    Full Text Available The paper deals with the marketability of packaged fruit and vegetables, as a new trend of satisfying consumer needs, in connection with selling-culture of stall selling and self-stores sales. It emphasize fact that food have to be wrapped into the quality, health packages, under the conditions of the Act. 477/2001 Coll.Specific data for the analytical part of this paper was provided by Hortim International Ltd. This company has operate on the Czech market since 1995. Analysis of the economic results confirmes the legitimacy of the sale of packaged fresh fruits and vegetables, but there will be neccesary longer lasting promotion. This fact also confirmed the research of consumer demand, that was made by authors. Determinant for the success sales are these factors: consumer confidence that the packaged products of fruit and vegetables are high quality.

    Physical access to stores selling groceries, fresh fruit and vegetables (FV) is essential for urban dwellers. In Canadian cities where low-density development practices are common, social and material deprivation may be compounded by poor geographic access to healthy food. This case study examines access to food stores selling fresh FV in Gatineau, Quebec, to identify areas where poor access is coincident with high deprivation. Food retailers were identified using two secondary sources and each store was visited to establish the total surface area devoted to the sale of fresh FV. Four population-weighted accessibility measures were then calculated for each dissemination area (DA) using road network distances. A deprivation index was created using variables from the 2006 Statistics Canada census, also at the scale of the DA. Finally, six classes of accessibility to a healthy diet were constructed using a k-means classification procedure. These were mapped and superimposed over high deprivation areas. Overall, deprivation is positively correlated with better accessibility. However, more than 18,000 residents (7.5% of the population) live in high deprivation areas characterized by large distances to the nearest retail food store (means of 1.4 km or greater) and virtually no access to fresh FV within walking distance (radius of 1 km). In this research, we identified areas where poor geographic access may introduce an additional constraint for residents already dealing with the challenges of limited financial and social resources. Our results may help guide local food security policies and initiatives.

    The freshness of citrus fruits commonly available in the market was non-destructively assessed by Raman spectroscopy. Intact clementine, mandarin and tangerine species were characterised concerning their carotenoids skin Raman signalling in a time course from the moment they were acquired as fresh stock, supplying the market, to the physical degradation, when they were no longer attractive to consumers. The freshness was found to strongly correlate to the peel Raman signal collected from the same area of the intact fruits in a time course of a maximum of 20days. We have shown that the intensity of the carotenoid Raman signal is indeed a good indicator of fruit freshness and introduced a Raman coefficient of freshness (C Fresh ), whose time course is linearly decreasing, with different slope for different citrus groups. Additionally, we demonstrated that the freshness assessment could be achieved using a portable Raman instrument. The results could have a strong impact for consumer satisfaction and the food industry. Copyright © 2017 Elsevier Ltd. All rights reserved.

    To compare the types and quantities of carbohydrate, electrolytes, pH and osmolarity of fresh fruit juices and commercial fruit juices. Forty kinds of fresh fruits available in Thai markets were analyzed for types and quantities of carbohydrate, electrolyte, pH and osmolarity and compared with previously obtained data for commercial fruit juices. Most fresh fruit juices did not contain sucrose, whereas, commercial fruit juices mostly have sucrose in the range of 3-112 g/L. Although both fruit juices were acidic (pH varied from 3.6-6.7 and 3.2-5.8 of fresh juice and commercial juice), fresh fruit juices had a more neutral pH than commercial fruit juices. Apple, guava, orange, pear, and pineapple juices from commercial fruit juices had a high osmolarity compared with fresh fruit juices. All types of fresh fruit juices contained less sodium than commercial ones, whereas, most fresh fruit juices contained more potassium, phosphorus, and magnesium than commercial fluids. The nutrient content of fresh fruit juices and commercial fruit juices from the same kinds of fruits are not the same, possibly due to the manufacturing process. Therefore, physicians should know the composition of fruit juices in order to advise patients properly.

    2000-01-01

    There are presented the results of tests concerning the effects of accelerated electron-beam to some early fresh fruits like strawberries, cherries, sour-cherries and apples. The irradiation were performed on common varieties, in normal conditions, to the NILPRP-Electron Accelerator Laboratory facility consisting in electron-beam accelerators which have the following parameters: - mean beam current, 5 μA; - electron mean energy approximately, 7 MeV; - pulse period, 3.5 μs. The doses varied between 0.5-3.0 kGy and the dose rate was about 1500 Gy/min. It was determined the fruit shelf life and there were analysed the main organoleptic and nutritional properties, as: size, shape, colour, dry weight, acidity, total and reducing sugars, ascorbic acid content and other. For the electron-beam treated fruits it was pointed out an increase in freshness and shelf life extension by 5-7 days for strawberries and more than two weeks for cherries. Otherwise, for the applied doses, the electron-beam irradiation did not produce any significant changes in the fruit characteristic values. These results lead to the conclusion that the electron accelerators could be successfully used as a technological solution for the fresh fruits processing, in view of shelf life extension. There are presented also some technical and economical considerations on the feasibility of this technology and on the use of electron-beam machines for food irradiation. (authors)

    The use of ionizing radiation in preservation of fruits and vegetables is widely recognized. In this paper it is presented a study of the effect of electron-beam irradiation of some fresh, early and perishable fruits, like strawberries, cherries, and sour cherries concerning their shelf-life time extension. The irradiations were performed on common varieties in normal conditions to the IPTRD's electron-beam accelerator (Bucharest-Magurele) having the following parameters: flow current 10 μA, power 60 W and electron mean energy 6.23 MeV. The irradiation doses varied between 0.5-3.0 kGy and the dose rates between 100-1500 Gy/min. It was observed the fruit preservation capability of the treatment and it was analysed the main characteristics as organoleptic properties, weight of dry component, acidity, total and reducing sugars, ascorbic acid content and others. It was evidenced an increase in freshness and shelf-life extension by 5-7 days for strawberries and up to two weeks for cherries without any significant changes in the values of the considered parameters. Otherwise, for the applied doses, the electron-beam irradiation did not produce any significant changes in the values of fruit characteristic parameters. The results lead to the conclusion that the electron-beam irradiation is a good technological solution for fresh fruit processing. (Author) 1 Tab., 7 Refs

    There is an increasing trend for the consumption of fresh fruits and vegetables in developing and developed countries. However, they carry the potential risk of contamination from soil, irrigation water and/or manure and result in food borne outbreaks. Since they are consumed without any treatments, they are the potential sources of contamination. Irradiation is a physical food preservation method; foods are exposed to low doses of ionizing radiation for sterilization or preservation purposes. Irradiation treatment has been shown to effectively enhance the microbial quality and increase the shelf-life by 3-5 times. Also, this treatment reduces the post harvest losses and controls the insects.

  17. Evaluating oil palm fresh fruit bunch processing in Nigeria.

    2018-03-01

    Three routes of oil palm fresh fruit bunch (FFB) processing in Nigeria namely, industrial, small-scale and traditional were compared by means of determining fruit losses associated with each route. The fruits that are not recovered after each process were hand-picked and quantified in terms of crude palm oil (CPO), palm kernel (PK), mesocarp fibre (MF) and palm kernel shell (PKS). The energy value of empty fruit bunch (EFB), MF and PKS were used to determine the value of energy lost for each route. Additionally, the environmental implications of disposal of EFB were estimated, and socio-economics of the industrial and small-scale routes were related. The analysis showed that 29, 18, 75 and 27 kg of CPO, PK, MF and PKS were lost for every 1000 kg of FFB processed with the industrial route, whereas 5.6, 3.2, 1.4 and 5.1 g were lost with the small-scale route, respectively. Approximately 89 kWh and 31 kWh more energy were lost from MF and PKS with the industrial route than the other two routes, respectively. An equivalent of 6670 tonnes carbon dioxide equivalent of methane and nitrogen oxide was released due to the disposal of 29,000 tonnes of EFB from one palm oil mill. The monetary value of lost CPO per 1000 kg of FFB processed in the industrial route is more than the labour cost of processing 1000 kg of FFB in the small-scale route. The advantages of the industrial route are high throughput in terms of FFB processed per hour and high quality of CPO; however, high fruit loss is associated with it and therefore, the poorly threshed EFB is recommended to be fed into the small-scale route.

  18. Antifungal Edible Coatings for Fresh Citrus Fruit: A Review

    Directory of Open Access Journals (Sweden)

    Lluís Palou

    2015-12-01

    Full Text Available According to their origin, major postharvest losses of citrus fruit are caused by weight loss, fungal diseases, physiological disorders, and quarantine pests. Cold storage and postharvest treatments with conventional chemical fungicides, synthetic waxes, or combinations of them are commonly used to minimize postharvest losses. However, the repeated application of these treatments has led to important problems such as health and environmental issues associated with fungicide residues or waxes containing ammoniacal compounds, or the proliferation of resistant pathogenic fungal strains. There is, therefore, an increasing need to find non-polluting alternatives to be used as part of integrated disease management (IDM programs for preservation of fresh citrus fruit. Among them, the development of novel natural edible films and coatings with antimicrobial properties is a technological challenge for the industry and a very active research field worldwide. Chitosan and other edible coatings formulated by adding antifungal agents to composite emulsions based on polysaccharides or proteins and lipids are reviewed in this article. The most important antifungal ingredients are selected for their ability to control major citrus postharvest diseases like green and blue molds, caused by Penicillium digitatum and Penicillium italicum, respectively, and include low-toxicity or natural chemicals such as food additives, generally recognized as safe (GRAS compounds, plant extracts, or essential oils, and biological control agents such as some antagonistic strains of yeasts or bacteria.

    Healthy food distribution programs that allow small retailers to purchase fresh fruits and vegetables at wholesale prices may increase the profitability of selling produce. While promising, little is known about how these programs affect the availability of fresh fruits and vegetables in underserved communities. This study examined the impacts of a healthy food distribution program in Los Angeles County over its first year of operation (August 2015-2016). Assessment methods included: (1) a brief survey examining the characteristics, purchasing habits, and attitudes of stores entering the program; (2) longitudinal tracking of sales data examining changes in the volume and variety of fruits and vegetables distributed through the program; and (3) the collection of comparison price data from wholesale market databases and local grocery stores. Seventeen stores participated in the program over the study period. One-fourth of survey respondents reported no recent experience selling produce. Analysis of sales data showed that, on average, the total volume of produce distributed through the program increased by six pounds per week over the study period (95% confidence limit: 4.50, 7.50); trends varied by store and produce type. Produce prices offered through the program approximated those at wholesale markets, and were lower than prices at full-service grocers. Results suggest that healthy food distribution programs may reduce certain supply-side barriers to offering fresh produce in small retail venues. While promising, more work is needed to understand the impacts of such programs on in-store environments and consumer behaviors.

    The influences of processing and storage on the quality indices and nutritional content of fresh-cut fruits were evaluated in comparison to whole fruits stored for the same duration but prepared on the day of sampling. Fresh-cut pineapples, mangoes, cantaloupes, watermelons, strawberries, and kiwifruits and whole fruits were stored for up to 9 days in air at 5 degrees C. The postcutting life based on visual appearance was shorter than 6 days for fresh-cut kiwifruit and shorter than 9 days for fresh-cut pineapple, cantaloupe, and strawberry. On the other hand, fresh-cut watermelon and mango pieces were still marketable after 9 days at 5 degrees C. Losses in vitamin C after 6 days at 5 degrees C were spoil before any significant nutrient loss occurs.

    Full Text Available Introduction: In developing country like India, street foods such as salads and fresh cut fruits are widely consumed. Among all street foods, fruit juices are common beverages, consumed more because of higher consumer preference both in terms of taste and health. Moreover, there is a dearth of Indian studies on contamination of street vended fruit juices. Aim: To determine the pH and specific microorganisms in freshly squeezed street vended fruit juices. Materials and Methods: Four fruit juices i.e., Grapes, Sweet Lime, Pineapple and Sapota were chosen for the study. Juices were collected in summer season in months between April and June 2013. Ten samples of 50 ml each fruit juice was collected in sterile bottles from various street vendors of Dilshuknagar area of Hyderabad city. Transportation of samples to Food Toxicology laboratory, National Institute of Nutrition was done in the ice box and processing was done within 2–4 h. Results: All juices showed bacterial contamination except one sample of grape juice. Pineapple juice samples showed the high bacterial contamination with all samples positive for fecal coliforms and Shigella spp. (100%. Salmonella spp. was detected only in one sample of Sapota juice (10%. Significant difference among fruit juices for prevalence of microorganisms was seen only for Escherichia coli (P = 0.03 with least count in Grape juice (20%. Conclusion: Freshly squeezed street vended fruit juices were contaminated with pathogenic bacteria, which significantly attributed to public health problem.

    Consumption of fruits and vegetables (F/V) among elementary school-aged children remains inadequate, especially among low-income children. The US Department of Agriculture's Fresh Fruit and Vegetable Program (FFVP) provides F/V as snacks to children during the school day, outside of school meals. School-based initiatives are successful in changing behaviors in school settings; however, their influence on behaviors outside of schools needs investigation. To examine whether FFVP participation is associated with F/V requests at stores, self-efficacy to ask for and choose F/V at home, and F/V consumption. Cross-sectional study. Fourth graders in six classrooms (n=296) from three urban, low-income school districts in Phoenix, AZ, were surveyed during 2015; one FFVP and one non-FFVP school from each district that were similar in school size, percent free/reduced-price meal eligibility, and race/ethnicity of enrolled students were selected. Children's self-reported F/V requests during shopping, their self-efficacy to ask for and choose F/V at home, and F/V consumption on the previous day (non-FFVP school day) were measured using questions adapted from validated surveys. Multivariable mixed-effect regression models, adjusting for clustering of students within classes and classes within schools were explored. In models adjusting for individual-level factors (ie, age and sex) only, several significant positive associations were observed between school FFVP participation and healthier F/V outcomes. After additionally adjusting for school-level factors (ie, total enrollment and % Hispanic/Latino students) significant associations were observed between school FFVP participation and more requests for vegetables during shopping (Pvegetables at home (P=0.004), stronger preferences for vegetables (Pfruit (P=0.006).

E. coli, Klebsiella pneumoniae, Enterococcus casseliflavus, and Enterobacter cloacae were the most abundant species; many are known as opportunistic pathogens which may raise concern to improve the microbial quality of fresh produce. Phylogenetic trees showed no relationship between clustering of the isolates based on the 16S rRNA gene and the original countries of fresh produce. Intercountry passage of opportunistic pathogens in fresh produce cannot be ruled out, which requires better management.

    There is a processing need for a fast, easy and accurate classification system for oil palm fruit ripeness. Such a system will be invaluable to farmers and plantation managers who need to sell their oil palm fresh fruit bunch (FFB) for the mill as this will avoid disputes. In this paper,a new approach was developed under the name of expert rules-based systembased on the image processing techniques results of thethree different oil palm FFB region of interests (ROIs), namely; ROI1 (300x300 pixels), ROI2 (50x50 pixels) and ROI3 (100x100 pixels). The results show that the best rule-based ROIs for statistical colour feature extraction with k-nearest neighbors (KNN) classifier at 94% were chosen as well as the ROIs that indicated results higher than the rule-based outcome, such as the ROIs of statistical colour feature extraction with artificial neural network (ANN) classifier at 94%, were selected for further FFB ripeness inspection system

    Antioxidant vitamins have been postulated as a protective factor in asthma. The associations between the frequency of fresh fruit consumption in summer, and the prevalence of self-reported asthma symptoms were investigated. The analysis was based on 5,582 males and 5,770 females, born in England, Wales and Scotland between March 3-9, 1958 and aged 33 yrs at the time of survey. The 12-month period prevalence of wheeze and frequent wheeze were inversely associated with frequent intakes of fresh fruit and salad/raw vegetables and positively associated with smoking and lower social class. After adjustment for mutual confounding and sex, associations with smoking persisted, but those with social class and salad/raw vegetable consumption lost significance. The frequency of fresh fruit intake was no longer associated with wheeze after adjustment, but was inversely associated with frequent wheeze and speech-limiting attacks. The association with frequent wheeze differed significantly between smoking groups (never, former, current) and appeared to be confined to exsmokers and current smokers. These findings support postulated associations between infrequent fresh fruit consumption and the prevalence of frequent or severe asthma symptoms in adults. Associations appeared to be restricted to smokers, with effect modification as a more likely explanation of this pattern than residual confounding by smoking.

    Full Text Available Fresh date fruits, especially Barhi cultivar, are favored and widely consumed at the Khalal maturity stage (first color edible stage. These fruits are seasonal and perishable and there is a need for extending their shelf life. This study evaluates two different freezing methods, namely cryogenic freezing using liquid nitrogen and conventional deep freezing on preserving the quality and stability of date fruits (cv. Barhi at Khalal maturity stage. Fresh date fruits (cv. Barhi at Khalal stage were frozen utilizing the two methods. The produced frozen dates were stored under frozen storage conditions for nine months (at −20 °C and −40 °C for the conventional and cryogenic freezing, respectively. Color values, textural properties (hardness, elasticity, chewiness and resilience, and nutrition attributes (enzymes and sugars for fresh dates before freezing and for the frozen dates were measured every three months during the frozen storage. Color values of the frozen dates were affected by the freezing method and the frozen storage period. There are substantial differences in the quality of the frozen fruits in favor of cryogenic freezing compared to the conventional slow freezing. The results revealed a large disparity between the times of freezing of the two methods. The freezing time accounted to 10 min in the cryogenic freezing method, whereas it was 1800 min for the conventional slow freezing system.

    Since about 1990, the amount of commercially irradiated food products available worldwide has increased. Commercial irradiation of foods has been allowed in Brazil since 1973 and now more than 20 different food products are approved. Among these products are a number of fresh fruits which may be irradiated for insect disinfestation, to delay ripening and to extend shelf-life. Today, there is a growing interest to apply radiation for the treatment of fruits instead of using fumigation or e.g. vapour-heat treatments, and an increased international trade in irradiated fruits is expected. To ensure free consumer choice, methods to identify irradiated foods are highly desirable. In this work, three detection methods for irradiated fruits have been employed: DNA Comet Assay, the half-embryo test and ESR. Both electron-beam (e-beam) and gamma rays were applied in order to compare the response with these two different kinds of radiation. Fresh fruits such as oranges, lemons, apples, watermelons and tomatoes were irradiated with doses in the range 0, 0.50, 0.75, 1.0, 2.0 and 4.0 kGy. For analysis, the seeds of the fruits were utilized. Both DNA Comet Assay and the half-embryo test enabled an easy identification of the radiation treatment. However, under our conditions, ESR measurements were not satisfactory

  7. Ionizing radiation treatment to improve postharvest life and maintain quality of fresh guava fruit

    We investigated the potential of ionizing radiation for improving physiological responses, quality, and storage time of fresh guava fruit. Ionizing radiation treatment suppressed the respiration and ethylene production rates and thus retarded the process of fruit ripening during storage. Irradiation treatment also retarded the physical and biochemical changes associated with ripening such as firmness, titratable acidity, soluble solids content, and vitamin C during storage, but for doses higher than 0.25 kGy the vitamin C content decreased. The positive effects of ionizing radiation treatment on delayed fruit ripening and other quality attributes diminished during 22 days of storage at 10 deg. C. Thus, a combination of ionizing radiation with low-temperature storage (10 deg. C) did not have much synergistic effect on storage life and quality of guava fruit. In conclusion, ionizing radiation treatment of guava fruit with 0.25 kGy dose increased the postharvest life by 3-4 days, maintained fruit quality, and reduced the decay incidence. The optimal dose (0.25 kGy) for postharvest life extension of guava fruit may be exploited to provide phytosanitary security against many insect pests including fruit flies

  8. Advances in edible coatings for fresh fruits and vegetables: a review.

    2013-01-01

    Edible coatings are an environmentally friendly technology that is applied on many products to control moisture transfer, gas exchange or oxidation processes. Edible coatings can provide an additional protective coating to produce and can also give the same effect as modified atmosphere storage in modifying internal gas composition. One major advantage of using edible films and coatings is that several active ingredients can be incorporated into the polymer matrix and consumed with the food, thus enhancing safety or even nutritional and sensory attributes. But, in some cases, edible coatings were not successful. The success of edible coatings for fresh products totally depends on the control of internal gas composition. Quality criteria for fruits and vegetables coated with edible films must be determined carefully and the quality parameters must be monitored throughout the storage period. Color change, firmness loss, ethanol fermentation, decay ratio and weight loss of edible film coated fruits need to be monitored. This review discusses the use of different edible coatings (polysaccharides, proteins, lipids and composite) as carriers of functional ingredients on fresh fruits and vegetables to maximize their quality and shelf life. This also includes the recent advances in the incorporation of antimicrobials, texture enhancers and nutraceuticals to improve quality and functionality of fresh-cut fruits. Sensory implications, regulatory status and future trends are also reviewed.

    The use of edible films and coatings is an environmentally friendly technology that offers substantial advantages for shelf-life increase of many food products including fruits and vegetables. The development of new natural edible films and coatings with the addition of antimicrobial compounds to preserve fresh and minimally processed fruits and vegetables is a technological challenge for the industry and a very active research field worldwide. Antimicrobial agents have been successfully added to edible composite films and coatings based on polysaccharides or proteins such as starch, cellulose derivatives, chitosan, alginate, fruit puree, whey protein isolated, soy protein, egg albumen, wheat gluten, or sodium caseinate. This paper reviews the development of edible films and coatings with antimicrobial activity, typically through the incorporation of antimicrobial food additives as ingredients, the effect of these edible films on the control of target microorganisms, the influence of antimicrobial agents on mechanical and barrier properties of stand-alone edible films, and the effect of the application of antimicrobial edible coatings on the quality of fresh and fresh-cut fruits and vegetables.

    Schizandra chinensis Baillon, or omija, is a fruit native to northeast Asia that is cultivated in South Korea and China. Fresh omija fruit has been used in beverages, traditional East Asian medicine and cosmetics because of its complex flavor and pharmacological effectiveness. The objective of this study was to analyze residue levels of 33 kinds of pesticides on fresh omija fruits and in omija juices produced in South Korea. A risk assessment of the pesticides in omija juice was conducted by calculating EDI and ADI. Most of the pesticide levels were below the LOD in fresh omija fruits. Among the detected compounds, the most frequently detected pesticide was ethoprophos. The EDIs of ethoprophos, pendimethalin and hexaconazole were 5.89E-03, 7.08E-04 and 4.73E-05, respectively. The percent of EDI to ADI of ethoprophos, pendimethalin and hexaconazole was 28.0%, 13.6% and 4.5%, respectively. The results of this research concluded that the detected pesticides are not harmful to human beings. Published by Elsevier Ltd.

    The results of electron paramagnetic resonance (EPR) study on fresh fruits (whole pulp of pears, apples, peaches, apricots, avocado, kiwi and mango) before and after gamma-irradiation are reported using two drying procedures before EPR investigation. In order to remove water from non-irradiated and irradiated samples of the first batch, the pulp of fresh fruits is pressed, and the solid residue is washed with alcohol and dried at room temperature. The fruits of the second batch are pressed and dried in a standard laboratory oven at 40 deg. C. The results obtained with both drying procedures are compared. All samples under study show a singlet EPR line with g=2.0048{+-}0.0005 before irradiation. Irradiation gives rise to typical 'cellulose-like' EPR spectrum featuring one intensive line with g=2.0048{+-}0.0005 and two very weak satellite lines situated 3 mT at left and right of the central line. Only mango samples show a singlet line after irradiation. The fading kinetics of radiation-induced EPR signal is studied for a period of 50 days after irradiation. When the irradiated fruit samples are stored in their natural state and dried just before each EPR measurement, the satellite lines are measurable for less than 17 days of storage. Irradiated fruit samples, when stored dried, lose for 50 days ca. 40% of their radiation-induced radicals if treated with alcohol or ca. 70% if dried in an oven. The reported results unambiguously show that the presence of the satellite lines in the EPR spectra could be used for identification of radiation processing of fresh fruits, thus extending the validity of European Protocol EN 1787 (2000).

    1985-01-01

    Linear empirical correlations were obtained by applying a statistical model with probative-logarithmic transformation of the experimental data. On such base were predicted the probabal dates of fungal affection to a certain percent and the efficiency of supplementary means to refrigeration storage of fresh fruits (fungicides, ionizing radiation, etc.). Using data with the strawberry cv. Red Gautlet, the main criteria characterizing fruit keeping ability were assessed - dates of fruit decay appearance; of 5% decay, which was accepted for storage; percent of total quantitative losses; percent of fruits preserving their initial quality; mean daily rates of increasing total losses and decreasing the quality for accepted time of storage. The combined grading of these criteria found that fruits of the strawberry cv. Red Gauntlet were preserved best by gamma irradiation in a 2,5 kGy dose together with fruit packing in contractable folio and storage at 10 grad C. Under such conditions the fruits could be stored for 10 days with total quantitative losses (wastage and decay) of 6%, preserving 85% of the initial quality

  17. FRUIT JUICES AS AN ALTERNATIVE TECHNIQUE FOR CONSERVATION OF FRESH-CUT BANANA

    Directory of Open Access Journals (Sweden)

    ANDERSON ADRIANO MARTINS MELO

    2014-01-01

    Full Text Available Browning discoloration after cutting is detrimental for the quality of a number of fruits and vegetables, such as banana, apple, pear, potato, and some roots such as cassava, yam, and others. Browning and softening compromise banana after cut shelf-life in a few hours under cold storage. Therefore, anti-browning compounds have been applied to slices before packing. Some commonly used substances are calcium chloride, ascorbic acid, cysteine and citric acid, in immersed inchemical mixtures. Recent studies have demonstrated the possibility of preserving fresh-cut banana immersed in sweetened fruit juice for relatively longer periods, favoring commercialization. This type of conservation, although widely used in Brazil for fruit salads, consists of a more complex system in a physiological basis, requiring adjustment of the solution parameters, such as sugar concentration, pH and acidity, considering the viability and freshness of the plant tissue. In this short review, we discuss some experimental data and present a new method for preserving fresh-cut banana. Reduction of enzymatic activity, either in temporary dipping treatment or permanent immersion of banana slices is regarded as a key factor for maintaining its quality during cold storage.

    The consumption of fresh-cut fruit has substantially risen over the last few years, leading to an increase in the number of outbreaks associated with fruit. Moreover, consumers are currently demanding wholesome, fresh-like, safe foods without added chemicals. As a response, the aim of this study was to determine if the naturally occurring microorganisms on fruit are "competitive with" or "antagonistic to" potentially encountered pathogens. Of the 97 and 107 isolates tested by co-inoculation with Escherichia coli O157:H7, Salmonella and Listeria innocua on fresh-cut apple and peach, respectively, and stored at 20 °C, seven showed a strong antagonistic capacity (more than 1-log unit reduction). One of the isolates, CPA-7, achieved the best reduction values (from 2.8 to 5.9-log units) and was the only isolate able to inhibit E. coli O157:H7 at refrigeration temperatures on both fruits. Therefore, CPA-7 was selected for further assays. Dose-response assays showed that CPA-7 should be present in at least the same amount as the pathogen to adequately reduce the numbers of the pathogen. From the results obtained in in vitro assays, competition seemed to be CPA-7's mode of action against E. coli O157:H7. The CPA-7 strain was identified as Pseudomonas graminis. Thus, the results support the potential use of CPA-7 as a bioprotective agent against foodborne pathogens in minimally processed fruit. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The aim of this study was to evaluate the microbiological quality and safety of fresh produce at retail level in Korea in order to periodically update information and establish available risks associated with consumption of fresh fruits and vegetables. The samples from different markets located in 3 provinces of South Korea were collected. The protocol in the Korean Food Standards Codex was applied and generic Escherichia coli, coliforms, aerobic mesophilic bacteria (AMB), and yeast and mold (YM) in 360 packaged and unpackaged fresh fruits and vegetables were analyzed. Presence of pathogens was examined using real-time polymerase chain reaction (q-PCR) after enrichment of samples. For all, the microbial counts ranged from 1.7 to 10.6 log cfu/g for AMB, 2.2 to 7.9 log cfu/g for coliforms, and 5.5 to 7.9 log cfu/g for YM. Three lettuce samples were contaminated by E. coli with a bacterial load ranging from 2 to 4 log cfu/g. Salmonella spp. were not detected in any fresh produce. Listeria monocytogenes, E. coli O157:H7, and Staphylococcus aureus were found in 1 (0.6%), 3 (0.8%), and 5 (1.4%) fresh produce samples, respectively. Bacillus cereus (50.3%) and Clostridium perfringens (13.3%) had the highest prevalence. These results indicate the need for employing strict control measures and developing preventive strategies to improve the quality and safety of fresh produce in Korea. © 2018 Institute of Food Technologists®.

    The iodimetric method (Im) is developed for rapid estimation of ascorbic acid from fresh fruit and vegetables. The efficiency of Im was compared with standard with standard dye method (Dm) utilizing a variety of model solutions and aqueous extracts from fresh fruit and vegetables of different colors. The Im presented consistently accurate and precise results from colorless to colored model solutions and from fruit/vegetable extracts with standard deviation (Stdev) in the range of +-0.013 - +-0.405 and +-0.019 - +-0.428 respectively with no significant difference between the replicates. The Dm worked also satisfactorily for colorless model solutions and extracts (Stdev range +-0.235 - +-0.309) while producing unsatisfactory results (+-0.464 - +-3.281) for colored counterparts. Severe discrepancies/ overestimates continued to pileup (52% to 197%) estimating the nutrient from high (3.0 mg/10mL) to low (0.5 mg/10mL) concentration levels, respectively. On the basis of precision and reliability, the Im technique is suggested for adoption in general laboratories for routine estimation of ascorbic acid from fruit and vegetables possessing any shade.

    Foodborne outbreaks associated with fresh fruits and vegetables are on the rise worldwide. Biofilm formation is one of the important traits of pathogens making them strongly attached to substrates as well as express virulence phenotypes. Present study investigates the biofilm forming ability of E. coli and Salmonella sp. isolated from fresh fruits and vegetables. A total of 53 strains, including 35 E. coli and 18 Salmonella sp. isolated from different fruit and vegetable samples were taken into account for the study. Initial screening for biofilm formation was done using Congo Red agar plate test. Results revealed that 22.8% E. coli and 22.2% Salmonella sp. were potential biofilm formers. However, the MTP (Micro-Titre Plate) assay suggested more isolates of both E. coli and Salmonella sp. were moderate to strong biofilm producers. Agar plate diffusion assay with Agrobacterium tumefaciens NTL-4 showed the production of quorum signaling molecules (AHLs) by three isolates of E. coli and one Salmonella sp. Two E. coli isolates showed a significant amount of EPS production indicating higher biofilm forming potential. The Presence of LUX R homologue gene ( sdi A) in two of the Salmonella isolates were confirmed by PCR which demonstrated their potential pathogenicity. Results of the work underline the biofilm forming and potentially virulent capacities of isolates from the surface of fruits and vegetables.

    Young adults are less likely than other adults to consume fruit and vegetables. Fresh Facts is a theory of planned behaviour based intervention designed to promote fruit and vegetable consumption. The present study sought to evaluate Fresh Facts using a randomised controlled trial. Australian young adults (n = 162) were allocated to the Fresh Facts intervention or to the control group in 2011. Intervention participants received automated email messages promoting fruit and vegetable consumption every 3 days over the course of the 1 month intervention. Messages targeted attitude, subjective norm, and perceived behavioural control. Theory of planned behaviour variables and fruit and vegetable intake were measured at baseline and post-intervention (Day 30). Significant increases in attitude and subjective norm relative to control were found among Fresh Facts participants. However, intention, perceived behavioural control and fruit and vegetable consumption did not change as a result of the intervention. Changes in intention reported by each participant between baseline and follow-up were not correlated with corresponding changes in fruit and vegetable consumption. Fresh Facts was not successful in increasing fruit and vegetable consumption. Current evidence does not support the use of the theory of planned behaviour in the design of interventions to increase fruit and vegetable intake in this population. Copyright © 2014 Elsevier Ltd.

    According to national studies conducted in EU countries, fresh fruit and vegetables contribute to almost 50% of the food waste generated by households. This study presents an estimation of this waste flow, differentiating between unavoidable and avoidable waste. The calculation of these two flows serves different purposes. The first (21.1 kg per person per year) provides a measure of the amount of household waste intrinsically linked to the consumption of fresh fruit and vegetables, and which would still be generated even in a zero-avoidable waste future scenario. The second (14.2 kg per person per year) is a quantity that could be reduced/minimised by applying targeted prevention strategies. The unavoidable waste was assessed at product level, by considering the inedible fraction and the purchased amounts of the fifty-one most consumed fruits and vegetables in Europe. The avoidable waste was estimated at commodity group level, based on the results of national studies conducted in six EU member states. Significant differences in the amounts of avoidable and unavoidable waste generated were found across countries, due to different levels of wasteful behaviours (linked to cultural and economic factors) and different consumption patterns (influencing the amount of unavoidable waste generated). The results of this study have implications for policies both on the prevention and the management of household food waste. Copyright © 2018 The Author(s). Published by Elsevier Ltd..

