stories about how IAEA-supported projects are making a difference in many poorer countries. The stories describe applications of nuclear science and technology that are being used through technical cooperation channels to overcome challenges of water scarcity, food shortage, malnutrition, malaria, environmental degradation and many other problems. They also illustrate how the complementary development, safety, and security initiatives of the IAEA are fostering atoms for peace in the developing world. Extreme poverty and deprivation remain a problem of monumental proportions at the dawn of the 21st century, notes IAEA Director General Mohamed ElBaradei in the booklet's Introduction. Through effective partnerships, collaborative research, and strategic direction, the IAEA is contributing to global efforts to help the poor. IAEA programmes have entered an important phase, he said, in which scientific contributions to Member States are yielding very sizeable human benefits. It's clear that science and technology must be better mobilized to meet the needs of the poor, emphasizes Jeffrey Sachs, Director of the Earth Institute at Columbia University, USA, and Special Advisor to UN Secretary-General Kofi Annan. The UN agencies, such as the IAEA, have a great role to play, he says in the booklet's Foreword. This is especially so, he points out, if they act as a bridge between the activities of advanced- country and developing country scientific centres, and if they help to harness the advances of world science for the poor as well as the rich. The bottom line, he concludes, is that rich countries should expand support for those United Nations organizations that can help in solving the unique problems confronting the world's poorest peoples. The booklet features stories on managing water resources, promoting food security, focusing science on health problems, new tools for environmental management, and strengthening nuclear

The Inflammatory bowel diseases, Crohn's disease and ulcerative colitis, are debilitating conditions, characterised by lifelong sensitivity to certain foods, and often a need for surgery and life-long medication. The anti-inflammatory effects of long chain omega-3 polyunsaturated acids justify their inclusion in enteral nutrition formulas that have been associated with disease remission. However, there have been variable data in clinical trials to test supplementary omega-3 polyunsaturated fatty acids in inducing or maintaining remission in these diseases. Although variability in trial design has been suggested as a major factor, we suggest that variability in processing and presentation of the products may be equally or more important. The nature of the source, and rapidity of getting the fish or other food source to processing or to market, will affect the percentage of the various fatty acids, possible presence of heavy metal contaminants and oxidation status of the various fatty acids. For dietary supplements or fortified foods, whether the product is encapsulated or not, whether storage is under nitrogen or not, and length of time between harvest, processing and marketing will again profoundly affect the properties of the final product. Clinical trials to test efficacy of these products in IBD to date have utilised the relevant skills of pharmacology and gastroenterology. We suggest that knowledge from food science, nutrition and engineering will be essential to establish the true role of this important group of compounds in these diseases.

Genetic diversity underlies the improvement of crops by plant breeding. Landraces of tomato (Solanum lycopersicum L.) can contain valuable alleles not common in modern germplasms. The aim was to measure genetic diversity present in 47 most common tomato varieties grown in Italy, 35 were varieties used for processing and 12 were landraces considered "salad varieties". Furthermore, we demonstrated the possibility that the variety traceability can be extended through the entire production chain. Diversity was measured using 11 microsatellite markers and 94 genotypes. Among the markers used, a total of 48 alleles were detected. A dendrogram based on total microsatellite polymorphism grouped 47 varieties into three major clusters at 0.75 similarity coefficient, differentiating the modern varieties from tomatoes landraces. The DNA markers developed confirmed the possibility to support the genotype identification all along the tomato production chain. The number of alleles and genotypes identified in the present work is the largest considering papers on food traceability.
Nanoscience and nanotechnology have had a great impact on the food industry. They have increased the nutritional and functional properties of a number of food products and have aided in food preservation through the addition of antimicrobials or the reduction of water activity. These and many other applications have emerged in recent years to transform food science and technology. This book proposes to look at some of these applications and their effect on food production and innovation.
Full Text Available The aim of this review is to discuss the definition of food peptidomics and highlight the role of this approach in food and nutrition sciences. Similar to living organisms, food peptidome may be defined as the whole peptide pool present in a food product or raw material. This definition also covers peptides obtained during technological processes and/or storage. The area of interest of food peptidomics covers research concerning the origin of peptidome, its dynamic changes during processing and/or storage, the influence of its presence, the composition and changes in the pool of peptides on the properties of food products or raw materials as well as the methods applied in research into this group of compounds. The area of interests of food peptidomics would include biological activity, functional properties, allergenicity, sensory properties and information on the product or resource authenticity and origin as well as its history and relationships. Research methods applied in food peptidomics, with special emphasis on computational methods, are also summarized.

The urbanisation, technical changes, and the industrialisation of the food systems on one hand and increased income and changes in lifestyles on the other hand transform the way food is produced, marketed and consumed - those changes call for changes in the nature of food policy. Concerns over food...... safety have become an important driver of reform of food policy. In particular, the BSE crisis in 1996 had a significant impact on the formulation of a change in food safety policy in the EU. The White Paper on Food Safety was prepared by the EU commision as a response to the BSE scandal as the EU felt...... a need for restablishing public confidence in its food supply, its food science, its laws and its food control. In addition, the White Paper on Food Safety points towards a farm to fork policy in that 'as the food production chain is becoming increasingly complex, the health of consumers can ony...

The paper introduces the empirical science of 'mind genomics', whose objective is to understand the dimensions of ordinary, everyday experience, identify mind-set segments of people who value different aspects of that everyday experience, and then assign a new person to a mind-set by a statistically appropriate procedure. By studying different experiences using experimental design of ideas, 'mind genomics' constructs an empirical, inductive science of perception and experience, layer by layer. The ultimate objective of 'mind genomics' is a large-scale science of experience created using induction, with the science based upon emergent commonalities across many different types of daily experience. The particular topic investigated in the paper is the experience of healthful snacks, what makes a person 'want' them, and the dollar value of different sensory aspects of the healthful snack.

Students' opinions about the degree of impact, status, and socio-cognitive viability with the utilization of the emerging three-dimensional (3D) computer-generated technologies may vary. Indisputably, 3D technology-enhanced environments have provided considerable benefits and affordances to the contemporary e-Education. In these circumstances, virtual worlds (VWs) like second life (SL) have generally intensified with an extensive perpetuation and penetration of innovative performances that encapsulated or enacted from the vast majority of higher education fields. At the same time, there is growing widespread recognition of reasons affecting the high or low degree of students' engagement in online and blended course delivery methods held in 3D VWs. Notwithstanding that most notable studies have disclosed SL functional capabilities from a plethora of pilot case studies, however, it is still lacking an experiential-based research approach to determine the degree of students' engagement in blended and online courses at university level through SL. The present comparative study explores students' engagement overall as a multidimensional construct consisting of emotional, behavioral, and cognitive factors. One hundred and thirty-five undergraduate and postgraduate students in almost identical blended and online instructional conditions held in SL took part in this project. Preliminary results have decoded students' satisfaction for both methods, despite the fact that the voluntary sample composed of different educational disciplines. The quantitative analysis showed that postgraduate students of the online course had more positive results and the degree of engagement significantly increased compared to those who enrolled with the blended course delivery method. The instructional affordances from the utilization of SL were the collaborative climate between users (instructor and students) who eliminated various intractable boundaries which were predominantly observed by

Full Text Available Undergraduate courses provide valuable opportunities to train and empower students with the knowledge, skills, and motivation to advance society in more sustainable directions. This article emphasizes the value of bridging primary scientific research with undergraduate education through the presentation of an integrated experiential learning and primary research model called Farm-based Authentic Research Modules in Sustainability Sciences (FARMS. FARMS are collaboratively designed with agricultural stakeholders through a community needs assessment on pressing food system issues and opportunities with the objective for faculty and students to jointly identify evidence-based management solutions. We illustrate the implementation of FARMS in an undergraduate course in Ecological Agriculture at Dartmouth College, NH where students assessed various agroecological solutions for managing plant vitality, weeds, soil quality, pests, pollinators, and biodiversity at the Dartmouth Organic Farm. Student reflections indicate that the FARMS course component was beneficial for understanding agroecological theories and concepts while also motivating involvement in sustainability sciences despite the challenges of primary research. Educator reflections noted that the FARMS pedagogical approach facilitated achieving course objectives to develop students’ ability for systems thinking, critical thinking, and interdisciplinarity while fostering students’ collaboration skills and overall motivation for creating change. Adopting the FARMS model should enable faculty in the sustainability sciences to serve as bridges between the learning, practicing, and scientific communities while supporting educational programming at student and community farms. Ultimately, it is expected that the implementation of FARMS will increase student capacity and prepare the next generation of leaders to address complex challenges of the food system using an evidence-based approach.

