Consumers have been increasingly seeking healthier foods without sacrificing sensory satisfaction and convenience, which are highly acclaimed attributes in modern times. Minimally processed products can meet these demands. The present study evaluated the microbiological, microscopic and physicochemical quality of minimally processed fruits and vegetables marketed in Cuiabá, Brazil. A total of 36 samples, consisting of sliced melon, fruit salad in pieces, grated carrot, diced melon, sliced papaya and pineapple rounds were subjected to microbiological, microscopic and physicochemical analyses. <em>Salmonella</em> spp. was absent in all samples, while 27.8% (10/36) of the samples showed coliform counts at 45 °C over 2.0 and 2.7 log CFU.g<sup>-1</sup> in fruit and vegetables, respectively. Light dirt and foreign matter were present in 55.5% of the samples (20/36), including wood fragments and insect/animal excrements (rat hair) in 13.9% (5/36) of the samples. The pH and soluble solids (°Brix) results ranged from 3.84 to 6.66 and from 8.19 to 10.24, respectively. The products were in different stages of maturation and 27.8% (10/36) of the sliced papaya and grated carrots were in unsatisfactory sanitary conditions under the current Brazilian legislation.

Reported Data

Abstract Objectives To assess the overall nutritional quality of meals chosen by undergraduate students during weekday lunches at campus all-you-care-to-eat dining halls. Methods A previously validated exit survey was used to collect self-reported data from undergraduate students on foods and beverages they consumed during a single visit to two all-you-care-to-eat dining halls on the George Mason University Fairfax campus, during 4 weeks. (n = 468) Nutritional quality of each meal was evaluated on a 7-point rubric, according to the ‘Wellness Meal’ standards from the Partnership for a Healthier America: ≤700 kilocalories, ≤10% calories from saturated fat, ≤800 mg sodium, ≥2 ounces whole grains, ≥1 cup lowfat dairy, ≥ 1.75 cups fruits and vegetables, and ≥ 2 ounces lean protein. Results Of the maximum score of 7 on the meal nutritional quality rubric, 4 participants earned the highest score of 5, whereas 43, 150, 132, 88, and 51 participants had scores of 4, 3, 2, 1, and 0, respectively. The most commonly attained rubric standard was saturated fat, where 60% of participants consumed ≤ 10% calories from saturated fat and average consumption was 9.1% (± 5.4%) of calories. The least achieved rubric category was lowfat dairy, where only 2% of students consumed 1 cup equivalent, followed by only 9% of participants having consumed the 2 ounce equivalent of whole grains. Approximately one-third of students met calorie, lean protein, sodium, and fruit/vegetable standards. Conclusions Despite a wide variety of food options in the campus all-you-care-to-eat dining halls during the lunch hours, most undergraduate students consumed meals of subpar nutritional quality, with the vast majority meeting fewer than half the categories on the meal nutritional quality rubric. All-you-care-to-eat university dining halls may be a prime location for nutrition education and interventions.

AbstractObjectivesTo assess the nutritional quality of food aid delivered by food banks in France and to identify practical modifications to improve it.DesignNational-level data were collected for all food aid distributed by French food banks in 2004, and its nutrient content per 2000 kcal was estimated and compared with French recommendations for adults. Starting with the actual donation and allowing new foods into the food aid donation, linear programming was used to identify the minimum changes required in the actual donation to achieve the French recommendations.ResultsFrench food-bank-delivered food aid does not achieve the French recommendations for dietary fibre, ascorbic acid, vitamin D, folate, magnesium, docosahexaenoic acid, α-linolenic acid and the percentage of energy from saturated fatty acids. Linear programming analysis showed that these recommendations are achievable if more fruits, vegetables, legumes and fish were collected and less cheese, refined cereals and foods rich in fat, sugar and/or salt. In addition, new foods not previously collected are needed, particularly nuts, wholemeal bread and rapeseed oil. These changes increased the total edible weight (42%) and economic value (55%) of the food aid donation, with one-third of its edible weight coming from fruits and vegetables, one-third from staples, one-quarter from dairy products and approximately a tenth from meat/fish/eggs.ConclusionsImportant changes in the types and amounts of food collected will improve the nutritional quality of food-bank-delivered food aid in France. Such changes are recommended to improve the diets of deprived French populations.

Minimally Processed Vegetables

The increasing demand for fresh fruits and vegetables and for convenience foods is causing an expansion of the market share for minimally processed vegetables. Among the more common pathogenic microorganisms that can be transmitted to humans by these products are Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella. The aim of this study was to evaluate the microbial quality of a selection of minimally processed vegetables. A total of 181 samples of minimally processed leafy salads were collected from retailers in the city of Sao Paulo, Brazil. Counts of total coliforms, fecal coliforms, Enterobacteriaceae, psychrotrophic microorganisms, and Salmonella were conducted for 133 samples. L. monocytogenes was assessed in 181 samples using the BAX System and by plating the enrichment broth onto Palcam and Oxford agars. Suspected Listeria colonies were submitted to classical biochemical tests. Populations of psychrotrophic microorganisms &gt;106 CFU/g were found in 51% of the 133 samples, and Enterobacteriaceae populations between 105 and 106 CFU/g were found in 42% of the samples. Fecal coliform concentrations higher than 102 CFU/g (Brazilian standard) were found in 97 (73%) of the samples, and Salmonella was detected in 4 (3%) of the samples. Two of the Salmonella-positive samples had &lt;102 CFU/g concentrations of fecal coliforms. L. monocytogenes was detected in only 1 (0.6%) of the 181 samples examined. This positive sample was simultaneously detected by both methods. The other Listeria species identified by plating were L. welshimeri (one sample of curly lettuce) and L. innocua (2 samples of watercress). The results indicate that minimally processed vegetables had poor microbiological quality, and these products could be a vehicle for pathogens such as Salmonella and L. monocytogenes.

And Storage

Present dietary recommendations for fruits and vegetables should be based on the bioavailability of essential nutrients at the time of optimum harvest. Few people, however, are fortunate enough to have available freshly harvested produce all year. With the development of improved postharvest technology, shelf life has increased dramatically in many parts of the world. How does the nutritional quality of fruits and vegetables change with increasing storage time, changes in storage atmosphere, different postharvest processes? Do these changes have an impact on dietary recommendations? Apples are capable of being stored for up to 12 months with properly managed temperature and storage atmosphere. Because information regarding this subject is lacking for apple (and many other fruits and vegetables), perhaps a model can be developed based on work with other commodities to help us understand the nutritional changes associated with different postharvest treatments.