    The main difficulties for Brazilian fruit exports are phytosanitary barriers. Irradiation can be used as a single treatment, part of a multiple treatment or combined with other mitigation measures as a component of a systems approach which would be a treatment for plant pests of quarantine significance. For any kind of industrial irradiation, determining the absorbed doses involves a dosimetry system that covers the absorbed dose range of interest and shall be calibrated before use. Frequently, however, it is useful to also have a radiation sensitive indicator to visually determine whether or not a product has been irradiated. STERIN labels were designed as threshold indicators, where a visual message changes after exposure at or above the threshold indication dose (e.g. 125 Gy, 300 Gy). The aim of this work was to evaluate STERIN label indicators to be used for Brazilian irradiated fresh fruits. (author)

  7. Biodegradable packaging and edible coating for fresh-cut fruits and vegetables

    2015-03-01

    Full Text Available This work focuses on biodegradable packaging and edible coatings applied to fresh-cut fruits and vegetables and their effects on the product quality. Practical applications are mainly limited to the use of biodegradable materials that, however, do not allow full control of the product moisture loss. Better results can be achieved by the combined use of biodegradable packagings with edible coatings and recent research has shown that enrichment with silver montmorillonite nanoparticles may be a promising technique. However, the actual utilization of these materials is still limited, due to the high costs of the raw materials and the limited production.

    The U.S. Department of Agriculture in February 2012 approved the import of fresh pomegranates subjected to irradiation as a quarantine procedure with a minimum absorbed dose of 0.4kGy against different pests. This study evaluated the application of different gamma-irradiation doses (0.4, 1, and 2kGy) in fresh pomegranate fruits and their effect on the chemical and sensory characteristics. The total soluble solids, titratable acidity, and pH values remained unaffected up to 1kGy treatment. Irradiation caused a significant decrease in the total anthocyanins and phenolic content. A strong positive correlation was observed among the antioxidant activities, total phenolics and anthocyanin contents. In general, a stronger preference was shown by sensory panelists for the juice from irradiated fruits. This study provides research-based information about the application of irradiation as a quarantine disinfestation treatment to enhance the marketing and consumer acceptance of pomegranates.

    The study aimed at exploring the safety of various fresh fruit juices, blends and drinks sold in the streets of Multan, Pakistan. The city was divided into 4 zones for the purpose of sample collection. Bacteriological analysis of 72 samples of fresh fruit juices, blends and drinks indicated the presence of total viable counts (2.48 +- 0.16 to 7.91 +- 0.62 log CFU/mL), total coliforms (0.70 +- 0.04 to 4.86 +- 0.29 log CFU/mL) and Escherichia coli (0.6 +- 0.03 to 3.83 +- 0.32 log CFU/mL). Qualitative data depicted apple juice to be highly contaminated with fecal coliforms and Salmonella spp. Coliforms prevalence was highest in Zone IV and Zone II while that of Salmonella spp., in Zone IV and Zone III. The pragmatic levels of contaminants elucidate poor sanitary status of major entities deployed in juice manufacturing process adopted by the street vendors. (author)

    2016-05-01

    Full Text Available Methyl jasmonate (MeJA is a plant growth regulator belonging to the jasmonate family. It plays an important role as a possible airborne signaling molecule mediating intra- and inter-plant communications and modulating plant defense responses, including antioxidant systems. Most assessments of this compound have dealt with post-harvest fruit applications, demonstrating induced plant resistance against the detrimental impacts of storage (chilling injuries and pathogen attacks, enhancing secondary metabolites and antioxidant activity. On the other hand, the interactions between MeJA and other compounds or technological tools for enhancing antioxidant capacity and quality of fruits were also reviewed. The pleiotropic effects of MeJA have raisen numerous as-yet unanswered questions about its mode of action. The aim of this review was endeavored to clarify the role of MeJA on improving pre- and post-harvest fresh fruit quality and health properties. Interestingly, the influence of MeJA on human health will be also discussed.

    Full Text Available Fruits and vegetables comprise an essential part of human diet as they are the major source of dietary nutrients of great importance. Consumption of fruits has been found to counteract many of the chronic diseases, including cancers and cardiovascular diseases. Therefore, recommendations for a balanced diet must include the consumption of fresh fruits and vegetables. Consumers in developing countries have become more concerned about the nutritional and sensory aspects as well as the safety of the food they eat due to growing health awareness. At the same time, consumer demand for convenience products is increasing and so is the demand for fresh-cut fruits and vegetables. Fresh-cut market has expanded considerably in recent years. However, quality and safety of such products are an issue of concern as these products can act as vehicles for transmitting infectious diseases. Furthermore, fresh-cut produce is more susceptible to spoilage and can facilitate rapid growth of spoilage micro-organisms as well as the micro-organisms of public health significance. Nonetheless, keeping in consideration the vast scope of fresh-cut products, this article intends to thoroughly review information about microbiology and public health risks associated with them. Discussions regarding different approaches to extend the shelf life and to minimize the risk of infection associated with their consumption are also included.

    The aim of this study was to determine survival or growth of unadapted, acid-adapted and cold-stressed Salmonella spp., and natural microbiota on fresh-cut dragon fruits at different storage temperatures. Dragon fruits were sliced and spot inoculated with five-strain cocktail of Salmonella spp. at two inoculum levels (2.5 or 5.5 log CFU/g). Inoculated fruits were stored at 28°C for 48h and at 4°C and 12°C for 96 h. Salmonella population significantly increased by 2.4 to 3.0 log CFU/g at low inoculum level, whereas the numbers increased by 0.4 to 0.7 log CFU/g at the high inoculum level on fruits held at 28°C for 48h. Only unadapted and acid-adapted cells grew with 0.7 to 0.9log increase at the low inoculum level at 12°C for 96h. No significant growth was observed at both inoculum levels during storage at 4°C. Overall, acid, starved and cold adaptation of Salmonella spp. did not show significant difference in survival or growth on fresh-cut dragon fruits during storage compared to unadapted control cells. For natural microbiota on the fruit, mesophilic bacterial counts reached to 5-log CFU/g at 28 and 12°C by 9.9 and 52.9h. Similar with Salmonella spp. there was no growth of natural microbiota at 4°C. These results showed that Salmonella spp. could grow on fresh-cut dragon fruits under inappropriate storage conditions, indicating that fresh-cut dragon fruits could be a potential vehicle for salmonellosis. Thus, this study suggests that fresh-cut dragon fruits should be stored at 4°C to ensure the safety as well as to extend the shelf life of fresh-cut dragon fruits. Copyright © 2012 Elsevier B.V.

    Full text: Electron spin resonance (ESR) technique was used to measure the stability of free radicals produced by the irradiation treatment in mangoes and in four spices: black pepper, oregano, 'guajillo' chili and 'morron' chili. The ESR spectra for mangoes were scanned in three different parts from the seeds and were recorded in fresh and dried tissues. The ESR spectra in fresh tissue of no irradiated mangoes, were a sextet line signal produced by Mn 2+ ion and a singlet centered at g = 2.00 produced by the endogenous radical. New resonances were observed in the irradiated samples at 1.5 mT and 3 mT respects to the center line for right and left side. These new resonance signals were-observed for eight days in mangoes treated at 1.00 kGy, and for three days at 0.15 kGy. The resonance due to the irradiation was observed in Iyophilized mangoes only one day after the treatment, in the vacuum dried samples, no new resonances were observed. The triplet signal, as well as the central single line appeared after irradiation in black pepper, morron chili and guajillo chili. These signals were also observed in the irradiated spices at any radiation dose higher than 1.0 kGy. The signals decrease promptly, in ten days after the 'irradiation. It was not possible to observe the triplet signal in oregano, even when the samples were analyzed immediately after irradiation treatment. The only signal observed in irradiated spice was the endogenous radical. This signal increased as the radiation dose increased and decreased during storage time at room temperature. Results showed that free radicals produced in irradiated fresh fruits or dried foods have a quick recombination. It was observed that in the spices the signal remains for several weeks meanwhile only eight days in mangoes. (Author)

    The ripeness of the oil palm Fresh Fruit Bunches (FFB) determines the yield of the oil produced. Traditionally there are two ways to determine FFB ripeness which are the number of loose fruits and the color changes. Nevertheless, one drawback of visual determination is subjective and qualitative judgment. In this study, the FFB ripeness was investigated using laser based image processing technique. The advantages of using this technique are non-destructive, simple and quantitative. The working principle of the investigation is that a FFB is inserted into a light tight box which contains a laser diode and a CMOS camera, the FFB is illuminated, and then an image is recorded. The FFB image recorder was performed on four FFB fractions i.e. F0, F3, F4 and F5 on the front and rear surfaces at three sections. The recorded images are speckled granules that have light intensity variation (bio-speckle imaging). The feature extracted from the specked image is the contrast value obtained from the average gray value intensity and the standard deviation. Based on the contrast values, the four fractions of FFB can be grouped into three levels of ripeness of unripe (F0), ripe (F3) and overripe (F4 and F5) on the front surface of base section of FFB by 75%.

    Neighbourhood differences in access to fresh fruit and vegetables may explain social inequalities in diet. Investigations have focused on variations in cost and availability as barriers to the purchase and consumption of fresh produce; investigations of quality have been neglected. Here we investigate whether produce quality systematically varies by food store type, rural-urban location and neighbourhood deprivation in a selection of communities across Scotland. Cross-sectional survey of twelve fresh fruit and vegetable items in 288 food stores in ten communities across Scotland. Communities were selected to reflect a range of urban-rural settings and a food retail census was conducted in each location. The quality of twelve fruit and vegetable items within each food store was evaluated. Data from the Scottish Executive were used to characterise each small area by deprivation and urban-rural classification. Scotland. Quality of fruit and vegetables within the surveyed stores was high. Medium-sized stores, stores in small town and rural areas, and stores in more affluent areas tended to have the highest-quality fresh fruit and vegetables. Stores where food is secondary, stores in urban settings and stores in more deprived areas tended have the lowest-quality fresh produce. Although differences in quality were not always statistically significant, patterns were consistent for the majority of fruit and vegetable items. The study provides evidence that variations in food quality may plausibly be a micro-environmental mediating variable in food purchase and consumption and help partially explain neighbourhood differences in food consumption patterns.

    Fresh-cut (FC) red pitaya fruit were treated with 5ga.i.l -1 apple polyphenols (APP) and then stored at 20°C for up to 4days to evaluate the effects on attributes. Results showed that FC pitaya fruit with APP treatment showed greater colour retention, delayed softening, reduced loss of soluble solids content, titratable acidity, betacyanin and total phenolics compared with untreated FC fruit. APP treatment also maintained antioxidant activity, as indicated by higher DPPH radical-scavenging activity and reducing power compared with untreated FC pitaya fruit. APP treatment strongly suppressed microbial growth, contributing to improvement of product safety. Because APP is a natural product, we propose that application of APP could be a convenient, safe and low-cost approach to maintain the quality and extend the shelf life of FC red pitaya fruit.

    The consumption of fresh-cut fruits is limited because of the oxidation browning and pathogenic bacteria's growth on the fruit surface. Besides, crack of the fresh-keeping film may shorten the preservation time of fruit. In this work, polyelectrolyte multilayer (PEM) film was fabricated by layer-by-layer (LBL) electrostatic deposition method. The film was made by carboxy methylcellulose sodium (CMC) and chitosan (CS). The as-prepared PEM film had good anti-oxidative and antibacterial capability. It inhibited the growth of Gram-negative bacteria and the antibacterial rate was more than 95%. The stratified structure and linear increase of the absorbance in the film verified a linear increase of film thickness. The slight scratched film could self-heal rapidly after the stimulation of water whatever the layer number was. Moreover, the film could heal cracks whose width was far bigger than the thickness. The application of PEM film on fresh-cut apples showed that PEM film had good browning, weight loss and metabolic activity inhibition ability. These results showed that the PEM film is a good candidate as edible film in fresh-cut fruits applications.

    Ecological models of health suggest that to effectively prevent chronic disease, community food environments must support healthy eating behaviors. However, disparities in access to healthy foods persist in the United States. The Farm Fresh Market (FFM) was a fruit and vegetable market that sold low-cost fresh produce in Cobb County, Georgia in 2014. This case study describes the development of the FFM through a community engagement process and presents evaluation results from the project's pilot implementation. Community engagement strategies included forming a community advisory board, conducting a needs assessment, and contracting with a community-based organization to implement the FFM. In the pilot year, the FFM served an average of 28.7 customers and generated an average of $140.20 in produce sales per market day. Most returning customers lived in the local community and reported a range of socioeconomic backgrounds. Most returning customers strongly agreed that the FFM made it easier (69.0%) and less expensive (79.0%) for them to buy fresh fruits and vegetables, reported that they ate more vegetables (65.0%) and fruit (55.0%) as a result of the FFM, and reported that they were very satisfied with the FFM overall (92.0%). Results from this community case study underscore the importance of engaging communities in the development of community food environment interventions. Results also suggest that the FFM initiative was a feasible and acceptable way to respond to the community-identified public health priority of increasing access to healthy foods.

    Fresh-cut luffa (Luffa cylindrica) fruits commonly undergo browning. However, little is known about the molecular mechanisms regulating this process. We used the RNA-seq technique to analyze the transcriptomic changes occurring during the browning of fresh-cut fruits from luffa cultivar ‘Fusi-3’. Over 90 million high-quality reads were assembled into 58,073 Unigenes, and 60.86% of these were annotated based on sequences in four public databases. We detected 35,282 Unigenes with significant hits to sequences in the NCBInr database, and 24,427 Unigenes encoded proteins with sequences that were similar to those of known proteins in the Swiss-Prot database. Additionally, 20,546 and 13,021 Unigenes were similar to existing sequences in the Eukaryotic Orthologous Groups of proteins and Kyoto Encyclopedia of Genes and Genomes databases, respectively. Furthermore, 27,301 Unigenes were differentially expressed during the browning of fresh-cut luffa fruits (i.e., after 1–6 h). Moreover, 11 genes from five gene families (i.e., PPO, PAL, POD, CAT, and SOD) identified as potentially associated with enzymatic browning as well as four WRKY transcription factors were observed to be differentially regulated in fresh-cut luffa fruits. With the assistance of rapid amplification of cDNA ends technology, we obtained the full-length sequences of the 15 Unigenes. We also confirmed these Unigenes were expressed by quantitative real-time polymerase chain reaction analysis. This study provides a comprehensive transcriptome sequence resource, and may facilitate further studies aimed at identifying genes affecting luffa fruit browning for the exploitation of the underlying mechanism.

    Climate change effects and variability have been studied by many researchers in diverse geophysical fields. Malaysia produces large volume of palm oil, the effects of climate change on hydrological parameters (rainfall and precipitation) could have adverse effects on palm oil fresh fruit bunch (FFB) production with implications at both local and international market. It is important to understand the effects of climate change on crop yield to adopt new cultivation techniques and guaranteeing food security globally. Based on this background, the paper’s objective is to investigate the effects of rainfall and temperature pattern on crop yield (FFB) within five years period (2013 - 2017) at Batu Pahat District. The Man - Kendall rank technique (trend test) and statistical analyses (correlation and regression) were applied to the dataset used for the study. The results reveal that there are variabilities in rainfall and temperature from one month to the other and the statistical analysis reveals that the hydrological parameters have an insignificant effect on crop yield.

Increasing temperature usually results in accelerated loss of quality and shelf-life reduction, which is not physically visible until too late in the supply chain to adjust logistics to match shelf life. A blackberry study showed that temperatures inside pallets varied significantly and 57% of the berries arriving at the packinghouse did not have enough remaining shelf life for the longest supply routes. Yet, the advanced shelf-life loss was not physically visible. Some of those pallets would be sent on longer supply routes than necessary, creating avoidable waste. Other studies showed that variable pre-cooling at the centre of pallets resulted in physically invisible uneven shelf life. We have shown that using simple temperature measurements much waste can be avoided using 'first expiring first out'. Results from our studies showed that shelf-life prediction should not be based on a single quality factor as, depending on the temperature history, the quality attribute that limits shelf life may vary. Finally, methods to use air temperature to predict product temperature for highest shelf-life prediction accuracy in the absence of individual sensors for each monitored product have been developed. Our results show a significant reduction of up to 98% in the root-mean-square-error difference between the product temperature and air temperature when advanced estimation methods are used.

    Ripeness classification of oil palm fresh fruit bunches (FFBs) during harvesting is important to ensure that they are harvested during optimum stage for maximum oil production. This paper presents the application of color vision for automated ripeness classification of oil palm FFB. Images of oil palm FFBs of type DxP Yangambi were collected and analyzed using digital image processing techniques. Then the color features were extracted from those images and used as the inputs for Artificial Neural Network (ANN) learning. The performance of the ANN for ripeness classification of oil palm FFB was investigated using two methods: training ANN with full features and training ANN with reduced features based on the Principal Component Analysis (PCA) data reduction technique. Results showed that compared with using full features in ANN, using the ANN trained with reduced features can improve the classification accuracy by 1.66% and is more effective in developing an automated ripeness classifier for oil palm FFB. The developed ripeness classifier can act as a sensor in determining the correct oil palm FFB ripeness category.

    Dietary intake among children in the United States falls short of national recommendations. Schools can play an important role in improving children's preferences and food consumption patterns. The US Department of Agriculture's Fresh Fruit and Vegetable Program (FFVP) aims to improve children's nutrient intake patterns by offering fresh fruits and vegetables as snacks outside the reimbursable meals programs in elementary schools that serve large numbers of low-income children. Using a nationally representative sample of public elementary schools, this cross-sectional study investigated FFVP participation patterns among schools by demographic and school characteristics. Further, the study investigated the association between FFVP participation and availability of fresh fruits, salads, and vegetables at lunch as reported by school administrators and foodservice staff. Data collected via a mail-back survey from 620 public elementary schools participating in the National School Lunch Program during 2009-2010 were analyzed. Almost 70% of the FFVP-participating schools had a majority of students (>50%) eligible for free and reduced-cost meals. Participating in US Department of Agriculture Team Nutrition Program and having a registered dietitian or a nutritionist on staff were significantly associated with FFVP participation. Based on the results from logistic regression analyses schools participating in the FFVP were significantly more likely (odds ratio 2.07; 95% CI 1.12 to 3.53) to serve fresh fruit during lunch meals. Slightly >25% of public elementary schools across the United States participated in the FFVP, and participation was associated with healthier food availability in school lunches.

    Two fresh (fresh cubic pieces, fresh puree) and two dried (dried cubic pieces, dried powder) products were prepared from a homogenous mango fruit batch to obtain four samples differing in texture. The aromatic profiles were determined by SAFE extraction technique and GC-MS analysis. VOCs released during consumption were trapped by a retronasal aroma-trapping device (RATD) and analysed by GC-MS. Twenty-one terpenes and one ester were identified from the exhaled nose-space. They were amongst the major mango volatile compounds, 10 of which were already reported as being potential key flavour compounds in mango. The in vivo release of aroma compounds was affected by the matrix texture. The intact samples (fresh and dried cubic pieces) released significantly more aroma compounds than disintegrated samples (fresh puree, dried powder). The sensory descriptive analysis findings were in close agreement with the in vivo aroma release data regarding fresh products, in contrast to the dried products. Copyright © 2017 Elsevier Ltd.

    Fruits and vegetables are major vehicles for transmission of food-borne enteric viruses since they are easily contaminated at pre- and postharvest stages and they undergo little or no processing. However, commonly used sanitizers are relatively ineffective for removing human norovirus surrogates from fresh produce. In this study, we systematically evaluated the effectiveness of surfactants on removal of a human norovirus surrogate, murine norovirus 1 (MNV-1), from fresh produce. We showed that a panel of surfactants, including sodium dodecyl sulfate (SDS), Nonidet P-40 (NP-40), Triton X-100, and polysorbates, significantly enhanced the removal of viruses from fresh fruits and vegetables. While tap water alone and chlorine solution (200 ppm) gave only <1.2-log reductions in virus titer in all fresh produce, a solution containing 50 ppm of surfactant was able to achieve a 3-log reduction in virus titer in strawberries and an approximately 2-log reduction in virus titer in lettuce, cabbage, and raspberries. Moreover, a reduction of approximately 3 logs was observed in all the tested fresh produce after sanitization with a solution containing a combination of 50 ppm of each surfactant and 200 ppm of chlorine. Taken together, our results demonstrate that the combination of a surfactant with a commonly used sanitizer enhanced the efficiency in removing viruses from fresh produce by approximately 100 times. Since SDS is an FDA-approved food additive and polysorbates are recognized by the FDA as GRAS (generally recognized as safe) products, implementation of this novel sanitization strategy would be a feasible approach for efficient reduction of the virus load in fresh produce.

    This study examined Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participant use and satisfaction with jarred baby foods, assessed preference for cash value vouchers (CVVs) for fruits and vegetables vs jarred baby foods, and examined whether preferences varied among selected ethnic groups. A survey of California WIC participants and statewide redemption data were used. Participants reported high satisfaction with the CVV for fruits and vegetables and jarred baby foods, with statistically significant variation across ethnic groups. About two thirds of all participants reported a preference for CVVs for fruits and vegetables over jarred baby foods. Redemption data indicated declining redemption rates for jarred fruits and vegetables with increasing age of the infant across all ethnic groups. Although the addition of jarred fruits and vegetables to the food package for infants ages 6-11 months was well received, many caregivers want the option to choose between jarred foods and fresh fruits and vegetables.

    Sulfur dioxide residues in 20 kinds of products collected from 23 provinces of China (Jilin, Beijing, Shanxi, Shandong, Henan, Hebei, Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, Yunnan, Guizhou, Hunan, Hubei, Chongqing, Sichuan, Gansu, Neimenggu, Xinjiang and Hainan) were analysed, and a health risk assessment was performed. The detection rates of sulfur dioxide residues in fresh vegetables, fresh fruits, dried vegetables and dried fruits were 11.1-95.9%, 12.6-92.3%, 70.3-80.0% and 26.0-100.0%, respectively; the mean concentrations of residues were 2.7-120.8, 3.8-35.7, 26.9-99.1 and 12.0-1120.4 mg kg -1 , respectively. The results indicated that fresh vegetables and dried products are critical products; the daily intakes (EDIs) for children were higher than others; the hazard indexes (HI) for four groups were 0.019-0.033, 0.001-0.005, 0.007-0.016 and 0.002-0.005 at P50, respectively. But the HI was more than 1 at P99 by intake dried fruits and vegetables. Although the risk for consumers was acceptable on the whole, children were the most vulnerable group. Uncertainty and sensitivity analyses indicated that the level of sulfur dioxide residues was the most influential variable in this model. Thus, continuous monitoring and stricter regulation of sulfites using are recommended in China.

    Processing of fruits and vegetables generates physiological stresses in the still living cut tissue, leading to quality deterioration and shorter shelf life as compared with fresh intact produces. Several strategies can be implemented with the aim to reduce the rate of deterioration of fresh-cut commodities. Such strategies include low temperature maintenance from harvest to retail and the application of physical and chemical treatments such as modified atmosphere packaging (MAP) with low O 2 and high CO 2 levels and antioxidant dips. Other technologies such as edible coatings with natural additives, new generation of coatings using nanotechnological solutions such as nanoparticles, nanoencapsulation, and multilayered systems, and nonconventional atmospheres such as the use of pressurized inert/noble gases and high levels of O 2 have gained a lot of interest as a possibility to extend the shelf life of minimally processed fruits and vegetables. However, the high perishability of these products challenges in many cases their marketability by not achieving sufficient shelf life to survive the distribution system, requiring the combination of treatments to assure safety and quality. This review reports the recent advances in the use of MAP, edible coatings, and the combined effect of both technologies to extend the shelf life of fresh-cut fruits and vegetables.

    In developing countries such as Indonesia, as much as 40% of total vegetables and fruits production becomes waste because of lack refrigeration. This condition also contributes a food crisis problem besides other factor such as, climate change and number of population. Cold chain system that will be modelled in this study is for vegetables and fruits and refrigeration system as the main devices. In future, this system will play an important role for the food crisis solution where fresh food can be distributed very well with significant low waste. The fresh food also can be kept with good quality and hygienist (bacteria contaminated). Cold Chain model will be designed using refrigeration components including, pre cooling chiller, cold room, and truck refrigeration. This study will be conducted by survey and observation di around Bali Province focus on vegetables and fruits production center. Interviews and questionnaire will be also done to get some information about the conventional distribution obstacles and problem. Distribution mapping will be developed and created. The data base of the storage characteristic of the fruits and vegetable also collected through experiment and secondary data. Depend on the mapping and data base can be developed a cold chain model that has the best performance application. The model will be can directly apply in Bali to get eligible cold chain in Bali. The cold chain model will be compared with the conventional distribution system using ALCC/LCC method and also others factor and will be weighted to get better results.

    Fresh-cut produce represents a good method to save about 25% of the kiwifruit not useful to meet the fresh fruit-marketing standard due to improper size and shape. For that reason, fresh-cut kiwifruit has been extensively studied. However, the comprehension of the influence of some aspects of cultivation might further increase the shelf life as well as the nutritional values of that fruit. This study explored the hypothesis that kiwifruits grown fully exposed to sunlight or partially shaded differently perform upon storage as whole fruit and as minimally processed produce. Flesh firmness (FF), total solids soluble (SSC), ascorbate (AAT), flavonoids (TFO), and phenols (TF) contents were evaluated in sliced and whole fruit upon 3 days of storage at 4 °C after 75 days of cold chamber storage at 0 °C. The activities of two enzymes related to the softening process, polygalacturonase (PG) and pectinmethylesterase (PME), were evaluated as well. FF and SSC were constitutively higher in sun-exposed fruit, and those characteristics remained higher during the storage as whole fruit. Greater constitutive content of AAT, TFO, and TP was found in sun-exposed whole fruit, although after cutting the reduction in their content was significantly lower in shaded fruits. PME and PG activities were higher only in whole shaded fruits, whereas no relevant differences occurred after cutting. In summary, sun-exposed fruits were more suitable for the fresh-fruit market, whereas the shaded counterpart displayed a good predisposition for use as fresh-cut produce, maintaining similar fruit maturity properties but higher nutraceutical values when sliced than fruit grown under full sun.

    Changing the food environment in low-income communities may be an effective way to increase the consumption of fruits and vegetables by low-income consumers. This study examines the impacts of a pilot study that increases the availability of fresh produce in a convenience store in a low-income neighborhood not served by a supermarket. Two hypotheses based on theories of technology adoption are tested regarding the lack of fresh produce in low-income neighborhood stores: the first is that high fixed costs present a barrier for store owners in developing produce sections; the second is that there is insufficient consumer demand to cover the variable costs of a fresh produce section. The impacts of changing the food environment on store owners and the consumer response to environmental change are measured through weekly inventories of fresh produce. The results show that fixed costs are one barrier for store owners and that although the consumer response is sufficient to cover the direct costs of operating the produce case, it is not enough to cover variable management costs. Consequently, alternative management paradigms or venues may offer a better method to meet the demand for fresh produce by low-income consumers to promote better health through healthier diets in low-income communities.

    This study aimed to promote vermicomposting performance for recycling fresh fruit and vegetable wastes (FVWs) and to assess microbial population and community of final products. Five fresh FVWs including banana peels, cabbage, lettuce, potato, and watermelon peels were chosen as earthworms' food. The fate test of earthworms showed that 30 g fresh FVWs/day was the optimal loading and the banana peels was harmful for the survival of Eisenia fetida. The followed vermicomposting test revealed lower contents of total carbon and weaker microbial activity in final vermicomposts, relative to those in compared systems without earthworms worked. The leachate from FVWs carried away great amounts of nutrients from reactors. Additionally, different fresh FVWs displayed dissimilar stabilization process. Molecular biological approaches revealed that earthworms could broaden bacterial diversity in their products, with significant greater populations of actinobacteria and ammonia oxidizing bacteria than in control. This study evidences that vermicomposting efficiency differs with the types and loadings of fresh FVWs and vermicomposts are rich in agricultural probiotics.

    Modified atmosphere packaging (MAP) for fresh 'Carabao' mango was optimized with respect to the number of pinholes needed for a fixed respiration rate, fill weight, oxygen transmission rate (OTR), and bag surface area. Computer simulations showed that 38-mm polyethylene or 20-mm Zeolite film with 52 or 44 pinholes, respectively, could be used for packing 5 kg of fruit in a bag with a surface area of approximately 0.80 sq m if held at 12.5 deg C. Subsequent laboratory trials using fruits irradiated at 150-250 Gy showed that 50 pinholes made with a 26-gauge cold needle could be used for both films; O2 levels during storage were close to the recommended levels of 3-5%. Pilot-scale trials using fruits harvested during the on and off-season show that both irradiation at 150-250 Gy and MAP could retard ripening and reduce softening. After 4 wk of storage at 12.5 deg C, MAP fruits were at a half-ripe and slightly-firm stage of ripeness, with minimal development of disease. Sensory tests at the table-ripe stage showed that irradiated MAP-stored fruits were acceptable

    Full Text Available The use of unsuitable fruits for marketing in fresh, represents an area with great economic potential. In the regions of Colombia where is produced cape gooseberry it is necessary to consider and develop processing alternatives of this fruit, because the losses in harvest and postharvest of gooseberry in the country, can reach up to 45% of the total production. In this research, it was developed pulp, jam and nectar of cape gooseberry ecotype Colombia with cracked and soft fruits, from Ventaquemada and Cienega, municipalities of the department of Boyaca. The results of this research have applications for the producing regions of cape gooseberry in Colombia that suffer from loss of fruit by cracking and softening. There were three formulations of each by-product, by varying the content of pulp in the final product and the physiochemical characterization, microbiological and sensorial. Finally, it was calculated the cost of each most accepted by-product by the panel. The results showed that at a microbiological l and physic-chemical level, the sub-products meet the regulations. At sensory level, the most widely accepted pulp pasteurized with sugar, the most accepted nectar was the formulation with 20% of pulp and the most widely accepted jam was the formulation with 50% of pulp. The cost to process 1 kg of fruit was 3,11 USD for pulp, 3,36 USD for nectar and 3,66 USD for jam.

    2006-01-01

    A total of 128 Bacillus cereus-like strains isolated from fresh fruits and vegetables for sale in retail shops in Denmark were characterized. Of these strains, 39% (50/128) were classified as Bacillus thuringiensis on the basis of their content of cry genes determined by PCR or crystal proteins visualized by microscopy. Random amplified polymorphic DNA analysis and plasmid profiling indicated that 23 of the 50 B. thuringiensis strains were of the same subtype as B. thuringiensis strains used as commercial bioinsecticides. Fourteen isolates were indistinguishable from B. thuringiensis subsp. kurstaki HD1 present in the products Dipel, Biobit, and Foray, and nine isolates grouped with B. thuringiensis subsp. aizawai present in Turex. The commercial strains were primarily isolated from samples of tomatoes, cucumbers, and peppers. A multiplex PCR method was developed to simultaneously detect all three genes in the enterotoxin hemolysin BL (HBL) and the nonhemolytic enterotoxin (NHE), respectively. This revealed that the frequency of these enterotoxin genes was higher among the strains indistinguishable from the commercial strains than among the other B. thuringiensis and B. cereus-like strains isolated from fruits and vegetables. The same was seen for a third enterotoxin, CytK. In conclusion, the present study strongly indicates that residues of B. thuringiensis-based insecticides can be found on fresh fruits and vegetables and that these are potentially enterotoxigenic.

    This study aimed to investigate the effect of earthworms on physicochemical and microbial properties during vermicomposting of fresh fruit and vegetable wastes (FVW) by contrasting two decomposing systems of FVW with and without earthworms for 5weeks. Compared to control treatment (without earthworms), vermicomposting treatment resulted in a rapid decrease of electrical conductivity and losses of total carbon and nitrogen from the 2nd week. Quantitative PCR displayed that earthworms markedly enhanced bacterial and fungal densities, showing the higher values than control, during the whole decomposition process. In addition, denaturing gradient gel electrophoresis combined with sequencing analysis revealed that earthworms pronouncedly modified bacterial and fungal community structures, through broadening the community diversities of Actinobacteria, Bacteroidetes, Proteobacteria, and Ascomycotina. These results suggest that the presence of earthworms promoted the activity and population of bacteria and fungi, and modified their communities, thus altering the decomposition pathway of fresh FVW.