The Earth sciences comprises many fascinating topics that is teached to different age level pupils/students in order to bring hard core science closer to their daily life. With developing possibilities in IT, multimedia overall electronic sector the teachers/lecturers have continuous possibilities to accomplish novel approaches and utilize new ideas to make science more interesting for students in all ages. Emerging, from personal experiences, the teaching of our surrounding Environment can be very enjoyable. In our everyday life the SOIL remains invisible. The soil is covered by plant cover which makes the topic somewhat in distant that is not "visible" to an eye and its importance is underestimated. In other hand, the SOIL is valuable primary resource for food production and basis of life for healthy environment. From several studies have found that because its complications, SOIL related topics are not very often chosen topic for course or diploma works by students. The lower-school students are very open to environmental topics accordingly to the grades. Here, the good results can be obtained through complimentary materials creation, like story telling and drawing books and puzzles. The middle/ and upper/school students will experience "real science" being able to learn what the science is about which often can play a important role on making choices for future curriculum completion at university level. Current presentation shares the ideas of selected methods that had showed successful results on different Earth Science topics teaching (biodiversity, growing substrates, green house gas emissions). For some ideas the presentation introduces also the further developmental possibilities to be used in teaching at Tomorrows Classroom.

Student participation and the use of active methodologies in classroom learning are being increasingly emphasized. The use of intelligent systems can be of great help when designing and developing these types of activities. Recently, emerging disciplines such as 'educational data mining' and 'learning analytics and knowledge' have provided clear examples of the importance of the use of artificial intelligence techniques in education. The main objective of this study was to gather expert opinions regarding the benefits of using complementary methods that are supported by intelligent systems, specifically, by intelligent information access systems, when processing texts written in natural language and the benefits of using these methods as companion tools to the learning activities that are employed by biomedical and health sciences teachers. Eleven teachers of degree courses who belonged to the Faculties of Biomedical Sciences (BS) and Health Sciences (HS) of a Spanish university in Madrid were individually interviewed. These interviews were conducted using a mixed methods questionnaire that included 66 predefined close-ended and open-ended questions. In our study, three intelligent information access systems (i.e., BioAnnote, CLEiM and MedCMap) were successfully used to evaluate the teacher's perceptions regarding the utility of these systems and their different methods in learning activities. All teachers reported using active learning methods in the classroom, most of which were computer programs that were used for initially designing and later executing learning activities. All teachers used case-based learning methods in the classroom, with a specific emphasis on case reports written in Spanish and/or English. In general, few or none of the teachers were familiar with the technical terms related to the technologies used for these activities such as "intelligent systems" or "concept/mental maps". However, they clearly realized the potential applicability of such

Full Text Available Alzheimer’s Disease (AD is the leading cause of dementia. Epidemiological studies suggest that AD is linked with poor status of nutrients including DHA, B-vitamins and the vitamins E and C. Ongoing neurodegeneration, particularly synaptic loss, leads to the classical clinical features of AD namely, memory impairment, language deterioration, and executive and visuospatial dysfunction. The main constituents of neural and synaptic membranes are phospholipids. Supplemenation of animals with three dietary precursors of phospholipids namely, DHA, uridine monophosphate and choline, results in increased levels of brain phospholipids, synaptic proteins, neurite outgrowth, dendritic spines formation (i.e. the anatomical precursors of new synapses and an improvement in learning and memory. Other nutrients act as co-factors in the synthesis pathway of neuronal membranes. For example B-vitamins are involved in methylation processes, thereby enhancing the availability of choline as a synaptic membrane precursor. A multi-nutrient concept that includes these nutrients may improve membrane integrity, thereby influencing membrane-dependent processes such as receptor function and amyloid precursor protein (APP processing, as shown by reduced amyloid production and amyloid β plaque burden, as well as toxicity. Together, these insights provided the basis for the development of a medical food for patients with AD, Souvenaid®, containing a specific combination of nutrients (Fortasyn™ Connect and designed to enhance synapse formation in AD. The effect of Souvenaid on memory and cognitive performance was recently assessed in a proof-of-concept study, SOUVENIR I, with 212 drug-naïve mild AD patients (MMSE 20-26. This proof-of-concept study demonstrated that oral nutritional supplementation with Souvenaid® for 12 weeks improves memory in patients with mild AD. To confirm and extend these findings, we have designed and initiated three additional studies. Two of

In the public discussion of genetically modified (GM) food the representations of science as a social good, conducted in the public interest to solve major problems are being subjected to intense scrutiny and questioning. Scientists working in these areas have been seen to struggle for the position of science in society. However few in situ studies of how the debate about science appears in learning situations at the university level have been undertaken. In the present study an introductory course in biotechnology was observed during one semester, lectures and small group supervision concerning GM food were videotaped and student's reports on the issue were collected. The ethnographic approach to Discourse analysis was conducted by means of a set of carefully selected and representative observations of how a group of students learn to argue and appropriate views held in the Discourse they are enculturated into. While socio-scientific issues (SSIs) are often associated with achieving scientific literacy in terms of "informed decisions" involving "rational thought and Discourse" this study shows that SSI in practice, in the context studied here, is primarily concerned with using scientific language to privilege professional understandings of GMOs and discredit public worries and concerns. Scientific claims were privileged over ethical, economical and political claims which were either made irrelevant or rebutted. The students were seen to appropriate a Discourse model held in the biotechnological community that public opposition towards GMO is due to "insufficient knowledge". The present study offers insights into biotechnology students' decision making regarding socio-scientific issues, while also demonstrating the utility of Discourse analysis for understanding learning in this university context. Implications for reflection on the institutional Discourse of science and teaching of controversial issues in science are drawn and the study contributes to the
Contributions of processed foods to dietary intake in the US from 2003-2008: a report of the Food and Nutrition Science Solutions Joint Task Force of the Academy of Nutrition and Dietetics, American Society for Nutrition, Institute of Food Technologists, and International Food Information Council.

Processed foods are an integral part of American diets, but a comparison of the nutrient contribution of foods by level of processing with the recommendations of the Dietary Guidelines for Americans regarding nutrients to encourage or to reduce has not been documented. The mean reported daily dietary intakes of these nutrients and other components were examined among 25,351 participants ≥2 y of age in the 2003-2008 NHANES to determine the contribution of processed food to total intakes. Also examined was the percent contribution of each nutrient to the total reported daily nutrient intake for each of the 5 categories of food that were defined by the level of processing. All processing levels contributed to nutrient intakes, and none of the levels contributed solely to nutrients to be encouraged or solely to food components to be reduced. The processing level was a minor determinant of individual foods' nutrient contribution to the diet and, therefore, should not be a primary factor when selecting a balanced diet.

The purpose of this study was to determine the effects of a microcycle (4 weeks) combined rugby conditioning plyometric compared with a nonplyometric rugby conditioning program on selected physical and motor performance components and anthropometric measurements of university-level rugby players. Players (18.94 ± 0.40 years) were assigned to either a control (n = 16) or experimental group (n = 19) from the U/19 rugby teams of the North-West University (South Africa). Twenty-six direct and indirect anthropometric measurements were taken, and the players performed a battery of 5 physical and motor performance tests before and after a microcycle (4 week) combined rugby conditioning plyometric (experimental group) and a nonplyometric rugby conditioning program (control group). The dependent t-test results showed that the control group's upper-body explosive power decreased significantly, whereas the stature, skeletal mass, and femur breadth increased significantly from pre- to posttesting. The experimental group showed significant increases in wrist breadth, speed over 20 m, agility, and power and work measurements of the Wingate anaerobic test (WAnT). Despite these results, the independent t-test revealed that speed over 20 m, average power output at 20 seconds, relative work of the WAnT, and agility were the only components of the experimental group that improved significantly more than the control group. A microcycle combined rugby conditioning plyometric program therefore leads to significantly bigger changes in selected physical and motor performance components of university-level rugby players than a nonplyometric rugby conditioning program alone. Based on these findings, coaches and sport scientists should implement 3 weekly combined rugby conditioning plyometric programs in rugby players' training regimens to improve the players' speed, agility, and power.

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.

