A Central de Abastecimento S.A. do Rio Grande do Norte (Ceasa-RN) se constitui enquanto uma institui??o, formada por uma infraestrutura, localizada no munic?pio de Natal-RN, que tem como objetivo abastecer o territ?rio com produtos hortifrutigranjeiros, entre outros alimentos. Atrav?s de suas intera??es espaciais, a central de abastecimento alimentar do RN, promove a converg?ncia de diversos circuitos espaciais de produ??o, e consequentemente se relaciona com os elementos dos circuitos da economia urbana (supermercados varejistas, hipermercados, supermercados atacadistas, feiras livres, mercados p?blicos, etc.) por meio dos fluxos divergentes da distribui??o de hortifrutigranjeiros. Nesse contexto, esta disserta??o tem como objetivo compreender em que medida ocorre a rela??o entre a Ceasa-RN e os circuitos da economia urbana na cidade de Natal. O caminho percorrido para atingir essa finalidade foi constitu?do de pesquisa bibliogr?fica, levantamento de dados atrav?s de documentos oficiais e institucionais, e de uma pesquisa de campo com entrevistas nos supermercados, hipermercados, atacadistas e Ceasa-RN e aplica??o de formul?rios nas feiras livres e mercados p?blicos. Os resultados da pesquisa mostraram que, no contexto da forma??o socioespacial do Brasil, as centrais de abastecimento alimentar foram criadas em meio a um processo de reestrutura??o do territ?rio, e da consolida??o dos circuitos da economia urbana. Os resultados apontaram tamb?m o alargamento das escalas provocado pelas centrais, atrav?s do caso das intera??es espaciais da Ceasa-RN na cidade de Natal, quando o entreposto de abastecimento converge os fluxos (nacionais, regionais e locais) de circuitos espaciais de produ??o agr?cola, ao mesmo tempo em que mant?m rela??es com os circuitos da economia urbana. Por fim, os resultados demonstraram, atrav?s do caso da Ceasa-RN, que as centrais de abastecimento alimentar se constituem em um agente misto dos circuitos da economia, n?o s? se relacionando com ambos os circuitos, o superior e o inferior, mas tamb?m, constitu?das por ambos, desempenhando e apresentando um papel h?brido

Full textAbstract:
The benefits of low UV dose treatment of horticultural produce – also known as hormetic treatment - have been attested to in numerous studies conducted over the last 15 years. However, commercial growers have not adopted the concept of hormesis. With increasingly stringent controls on the use of fungicides and other chemical agents the time has come to examine how hormetic treatment might be applied in the horticulture sector. The objectives of this work were firstly, to confirm UV-induced hormetic effects applied postharvest for a number of different types of produce, namely, tomatoes, broccoli, strawberries and mangoes. Secondly, to evaluate the use of rollers to ensure full surface treatment of produce, and thirdly to evaluate the possibility of treating produce preharvest. In order to investigate surface UV dose distributions, a polystyrene sphere (Diameter 70 mm) was used to simulate fruits such as tomatoes, apples, peaches etc., that have an approximately spherical form. Biodosimetry based on spores of Bacillus subtilis was employed to experimentally determine UV doses and to compare the results obtained with theoretical predictions. Good agreement was obtained and the modelling approach was extended to other types of produce. This showed the amenability of mechanical rollers to ensure full surface treatment of produce. Postharvest treatment of produce was carried using conventional low intensity UV sources principally emitting at 254 nm and also a commercially available high energy pulsed UV source. Treatment using the conventional UV source was carried out on mechanical rollers within a UV cabinet designed for this work at a fixed distance from the source and at an intensity of 1000 μW/cm2. A 5 minute conventional UV treatment of tomatoes was approximately comparable to fruit given a 3-pulsed treatment using the pulsed source (507 J/pulse of polychromatic light). The colour and texture of both groups of fruit were significantly maintained as compared with controls. The treated tomatoes also showed a significant increase in the ascorbic acid levels during storage. Similarly, a 15 minute conventional UV treatment of broccoli heads was comparable to heads given a 10-pulsed treatment using the pulsed source. Where both treatments gave rise to a statistically significant retention of green colour of treated broccoli. In addition, mangoes given a 10 minute conventional UV treatment were comparable to fruit given a 20-pulsed treatment using the pulsed source with both treatments leading to maintenance of texture as compared to control fruit. This confirmed the UV-hormetic effects. The effects of conventional and pulsed treatments are compared and discussed. Preharvest treatment of tomatoes and strawberries was carried out in commercial glasshouses. Doses of either 3 or 8 kJ/m2 were delivered to the fruits using a treatment device designed for the work, which delivered a combined intensity of 2000 μW/cm2 from two low pressure UV sources. The treated tomatoes showed a delay in development of colour as measured on the vine and after picking. Picked tomatoes were inoculated with P. digitatum and C. gloeosporioides and the results obtained showed a significant inhibition of the development of the fungi in the treated fruit during the storage period. These results suggest that the beneficial response shown by the preharvest treatment is not a localised one but a systematically induced resistance observable throughout the treated plant. This was shown by monitoring tomato fruits on treated plants which themselves where not directly exposed to the UV light. The two doses elicited different responses in the treated strawberries, with the 8 kJ/m2 dose causing the fruit to redden significantly faster than the 3 kJ/m2 treated fruits and controls. This could have significant nutritional benefit as the red colour of strawberries has been correlated with anthocyanin levels. On the other hand, treatment at the lower UV dose led to a lag in colour development. The amenability of the equipment utilised for commercial application is discussed.