    The Fresh Kids programme utilized the Health Promoting Schools (HPSs) framework to design a whole-of-school, multifaceted intervention targeting specific behaviours to promote healthy eating and reduce the risk factors associated with childhood obesity. The aim of the programme was to evaluate the effectiveness of the HPS framework to increase fruit and water consumption among primary school-aged children over a 2-year period. The study design was an interrupted time series. Four primary schools in the inner west of Melbourne, Australia, participated in the programme intervention. Baseline data were collected using a lunch box audit to assess the frequency of children with fresh fruit, water and sweet drinks, either brought from home or selected from canteen lunch orders. The lunch box audit was repeated periodically for up to 2 years following programme implementation to assess the sustainability of dietary changes. Across all participating schools, significant increases between 25 and 50% were observed in the proportion of children bringing fresh fruit. Similarly, all schools recorded increases between 15 and 60% in the proportion of students bringing filled water bottles to school and reductions between 8 and 38% in the proportion of children bringing sweet drinks. These significant changes in dietary patterns were sustained for up to 2 years following programme implementation. Targeting key nutrition behaviours and using the HPS framework is an effective and simple approach which could be readily implemented in similar childhood settings. Effective strategies include facilitating organizational change within the school; integrating curriculum activities; formalizing school policy and establishing project partnerships with local community nutrition and dietetic services.

Cam.), and acerola (Malpighia glaba L) was verified. The incidence of proteolytic, pectinolytic, and mycocinogenic yeasts on these communities was also determined. A total of 480 colonies was isolated and grouped in 405 different strains. These corresponded to 42 ascomycetous and 28 basidiomycetous species. Candida sorbosivorans, Pseudozyma antarctica, C. spandovensis-like, C. spandovensis, Kloeckera apis, C. parapsilosis, Rhodotorula graminis, Kluyveromyces marxianus, Cryptococcus laurentii, Metchnikowia sp (isolated only from pitanga ripe fruits), Issatchenkia occidentalis and C. krusei (isolated only from mangaba frozen pulps), were the most frequent species. The yeast communities from pitanga ripe fruits exhibited the highest frequency of species, followed by communities from acerola ripe fruits and mangaba frozen pulps. Yeast communities from frozen pulp and ripe fruits of umbu had the lowest number of species. Except the yeasts from pitanga, yeast communities from frozen pulp exhibited higher number of yeasts than ripe fruit communities. Mycocinogenic yeasts were found in all of the substrates studied except in communities from umbu ripe fruits and pitanga frozen pulps. Most of the yeasts found to produce mycocins were basidiomycetes and included P. antarctica, Cryptococcus albidus, C. bhutanensis-like, R. graminis and R. mucilaginosa-like from pitanga ripe fruits as well as black yeasts from pitanga and acerola ripe fruits. The umbu frozen pulps community had the highest frequency of proteolytic species. Yeasts able to hydrolyse casein at pH 5.0 represented 38.5% of the species isolated. Thirty-seven percent of yeast isolates were able to hydrolyse casein at pH 7.0. Pectinolytic yeasts were found in all of the communities studied, excepted for those of umbu frozen pulps. The highest frequency of

    Full Text Available Abstract Background Little is known about how affordability of healthy food varies with community characteristics in rural settings. We examined how the cost of fresh fruit and vegetables varies with the economic and demographic characteristics in six rural counties of Texas. Methods Ground-truthed data from the Brazos Valley Food Environment Project were used to identify all food stores in the rural region and the availability and lowest price of fresh whole fruit and vegetables in the food stores. Socioeconomic characteristics were extracted from the 2000 U.S. Census Summary Files 3 at the level of the census block group. We used an imputation strategy to calculate two types of price indices for both fresh fruit and fresh vegetables: a high variety and a basic index; and evaluated the relationship between neighborhood economic and demographic characteristics and affordability of fresh produce, using linear regression models. Results The mean cost of meeting the USDA recommendation of fruit consumption from a high variety basket of fruit types in our sample of stores was just over $27.50 per week. Relying on the three most common fruits lowered the weekly expense to under $17.25 per week, a reduction of 37.6%. The effect of moving from a high variety to a low variety basket was much less when considering vegetable consumption: a 4.3% decline from $29.23 to $27.97 per week. Univariate regression analysis revealed that the cost of fresh produce is not associated with the racial/ethnic composition of the local community. However, multivariate regression showed that holding median income constant, stores in neighborhoods with higher percentages of Black residents paid more for fresh fruits and vegetables. The proportion of Hispanic residents was not associated with cost in either the univariate or multivariate analysis. Conclusion This study extends prior work by examining the affordability of fresh fruit and vegetables from food stores in a large

    Tomato production in Ghana is characterized by a glut and high post - harvest losses during the major season followed by scarcity and high prices during the off season. This is the result of the absence of a standard method for preservation of fresh fruits. This research was conducted to determine an effective method for the post - harvest treatment of fresh tomato fruits to enhance shelf life while preserving its physiochemical and nutritional properties. Two experiments were conducted, each with a factorial design of 5x2. In experiment one, the fruits were subjected to 0,1,2,3,and 4 kGy gamma radiation and stored at 10±1°C and 28±1°C. In experiment two, CaCl 2 dissolved in distilled water at 0, 1.00, 1.50, 2.00 and 2.50% concerntrations were used to coat tomato fruits and stored at 10±1°C and 28±1°C. Gamma radiation at 4kGy extended the shelf life of tomato by 5 and 9 days above control when stored at 28±1°C and 10±1°C respectively. The use of CaCl 2 at 2.5% greatly extended the shelf life of tomato by 11days and 18 days above control when stored at 28±1°C and 10±1°C respectively. For both treatments, shelf life increased with increasing dose of radiation/ concentraionn of CaCl 2 . Weight loss was higher in control fruits as well as fruits treated with gamma radiation or CaCl 2 coating stored at 28±1°C temperature than treated fruits stored at 10±1°C. Tomato fruits treated with gamma radiation at 1 and 2 kGy and untreated fruits showed an increased in pH and Total Soluble Solids (TSS) which was paralleled by a decrease in Total Titratable Acidity (TTA) as storage period advance at both storage temperatures. However, fruits treated with CaCl 2 at 1.00% had little effect on pH and TTA of tomato during the storage period. Nutritionally, CaCl 2 coating significantly maintained the vitamin C and Iycopene concentrations in tomato fruit more than control and gamma irradiation which reduced vitamin C and Iycopene contents in the fruits significantly

    A set of onomatopoeic expressions for eating fruits and vegetables is compared across subjects whose native language is Spanish, French, or German. Subjects chose the onomatopoeia that best represented the sound of eating a fruit or vegetable (celery, banana, strawberry, passion fruit, mango, apple, orange, and tomato). Results show there are onomatopoeias that have a higher frequency of response in one language compared to the others. Thus, it is possible to assume that depending on the language there is a better way to express haptic and auditory information associated to fruit and vegetable consumption. Moreover, and considering the three languages, results show there are three categories of responses based on the relative strength of the material (strong and medium strength, and soft). Thus, there is some consistency in the onomatopoeias that represent the sound of eating a fruit or a vegetable. To conclude, results differ by language, but they are consistent within a category of sound. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Argentina produces 1.8 million tons/year of apples ( Malus domestica L.) and pears ( Pyrus communis L.) in the Patagonia region. Cydia pomonella, codling moth, and Grapholita molesta, Oriental fruit moth, ( Lepidoptera: Tortricidae) are quarantine pests in pome fruits. Irradiation is a promising phytosanitary treatment because a dose of 200 Gy completely prevents pest adult emergence. A pilot irradiation process of commercially packaged 'Red Delicious' apples and 'Packham's Triumph' pears was performed in an irradiation facility with a Cobalt 60 source. Quality analyses were carried out at 0, 2, 4, 6 and 8 months of storage (1 °C, RH 99%) to evaluate fruit tolerance at 200, 400 and 800 Gy. Irradiation at 200 and 400 Gy had no undesirable effects on fruit quality (pulp firmness, external colour, soluble solids content (SSC), titratable acidity (TA) and sensory evaluations). Irradiation of 'Red Delicious' apples and 'Packham's Triumph' pears can be applied as a commercial quarantine treatment with a minimum absorbed dose of 200 Gy (to control codling moth and Oriental fruit moth) and <800 Gy (according to quality results).

    Some countries already permit the irradiation of foods to extend its storage life and to control pests, therefore, a faster and significantly more uniform identification method are needed. Half-embryo test is based on the inhibition of shooting due to gamma irradiation since biological systems are sensitive to low doses of gamma irradiation. The intact fruits, apples, lemons, oranges and watermelons were obtained from the local market and irradiated directly with doses of 0.5, 0.75, 1.5 and 3 KGy. Shooting was defined as the elongation of the shoot to the extent of at least 1 mm length in apples and watermelon, while 0.5 mm length in citrus fruits. Root and shoot growth was stimulated most strongly by the addition of benzyladenine (2.5 mg/l) as a growth hormone. Shooting started after 1-3 days and reached to 90 % after 4 days. A long lasting half-embryo test (4-5 days) was capable to discriminate between irradiated and non-irradiated fruits. Growth of half-embryo and the changes were almost the same in all non-irradiated fruits under study. Growth of half-embryo irradiated with a dose of 0.5 KGy or more almost has totally retarded elongation of both root and shoot. Practically, it was observed that small-developed shoots showed slight elongation and afterward they were decayed. If shooting percentage after 1-3 days is less than 20% in apples, 40% in oranges and 30% in lemons and watermelons, the fruits are classified as i rradiated u nder 0.5 KGy as a detection limit dose of the irradiation. Irradiation caused obvious changes in root and shoot growth of half-embryos studied. Roots of non-irradiated half-embryos grew well in all fruits under study and those irradiated with 0.5 KGy or more were obviously reduced. In the same way, shoots of non-irradiated half-embryo grew well and shooting percentage reached to 50 % after 1-2 days and those fruits irradiated with 0.5 KGy or more were reduced. It is recommended to employ the half-embryo test as a practical technique

    Echinococcus multilocularis is a tapeworm that may cause alveolar echinococcosis (AE), one of the most dangerous parasitic zoonoses. As in the case of other foodborne diseases, unwashed fruits and vegetables, contaminated with dispersed forms of E. multilocularis, may serve as an important transmission route for this parasite. In this article, we reply to the incorrect interpretation of results of our study concerning the detection of E. multilocularis DNA in fresh fruit, vegetable and mushroom samples collected from the highly endemic areas of the Warmia-Masuria Province, Poland, to dispel any doubts. The accusations formulated by the commentators concerning our paper are unfounded; moreover, these commentators demand information which was beyond the purview of our study. Making generalisations and drawing far-reaching conclusions from our work is also unjustified. The majority of positive samples were found in only a few hyperendemic communities; this information corresponds with the highest number of both infected foxes and AE cases in humans recorded in this area. Our findings indicate that E. multilocularis is present in the environment and may create a potential risk for the inhabitants. These people should simply be informed to wash fruits and vegetables before eating. No additional far-reaching conclusions should be drawn from our data. We believe these commentators needlessly misinterpreted our results and disseminated misleading information. Nevertheless, we would like to encourage any readers simply to contact us if any aspects of our study are unclear.

    The activity of lowering fresh fruit bunches (FFB) from truck to sorting floor is performed manually by workers using a sorting tool. Previously, the sorting tool used is a pointed iron bar with a T-shaped handle. Changes made to the sorting tool causes several complaints on worker and affect the time to lower the fruit. The purpose of this article is to obtain the design of an FFB sorting tool that suits the needs of these workers by applying the Quality Function Deployment (QFD) and Kano Model methods. Both of the two methods will be integrated to find the design that matches workers’ image and psychological feeling. The main parameters are to obtain the customer requirements of the palm fruit loading workers, to find the most important technical characteristics and critical part affecting the quality of the FFB sorting tool. The customer requirements of the palm loading workers are the following : the color of the coating paint is gray, the bar material is made of stainless pipe, the main grip coating material is made of grip, the tip material is made of the spring steel, the additional grip is made of rubber and the handle is of triangular shape.

    The decline in bio generating capacity to form natural antibiotic compounds (phytoalexins), rishitin and lubimin in potato tubers and rishitin in tomatoes, after gamma irradiation seems to be the essence of the suppression of natural immunity exhibited by an increase in per cent of rotted tubers and fruits during storage. In vitro studies postulated that the rot-causing fungi Phytophthora infestons (Mond) De Bary, Alternaria solani (Ellis and Martin) James and Grout, Botrytis cinerea Persson., Fusarium oxysporum Syder and Hansen and Rhizopus stolonifer Ehrenberg were significantly controlled by the application of phytoalexins that had been initially formed by potato tubers (rishitin), tomato fruits (rishitin) and pepper fruits (capsidiol). In vivo studies revealed that post-irradiation treatment of potato tubers and tomato fruits with phytoalexins that had been produced by the same plant organ or by another of the same family seems to be experimentally feasible to reduce the radiation dose or increase the efficiency of irradiation in controlling microbial spoilage during storage of irradiated potatoes and tomatoes.

    There were performed preliminary electron-beam irradiation of strawberries, cherries, and sour cherries. The irradiations were carried out with the IPTRD's electron acceleration at 6 MeV, at different dose-rates, particularly at 1-3 kGy for strawberries, and 0.5-2.0 kGy for cherries. The dosimetry was performed using a PTW medical dosemeter. After irradiation the samples were controlled and preserved at 8-10 o C, 75-85% r.h. The fruits were then analysed for organoleptic and nutritional preservation characteristics , sugars, acidity, C-vitamin, etc. They were also examined in order to find criteria for identification of irradiated fruits. The results show a good shelf-life extension for 5-15 days and the suggest the capability of using the electron-beam irradiation technologies in agro-food industry. (Author)

    CM-chitosan was irradiated with various doses in powder state and solution using Co 60 gamma source. The changes of viscosity in solution as well as molecular weight were also measured. The molecular weight reduced with increasing of radiation dose. The antimicrobial activity of CM-chitosan and irradiated CM-chitosan in solution against E.coli was investigated. In this studies, the sensitivity of E.coli depended on the concentration of CM-chitosan supplemented into medium and the antimicrobial activity of irradiated CM-chitosan was found to increase with radiation dose and reached to maximum with dose of 100 kGy. The 2% aqueous solutions prepared from CM-chitosan and 100 kGy irradiated CM-chitosan as mentioned above were applied for apple preservation. All coating fruits have significantly reduced the weight loss, spoilage ratio compared with control. Chemical and sensory quality of coated fruits were evaluated and compared, the best results were achieved with fruit coated using irradiated CM-chitosan. (author)

    Organic acids are known to be used as food preservatives due to their antimicrobial potential. This study evaluated the ability of three organic acids, namely, acetic acid, citric acid and lactic acid to manage E. coli and Salmonella sp. from fresh fruits and vegetables. Effect of these organic acids on biofilm forming ability and anti-quorum potential was also investigated. The effect of organic acids on inactivation of E. coli and Salmonella sp. on the surface of a selected vegetable (cucumber) was determined. The minimum inhibitory concentration of the organic acids were found to be 1.5, 2 and 0.2% in E. coli while it was observed to be 1, 1.5 and 1% in Salmonella sp. for acetic, citric and lactic acids respectively. Maximum inhibition of biofilm formation was recorded at 39.13% with lactic acid in E. coli and a minimum of 22.53% with citric acid in Salmonella sp. EPS production was affected in E. coli with lactic acid showing reduction by 13.42% while citric acid and acetic acid exhibited only 6.25% and 10.89% respectively. Swimming and swarming patterns in E. coli was notably affected by both acetic and lactic acids. Lactic and acetic acids showed higher anti-quorum sensing (QS) potential when compared to citric acid. 2% lactic acid showed a maximum inhibition of violacein production by 37.7%. Organic acids can therefore be used as potential quorum quenching agents in food industry. 2% lactic acid treatment on cucumber demonstrated that it was effective in inactivating E. coli and Salmonella sp. There was 1 log reduction in microbial count over a period of 6 days after the lactic acid treatment. Thus, organic acids can act as effective potential sanitizers in reducing the microbial load associated with fresh fruits and vegetables. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available This paper traces the growth of the new retail formats such as hypermarkets, departmental stores and supermarkets and its implications to the fruits and vegetables sector in Malaysia in particular to the small producers. The structural differences between the new supply chain and conventional marketing are compared. Some measures of concentration are provided to indicate the degree of competition in the retail sector. Within less than a decade, the new super retailers were able to capture a significant market share of the local fruits and vegetables at the expense of the small time local retailers. Their procurement system which emphasizes on consistent supply and rigid quality standards indirectly cuts off the small farmers from the supply chain. New type of intermediaries, packing houses emerge replacing the traditional middlemen role usually performed by small time wholesalers or traders at the farm level. To integrate the small farmers into the new supply entails a reformation programme that enhances productivity, product quality and institutional restructuring towards cooperative movement.

  17. Cancer-Related Constituents of Strawberry Jam as Compared with Fresh Fruit

    2016-01-01

    Full Text Available The health awareness recently shown by consumers has led to a demand for health beneficial products. In particular, researchers are currently focusing their studies on the search for foods for cancer prevention activity. In the present work, we study comparatively the effect of two different processing methods on the contents of phenolic compounds (i.e., ellagic acid, myricetin, quercetin and kaempferol with antioxidant and antitumor properties in strawberry jams. In turn, the results obtained were compared with those of unprocessed fruit. Additionally carcinogenic heat-induced compounds formed by the two jam making methods were evaluated. Decreases of total ellagic acid from 138.4 µg/g to 86.5 µg/g were measured in jam as compared with the intact fruit. Even higher losses of up to 90% of total flavonols were found in strawberry after the jam-making process. A comparison between the two processing methods proved shorter heating periods (around 60 min even at temperatures as high as 100 °C enabled losses of antioxidant phenolics to be minimized. Carcinogenic heat-induced volatile compounds, mainly Maillard reaction products, were formed as a result of thermal treatment during jam processing. However, shorter heating periods also helped reduce the formation of these harmful compounds. These results are deeply discussed. From a practical standpoint, the processing conditions here proposed can be used by industry to obtain strawberry jam with higher content of antioxidant flavonoids and, at the same time, reduced amounts of carcinogenic compounds.

    Full Text Available Important component of the tomato are carotenoid dyes, especially lycopene. The importance of lycopene in the diet of people in recent years has grown mainly for its pharmacological effects due to its ability to reduce the risk of carcinoma diseases and prevention of cardiovascular diseases. The aim of this work was to analyze the content of total carotenoids and lycopene in 8 varieties of tomato and to monitor dynamic changes after their different treatments (heating, drying. The experiment included following tomato varieties: Bambino F1, Darina F1, Diana F1, Denár, Milica F1, Orange F1, Paulína F1, Šejk F1.We found that processing of tomato fruits into juices and dried slices positively affected the presence of carotenoids and lycopene. Processing leads to an increase in the content of carotenoids that can be attributed to better availability of these components in the human body.

    2008-01-01

    During the time of the Wilhelmine Empire, there were multiple interdependencies between adherents of the life reform movement (vegetarians, naturopathists, nudists, etc.) and new religious movements such as esoteric groups like the theosophists in the alternative cultural milieu around 1900. These networks became visible in the form of double memberships in associations. However, there were also ambiguous affiliations, migration between groups and syncretistic beliefs without institutional belonging. The similarity between patterns of argumentation for this specific lifestyle and the congruence of chosen goals, ways and goods of salvation become particularly clear in this context. These forms of "methodical lifestyle" may lead to the development of a specific ethos or habitus (Max Weber). To illustrate these processes, this article analyses the report of a Leipzig lady who ate raw fruits and vegetables only, and examines her broader social context. Thereby the analysis will employ sociological theories of conversion to explain the case of Hedwig Bresch.

    2003-03-01

    The effects of gamma radiation on codling moth eggs and mature larvae from the Syrian strain and on apple fruit from the Starking variety grown in the southern part of Syria was evaluated. Results showed that egg sensitivity to gamma radiation decreased with the age of the larvae when irradiated and reached its minimum in eggs irradiated shortly before egg hatch. At this stage, a dose of 350 Gy was required to reduce egg batch to less than 30%. The effect of gamma radiation was more clear, however, when adult emergence was used as a criterion for measuring effectiveness. For instance, exposing eggs in the black head stage (hours before hatch) to a dose of 40 Gy reduced adult emergence to about 22% and a dose of 60 Gy prevented it completely. The results of studying effects of gamma radiation on mature larvae showed that diapausing larvae were more sensitive to irradiation than non-diapausing ones and females were more sensitive than males. It also showed that a dose of 200 Gy prevented adult emergence in more than one hundred thousand fifth in star larvae irradiated in apples. Studying the effects of gamma radiation on apples grown in the southern part of Syria showed that a dose of 400 Gy had a slight effect on weight lose in the first six weeks of storage and that doses higher than 200 Gy caused a slight decrease in apple firmness, particularly, after 90 days of storage. In summery, the study indicates that the use of ionizing radiation as a quarantine treatment for codling moth infested fruit is possible and requires relatively low dose. In such a process, prevention of moth emergence should be used as a criterion for effectiveness and a dose of no more than 200 Gy is sufficient. (author)

    Full Text Available Objective: To establish the health benefits of Syzgium cumin to discover functional components present in the seeds, fruit pulps and fresh juice of this fruit grown in Bangladesh. Methods: Thin layer chromatography and ultra-violet spectroscopy were used to detect the presence of various types of compound in seeds and juice. Antioxidant effects were measured by DPPH scavenging assay and total reducing assay. Receptor binding activities was performed by hemagglutination inhibition assay. Anti-inflammatory assay and hydrogen peroxide induced hemolysis assay was also investigated. Disc diffusion assay was performed to show the antibacterial effect using Gram positive, Gram negative strains of bacteria and fungi. Results: Methanolic extract of the seeds showed stronger antioxidant, hydrogen peroxide induced hemolysis activities, hemagglutination inhibition activities and membrane stabilization activities than those of fresh juice. However, fresh juice showed stronger antibacterial and antifungal activities than those of methanolic seed extract. The seed contains higher amount of polyphenols and flavanoids than those of fruit juice. Conclusions: Therefore, fruit juice, fruit pulp and seed of Syzygium cumini contain medicinal active components in different ratios.

    Full Text Available Novel methodology is presented for indexing the relative potential of hosts to function as resources. A Host Potential Index (HPI was developed as a practical framework to express relative host potential based on combining results from one or more independent studies, such as those examining host selection, utilization, and physiological development of the organism resourcing the host. Several aspects of the HPI are addressed including: 1 model derivation; 2 influence of experimental design on establishing host rankings for a study type (no choice, two-choice, and multiple-choice; and, 3 variable selection and weighting associated with combining multiple studies. To demonstrate application of the HPI, results from the interactions of spotted wing drosophila (SWD, Drosophila suzukii Matsumura (Diptera: Drosophilidae, with seven "reported" hosts (blackberries, blueberries, sweet cherries, table grapes, peaches, raspberries, and strawberries in a postharvest scenario were analyzed. Four aspects of SWD-host interaction were examined: attraction to host volatiles; population-level oviposition performance; individual-level oviposition performance; and key developmental factors. Application of HPI methodology indicated that raspberries ( (meanHPIvaried  = 301.9±8.39; rank 1 of 7 have the greatest potential to serve as a postharvest host for SWD relative to the other fruit hosts, with grapes ( (meanHPIvaried  = 232.4±3.21; rank 7 of 7 having the least potential.

    Microbial and aroma attributes are within the most decisive factors limiting safety and sensory appealing of fresh-cut fruits and vegetables. Alternatively, several plant essential oils (EOs) are constituted of several volatile active compounds and most of them present antimicrobial potential and had different aroma profile. Considering these premises, this hypothesis article states that safety and aroma appealing of fresh-cut produce could be improved with EO treatment. EOs could prevent fresh-cut fruit decay; however, their volatile constituents could be sorbed by the produce, and according to the aroma notes of the antimicrobial oil, sensorial appealing of odor, and flavor of the treated produce might be affected positively or negatively. Specifically, garlic oil is a natural antimicrobial constituted by sulfur compounds, which are responsible for its odor and antimicrobial properties. Besides, fresh-cut tomato is a highly perishable product that needs antimicrobial agents to preserve its quality and safety for a longer period of time. From the sensorial point of view, aroma combination of garlic and tomato is a common seasoning practice in Europe and America and well accepted by consumers. Once the right combination of flavors between the EOs and the fresh-cut produce has been selected, safety and quality of the treated fruit could be improved by adding antimicrobial protection and extra aroma. Therefore, other combinations between EOs and fresh-cut produce are discussed. This approximation could reinforce the trends of natural food preservation, accomplishing the demands of the increasing sector of consumers demanding tasty and convenient fresh-cut produce, containing only natural ingredients.

    The effects of fluorescent light on the availability of selected antioxidant compounds and antioxidant activity during storage of fresh-cut carambola (Averrhoa carambola L.) fruit were investigated. The samples of fresh-cut fruit, stored at 5 +- 1 deg. C, were exposed to fluorescent light (157 Lux) for 12 days. Total phenolic compounds (TPC) and ascorbic acid (AA) content of the processed fruit were analyzed using Folin-Ciocalteu reagent and high performance liquid chromatography (HPLC), respectively. Antioxidant activity of the fruit was assessed following 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging capacity and ferric-reducing antioxidant power (FRAP) assays. The results of the present study showed that light exposure did not exert any significant effect, while storage period significantly reduced the AA content of the fruits tested. On the other hand, with few exceptions, there were notable random changes, recorded in the TPC and antioxidant activity of the fruit as function of storage period and light exposure. (author)

    Piper guineense Schum & Thonn (Piperaceae) is a medicinal plant used in the Southern States of Nigeria to treat fever, mental disorders and febrile convulsions. This study aims at determining the chemical composition and the central nervous system (CNS) activities of the essential oil obtained from the plant׳s fresh fruits in order to rationalize its folkloric use. Essential oil of P. guineense (EOPG) obtained by hydrodistillation was analysed by GC/MS. EOPG (50-200mg/kg, i.p.) was evaluated for behavioural, hypothermic, sedative, muscle relaxant, anti-psychotic and anticonvulsant activities using standard procedures. Analysis of the oil reveals 44 compounds of which 30 compounds constituting 84.7% were identified. The oil was characterized by sesquiterpenoids (64.4%) while only four monoterpeneoids (21.3%) were found present in the oil. Major compounds identified were β-sesquiphellandrene (20.9%), linalool (6.1%), limonene (5.8%), Z-β-bisabolene (5.4%) and α-pinene (5.3%). The EOPG (50-200mg/kg, i.p.) caused significant (p<0.01) inhibition on rearing {F(4,20)=43}, locomotor {F(4,20)=22} activity and decreased head dips in hole board {F(4,20)=7} indicating CNS depressant effect; decreased rectal temperature {F(4,20)=7-16}, signifying hypothermic activity; decreased ketamine-induced sleep latency {F(4,20)=7.8} and prolonged total sleeping time {F(4,20)=8.8}, indicating sedative effect; reduced muscular tone on the hind-limb grip test {F(4,20)=22}, inclined board {F(4,20)=4-49} and rota rod {F(4,20)=13-106}, implying muscle relaxant activity; induced catalepsy {F(4,20)=47-136}, inhibited apomorphine-induced climbing behaviour {F(4,20)=9} and inhibited apomorphine-induced locomotor {F(4,20)=16}, suggesting anti-psychotic effect; and protected mice against pentylenetetrazole-induced convulsions, indicating anticonvulsant potential. The most abundant component of the fresh fruits essential oil of P. guineense was β-sesquiphellandrene (20.9%); and the oil possesses

    Food waste is a problem with economic, environmental and social implications, making it both important and complex. Previous studies have addressed food waste management options at the less prioritised end of the waste hierarchy, but information on more prioritised levels is also needed when selecting the best available waste management options. Investigating the global warming potential and primary energy use of different waste management options offers a limited perspective, but is still important for validating impacts from the waste hierarchy in a local context. This study compared the effect on greenhouse gas emissions and primary energy use of different food waste management scenarios in the city of Växjö, Sweden. A life cycle assessment was performed for four waste management scenarios (incineration, anaerobic digestion, conversion and donation), using five food products (bananas, tomatoes, apples, oranges and sweet peppers) from the fresh fruit and vegetables department in two supermarkets as examples when treated as individual waste streams. For all five waste streams, the established waste hierarchy was a useful tool for prioritising the various options, since the re-use options (conversion and donation) reduced the greenhouse gas emissions and the primary energy use to a significantly higher degree than the energy recovery options (incineration and anaerobic digestion). The substitution of other products and services had a major impact on the results in all scenarios. Re-use scenarios where food was replaced therefore had much higher potential to reduce environmental impact than the energy recovery scenarios where fossil fuel was replaced. This is due to the high level of resources needed to produce food compared with production of fossil fuels, but also to fresh fruit and vegetables having a high water content, making them inefficient as energy carriers. Waste valorisation measures should therefore focus on directing each type of food to the waste

    Investigations were carried out on standardization of desired process control parameters such as dose distribution in trade containers, container standardization and development of 'label' dosimeters. A prototype 'label' dose indicators Sterins for threshold doses of 125 Gy and 300 Gy was studied. Dose distribution was studied using fresh fruits and tree nuts in trade and standardized containers with varying product densities. The distribution of absorbed doses was measured by Fricke, Gammachrome YR, clear Polymethylmethacrylate (PMMA), EthanolChlorobenzene (ECB) and Sterin 300. These values are given as Dmax/Dmin ratios in relation to product bulk densities. It was observed that bulk densities varied greatly among different products depending on the types of fruits, containers and pattern of loading which also affected dose distribution. Dmax/Dmin obtained by proper dose mapping could be kept low by arranging proper irradiation conditions which ensured uniform dose distribution. Prototype 'label' dose indicators like Sterins and clear PMMA were used for dose mapping along with the standard primary and secondary dosimeters. Sterins and clear PMMA were also studied for their dosimetric properties, particularly for use in label dosimetry. Sterins 125 and 300 evaluated visually showed their integrity at their threshold doses. The word NOT on Sterin 125 eclipsed after 115 Gy and on Sterin 300 after 270 Gy dose. Clear PMMA samples of 410 mm thickness irradiated at 200-1000 Gy showed linear response and had postirradiation stability for over a month storage at normal temperatures (21-35 deg. C) and humidities. These could be investigated further for developing as 'label' dosimeters in insect control quarantine treatment. Other low dose indicators studied such as coloured perspex, dye solutions were not found useful at quarantine dose levels. Further investigations are required for developing a 'label' dosimeter for commercial use. (author)

    A consumer survey was organized in Spain and Belgium to obtain consumption data and to gain insight into consumer handling practices for fresh vegetables consumed raw or minimally processed (i.e., heads of leafy greens, bell peppers, tomatoes, fresh herbs, and precut and packed leafy greens) and fruits to be consumed without peeling (i.e., apples, grapes, strawberries, raspberries, other berries, fresh juices, and precut mixed fruit). This information can be used for microbiological and/or chemical food safety research. After extensive cleanup of rough databases for missing and extreme values and age correction, information from 583 respondents from Spain and 1,605 respondents from Belgium (18 to 65 years of age) was retained. Daily intake (grams per day) was calculated taking into account frequency and seasonality of consumption, and distributions were obtained that can be used in quantitative risk assessment for chemical hazards with chronic effects on human health. Data also were recalculated to obtain discrete distributions of consumption per portion and the corresponding frequency of consumption, which can be used in acute microbiological risk assessment or outbreak investigations. The ranked median daily consumption of fruits and vegetables was similar in Spain and Belgium: apple > strawberry > grapes > strawberries and raspberries; and tomatoes > leafy greens > bell peppers > fresh herbs. However, vegetable consumption was higher (in terms of both portion and frequency of consumption) in Spain than in Belgium, whereas the opposite was found for fruit consumption. Regarding consumer handling practices related to storage time and method, Belgian consumers less frequently stored their fresh produce in a refrigerator and did so for shorter times compared with Spanish consumers. Washing practices for lettuce heads and packed leafy greens also were different. The survey revealed differences between these two countries in consumption and consumer handling practices

    Manufacturers engaged in the business, producing CPO and kernels whose raw materials are oil palm fresh fruit bunches taken from their own plantation, generally face problems of transporting from plantation to factory where there is often a change of distance traveled by the truck the carrier of FFB is due to non-specific transport instructions. The research was conducted to determine the optimal transportation route in terms of distance, time and route number. The determination of this transportation route is solved using Nearest Neighbours and Clarke & Wright Savings methods. Based on the calculations performed then found in area I with method Nearest Neighbours has a distance of 200.78 Km while Clarke & Wright Savings as with a result of 214.09 Km. As for the harvest area, II obtained results with Nearest Neighbours method of 264.37 Km and Clarke & Wright Savings method with a total distance of 264.33 Km. Based on the calculation of the time to do all the activities of transporting FFB juxtaposed with the work time of the driver got the reduction of conveyance from 8 units to 5 units. There is also improvement of fuel efficiency by 0.8%.