Most international health-related standards are voluntary per se. However, the incorporation of international standard-making into WTO agreements like the SPS Agreement has drastically changed the status and effectiveness of the standards. WTO members are urged to follow international standards, even when not required to comply fully with them. Indeed, such standards have attained great influence in the trade system. Yet evidence shows that the credibility of the allegedly scientific approach of these international standard-setting institutions, especially the Codex Alimentarius Commission (Codex) governing food safety standards, has been eroded and diluted by industrial and political influences. Its decision-making is no longer based on consensus, but voting. The adoption of new safety limits for the veterinary drug ractopamine in 2012, by a very close vote, is simply another instance of the problematic operations of the Codex. These dynamics have led skeptics to question the legitimacy of the standard setting body and to propose solutions to rectify the situation. Prior WTO rulings have yet to pay attention to the defect in the decision-making processes of the Codex. Nevertheless, the recent Appellate Body decision on Hormones II is indicative of a deferential approach to national measures that are distinct from Codex formulas. The ruling also rejects the reliance on those experts who authored the Codex standards to assess new measures of the European Community. This approach provides an opportunity to contemplate what the proper relationship between the WTO and Codex ought to be. Through a critical review of WTO rulings and academic proposals, this article aims to analyze how the WTO ought to define such interactions and respond to the politicized standard-making process in an optimal manner. This article argues that building a more systematic approach and normative basis for WTO judicial review of standard-setting decisions and the selection of technical

Full Text Available Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy. Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

Ill health in early life has a significant negative impact on school grades, grade repetition, educational level, and labor market outcomes. However, less is known about qualitative socio-economic consequences of a health shock in childhood or adolescence. We investigate the relationship between onset of type 1 diabetes up to age 15 and the probability of choosing and completing a health-oriented path at upper secondary and university level of education. We analyze the Swedish Childhood Diabetes Register, the National Educational Register, and other population registers in Sweden for 2756 people with type 1 diabetes and 10,020 matched population controls. Educational decisions are modeled as unsorted series of binary choices to assess the choice of educational field as a potential mechanism linking early life health to adult outcomes. The analyses reject the hypothesis of no systematic differences in choice of educational field between people with and without type 1 diabetes at both levels. The results are robust to selection on ability proxies and across sensitivity analysis. We conclude that the observed pro health-oriented educational choices among people with type 1 diabetes in our data are consistent with disease onset in childhood and adolescence having qualitative impact on life-course choices.

We analyze the Swedish Childhood Diabetes Register, the National Educational Register, and other population registers in Sweden for 2756 people with type 1 diabetes and 10,020 matched population controls. Educational decisions are modeled as unsorted series of binary choices to assess the choice of educational field as a potential mechanism linking early life health to adult outcomes. The analyses reject the hypothesis of no systematic differences in choice of educational field between people with and without type 1 diabetes at both levels. The results are robust to selection on ability proxies and across sensitivity analysis. We conclude that the observed pro health-oriented educational choices among people with type 1 diabetes in our data are consistent with disease onset in childhood and adolescence having qualitative impact on life-course choices.

The prevalences of obesity and type 2 diabetes mellitus are dramatically increasing, and there is a strong need for more effective and safer therapies. However, some of drugs show limited efficacy and considerable adverse effects. Furthermore, artificial energy-dense foods and non-caloric foods may promote overeating and weight gain. In this context, a natural food-based approach may represent a valuable means of tackling the obesity-diabetes syndrome. Although recent studies have shown that brown rice improves glucose intolerance and prevents obesity and type 2 diabetes in humans, the underlying molecular mechanisms remain unclear. We found that one of the major components of brown rice, γ-oryzanol (Orz), plays an important role in the metabolically beneficial effects of brown rice. Orz acts as a chemical chaperone and decreases high fat diet (HFD)-induced endoplasmic reticulum (ER) stress in the hypothalamus, thereby leading to a significant shift in preference from fatty to healthy foods. Orz also decreases HFD-induced ER stress in pancreatic β-cells and improves β-cell function. Notably, Orz directly acts on pancreatic islets and enhances glucose-stimulated insulin secretion (GSIS). This evidence highlights food preference as a promising therapeutic target in obesity-diabetes syndrome and suggests that brown rice and Orz may have potential for the treatment of obesity and type 2 diabetes in humans. © 2013 Asian Oceanian Association for the Study of Obesity.

Both fresh and processed foods make up vital parts of the food supply. Processed food contributes to both food security (ensuring that sufficient food is available) and nutrition security (ensuring that food quality meets human nutrient needs). This ASN scientific statement focuses on one aspect of processed foods: their nutritional impacts. Specifically, this scientific statement 1) provides an introduction to how processed foods contribute to the health of populations, 2) analyzes the contribution of processed foods to "nutrients to encourage" and "constituents to limit" in the American diet as recommended by the Dietary Guidelines for Americans, 3) identifies the responsibilities of various stakeholders in improving the American diet, and 4) reviews emerging technologies and the research needed for a better understanding of the role of processed foods in a healthy diet. Analyses of the NHANES 2003-2008 show that processed foods provide both nutrients to encourage and constituents to limit as specified in the 2010 Dietary Guidelines for Americans. Of the nutrients to encourage, processed foods contributed 55% of dietary fiber, 48% of calcium, 43% of potassium, 34% of vitamin D, 64% of iron, 65% of folate, and 46% of vitamin B-12. Of the constituents to limit, processed foods contributed 57% of energy, 52% of saturated fat, 75% of added sugars, and 57% of sodium. Diets are more likely to meet food guidance recommendations if nutrient-dense foods, either processed or not, are selected. Nutrition and food science professionals, the food industry, and other stakeholders can help to improve the diets of Americans by providing a nutritious food supply that is safe, enjoyable, affordable, and sustainable by communicating effectively and accurately with each other and by working together to improve the overall knowledge of consumers. © 2014 American Society for Nutrition.

Adverse reactions to foods are commonly implicated in the causation of ill health. However, foreign antigens, including food proteins and commensal microbes encountered in the gastrointestinal tract, are usually well tolerated. True food allergies, implying immune-mediated adverse responses to food antigens, do exist, however, and are especially common in infants and young children. Allergic reactions to food manifest clinically in a variety of presentations involving the gastrointestinal, cutaneous, and respiratory systems and in generalized reactions such as anaphylaxis. Both IgE-mediated and non-IgE-mediated immune mechanisms are recognized. Important advances in the clinical features underlying specific food hypersensitivity disorders are reviewed.

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.

In this report, we try to approach the question “Is organic food healthier than conventional food?” from a scientific perspective. We can conclude that science does not provide a clear answer to this question. A small number of animal studies and epidemiological studies on health effects from the consumption of organic vs. conventional feed/food have been performed. These studies indicate that the production system of the food has some influence on the immune system of the consuming animal or...

Food engineering is a hybrid of food science and an engineering science, like chemical engineering in my particular case, resulting in the application of chemical engineering principles to food systems and their constituents. With the complexity of food and food processing, one generally narrows his or her interests, and my primary interests were in the kinetics of reactions important in foods, thermal processing, deposition of unwanted materials from food onto heated surfaces (fouling), and microwave heat transfer in baking. This review describes how I developed an interest in these topics and the contributions I have hopefully made to understanding food and to the application of engineering.