Full textAbstract:
Introduction: Little is known about dietary patterns among individuals with type 2 diabetes mellitus (T2DM) in Peru. This study aimed at determining whether there is association between glucosa metabolism disorder and consumption of fruits, vegetables and sweetened beverages.
Material and Methods: Secondary analisis of a population-based cross-sectional study conducted in Tumbes, a región in northern Peru. The outcomes variable were consumption of fruits, vegetables and sweetened beverages, defined by self-report, whilst the exposure was glucose metabolism disorder status (euglicemic, with T2DM bit not aware of diagnosis, and with T2DM and aware of diagnosis), defined by the oral glucose tolerance test. To assess the associations of interest, Poisson regression models with robust variance were created, and prevalence ratios (PR) and 95% confidence intervals (95% CI) were reported.
Results: A total of 1607 individuals, mean age 48.2 (SD:10.6); and 809 (50.3%) females, was enrolled. The prevalence of T2DM was 11.0% (95%CI: 9.5%-12.6%), and out of them, 105 (59.7%) had previous diagnosis. Only 213 (13.3%) reported consuming sweetened beverages > once/week, whilst 409 (25.5%) and 736 (45.8%) reported consuming vegetables and fruits, respectively. Those with previous T2DM diagnosis had lower probability of consuming sweetened beverages (sometimes vs. never: PR=0.57; 95%CI: 0.41-0.78, and >once/week vs. never PR=0.39; 95%CI: 0.18-0.85). Both the consumption of fruits and vegetables were similar among those with and without previous T2DM diagnosis.
Conclusions: Compared to euglycemic subjects, individual with previous T2DM diagnosis had lower consumption of sweetened beverages, but such association was not present among those with T2DM but without previous diagnosis. Fruits and vegetables consumption were not different between the different glucose metabolism disorder categories.Introducción: Poco se conoce sobre los patrones de dieta de individuos con diabetes mellitus tipo 2 (DM2) en Perú. El objetivo del presente estudio fue determinar si existe asociación entre la alteración del metabolismo de la glucosa y ciertos patrones de dieta (consumo de bebidas azucaradas, verduras y frutas). Materiales y métodos: Análisis secundario de un estudio poblacional de tipo transversal realizado en Tumbes, en el norte del Perú. Las variables resultado fueron consumo de bebidas azucaradas, consumo de verduras y consumo de frutas, definidas por autorreporte; mientras que la exposición fue la alteración del metabolismo de la glucosa (euglicémico, con DM2 pero sin diagnóstico previo, y con DM2 y diagnóstico previo), basado en la prueba de tolerancia oral a la glucosa. Para evaluar las asociaciones de interés se crearon modelos de regresión de Poisson con varianza robusta y se reportaron razones de prevalencia (RP) e intervalos de confianza al 95% (IC 95%) Resultados: Un total de 1607 individuos, media de edad de 48 , 2 (DE: 10,6), y 809 (50,3%) mujeres, fueron enrolados. La prevalencia de DM2 fue de 11,0% (IC95%: 9,5% -12,6%), y de ellos, 105 (59,7%) tuvieron diagnóstico previo. Solo 213 (13,3%) reportaron consumir bebidas azucaradas> 1 vez / semana, mientras que 409 (25,5%) y 736 (45,8%) reportaron consumir verduras y frutas en forma casi diaria, respectivamente. Aquellos con diagnóstico previo de DM2 tuvieron menor probabilidad de consumir bebidas azucaradas (algunas veces vs.Nunca: RP = 0,57; IC95: 0,41-0,78 y> 1 vez / semana vs.Nunca: RP = 0,39 ; IC95%: 0,18-0,85). Ni el consumo de frutas ni el de verduras fue mayor en aquellos con o sin diagnóstico previo de DM2. Conclusiones: Comparados con los euglicémicos, los individuos con diagnóstico previo de DM2 tuvieron un menor consumo de bebidas azucaradas, pero dicha asociación no estuvo presente en aquellos con DM2 sin diagnóstico previo. El consumo de frutas y verduras no fue diferente entre las categorías de alteración del metabolismo de la glucosa estudiadas.

Full textAbstract:
Objectives: Among different factors, diet patterns seem to be related to depression. The aim of this study was to evaluate the association between the consumption of fruits and/or vegetables and depressive symptoms. Methodology/Principal findings: A secondary data analysis was conducted using information from a population-based survey from 25 regions from Peru. The outcome was the presence of depressive symptoms according to the Patient Health Questionnaire (cutoff 15 to define major depressive syndrome); whereas the exposure was the self-reported consumption of fruits and/or vegetables (in tertiles and using WHO recommendation 5 servings/day). The association of interest was evaluated using Poisson regression models controlling for the complex-sample survey design and potential confounders. Data from 25,901 participants were analyzed, mean age 44.2 (SD: 17.7) and 13,944 (54.0%) women. Only 910 (3.8%; 95%CI: 3.5%–4.2%) individuals reported consuming 5 servings of fruits and/or vegetables/day; whereas 819 (2.8%; 95%CI: 2.5%–3.1%) had depressive symptoms. Those in the lowest tertile of fruits and/or vegetables consumption had greater prevalence of depressive symptoms (PR = 1.88; 95% CI: 1.39–2.55) than those in the highest tertile. This association was stronger with fruits (PR = 1.92; 95%CI: 1.46–2.53) than vegetables (PR = 1.42; 95%CI: 1.05–1.93) alone. Conclusions: An inverse relationship between consumption of fruits and/or vegetables and depressive symptoms is reported. Less than 5% of subjects reported consuming the amount of fruits and vegetables recommended by the WHO. There is a need to implement strategies to promote better diet patterns with potential impact on mental health. © 2017 Wolniczak et al.