    Full Text Available ABSTRACT Despite the increasing reports on the incidence of fresh vegetables and fruits as a possible vehicle for human pathogens, there is currently limited knowledge on the growth potential of Escherichia coli O157:H7 on different plant substrates. This study analyzed the selective adhesion and growth of E. coli O157:H7 on chili habanero (Capsicum chinense L., cucumber (Cucumis sativus, radish (Raphanus sativus, tomato (Lycopersicon esculentum, beet (Beta vulgaris subsp. vulgaris, and onion (Allium cepa L. under laboratory conditions. The Gompertz parameters were used to determine the growth kinetics. Scanning electron microscopy was used to visualize the adhesion of E. coli O157:H7 on the epicarp of the samples. Predictive models were constructed to compare the growth of E. coli O157:H7 on the samples with different intrinsic factors and to demonstrate the low selectivity of the pathogen. No significant difference was observed in the lag-phase duration (LPD, generation time (GT, and exponential growth rate (EGR of the pathogen adhered to the samples. The interaction between the microorganism and the substrate was less supportive to the growth of E. coli O157:H7 for onion, whereas for tomato and cucumber, the time for the microorganism to attain the maximum growth rate (M was significantly longer than that recorded for other samples.

    Data presented in this paper reflect changes in antioxidant activity, the content of prooxidant factors and deuterium concentration in freshly squeezed juices from fruits and vegetables grown in different climatic regions (10 samples of juices from wholesale and retail trade network of 8 kinds of vegetables and fruits, 28 manufacturers from 14 countries). Determination of the concentration of deuterium was performed using a nuclear magnetic resonance spectrometer. Total antioxidant activity of fresh juices was determined amperometrically after dilution in 2.2 mM H3PO4 in a ratio of 1:100. Prooxidant performance was evaluated by a maximum and area of flash of chemiluminescence induced by the introduction of 0.3% hydrogen peroxide. It was found that the antioxidant activity of fresh juice from fruits and vegetables grown within the same climatic region can differ by several times. In this case, most of the fruits and vegetables of russian producers were not inferior, than antioxidant activity of the fresh juices from the same plant products grown abroad. It should be noted that the indicators of the antioxidant activity of fresh juice from Russian pears exceeded this indicator of all fresh juices from pears, imported from Argentina, South Africa and the United States of America by 21.1, 30.4 and 32.7%, respectively. In assessing the prooxidant properties of fresh juices should be noted the almost complete absence of factors with prooxidant nature only in 36% of the studied fresh juices, whose maximum performance and area of flash of chemiluminescence were less than 0.1%, including a pear and apple juices from the russian production. It should be noted that the area of chemiluminescence of the juice from potatoes, grown in Russia, was at 103.1 and 115.2% lower than in juice obtained respectively from potatoes produced in Israel and Egypt (pcomposition of fresh juices it was found that the highest deuterium content was in the juice from the pears, imported from

    Food deserts, areas that lack full-service grocery stores, may contribute to rising rates of obesity and chronic diseases among low-income and racial/ethnic minority residents. Our corner store project, part of the Centers for Disease Control and Prevention's Communities Putting Prevention to Work initiative, aimed to increase availability of healthful foods in food deserts in Nashville, Tennessee. We identified 4 food deserts in which most residents are low-income and racially and ethnically diverse. Our objectives were to develop an approach to increase availability of fresh fruits and vegetables, low-fat or nonfat milk, and 100% whole-wheat bread in Nashville's food deserts and to engage community members to inform our strategy. Five corner stores located in food deserts met inclusion criteria for our intervention. We then conducted community listening sessions, proprietor surveys, store audits, and customer-intercept surveys to identify needs, challenges to retailing the products, and potential intervention strategies. Few stores offered fresh fruits, fresh vegetables, low-fat or nonfat milk, or 100% whole-wheat bread, and none stocked items from all 4 categories. Major barriers to retailing healthful options identified by community members are mistrust of store owners, history of poor-quality produce, and limited familiarity with healthful options. Store owners identified neighborhood crime as the major barrier. We used community input to develop strategies. Engaging community residents and understanding neighborhood context is critical to developing strategies that increase access to healthful foods in corner stores.

    This hypothesis article states that the high relative humidity (RH) of packaged fresh-cut fruits or vegetables that is associated with spoilage can be used as an advantageous way to deliver antimicrobial compounds using cyclodextrins (CDs) as carriers. CDs can function as antimicrobial delivery systems as they can release antioxidant and antimicrobial compounds (guest molecules) as the humidity levels increase in the headspace. Hydrophobic antimicrobial guests can be complexed with CDs due to the amphiphatic nature of the host. Then, at high RH values, due to the water-CDs interaction, host-guest interactions are weakened; consequently, the antimicrobial molecule is released and should protect the product against the microbial growth. Potential antimicrobial compounds capable of forming complexes with CDs are discussed, as well as possible applications to preserve fresh-cut produce and future research in this area.

    This study evaluated the feasibility of obtaining methane in anaerobic digestion (AD) from the waste products generated by the processing of fruit and vegetables. During the first phase (0-55 d) of the AD using sludge from fruit and vegetable processing, an average value of 244±88 L kg(-1) dry matter d(-1)of biogas production was obtained, and methane content reached 65% of the biogas. Co-digestion with chopped fresh artichoke wastes in a second phase (55-71 d) enhanced biogas production, and resulted in an average value of 354±68 L kg(-1) dry matter d(-1), with higher methane content (more than 70%). The archaeal community involved in methane production was studied using the ANAEROCHIP microarray and real-time PCR. Results indicated that species of Methanosaeta and Methanosarcina were important during the AD process. Methanosarcina numbers increased after the addition of chopped fresh artichoke, while Methanosaeta numbers decreased. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available From the Malaysian harvester’s perspective, the determination of the ripeness of the oil palm (FFB is a critical factor to maximize palm oil production. A preliminary study of a novel oil palm fruit sensor to detect the maturity of oil palm fruit bunches is presented. To optimize the functionality of the sensor, the frequency characteristics of air coils of various diameters are investigated to determine their inductance and resonant characteristics. Sixteen samples from two categories, namely ripe oil palm fruitlets and unripe oil palm fruitlets, are tested from 100 Hz up to 100 MHz frequency. The results showed the inductance and resonant characteristics of the air coil sensors display significant changes among the samples of each category. The investigations on the frequency characteristics of the sensor air coils are studied to observe the effect of variations in the coil diameter. The effect of coil diameter yields a significant 0.02643 MHz difference between unripe samples to air and 0.01084 MHz for ripe samples to air.

    Full Text Available Organic agriculture in Uganda is developing at a fast pace and despite this trend Uganda is still unable to produce enough fresh and dry organic fruits mainly pineapple to meet the exporters demand. This current research investigated the strategies of farmers at production level by assessing the pros and cons of fruit growing, organic agriculture and fruit drying in order to understand the underlying causal factor for the low production of organic dry fruits in a major fruit producing district of Uganda.The study was carried out in two separate and distinctive areas; one which only produces and export fresh organic pineapple and the other which exports dried fruits (mainly pineapple and papaya. About 10% of the farmers in the two study areas were surveyed using questionnaires which were further followed by semi-structured interviews and participatory rural appraisals activities with various types of farmers in order to understand the different decisions and strategies of farmers.82% and 74% of farmers in the two study areas grew fruits as it gave better economic returns and for 77% and 90% respectively in the two study areas, the reasons for growing fruit was the ease of selling compared to other crops. All the farmers were relying on coffee husk for growing organic pineapples. However, 50% of the farmers want to grow pineapples (either organic or conventional but couldn't afford to buy coffee husk. Fruit drying was mainly a strategy to utilize cheap fruits during harvesting seasons for value addition. 71% and 42% of farmers in the two study areas wanted to dry fruits but it was beyond their economic capacity to buy the driers.Decision of the farmers whether to grow fruits or cereals, organic or conventional agriculture and selling the fruits as fresh or dry were dependent mainly on the economic, knowledge and resource availability of each type of practices. It is concluded that the main barrier for an increase in the production of organic dried

    Full Text Available Exporting organic fresh fruit and vegetables (FFV to the European Union could represent a great opportunity for Syrian farmers and exporters. Yet, the organic sector in Syria is comparatively young and only a very small area of FFV is organically managed. To date, little is known about Syrian farmers’ attitudes towards organic FFV production. Therefore, the aim of this study was to explore the intentions and attitudes of Syrian farmers of FFV towards organic farming and how likely they are to convert their farms to organic production within the next five years. Using a two-stage cluster sampling procedure, 266 conventional farmers of FFV in 75 villages located in different districts of Syria’s coastal region were selected for this survey. Data was collected through face-to-face interviews by a project partner in Syria (Citrus Fruit Board in Tartous from December 2012 until mid-May 2013. We used the Theory of Planned Behaviour as theoretical framework and Partial Least Squares Path Modelling as the main tool for data analysis. The results show that most farmers used at least one of the practices that are also part of certified organic production (throughout this article, the term organic agriculture, farming, and/or production always refer to certified organic agricultural production, and hold strong positive attitudes and intentions to adopt organic production within the next five years.

    This study aimed to develop a checklist for good hygiene practices (GHP) for raw material of vegetable origin using the focus groups (FGs) approach (n = 4). The final checklist for commercialization of horticultural products totaled 28 questions divided into six blocks, namely: water supply; hygiene, health, and training; waste control; control of pests; packaging and traceability; and hygiene of facilities and equipment. The FG methodology was efficient to elaborate a participatory and objective checklist, based on minimum hygiene requirements, serving as a tool for diagnosis, planning, and training in GHP of fresh vegetables, besides contributing to raise awareness of the consumers' food safety. The FG methodology provided useful information to establish the final checklist for GHP, with easy application, according to the previous participants' perception and experience.

    True or false? In selling high-value products or services: "closing" increases your chance of success; it is essential to describe the benefits of your product or service to the customer; objection handling is an important skill; and open questions are more effective than closed questions. All false, says Neil Rackham. He and his team studied more than 35,000 sales calls made by 10,000 sales people in 23 countries over 12 years. Their findings revealed that many of the methods developed for selling low-value goods just don't work for major sales. Rackham went on to introduce his SPIN-selling method, where SPIN describes the whole selling process - Situation questions, Problem questions, Implication questions, Need-payoff questions. SPIN-selling provides you with a set of simple and practical techniques which have been tried in many of today's leading companies with dramatic improvements to their sales performance.

  12. Food irradiation in the United States: irradiation as a phytosanitary treatment for fresh fruits and vegetables and for the control of microorganisms in meat and poultry

    2000-01-01

    Recently there has been a renewed focus on food irradiation in the United States (US) for the disinfestation of fresh fruits and vegetables to eliminate pests from imported agricultural commodities that could threaten the economic viability of American agriculture and for the control of bacterium E. coli 0157:H7 in beef, a pathogen that threatens the safety of the US domestic food supply. In January 1999 USDA/APHIS published in the Federal Register a rule which authorized irradiation as a guarantee treatment for papayas for movement from Hawaii to the US mainland. This treatment was never used for a number of reasons. However, in December, 1993, the US Environmental Protection Agency (EPA) published its final rule to terminate production and consumption of methyl bromide, the only remaining broad spectrum fumigant for disinfesting agricultural commodities for pests of quarantine significance on imported and exported commodities. With increased global trade pressures and the possible loss of methyl bromide as a fumigant for regulatory pests treatment made it imperative that practical treatment options be explored including irradiation. In May 1996, USDA/APHIS published a Notice of Policy which sets forth a policy statement that share positions and policies of USDA concerning the use of irradiation as a phytosanitary treatment. Subsequently in July, 1997, USDA/APHIS amended its Hawaiian regulation by increasing the dose required for papayas intended for interstate movement and by allowing carambolas and litchis also to move interstate as well. Fruits from Hawaii to the US mainland are currently being irradiated and distributed in commerce throughout the US Irradiation treatments now afford movement of many exotic fruits to the US mainland that could not be done earlier due to the lack of available treatment methods. To help combat this potential public health problem, the US Food and Drug Administration (FDA) approved treating red meat products. This process has been

    2006-12-01

    Sales and consumption of fresh pre-cut and minimally processed fruits and vegetables continue to grow. Changes occurring in life and eating styles, as well as demographic changes, have been cited as one of the reasons for the increasing demand for this type of produce. Since fresh fruits and vegetables are grown, processed or packaged in areas that may be exposed to microbial pathogen contamination, there is an increasing concern that these products may harbour microbial pathogens. In fact, a number of outbreaks linked to the consumption of contaminated fresh pre-cut fruits and vegetables have been reported. Prior to this Coordinated Research Project (CRP), studies on various chemical and physical methods of decontamination for their efficacy in destroying pathogens have been made. The use of ionizing radiation seems to have several advantages in relation to other alternative treatments; however more research was needed in order to demonstrate its efficacy without producing negative effects in the physiological traits of the fruit, and thus the commercial quality of these products. The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture initiated in 2001 a Coordinated Research Project (CRP) on the Use of Irradiation to Ensure Hygienic Quality of Fresh, Pre-cut Fruits and Vegetables and other Minimally Processed Food of Plant Origin. This CRP included 15 participants from Argentina, Brazil, Canada, Chile, China, Egypt, Hungary, India, Malaysia, Pakistan, Portugal, Turkey, United Kingdom and the United States of America (2). Research coordinated meetings were held in Rio de Janeiro, Brazil (5-9 November 2001), Belfast, UK (14-18 April 2003) and Islamabad, Pakistan (25-29 July 2005). This publication presents the research results presented in the final research coordination meeting, where the work completed during the last five years (2001-2005) was analysed

    To carry out a pilot study to determine whether a supermarket double-dollar fruit and vegetable (F&V) incentive increases F&V purchases among low-income families. Randomized controlled design. Purchases were tracked using a loyalty card that provided participants with a 5% discount on all purchases during a 3-month baseline period followed by the 4-month intervention. A supermarket in a low-income rural Maine community. A total of 401 low-income and Supplemental Nutrition Assistance Program (SNAP) supermarket customers. Same-day coupon at checkout for half-off eligible fresh, frozen, or canned F&V over 4 months. Weekly spending in dollars on eligible F&V. A linear model with random intercepts accounted for repeated transactions by individuals to estimate change in F&V spending per week from baseline to intervention. Secondary analyses examined changes among SNAP-eligible participants. Coupons were redeemed among 53% of eligible baskets. Total weekly F&V spending increased in the intervention arm compared with control ($1.83; 95% confidence interval [CI], $0.29 to $3.88). The largest increase was for fresh F&V ($1.97; 95% CI, $0.49 to $3.44). Secondary analyses revealed greater increases in F&V spending among SNAP-eligible participants who redeemed coupons ($5.14; 95% CI, $1.93 to $8.34) than among non-SNAP eligible participants who redeemed coupons ($3.88; 95% CI, $1.67 to $6.08). A double-dollar pricing incentive increased F&V spending in a low-income community despite the moderate uptake of the coupon redemption. Customers who were eligible for SNAP saw the greatest F&V spending increases. Financial incentives for F&V are an effective strategy for food assistance programs to increase healthy purchases and improve dietary intake in low-income families.

    Oil palm (Elaeis guineesis Jacq.) is the most productive oil-bearing crop, yielding more oil per area than any other oil-bearing crops. However, there are still efforts to improve oil palm yield, in order to serve consumer and manufacturer demand. Oil palm produces female and male inflorescences in an alternating cycle. So, high sex ratio (SR), the ratio of female inflorescences to the total inflorescences, is a favorable trait in term of increasing yields in oil palm. This study aims to understand the genetic control for SR related traits, such as fresh fruit bunch yield (FFB), by characterizing genes at FFB quantitative trait loci (QTLs) on linkage 10 (chromosome 6) and linkage 15 (chromosome 10). Published oil palm sequences at the FFB QTLs were used to develop gene-based and simple sequence repeat (SSR) markers. We used the multiple QTL analysis model (MQM) to characterize the relationship of new markers with the SR traits in the oil palm population. The RNA expression of the most linked QTL genes was also evaluated in various tissues of oil palm. We identified EgACCO1 (encoding aminocyclopropane carboxylate (ACC) oxidase) at chromosome 10 and EgmiR159a (microRNA 159a) at chromosome 6 to be the most linked QTL genes or determinants for FFB yield and/or female inflorescence number with a phenotype variance explained (PVE) from 10.4 to 15 % and suggest that these play the important roles in sex determination and differentiation in oil palm. The strongest expression of EgACCO1 and the predicted precursor of EgmiR159a was found in ovaries and, to a lesser extent, fruit development. In addition, highly normalized expression of EgmiR159a was found in female flowers. In summary, the QTL analysis and the RNA expression reveal that EgACCO1 and EgmiR159a are the potential genetic factors involved in female flower determination and hence would affect yield in oil palm. However, to clarify how these genetic factors regulate female flower determination, more investigation

    Full Text Available The quality of cloudy juices produced from two plum cultivars varied in chemical characteristics and native polyphenol oxidase (PPO activity, and was studied in relation to specific pectinolytic activity of enzyme preparations used for fresh fruit maceration before pressing. Process effectiveness expressed as juice yield, turbidity and the rate of transfer of anthocyanins and polyphenols were determined for five different enzyme preparations, whose activity was also analysed. Juice yields obtained after 1 hour mash maceration (50 ºC, 100 g·t−1 were between 86.6 and 95.4%. The anthocyanins content of the obtained juices strongly depended on the cultivar and ranged from 26 to 50 mg·L−1 for ‘Promis’, and from 269 to 289 mg·L−1 for ‘Čačanska Najbolja’, which could be related to the differences in the measured PPO activity (175.4 and 79.8 nkat·g−1, respectively. The type of enzyme preparation strongly affected the degradation rate of anthocyanins during juice processing. Peonidin-3-rutinoside proved to be the most stable during plum juice production in contrast to cyanidin-3-glucoside. Irrespectively of the cultivar, the juice prepared with the mixture of Rohapect PTE + Rohament PL (2 : 1 showed the highest turbidity among the investigated combinations. The results suggest that for the production of cloudy plum juice use of a preparation with low pectin methyl esterase and polygalacturonase activities and high pectin lyase activity could be recommended.

  17. Production-phase greenhouse gas emissions arising from deliberate withdrawal and destruction of fresh fruit and vegetables under the EU's Common Agricultural Policy.

    Since 1962 the Common Agriculture Policy (CAP) of the European Union (EU) has enabled payment of subsidy to some food producers for withdrawal of specific commodities - including fresh fruit and vegetables (FFV) - where market prices have fallen below a pre-set level. These deliberate withdrawals have led to large amounts of usable food (~60% of withdrawals) being destroyed on farms across the EU. Such wasted food incurs a significant climate change cost through its production-phase greenhouse gas (GHG) emissions. Here, we assess the magnitude of this FFV withdrawal and destruction, its spatial and temporal trends, and its associated GHG emissions between 1989 and 2015. We find the total mass of avoidable FFV losses occurring as a result of these EU CAP market interventions for this 26-year period to be 23.6Mt. The production-phase GHG emissions associated with the withdrawn FFV that was subsequently destroyed amount to 5.1Mt CO 2 e over this period. We also find that, with each successive Common Market Organisation (CMO) reform there has been a marked reduction (~95% between 1989 and 2015) in the quantity of such deliberate withdrawals. Surprisingly, however, whilst the absolute quantity of FFV withdrawn and destroyed has fallen, the proportion of withdrawals that is destroyed remained roughly static at an average of about 60%. Finally, to inform debate on action needed to address FFV specifically, and food loss and waste more generally, we highlight potential scenarios and mechanisms to reduce withdrawals, avoid FFV destruction and improve alternative use of withdrawn food in the future.

    The article discusses the marketing and sales of energy generated from renewable energy sources. To purchase environmental energy in the USA, the consumer need do no more than tick a box on a sheet of paper. But, it is not just households that opt for green energy: businesses are also willing customers. A factor in the success in selling green energy to big business is that the retail price of wind power can be held constant over periods of several years, whereas fossil fuel prices can fluctuate wildly. Details of sources and sales of the top ten companies selling green energy are given

    Mass production of the Mediterranean fruit fly (Medfly) larvae, Ceratitis capitata Wiedemann, requires a rearing diet (Tanaka et al. 1969 1970) of which the nutrient requirements and digestibility have not been established. Setbacks in rearing productivity from the expected 100% yield to as low as 3% yield may occasionally be directly attributed to insecticide contamination or a variety of possible cause(s) (Kobayashi, 1993). These causes include inadequate nutrition, poor diet formulation, overcrowding of either microorganisms or Drosophila, or to the inherent processes of oxidative or microbial deterioration of nutrients. The purpose of this study was to establish the nutritional status of the Mediterranean fruit fly diet through a material balance study for changes in proximate composition (i.e., moisture, protein, fat, ash, carbohydrates), amino acids, minerals between fresh and spent diets, and in the fruit fly larvae themselves

    The purpose of this study was to test the impact of distributing coupons redeemable at farmers markets plus an educational intervention on fruit and vegetable (F&V) purchase and consumption in overweight patients with type 2 diabetes (T2DM). Seventy-eight participants with T2DM being followed at Jacobi Medical Center, a large public hospital in the Bronx, New York, were randomized to receive the standard of care or a 1-hour session focused on benefits of F&V consumption and $6 in coupons. Questionnaires assessed demographics, F&V intake, and farmers market purchasing at baseline and 12 weeks. Clinical parameters were obtained through chart review at baseline and at 12 weeks. Participants were predominantly Latino, females, and low income. At 12 weeks, there was a statistically significant increase in the number of participants in the intervention arm who reported purchasing from a farmers market. In addition, there was a minimal increase in fresh fruit intake in the intervention arm at 12 weeks. Focused education combined with a small economic incentive resulted in an increase in purchasing behavior and fresh fruit intake per day. A more intense behavioral intervention combined with increased access may result in a significant impact on obesity and diabetes, particularly among low-income and racially diverse communities.

    Kazakhstan's government seems keen to involve foreign companies in financing the large scale exploitation of Central Asia's hydrocarbon reserves. Despite domestic uncertainty about free market ethics, the country's rulers seem keen to sell off some of its present wealth, in terms of oil production, in order to raise finance for internal projects. The author explores which of several options for financing these large projects would prove most beneficial to the Kazakhs themselves. (UK)

  7. Selling the brand inside.

    Mitchell, Colin

    2002-01-01

    When you think of marketing, chances are your mind goes right to your customers--how can you persuade more people to buy whatever it is you sell? But there's another "market" that's equally important: your employees. Author Colin Mitchell argues that executives by and large ignore this critical internal audience when developing and executing branding campaigns. As a result, employees end up undermining the expectations set by the company's advertising--either because they don't understand what the ads have promised or because they don't believe in the brand and feel disengaged or, worse, hostile toward the company. Mitchell offers three principles for executing internal branding campaigns--techniques executives can use to make sure employees understand, embrace, and "live" the brand vision companies are selling to the public. First, he says, companies need to market to employees at times when the company is experiencing a fundamental challenge or change, times when employees are seeking direction and are relatively receptive to new initiatives. Second, companies must link their internal and external marketing campaigns; employees should hear the same messages that are being sent to the market-place. And third, internal branding campaigns should bring the brand alive for employees, creating an emotional connection to the company that transcends any one experience. Internal campaigns should introduce and explain the brand messages in new and attention-grabbing ways and then reinforce those messages by weaving them into the fabric of the company. It is a fact of business, writes Mitchell, that if employees do not care about or understand their company's brands, they will ultimately weaken their organizations. It's up to top executives, he says, to give them a reason to care.

    Full Text Available This study aims to analyze purchase policies to fruits and vegetables in supermarkets in Campo Grande, Brazilian Midwest. Thirteen interviews were conducted with representatives from supermarkets, small, medium and large, responsible for purchasing fresh vegetables. By analyzing the responses obtained through interviews, we can observe that producers make almost the entire supply of fruits and vegetables in large supermarkets from other states, and the small and medium establishments usually buy more with the local producer. For retailers, the fruits and vegetables represent an important factor to create internal circulation of customers in stores and a factor of attraction of clients too, in addition, this products offer high profitability. For the supermarket, the fruits and vegetables locally produced are fresher and have lower comparative cost. However, supply regularity, the volume and variety offered by local producers are considered unsatisfactory.O presente estudo objetiva analisar as formas de compra dos supermercados para o abastecimento de hortaliças em Campo Grande. Foram realizadas treze entrevistas com representantes de supermercados de pequeno, médio e grande porte, responsáveis pelas compras destes produtos. Os resultados revelam que praticamente todo o fornecimento de hortaliças nos grandes supermercados é feito por produtores de outros estados, sendo que os estabelecimentos de pequeno e médio porte ainda conseguem abastecer-se satisfatoriamente com os produtores locais. Para os varejistas, o setor de hortaliças representa importante espaço de geração de tráfego interno de clientes nas lojas, sendo um fator de atração. Pode-se verificar, ainda, que as hortaliças produzidas localmente atendem ao requisito "frescor" e também possuem menor custo comparativo, porém, a regularidade no fornecimento, o volume e a variedade oferecida pelos produtores locais são considerados insatisfatórios.

    Bacteria of the genus Cronobacter are emerging food-borne pathogens. Foods contaminated with Cronobacter spp. may pose a risk to infants or adults with suppressed immunity. This study was aimed at determining the microbiological quality of ready-to-eat (RTE) plant-origin food products available on the Polish market with special emphasis on the prevalence of Cronobacter genus bacteria. Analyses were carried out on 60 samples of commercial RTE type plant-origin food products, including: leaf vegetables (20 samples), sprouts (20 samples) and non-pasteurized vegetable, fruit and fruit-vegetable juices (20 samples). All samples were determined for the total count of aerobic mesophilic bacteria (TAMB) and for the presence of Cronobacter spp. The isolates of Cronobacter spp. were subjected to genetic identification and differentiation by 16S rDNA sequencing, PCR-RFLP analysis and RAPD-PCR and evaluation of antibiotic susceptibility by the disk diffusion assay. The TAMB count in samples of lettuces, sprouts and non-pasteurized fruit, vegetable and fruit-vegetable juices was in the range of 5.6-7.6, 6.7-8.4 and 2.9-7.7 log CFU g -1 , respectively. The presence of Cronobacter spp. was detected in 21 (35%) samples of the products, including in 6 (30%) samples of leaf vegetables (rucola, lamb's lettuce, endive escarola and leaf vegetables mix) and in 15 (75%) samples of sprouts (alfalfa, broccoli, small radish, lentil, sunflower, leek and sprout mix). No presence of Cronobacter spp. was detected in the analyzed samples of non-pasteurized fruit, vegetable and fruit-vegetable juices. The 21 strains of Cronobacter spp. isolated from leaf vegetable and sprouts included: 13 strains of C. sakazakii, 4 strains of C. muytjensii, 2 strains of C. turicensis, one strain of C. malonaticus and one strain of C. condimenti. All isolated C. sakazakii, C. muytjensii, C. turicensis and C. malonaticus strains were sensitive to ampicillin, cefepime, chloramphenicol, gentamycin

    Full Text Available El cooperativismo agrario ha estado ligado desde sus orígenes al sector de las frutas y hortalizas, sector que arrastra desde hace años una problemática de carácter estructural, incrementada, sobretodo en el caso de la fruta, por las graves crisis de precios, la saturación de los mercados y una competencia creciente de las importaciones de terceros países. En este difícil marco, los productores deben seguir invirtiendo para mantener la competitividad y la rentabilidad de sus explotaciones, y las cooperativas, por su importancia económica, deben acometer políticas que permitan garantizar la viabilidad de dicho sector. En el presente trabajo realizamos un análisis del sector cooperativo frutícola catalán, con el fin de detectar sus puntos fuertes y débiles, así como posibles carencias y demandas. Las conclusiones muestran que las cooperativas son importantes en el sector de la fruticultura, debido sobretodo a su contribución activa a la conservación del territorio y su papel generador de empleo en numerosas zonas rurales. Pero se hace necesario la adopción de firmes decisiones y la implantación de medidas de apoyo que permitan garantizar los intereses de los socios y las necesidades de los consumidores./ The agricultural cooperatives have been linked from the origins to fruit and vegetable sector. This sector dragged on for years a structural problem, increased, especially in the case of fruit, for serious price crisis, the market saturation and increasing competition. In this difficult context, producers must keep investing to maintain competitiveness and profitability. The cooperatives, by their economic importance, should undertake policies to ensure the viability of this sector. In this paper we do an analysis of Catalan fruit cooperative sector, to identify their strengths and weaknesses, and possible deficiencies and demands. The findings show that cooperatives are important in the fruit growing sector, mainly due to their

    Full Text Available Os sistemas de tutoramento e condução influem no desenvolvimento da planta do tomateiro e na qualidade do fruto produzido. Para avaliar a influência de três sistemas de tutoramento e dois de condução da planta do tomateiro na produção classificada de frutos comercializáveis, foram conduzidos dois experimentos, de agosto a dezembro/1999 (exp. 1 e de 2000 (exp. 2 em Viçosa (MG. O delineamento foi em blocos ao acaso com três repetições, no esquema fatorial 3x2, tutoramento e condução, respectivamente. Avaliaram-se os seguintes métodos de tutoramento: T1, tradicional (V invertido, T2, triangular e T3, vertical e duas formas de condução, com uma e duas hastes por planta. Independentemente do tratamento, as plantas foram podadas acima do sexto cacho. Observaram-se diferenças entre os sistemas de tutoramento, condução e entre os anos de cultivo em relação às características avaliadas, sendo que ocorreu interação entre estes efeitos apenas para as características produção de frutos comercializáveis e produção total. O tutoramento vertical proporcionou aumento na produção de frutos de tamanho grande e diminuição na produção de frutos de tamanho médio e frutos não comercializáveis, quando comparado com os outros métodos de tutoramento. Independentemente do sistema de tutoramento, o tomateiro cultivado com uma haste produziu mais frutos de tamanho grande, de maior valor comercial, enquanto as plantas conduzidas com duas hastes produziram mais frutos de tamanho médio e pequeno.The main reason for staking and training tomato plants is to keep plants and fruits off the ground to reduce losses and to improve the quality of the production.

    The complex fruit and vegetable commercialization system requires constant marketing studies for elaboration and implementation of strategies and actions to improve it. The objective of this study was to evaluate fruits and vegetables commercialization in the Mineiros municipality, Goiás State, Brazil, in order to provide information for retail trade. The survey was carried out in retail trade equipments, such as supermarkets, grocery stores, and street markets, from December 2005 to January 2006, by means of questionnaire application. Among the evaluated fruits, orange reached the higher weekly commer-cialization volume (7,196 kg, followed by banana (2,812 kg, apple (2,526 kg, and pineapple (1,935 kg. For vegetables, tomato (7,854 kg, watermelon (6,600 kg, onion (4,882 kg, and potato (4,272 kg were the most commercialized items. Supermarkets and grocery stores are responsible for most of the fruit and vegetable commercialized in the region. The local horticulture agribusiness does not supply the regional demand, the marketing for those products depending on long distance suppliers.

    A new microextraction method named salt and pH-induced homogeneous liquid-liquid microextraction has been developed in a home-made extraction device for the extraction and preconcentration of some pyrethroid insecticides from different fruit juice samples prior to gas chromatography-mass spectrometry. In the present work, an extraction device made from two parallel glass tubes with different lengths and diameters was used in the microextraction procedure. In this method, a homogeneous solution of a sample solution and an extraction solvent (pivalic acid) was broken by performing an acid-base reaction and the extraction solvent was produced in whole of the solution. The produced droplets of the extraction solvent went up through the solution and solidified using an ice-bath. They were collected without centrifugation step. Under the optimum conditions, limits of detection and quantification were obtained in the ranges of 0.006-0.038, and 0.023-0.134ngmL -1 , respectively. The enrichment factors and extraction recoveries of the selected analytes ranged from 365-460 to 73-92%, respectively. The relative standard deviations were lower than 9% for intra- (n = 6) and inter-day (n = 4) precisions at a concentration of 1ngmL -1 of each analyte. Finally, some fruit juice samples were effectively analyzed by the proposed method. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available A novel aspartic protease with HIV-1 RT inhibitory activity was isolated and characterized from fruiting bodies of the wild mushroom Xylaria hypoxylon. The purification protocol comprised distilled water homogenization and extraction step, three ion exchange chromatographic steps (on DEAE-cellulose, Q-Sepharose, and CM-cellulose in succession, and final purification was by FPLC on Superdex 75. The protease was adsorbed on all the three ion exchangers. It was a monomeric protein with a molecular mass of 43 kDa as estimated by SDS-PAGE and FPLC. Its N-terminal amino acid sequence was HYTELLSQVV, which exhibited no sequence homology to other proteases reported. The activity of the protease was adversely affected by Pepstatin A, indicating that it is an aspartic protease. The protease activity was maximal or nearly so in the pH range 6–8 and in the temperature range 35–60°C. The purified enzyme exhibited HIV-1 RT inhibitory activity with an IC50 value of 8.3 μM, but was devoid of antifungal, ribonuclease, and hemagglutinating activities.