The Queensland Government has given its support the establishment of a food irradiation plant in Queensland. The decision to press ahead with a food irradiation plant is astonishing given that there are two independent inquiries being carried out into food irradiation - a Parliamentary Committee inquiry and an inquiry by the Australian Consumers Association, both of which have still to table their Reports. It is fair to assume from the Queensland Government's response to date, therefore, that the Government will proceed with its food irradiation proposals regardless of the outcomes of the various federal inquiries. The reasons for the Australian Democrats' opposition to food irradiation which are also those of concerned citizens are outlined
This popular-level article emphasizes that the ultimate health effects of irradiated food products are unknown. They may include vitamin loss, contamination of food by botulism bacteria, mutations in bacteria, increased production of aflatoxins, changes in food, carcinogenesis from unknown causes, presence of miscellaneous harmful chemicals, and the lack of a way of for a consumer to detect irradiated food. It is claimed that the nuclear industry is applying pressure on the Canadian government to relax labeling requirements on packages of irradiated food in order to find a market for its otherwise unnecessary products
Full Text Available Nowadays, there is an increasing need of new skills for PhD students to face the future labour market prospects. PhD graduates must have qualities attractive not only in academia but also outside, in both manufacture and service-oriented enterprises, in small innovative companies, and in the civil services and public administration, among others. To know what the needs of these future employees are, is of great importance to be able to improve their personal and academic formation. The aim of this work was, in the framework of the EC-funded ISEKI_Food 4 network, to evaluate the most desirable specific and soft skills that PhD students should acquire by the end of their doctoral studies. To this aim, several surveys were conducted and sent to the different stakeholders (academia and food industry partners in order to collect the information needed. Results showed that competences related to research skills and techniques, research management, personal effectiveness and communication skills were considered to be the most valuable skills to be acquired by our PhD students to meet the future needs of the labour market. The importance of these skills was appreciated differently, depending on the stakeholder. To sum up, some recommendations to integrate such valuable skills into the curricula of the PhD student are given.
Food irradiation has been the subject of concern and controversy for many years. The advantages of food irradiation include the reduction or elimination of dangerous bacterial organisms, the control of pests and insects which destroy certain foods, the extension of the shelf-life of many products, for example fruit, and its ability to treat products such as seafood which may be eaten raw. It can also replace existing methods of treatment which are believed to have hazardous side-effects. However, after examining the evidence produced by the proponents of food irradiation, the author questions whether it has any major contribution to make to the problems of foodborne diseases or world food shortages. More acceptable solutions, he suggests, may be found in educating food handlers to ensure that hygienic conditions prevail in the production, storage and serving of food. (author)
Food can be provided with extra beneficial properties by physical processing. These benefits include a reduced possibility of food poisoning, or an increased life of the food. We are familiar with pasteurisation of milk, drying of vegetables, and canning of fruit. These physical processes work because the food absorbs energy during treatment which brings about the changes needed. The energy absorbed in these examples is heat energy. Food irradiation is a less familiar process. It produces similar benefits to other processes and it can sometimes be applied with additional advantages over conventional processing. For example, because irradiation causes little heating, foods may look and taste more natural. Also, treatment can take place with the food in its final plastic wrappers, reducing the risk of re-contamination. (author). 1 ref., 4 figs., 1 tab

The nuclear industry has promoted food irradiation as an effective and safe means of preserving food at minimum risk to the public. However, wide-scale food irradiation programmes such as that approved in the United States of America would have an adverse impact on public health in the following ways: through the consumption of carcinogenic substances generated in irradiated foods, through the use of irradiation to mask bacteriological contamination of spoiled food, through the replacement of fresh foods with nutritionally depleted foods, through accidents with leaks or mishandling of the radiation sources used and through the environmental damage resulting from reactor operation or spent fuel reprocessing necessary to produce the required isotopes for food irradiation. The food irradiation market is potentially enormous, requiring a large number of facilities and isotopes, some, such as caesium-137, would come from the production of nuclear weapons. Evidence of the presence of carcinogenic or mutagenic activity in irradiated foods is discussed. Although the US Federal Drug Administration (FDA) has approved a food irradiation programme it would actually be against the FDA's legal obligation which is to protect the health and safety of the American people.

In this article the author presents the sanitary advantages that are brought by food irradiation. OMS experts state that this technique is safe and harmless for any average global dose between 10 KGy and 100 KGy. Whenever a seminar is held on the topic, it is always concluded that food irradiation should be promoted and favoured. In France food irradiation is authorized for some kinds of products and exceptionally above a 10 KGy dose. Historically food irradiation has been hampered in its development by its classification by American Authorities as food additives in 1958 (Delanay clause). The author draws a parallel between food irradiation and pasteurization or food deep-freezing in their beginnings. (A.C.)

Food irradiation can have a number of beneficial effects, including prevention of sprouting; control of insects, parasites, pathogenic and spoilage bacteria, moulds and yeasts; and sterilization, which enables commodities to be stored for long periods. It is most unlikely that all these potential applications will prove commercially acceptable; the extend to which such acceptance is eventually achieved will be determined by practical and economic considerations. A review of the available scientific literature indicates that food irradiation is a thoroughly tested food technology. Safety studies have so far shown no deleterious effects. Irradiation will help to ensure a safer and more plentiful food supply by extending shelf-life and by inactivating pests and pathogens. As long as requirement for good manufacturing practice are implemented, food irradiation is safe and effective. Possible risks of food irradiation are not basically different from those resulting from misuse of other processing methods, such as canning, freezing and pasteurization. (author)
Food preservation by irradiation is one part of Eisenhower's Atoms for Peace program that is enjoying renewed interest. Classified as a food additive by the Food, Drug, and Cosmetic Act of 1958 instead of a processing technique, irradiation lost public acceptance. Experiments have not been done to prove that there are no health hazards from gamma radiation, but there are new pressures to get Food and Drug Administration approval for testing in order to make commercial use of some radioactive wastes. Irradiation causes chemical reactions and nutritional changes, including the destruction of several vitamins, as well as the production of radiolytic products not normally found in food that could have adverse effects. The author concludes that, lacking epidemiological evidence, willing buyers should be able to purchase irradiated food as long as it is properly labeled
Food irradiation has become a matter of topical interest also in the Federal Republic of Germany following applications for exemptions concerning irradiation tests of spices. After risks to human health by irradiation doses up to a level sufficient for product pasteurization were excluded, irradiation now offers a method suitable primarily for the disinfestation of fruit and decontamination of frozen and dried food. Codex Alimentarius standards which refer also to supervision and dosimetry have been established; they should be adopted as national law. However, in the majority of cases where individual countries including EC member-countries so far permitted food irradiation, these standards were not yet used. Approved irradiation technique for industrial use is available. Several industrial food irradiation plants, partly working also on a contractual basis, are already in operation in various countries. Consumer response still is largely unknown; since irradiated food is labelled, consumption of irradiated food will be decided upon by consumers.

Modern nutritional science is providing ever more information on the functions and mechanisms of specific food components in health promotion and/or disease prevention. In response to demands from increasingly health conscious consumers, the global trend is for food industries to translate nutritional information into consumer reality by developing food products that provide not only superior sensory appeal but also nutritional and health benefits. Today's busy life styles are also driving the development of healthy convenience foods. Recent innovations in food technologies have led to the use of many traditional technologies, such as fermentation, extraction, encapsulation, fat replacement, and enzyme technology, to produce new health food ingredients, reduce or remove undesirable food components, add specific nutrient or functional ingredients, modify food compositions, mask undesirable flavors or stabilize ingredients. Modern biotechnology has even revolutionized the way foods are created. Recent discoveries in gene science are making it possible to manipulate the components in natural foods. In combination with biofermentation, desirable natural compounds can now be produced in large amounts at a low cost and with little environmental impact. Nanotechnology is also beginning to find potential applications in the area of food and agriculture. Although the use of new technologies in the production of health foods is often a cause for concern, the possibility that innovative food technology will allow us to produce a wide variety of food with enhanced flavor and texture, while at the same time conferring multiple health benefits on the consumer, is very exciting.

The business of food retailing and food service is undergoing salient change. The authors argue that the singular force driving this change is the consumer. To understand the linkages in the food marketing channel, this article provides information on the farm-to-retail price spread and the economic forces that influence their magnitude. Examples are given of farm-to-retail price spreads for red meat and dairy industries. In addition, the economics behind the provision of retail services and the growth of the food service industry are discussed. Further, the authors demonstrate that the structure of the food market channel is consumer driven, and present three characteristics of convenience (preparation, delivery, and service) and identify four food distribution channels in terms of convenience (complete convenience, traditional food service, consumer direct, and traditional retail).