Full textAbstract:
This thesis begins with a background chapter which explores the current diabetes epidemic and examines the role of obesity and oxidative stress as causative factors. Current dietary recommendations for prevention of type 2 diabetes are critically evaluated. A systematic review and meta-analysis was conducted to determine the independent role of fruit and vegetables in preventing diabetes. Convincing benefit for greater consumption of green leafy vegetables was demonstrated. An insignificant trend towards benefit was observed for fruit and vegetables. The Fruit and Vegetable Intake and Glucose Control Study (FIVE) is a sub study of the Let’s Prevent Diabetes Study. FIVE includes cross sectional analysis of baseline plasma vitamin C, (a biomarker for fruit and vegetable intake) from 2101 participants. FIVE further includes 12 months analysis of individuals with impaired glucose regulation, randomised to receive group education or usual care. Results demonstrate 29% of the population consumed at least 5 portions of fruit and vegetables a day. Fewer South Asian individuals met the recommendation compared to White Europeans (21% vs. 30% p = 0.003). Each additional piece of fruit or vegetable consumed (21.8μmol/l plasma vitamin C) was associated with a reduction of 0.04% in HbA1c, 0.05mmol/l in fasting and 0.22mol/l in 2 hour blood glucose. Participants who consumed 5 portions a day compared to those who did not, had a 24% associated reduced risk of being diagnosed with impaired glucose regulation (OR = 0.76, 95% CI: 0.59 to 0.98). At 12 months follow up those receiving lifestyle education had greater levels of plasma vitamin C compared to those in the usual care arm (36.1μmol/l (SD 20.7) vs.29.9μmol/l (SD 20.3)). No statistical difference in mean change between intervention arms was seen. The thesis provides novel, robust nutritional biomarker data from a large at risk, multi ethnic population. Results support recommendations to promote fruit and vegetables in the diet to prevent diabetes. The potential for tailored advice on increasing green leafy vegetables among those at risk of diabetes should be investigated further.

Objective: To evaluate if fruits and vegetables consumption is associated with overweight and obesity in Peruvian adults and as to describe the sociodemographic profi le of the people with overweight and obesity. Subjects and methods: Populationbased study that used data from the National Demographic and Health Survey (DHSENDES) performed in the 25 regions of Perú. The outcomes were overweight and obesity assessed using the Body Mass Index, whereas the exposure variable was the fruit and vegetable consumption evaluated by self-report during the last seven days. Poisson regression models adjusted by potential confounders were used to evaluate associated factors with overweight and obesity, as well as the association of interest, reporting prevalence ratios (PR) and 95% confi dence intervals (95%CI). Results: Data from 4,641 participants, mean age 37.1 years (SD: 11.8) and 53.6% women, were analyzed. Only 220 (4.8%; 95%CI 4.1%-5.4%) individuals reported a fruit and vegetable consumption of ≥5 portions per day, whereas 1,818 (39.2%; 95% CI 37.8%-40.6%) had overweight and 865 (18.6%; IC95% 17.5%-19.8%) presented obesity. Factors associated with overweight and obesity included gender, age, education level, socioeconomic level, marital status, and hypertension diagnosis. No association was found between a greater fruit and vegetable consumption and overweight (p=0.98) or obesity (p=0.99). Conclusions: No evidence of association between overweight and obesity with fruit and vegetable consumption was found. Only 1 out of 20 individuals reported consuming the recommended amount of fruit and vegetables per day, whereas 60% had overweight and obesity.Revisión por pares

Full textAbstract:
Factors that affect liquid chemical intervention methods of controlling pathogens
on fresh-cut produce were investigated. The relationship between produce tissue
structure (intercellular space, cell size, and cell distribution) and the sanitizing
effectiveness of liquid chemical treatment was studied. Experiments determined if
sanitizer contact with bacteria could be improved through the use of surfactants and
different application methods (drop application method, negative pressure differential,
and sonication). To test these factors, a model sanitizer, H2O2, and a model
microorganism: Salmonella Typhimurium, along with various fresh-cut produce (apple,
pear, carrot, and potato) were tested. Microscopic analysis revealed a very complicated
pore structure consisting of irregular capillaries. S. Typhimurium was found to survive in
all produce tested, and washing did not significantly reduced inoculated bacteria
regardless of the bacterial incubation time or produce type. The results showed that a 3%
H2O2 solution reduced S. Typhimurium in produce and the solutionÂs efficiency varied in
the following descending order: potato>apple>carrot>pear. In seven min treatments,
bacteria were reduced by 2.5 CFU/ml in potato, 2.3 CFU/ml in apple, 1.5 CFU/ml in
carrot, and 0.7 CFU/ml in pear. There was no direct evidence on how intercellular space,
its percentage or cellular distribution and shape affected efficiency, but some possibilites
were discussed. The rate and extent of liquid penetration, and how varying pore
diameter in each cell or air space prevent complete chemical treatment penetration were
also analyzed.
It was determined that bacterial density has a slight effect in bacterial reduction
but this depends on type of produce inoculated. The use of surfactants did not improve
bacterial reduction in either washing or chemical treatments, and neither did the use of drop application method or temperature differential. On the other hand, applying the
chemical treatment with a surfactant while using a sonicator did improve the treatmentÂs
efficiency. This thesis provides a number of factors to be considered when designing a
chemical treatment and a guideline for further research in areas such as rate and extent of
liquid chemical treatment penetration into fresh-cut produce.

The Fresh Fruits and Vegetables Program is a federally funded program intended to increase public school students' fruit and vegetable consumption. The purpose of this mixed-method study was to evaluate the implementation of this program at a rural southwestern Title 1 elementary school to determine teacher perceptions of the program and whether the program met federal goals. Social ecological model and social cognitive theory grounded the investigation. The mixed method design included semi-structured interviews with 11 teachers accompanied by an anonymous web-based open response questionnaire and document reviews. Descriptive statistics were reported for Likert scale survey items and invoice documents to determine amount and variety of fruits and vegetables dispersed during the program. Interview data were open coded and analyzed for emergent themes. Teachers reported that the program initially provided a variety of produce, appropriate portions, and curriculum resources, which made the program a success. However, participants also noted that in the second and third years of implementation, their support for the program diminished due to declining quality, variety, and amounts of fruits and vegetables that negatively affected the achievement of program goals. Archival invoices supported these findings with decreased numbers of fruits and vegetables ordered in subsequent years. The findings were incorporated into an evaluation report for the local site. Implications for positive social change include providing the local administration with research-based findings on teachers' perceptions of the program, goal outcomes, and recommendations related to implementation at the local site.