    Sensory evaluation is the ideal tool for shelf-life determination. With the objective to develop an easy shelf-life indicator, color (L*, a*, b*, chroma and hue angle), total soluble solids (TSS), firmness (F), pH, acidity, and the sensory attributes of appearance, brightness, browning, odor, flavor, texture, color, acidity and sweetness were evaluated in fresh cut mangoes (FCM) stored at 5, 10, 15 and 20 °C. Overall acceptability was evaluated by consumers. Correlation analysis between sensory attributes and physicochemical variables was carried out. Physicochemical cut-off points based on sensory attributes and consumer acceptability was obtained by regression analysis and utilized to estimate FCM shelf-life by kinetic models fitted to each variable. The validation of the model was done by comparing the shelf life estimated by kinetic models and consumers. It was recorded large correlations between appearance, brightness, and color with L*; appearance and color with chroma and hue angle; sweetness and flavor with TSS, and between F and texture. The shelf life estimated based on consumer using a 9 point hedonic scale was in the range of 10-12, 2.3-2.6, 1.3-1.5 and 1.0-1.1 days for 5, 10, 15 and 20 °C. It was recorded large correlation coefficients between the shelf life estimated by consumer acceptability scores and physicochemical variables. Kinetic models based on physicochemical variables showed a tendency to overestimate the shelf life as compared with the models bases on the sensory attributes. It was concluded that physicochemical variables can be used as a tool to estimate the FCM shelf life.

    To quantify and model the combined effects of temperature (T) (10-40°C), water activity (a w ) (0·993-0·818) and CO 2 concentration (9·4-55·1%, v/v) on the growth rate of Aspergillus niger and Alternaria alternata that cause spoilage during the storage and packaging of dates. The effects of environmental factors were studied using the γ-concept. Cardinal models were used to quantify the effect of studied environmental factors on the growth rates. Firstly, the cardinal parameters were estimated independently from experiments carried out on potato dextrose agar using a monofactorial design. Secondly, model performance evaluation was conducted on pasteurized date paste. The boundary between growth and no-growth was predicted using a deterministic approach. Aspergillus niger displayed a faster growth rate and higher tolerance to low a w than Al. alternata, which in turn proved more resistant to CO 2 concentration. Minimal cardinal parameters of T and a w were lower than those reported in the literature. The combination of the a w and CO 2 effects significantly affected As. niger and Al. alternata growth. The γ-concept model overestimated growth rates, however, it is optimistic and provides somewhat conservative predictions. The developed model provides a decision support tool for the choice of the date fruit conservation mode (refrigeration, drying, modified atmospheric packaging or their combination) using T, a w and CO 2 as environmental factors. © 2016 The Society for Applied Microbiology.

    Diagnosis of fruit sensitisation by skin prick test (SPT) is fast and easy to perform. Nevertheless, some fruit is not available throughout the year. Freezing aliquots of these fresh fruits to be defrosted would be a good solution to perform SPT at any time. To compare the reproducibility of SPT with Rosaceae and Cucurbitaceae frozen fruit with fresh and commercial fruit extracts. SPT with the following fruit were performed: apricot, cherry, strawberry, nectarine, Japanese medlar, peach, (peel and pulp), yellow and red plum, melon and watermelon. We compared fresh fruit, commercial extract and fruit which had been frozen at -18 degrees C. Results were read by planimetry (Inmunotek prick-film) after 15 minutes. The study group comprised 48 patients (9 males, 39 females) with a mean age of 31, 6 +/- 2.0 years. Concordance of positive and negative results was extremely high and significant in all cases. Correlation between frozen fruit and commercial extract, frozen fruit and fresh and commercial extract and fresh fruit was statistically significant in all cases except for strawberry. The use of frozen fruit is a valid method, as the performance of the SPT is similar to that of fresh fruit. This enables diagnostic procedures with seasonal fruit at any time of the year.

    The fresh meat industry is changing the way it markets its products. The decline in red meat consumption that has resulted from greater consumer concerns about the "healthfulness" of red meat, coupled with changes in consumer lifestyles emphasizing a need for convenience is contributing to the diminishment of "commodity selling" in favor of a true "marketing" approach (Pierson and Allen, 1986).

    Full Text Available Vegetables and fruits have beneficial properties for human health, because of the presence of phytochemicals, but their concentration can fluctuate throughout the year. A systematic study of the phytochemical content in tomato, eggplant, carrot, broccoli and grape (fresh and fresh-cut has been performed at different seasons, using liquid chromatography coupled to triple quadrupole mass spectrometry. It was observed that phenolic acids (the predominant group in carrot, eggplant and tomato were found at higher concentrations in fresh carrot than in fresh-cut carrot. However, in the case of eggplant, they were detected at a higher content in fresh-cut than in fresh samples. Regarding tomato, the differences in the content of phenolic acids between fresh and fresh-cut were lower than in other matrices, except in winter sampling, where this family was detected at the highest concentration in fresh tomato. In grape, the flavonols content (predominant group was higher in fresh grape than in fresh-cut during all samplings. The content of glucosinolates was lower in fresh-cut broccoli than in fresh samples in winter and spring sampling, although this trend changes in summer and autumn. In summary, phytochemical concentration did show significant differences during one-year monitoring, and the families of phytochemicals presented different behaviors depending on the matrix studied.

    Full Text Available This concept paper summarizes key “hotspots” for waste generation along the food supply chain and identifies a range of existing solutions/measures that can help producers, retailers and consumers reduce the amount of food that is wasted. The majority of food waste of 71–92 kg/head/year in Western Europe was found to originate from private households (61%, followed by restaurants and canteens (17% and then supermarkets (5%; 59%–65% (of this food waste (71–92 kg can be avoided and 54% thereof are fruit and vegetables. Since ethylene accelerates fruit ripening and its accumulation can lead to fruit decay and waste and new portable instruments now enable continuous in-situ determination of ethylene along the food chain, there is a possible key to reducing food waste of perishable, fresh produce. Hence, suggested countermeasures at the field level are use of ethylene inhibitors (AVG as “Retain” or MCP as “Harvista”, the former prevents pre-mature fruit drop in pome fruit, incentives for processing fruit of industrial grade and whole crop purchase (“WCP”. Along the supply chain, applications of ethylene inhibitors (e.g., 1-MCP as “SmartFresh” absorber strips (e.g., “It’s Fresh”, Sensitech, bags (e.g., “Peakfresh” as well as simply cooling and venting, and shading to avoid sun exposure.

    Science popularization is ÒtheÓ tool to bridge the gap between society at large and the world of science. Compared to formal science communication Ð science taught in schools Ð informal science communication, made by the TV, the press, Òscience centresÓ and visits to scientific laboratories, has an important advantage: it makes the public meet science in a direct, informal way and on its own terms. The public is given an opportunity to develop a personal relationship with science, according to the needs, interests and abilities of the individual. But selling science is a tough job. The object of the sale is not a consumer good, but rather ideas and concepts that are sometimes so complex and distant from common sense that translating them into a comprehensible language and creating interest in the public without betraying the scientific truth is almost impossible.

    2004-01-01

    Over the past decade, the distribution of household incomes has shifted so much that a much larger proportion of consumers now earn significantly higher-than-average incomes--while still falling short of being truly rich. As a result, what used to be a no-man's-land for new product introductions has in many categories become an extremely profitable "new middle ground." How can marketers capitalize on this new territory? The key, say the authors, is to rethink the positioning and design of offerings and the ways they can be brought to market. Take, for instance, how Procter & Gamble redefined the positioning map for tooth-whitening solutions. A decade ago, dental centers were popularizing expensive bleaching techniques that put the price of a professionally brightened smile in the 400 dollars range. At the low end, consumers also had the choice of whitening toothpastes that cost anywhere from 2 dollars to 8 dollars. P&G wisely positioned itself between the two ends, successfully targeting the new mass market with its 35 dollars Whitestrips. In product categories where it's clear the middle ground has already been populated, it's important for companies to design or redesign offerings to compete. An example is the Polo shirt. How do you sell a man yet another one after he's bought every color he wants? Add some features, and call it a golf shirt. Here, marketers have introduced designs based on the concept of "occasional use" in order to stand out. Finally, companies wishing to reach the "almost rich" can change how they go to market. Perhaps no mass retailer has made a stronger bid for the mass affluent than Target Stores, which has pioneered a focus the company itself characterizes as upscale discount. The strategy has made Target an everyday shopping phenomenon among well-heeled urbanites and prosperous professionals.

  15. Censoring and Selling Film Noir

    Directory of Open Access Journals (Sweden)

    Sheri Chinen Biesen

    2015-05-01

    Full Text Available Film noir is known for its duplicity. Industry censors considered 1940s noir cinema provocative, salacious and ‘sordid.’ Hollywood studios walked a fine line between appearing to comply with Hays office Production Code censorship while simultaneously pushing the envelope of its moral constraints, then hyping and sensationalizing censorable sex, violence and hard-hitting themes to sell noir films to the public. In fact, studios capitalized on the racy explicit nature of noir pictures in publicity contradicting assurances of censorial compliance. For instance, censor Joseph Breen was “shocked” when MGM purchased James Cain’s The Postman Always Rings Twice. It was banned for a decade. Yet, ten years later as filmmakers adapted hardboiled fiction, Breen assured religious groups it would “not be offensive.” Yet, it was promoted as “torrid,” “too hot to handle” with Lana Turner in a bathing suit finding “Love at Laguna Beach” with hunky John Garfield who clamored, “You must be a she-devil,” suggesting far more sex, skin and “savage boldness” than is shown in the film. Film noir responded to Production Code censorship and other regulatory factors, including Office of War Information Bureau of Motion Pictures restrictions on Hollywood screen depictions of the domestic American home front (or overseas combat front, and Office of Censorship strictures such as a wartime ban on screen gangsters as ‘un-American’ for propaganda purposes in World War II-era noir films centering on criminals. These multiple censorship entities often collided. This regulatory climate catalyzed the development of film noir, a dark cycle of shadowy 1940s-50s crime films that boomed by World War II and evolved over the postwar era. I will investigate extensive primary archival research—including scripts, memos from industry censors, writers, directors, producers, and publicity records—to compare how film noir was censored and sold.

  5. Preservation of fresh avocados by irradiation

    International Nuclear Information System (INIS)

    Karmelic, J.

    1985-01-01

    Avocado is the fifth most important fruit in Chile, which exports fruits to Europe. The production of avocado has increased from 14,000 metric tons in 1978 to a projected 70,000 metric tons in 1985. The main problem of shipping fresh Chilean avocado to Europe has been its short shelf life, being around 24 days with a maximum of 30 days. To market fresh Chilean avocados in Europe, adequate keeping quality must be assured for 40 or more days. A project on the preservation of fresh Chilean avocados supported by the International Atomic Energy Agency (IAEA) takes the approach of combining mild heat and low-dose gamma-radiation. Two varieties of avocados were studied (Hass and Fuerte) and two batches of each were treated: one at the beginning and the other at the end of the picking season. In each case a combination of heat treatment (46 0 C for 10 minutes) and irradiation was applied. Fruits were individually wrapped with flexible PVC and placed in cardboard boxes containing 20 each. Fruits treated with 25,50, and 100 Gy were compared with two controls: one with and another without individual wrapping

  7. Reconsidering Kantian arguments against organ selling.

    Science.gov (United States)

    Alpinar-Şencan, Zümrüt

    2016-03-01

    Referring to Kant's arguments addressing the moral relationship between our bodies and ourselves is quite common in contemporary debate about organ selling, although he does not provide us with any specific arguments related to this debate. It is widely argued that the most promising way to show the moral impermissibility of organ selling is to mount an argument on Kantian grounds. This paper asks whether it is possible to argue coherently against organ selling in a Kantian framework. It will be shown that by mounting the argument on Kantian grounds no compelling argument can be given against sale of organs, either because the arguments apply to donation of organs, too, or the arguments are not convincing for other independent reasons. In the first section, it will be argued that donation and selling are not distinguishable in a Kantian framework, since the concern about commodification of the body and its parts shall be raised by both actions. In the second section, some contemporary accounts inspired by Kant will be presented and discussed separately. It will be argued that the reasons for promoting organ donation while arguing against selling clash with each other in an unconvincing way.

    Full Text Available Genotypic, phenotypic and environmental correlations were estimated for all possible pairs among eleven characters of tomatoes. Fifteen treatments including five parents and ten hybrids of Instituto Agronômico (IAC tomato breeding program were evaluated using a randomized complete block experimental design, with tree replications in Itatiba, São Paulo state, Brazil, during 2005/2006. The following traits were evaluated: fruit yield per plant (FP, fruit number per plant (FN, average fruit weight (FW, cluster number per plant (CN, fruit number per cluster (FC, number of locules per fruit (NL, fruit length (FL, fruit width (WI, fruit wall thickness (FT, total soluble solids (SS, and total titratable acidity (TA. The genotypic (rG, phenotypic (rF and environmental correlations (rA for two pairs of plant traits were estimated using the Genes© program. High similarity was found among the estimates of genotypic and phenotypic correlations. Positive and high phenotypic and genotypic correlations were observed between FP and the traits FN, FW and FT, and these associations contributed for yield increasing. FW and FT contributed to yield increase and should be considered together as primary yield components in tomato. Positive values of the genotypic and phenotypic correlations revealed that FP influenced FN with high direct effect and significant positive correlation. These traits may be included as the main selection criteria for tomato yield improvement.Correlações fenotípica, genotípica e ambiental foram estimadas entre todos os possíveis pares de onze caracteres de tomate de mesa.

    2014-08-01

    Full Text Available Fruits are one of the oldest forms of food known to man. There are many references to fruits in ancient literature. According to Quran, the fruits like grape, date, fig, olive and pomegranate are gifts and heavenly fruits of God.  Fresh and dry fruits are the natural staple food of man. They contain substantial quantities of essential nutrients in a rational proportion. Persons subsisting on this natural diet will always enjoy good health. Moreover, fresh and dry fruits are thus not only a good food but also a good medicine. Holy Quran is one of the reference books describing the importance of plants used for different ailments in various verses. There are several verses in Quran talking about the fruits in Paradise, including; date, olive, pomegranate, grape, banana and fig. What has been mentioned in the Quran is what scientists have achieved over the time, since the Quran is governed by logic. Although we do not know the reasons for many things in the Quran, we consider it as the foundation.

    Goldenberg, Livnat; Yaniv, Yossi; Porat, Ron; Carmi, Nir

    2018-01-01

    During the last decade, there has been a continuous rise in consumption and global marketing of fresh, easy-to-peel mandarins, with current annual production of nearly 29 million tons. Nevertheless, most of the existing knowledge on quality traits of citrus fruit comes from research conducted on oranges and grapefruit, which are the main products for the citrus juice manufacturing industry; relatively little is yet known regarding the unique fruit quality traits of mandarins, nor about the great diversity in these traits among the various natural sub-groups and varieties of mandarins. In the present review we discuss the physiological, biochemical, and molecular factors governing key fruit quality attributes of mandarins, including fruit colour, size and shape, ease of peeling, seedlessness, flavour, and nutritional quality. Fruit colour, size, and shape contribute to external appearance; peelability and seedlessness to ease of consumption; and flavour and nutritional quality to internal quality. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    Directory of Open Access Journals (Sweden)

    Robert J. Cannon

    2018-04-01

    Full Text Available Global production and demand for tropical fruits continues to grow each year as consumers are enticed by the exotic flavors and potential health benefits that these fruits possess. Volatile sulfur compounds (VSCs are often responsible for the juicy, fresh aroma of tropical fruits. This poses a challenge for analytical chemists to identify these compounds as most often VSCs are found at low concentrations in most tropical fruits. The aim of this review is to discuss the extraction methods, enrichment techniques, and instrumentation utilized to identify and quantify VSCs in natural products. This will be followed by a discussion of the VSCs reported in tropical and subtropical fruits, with particular attention to the odor and taste attributes of each compound. Finally, the biogenesis and enzymatic formation of specific VSCs in tropical fruits will be highlighted along with the contribution each possesses to the aroma of their respective fruit.

    2017-11-27

    To obtain insight into tobacco retailing by alcohol-licenced premises, in order to understand the financial importance of tobacco sales for such retailers. Data were collected by a telephone survey of 1042 clubs, hotels and packaged liquor outlets in New South Wales, Australia. The response rate was 86.1%. Qualitative and quantitative data were obtained. Logistic and linear regression were used to determine factors associated with the probability of selling and stopping selling and the importance of cigarette sales. More than a third (36.4%) of premises contacted did not sell cigarettes. 147 (an estimated 18.1% of those who had ever sold) had stopped selling. There were significant differences in the probability of selling, in the reported importance of cigarette sales and in the probability of stopping selling, between different outlet types and other outlet characteristics (number of gaming machines, proximity of nearest alternative tobacco retailer and remoteness). Outlets where alcohol can be consumed were more likely to rate cigarette sales as 'not important' than 'important'. Despite claims by tobacco companies that tobacco sales are important for many Australian retailers, tobacco sales appear to be of limited importance for alcohol-licenced premises. This means that opposition to stopping tobacco sales where alcohol is consumed and/or sold may be less than expected. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  5. Sewage sludge and how to sell it

    Energy Technology Data Exchange (ETDEWEB)

    Knapp, I M

    1977-10-01

    Largo, Florida dries its sludge and sells it as fertilizer for $80 to $169/T. The sludge processing plant capable of turning common sludge into a dry, pelletized soil conditioner was only slightly more expensive than the previously proposed concrete drying beds which would have required disposal of the dried residue. The city's experience in setting up the plant and marketing the finished product is discussed. The true advantage of selling heat-dried sludge is that residents of the surrounding area, knowing the value of the product to their lawns and shrubs, will provide the transportation for the product and the physical labor to spread it over an area wider than most municipalities could afford to own or operate. The current production cost of $140/T is high, but the addition of a sludge prethickener-conditioner process and expected future economies of scale as the volume of sludge treated increases should lower per ton costs.

  8. Does organ selling violate human dignity?

    Science.gov (United States)

    Alpinar-Şencan, Zümrüt; Baumann, Holger; Biller-Andorno, Nikola

    2017-11-01

    Shortages in the number of donated organs after death and the growing number of end-stage organ failure patients on waiting lists call for looking at alternatives to increase the number of organs that could be used for transplantation purposes. One option that has led to a legal and ethical debate is to have regulated markets in human organs. Opponents of a market in human organs offer different arguments that are mostly founded on contingent factors that can be adjusted. However, some authors have asked the question whether we still have a reason to believe that there is something wrong with offering human organs for sale for transplantation purposes, even if the circumstances under which the practice takes place are improved. One prominent argument regarding this appeals to the notion of human dignity. It is argued that organ selling violates human dignity. This paper presents a systematic discussion of dignity-based arguments in the organ selling debate, and then develops a social account of dignity. It is argued that allowing the practice of organ selling inherently runs the risk of promoting the notion that some persons have less worth than others and that persons have a price, which is incompatible with dignity. The approach is defended against possible objections and it is shown that it can capture the notion that autonomy is linked to human dignity in important ways, while dignity at the same time can constrain the autonomous choices of persons with regards to certain practices.

  9. Application of visible/near infrared spectroscopy to quality control of fresh fruits and vegetables in large-scale mass distribution channels: a preliminary test on carrots and tomatoes.

    Beghi, Roberto; Giovenzana, Valentina; Tugnolo, Alessio; Guidetti, Riccardo

    2018-05-01

    The market for fruits and vegetables is mainly controlled by the mass distribution channel (MDC). MDC buyers do not have useful instruments to rapidly evaluate the quality of the products. Decisions by the buyers are driven primarily by pricing strategies rather than product quality. Simple, rapid and easy-to-use methods for objectively evaluating the quality of postharvest products are needed. The present study aimed to use visible and near-infrared (vis/NIR) spectroscopy to estimate some qualitative parameters of two low-price products (carrots and tomatoes) of various brands, as well as evaluate the applicability of this technique for use in stores. A non-destructive optical system (vis/NIR spectrophotometer with a reflection probe, spectral range 450-1650 nm) was tested. The differences in quality among carrots and tomatoes purchased from 13 stores on various dates were examined. The reference quality parameters (firmness, water content, soluble solids content, pH and colour) were correlated with the spectral readings. The models derived from the optical data gave positive results, in particular for the prediction of the soluble solids content and the colour, with better results for tomatoes than for carrots. The application of optical techniques may help MDC buyers to monitor the quality of postharvest products, leading to an effective optimization of the entire supply chain. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  10. Ionizing energy treatment of fruit and vegetables

    International Nuclear Information System (INIS)

    Rigney, C.J.

    1983-01-01

    The potential of ionising energy treatment of fresh fruit and vegetables may be considered within four major use areas. The shelf life of such fruits as bananas, mangoes and pawpaws can be extended by a direct physiological effect on the fruit. This treatment renders the fruit less sensitive to ethylene, a natural senescence-promoting chemical, and retards the onset of the climactric rise in respiration which is associated with fruit ripening. Postharvest decay caused by radio-sensitive organisms can also be controlled by low irradiation treatments, although this is only applicable in cases where the host fruit is less sensitive to the treatment than the decay causing organism. The sprouting of onions and potatoes can be controlled by a single low dose treatment which has a direct effect on the meristematic tissue. By killing insects of quarantine significance the interstate and export marketing of Australian fresh fruit may be expanded, with a consequent expansion of these horticultural industries. Ionising energy treatment of fruit and vegetables is therefore a valuable postharvest tool to improve the quality of fresh produce on local and export markets

Decoction or extraction of Chinese traditional medicine, such as Alpinia Officinarum, Amarphalus Konjac K., stemona etc, could be used in fresh-keeping for orange, apple, strawberry, edible fungi and so on. Garlic could be used in fresh-keeping for orange. Phytic acid and fresh-keeping agents compounded with Phytic acid could extend storage periods of easily rotting fruits and vegetables, such as strawberry, banana, cantaloup, edible fungi and so on, and better keep original fresh condition. Extraction of Snow Fresh, Semper Fresh, Arthropod shell extraction, and halite also had better effect on preservation and fresh-keeping for fruits and vegetables. Main problems exsited in the application of natural preservatives for fruits and vegetables were showed in this article and the applying prospect were discussed too.

  4. Phenylpropenes: Occurrence, Distribution, and Biosynthesis in Fruit.

    Science.gov (United States)

    Atkinson, Ross G

    2018-03-14

    Phenylpropenes such as eugenol, chavicol, estragole, and anethole contribute to the flavor and aroma of a number of important herbs and spices. They have been shown to function as floral attractants for pollinators and to have antifungal and antimicrobial activities. Phenylpropenes are also detected as free volatiles and sequestered glycosides in a range of economically important fresh fruit species including apple, strawberry, tomato, and grape. Although they contribute a relatively small percentage of total volatiles compared with esters, aldehydes, and alcohols, phenylpropenes have been shown to contribute spicy anise- and clove-like notes to fruit. Phenylpropenes are typically found in fruit throughout development and to reach maximum concentrations in ripe fruit. Genes involved in the biosynthesis of phenylpropenes have been characterized and manipulated in strawberry and apple, which has validated the importance of these compounds to fruit aroma and may help elucidate other functions for phenylpropenes in fruit.

    2008-01-01

    Full Text Available Fish species identification and automated fish freshness assessment play important roles in fishery industry applications. This paper describes a method based on support vector machines (SVMs to improve the performance of fish identification systems. The result is used for the assessment of fish freshness using artificial neural network (ANN. Identification of the fish species involves processing of the images of fish. The most efficient features were extracted and combined with the down-sampled version of the images to create a 1D input vector. Max-Win algorithm applied to the SVM-based classifiers has enhanced the reliability of sorting to 96.46%. The realisation of Cyranose 320 Electronic nose (E-nose, in order to evaluate the fish freshness in real-time, is experimented. Intelligent processing of the sensor patterns involves the use of a dedicated ANN for each species under study. The best estimation of freshness was provided by the most sensitive sensors. Data was collected from four selected species of fishes over a period of ten days. It was concluded that the performance can be increased using individual trained ANN for each specie. The proposed system has been successful in identifying the number of days after catching the fish with an accuracy of up to 91%.

    Full Text Available In years 1998-1999 effects of fungicides (azoxystrobin and copper hydroxide, insecticides (etafenproks and pirimicarb and their mixtures on chemical composition and organoleptic quality of fresh, fermented and pickled cucumbers were studied_ To analyses fruits were taken after 7 and 12 days from treatment. Fresh cucumber fruits after 7 days from treatment with investigated pesticides contained less carbohydrates and ascorbic acids and higher level of nitrates in compare to untreated fruits (control. After 12 days from treatment the differences between treated and untreated fruits dissapeared. Cucumber fruits harvested 7 and 12 days after treatment were processed separately. Quality evaluation of fermented and pickled cucumbers was carried out 4 months after processing. In most of cucumber fruits (7 days after treatment with pesticides treated with pesticides empty cavities were found, and not in control (untreated. Number of cavities was highest in fresh and pickled cucumbers treated with mixture of fungicide and insecticide. In case of fermented cucumbers highest number of empty cavities occurred in fruits treated with fungicide azoxystrobin. Cucumber fruits taken to fermentation process 7 days after day of treatment had darker green colour, lowered haIdness, and larger empty cavities than untreated fruits. In fruits harvested 12 days after pesticides application such differencess were not observed.

  12. Selling eugenics: the case of Sweden.

    Science.gov (United States)

    Bjorkman, Maria; Widmalm, Sven

    2010-12-20

    This paper traces the early (1910s to 1920s) development of Swedish eugenics through a study of the social network that promoted it. The eugenics network consisted mainly of academics from a variety of disciplines, but with medicine and biology dominating; connections with German scientists who would later shape Nazi biopolitics were strong. The paper shows how the network used political lobbying (for example, using contacts with academically accomplished MPs) and various media strategies to gain scientific and political support for their cause, where a major goal was the creation of a eugenics institute (which opened in 1922). It also outlines the eugenic vision of the institute's first director, Herman Lundborg. In effect the network, and in particular Lundborg, promoted the view that politics should be guided by eugenics and by a genetically superior elite. The selling of eugenics in Sweden is an example of the co-production of science and social order.

    2000-01-01

    Full Text Available The determination of the price should meet certain criteria, both from the society and the company itself. The combination of various criteria will result in another problem. Fuzzy Logic covers all influencing factors and displays the membership function graphic. Furthermore, by implementing fuzzy rules and fuzzy operator, the right price can be determined which covers all the factors above. The determination of the rules is based on the raw material cost, direct labor cost, distribution cost and the customers' opinion regarding the appropriate price. Then, the model is designed with the help of Matlab software. The result is finally obtained in the form of a model performed by Matlab software. The model displays the output concerning the selling price of the product for each change in the dominant factors.

  14. Modeling switching behaviour of direct selling customers

    Directory of Open Access Journals (Sweden)

    P Msweli-Mbanga

    2004-04-01

    Full Text Available The direct selling industry suffers a high turnover rate of salespeople, resulting in high costs of training new salespeople. Further costs are incurred when broken relationships with customers cause them to switch from one product supplier to another. This study identifies twelve factors that drive the switching behaviour of direct sales customers and examines the extent to which these factors influence switching. Exploratory factor analysis was used to assess the validity of these factors. The factors were represented in a model that posits that an interpersonal relationship between a direct sales person and a customer moderates the relationship between switching behaviour and loyalty. Structural equation modeling was used to test the proposed model. The author then discusses the empirical findings and their managerial implications, providing further avenues for research.

  15. Selling Participation to Audiences in China

    Directory of Open Access Journals (Sweden)

    Kuo Huang

    2009-01-01

    Full Text Available Media globalization is facilitated by the development of new technologies within a framework of digitization and convergence. Contemporary new media provide networks through which the mingling of media occurs, shaping a “multi-mediacy” age, and a connecting of mediated/mediating venues in a condition of “immediacy”. Additionally, the business of communication has evolved from being the “communication of business” to the “business of business”. Multi-mediacy and immediacy have generated new avenues of profit from media. The paper will draw on Chitty’s theorization on web transactional venues to discuss new ways of farming of revenue from media. Media revenues have in the past and today been drawn from licence fees, media subscriptions and advertising. Today, media networks also sell “participation” to audiences directly by charging for text message voting/gaming, or sell a range of products and services through web-venue based commerce. This paper will undertake case studies to examine the increasing trend of “direct audience payment for participation”. The case studies that will be used are (A the intervention of Chinese Service Providers in reality TV shows and (B E-commerce on the Internet. Monternet (mo[bile I]nternet and Linktone are investigated as Service Providers (SPs and the consumer-to-consumer (C2C website www.taobao.com is studied compared with Eachnet (eBay in China. The paper will also investigate the influences of “direct audience payment for participation” on the quality of media products and communication flow between media and audience and generally discuss the consequences of the “direct audience payment for participation” from the perspective of communication ethics.

  16. CHARACTERIZATION OF RIPENING STAGES OF MYRTLE FRUIT

    Directory of Open Access Journals (Sweden)

    DYALLA RIBEIRO DE ARAUJO

    2016-01-01

    Full Text Available ABSTRACT The myrtle (Eugenia gracillima Kiaersk. is a native fruit species in the Chapada of Araripe, state of Pernambuco, Brazil. The fruits are collected from the wild and are consumed fresh or processed as pulp, juice, jelly, liquor or desserts. Myrtle fruit production is of significant socioeconomic value for the region and, therefore, the description of myrtle fruit ripening stages may contribute to the development of its production chain. As a result, the objective of the present study was to evaluate the physical, quality and ripening changes of myrtle fruits at different developmental stages. The fruits were picked at five distinctive stages and evaluated for longitudinal and transverse diameters; fresh, dry and water mass; water contents; soluble solids (SS; titratable acidity (TA; pH; SS/TA ratio; carbohydrates (starch, total, reducing and nonreducing sugars; ascorbic acid; total pectin, soluble pectins and percentage of pectin solubilization; polymeric, oligomeric and dimeric phenolics; total anthocyanins, carotenoids and chlorophyll; and yellow flavonoids. Along fruit ripening processes increases in SS, anthocyanins and carotenoids, in the SS/TA ratio and of percentages of pectin solubilization were determined. On the other hand, decreases in TA and total chlorophyll were observed. The ripening stage at which peel color is completely dark red (ripening stage 4 is most appropriate to harvest myrtle fruits for human consumption.

    Fresh-cut fruit and vegetable are minimally processed products that have to maintain their quality (appearance, texture, flavour and nutritive value) similar to those of the fresh product. The fundamental principle underlying the quality of these commodities is that they are metabolic active tissues and, as a consequence, show physiological response to preparation procedures as well as to the environment created in the package in which they are enclosed. Minimal processing for fresh-cut potat...

    Molina, J. M.; Calvo, D.; Medina, J. J.; Barrau, C.; Romero, E.

    2008-07-01

    Physical and chemical parameters of fresh berries from three southern high bush (ONeal, Sharp blue and Misty) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on physical and chemical characteristics of fruit were due to cultivar. All three cultivars showed significantly different means (P<0.05) for fruit fresh weight, and all chemical characteristics. Stepwise discriminant analysis (SDA) for classification and identification of the cultivars based on physico-chemical properties of samples of fruits was performed. The model obtained gave high percentages of correct classification and prediction (81.1% and 78.4%, respectively). The variables with higher discriminating power were fruit titratable acidity, fruit size and fruit sugar content. (Author)

  3. Option contracts in fresh produce supply chain with circulation loss

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available Purpose: The purpose of this paper is to investigate management decisions via option contracts in a two-stage supply chain in which a fresh produce supplier sells to a retailer, considering the circulation loss of the fresh produce. Design/methodology/approach: Authors propose a Stackelberg model to analyze the supply chain members’ decisions in the decentralized supply chain compared with the integrated one under the newsvendor framework. Findings: The results illustrate that there exists a unique optimal option order quantity for the retailer and a unique optimal option order price for the supplier giving certain conditions; furthermore, option contracts cannot coordinate the fresh produce supply chain when the retailer only orders options. Originality/value: Agricultural products especially fresh produce’s characteristics such as circulation loss and high risk are considered. Option contracts and game theory are combined to manage the fresh produce supply chain’s risk. The proposed tool and models are hoped to shed light to the future works in the field of supply chain risk management.

  15. Effects of solar radiation on grape (Vitis vinifera L.) composition and dried fruit colour

    International Nuclear Information System (INIS)

    Uhlig, B.A.

    1998-01-01

    Most sun-exposed fruit (Vitis vinifera L.) produced dark brown berries with low L-values, whereas most dried berries from shade fruit were acceptable in lightness although some had a green tinge. Fruit shaded by the natural vine canopy or exposed to direct solar radiation had similar drying ratios. However, berry weights were significantly higher in the shade than in the sun for both cultivars. The difference in berry weight between the two positions was less pronounced in the heat affected year. Solar radiation changed the composition of fresh berries and the colour of the dried fruit. The soluble-solid concentration was higher in fresh fruit exposed to direct solar radiation than in fruit grown in shaded conditions within the canopy. In the heat affected year the berries from both positions had the same soluble-solid concentrations, possibly due to dehydration of the fruit. No significant difference was found between the pH of sun fruit and shade fruit, but the titratable acidity was higher in shade fruit. Malate and tartrate concentrations in berry skin and the polyphenol oxidase activities had carotenoid concentrations in whole fresh berries were not significantly different for sun and shade fruit. Total phenol concentrations in berry skin were higher in sun fruit and chlorophyll concentrations in whole, fresh berries were higher in shade fruit. (author)

    Jehiel, P.; Moldovanu, B.; Stacchetti, E.