Students' attitudes and anxieties about science were measured by responses to two self-report questionnaires. The cohorts were Danish and American students at the upper secondary- and university-levels. Relationships between and among science attitudes, science anxiety, gender, and nationality were examined. Particular attention was paid to constructivist attitudes about science. These fell into at least three broad conceptual categories: Negativity of Science Toward the Individual, Subjective Construction of Knowledge, and Inherent Bias Against Women. Multigroup confirmatory factor analyses revealed that these dimensions of constructivist attitudes were equally applicable and had the same meaning in both cultures. Gender differences in mean levels of constructivist attitudes were found; these varied across the two cultures. Constructivist beliefs were associated with science anxiety, but in different ways for females and males, and for Danes and Americans. In agreement with earlier studies, females in both the US and Danish cohorts were significantly more science anxious than males, and the gender differences for the Americans were larger than those for the Danes. Findings are discussed in terms of their implications for reducing science anxiety by changing constructivist beliefs.
At present, the application of advanced technology during production, processing, storage and distribution of food with an ultimate aim of strengthening the socio-economic status of farmers, entrepreneurs and rural artisan community has paramount importance. The convention made an effort to touch upon the following areas: food and nutritional security and sustainability, food processing and engineering, food safety management systems, food health and nutrition, skill development and entrepreneurship, food science and technology research etc. Papers relevant to INIS are indexed separately

The need to feed nine billion people in 2050 has given rise to widespread debate in science and policy circles. The debate is largely framed in neo-Malthusian terms, and elements of global food security (resilience of the food system, food quantity and quality, right to and access to food) demand
The Federal Food Research Institute does research in the field of nutrition, food and household sciences as well as in related special fields. Among its working priorities are the determination of foreign matter and radionuclides in food as well as food preservation by means of irradiation including dosimetry. The results of those priorities are represented. (orig./MG) [de

This paper reviews researches, commentaries, and conference and public records of food irradiation, published mainly during the period 1987-1989, focusing on the current conditions of food irradiation that may pose not only scientific or technologic problems but also political issues or consumerism. Approximately 50 kinds of food, although not enough to fill economic benefit, are now permitted for food irradiation in the world. Consumerism is pointed out as the major factor that precludes the feasibility of food irradiation in the world. In the United States, irradiation is feasible only for spices. Food irradiation has already been feasible in France, Hollands, Belgium, and the Soviet Union; has under consideration in the Great Britain, and has been rejected in the West Germany. Although the feasibility of food irradiation is projected to increase gradually in the future, commercial success or failure depends on the final selection of consumers. In this respect, the role of education and public information are stressed. Meat radicidation and recent progress in the method for detecting irradiated food are referred to. (N.K.) 128 refs

An overall perspective on trends in food consumption is presented. Nutrition awareness is at an all-time high; consumption is influenced by changes in disposable income, availability of convenience foods, smaller household size, and an increasing proportion of ethnic minorities in the population.

A worldwide standard on food irradiation was adopted in 1983 by codex Alimentarius Commission of the Joint Food Standard Programme of the Food and Agriculture Organization (FAO) of the United Nations and The World Health Organization (WHO). As a result, 41 countries have approved the use of irradiation for treating one or more food items and the number is increasing. Generally, irradiation is used to: food loses, food spoilage, disinfestation, safety and hygiene. The number of countries which use irradiation for processing food for commercial purposes has been increasing steadily from 19 in 1987 to 33 today. In the frames of the national programme on the application of irradiation for food preservation and hygienization an experimental plant for electron beam processing has been established in Inst. of Nuclear Chemistry and Technology. The plant is equipped with a small research accelerator Pilot (19 MeV, 1 kW) and industrial unit Electronika (10 MeV, 10 kW). On the basis of the research there were performed at different scientific institutions in Poland, health authorities have issued permissions for irradiation for; spices, garlic, onions, mushrooms, potatoes, dry mushrooms and vegetables.

Full Text Available Disordered eating behaviors are implicated in the development and persistence of obesity in childhood, adolescence, and adulthood. The purpose of this study was to provide a qualitative perspective of obese youth’s eating behaviors through the lens of their parent as they attempt to create healthy changes. An in-depth secondary analysis was conducted for the construct of food intimacy that evolved as part of a larger study investigating how parents promote health for their obese child. Seventeen parents of 10- to 14-year-old obese youth were interviewed. Themes and concepts were developed using grounded theory. Parents described child behaviors such as losing control and sneaky eating to obtain food, as well as using food for comfort, pleasure, and simply loving food. The relationship between these children and food was identified as the over-arching theme, food intimacy. This study highlights the intimate relationship these children developed with food and the powerful influence of this relationship on their eating behaviors. This suggests that prescribed interventions such as exercising more and eating less may be ineffective in certain obese children, and that more focus should be placed on investigating the relationship an obese child has with food.
Processing of food with low levels of radiation has the potential to contribute to reducing both spoilage of food during storage - a particular problem in developing countries - and the high incidence of food-borne disease currently seen in all countries. Approval has been granted for the treatment of more than 30 products with radiation in over 30 countries but, in general, governments have been slow to authorize the use of this new technique. One reason for this slowness is a lack of understanding of what food irradiation entails. This book aims to increase understanding by providing information on the process of food irradiation in simple, non-technical language. It describes the effects that irradiation has on food, and the plant and equipment that are necessary to carry it out safely. The legislation and control mechanisms required to ensure the safety of food irradiation facilities are also discussed. Education is seen as the key to gaining the confidence of the consumers in the safety of irradiated food, and to promoting understanding of the benefits that irradiation can provide. (orig.)

Definition and significance of food irradiation were described. The details of its development and present state were also described. The effect of the irradiation on Irish potatoes, onions, wiener sausages, kamaboko (boiled fish-paste), and mandarin oranges was evaluated; and healthiness of food irradiation was discussed. Studies of the irradiation equipment for Irish potatoes in a large-sized container, and the silo-typed irradiation equipment for rice and wheat were mentioned. Shihoro RI center in Hokkaido which was put to practical use for the irradiation of Irish potatoes was introduced. The state of permission of food irradiation in foreign countries in 1975 was introduced. As a view of the food irradiation in the future, its utilization for the prevention of epidemics due to imported foods was mentioned. (Serizawa, K.)

Since the term first appeared, food porn has typically referred to watching others cook on television or gazing at unattainable dishes in glossy magazines without actually cooking oneself. This forum seeks to revisit this notion of food porn that is mostly taken for granted in both popular and scholarly literature. It offers a brief perspective of the appearance and use of the term food porn to examine how it came to be a term used mostly by commentators rather than by people actively engaged in the world of cooking. Practitioners (chefs and a food television producer) and academics address whether or not food porn exists, what shape it might take, what purpose it might serve, and/or what usefulness it might have, showing that these contentious issues are more complex than the ease with which the term is used might let on.

Data science has attracted a lot of attention, promising to turn vast amounts of data into useful predictions and insights. In this article, we ask why scientists should care about data science. To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

Most countries have expended much effort to develop food safety control systems to ensure safe food supplies within their borders. China, as one of the world's largest food producers and consumers,pays a lot of attention to food safety issues. In recent years, China has taken actions and implemented a series of plans in respect to food safety. Food safety control systems including regulatory, supervisory,and science and technology systems, have begun to be established in China. Using, as a base, an analysis of the current Chinese food safety control system as measured against international standards, this paper discusses the need for China to standardize its food safety control system. We then suggest some policies and measures to improve the Chinese food safety control system.

From ancient wisdom to modern science and technology, Chinese cuisine has been established from a long history of the country and gained a global reputation of its sophistication. Traditional Chinese foods and cuisine that exhibit Chinese culture, art and reality play an essential role in Chinese people's everyday lives. Recently, traditional Chinese foods have drawn a great degree of attention from food scientists and technologists, the food industry, and health promotion institutions worldwide due to the extensive values they offer beyond being merely another ethnic food. These traditional foods comprise a wide variety of products, such as pickled vegetables, salted fish and jellyfish, tofu and tofu derived products, rice and rice snack foods, fermented sauces, fish balls and thousand-year-old eggs. An overview of selected popular traditional Chinese foods and their processing techniques are included in this paper. Further development of the traditional techniques for formulation and production of these foods is expected to produce economic, social and health benefits.

The discovery of plant polyphenols in food is perhaps one of the biggest breakthroughs in modern food science. Plant polyphenols are known for their role in food quality and safety, since they contribute significantly to taste, flavour, colour, stability etc., while they are increasingly recognised as important factors in long-term health, contributing towards reducing the risk of chronic disease. Almost 200years ago, hydrolyzable tannins (HTs) were the first group of plant polyphenols subjected to analytical chemical research. Despite the lack of commercially available standards, food analysis research offers a wealth of papers dealing with extraction optimisation, identification and quantification of HTs. The object of this review is to summarise analytical chemistry applications and the tools currently used for the analysis of HTs in food. Copyright © 2012 Elsevier Ltd. All rights reserved.

Review of some of the unique food microbiology problems and problem-generating circumstances the Skylab manned space flight program involves. The situations these problems arise from include: extended storage times, variations in storage temperatures, no opportunity to resupply or change foods after launch of the Skylab Workshop, first use of frozen foods in space, first use of a food-warming device in weightlessness, relatively small size of production lots requiring statistically valid sampling plans, and use of food as an accurately controlled part in a set of sophisticated life science experiments. Consideration of all of these situations produced the need for definite microbiological tests and test limits. These tests are described along with the rationale for their selection. Reported test results show good compliance with the test limits.