Full textAbstract:
Drying is a process of moisture removal due to simultaneous heat and mass transfer. High hydrostatic pressure (HHP) processing subjects liquid and solid foods, with or without packaging, to pressures between 100 and 800 MPa. The application of HHP affects cell wall structures, leaving the cells more permeable, facilitating the diffusion and providing higher drying rates.
In this study, two variety of apples, i.e. Amasya and red delicious, green beans and carrots were pretreated with HHP at different pressure-time-temperature combinations (100 &ndash300 MPa for 5 &ndash
45 min at 20 and 35°
C) prior to drying. Hot air drying experiments were carried at different temperatures (27, 45, 65, and 85°
C) and air velocity of 0.4 and 0.8 m/s. To obtain the drying data, samples were subjected to hot air drying under constant external conditions. The applicability of 14 kinetic models selected from the literature for the drying of fruits and vegetables was determined by appropriate statistical analyses procedures. Improving the drying conditions by increasing the drying temperature generally masked the effect of HHP pretreatment on drying rate. Only for green beans, HHP treatments at 20°
C decreased the drying rate. Generally pressures of HHP pretreatment higher than 100 MPa caused cell permeabilization resulted in higher drying rates for apples and carrots. Among the 14 models, modified Page model for apples, and modified Page and two term exponential models for green beans and carrots were found to best explain the drying behaviors.

Background: Along with the rapid economic development in China, some associatingproblems emerged, such as inflation. Especially for the daily consuming fresh fruits andvegetables (FFV), the price goes up at very fast speed, which draws a lot of publicattention on it. Farmers are discouraged and hurt by the low vegetable prices. However,end consumers are complaining about the high vegetable prices. A consensus is reachedthat the problem behind this phenomenon exists in the "distribution links".Aim: How is the current status of FFV distribution system of supermarkets in China?What factors do influence the efficiency and cost of the system? How is theimplementation of ASD in China and what are the advantages and barriers? Should it beimplemented widely? If yes, what are our recommendations to improve it?Definition: Agricultural super-docking is a new method of supply and distribution offresh agricultural products from farmers to supermarkets directly, by signing anagreement of intent between farmers and merchants, in order to build an efficientplatform for quality agricultural products to enter the supermarkets. The essence of ASDis to dock the thousands of small farmers and the different supermarkets to build anintegrated production and marketing chain to gain benefit for merchants, farmers andconsumers at the same time.Completion and results: It is a complex task to improve the efficiency of FFVdistribution system of supermarkets in China and there is a long way to go to implementASD successfully and widely since this market is at the starting stage and immature.

Agricultural products cause many unnecessary losses in the process of market supply, including ugly vegetables and fruits. they don't conform to market specifications because of their shape, but whose nutritional value and delicacy remain unchanged. This waste of vegetables and fruits has already appeared in France, Britain, Hong Kong, Taiwan and other places, which is enough seriousness. In the process of discussing ugly fruits and vegetables, this study learned that in the production and consumption market, due to consumer awareness of agricultural products and strict market classification standards, it led to improper discarding and caused food waste. Social enterprise is important to emphasize the responsibility of protecting in the whole environment and help people in need, so there are many brands of ugly fruits and vegetables related to social enterprises. They not only use ugly fruits and vegetables to make nutritious, healthy or practical commodities for sale, but also use promotion and marketing methods to make the brand have a unique personality in the competitive market, so that the brand image of ugly vegetables and fruits can be improved and create new commercial value. This author will further explore the methods of brand image and collage design in order to solve ugly vegetable and fruit issues through visual design. understand the extended positioning and planning of ugly vegetable and fruit brand image through creative case analysis. Creative works is hoped that the positive image of ugly vegetable and fruit in consumers mentality , besides solving excessive food waste. It can also play a great role in the maintenance of the overall environment and ecology.

With the popularity of health awareness, there are more and more software and hardware that can help people record diet and measure calorie. Traditional written records, electronic barcode and measureing calorie with look-up table became incovenient. With the popularity of smartphone, the way using image recognition to record personal diet and measure calorie become a more convenient and high accuracy choice. Vegetable and fruit recognition is a image recognition method using vegetable and fruit images. Because we use hand to measure food weight, we do not have to prepare the other measuring tools. In the thesis, we take photos of vegetable and fruit with smartphone, then we extract color features, shape features and texture features with technology of image processing. The matching rate of our method is 98.5% and the error rate of calorie measurement is 4.5%. Compare to other food regocnition method[23],our method use less kind of features ,but we have higher matching rate (98%>95%) based on same SVM kernel(RBF). It is obvious that our method of vegetable and fruit recognition is higher accuracy and convenient method.

Taiwan vegetable & fruit wholesaler industry is the heart of Taiwan vegetables & fruits’ terminal and transportation. This industry can be traced back to the period of Japanese occupation. With the development of Taiwan transportation and the establishment of the farmer’s association, the transporting and selling form constantly transforms and continues using till now. We analyze the external environment of the vegetable & fruit wholesaler in Taiwan, and the different forms of vegetable & fruit wholesalers’ transporting and selling ways, and the difference among them. We consider that whether the transformation of consumption pattern, the agricultural investment from enterprises, and the appearance of electronic commerce would influence the wholesaler’s sales volume and sales pattern. We also consider the necessity of the transformation. We interpret the industry overview of Taiwan vegetable & fruit wholesaler from the study background and study purpose. We take the definitions discussed in the vegetable & fruit wholesaler literature, the theory of five forces analysis, and the theory of resource-based view as the base of our interview questionnaire. We interpret the difference of each kind of vegetable & fruit wholesaler’s overall transporting and selling pattern by participant observation. We interview three vegetable & fruit wholesalers by qualitative research method, and analyze the results. At the end, we combine the results with the findings in the literature, and propose the competitive resource which different kind of vegetable & fruit wholesaler own and different strategies taken to face the external environment.