    1994-01-01

    We study the problem of a seller who wants to maximize her revenue in situations where the outcome of the sale affects the nature of the future interaction between agents. We model those situations by assuming that an agent that does not acquire the object for sale incurs an externality that may depend both on the identity of the sufferer and on the identity of the final purchaser. We describe an optimal auction that has a unique Nash equilibrium in strictly dominant strategies. We show that: 1) Outside options are endogenously determined in equilibrium. Participation constraints and the ''threats'' in case of non-participation play an important role. 2) An optimizing seller can extract surplus also from buyers that do not obtain the auctioned object. 3) The seller is better off by not selling at all (while obtaining some payments) if externalities are large when compared to the pure profits that buyers achieve if they acquire the object. 4) The revenue-maximizing equilibrium is coalition-proof if buyers cannot organize side payments among themselves.

    Fruits serve as a source of energy, vitamins, minerals, and dietary fiber. One of the barriers in increasing fruit and vegetables consumption is time required to prepare them. Overall, fruit bars have a far greater nutritional value than the fresh fruits because all nutrients are concentrated and, therefore, would be a convenience food assortment to benefit from the health benefits of fruits. The consumers prefer fruit bars that are more tasted followed by proper textural features that could be obtained by establishing the equilibrium of ingredients, the proper choosing of manufacturing stages and the control of the product final moisture content. Fruit bar preparations may include a mixture of pulps, fresh or dried fruit, sugar, binders, and a variety of minor ingredients. Additionally to the conventional steps of manufacturing (pulping, homogenizing, heating, concentrating, and drying) there have been proposed the use of gelled fruit matrices, dried gels or sponges, and extruders as new trends for processing fruit bars. Different single-type dehydration or combined methods include, in order of increasing process time, air-infrared, vacuum and vacuum-microwave drying convective-solar drying, convective drying, and freeze drying are also suggested as alternative to solar traditional drying stage. The dehydration methods that use vacuum exhibited not only higher retention of antioxidants but also better color, texture, and rehydration capacity. Antioxidant activity resulting from the presence of phenolic compounds in the bars is well established. Besides this, fruit bars are also important sources of carbohydrates and minerals. Given the wide range of bioactive factors in fresh fruits that are preserved in fruit bars, it is plausible that their uptake consumption have a positive effect in reducing the risk of many diseases.

    Demand variability is prevailing in the current rapidly changing business environment, which makes it difficult for a retailer that sells multiple substitutable products to determine the optimal inventory. To combat demand uncertainty, both strategies of inventory substitution and probabilistic selling can be used. Although the two strategies differ in operation, we believe that they share a common feature in combating demand uncertainty by encouraging some customers to give up some specific ...

    Occasionally, in China, marine products can not be provided for the markets in good quality, for during the time when they are being transported from the sea port to inland towns or even at the time when they are unloaded from the ship, they are beginning to spoil. Obviously, it is very important that appropriate measures should be taken to prevent them from decay. Our study has proved that the shelf life of fresh Flatfish (Cynoglossue robustus) and Silvery pomfret (stromateoides argenteus), which, packed in sealed containers, are irradiated by 1.5 kGy, 2.2 kGy and 3.0 kGy, can be stored for about 13 to 26 days at 3 deg to 5 deg C.

    1984-01-01

    Irradiation is gaining ground as a food preservation technique in Canada. Some fears remain among members of the public about the safety of irradiated foods, but government standards are being met. Two radiation sources can be used in food irradiation: gamma radiation from a cobalt 60 source, or electrons from an accelerator. The radiation affects the DNA of cells within food such as potatoes, preventing sprouting. It also causes changes within lipids, producing an undesirable rancid flavour. As a result, radiation processing is used primarily on fruits, vegetables, cereals and lean meats. The dose required for preservation is around 0.3 kGy, but higher doses are required for sterilization: 1 to 10 kGy, or even as high as 50 kGy for complete sterilization

    2017-12-12

    To encourage the consumption of more fresh fruits and vegetables, the 2014 United Sates Farm Bill allocated funds to the Double Up Food Bucks Program. This program provided Supplemental Nutrition Assistance Program beneficiaries who spent $10 on fresh fruits and vegetables, in one transaction, with a $10 gift card exclusively for Michigan grown fresh fruits and vegetables. This study analyzes how fruit and vegetable expenditures, expenditure shares, variety and purchase decisions were affected by the initiation and conclusion, as well as any persistent effects of the program. Changes in fruit and vegetable purchase behaviors due to Double Up Food Bucks in a supermarket serving a low-income, predominantly Hispanic community in Detroit, Michigan were evaluated using a difference in difference fixed effects estimation strategy. We find that the Double Up Food Bucks program increased vegetable expenditures, fruit and vegetable expenditure shares, and variety of fruits and vegetables purchased but the effects were modest and not sustainable without the financial incentive. Fruit expenditures and the fruit and vegetable purchase decision were unaffected by the program. This study provides valuable insight on how a nutrition program influences a low-income, urban, Hispanic community's fruit and vegetable purchase behavior. Policy recommendations include either removing or lowering the purchase hurdle for incentive eligibility and dropping the Michigan grown requirement to better align with the customers' preferences for fresh fruits and vegetables.

    Full Text Available In the last 30 years world population has increased 70% but per capita global fruit consumption is only 20% higher. Even though tropical and temperate fruit have similar contributions to the 50 kg/person/year of US consumption of fresh fruit, in the last 30 years this has been slightly greater for temperate fruit. Within fruit consumption, the largest expansion has been for organic fruit which increased more than 50% in the 2002-2006 period. The largest expansion of area planted in the 1996-2006 has been for kiwi (29% and blueberries (20%, while apples (-24% and sour cherries (-13% have had the largest reductions. Nearly 50% of the total global volume of fruit is produced by 5 countries: China, USA, Brazil, Italy and Spain. The main producer (China accounts for 23% of the total. While the main exporters are Spain, USA and Italy, the main importers are Germany, Russia and UK. Demands for the industry have evolved towards quality, food safety and traceability. The industry faces higher productions costs (labor, energy, agrichemicals. The retailers are moving towards consolidation while the customers are changing preferences (food for health. In this context there is greater pressure on growers, processors and retailers. Emerging issues are labor supply, climate change, water availability and sustainability. Recent developments in precision agriculture, molecular biology, phenomics, crop modelling and post harvest physiology should increase yields and quality, and reduce costs for temperate fruit production around the world.

    Full Text Available The paper discusses the renewed short selling regulation (Regulation (EU No 236/2012 in the European Union. The focus is on the provisions that deal with prohibiting short selling in exceptional market circumstances. The Regulation further enforces certain obligations to report and disclose short positions. It is concluded that banning short selling is not an effective tool to contain extreme price volatility. The difference-in-differences regression and repeated measures GLM were used to test whether short selling bans were successful in containing volatility of those Spanish and Italian stocks that were subject to two back-to-back prohibitions during the years 2011-2013. The results are consistent with the majority of previous research, suggesting that the effectiveness of short sale constraints in reducing volatility is limited at best. Furthermore, there are evidence of counterproductive effects: constraints on short selling may actually increase volatility as well as deteriorate liquidity. However, based on theory and previous studies, reporting and disclosure requirements shall be favored provided they improve market efficiency as well as supervisory work of regulatory bodies.This paper discusses the renewed short selling regulation (Regulation (EU No 236/2012 in the European Union.

    To make dried-fruits of persimmon (Diospyros kaki), its fresh fruits were generally processed to decrease their water-contents to about 30-50%. During this food process, their radiocaesium concentrations increased without any loss, and, occasionally, the dried-fruits may exceed the food standard level of 100 Bq/kg (edible form). Thus, it is necessary to estimate the radiocaesium concentrations in the products before the fresh fruit harvesting and processing. For this purpose, radiocaesium concentrations in leaves of persimmon trees were monitored with time. The 137 Cs concentrations in the fruits were usually lower than those in the leaves and the concentration ratio was less than 0.4 on a fresh weight basis. The ratio became smaller when closer the harvest season. Thus the concentration of leaves could be a good indicator to estimate the processed persimmon fruits. (author)

    Full Text Available The market sales of ready to use fresh cut fruits have grown rapidly in recent decades. Kiwi fruit is an important fruit that its marketing as fresh cut has increased in recent years. The main limiting factors in shelf life of fresh cut fruits are microbial spoilage, drastic softening and browning. In this study, the effects of oxalic and citric acids, both at 0, 2, 4 and 6 mM concentrations, with or without ultra-sonic treatment were investigated on the increasing the shelf life of fresh cut kiwi fruit. After treatments, the fresh slices were stored at 2°C for 7 or 14 days and assessed for several traits and analyzed. Results showed that, oxalic and citric acid treated slices, in comparison to the control, had greater marketability, as well as higher flesh firmness, titrable acidity, ascorbic acid content, total phenol content and antioxidant capacity and smaller bacterial forming colony unit (CFU. Among the treatments, 2, 4 and 6 mM oxalic acid and 6 mM citric acid treatments were found more appropriate than the reaming treatments. Application of ultra-sonic treatment, despite the reduction of microbial load and maintaining antioxidant capacity, had no effects on marketability of fresh cut kiwi fruit. Hence, application of organic acid treatments as dipping can be used to increase the shelf life of fresh cut kiwi fruit.

    2004-04-01

    We have studied the purine alkaloid content and purine metabolism in Theobroma cacao fruits at differing growth stages: Stage A (young small fruit, fresh weight, ca. 2 g); stage B (medium size fruit, fresh weight, ca. 100 g) and stage C (large size, fresh weight, ca. 500 g). The major purine alkaloid in stage A fruits (mainly pericarp) was theobromine (0.7 micromol g(-1) fresh weight), followed by caffeine (0.09 micromol g(-1) fresh weight). The theobromine content of the pericarp decreased sharply with tissue age, and the caffeine content decreased gradually. A large amount of theobromine (22 micromol g(-1) fresh weight) had accumulated in seeds (mainly cotyledons) of stage C fruits. Theobromine was found also in the seed coat and placenta. Tracer experiments with [8-(14)C]adenine show that the major sites of theobromine synthesis are the young pericarp and cotyledons of T. cacao fruits. Limited amounts of purine alkaloids may be transported from the pericarp to seed tissue, but most purine alkaloids that accumulated in seeds appeared to be synthesised in cotyledons. Degradation of [8-(14)C]theobromine and [8-(14)C]caffeine to CO2 via 3-methylxanthine and ureides (allantoin and allantoic acid) was detected only in the pericarp of stage C fruits.

The aim was to gain an understanding of young women’s perceptions of the reasons they started, continued, and stopped selling sex. The study included interviews with 15 young women between the ages of 15 and 25 (M=18.9. Thematic analysis was used to identify similarities and differences in the narratives. Three themes and eight sub-themes were identified in relation to different stages in their lives in the sex trade. The themes were organized into three parts, each with its own storyline: “Entering – adverse life experiences”; traumatic events: feeling different and being excluded. “Immersion – using the body as a tool for regulating feelings”; being seen: being touched: being in control: affect regulation and self-harming. “Exiting – change or die”; living close to death: the process of quitting. The informants all had stable social lives in the sense that they had roofs over their heads, food to eat, and no substance-abuse issues. None had a third party who arranged the sexual contacts and none were currently trafficked. They described how their experiences of traumatic events and of feeling different and excluded had led them into the sex trade. Selling sex functioned as a way to be seen, to handle traumatic events, and to regulate feelings. Professionals working with young people who sell sex online need to understand the complex web of mixed feelings and emotional needs that can play a role in selling sex. Young people selling sex might need guidance in relationship building as well as help

    Studies were made to establish standard conditions for mutation induction by gamma-irradiation to be performed in combination with in-vitro culture for banana and citrus spp. Besides this, radio-sensitivity of seeds and/or plantlets of mango, sugar apple, soursop, lanzones and Jack fruit was investigated and primary observation on the occurrence of mutation was made. For the mutagenesis of banana shoot tip cultures, radio-sensitivity of plantlets derived from the culture as well as fresh-cultured shoots was examined and phenotypes indicative of mutation, such as chlorophyl streaking, slow growth, pigmentation and varied bunch orientation were recorded. Isozyme analysis for mutated protein structure was not conclusive. In the in-vitro culture of Citrus spp., seeds placed on fresh media as well as germinating seeds and two-leaf stage seedlings in test tubes were examined for their radio-sensitivity. Irradiated materials were propagated for further observation. In these two crops, basic methodology for mutation induction with combined use of in-vitro culture and gamma-irradiation was established. In mango, sugar apple, soursop, lanzones and Jack fruit, basic data on radiosensitivity were obtained. In mango, leaf abnormalities were observed after the treatment of scions

    This study assesses the availability of websites offering to sell psilocybin spores and psilocybin, a powerful hallucinogen contained in Psilocybe mushrooms. Over a 25-month period beginning in March 2003, eight searches were conducted in Google using the term "psilocybin spores." In each search the first 100 nonsponsored links obtained were scored by two independent raters according to standardized criteria to determine whether they offered to sell psilocybin or psilocybin spores. No attempts were made to procure the products offered for sale in order to ascertain whether the marketed psilocybin was in fact "genuine" or "counterfeit." Of the 800 links examined, 58% led to websites offering to sell psilocybin spores. Additionally, evidence that whole Psilocybe mushrooms are offered for sale online was obtained. Psilocybin and psilocybin spores were found to be widely available for sale over the Internet. Online purchase of psilocybin may facilitate illicit use of this potent psychoactive substance. Additional studies are needed to assess whether websites offering to sell psilocybin and psilocybin spores actually deliver their products as advertised.

    Full Text Available This paper reports about the content of polyphenols and volatiles in fresh fruits of two sour cherry cultivars (Marasca and Oblačinska, some berry fruits (strawberry Maya, raspberry Willamette and wild blueberry and the corresponding low sugar jams. Phenolic compounds (hydroxybenzoic and hydroxycinnamic acids, flavan 3-ols and flavonols were determined by high-performance liquid chromatography (HPLC. Those found in the fruits were also found in the jams. Jams contained lower amounts of polyphenols than fresh fuits, but their overall retention in jams was relatively high. Among fruits, sour cherry Marasca had the highest level of polyphenols, while sour cherry Marasca jam and raspberry Willamette jam had the highest level of polyphenols among jams. The major flavonoid in all investigated fruits, except in sour cherry Oblačinska, was (–-epicatechin. Sour cherry Marasca had the highest level of (–-epicatechin (95.75 mg/kg, and it also contained very high amounts of flavonols, derivatives of quercetin and kaempferol. Hydroxybenzoic acids (HBAs were not found in sour cherries Marasca and Oblačinska, but were found in berry fruits and jams. Phenolic compound (+-gallocatechin was found only in Marasca fruit and jam. Ellagic acid was found in the highest concentration in raspberry Willamette fruit and jam. Hydroxycinnamic acids (HCAs were found in all the investigated fruits, with the exception of a derivative of ferulic acid, which was not found in strawberry. Derivatives of caffeic, p-coumaric and chlorogenic acids were found in all the investigated fruits, with chlorogenic acid being the most abundant, especially in sour cherry Marasca. Volatiles were determined by gas chromatography (GC and expressed as the peak area of the identified compounds. All investigated volatiles of fresh fruit were also determined in the related jams with relatively high retention. Sour cherries Marasca and Oblačinska contained the same volatile compounds, but

    Full Text Available Purpose: The purpose of this paper is to help business marketers with offline channels to make decisions on whether to sell through Group-buying (GB websites and how to set online price with the coordination of maximum deal size on GB websites. Design/methodology/approach: Considering the deal structure of GB websites especially for the service fee and minimum deal size limit required by GB websites, advertising effect of selling on GB websites, and interaction between online and offline markets, an analytical model is built to derive optimal online price and maximum deal size for sellers selling through GB website. This paper aims to answer four research questions: (1 How to make a decision on maximum deal size with coordination of the deal price? (2 Will selling on GB websites always be better than staying with offline channel only? (3 What kind of products is more appropriate to sell on GB website? (4How could GB website operator induce sellers to offer deep discount in GB deals? Findings and Originality/value: This paper obtains optimal strategies for sellers selling on GB website and finds that: Even if a seller has sufficient capacity, he/she may still set a maximum deal size on the GB deal to take advantage of Advertisement with Limited Availability (ALA effect; Selling through GB website may not bring a higher profit than selling only through offline channel when a GB site only has a small consumer base and/or if there is a big overlap between the online and offline markets; Low margin products are more suitable for being sold online with ALA strategies (LP-ALA or HP-ALA than high margin ones; A GB site operator could set a small minimum deal size to induce deep discounts from the sellers selling through GB deals. Research limitations/implications: The present study assumed that the demand function is determinate and linear. It will be interesting to study how stochastic demand and a more general demand function affect the optimal

    The present study was carried out in order to detect the irradiated fruits and assess the quality parameters of plums (Prunus domestica L., cv. Pioneer) and peaches (Prunus persica Bausch, cv. Swilling) fruits treated with gamma irradiation. This investigation was carried out during 2010 and 2011 seasons. The fruits were harvested at commercial maturity, irradiated with the doses 0.50, 0.75 and 1.0 kGy, stored under refrigerated conditions (0±1°C, RH 80%) then evaluated at intervals of 7, 10 and 21 days (the end cold storage period) followed by 5 days of storage under market condition (20±2°C, RH 80%). Electron spin resonance (ESR) was carried out for determination of free radicals by using dried layers of plum and peach kernels. Fruit characters included weight loss %, fruit firmness (kgf), discarded fruits %, soluble solid contents (SSC, ºBrix), total titratable acidity (TA%), respiration rate and sensory evaluation tastes. ESR results proved the possibility of identification of irradiated fruits by using dried stone kernels. The results showed that ESR intensities were sensitive for all applied doses even at low doses of 0.5 or 1.0 kGy which was applied for dis infestations, to extend the shelf-life of fruits or to detect the irradiated stored fresh samples was carried out at the 7th, 10th and 21st days. The linear relationship resulted between ESR intensity and applied doses showed high significant correlation coefficient (R2) for the irradiated samples. However, ESR intensity was decreased gradually during long storage period but can identify clearly the irradiated samples. Irradiation treatment at 0.5 kGy for P ioneer p lums and at 0.5 or 0.75 kGy for S willing p eaches was effective in slowing the rate of losing of fruits weight and decreasing the discarded fruits percentage. Furthermore, it has significant effects on reducing respiration rate, maintaining higher soluble solid contents and decreasing total titratable acidity. Referring to sensory

    The columnar cactus Cereus peruvianus (L.) Miller, Cactaceae (koubo), is grown commercially in Israel. The unripe fruits are green, and the color changes to violet and then to red when the fruit is fully ripe. The content of soluble sugars was found to increase 5-fold during ripening. Glucose and fructose were the main sugars accumulated in the fruit pulp, and each increased from 0.5 to 5.5 g/100 g fresh weight during ripening. The polysaccharides content decreased during ripening from 1.4 to 0.4 g/100 g fresh weight. The titratable acidity decreased and the pH increased during ripening. The major organic acid found in the fruit was malic acid, which decreased from 0.75 g/100 g fresh weight at the mature green stage to 0.355 g/100 g fresh weight in ripe fruits. Citric, succinic, and oxalic acids were found in concentrations lower than 0.07 g/100 g fresh weight. Prominent accumulation of aroma volatiles occurred toward the end of the ripening process. The main volatile found in the ripe fruit was linalool, reaching concentrations of 1.5-3.5 microg/g fresh weight.

  1. A comparative study of the effect on irradiation and chemical preservatives on fresh-cut mangoes

    2011-01-01

    The quest for ready-to-eat fruits has resulted in cut-fruits such as pawpaw, watermelon and pineapple in the local market. However the safety and quality these products cannot be guaranteed due to the mode of preparation and packaging. Mango (Mangifera indica L.) fruits are consumed, among other reasons, for their pleasant flavour. They are rich sources of vitamins A, B6 and C. Mango fruits are being increasingly processed into ready-to-eat products such as fresh-cut mango slices. These products have longer shelf life when properly preserved and, therefore, assure all year round availability of mango in different forms. In order to produce fresh-cut mango slices of acceptable quality, determination of the most appropriate stage of ripening of fruits for fresh-cut slices production should be known. This study determined the effects of irradiation and chemical preservatives on the safety and shelf life quality of fresh-cut mango products. The effects of gamma irradiation and chemical preservatives on physicochemical, microbiological and sensory qualities of fresh-cut mango products were evaluated. Questionnaires were administered to evaluate public perception of cut-fruits and irradiated foods. Well matured half-ripe with peel of green and a little yellow intact fruits were sampled for laboratory analysis using 2x2x5 factorial experiment. The fruits were sanitized, peeled and sliced into cubes and packaged in two sets of 30 PET jars. One set was subjected to various radiation dose levels (1.0, 1.5, 2.0 and 2.5) kGy and a control. The second set was chemically preserved with various chemicals (sucrose, citric acid, sodium benzoate and a combination of these chemicals in equal proportions. The treated cut-mangoes were stored at 6 degrees Celsius and 10 degrees Celsius for 15 days and samples taken at 3 days interval for analysis. The pH, titratable acidity (TTA), vitamins C content, total soluble solids (TSS), microbial quality and sensory evaluations were carried out

    Full Text Available This paper addresses the issue of the understanding of the book-selling situation as Swedish booksellers see it. It pursues the answers to the following questions: 1. What are the perceptions of Swedish booksellers of the impact of e-books on their business? 2. What drivers are important for Swedish booksellers for adopting and developing e-book sales through their own sales channels? 3. What do they perceive as barriers to e-book selling through their own channels? The authors have employed the analysis of the secondary statistical data and a survey of Swedish booksellers to answer their questions. The results of the investigation have shown that the Swedish booksellers do not feel their bookshops, or business in general, are threatened by e-books. The opinions on e-books do not differ between the few selling e-books and others who do not offer this product. The reasons for selling e-books are well-functioning routines and personal interest in the product. The reasons for not selling the books are the lack of demand and technical resources as well as contractual agreements with e-book publishers or vendors. So, technical resources for e-book sales, routines, and contracts with publishers are the main premises for this activity. The biggest barriers to e-book sales are: a the price as one can see not only in the answers of the booksellers, but also in the drop of sales obviously related to the rise of prices during 2014; b lack of demand from customers who do not enquire about e-books in bookshops. This leads to the belief that e-books will be sold mostly online either directly from publishers and authors or through online booksellers. However, an equal number of booksellers believe that physical bookshops will be selling printed books and e-books in the future. The future of e-books seems to be quite secure and non-threatening to printed books from the point of view of booksellers. The growth of e-book sales is quite slow and the respondents

    To investigate a 9-year trend of fresh fruit and vegetable availability and factors associated with the net availability change in two contrasting neighbourhoods. Longitudinal design. Data were collected in 2003, 2009 and 2012 through in-store observations. Fresh fruit and vegetable availability was presented by weight-adjusted counts of stores having designated varieties per 10 000 population. A low-income minority neighbourhood and an adjacent middle-income racially mixed neighbourhood in Albany, NY, USA. These neighbourhoods became sites of fresh produce interventions after baseline data were collected. A total of 111, 128 and 146 eligible food stores in respective years. Fresh fruit availability (two or more varieties) increased in both neighbourhoods. Inventory expansion of existing stores and the convenience store intervention contributed to the significant increase (P for trend=0·04) of fresh fruit availability in the minority neighbourhood. Although not statistically significant (P>0·05), the availability of two or more dark-coloured fresh vegetables also increased in the mixed neighbourhood, but declined slightly in the minority neighbourhood. The secular (non-intervention) fresh vegetable availability rate ratio by neighbourhood reached 3·0 in 2012 (Pconvenience store intervention to address the fresh vegetable disparity.

  11. Microbiology of organic and conventionally grown fresh produce

    Directory of Open Access Journals (Sweden)

    Daniele F. Maffei

    Full Text Available ABSTRACT Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues of agrochemicals. Organic farming practices such as the use of animal manure can however increase the risk of contamination by enteric pathogenic microorganisms and may consequently pose health risks. A number of scientific studies conducted in different countries have compared the microbiological quality of produce samples from organic and conventional production and results are contradictory. While some have reported greater microbial counts in fresh produce from organic production, other studies do not. This manuscript provides a brief review of the current knowledge and summarizes data on the occurrence of pathogenic microorganisms in vegetables from organic production.

    Full Text Available Sicily has become a food and wine area of great interest. However, conflicts within the supply chains have caused the selling process to become long and complex to the disadvantage of farmers, thereby leading to an information asymmetry between producers and consumers.In order to meet the new needs of the agrifood sector, we developed a theoretical model of organized direct selling that goes beyond regional boundaries, which is an alternative model to farmers’ markets and that helps to promote the creation of a network among the operators of Sicilian agrifood supply chains. The aims of this study was to verify the potential of the proposed theoretical model based on a SWOT analysis, which was achieved by collecting data from interviews with the producers involved in the Sicilian agrifood supply chains, and with the main stakeholders involved.

This is a modified Classification and Regression Trees (CART) used to help decide which question(s) to ask potential applicants to customise an offer of a personal financial product so that it would have a high probability of take up. In this piece of work the authors are presenting, they have further modified the TAROT to cross TAROT, using its properties and modeling steps to deal with the issue of cross-selling. Since the bank already has ready customers, it would be ideal to cross-sell the financial products seeing that one can ask one (or more) further question(s) based on the initial offer to identify and customise another financial product to offer.

    Full Text Available Environmental conservation concerns have led to research and development regarding biodegradable materials from biopolymers, leading to new formulations for edible films and coatings for preserving the quality of fresh fruit and vegetables. Determining fruit skin surface properties for a given coating solution has led to predicting coating efficiency. Wetting was studied by considering spreading, adhesion and cohesion and measuring the contact angle, thus optimising the coating formulation in terms of biopolymer, plasticiser, surfactant, antimicrobial and antioxidant concentration. This work reviews the equations for determining fruit surface properties by using polar and dispersive interaction calculations and by determining the contact angle.

  20. Group Buying: A New Mechanism for Selling Through Social Interactions

    OpenAIRE

    2011-01-01

    This paper examines a unique selling strategy, Group Buying, under which consumers enjoy a discounted group price if they are willing and able to achieve a required group size and coordinate their transaction time. We argue that Group Buying allows a seller to gain from facilitating consumer social interaction, i.e., using a group discount to motivate informed customers to work as "sales agents" to acquire less-informed customers through interpersonal information/knowledge sharing. We formall...

    Recent evidence suggests that one-third of women receive information about pregnancy and childbirth through books. Messages about what characteristics are normal (or expected) in childbirth are disseminated in a variety of ways, including popular childbirth education books, but little study of them has been conducted. The purpose of this investigation is to address that gap by examining the discussions about childbirth in the 10 top-selling books in the United States. Discourse analysis (relating to the public, personal, and political discussions about a specific phenomenon) was used to study 10 best-selling United States childbirth advice books marketed to childbearing women during the first week of November 2007. Book styles ranged from clinical descriptions of pregnancy and birth primarily offering reassurance, self-help information, and danger signs to more folksy and humorous commentaries. Presentation of scientific evidence to support recommendations was uneven and at times inaccurate. Five focal areas of discourse included body image, labor and birth, pain, power and control, and life preparation for motherhood. Top-selling books shine an interesting light on the current state of United States maternity practices. Women and health professionals should assess them carefully and engage with each other about their recommendations and implications for childbirth.

    Improving the quality of different fresh-cut fruits by adding natural substances was studied. "Fuji" apples, "Flor de Invierno" pears, and "Piel de Sapo" melons were treated with calcium lactate, N-acetyl-L-cysteine, glutathione, and malic acid and stored for 4 wk at 4 degrees C. Instrumental texture (penetration), microstructure (light microscopy), acidity, soluble solids, color, pectinmethylesterase activity, and microflora were studied. The results showed that the combined treatment reinforced the cell walls strengthening the structure and texture of these fruits and maintained the L* and a* values throughout 4 wk of storage at 4 degrees C. The combination of additives provided low microbial counts in apples until the 4th week and in melons until the 2nd week. So, this combined treatment could be used to extend the shelf life of some fresh-cut fruits while preserving their quality.

    Chitosan coating plus different essential oils was developed and applied to fresh blueberries in order to find more natural treatments to preserve fresh fruit quality and safety during postharvest storage. Studies were 1st performed in vitro where wild-type Escherichia coli and Penicillium digitatum were grown in suitable media, and then subjected to 6 essential oils. Three compounds, carvacrol (CAR), cinnamaldehyde (CIN), and trans-cinnamaldehyde (ECIN) had high antimicrobial capacity and were selected for an in vivo study for postharvest storage of blueberries. The selected essential oils, 0.5% each, were added into a chitosan solution and coated on fresh blueberries. After storage at 5, 10, and 20 °C for various days, fruit firmness and microbial populations were evaluated. The chitosan coating substantially decreased bacteria and yeasts/molds on the fruit, and all 3 essential oils added to the antimicrobial activities. Further dosage experiments showed that the antimicrobial activity remained even when lowering CAR concentration to 0.1% and ECIN to 0.2%. Chitosan, CAR, and ECIN also maintained fruit firmness. Our results suggest that chitosan coatings containing essential oils are effective in extending the shelf life of fresh blueberries. Blueberries are high-value fruit with strong antioxidant capacity and other health-promoting benefits. However, microbial food safety is an increasing concern, and decay and softening limits their storability. A combination of ≥ 0.1% CAR or ≥ 0.2% ECIN with a chitosan coating effectively reduced softening of fresh berries and decay by inhibiting microbial growth. © 2014 Institute of Food Technologists®

    The star fruit belongs to the family Oxalidacea, species Averrhoa carambola. It is rich in minerals, vitamin A, C, B complex vitamins and oxalic acid. Recent studies show that the toxicity of the fruit differs between the patients and may be explained by single biological responses, age, and the intake quantity of the neurotoxin in each fruit in addition to glomerular filtration rate given by each patient. Additionally, the nephrotoxicity caused by the fruit is dose-dependent and may lead to the deposition of crystals of calcium oxalate intratubular, as well as by direct injury to the renal tubular epithelium, leading to apoptosis of the same. We report the case of a patient who after ingestion of the juice and fresh fruit, developed acute renal failure requiring dialysis, evolving with favourable outcome and recovery of renal function.

    In this concluding article in the series on the technological feasibility of ionizing radiation treatment for shelf life improvement of fruits and vegetables, the present status of research on several commodities that have not been dealt with earlier is discussed. The commodities include mushrooms, tomatoes, pineapples, lychees, longans, rambutans, mangostenes, guavas, sapotas, loquats, ber, soursops, passion fruits, persimmons, figs, melons, cucumbers, aubergines, globe artichokes, endives, lettuce, ginger, carrots, beet roots, turnips, olives, dates, chestnuts, almonds, pistachios, and other dried fruits and nuts. Changes induced by irradiation on metabolism, chemical constituents, and organoleptic qualities are considered while evaluating the shelf life. The commodities have been grouped into those showing potential benefits and those not showing any clear advantages from radiation treatment. Shelf life improvement of mushrooms and insect disinfestation in dried fruits, nuts, and certain fresh fruits appears to have immediate potential for commercial application. 194 references

    Fruiting structures in the angiosperms range from completely dry to highly fleshy organs and provide many of our major crop products, including grains. In the model plant Arabidopsis, which has dry fruits, a high-level regulatory network of transcription factors controlling fruit development has been revealed. Studies on rare nonripening mutations in tomato, a model for fleshy fruits, have provided new insights into the networks responsible for the control of ripening. It is apparent that there are strong similarities between dry and fleshy fruits in the molecular circuits governing development and maturation. Translation of information from tomato to other fleshy-fruited species indicates that regulatory networks are conserved across a wide spectrum of angiosperm fruit morphologies. Fruits are an essential part of the human diet, and recent developments in the sequencing of angiosperm genomes have provided the foundation for a step change in crop improvement through the understanding and harnessing of genome-wide genetic and epigenetic variation.

    Dried fruits products present different market values according to their quality. Such a quality is usually quantified in terms of freshness of the products, as well as presence of contaminants (pieces of shell, husk, and small stones), defects, mould and decays. The combination of these parameters, in terms of relative presence, represent a fundamental set of attributes conditioning dried fruits humans-senses-detectable-attributes (visual appearance, organolectic properties, etc.) and their overall quality in terms of marketable products. Sorting-selection strategies exist but sometimes they fail when a higher degree of detection is required especially if addressed to discriminate between dried fruits of relatively small dimensions and when aiming to perform an "early detection" of pathogen agents responsible of future moulds and decays development. Surface characteristics of dried fruits can be investigated by hyperspectral imaging (HSI). In this paper, specific and "ad hoc" applications addressed to propose quality detection logics, adopting a hyperspectral imaging (HSI) based approach, are described, compared and critically evaluated. Reflectance spectra of selected dried fruits (hazelnuts) of different quality and characterized by the presence of different contaminants and defects have been acquired by a laboratory device equipped with two HSI systems working in two different spectral ranges: visible-near infrared field (400-1000 nm) and near infrared field (1000-1700 nm). The spectra have been processed and results evaluated adopting both a simple and fast wavelength band ratio approach and a more sophisticated classification logic based on principal component (PCA) analysis.