By using the ILSI network in Asia, we are holding a session focused on food safety programs in several Asian areas. In view of the external environment, it is expected to impact the global food system in the near future, including the rapid increase in food demand and in public health services due to population growth, as well as the threats to biosecurity and food safety due to the rapid globalization of the food trade. Facilitating effective information sharing holds promise for the activation of the food industry. At this session, Prof. Hwang shares the current situation of Food Safety and Sanitation Regulations in Taiwan. Dr. Liu provides a talk on the role of risk assessment in food regulatory control focused on aluminum-containing food additives in China. After the JECFA evaluation of aluminum-containing food additives in 2011, each country has carried out risk assessment based on dietary intake surveys. Ms. Chan reports on the activities of a working group on Food Standards Harmonization in ASEAN. She also explains that the ILSI Southeast Asia Region has actively supported the various ASEAN Working Groups in utilizing science to harmonize food standards. Prof. Park provides current research activities in Korea focused on the effect of climate change on food safety. Climate change is generally seen as having a negative impact on food security, particularly in developing countries. We use these four presentations as a springboard to vigorous discussion on issues related to Food Safety in Asia.

Full Text Available The modem network and digitalized society is full of social changes in various accustomed spheres of our lives including transformation in food practices. The author gives an example of the easiest way how to book food virtually and get it home this day according to tastes of a customer. Moreover the article represents new forms of specific societies existed in the Internet called food-blogs. This, on the author's mind, changes the traditional mechanism of people's choice. Food-blogs are analyzed through the prism of multifunctionalism and dynamics of food and trust. When the process of food preparing and eating attains new communicative functions. Moreover the author notes some social reasons why one user choses this or that food-blog. For instance, the popularity of blogger and network users trust, mostly «blinded». Beside the point, the conception of «trust» used in the text is based on science works of contemporary sociologist P. Sztompka. Both socialized and communicative functions of food are described through theories of R. Bart and G. Simmel. It is underlined in the text that food transforms and gains new qualities notin traditional ways we used to think but in social and cultural construction in virtual space and through network communication.

The importance and prospects for MRI as applied to intact plants and to foods are presented in view of one of humanity's most pressing concerns, the sustainable and healthy feeding of a worldwide increasing population. Intact plants and foods have in common that their functionality is determined by complex multiple length scale architectures. Intact plants have an additional level of complexity since they are living systems which critically depend on transport and signalling processes between and within tissues and organs. The combination of recent cutting-edge technical advances and integration of MRI accessible parameters has the perspective to contribute to breakthroughs in understanding complex regulatory plant performance mechanisms. In food science and technology MRI allows for quantitative multi-length scale structural assessment of food systems, non-invasive monitoring of heat and mass transport during shelf-life and processing, and for a unique view on food properties under shear. These MRI applications are powerful enablers of rationally (re)designed food formulations and processes. Limitations and bottlenecks of the present plant and food MRI methods are mainly related to short T2 values and susceptibility artefacts originating from small air spaces in tissues/materials. We envisage cross-fertilisation of solutions to overcome these hurdles in MRI applications in plants and foods. For both application areas we witness a development where MRI is moving from highly specialised equipment to mobile and downscaled versions to be used by a broad user base in the field, greenhouse, food laboratory or factory.

Various aspects of food treatment by cobalt 60 or caesium 137 gamma radiation are reviewed. One of the main applications of irradiation on foodstuffs lies in its ability to kill micro-organisms, lethal doses being all the lower as the organism concerned is more complex. The effect on parasites is also spectacular. Doses of 200 to 300 krad are recommended to destroy all parasites with no survival period and no resistance phenomenon has ever been observed. The action of gamma radiation on macromolecules was also investigated, the bactericide treatment giving rise to side effects by transformation of food components. Three examples were studied: starch, nucleic acids and a whole food, the egg. The organoleptic aspect of irradiation was examined for different treated foods, then the physical transformations of unpasteurized, heat-pasteurized and radio-pasteurized eggs were compared. The report ends with a brief analysis of the toxicity and conditions of application of the treatment.

Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people-environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food.

How is science represented by the media? Who defines what counts as a risk, threat or hazard, and why? In what ways do media images of science shape public perceptions? What can cultural and media studies tell us about current scientific controversies? "Media, Risk and Science" is an exciting exploration into an array of important issues, providing a much needed framework for understanding key debates on how the media represent science and risk. In a highly effective way, Stuart Allan weaves together insights from multiple strands of research across diverse disciplines. Among the themes he examines are: the role of science in science fiction, such as "Star Trek"; the problem of 'pseudo-science' in "The X-Files"; and how science is displayed in science museums. Science journalism receives particular attention, with the processes by which science is made 'newsworthy' unravelled for careful scrutiny. The book also includes individual chapters devoted to how the media portray environmental risks, HIV-AIDS, food s...

The use of ionising radiation for food preservation is a much-disputed topic, both among experts and among consumers. Pros and cons of this issue were discussed in detail at the consumers' forum. Professor Dr. Johannes Friedrich Diehl, Director of the Institute for Biochemistry of the Food Research Centre, Karlsruhe, is a well-known supporter of the new method of food preservation; he sees advantages in the radiopreservation of food because, for example, losses due to inedibility are reduced, the danger of salmonellosis is decreased, just as the use of chemicals. He thinks this method to be without danger to health, shown by many years of experience. Opponents to food irradiation like Prof. Dr. Konrad Pfeilsticker, Professor for food science and food chemistry at the Bonn University deem the method to be unnecessary and raise the problem of qualitative changes caused in the food. In the course of the discussions, the pros and cons seemed to balance each other out. (orig./AJ) [de

Global societies are becoming increasingly urban. This shift toward urban living is changing our relationship with food, including how we shop and what we buy, as well as ideas about sanitation and freshness. Achieving food security in an era of rapid urbanization will require considerably more understanding about how urban and food systems are intertwined. Here we discuss some potential understudied linkages that are ripe for further examination. Copyright © 2016, American Association for the Advancement of Science.
Food treatment by means of ionizing energy, or irradiation, is an innovative method for its preservation. In order to treat important volumes of food, it is necessary to have industrial irradiation installations. The effect of radiations on food is analyzed in the present special work and a calculus scheme for an Irradiation Plant is proposed, discussing different aspects related to its project and design: ionizing radiation sources, adequate civil work, security and auxiliary systems to the installations, dosimetric methods and financing evaluation methods of the project. Finally, the conceptual design and calculus of an irradiation industrial plant of tubercles is made, based on the actual needs of a specific agricultural zone of our country. (Author) [es

Radionuclides in the Food Chain reviews past experience in meeting the challenge of radionuclide contamination of foodstuffs and water sources and, in the wake of the reactor accidents at Chernobyl and Three Mile Island, presents current concepts and programs relating to measurement, surveillance, effects, risk management, evaluation guidelines, and control and regulatory activities. This volume, based on a symposium sponsored by the International Life Sciences Institute in association with the International Institute for Applied Systems Analysis, which brought together both radiation experts and food industry policymakers, examines such vital topics as structural problems in large-scale crisis-managment systems; dose assessment from man-made sources; international recommendations on radiation protection; airborne contamination, as well as aquatic and soilborne radionuclides; food-chain contamination from testing nuclear devices; long-term health effects of radionuclides in food and water supplies; and use of mathematical models in risk assessment and management.

Food scientists are routinely confronted with the need to measure physical properties related to sensory texture and processing needs. These properties are determined by rheological methods, where rheology is a science devoted to the deformation and flow of all materials. Rheological properties should be considered a subset of the textural properties of foods, because the sensory detection of texture encompasses factors beyond rheological properties. Specifically, rheological methods accurately measure "force," "deformation," and "flow," and food scientists and engineers must determine how best to apply this information. For example, the flow of salad dressing from a bottle, the snapping of a candy bar, or the pumping of cream through a homogenizer are each related to the rheological properties of these materials. In this chapter, we describe fundamental concepts pertinent to the understanding of the subject and discuss typical examples of rheological tests for common foods. A glossary is included as Sect. 30.6 to clarify and summarize rheological definitions throughout the chapter.