Fruits and vegetables contain many phytochemicals. The phytochemicals could be a reducing agent, donator of hydrogen or electron and scavenger of oxygen species. In addition, it has antioxidant ability to scavenge free radical and reactive oxygen species and protected molecule to avoid injuring by oxidative stress in cell. Therefore, the vegetables and fruits are good sources of antioxidant in dietary. The study of this research focused on measuring the content of antioxidant compounds and total antioxidant capacity of 32 varieties of fruits and 32 varieties vegetables bought from three local markets. The result showed that the content of vitamin C in fruits and vegetables are between 9.55mg/100g to 160mg/100g. Amongst the commodities, the leafy vegetables as well as the fruits and vegetables colored in yellow, red and orange have abundant of carotenoids. The content of phenolic compounds in fruits and vegetables are between 14 mg/100g to 596.97mg/100g. Interestingly, only few varieties of fruits and vegetables could determine the content of anthocyanins. This is due to most of the anthocyanins are rich in the peel of fruits and vegetables. The total antioxidant capacity of fruit and vegetable commodities were measured by TEAC (Trolox equivalent antioxidant capacity) assay and the results were expressed by Trolox (6-hydroxy-2,5,7,8-tetramethylchroman- 2-carboxylic acid). The fruits and vegetables contains higher TEAC than 5 mmol of Trolox/g are including szjou persimmon, durian, strawberry, guava, pomegranate, atemoya, sweet cherry, passion-fruit, delicious apple, granny smith apple, carambola, kiwi fruit, golden kiwi fruit, sweet potato leaf, yellow sweet pepper, spinach, red sweet pepper, snow pea and asparagus. The antioxidant capacity of these fruits and vegetables were also measured by DPPH (α,α-diphenyl-βpicrylhydrazyl) assay, which is used to measure the radical scavenging activity in methanol extracts of tissue sample. The result showed that the antioxidant capacity of majority of fruits and vegetables examined by DPPH assay are similar to TEAC assay. The comparison analysis of the content of antioxidant compound and total antioxidant capacity were carried out in different cultivars of guava, wax apple, Indian jujube and pitaya. The content of antioxidant compound and total antioxidant capacity are different significantly in different cultivars. The study also analyzed the content of antioxidant compound and total antioxidant capacity in different parts of fruit including nectarine, sand pear, grape and apple. There were significantly different in the content of antioxidant compound and total antioxidant capacity in different parts of fruit. The antioxidant capacity in peel is higher than that in pulp of fruits. The seed of grape contain abundant of phenolic compounds, which is a very good source of antioxidant.

Increase in consumption of fresh cut produce over the past decade has resulted in
a rise in incidents of food borne outbreaks due to pathogens. Conventional techniques of
sanitizing washes may not be effective since the organic matter released from the fresh
produce use up the free chlorine thus reducing the sanitizing potential of wash water just
when it is needed most and a heat treatment step to kill pathogens cannot be applied if
the purpose is to consume fresh produce. Electron beam (e-beam) irradiation was used to
treat cut cantaloupe, cut roma tomatoes, baby spinach, romaine lettuce which were
surface inoculated with a cocktail of Salmonella and E. coli O157:H7. Results showed
that irradiation reduced Salmonella and E. coli O157:H7 significantly with increasing
doses at 0.2, 0.4, 0.6, 0.8, and 1.0 kGy. The D10-value for Salmonella on irradiated cut
cantaloupe, cut roma tomatoes, baby spinach, and romaine lettuce was found to be 0.71
kGy, 0.64 kGy, 0.19 kGy, and 0.23 kGy respectively. The D10-value for E. coli O157:H7
on the produce listed above was found to be 0.73 kGy, 0.54 kGy, 0.18 kGy, and 0.20
kGy respectively.
Low dose e-beam irradiation was found to be an excellent tool for ensuring the
reduction of spoilage organisms and extending shelf life in cut cantaloupe, cut roma
tomatoes, baby spinach, romaine lettuce, strawberries, and green onion. The produce
were tested for 12 days of storage for aerobic plate count, yeast and mold, lactic bacteria,
color, texture, and respiration rate as a function of irradiation doses 0, 1, 3, and 5 kGy.
Aerobic plate counts, yeast counts, and lactic acid bacteria were reduced appreciably at
all doses tested on all commodities. Molds did not grow on any samples including
control for cut cantaloupe, cut tomatoes, and green onion but for the other commodities,
mold was reduced at the same rate as yeasts and vegetative bacteria. Lactic acid bacteria
were reduced at all doses while the reduction was highest with 5 kGy in all commodities.
When irradiated with 5 kGy, during storage, strawberries, spinach, and green onion
displayed wet, soggy and mushy appearance, romaine lettuce leaves were wilted, had a
translucent midrib and brown pigmentation. E-beam irradiation increased respiration rate
for all samples on day 0 compared to non-irradiated control irrespective of the
commodity type and the effect was dose dependent. Firmness reduced appreciably for
cut roma tomatoes, baby spinach, strawberries, romaine lettuce, and green onion with
increasing doses. Cut cantaloupe was low in firmness but the effect was not dose
dependent.
Irradiation at low doses is a promising tool to reduce pathogens and enhance
keeping quality of cut cantaloupe, cut tomatoes, baby spinach, romaine lettuce,
strawberries, and green onion. Irradiation is to be implemented as part of an overall
HACCP plan and is not meant to replace existing control measures.