    Full Text Available The effects of freeze-drying on antioxidant compounds and antioxidant activity of five tropical fruits, namely starfruit (Averrhoa carambola L., mango (Mangifera indica L., papaya (Carica papaya L., muskmelon (Cucumis melo L., and watermelon Citruluss lanatus (Thunb. were investigated. Significant (p < 0.05 differences, for the amounts of total phenolic compounds (TPC, were found between the fresh and freeze-dried fruit samples, except muskmelon. There was no significant (p > 0.05 change, however, observed in the ascorbic acid content of the fresh and freeze-dried fruits. Similarly, freeze-drying did not exert any considerable effect on β-carotene concentration of fruits, except for mango and watermelon, where significantly (p < 0.05 higher levels were detected in the fresh samples. The results of DPPH (2,2-diphenyl-1-picrylhydrazyl radical scavenging and reducing power assays revealed that fresh samples of starfruit and mango had relatively higher antioxidant activity. In case of linoleic acid peroxidation inhibition measurement, a significant (p < 0.05 but random variation was recorded between the fresh and freeze-dried fruits. Overall, in comparison to β-carotene and ascorbic acid, a good correlation was established between the result of TPC and antioxidant assays, indicating that phenolics might have been the dominant compounds contributing towards the antioxidant activity of the fruits tested.

    The effects of partial root-zone drying (PRD) on tomato fruit growth and proteome in the pericarp of cultivar Ailsa Craig were investigated. The PRD treatment was 70% of water applied to fully irrigated (FI) plants. PRD reduced the fruit number and slightly increased the fruit diameter, whereas the total fruit fresh weight (FW) and dry weight (DW) per plant did not change. Although the growth rate was higher in FI than in PRD fruits, the longer period of cell expansion resulted in bigger PRD fruits. Proteins were extracted from pericarp tissue at two fruit growth stages (15 and 30 days post-anthesis [dpa]), and submitted to proteomic analysis including two-dimensional gel electrophoresis and mass spectrometry for identification. Proteins related to carbon and amino acid metabolism indicated that slower metabolic flux in PRD fruits may be the cause of a slower growth rate compared to FI fruits. The increase in expression of the proteins related to cell wall, energy, and stress defense could allow PRD fruits to increase the duration of fruit growth compared to FI fruits. Upregulation of some of the antioxidative enzymes during the cell expansion phase of PRD fruits appears to be related to their role in protecting fruits against the mild stress induced by PRD.

    Tropical fruit crops are predominantly produced in tropical and subtropical developing countries, but some are now grown in southern Japan. Pineapple (Ananas comosus), mango (Mangifera indica) and papaya (Carica papaya) are major tropical fruits cultivated in Japan. Modern, well-organized breeding systems have not yet been developed for most tropical fruit species. Most parts of Japan are in the temperate climate zone, but some southern areas such as the Ryukyu Islands, which stretch from Kyushu to Taiwan, are at the northern limits for tropical fruit production without artificial heating. In this review, we describe the current status of tropical fruit breeding, genetics, genomics, and biotechnology of three main tropical fruits (pineapple, mango, and papaya) that are cultivated and consumed in Japan. More than ten new elite cultivars of pineapple have been released with improved fruit quality and suitability for consumption as fresh fruit. New challenges and perspectives for obtaining high fruit quality are discussed in the context of breeding programs for pineapple. PMID:27069392

    2010-01-01

    We present a method to incorporate dishonesty in online selling via a stochastic optimal control problem. In our framework, the seller wishes to maximize her average wealth level W at a fixed time T of her choosing. The corresponding Hamilton-Jacobi-Bellmann (HJB) equation is analyzed for a basic case. For more general models, the admissible control set is restricted to a jump process that switches between extreme values. We propose a new approach, where the optimal control problem is reduced to a multivariable optimization problem.

    2012-04-01

    Full Text Available This paper describes the approach taken to present the information on fruits in the IAEA report TRS No. 472, supported by the IAEA-TECDOC-1616, which describes the key transfer processes, concepts and conceptual models regarded as important for dose assessment, as well as relevant parameters for modelling radionuclide transfer in fruits. Information relate to fruit plants grown in agricultural ecosystems of temperate regions. The relative significance of each pathway after release of radionuclides depends upon the radionuclide, the kind of crop, the stage of plant development and the season at time of deposition. Fruit intended as a component of the human diet is borne by plants that are heterogeneous in habits, and morphological and physiological traits. Information on radionuclides in fruit systems has therefore been rationalised by characterising plants in three groups: woody trees, shrubs, and herbaceous plants. Parameter values have been collected from open literature, conference proceedings, institutional reports, books and international databases. Data on root uptake are reported as transfer factor values related to fresh weight, being consumption data for fruits usually given in fresh weight.

    2012-08-01

    Due to the popularity of health effects upon intake of fresh fruits and vegetables, the demand for fresh vegetables and fruit juices has rapidly increased. However, currently, washing is the only procedure for reducing contaminated microorganisms, which obviously limits the shelf-life of fresh vegetable juice (less than 3 days). In this study, we examined the effects of irradiation on the microbiological, chemical and sensory properties of ashitaba and kale juices for industrial application and possible shelf-life extension. Freshly made ashitaba and kale juices already had 2.3×105 and 9.5×104 CFU/mL, respectively. Irradiation of 5 kGy induced higher than 2 decimal reductions in the microbial level, which was consistently maintained during storage for 7 days under refrigerated conditions. Total content of ascorbic acid in vegetable juice decreased upon irradiation in a dose-dependent manner. However, the content of flavonoids did not change, whereas that of polyphenols increased upon irradiation. In sensory evaluation, the ashitaba and kale juices without irradiation (control) scored lower than the irradiated samples after 1 and 3 days, respectively. This study confirms that irradiation is an effective method for sterilizing fresh vegetable juice without compromising sensory property, which cannot be subjected to heat pasteurization due to changes in the bioactivities of the products.

  7. Tropical Fruit Pulps: Processing, Product Standardization and Main Control Parameters for Quality Assurance

    2017-05-01

    Full Text Available ABSTRACT Fruit pulp is the most basic food product obtained from fresh fruit processing. Fruit pulps can be cold stored for long periods of time, but they also can be used to fabricate juices, ice creams, sweets, jellies and yogurts. The exploitation of tropical fruits has leveraged the entire Brazilian fruit pulp sector due mainly to the high acceptance of their organoleptic properties and remarkable nutritional facts. However, several works published in the last decades have pointed out unfavorable conditions regarding the consumption of tropical fruit pulps. This negative scenario has been associated with unsatisfactory physico-chemical and microbiological parameters of fruits pulps as outcomes of little knowledge and improper management within the fruit pulp industry. There are protocols for delineating specific identity and quality standards (IQSs and standardized good manufacturing practices (GMP for fruit pulps, which also embrace standard operating procedures (SOPs and hazard analysis and critical control points (HACCP, although this latter is not considered mandatory by the Brazilian legislation. Unfortunately, the lack of skilled labor, along with failures in complying established protocols have impaired quality of fruit pulps. It has been necessary to collect all information available with the aim to identify the most important hazards within fruit pulp processing lines. Standardizing methods and practices within the Brazilian fruit pulp industry would assurance high quality status to tropical fruit pulps and the commercial growth of this vegetal product towards international markets.

    Full Text Available The nutrient accumulation curves of apple trees are good indicators of plant nutrient demand for each developmental stage. They are also a useful tool to evaluate orchard nutritional status and to estimate the amount of soil nutrient removal. This research aimed at evaluating the seasonality of nutrients in commercial apple orchards during the agricultural years of 1999, 2000, and 2001. Therefore, apple tree leaves and fruits of three cultivars 'Gala', 'Golden Delicious' and 'Fuji' were weekly collected and evaluated for fresh and dry matter, fruit diameter and macronutrient (N, P, K, Ca and Mg and micronutrient (B, Cu, Fe, Mn, and Zn concentrations. Leaf and fruit sampling started one or two weeks after full bloom, depending on the cultivar, and ended at fruit harvest or four weeks later (in the case of leaf sampling. In general, leaf concentrations of N, P, K, Cu, and B decreased; Ca increased; and Mg, Fe, Mn, and Zn did vary significantly along the plant vegetative cycle. In fruits, the initial nutrient concentrations decreased quickly, undergoing slow and continuous decreases and then remaining almost constant until the end of fruit maturation, indicating nutrient dilution, once the total nutrient accumulation increased gradually with fruit growth. Potassium was the nutrient present in highest quantities in apple tree fruits and thus, the most removed from the soil.

  10. [The Advances in the Contamination and Detection of Foodborne Pathogen Noroviruses in Fresh Produce].

    Science.gov (United States)

    Xie, Yajing; Liu, Xianjin

    2015-11-01

    This article reviewed the researches proceeding on the contamination and detection of the foodborne pathogen noroviruses (NoVs) in fresh produce, which involved the NoVs contaminations in fresh produce, the special attachment of NoVs in fresh produce, the NoVs outbreaks associated with fresh produce and the NoVs detection in fresh produce. There had been an increase in reported infectious disease risks associated with the consumptions of fresh produce for recent 30 years. Because the NoVs, as a primary cause of viral gastroenteritis thoughout the world, were highly contagious, had a low infectious dose, and were persistent in the environment. And also the methods for NoVs detection in food had significantly developed over the last 15 years. Currently NoVs were the most common pathogen accounting for 40% of outbreaks associated with fresh produce (i. e., fruits and vegetables). Data from outbreaks investigations verified fresh produce as the high risk food products for NoVs. The fresh produce were typically eaten raw with no thermal processing, can be contaminated at any step during production and processing from faecally polluted water and fertilizers, the poor hygiene practices by food handlers and the cross-contamination. The attachment of NoVs to the fresh produce was due to the physio-chemical factors of virus protein coat, the special attachment to different fresh produce, and the possibility for internalization of NoVs. It might provide answers to why those high risk foods were more frequently implicated (i. e., lettuce and raspberries). According to the data of foodborne NoVs outbreaks which were associated with fresh produce from EU countries and the USA, the outbreaks in EU countries were mainly associated with NoVs contaminated raspberries and lettuce, while in USA which were associated with NoVs contaminated lettuce. Unfortunately, there were no NoVs detection methods for fresh produce or the data of foodborne NoVs outbreaks which were associated with

    Food preservation is critical for keeping fresh-cut products fresh, nutritious, safe, attractive and available for consumers. To improve the safety and quality of fresh-cut fruits, 15 essential oils (EOs) were screened to test the antimicrobial activity against Listeria monocytogenes (LM), Salmonella typhimurium (ST), Staphylococcus aureus (SA) and Escherichia coli O157:H7 (EC O157:H7). The effect of alginate-based edible coating (EC) incorporating different concentrations thyme oil on fresh-cut 'Red Fuji' apples was investigated. Results showed that thyme oil, cinnamon oil and oregano oil were more effective in inhibiting the microbes than other EOs. The result showed that the combined usage of 0.5 µL mL -1 thyme oil incorporated with alginate-based EC could significantly inhibit the microbial growth, respiration, weight loss, firmness and browning of fresh-cut 'Red Fuji' apples. The edible coating and natural additives like thyme oil could be used to preserve the quality of fresh-cut fruits. It revealed that EC incorporated with 0.5 µL mL -1 thyme oil can be a safe preservative for fresh-cut apples. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    We study the cross-correlations of buy and sell volumes on the Korean stock market in high frequency. We observe that the pulling effects of volumes are as small as that of returns. The properties of the correlations of buy and sell volumes differ. They are explained by the degree of synchronization of stock volumes. Further, the pulling effects on the minimal spanning tree are studied. In minimal spanning trees with directed links, the large pulling effects are clustered at the center, not uniformly distributed. The Epps effect of buy and sell volumes are observed. The reversal of the cross-correlations of buy and sell volumes is also detected.

    Full Text Available A description is provided of work performed as part of the fruit logistics infrastructure project commissioned by the South African Deciduous Fruit Producers’ Trust and coordinated by the South African Council for Scientific and Industrial Research, as described in [Van Dyk FE & Maspero E, 2004, An analysis of the South African fruit logistics infrastructure, ORiON, 20(1, pp. 55–72]. After a brief introduction to the problem, two models (a single-commodity graph theoretic model and a multi-commodity mathematical programming model are derived for determining the maximal weekly flow or throughput of fresh fruit through the South African national export infrastructure. These models are solved for two extreme seasonal export scenarios and the solutions show that no export infrastructure expansion is required in the near future - observed bottlenecks are not fundamental to the infrastructure and its capacities, but are rather due to sub-optimal management and utilisation of the existing infrastructure.

    Full Text Available Vegetable freshness is very important for both restaurant and home consumers. In market, sellers frequently apply water to leafy vegetables to make them not lose weight and look fresh; however, these vegetables may not be stored for a long time as they appear. After a time limit, they may be quickly rotten. It is thus meaningful to investigate early and simple detection tools to measure leafy vegetable freshness while they are frequently applied water in selling. In this work, three types of newly harvested leafy vegetables were bought from a local farmer market and stored in the air with room temperature and roots submerging in water. Chlorophyll a fluorescence (ChlF from the vegetables was measured each half a day for three days. The obtained ChlF data were analyzed statistically and the correlation of ChlF parameters and vegetable freshness/storage time was obtained. The k-mean classification was also performed. It is found that Fo, Fj, Fm/Fo, and Fv/Fm can be used as an early detection tool to differentiate the freshness of leafy vegetables on which water is constantly applied in storage without visible difference.

    The liberalization of the natural gas market in Europe has all kinds of juridical aspects. Not only with respect to new legislation (Natural Gas Law and Mining Law), but also changes in juridical structures of natural gas companies, caused by privatization or splitting up in a mains management company and a distribution company. In a series of articles lawyers of the Energy Working Group of Houthoff Buruma in The Hague, Netherlands, discuss the developments at the natural gas market. In this third part, attention will be paid to how authorities involved (municipalities, provinces) can prepare themselves properly with respect to selling the gas company and how they can retain their influence on the future activities of the gas company using legal and contractual agreements. In the article also attention is paid to the various stages of a sale

    Nuclear Electric, the state-owned company that operates nuclear power stations in England and Wales, has applied to compete directly with privatized electricity generating companies in the sale of electricity to major customers. Since its formation in 1990, NE has had to sell all of its electrical output through the so-called pool operated by the National Grid Company, and then to 12 regional distribution companies that have franchises for about 75 percent of electricity consumption in their regions. On the other hand, the two large companies that took over the fossil-fuel power stations at the time of privatization, and other new independent companies that are building combined-cycle gas-turbine plants, are allowed to conclude supply contracts directly with large industrial customers

    Based on our experience in representing more than 100 doctors and medical specialists in practice sales and acquisitions, we have identified 11 key considerations important to a deal. There are several issues to consider while going through the process of buying or selling a practice including the implementation of a "letter of intent" as a first step rather than drafting a contract, securing a lease, and verifying the property is not in violation of the local zoning requirements. There are also considerations with regard to the patients, which range from how will the accounts receivable at the time of the closing be handled to who is responsible for the handling of continued treatment in an ongoing case after a deal is finalized. This article details these considerations and more.

    2005-06-01

    To determine if flower nutrient composition can be used to predict fruit quality, a field experiment was conducted over three seasons (1996-1999) in a commercial orange orchard (Citrus sinensis (L.) Osbeck cv. 'Valencia Late', budded on Troyer citrange rootstock) established on a calcareous soil in southern Portugal. Flowers were collected from 20 trees during full bloom in April and their nutrient composition determined, and fruits were harvested the following March and their quality evaluated. Patterns of covariation in flower nutrient concentrations and in fruit quality variables were evaluated by principal component analysis. Regression models relating fruit quality variables to flower nutrient composition were developed by stepwise selection procedures. The predictive power of the regression models was evaluated with an independent data set. Nutrient composition of flowers at full bloom could be used to predict the fruit quality variables fresh fruit mass and maturation index in the following year. Magnesium, Ca and Zn concentrations measured in flowers were related to fruit fresh mass estimations and N, P, Mg and Fe concentrations were related to fruit maturation index. We also established reference values for the nutrient composition of flowers based on measurements made in trees that produced large (> 76 mm in diameter) fruit.

    Little research exists about the factors influencing the foods available at family meals. This study examines the home food environment factors contributing to the presence of fruit and vegetables at family meals. Home food inventory (HFI) and survey data were collected from low-income, minority families (n = 120) with children 6-12 years old. Observations from video-recorded family dinner meals, totaling 800 videos, were used to measure the frequency at which fruit and vegetables were served. Multiple regression was used to investigate how the fruit and vegetables in the HFI and other home food environment factors were related to the number of days fruit and vegetables were served at dinner during the observation period. Availability and accessibility of fruit and vegetables in the home were each found to be significantly associated with the presence of fruits and vegetables at family dinners. Of the fruit and vegetable categories (i.e., fresh, canned, or frozen), having fresh fruit and vegetables available in the home was found to be most strongly associated with serving fruit and vegetables at dinner, respectively. Higher parent intake of vegetables was associated with the presence of vegetables at dinners, and parent meal planning was associated with the presence of fruit at dinners. Increasing the availability and accessibility of fresh fruit and vegetables in the home may be an effective approach to increasing the presence of fruits and vegetables at family dinners, especially among low-income, minority households. It is also essential to understand why families are not using all fruits and vegetables (e.g., canned and frozen) available in the home for family meals. Family meals are a place to promote the increased presence of both fruit and vegetables. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available In today’s marketing era, consumers seem to have known about marketed products and no longer need explanation from a salesperson. The interaction between company and target consumers can be marketed through new media such as email, Facebook, WA, Instagram, and other forms. Such situations need to be in-depth researched in terms of whether personal selling contribution is still needed in marketing communication activities. Considering the uniqueness and personal selling advantages turns out that personal selling is an important partner that can not be replaced by other forms of marketing communications even if there is exposure to new media to promote products. The specialty of personal selling lies in its ability to interact directly to improvise the sales process through person to person communication. Dalam era pemasaran masa kini nampaknya konsumen dianggap sudah mengetahui tentang produk yang dipasarkan dan tidak memerlukan lagi penjelasan dari seorang wiraniaga. Interaksi perusahaan dengan pembeli sasaran dapat dilakukan melalui media baru seperti email, facebook, WA, instagram dan bentuk lainnya. Situasi demikianlah yang memerlukan kajian mendalam dalam kaitannya bagaimana peran personal selling dalam kegiatan komunikasi pemasaran di era digital? Memperhatikan keunikan dan kelebihan personal selling ternyata personal selling merupakan mitra penting yang tidak dapat tergantikan oleh bentuk komunikasi pemasaran lainnya sekalipun ada terpaan media baru untuk mempromosikan produk.

    2016-05-01

    Reduction of the availability of tobacco has been proposed as a means of reducing and denormalising tobacco use. Some retailers have stopped selling tobacco. Therefore, we investigated how willing New Zealand convenience store owners were to stop selling tobacco or sell nicotine replacement therapy. Promotion of their stores was offered as an incentive to stop selling tobacco. We asked convenience store owners in the Auckland metropolitan region of New Zealand to choose one of three actions. The first was to stop selling tobacco for a short period of time; the second was to restrict the hours that they sold tobacco; the third was to display and sell nicotine replacement therapy. All participating retailers completed a short interview about selling tobacco. We also surveyed customers about nicotine replacement and cessation. One-third of eligible retailers agreed to participate. Most who participated (93%) were unwilling to stop or restrict tobacco sales and 2 (7%) had already stopped selling tobacco. Tobacco was perceived as a key product for their businesses. Very few customers who purchased cigarettes noticed nicotine replacement therapy or obtained it from convenience stores. Substantially reducing the availability of tobacco in communities is likely to require legislative approaches, underpinned by sustained community pressure and support for convenience store owners who are willing to change their business model.

    Fresh fruits and vegetables are an important part of a healthful diet. They provide vitamins, minerals and fiber to help keep our body healthy. Occasionally, fresh fruits and vegetables can become contaminated with harmful bacteria or viruses, which are also known as pathogens. The major family of pathogen associated with food are members of Enterobacteriaceae which commonly form a part of microbiological criteria and their presence is traditionally related to hygiene and safety of foods. Organic fertilizers, irrigation water quality and soil are major source of contamination. For removal of pathogens, various decontamination procedures are also followed to reduce microbial load on the fruits. These are chemical preservatives and irradiation. Microbiological study of fresh produce can be done by various phenotypic, biochemical and molecular techniques so that pathogen can properly be identified. The World Health Organization (WHO) developed global risk communication message and training materials to assist countries in strengthening their food educating programs. There is a need for improved surveillance systems on food-borne pathogens, on food products and on outbreaks so that comparable data are available from a wider range of countries.

  19. A fruit quality gene map of Prunus

    Directory of Open Access Journals (Sweden)

    Bliss Fredrick A

    2009-12-01

    Full Text Available Abstract Background Prunus fruit development, growth, ripening, and senescence includes major biochemical and sensory changes in texture, color, and flavor. The genetic dissection of these complex processes has important applications in crop improvement, to facilitate maximizing and maintaining stone fruit quality from production and processing through to marketing and consumption. Here we present an integrated fruit quality gene map of Prunus containing 133 genes putatively involved in the determination of fruit texture, pigmentation, flavor, and chilling injury resistance. Results A genetic linkage map of 211 markers was constructed for an intraspecific peach (Prunus persica progeny population, Pop-DG, derived from a canning peach cultivar 'Dr. Davis' and a fresh market cultivar 'Georgia Belle'. The Pop-DG map covered 818 cM of the peach genome and included three morphological markers, 11 ripening candidate genes, 13 cold-responsive genes, 21 novel EST-SSRs from the ChillPeach database, 58 previously reported SSRs, 40 RAFs, 23 SRAPs, 14 IMAs, and 28 accessory markers from candidate gene amplification. The Pop-DG map was co-linear with the Prunus reference T × E map, with 39 SSR markers in common to align the maps. A further 158 markers were bin-mapped to the reference map: 59 ripening candidate genes, 50 cold-responsive genes, and 50 novel EST-SSRs from ChillPeach, with deduced locations in Pop-DG via comparative mapping. Several candidate genes and EST-SSRs co-located with previously reported major trait loci and quantitative trait loci for chilling injury symptoms in Pop-DG. Conclusion The candidate gene approach combined with bin-mapping and availability of a community-recognized reference genetic map provides an efficient means of locating genes of interest in a target genome. We highlight the co-localization of fruit quality candidate genes with previously reported fruit quality QTLs. The fruit quality gene map developed here is a

  20. Technology Optimization of Lysozyme's Fresh Maintaining Effect on Apple.

    Science.gov (United States)

    Jun-Hong, Liu; Kun-Yu, Wang

    2016-10-03

    Lysozyme is a kind of alkaline globin, which functions well in the degradation of the cell wall of microbe. Currently, lysozyme is widely used in various fields, such as medicine, fruit, and vegetable industry, dairy industry, and so on. Therefore, the exploitation and utilization of lysozyme is of significant economic benefit. Taking apple as material, weight loss ratio and reducing sugar content as objectives, this paper studied the fresh-keeping effect of lysozyme. Influential factors, lysozyme concentration, soaking time, modified temperature, and reaction time were discussed in detail. The results showed that reducing sugar content was 2.043% and the weight loss ratio was the minimum in the presence of soaking time of 2 min, modified temperature of 65 °C, reaction time of 4 d, and lysozyme concentration of 0.5 g/L. © 2016 Institute of Food Technologists®.

  1. Factors Associated With American Indian and White Adolescent Drug Selling in Rural Communities

    Eitle, David; Eitle, Tamela McNulty

    2014-01-01

    Relatively few studies have examined the correlates of adolescent drug selling in America, with most of these studies focusing on urban settings. The present study examines the risk and protective factors associated with drug selling among American Indian and white adolescents residing in a rural Northwestern state in the United States. Using survey data collected in 2010-2012, we conduct logistic regression analyses exploring the correlates of drug selling (n=568). Generally, we found support for prior explanations of drug selling, but identified some important race-specific differences. Specifically, we found that stress exposure was a risk factor for American Indians, but not whites. Conversely, academic achievement served as a protective factor for white adolescents but not American Indians. Our findings suggest that the race gap in rural drug selling can be explained by considering differences in social bonds, stress exposure, and exposure to substance using family and friends.

    Traditionally, the commercial activities of gas companies have been limited almost exclusively to the sale of gas. However, several socioeconomic factors specific to the gas industry, such as increasing customer expectations, competition between gas operators, a growing emphasis on services in many companies and the opening of public monopolies to competition, will bring inevitable change. Moreover, these developments coincide with imminent gas market opening. In response to the changing situation, the gas industry will seek to develop a range of multi-service offers, probably through external partnerships. (authors)

    This article explores how virtual worlds are rhetorically constructed as obvious, innovative spaces for communication about architecture. It is argued that the marketization of an innovative use of new media platforms happens in early phases of the innovation processes, and the success of new media...... of the communication about the innovation. It is demonstrated that the creation of markets does not begin when innovations such as Virtual Worlds Architecture are settled, but is intertwined with early expectations about their promises and limitations. Rather than seeing virtual worlds as settled and secluded sites...

    Background: Higher intakes of fruits and vegetables, rich in micronutrients, have been associated with better mental health. However, cooking or processing may reduce the availability of these important micronutrients. This study investigated the differential associations between intake of raw fruits and vegetables, compared to processed (cooked or canned) fruits and vegetables, and mental health in young adults. Methods: In a cross-sectional survey design, 422 young adults ages 18–25 (66.1% female) living in New Zealand and the United States completed an online survey that assessed typical consumption of raw vs. cooked/canned/processed fruits and vegetables, negative and positive mental health (depressive symptoms, anxiety, negative mood, positive mood, life satisfaction, and flourishing), and covariates (including socio-economic status, body mass index, sleep, physical activity, smoking, and alcohol use). Results: Controlling for covariates, raw fruit and vegetable intake (FVI) predicted reduced depressive symptoms and higher positive mood, life satisfaction, and flourishing; processed FVI only predicted higher positive mood. The top 10 raw foods related to better mental health were carrots, bananas, apples, dark leafy greens like spinach, grapefruit, lettuce, citrus fruits, fresh berries, cucumber, and kiwifruit. Conclusions: Raw FVI, but not processed FVI, significantly predicted higher mental health outcomes when controlling for the covariates. Applications include recommending the consumption of raw fruits and vegetables to maximize mental health benefits. PMID:29692750

    Full Text Available The problem of locating distribution centers for delivering fresh food as a part of electronic commerce is a strategic decision problem for enterprises. This paper establishes a model for locating distribution centers that considers the uncertainty of customer demands for fresh goods in terms of time-sensitiveness and freshness. Based on the methodology of robust optimization in dealing with uncertain problems, this paper optimizes the location model in discrete demand probabilistic scenarios. In this paper, an improved fruit fly optimization algorithm is proposed to solve the distribution center location problem. An example is given to show that the proposed model and algorithm are robust and can effectively handle the complications caused by uncertain demand. The model proposed in this paper proves valuable both theoretically and practically in the selection of locations of distribution centers.

    Full Text Available Faecal contamination of fresh fruits represents a severe danger for human health. Thus some techniques based on microbiological testing were developed to individuate faecal contaminants but those tests do not results efficient because their non-applicability on overall vegetable unity. In this work a methodology based on hyper-spectral fluorescence imaging was developed and tested to detecting faecal contamination on fresh tomatoes. Two image-processing methods were performed to maximise the contrast between the faecal contaminant and tomatoes skin: principal component analysis and band image ratio (BRI. The BRI method allows classifying correctly 70% of contaminated area, with no false-positives in all examined cases. Thus, the developed methodology can be employed for a fast and effective detection of faecal contamination on fresh tomatoes.

    Full Text Available Since ancient times, the preservation of fruit and vegetables is an ancient method of drying. Sun drying method has been used more widely. In general, consumer-ready products are dried fruits, while the dried vegetables are the foods subjected to the rehydration processes such as boiling, heating and baking before consumption. In recent years, new products with high eating quality have been attempted to achieve without losing characteristic of raw material. With the improving of food technology, using developed methods (pH reduction with reducing aw, slight heating, preservatives use etc. as protective agent, and using a combination of a low rate as an alternative to traditional food preservation process, products have been obtained without changing original characteristics of food. ‘Semi-dried 'or 'medium moist 'products with little difference between the taste and texture of the product with a damp have gained importance in recent years in terms of consumer preferences. Vegetables or fruits, which have water activity levels between 0.50 and 0.95 and the moisture content of between 26% and 60%, are called 'medium moist fruit or vegetables'. Two different manufacturing process to obtain a semi-dried or intermediate moisture products are applied. First, fully dried fruits and vegetables to be rehydrated with water are brought to the desired level of their moisture content. Second, in the first drying process, when the product moisture content is reduced to the desired level, the drying process is finished. The semi-dried products are preferred by consumers because they have a softer texture in terms of eating quality and like fresh products texture.

  9. Family planning and the labor sector: soft-sell approach.

    Dr. Cesar T. San Pedro, the director of the company clinic at Dole Philippines plantation in South Cotabato in Region 11, has been pressing the management to initiate a comprehensive family planning programs for their 10,000 workers. Pedro wants the Ministry of Labor and Employment (MOLE) to enforce its population program. The situation at Dole is one that requires an arbiter. Since 1977, there has not been a Population/Family Planning Officer (PFPO) for the area, and it is not possible to monitor closely if the qualified firms are following the labor code and providing family planning services to their employees. Susan B. Dedel, executive director of the PFPO, has reported that the office has sought to endear its program to the private sector by showing that family planning is also profitable for the firm. This "soft-sell" approach has been the hallmark of the MOLE-PFPO since it began in 1975 as a joint project of the Commission on Population (POPCOM), United Nations Fund for Population Activities (UNFPA), and International Labor Organization (ILO). Some critics have argued that this liberal style of implementation is short-selling the program. They point out that the Labor Code of 1973 enforces all establishments with at least 200 employees to have a free in-plant family planning program which includes clinic care, paid motivators, and volunteer population workers. The critics seem, at 1st glance, to have the statistics on their side. In its 5 years of operation, the PFPO has convinced only 137,000 workers to accept family planning. This is quite low, since of the 1.2 million employed by the covered firms, 800,000 are eligible for the MOLE program. Much of the weakness of the implementation is said to be due to the slow activation of the Labor-Management Coordinating Committees (LMCC). The critics maintain that because of the liberal enforcement of Department Order No. 9, the recalcitrant firms see no reason to comply. Dedel claims that the program is on the

    Due to the popularity of health effects upon intake of fresh fruits and vegetables, the demand for fresh vegetables and fruit juices has rapidly increased. However, currently, washing is the only procedure for reducing contaminated microorganisms, which obviously limits the shelf-life of fresh vegetable juice (less than 3 days). In this study, we examined the effects of irradiation on the microbiological, chemical and sensory properties of ashitaba and kale juices for industrial application and possible shelf-life extension. Freshly made ashitaba and kale juices already had 2.3×10 5 and 9.5×10 4 CFU/mL, respectively. Irradiation of 5 kGy induced higher than 2 decimal reductions in the microbial level, which was consistently maintained during storage for 7 days under refrigerated conditions. Total content of ascorbic acid in vegetable juice decreased upon irradiation in a dose-dependent manner. However, the content of flavonoids did not change, whereas that of polyphenols increased upon irradiation. In sensory evaluation, the ashitaba and kale juices without irradiation (control) scored lower than the irradiated samples after 1 and 3 days, respectively. This study confirms that irradiation is an effective method for sterilizing fresh vegetable juice without compromising sensory property, which cannot be subjected to heat pasteurization due to changes in the bioactivities of the products. - Highlights: ► We examined the effects of irradiation of fresh vegetable juices (ashitaba and kale) for industrial application. ► Irradiation of 5 kGy induced higher than 2 decimal reductions in the microbial level. ► Ascorbic acid in vegetable juice decreased upon irradiation in a dose-dependent manner. ► Content of flavonoids did not change whereas that of polyphenols increased. ► There was no change in sensory properties after irradiation.