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
In Japan, the first food irradiation research was carried out on the preservation of fish and fishery products. In 1966, the Atomic Energy Commission of the Japanese Government (JAEC) decided to promote the National Project on Food Irradiation and, in 1967, the Steering Committee on food irradiation research in the Atomic Energy Bureau, Science and Technology Agency, selected the following food items as of economic importance to the country, i.e., potatoes, onions, rice, wheat, ''Vienna'' sausage, ''kamaboko'' (fish meat jelly products) and mandarin oranges. The National Project is expected to finish at the end of the 1981 fiscal year. Based on the studies by the National Project, irradiated potatoes were given ''unconditional acceptance'' for human consumption in 1972. Already in 1973, a commercial potato irradiator was built at Shihoro, Hokkaido. In 1980, the Steering Committee submitted a final report on the effectiveness and wholesomeness studies on irradiated onions to the JAEC. This paper gives a brief explanation of the legal aspects of food irradiation in Japan, and the present status of wholesomeness studies on the seven items of irradiated foods. In addition, topics concerning food irradiation research on ''kamaboko'', especially on the effectiveness and a new detecting method for the irradiation treatment of these products, are outlined.

Full Text Available ABSTRACT This narrative literature review aimed to analyze the results of studies on the food intake of university students. A literature search was conducted in July 2014 and updated in July 2016 in the Scopus, MedLine/PubMed, and SciELO databases, using descriptors related to university students and food intake in English and Portuguese. Overall, 37 studies that analyzed university students’ food intake were included in this review, eight of which were conducted in Brazil. The results demonstrated that most university students have unhealthy eating behaviors, such as high intake of fast foods, snacks, sweets, soft drinks, and alcoholic beverages, and low intake of fruits, vegetables, fish, whole grains, and legumes. Undergraduate students of health sciences, such as nursing, nutrition, and medicine, did not have healthier diets. University students’ food intake was characterized as unhealthy, regardless of undergraduate program or sex, especially among students who left the parents’ home and became responsible for their own food. Therefore, there is a need of developing public policies that promote healthy eating habits among students, such as interventions to change their eating habits and increase their access to healthy foods at the university environment.

Food systems are rapidly changing as world population grows, increasing urbanization occurs, consumer tastes and preferences change and differ in various countries and cultures, large scale food production increases, and food imports and exports grow in volume and value. Consumers in all countries have become more insistent that foods available in the marketplace are of good quality and safe, and do not pose risks to them and their families. Publicity about food risk problems and related risks, including chemical and microbiological contamination of foods, mad-cow disease, avian flu, industrial chemical contamination all have made consumers and policy makers more aware of the need of the control of food safety risk factors in all countries. To discuss changes in food systems, and in consumer expectations, that have placed additional stress on the need for better control of food safety risks. Food producers, processors, and marketers have additional food law and regulations to meet; government agencies must increase monitoring and enforcement of adequate food quality and safety legislation and coordinate efforts between agriculture, health, trade, justice and customs agencies; and academia must take action to strengthen the education of competent food legislation administrators, inspectorate, and laboratory personnel for work in government and industry, including related food and food safety research . Both Government and the food industry must assure that adequate control programs are in place to control the quality and safety of all foods, raw or processed, throughout the food chain from production to final consumption. This includes appropriate laboratory facilities to perform necessary analysis of foods for risk and quality factors, and to carry out a wide range of food science, toxicological and related research.
The Department of Energy has historically sponsored a range of university-level science education activities including summer and semester-length research appointments at DOE National Laboratories for university faculty, undergraduate and graduate students. The Department's involvement in precollege science education has significantly expanded over the past year. This talk will summarize the status of the Department's plans for university and precollege science education initiatives developed at the Berkeley Math/Science Education Action Conference held last October at the Lawrence Hall of Science and co-chaired by Dr. Glenn Seaborg and the Secretary of Energy, Admiral James Watkins

Identifying fundamental drivers of science and developing predictive models to capture its evolution are instrumental for the design of policies that can improve the scientific enterprise-for example, through enhanced career paths for scientists, better performance evaluation for organizations hosting research, discovery of novel effective funding vehicles, and even identification of promising regions along the scientific frontier. The science of science uses large-scale data on the production of science to search for universal and domain-specific patterns. Here, we review recent developments in this transdisciplinary field.

Threshold doses or Estimated Eliciting Doses (EEDs) represent an important new field of research in food allergy. Clinicians and regulators have embraced some toxicological concepts such as LOAEL and NOAEL and applied them to an area of significant clinical uncertainty and interest. The impact of intrinsic human factors (e.g., asthma and exercise) and extrinsic event factors (e.g., season, location and especially dose of allergen) on a future allergic reaction in the community needs to be considered carefully when interpreting results of clinical and research low-dose food challenges. The ongoing cooperation of food allergy research groups in medicine, food science and government will surely deliver results of the highest importance to the wider communities of allergology, food science and technology and the increasing number of allergic consumers
Radurisation can give a new lease of shelf life to food and cut down contamination, but it is bound to cause problems - even among comparatively tame South African consumers. In this article the facts about radurization are discussed: the labelling of irradiated products, the problem of making a bad product good by using irradiation, consumer pressure, attitudes, fears and resistance. The economics of radurised foodstuffs are also discussed

that the medfly attacking citrus, the olive fly, the codling moth attacking apples, the tsetse fly and a number of other insects can be eliminated in this way. Radiation can be used to attenuate parasitic larvae attacking animals. The parasites which have thus lost their virulence are used in the production of animal vaccines. In fact, this is still the only known method of producing such vaccines. Isotopic tracers are used to study the movement and metabolism of nutrients in animal production and are particularly useful in studies of essential micronutrients. This unique ability of isotopic tracers to enable detection of chemicals in minute quantities forms the basis for a new program on studies of harmful pesticide residues on plant and animal foods. The sterilizing and killing effect of radiation has been shown to be uniquely effective in preventing or delaying spoilage in a variety of food commodities. Radiation preservation can, for example, be applied to perishable products which do not tolerate cooking or freezing - even after the products are packed. To foster international activities in the field of nuclear science in food and agriculture, the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture carries out a single joint program of work approved by the two parent organizations. To carry out work in all these fields, the Division relies heavily on the concept of coordinated research based on research contracts or research agreements. A large part of the work is carried out under various technical assistance projects including expert advice, equipment and training and through the two UNDP Special Fund Projects executed by the IAEA. The IAEA Laboratory plays an indispensable role in the Division’s programs by providing various coordinating services, research, and specialized training.

Gastroesophageal reflux disease is a chronic condition with a high prevalence in western countries. Transient lower esophageal sphincter relaxation episodes and a decreased lower esophageal sphincter pressure are the main mechanisms involved. Currently used drugs are efficient on reflux symptoms, but only as long as they are administered, because they do not modify the reflux barrier. Certain nutrients or foods are generally considered to increase the frequency of gastroesophageal reflux symptoms, therefore physicians recommend changes in diet and some patients avoid bothering foods. This review summarizes current knowledge regarding food and gastroesophageal reflux. For example, fat intake increases the perception of reflux symptoms. Regular coffee and chocolate induce gastroesophageal reflux and increase the lower esophageal exposure to acid. Spicy foods might induce heartburn, but the exact mechanism is not known. Beer and wine induce gastroesophageal reflux, mainly in the first hour after intake. For other foods, like fried food or carbonated beverages data on gastroesophageal reflux is scarce. Similarly, there is few data about the type of diet and gastroesophageal reflux. Mediterranean diet and a very low carbohydrate diet protect against reflux. Regarding diet-related practices, consistent data showed that a "short-meal-to-sleep interval" favors reflux episodes, therefore some authors recommend that dinner should be at least four hours before bedtime. All these recommendations should consider patient's weight, because several meta-analysis showed a positive association between increased body mass index and gastroesophageal reflux disease.

Advanced food technologies fused with radiation technology could be applied to the development of various special-purpose foods such space foods, combat rations, emergency foods, and sterile patient meals. In U.S.A, the National Aeronautics and Space Administration and the U.S. Army Natick Soldier RD and E Center co-developed the hazard analysis of critical control point, which is a essential hygienic control system in food industry. Moreover, strict manufacturing standards to produce shelf-stable foods using radiation (ionizing energy) technology were established. In Korea, the advanced food technologies to sterilize various foods using irradiation technology were expected to be applied as a hygiene process on group meals and ready-to-eat/ready-to cook foods, and to produce foods for patients with high hygienic, nutritional, and organoleptic qualities through the combination treatments with irradiation technology. And, it was considered that the advanced technology would improve the related industries and national economy by introducing the food irradiation technology to the Korean traditional fermented foods to improve their functionality. In conclusion, the advanced food technologies which are preoccupied by some developed countries like U.S.A. and Russia will make a contribution to the development of national science and technology, and competitiveness promotion of industry.