In this paper, use data envelopment analysis how to select the most efficient fruits and vegetables, to give consumers buying guide about fruits and vegetables. This study was funded by the Department of Health and Agriculture Committee established about Taiwan food nutrition database to retrieve from September 2011 to August 2012 includes 98 kinds of vegetables, 116 kinds of fruit nutrients(dietary fiber, vitamins A, E, B1 ... and other 14 kinds of nutrients), another by private companies commissioned by the Agriculture and Food Agency, Council of Agriculture handle the Taiwan "agricultural trading market Website" capture the average monthly price of fruits and vegetables, using data envelopment analysis on how to spend the least money, to get from fruits and vegetables daily basic needs of nutrients. Here, in the country, we found part of the rhizome vegetables, leafy vegetables, flowered fruit vegetables relatively efficient and mushroom are less efficient. Part of the berries in fruits, melons, orange fruit relatively efficient, but because the vast majority of pome fruits are imported goods are relatively inefficient. It takes the first layer visible (most efficient) compared with other layers to spend the less money, vegetables less expensive than fruits. At the Seasons, the result of vegetables is insignificant. Fruit because of its large seasonal variations in the results. Because summer typhoon invading Taiwan to spend the most expensive fruits and vegetables in the summer. In the partition part, little difference between the results of vegetables. Different results because of regional fruits, efficient vegetables due mostly concentrated in the central place of origin, it is central to spend most inexpensive fruits and vegetables. Therefore, the most inexpensive cost of fruits and vegetables is in central.

During the Food Security related issues have been highly emphasized in recent years, consumers require higher standard for the quality of foods. The application of “Food Traceability System” has also promoted to preserve the traceability of foods for publics. In addition, numerous Food Security regulations were established to protect publics from unqualified foods. Since low-temperature products are temperature-sensitive products, perishable and fragile with short period of shelf life, the logistics in cold chain management has gradually become the trend which was developed to maintain the complexity of products. Among a variety of low temperature products, fresh fruits and vegetables have the most frequent connections to our daily. Consumers also changed their shopping style from bulk purchase into various and small amount of purchase. Under the circumstances, this research purposed the principles for storing different products into same storage boxes. The principles are based on inducting key factors which would change the quality of fresh fruits and vegetables; sorting products based on different conditions of loading and storage environment. For dealing with fruits and vegetables turned into various and small amount situation, the “optimal model of consolidation decision for fresh vegetables and fruits”, based on Binary Integer Programming (BIP), is constructed to consolidate fresh fruits and vegetables under grading system through testing simulated samples. The conclusion of the analysis, has shown, the objective value and product surplus value have a significant impact when products are in different temperatures that cause variable shelf life results. The quality of products would be overrated that leads to false decisions when ethylene, a gas to accelerate the ripening, was ignored in the process of consolidating fresh fruits and vegetables. To sum up, if the variations of shelf life can be predicted precisely, false decisions would be avoided and products would preserve its optimal value, in order to increase overall profit for businesses of the third party logistics.

The purpose of this study was to revise the Lunch Box Program using the Intervention Mapping process to design a program for parents of preschool age children in the childcare setting. Program development was guided by input from group interviews (n = 3) that were held with parents (n = 31) at three child care centers. Four major themes were revealed 1) interest in receiving information in written format; 2) activities that stimulate parent interaction; 3) workshops and activity stations; and 4) recommendations for support from local supermarkets. Lunch Is In The Bag emphasizes packing fruits, vegetables and whole grains in lunch daily.
In a quasi-experimental design, six childcare centers were paired by size before being randomly assigned to intervention (n=3) and comparison (n=3) groups. The parents with primary lunch packing responsibility for the three to five year old children were enrolled as parent-child dyads. Primary outcome measures included lunch contents of fruits, vegetables and whole grains. Secondary outcome measures included change in behavioral constructs and process outcome measures included fit of program into operations and curriculum.
A total of 132 parent-child dyads completed the study, 81 in the intervention group and 51 in the comparison group. Direct observation of children’s lunches from the intervention group showed a significant increase in predicted mean number of servings of vegetables, from 0.41 to 0.65 (P < 0.001) and whole grains, from 0.54 to 1.06 (P < 0.001), but not fruit.
The intervention demonstrated a significant effect on knowledge of meal patterns (p = 0.010); outcome expectations for packing whole grains (p < 0.001); and subjective norms for packing fruit (p = 0.002), vegetables (p = 0.046), and whole grains (p = 0.015). Perceived behavioral control (p = 0.000), expectations (p = 0.007), and intentions (p = 0.048) were significant independent predictors for packing vegetables. Knowledge significantly predicted packing whole grains (p = 0.000).
Process outcome data indicated Lunch is in the Bag was a feasible nutrition education program that fit well into both the childcare center operations and curriculum.text

Flavonoids are phytochemicals possessing antioxidative properties. They are abundant in fruits and vegetables. This review article summarizes properties of flavonoids concerning their distribution in plants, catabolism, and the structure-activity relationships. Flavonoids act as antioxidants via their free radical scavenging activity. They also inhibit lipid peroxidation, lower blood cholesterol level, and decrease atherosclerosis and cardiovascular diseases. Flavonoids are anticarcinogenic, while some flavonoids have estrogen-like activities. Uptake of dietary antioxidative agents to decrease the risk of cancer, cardiovascular, and other diseases plays an important role in preventive medicine.

Quality measurement and pre-sorting of vegetables and fruits before on market are important in post harvest processes of agricultural products. In this study, impact force is applied to study firmness of fruits and vegetables nondestructively, and then compared with firmness by compression tests. Test materials are cherry tomato, sour plum, grape fruit, chinese peach and plum. The proper impact parameters highly correlating to firmness of these vegetable and fruits are explored from their impact force-time curves both in time and frequency domain. From the study, the time domain parameters C1 (maximum impact force / time of maximum impact force), C2 (maximum impact force / square of time of maximum impact force), tp (time of maximum impact force), tc (impact time) and tp/tc (skew of impact force-time curve) have correlation with maturity of these fruits and vegetable. The sensitivity of each parameter reflecting ripeness change of fruits and vegetable are different.