    The effects of freeze-drying on antioxidant compounds and antioxidant activity of five tropical fruits, namely starfruit (Averrhoa carambola L.), mango (Mangifera indica L.), papaya (Carica papaya L.), muskmelon (Cucumis melo L.), and watermelon Citruluss lanatus (Thunb.) were investigated. Significant (p dried fruit samples, except muskmelon. There was no significant (p > 0.05) change, however, observed in the ascorbic acid content of the fresh and freeze-dried fruits. Similarly, freeze-drying did not exert any considerable effect on β-carotene concentration of fruits, except for mango and watermelon, where significantly (p dried fruits. Overall, in comparison to β-carotene and ascorbic acid, a good correlation was established between the result of TPC and antioxidant assays, indicating that phenolics might have been the dominant compounds contributing towards the antioxidant activity of the fruits tested.

    Effect of gamma irradiation (0.25 to 1.0kGy) on antioxidant properties of ber fruit was studied. Antioxidant properties of ber fruits were determined by scavenging DPPH radical activity, reducing power assay, super oxide anion radical activity, TBARS, total phenolic content and total flavonoid content. Gamma irradiation treatment up to 1.0 kGy elevated the scavenging DPPH radical activity (9 %), super oxide anion radical activity (26 %) and total flavonoid content (208 %) compared to fresh ber fruit. On the other hand it brought down the reducing power activity (65 %) and total phenolic content (18 %) as compared to raw fruit. The TBARS activity statistically increased upon irradiation of ber fruit. It indicated that total antioxidant activity decreased as TBARS value increased. Therefore 0.25 to 0.5kGy is better dose to retain the natural antioxidant in fruit. (author)

    Hawaii is a pioneer in the use of phytosanitary irradiation. Irradiation is an approved treatment to control quarantine insect pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping tropical fruits and vegetables to the US mainland using irradiation since 2000. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5,500 tonnes). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) has accelerated commodity export approvals and facilitated adoption by foreign trading partners. Current impediments to wider adoption include the labeling requirement, the 1 kGy limit for fresh horticultural products, and non-acceptance of phytosanitary irradiation in Japan and the European Union. USDA Animal and Plant Health Inspection Service (APHIS) has restricted the use of modified atmosphere packaging (MAP) for irradiated fresh fruits exported to the US due to possible increased radio-tolerance in the target insects. Data are presented for response of melon fly in papaya to several types of MAP with radiation treatment at 45-65 Gy. Low oxygen atmospheres can increase insect radio-tolerance, but the effect is dependent on oxygen concentration and radiation dose. (author)

    Twenty four male albino rats, body weight 100-130 g, were used to evaluate the protective role of fresh pomegranate fruit intake for 30 days on the damage induced by single dose of 6 Gy whole body gamma irradiation. The rats were randomly and equally divided into four groups: group (1): control, group (2): irradiated with 6 Gy, group (3): pomegranate for 30 days and group (4): pomegranate for 30 days followed by 6 Gy whole body irradiation. At the end of the experiment, all rats were sacrificed after 12 hours fasting then sera were separated for the determination of sugar, total antioxidant, lipid profile and liver and kidney functions. Results showed that gamma radiation caused significant decline (P<0.05) in serum total antioxidant, total protein, albumin, HDL-C and blood glucose with significant elevation (P<0.05) in other hepato-renal markers in addition to serum total cholesterol, triglycerides and LDL-C. These changes were significantly attenuated in irradiated animals pre-treated with whole fresh pomegranate fruit leading to the conclusion that pre-intake of pomegranate fruit had a radio- protective effect. This protection of this whole fruit may be due to the increased total antioxidant level leading to free radical scavenging

    Persimmon is a seasonal fruit and only available in fresh form for a short period of each year. In addition to freezing, drying is the simplest substitute for the fresh fruit and accessible throughout the year. The effect of mellowing and drying was evaluated in 'Tipo' persimmon, an astringent cultivar. 'Tipo' firm fruit contained high levels of tannins (1.1 mg g(-1) DW), which were naturally decreased to 0.2 mg g(-1) DW after mellowing. The drying process greatly impacted the contents of carotenoids, total phenols, individual phenolics, tannins, organic acids, sugars and colour parameters in firm and mellow fruit. The reduction of tannins, phenolic compounds and organic acids were accompanied by the increase of sugars and carotenoids, improving the colour of the analysed samples. These results showed that the drying process improved the quality of persimmon products and extended their shelf life. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    As the Indian population is increasing, the demand for fresh fruits and vegetables is also increasing. Owing to the perishable nature and very short shelf life, these items require proper storage and transportation facilities in order to reach to the customer in fresh state. A lack of investment in agriculture makes the country vulnerable to international price shocks as well as exchange-rate volatility. This requires a considerable amount of effort from the involved parties. The entire chain...

    Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues of agrochemicals. Organic farming practices such as the use of animal manure can however increase the risk of contamination by enteric pathogenic microorganisms and may consequently pose health risks. A number of scientific studies conducted in different countries have compared the microbiological quality of produce samples from organic and conventional production and results are contradictory. While some have reported greater microbial counts in fresh produce from organic production, other studies do not. This manuscript provides a brief review of the current knowledge and summarizes data on the occurrence of pathogenic microorganisms in vegetables from organic production.

    Although fresh fish is widely available, consumption still remains below the recommended intake levels among the majority of European consumers. The economic crisis affects consumer food behaviour, therefore fresh fish is perceived as healthy but expensive food product. The aim of this study was to determine the factors influencing fresh fish consumption using an expanded Theory of Planned Behaviour (Ajzen, 1991) as a theoretical framework. The survey was conducted on a heterogeneous sample of 1151 Croatian fresh fish consumers. The study investigated the relationship between attitudes, perceived behavioural control, subjective norm, moral obligation, involvement in health, availability, intention and consumption of fresh fish. Structural Equation Modeling by Partial Least Squares was used to analyse the collected data. The results indicated that attitudes are the strongest positive predictor of the intention to consume fresh fish. Other significant predictors of the intention to consume fresh fish were perceived behavioural control, subjective norm, health involvement and moral obligation. The intention to consume fresh fish showed a strong positive correlation with behaviour. This survey provides valuable information for food marketing professionals and for the food industry in general. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Rumstay, Kenneth S.

    2018-01-01

    For well over a century the iconic image of the astronomical telescope has been widely used to promote distinctly non-astronomical consumer goods. One of the most famous of early examples is the 1893 Chicago newspaper advertisement for Kirk’s Soap, which was inspired by the opening of the Yerkes Observatory. But such usage was not limited to periodicals. Advertising trade cards had become popular at the end of the 17th century in Europe, notably in Paris and London. In a time prior to the introduction of formal systems of street address numbering, they served as both advertisement and map, directing consumers to the merchants' stores. In many cases, attention was drawn to the product by picturing it as a heavenly body to be observed telescopically! In the 20th century trade cards gave way to the modern business card, and manufacturers began to increasingly rely on magazine and newspaper (and radio and television) advertising. But the telescope remains an evocative image! In modern advertising we see it used to sell an incredible variety of consumer goods: candy, coffee, cigarettes, whiskey, foodstuffs, clothing; the list is endless! Examples of these, along with earlier Victorian-era usages, are presented. This work was supported by a faculty development grant from Valdosta State University.

  8. ON PRICE CHOICE AT SELLING OF INFORMATION RESOURCES

    Directory of Open Access Journals (Sweden)

    O. S. Ivanova

    2015-05-01

    Full Text Available The paper considers the problem of the pricing policy determination in the company, selling information resource at the market. The problem of the optimal price determination for an information resource is solved depending on the time for the case when the seller-company has no competitors in the market, the market is saturated, and buyers are not able to further spread of the resource. Conditions for the optimal choice of information resource price have been obtained; the maximum possible income of the company has been calculated for linear demand function, and conditions, determining the duration and volume of sales, providing the maximum of average income of the company, have been obtained as well. The problem of optimal price choice is solved by macrosystem approach that has made it possible to reduce it to the isoperimetric kind. It is shown that the optimal price dependence on time for a linear demand function should provide a linearly increasing rate of sales. Conditions have been derived under which the sales proceedings for an information resource are positive, relationship is determined between volume of sales and timeline at which the average income during the sales reaches its maximum. The results are given in dimensionless form, thereby reducing the number of independent parameters. These results are usable for the pricing analysis of software and other information products.

    2010-09-01

    Full Text Available In the present society, also identified as a "consumer society" (Bauman, 2008, people, irrespective of gender, age, social and financial conditions, are all called for consumption. In this article we turn to the childhood and approached one of the faces of their insertion into the society of consumers, trying to show how children are used to sell. As a frame of theoretical reference we adopt, among others, the writings of Zygmunt Bauman, Juliet Schor and Robert Bocock, dealing with contemporary versions of consumption. Analyzing weekly magazines of large circulation, we discuss how productive it is for the economic market the alliance between childhood and consumption and we argue that this use of children in publicity contributes for a new conception of childhood: the childhood of consumption. An erotized childhood, always wanting more and never feeling satisfied, focused in acquiring and showing off. This is the childhood that is coming to school with new interests, preferences and behavior, deserving our entire attention. Key-words: contemporary childhood, childhood and consumption, consumer society, advertising, magazines.

Herewith, so far, the approach of the competent authorities of some countries including Ukraine can be called prevailing in quantitative terms under which the official prohibition on distance sales of medicines is set. The aim of this study is a detailed examination of the nature of the prohibition of the medicines distance selling in Ukraine, namely the an analysis of advantages and disadvantages of this form of distribution of medicines and identification of appropriate ways for gradual repeal of the prohibition in terms of regulatory reform in Ukraine in the sphere of circulation of medicines due to the process of adaptation of statutory regulation in this area to the EU legislation. This study is based on Ukrainian regulation acts, Council Directives 97/7/EC, 2000/31/EC, 2001/83/EC, scientific works and opinions of progressiveminded people in this sphere. Such methods as dialectical, comparative, analytic, synthetic and comprehensive have been used in the article. Reception of the described experience of regulation in EU will allow a further review of the principles of regulation in Ukraine in the sphere of medicines with a shift in the main emphasis in the direction of ensuring adequate consumer rights in this area and preventing the risks of patients' and public health.

  11. Selling orthodontic need: innocent business decision or guilty pleasure?

    The principal objective for most patients seeking orthodontic services is a detectable improvement in their dentofacial appearance. Orthodontic treatment, in the mind of the patient, is something that makes you look better, feel better about yourself, and perhaps enhances your social possibilities, ie, to find a companion or make a positive impression during a job interview. Orthodontics, as a speciality, has collectively advanced the idea that enhanced occlusion (bite) improves the health and longevity of the dentition, and as a result many patients seeking orthodontic services affirm that their secondary goal of treatment is an oral health benefit. It would appear that there is some disparity between the end-user of orthodontic services and the orthodontic provider's perception of what constitutes orthodontic need. The aim of this paper is to examine two contrasting models that characterise how dentists 'sell' orthodontic services to patients and to discuss the conflict between professional ethics, practice management and evidence-based decision-making in orthodontic practice.

    Full Text Available The purpose of the research is to investigate Romanian direct sellers’ perceptions on customers’ loyalty. The research objectives are: (1 to identify the direct sellers’ perceptions on the concept of loyalty; (2 to identify the main loyalty techniques that direct sellers use in their work with the clients; (3 to frame the portrait of a loyal customer. As a research method, we used qualitative research based on depth interviews. It is an exploratory and instrumental research, the results being used for building a questionnaire for a future survey. The investigated population is represented by direct selling women, with ages beteeen 19 and 30 years. For direct sellers, loyalty is an attitude and also a behavior, it means buying from the same company, from the same seller and preferring the products of the company. The main loyalty techniques that direct sellers use in their work with the clients are: promotional actions, personalization the relation with the client and offering stimulants. The loyal customer is the one who buys companies’ products every month or at least quarterly, spends a monthly amount of 100 Ron on these products, works with the same seller, pays on time for the order, doesn’t look only after promotions, loves the products, recommends the company to others, doesn’t return the order, wants to buy more products from the company and trusts its products.

  13. The selling of mental health services: some ethical reflections.

    1993-01-01

    Since the introduction of public mental health services in Israel, the main principle of our work has been to provide equal and free of charge health services to all patients. We were proud of our ability to provide optimal treatment to all patients in all our facilities, regardless of cost or status of insurance. During the last decade, the cost of providing good quality public health services, including mental health services, has constantly increased, and the system has reached a state of financial distress resulting in insufficiency and inability to perform properly. In order to maintain the level of mental health services, the health authorities started planning a system of payment for various mental health services which, until now, were supplied free of charge. This change of policy and attitude towards the population in need poses severe ethical and practical questions and problems. It is questionable that the amount of income ensuing from the sale of mental health services and whether a relatively small financial profit justify possible injury of the population in need of these services, especially the sicker and weaker members of it. This article raises some ethical doubts involved in charging money for psychiatric services that are given to this special group of the mentally ill, and claims that the feasibility of selling services in this area of public health should be reinvestigated.

    Full Text Available Fruit juices are popular drinks as they contain antioxidants, vitamins, and minerals that are essential for human being and play important role in the prevention of heart diseases, cancer, and diabetes. They contain essential nutrients which support the growth of acid tolerant bacteria, yeasts, and moulds. In the present study, we have conducted a microbiological examination of freshly prepared juices (sweet lime, orange, and carrot by serial dilution agar plate technique. A total of 30 juice samples were examined for their microbiological quality. Twenty-five microbial species including 9 bacterial isolates, 5 yeast isolates, and 11 mould isolates were isolated from juices. Yeasts and moulds were the main cause of spoilage of juices. Aspergillus flavus and Rhodotorula mucilaginosa were observed in the maximum number of juice samples. Among bacteria Bacillus cereus and Serratia were dominant. Escherichia coli and Staphylococcus aureus were detected in few samples. Candida sp., Curvularia, Colletotrichum, and Acetobacter were observed only in citrus juice samples. Alternaria, Aspergillus terreus, A. niger, Cladosporium, and Fusarium were also observed in tested juice samples. Some of the microorganisms detected in these juice samples can cause disease in human beings, so there is need for some guidelines that can improve the quality of fruit juices.

    Full Text Available BACKGROUND: For the first time, a morphometric characterization of chaura (Gaultheria pumila fruits has been conducted between natural populations growing in the Villarrica National Park, Araucania Region, Chile. Chaura is a native Ericaceae from Chile that produces aromatic and tasty fruits which could be of agricultural interest. RESULTS: To influence the decision for a further domestication of G. pumila, both the fruit sizes (indicator of productivity and the nutritional properties of the fruits have been determined from different subpopulations. Samples were a total of 74 plants and 15 fruits per plant which were randomly harvested following its natural distribution around the Villarrica volcano. Altogether, fresh weight, shape, color, diameter in the pole and the equatorial dimensions were determined as phenotypic traits of the G. pumila fruits. Meanwhile the total soluble solids, anthocyanin and pectin contents were calculated as nutritional traits of the Chaura fruits. Results showed a high phenotypic diversity between the sampled population with three main fruit shapes and three predominant colors. The round shapes were the most abundant, whereas a significant correlation was found among fruit size with weight and color. The highest fresh weight (597.3 mg, pole diameter (7.1 mm and equatorial diameter (6.5 mm were estimated in the pink color fruits. CONCLUSIONS: The total amount of anthocyanin was higher in red fruits, while the maximum pectin content was obtained in the round white fruits. Overall results must pave the way for a further domestication and introduction of the Chaura species in the agro-productive system in Chile.

    A selection of Australian and imported fresh and dried fruit products, including sultanas, Sunmuscats, Carina currants, Zante currants, apricots, and prunes, were analyzed for selected minerals (Ca, Mg, Na, S, B, Al, Fe, Mn, Cu, Zn, Mo, and Se), folate and vitamin C, and the capacity of dried fruits for dietary provision of these micronutrients evaluated. Micro-nutrients were concentrated by a factor of 3-5 in dried fruits compared with their fresh fruit counterparts and were consequently present in nutritionally significant levels, in contrast to fresh fruit. Australian dried sultanas, Carina currant, Zante currant, apricots, and prunes contained Cu, Fe, K, and Mn at levels of >20% of daily Required Dietary Intake (RDI, taken as the average for adult men and women as nominated by the Australian National Health and Medical Research Council) and Sunmuscats contained Cu, Fe, and K at >20% of RDI. All dried fruits studied contained boron in the range of 1.5 to 5.4 mg per 100 g; however, the RDI for boron has not been defined by the NHMRC at the present time. All sultanas and currants studied contained folate at levels of 10-20% of RDI per 100 g. Experimental drying methods significantly affected folate levels with higher folate content in non-ground versus ground-based drying methods. Of the micro-nutrients supplying >20% of RDI, folate represents a particular nutrient for which the mean daily intake of adult Australians is typically inadequate. This study shows that dried fruit consumption, in contrast with fresh fruit, can provide significant proportions of daily requirements of several micronutrients, particularly folate.

    2011-09-01

    There has been limited research on how recessions (or more generally, the strength of the economy) affect drug use and the related outcome of drug selling. This is especially important, given the current economic crisis. This paper aims to use a conceptual framework, previous research, and new research to predict how the current economic crisis may be affecting youth drug selling and drug use. A conceptual framework to understand how a recession could affect youth drug selling and drug use is presented, along with a review of the literature on empirical investigations on how the strength of the economy affects these behaviours among teenagers. In addition, new analyses for young adults are presented. The conceptual framework postulates that a recession would have direct positive effects on the prevalence of youth drug selling but ambiguous direct effects on youth drug use. The conceptual framework also postulates that drug selling and drug use are inter-connected at the individual level and the aggregate level. Thus, any effect of a recession on one would likely affect the other in the same direction. The limited empirical evidence indicates that both drug selling and drug use among youth are higher when the economy is weaker. The current economic crisis will likely increase both youth drug selling and drug use relative to what they would have otherwise been. Published by Elsevier B.V.

    Although studies have found that young adults who sell drugs are more likely to be involved in risky behaviors than those who do not sell drugs, there has been relatively little research that has explored heterogeneity among young adults who sell drugs. Using a pooled sample of 18 to 25 year olds from the National Survey on Drug Use and Health (2006-2010) who report past-year drug selling (N = 5,373), this study employs latent profile analysis to specify latent groups and assess the correlates of group membership. Findings indicate substantial differences among young adults who sell drugs. In particular, the analysis found four groups of drug sellers: normative (49.6%), club drug users (23.6%), polysubstance users (16.0%), and criminal offenders (10.8%). Club drug users were characterized by high levels of ecstasy and hallucinogen use, polysubstance users were more likely to be depressed and anxious, White and female than the other groups. Criminal offenders were overwhelmingly male and more likely to be comprised of African-Americans and Hispanics. RESULTS indicate that drug selling in early adulthood varies substantially. Contrary to media and popular notions most drug sellers are not involved in crime and polysubstance using drug sellers are in clear need of mental health services. Further, most drug sellers in this age range are White. Findings suggest that policy efforts that operate under the assumption of homogeneity of drug selling may be misguided.

    As most of the electric utilities in Germany have decided by now to adopt the multi-utility strategy for sales promotion in the open electricity market, a questionnaire has been distributed to 1 000 households in order to find out whether product bundling or cross selling in combination with the low-interest product 'electricity' is a good strategy to enlarge the customer basis. EFOplan (Munic University) and the consulting firm Accenture have been in charge of the survey. The results show the current status of insight of household customers and their motives to change supplier, as well as the pattern of demand for product bundling. (orig./CB) [German] Da mittlerweile die meisten EVUs eine Multi-Utility-Strategie anstreben, wurde mittels einer schriftlichen Befragung von 1 000 deutschen Haushalten untersucht, ob die Vermarktung von Zusatz- bzw.

    The increasing stringency of world food markets requires farmers to adjust farm structure and commercial strategies to remain integrated in export supply chains. The goal of this study was to identify and characterize different types of fresh fruit farms with regard to farm structural and commercial strategies for a representative sample of fresh fruit growers from central-south Chile exporting to world markets. A typology of farms was constructed based on multivariate analysis, according to which five types of farms were differentiated from five distinct factors. Cluster I comprised the smallest and uncertified farms (14.3% of the sample). The remaining four clusters comprised certified farms, but with different farm structural and commercial characteristics. Cluster II (15.1%) was composed of farms located further from market connections. Cluster III (23.9%) comprised farms with the highest number of fruit species, and consequently, more diversified in fruit production. Cluster IV (8.8%) was the smallest group, and comprised the largest firms. Finally, Cluster V (37.8%) was composed of highly specialized fruit farms, with the highest proportion of hectares dedicated to the production of a single fruit species. The results show the heterogeneity among fresh fruit farms and support the need for differentiated incentives and technological transfer schemes from the public sector and fruit companies in order to successfully keep farmers within export supply chains.

    Lactic acid fermentation represents the easiest and the most suitable way for increasing the daily consumption of fresh-like vegetables and fruits. Literature data are accumulating, and this review aims at describing the main features of the lactic acid bacteria to be used for fermentation. Lactic acid bacteria are a small part of the autochthonous microbiota of vegetables and fruits. The diversity of the microbiota markedly depends on the intrinsic and extrinsic parameters of the plant matrix. Notwithstanding the reliable value of the spontaneous fermentation to stabilize and preserve raw vegetables and fruits, a number of factors are in favour of using selected starters. Two main options may be pursued for the controlled lactic acid fermentation of vegetables and fruits: the use of commercial/allochthonous and the use of autochthonous starters. Several evidences were described in favour of the use of selected autochthonous starters, which are tailored for the specific plant matrix. Pro-technological, sensory and nutritional criteria for selecting starters were reported as well as several functional properties, which were recently ascribed to autochthonous lactic acid bacteria. The main features of the protocols used for the manufacture of traditional, emerging and innovative fermented vegetables and fruits were reviewed. Tailored lactic acid bacteria starters completely exploit the potential of vegetables and fruits, which enhances the hygiene, sensory, nutritional and shelf life properties.

    Full Text Available In 2007 (the last agricultural census, Chile had 308, 445 ha of fruit orchards: an increase of almost 32% from the previous census (1997. The most important species were table grapes (20%, avocados (13% and apples (12%. Some 22% of the fruit crops growing area corresponded to juvenile orchards; within the species with higher proportion of juvenile orchards were prunes (42% and blueberries (56%. Most orchards are located between latitude 27º18` S (Copiapó and 40º36´S (Puerto Varas. The industry is driven by the export component which accounts for more than 50% of the fruits produced. In the crop season 2009-2010, approximately 254 million boxes (around 2.5 million tons were exported, representing over US$ 3.5 million. Processed and fresh fruits represented 8.2 and 26.7% of the total forest and agricultural Chilean exports in 2008, respectively. The main markets for this fruits were USA/Canada (42% and Europe (32%. The fruit grower receives, on average, 12-16% of the total price of the fruit in its final destination. Each year the fruit industry employs 450.000 people directly, of which 1/3 are permanent. Even though the fruit industry employs the highest proportion of the agricultural labor and the growing area has increased in the last 20 years, the proportion of agricultural employment has decreased from 19.5% in 1989 to 10.8% in 2008. It might also be noted that Chile invests only 0.7% of the GDP in research. In the last 40 years, the fruit industry has been a motor for the Chilean economic development, but the lower rates of currency exchange, the rising costs of energy (oil, electricity, and the increasing scarcity of hand labor have drastically reduced the profitability and are putting at risk the viability of a large proportion of the fruit orchards in Chile. It is estimated that this season around 65% of the orchards will have a negative economic balance in their operations. Higher investment in research, improvements in fruit quality

    Full Text Available Iodine is an essential microelement for humans and iodine deficiency disorder (IDD is one of the most widespread nutrient-deficiency diseases in the world. Iodine biofortification of plants provides an attractive opportunity to increase iodine intake in humans and to prevent and control IDD. This study was conducted to investigate the iodine uptake and accumulation in edible portion of two fruit trees: plum and nectarine, and two horticultural crops: tomato and potato. Two type of iodine treatments (soil and foliar spray application, and, for fresh market tomato, two production systems (open field and greenhouse hydroponic culture were tested. The distribution of iodine in potato stem and leaves, and in plum tree fruits, leaves, and branches was investigated. Iodine content of potato tubers after postharvest storage and processing (cooking, and iodine content of nectarine fruits after postharvest storage and processing (peeling were also determined. Differences in iodine accumulation were observed among the four crops, between applications, and between production systems. In open field, the maximum iodine content ranged from 9.5 and 14.3 μg 100 g−1 for plum and nectarine fruit, to 89.4 and 144.0 μg 100 g−1 for potato tuber and tomato fruit, respectively. These results showed that nectarine and plum tree accumulated significantly lower amounts of iodine in their edible tissues, in comparison with potato and tomato. The experiments also indicated hydroponic culture as the most efficient system for iodine uptake in tomato, since its fresh fruits accumulated up to 2423 μg 100 g−1 of iodine. Iodine was stored mainly in the leaves, in all species investigated. Only a small portion of iodine was moved to plum tree branches and fruits, and to potato stems and tubers. No differences in iodine content after fruit peeling was observed. A significant increase in iodine content of potato was observed after baking, whereas a significant decrease was

    Full Text Available Fresh-cut fruits and vegetables have longer shelf lives when appropriate packaging materials having proper permeability properties are used. For this reason eight different packaging materials having different permeability properties were used and it was aimed to determine the appropriate packaging material and analytical and mathematical shelf lives of fresh cut red cabbage. Head space analysis, microbiological and sensorial analysis together with pH, weight loss (% and colour analysis were performed. As a result of the study, it was determined that low density polyethylene (LDPE film having 20 µm of thickness and 12276 cc/m2-day of oxygen permeability was determined as the most suitable packaging material for packaging of fresh-cut red cabbage. Mathematical microbiological shelf life was determined as 12.33 days and both analytical microbiological and sensorial shelf lives were determined as 12 days. It was shown that Gompertz equation can be used in determination of microbiological shelf life of fresh-cut red cabbage since the analytical and mathematical shelf life results fit to each other. Also, the equation that can be used in calculation of shelf life of fresh-cut red cabbage when packaged with AYPE film having 12276 cc/m2-day oxygen permeability was determined as log(Nt/N0 = 6,83 × exp{-exp{[(0,80*e(6,83-t/6,83]+1}}.

    A healthy diet is an important factor in a healthy lifestyle that is becoming increasingly important in today's society. The fruits of European elder (Sambucus nigra L.) are a rich source of bioactive compounds like anthocyanins. In this study, dried and fresh fruits of four cultivated and six wild growing plants were investigated for their anthocyanin pattern and content as well as their bioactive compounds. After separation on HPTLC plates silica gel 60 F254 with a mixture of ethyl acetate, 2-butanone, formic acid and water, the plates were quantitatively evaluated by densitometry and also subjected to various (bio)assays to investigate the samples for compounds acting as radical-scavengers, antimicrobials, estrogens, and acetylcholinesterase or tyrosinase inhibitors. The mean contents for the two most abundant anthocyanins in European elderberries, confirmed by HPTLC-ESI-MS, ranged from 159 to 647mg/100g in fresh and from 166 to 2764mg/100g in dried fruits for cyanidin-3-sambubioside, and from 112 to 521mg/100g in fresh and 95 to 226mg/100g in dried fruits for cyanidin-3-glucoside. Additionally, the anthocyanin content was higher in berries of cultivars than of wild growing plants. The anthocyanins' radical scavenging activity and antimicrobial effect against Aliivibrio fischeri were confirmed. Further, a radical scavenging compound affecting A. fischeri and acting as acetylcholinesterase inhibitor was tentatively assigned by its protonated molecule at m/z 456 as either ursolic or oleanolic acid by HPTLC-ESI-MS. HPTLC hyphenated with bioassays and mass spectrometry was selected as method of choice for fingerprinting, pattern recognition, and bioprofiling of elderberry samples as well as quantitation and confirmation of bioactive compounds therein.

    Understanding the environmental impacts of fruit production will provide fundamental information for policy making of fruit consumption and marketing. This study aims to characterize the carbon footprints of China's fruit production and to figure out the key greenhouse gas emissions to cut with improved orchard management. Yearly input data of materials and energy in a full life cycle from material production to fruit harvest were obtained via field visits to orchards of five typical fruit types from selected areas of China. Carbon footprint (CF) was assessed with quantifying the greenhouse gas emissions associated with the individual inputs. Farm and product CFs were respectively predicted in terms of land use and of fresh fruit yield. Additionally, product CFs scaled by fruit nutrition value (vitamin C (Vc) content) and by the economic benefit from fruit production were also evaluated. The estimated farm CF ranged from 2.9 to 12.8 t CO2-eq ha(-1) across the surveyed orchards, whereas the product CF ranged from 0.07 to 0.7 kg CO2-eq kg(-1) fruit. While the mean product CFs of orange and pear were significantly lower than those of apple, banana, and peach, the nutrition-scaled CF of orange (0.5 kg CO2-eq g(-1) Vc on average) was significantly lower than others (3.0-5.9 kg CO2-eq g(-1) Vc). The income-scaled CF of orange and pear (1.20 and 1.01 kg CO2-eq USD(-1), respectively) was higher than apple, banana, and peach (0.87~0.39 kg CO2-eq USD(-1)). Among the inputs, synthetic nitrogen fertilizer contributed by over 50 % to the total greenhouse gas (GHG) emissions, varying among the fruit types. There were some tradeoffs in product CFs between fruit nutrition value and fruit growers' income. Low carbon production and consumption policy and marketing mechanism should be developed to cut down carbon emissions from fruit production sector, with balancing the nutrition value, producer's income, and climate change mitigation.

    Concentrated fruit products have a significant place in modern consumption markets and are valuable semi-prepared food components to the bakery, dairy, confectionary, canning, baby food, frozen food, distilling and beverage industries. There is continuous pressure on the beverage industry to improve the quality of concentrated fruit products in order for reconstituted fruit beverages to compete with beverages that are made from fresh fruits. In recent years, Alicyclobacillus spp. have become a major concern to the beverage industry worldwide as many high-acid, concentrated fruit products have been found to be contaminated with these spoilage microbes. The thermo-acidophilic nature of alicyclobacilli and highly resistant endospores allows for their survival during the production of concentrated fruit products. Under favourable conditions, endospores can germinate and multiply to numbers high enough to cause spoilage and product deterioration through the production of chemical taint compounds. It is imperative to understand the nature of Alicyclobacillus within the fruit concentrate processing environment so as to develop effective control strategies and to prevent spoilage in juice and beverage products that are reconstituted from fruit concentrates. This paper reviews the occurrence of alicyclobacilli in the fruit processing environment, control measures, as well as detection, identification and standardised test methods that are currently used for Alicyclobacillus in concentrated fruit products.

    At a Joint FAO/IAEA/WHO Expert Committee on Food Irradiation (JECFI) meeting held in 1976, recommendations were made to rationalize the unnecessarily elaborate wholesomeness evaluation procedures for irradiated foodstuffs. Irradiation at the commercially recommended doses did not adversely affect the constituents of mangoes, papayas, litchis and strawberries at the edible-ripe stage. These favourable radiation-chemical results justified the development of a theoretical model mango which could be used for extrapolation of wholesomeness data from an individual fruit species to all others within the same diet class. Several mathematical models of varying orders of sophistication were evolved. In all of them, it was assumed that the radiant energy entering the system reacted solely with water. The extent of the reaction of the other components of the model fruit with the primary water radicals was then determined. No matter which mathematical treatment was employed, it was concluded that the only components which would undergo significant modification would be the sugars. In order to extrapolate these data from the mango to other fruits, mathematical models of three fruits containing less sugar than the mango, viz. the strawberry, tomato and lemon, were compiled. With these models, the conclusion was reached that the theoretical degradation spectra of these fruits were qualitatively similar to the degradation pattern of the model mango. Theory was again substantiated by the practical demonstration of the protective effect of the sugars in the tomato and lemon. The decrease in radiation damage was enhanced by the mutual protection of the components of the whole synthetic fruits with ultimate protection being afforded by the biological systems of the real fruits

    Full Text Available Background: Fruits and vegetables are considered as the source of antioxidant and the factor of destroying reactive oxygen species. The effect of this antioxidant might decrease in time. This study was aimed at examining and comparing the antioxidant effect and the level of phenolic and flavonoid compounds as well as allicin level, between fresh and three-month stale Allium sativum (garlic.Materials and Methods: In an experimental study, the ethanolic extract of bushes of fresh and three-month-old Allium sativum was prepared and their antioxidant activities were assessed in linoleic acid and β-carotene linoleate system. The amount of phenolic compounds was measured by Folin-Ciocalteumethod, based on gallic acid; the amount of flavonol and flavonoid compounds by aluminum chloride base on rutin base; and the amount of allicinby spectrophotometry method. SPSS-15 Software and t-statistic tests were used to analyze the mean difference between the results of two groups and p<0.05 was considered as significant. Results: The efficiency of fresh garlic (35.36 in inhibiting the oxidation was higher (p<0.05 comparing to three-month dated Allium sativum (10.2. Phenolic compounds of the fresh garlic (12.61mg/g were more than the three-month dated Allium sativum (2.89mg/g. The amount of allicin was respectively 15 µg/ml and 8 µg/ml in the fresh and three-month dated Allium sativum (p<0.05.Conclusion: The fresh garlic contains more useful substances and it is recommended to be used in its fresh estate.