The job of CERN Director-General comes with a lot of responsibility, and that’s particularly true today. We’re living through a period of unique circumstances for science. Positive indicators, such as a renewal of interest in physical sciences at the University level and unprecedented public interest in the LHC, are aligning with storm clouds in the form of a prolonged economic crisis that will put downward pressure on everyone’s budgets. That means that science has to make its voice heard if it’s to preserve support, and if it wants to be in a position to play the role it must in navigating the major societal challenges of our time. For that reason, I have been a fairly rare sight at CERN of late. Last week, I was in Davos for the annual meeting of the World Economic Forum. It was my second time at Davos, and I used the opportunity to argue that science should be more closely linked to the political thread of the meeting. I think my argument was he...

The role of the food industry (retailers, manufacturers and food service) in helping consumers eat healthily and sustainably has been receiving considerable attention in recent years. This paper focuses on the challenges facing the food industry and the role of food reformulation in meeting these challenges, through the lens of a public health nutritionist. Attention has been heightened by the Government's Responsibility Deal, launched in early 2011 by the Department of Health (England), by the UK's engagement with the global food security and food supply sustainability agendas and by the Government Office of Science's Foresight report. The Responsibility Deal's food network has to date focused on reduction of trans fatty acids, salt and calories and out-of-home calorie labelling (in food service settings). New pledges are expected soon on increasing fruit and vegetable intakes. Reformulation is a major feature of the Responsibility Deal's approach, and along with other approaches such as portion control, choice editing and information provision, there is potential to increase the breadth of healthier choices available to the public. With the exception of fruit and vegetables, the emphasis has been almost exclusively on aspects of the diet that are in excess for many of the population (e.g. energy and salt). Evidence of low consumption of some key micronutrients by some groups of the population, particularly adolescents and young adults, often alongside excess energy intake compared with expenditure, is all too often overlooked. This paper summarises the progress made to date, the challenges faced and the opportunities that exist, with particular focus on reformulation. One of the biggest challenges is the relatively poor understanding of how to effect positive and long-term dietary behaviour change. The paper concludes that, in isolation, reformulation is unlikely to provide a complete solution to the challenge of improving eating patterns and nutrient provision

Investigations into the potential of food irradiation as a major food processing technology have been underway for over twenty years. Considerable progress has been made in the areas of its science and technology, its governmental and international regulation, its acceptance by consumers, and its economic impact on the cost of food. The paper reviews some of the major steps taken in food irradiation and predicts that it will become a new world wide application of technology in the 1980's

This paper presents a theoretical framework for researching children and food consumption in the family. The proposed framework draws on contemporary social science approaches to the study of family decision making, food consumption patterns and routines, and consumer competence and food......-related lifestyle in order to understand children and families through their everyday practices. It suggest a new emphasis on children as active agents in the formation of family food consumption patterns and looks at children's food choices as embedded in everyday family life. We focus especially on the construct...... of the "Consumer Competence" of the child as one important aspect determining the way a child is involved in and gains influence over family food consumption. The paper also demonstrates how a mixed methods design, employing ethnographic and survey techniques, involves advances in methodological and analytical...

Finnish students (N=3261) filled out a questionnaire on attitudes towards genetically modified and organic food, plus the rational-experiential inventory, the magical thinking about food and health scale, Schwartz's value survey and the behavioural inhibition scale. In addition, they reported their eating of meat. Structural equation modelling of these measures had greater explanatory power for attitudes towards genetically modified (GM) foods than for attitudes towards organic foods (OF). GM attitudes were best predicted by natural science education and magical food and health beliefs, which mediated the influence of thinking styles. Positive attitudes towards organic food, on the other hand, were more directly related to such individual differences as thinking styles and set of values. The results of the study indicate that OF attitudes are rooted in more fundamental personal attributes than GM attitudes, which are embedded in a more complex but also in a more modifiable network of characteristics.

All foods are functional at some physiological level, but it is the position of the American Dietetic Association (ADA) that functional foods that include whole foods and fortified, enriched, or enhanced foods have a potentially beneficial effect on health when consumed as part of a varied diet on a regular basis, at effective levels. ADA supports research to further define the health benefits and risks of individual functional foods and their physiologically active components. Health claims on food products, including functional foods, should be based on the significant scientific agreement standard of evidence and ADA supports label claims based on such strong scientific substantiation. Food and nutrition professionals will continue to work with the food industry, allied health professionals, the government, the scientific community, and the media to ensure that the public has accurate information regarding functional foods and thus should continue to educate themselves on this emerging area of food and nutrition science. Knowledge of the role of physiologically active food components, from plant, animal, and microbial food sources, has changed the role of diet in health. Functional foods have evolved as food and nutrition science has advanced beyond the treatment of deficiency syndromes to reduction of disease risk and health promotion. This position paper reviews the definition of functional foods, their regulation, and the scientific evidence supporting this evolving area of food and nutrition. Foods can no longer be evaluated only in terms of macronutrient and micronutrient content alone. Analyzing the content of other physiologically active components and evaluating their role in health promotion will be necessary. The availability of health-promoting functional foods in the US diet has the potential to help ensure a healthier population. However, each functional food should be evaluated on the basis of scientific evidence to ensure appropriate integration

In view on the enormous health and economic consequences of foodborne diseases, irradiation decontamination and disinfestation of pathogen-containing foods must be considered one of the most significant recent contributions to public health made by food science and technology. Food irradiation has an important part to play with in the promotion of food safety and in the reduction of food losses. The unwarranted rejection of the process, often based on a lack of understanding of what food irradiation entails, may hamper its use in most countries that could benefit most

Food commodities are packaged and hygienically transported to protect and preserve them from any un-acceptable alteration in quality, before reaching the end-consumer. Food packaging continues to evolve along-with the innovations in material science and technology, as well as in light of consumer's demand. Presently, the modern consumers of competitive economies demands for food with natural quality, assured safety, minimal processing, extended shelf-life and ready-to-eat concept. Innovative packaging systems, not only ascertains transit preservation and effective distribution, but also facilitates communication at the consumer levels. The technological advances in the domain of food packaging in twenty-first century are mainly chaired by nanotechnology, the science of nano-materials. Nanotechnology manipulates and creates nanometer scale materials, of commercial and scientific relevance. Introduction of nanotechnology in food packaging sector has significantly addressed the food quality, safety and stability concerns. Besides, nanotechnology based packaging intimate's consumers about the real time quality of food product. Additionally, nanotechnology has been explored for controlled release of preservatives/antimicrobials, extending the product shelf life within the package. The promising reports for nanotechnology interventions in food packaging have established this as an independent priority research area. Nanoparticles based food packages offer improved barrier and mechanical properties, along with food preservation and have gained welcoming response from market and end users. In contrary, recent advances and up-liftment in this area have raised various ethical, environmental and safety concerns. Policies and regulation regarding nanoparticles incorporation in food packaging are being reviewed.

The International Atomic Energy Agency (IAEA) and Food and Agriculture Organization of the United Nations (FAO) have been partners for nearly half a century, contributing to efforts toward shared goals of food security. Their mission - through a Joint Division headquartered at the IAEA in Austria - is to help countries effectively use nuclear science and related technologies for food and agricultural development. Millions of people today look to a better future because of the foresight and longstanding investment of FAO and IAEA Member States in the 'Atoms for Food' partnership. Worldwide, more than 100 countries are working together through the Joint Division to increase their harvests, combat animal and plant diseases and pests, and protect the lands, water resources, and environments on which food and agricultural production depend. This century's stark realities of hunger, poverty, climate change, and environmental degradation bring an unprecedented scale of challenges to the fields of food and agriculture. Action requires the research, expertise, and experience of the FAO/IAEA partnership and other effective alliances worldwide to help countries achieve and sustain higher levels of food security for their people. The two organizations are well matched. FAO brings to the table its comprehensive knowledge and networks on food and agriculture. The IAEA, in turn, contributes technical know-how, specifically in agricultural and related applications of nuclear science and technology. The partnership's potential builds on decades of experience