This study revises the issue of that the organic fruits and vegetables are usually discarded since their bad appearances, which causes tons of waste every year. On the other hand, a series of food scandals have emerged the distrust of food suppliers, and made the organic food the rock star in the market. However, there is still no any authentic and unified certification of organic food that severely challenges the organic food suppliers. Due to the issues that mentions above, this study purposes a new pattern of sharing economies themed “Transaction platform of unselected organic fruits and vegetables”, trying to solve the problems. By giving incentives to both sides of players—the organic farmers and consumers, platform can stimulate the transactions occurred. With other value-added services provided (e.g. authentic certification, well-designed mechanism of compensation, and resources efficiently allocation), the platform also purposes to figure out how a such business platform to develop continuously by high quality, low prices, and well-organized after-sale services in unselected organic fruits and vegetables transactions. At last, this study reconstructs the system and finds out the applied scenarios and additional values by “Vision, Position, Scenario Framework” and “Value Creation Cycle”. The platform is able to achieve self-sufficient, stable operation, and Pareto-improvement that continuously creating additional value to society.

In order to maintain the quantity, quality, and economic development of agricultural products, the applications and residues of pesticides have become important food safety and environmental protection issues in Taiwan. In this thesis, we used sampling data about vegetables and fruits in fields and wholesale markets of Taiwan’s Agricultural and Food Agency to figure out the crucial factors that would result in testing failure. The outcome shows that excessive pesticide application is the main reason of pesticide residues in Taiwan. Moreover, the production environment and the pesticide risk barely affect Taiwan’s pesticide residues in vegetables and fruits. Besides, to figure out which factor is related to the risks of those pesticides used in Taiwan, we used pesticide safety information of Taiwan’s Bureau of Animal and Plant Health Inspection and Quarantine as well as referencing the pesticide tax system of Norway to establish a pesticide risk framework that can fit the situation in Taiwan. The outcome shows that Maximum Residue Limits (MRLs) and the spraying habits of farmers have negative relation to the risks of those pesticides used in Taiwan.

The burden of obesity-related illness, which disproportionately affects low income households and historically disadvantaged racial and ethnic groups, is a leading public health issue in the United States. In addition, previous research has documented differences in eating behavior and dietary intake between racial and ethnic groups, as well as between urban and rural residents. The coexistence of diet-related disparities and diet-related health conditions has therefore become a major focus of research and policy. Researchers have hypothesized that differences in eating behavior originate from differing levels of access to and affordability of healthy food options, such as fresh fruits and vegetables. Therefore, this dissertation examines the affordability of fresh produce in the Brazos Valley of Texas.
This study uses information on produce prices collected by taking a census of food stores in a large regional area through the method ground-truthing. These are combined with responses to a contemporaneous health assessment survey. Key innovations include the construction of price indices based on economic theory, testing the robustness of results to different methods of price imputation, and employing spatial econometric techniques.
In the first part of the analysis, I evaluate the socioeconomic and geographical factors associated with the affordability of fresh fruits and vegetables. The results based on Ordinary Least Squares (OLS) regression show that except housing values (as median value of owner-occupied units) and store type, most factors do not have significant effects on the prices for these food items. In addition, the sizes and signs of the coefficients vary greatly across items. We found that consumers who pay higher premiums for fresh produce reside in rural areas and high proportion of minorities neighborhoods. We then assess how our results are influenced by different imputation methods to account for missing prices. The results reveal that the impacts of the factors used are similar regardless of the imputation methods. Finally we investigate the presence of spatial relationships between prices at particular stores and competing stores in the neighborhoods. The spatial estimation results based on Maximum Likelihood (ML) indicate a weak spatial correlation between the prices at stores located near each others in the neighborhoods. Stores selling vegetables display a certain level of spatial autocorrelation between the prices at a particular store and its neighboring competitors. Stores selling fruits do not present such relations in the prices.

Insufficient intake of fruits and vegetables (F&V) correlates closely with the occurrence of chronic diseases. There are many factors that may influence the F&V intake behavior. Present study attempts to understand this behavior from the perspectives of psychosociology, and to examine the relationships between F&V intake behavior and psychosocial-related factors. The subjects were selected by convenience sampling method. A total of 237 subjects (89 males and 148 females), employee in the government agency in Southern Taiwan, were recruited in this study. Based on psychosocial theories, including Health Belief Model, Theory of Planned Behavior, and Social Cognitive Theory, the survey questionnaire was developed and used as measuring tool to collect data. The results showed the intake of F&V was insufficient since there were 75.4% of subjects whose daily consumption of F&V less than five servings. Attitude (β=1.272，p=<0.05) is the psychosocial factor influencing total F&V intake. Besides, fruit intake was affected by perceived susceptibility （β=0.526，p=<0.01）and attitude(β=0.927，p=<0.01), and vegetable consumption was affected by behavioral intention (β=0.824，p=<0.05). In application, the influencing psychosicial factors may serve as an important reference while implementing nutrition education intervention or conducting consultation to help individual dietary modification.

Due to the globalization of the supply chain of fruits and vegetables, many fruits and vegetables in Taiwan have been exported to foreign countries. The first condition is that the quality of fruits and vegetables which transport a long time can still be accepted by retailers and consumers. And the atmosphere storage technology is used to extend the shelf life of fresh fruits and vegetables products. The atmosphere storage technology is the method that reduces the oxygen and increase carbon dioxide in the air to reduce fruit and vegetables product’s respiration rate of metabolism in order to prolong the storage duration. In Taiwan, on the supply side, there are many small-scale farmers.Their amount of goods are usually too small, less than filled the entire cabinet, so that can not be exported; On the demand side, the consumers also changed their shopping style from bulk purchase into various and small amount of purchase. Under the circumstances, this research purposed the principles for storing different products into same storage boxes. The principles are based on inducting key factors which would change the quality of fresh fruits and vegetables; sorting products based on different conditions of loading and storage environment. Focus on two parts: place of origin-logistics centers and logistics centers-retailers of fruit and vegetable supply chain, considering separately applicated to controlled atmosphere storage(CA) and modified atmosphere package(MAP) to extend the shelf life. For dealing with fruits and vegetables turned into various and small amount situation,using integer non-linear programming (INLP) methods to construct a "Consolidation Optimaztion for Fresh Fruits and Vegetables with Atmosphere Storage Technology". Through the simulated sample data, solve the consolidation optimaztion for fresh fruits and vegetables with atmosphere storage technology under consideration classification system. Finally, do some sensitivity analysis to several important parameters of modes: temperature, atmosphere setting costs, packaging costs, container using costs and shelf life prediction, expecting to identify important factors that affect the objectivity fo the model.

Abstract Student ID：N9931017 Title of Thesis：Impact of eating raw organic fruits and vegetables in Taiwan’s environment Total Pages：87 Name of Institute：National Pingtung University of Science and Technology Name of Department：Department of Environmental Science and Engineering Date of Graduation：July, 2012 Degree Conferred：Master Name of Student：Ruey-Shwu Lin Adviser：Dr. Jia-Twu Lee The Contents of Abstract in this Thesis： In Taiwan, recent news has come out about the effect of plasticizing and chemical clouding agents that have been used and consumed here for more than 30 years. Chemical additives are a part of every aspect of life, including diet. Cancer has been the number one cause of death in Taiwan for 29 consecutive years, with more than 40,000 people dying of cancer each year. In 2010, the Taiwan National Health Insurance Bureau medical costs for cancer was 11.7 billion NT dollars, creating a huge economic burden. Meanwhile, much damage is done to Taiwan's environment through the use of vast amounts of toxic substances, including antibiotics, hormones, anti-inflammatory drugs, and pesticides. These also enter our bodies via our food intake. This is detrimental to our personal health, family happiness, and medical health care system, with health insurance being a huge burden to the government. This study lasted 1.5 years, with experiments on a group of human subjects. The results show that this method is effective and easy to implement. Following this method will have a positive impact on Taiwan's overall environment, while reducing the expenditure of the National Health Insurance Bureau in Taiwan: For 5 days a week, each person consumes specific organic raw fruits and vegetables for lunch, abstaining from meat in this meal entirely. This strengthens the immune system due to the plentiful and balanced nutrition, which is not lost due to cooking. In turn this leads to a gradually enhanced level of personal health, reducing the expenditure of the BNHI in Taiwan. The raw organic vegetables and foods eaten in this meal plan weigh very little; thus if eaten by each person 5 days a week, much food could be saved, reducing the burden to the global food supply. This method also reduces the need for disposable chopsticks, plastic disposable tableware, detergent and large amounts of water for cleaning as there is no cooking involved, thus further benefiting the environment. In addition, this eating method helps change the blood from acidic to alkaline, with the result that eating meat becomes less desirable. Science has confirmed that meat reduction promotes good health. With more people eating raw organic fruits and vegetables, there would be more demand for organic food production, thus benefiting the natural ecology and the health of the people, while reducing environmental pollution, food intake, costs to the Taiwan National Health Insurance Bureau, and even global warming.

Although life expectancy is increasing due to the development of modern medication, humankind is still threatened with various illnesses. The key elements of illness and aging of human were accumulating free radical and reaction oxygen species (ROS) produced during the metabolism. Therefore, how to protect against oxidation, or cellular damage caused by free radicals and oxidative damage has become a crucial issue for maintaining a good quality of health nowadays. Vegetables and fruits are rich in phytochemicals, giving them an antioxidant capacity, making them effective in removing the free radicals and ROS. Especially, the deeper in the color of vegetables are the more antioxidant capacity they have. The purpose of this research was to compared the antioxidiative properties of dark-colored vegetables and fruits in terms of the total phenolic content (TPC), reducing power, and DPPH scavenging capacity. In this study, seven vegetables and six fruits were measured for TPC, reducing power and DPPH scavenging activity. Preliminarily results suggested that the vegetables bearing more TPC and exhibited more reducing power than fruits. The average TPC were 12 mg and 10 mg GAE/g for dark-colored vegetables and fruits, respectively. Parallelly, the reducing power for dark-colored vegetables was over 34 mg Vit. C/g. The higher in TPC, is the more reducing power was seem. Both dark-colored vegetables and fruit shown a remarkable high DDPH scavenging activities. The average DDPH scavenging capacity for dark-colored fruits and vegetables were found to be 91.44±0.55% and 80.47±0.54%, respectively. In summary, the dark-colored fruits and vegetables, such as purple cabbages and deep red cherries, had the highest antioxidant capacity, followed by deep-green broccoli, asparagus, and kiwi and finally orange or yellow colored pumpkins, carrots, papaya, mango and dragon fruit. The antioxidant capacity is higher when the color of fruits and vegetables are deeper. The results on antioxidant activity of dark-colored vegetables and fruits revealed that they could be used in promoting a healthy diet based on consumption of 5 vegetables and fruits a day follow the so-called “the principle of rainbow” as recommended by NRC and ACS.

Chinese Boneless Painting skill is said that it has been applied since Liang of the Southern dynasties (502-557) , quite early in Chinese history. Compared to the Chinese Fine-Brushwork Painting, the Chinese Boneless Painting puts more emphasis on free strokes and impression rather than reality and details. Chinese Boneless Painting skill was applied to a variety of subjects. In this thesis, we focus on synthesizing fruits and vegetables. Our proposed system consists of two major parts: stroke generation and colorization. Input a photo of fruits or vegetables. We analyze silhouettes of objects in the input image to generate streamlines. Then we apply the brush model to the streamlines for color strokes and contour strokes. After mapping colors from input image to traditional Chinese ink-painting colors, we can generate the Chinese Boneless Painting style easily without any painting skill.
