Potatoes are a good source of various nutritional and health promoting compounds such as Vitamin C, dietary fibers, potassium, magnesium, and carbohydrates. One of its fried products “potato chips” is the most popular snacks among consumers of all ages. This study presents useful data on total fats, reducing sugars, Vitamin C, minerals, total phenolics, antioxidant activity, glycoalkaloids, and acrylamide levels of potato chips made from three potato cultivars (Snowden, Lamoka, and Atlantic) grown at different locations in the USA. From the results obtained, these potato chips are notable for their high content of vitamin C (min, 6.54 - max, 29.79 mg/100g), K (min, 1.10 - max, 1.65 %), and dietary fibers (2.14 to 3.71 %). The average levels of acrylamide were 902.02 µg/kg with a range 866.96 - 948.7 in continuous frying chips and 873.369 µg/kg in kettle cooked chips with the range 840.06 - 932.76. Kettle cooked potato chips retained a higher amount of nutrients and lower level of fats.

Basil (Ocimum basilicum L.) is one of the most popular plants cultivated worldwide. It is a good source of natural antioxidants and contains significant amounts of important phytochemicals. Thus, this study aimed to evaluate the macronutrients, minerals, vitamins and bioactive compounds of fresh and dehydrated basil and its hot and cold infusions. The basil presented high moisture (94.12%) and low lipid (0.20%), carbohydrates (5.25%) and dietary fibers (2.33%) content. There was no difference in vitamin C concentrations, total phenolics and antioxidant capacity between fresh and dehydrated basil and between the hot and cold infusions (p > 0.05). Potassium and calcium were the most prevalent minerals in dehydrated basil. The consumption of basil, especially in dehydrated form, can contribute significantly to the daily intake of minerals, vitamins C and E, and infusions are not a relevant choice of consumption to achieve nutritional recommendations.

AbstractChinese kale (Brassica oleracea var. alboglabra) has high nutritional value. This study investigated the contents of glucosinolates, antioxidants (chlorophylls, carotenoids, vitamin C, and total phenolics), and antioxidant capacity in five organs from six varieties of Chinese kale. The highest concentrations of individual and total glucosinolates were in the roots and inflorescences, respectively. The highest levels of antioxidants and antioxidant capacity were in inflorescences and leaves. Plant organs played a predominant role in glucosinolate and antioxidant accumulation. Glucoiberin, glucoraphanin, and glucobrassicin, the main anticarcinogenic glucosinolates, could be enhanced simultaneously because of their high positive correlations. The relationship between glucosinolates and antioxidant capacity indicated that glucobrassicin might contribute to the total antioxidant capacity. These results provide useful information related to consumption, breeding of functional varieties, and use of the non-edible organs of Chinese kale.

AbstractInterest in the biochemical composition of Viburnum opulus fruit has intensified due to the food industry’s demand for natural vitamins, pigments and other substances that enhance the value of different foods. The present study was conducted to determine the agro-biological and biochemical variability of V. opulus and to select the genotypes that could best serve as sources of health promoting substances. Twelve selected genotypes were evaluated. ‘Leningradskaya Otbornaya’, V. opulus var. americanum, ‘Zarnitsa’, and local clone P2 were determined to be the best genotypes for growth in commercial plantations. Fruits of the local clone P3 were characterised by large amounts of total phenolics, ascorbic acid, and reducing sugars. V. opulus var. sargentii and V. opulus var. americanum contained exceptionally large amounts of total phenolics, 1460.0 and 1400.0 mg/100 g, respectively. The amount of ascorbic acid varied from 12.4 to 41.4 mg/100 g, the amount of carotenoids varied from 1.4 to 2.8 mg/100 g, the amount of anthocyanins varied from 23.2 to 44.6 mg/100 g, and the amount of total phenolics varied from 753.0 to 1460.0 mg/100 g. The presence of these large amounts of biologically active compounds enables their use as potent antioxidants. The data describing agro-biological characteristics, biochemical components, and health promoting activities of V. opulus fruits will increase the understanding of this plant and facilitate its use in the food and pharmaceuticals industry.

Moringa Oleifera Lam

Moringa oleifera Lam., commonly found tree in sub-Himalayan tracts of India, Pakistan, Bangladesh and Afghanistan has a high nutrition value. The leaves, flowers and immature pods of Moringa are used as a vegetable in many countries. The leaves are highly nutritious and medicinal in nature. They are a rich source of iron, calcium, vitamin A, vitamin C, proteins, and essential amino acids. Hence Moringa leaves can be a good source of protein for the vegetarians and the under-nourished population. Present investigation deals with the study of monthly variation in the nutritional value of Moringa leaves from the month of June 2015 to January 2016. Impact of urban sewage pollution and roadside vehicular pollution on the amount of reducing and total sugars, chlorophylls (a, b and total), proteins, vitamin-C and pH of the leaves, was also studied. Results revealed that the highest amounts of reducing sugars, total sugars, chlorophyll b and total chlorophyll during October 2015 whereas proteins, chlorophyll a, vitamin C and pH were highest during January 2016. Leaf samples collected from all the study sites exhibited minimum amounts of reducing sugars, chlorophylls (a, b and total) and pH during July 2015 whereas total sugars were lowest during December 2015. Proteins and vitamin C values were lowest during August and June 2015 respectively. Sewage and vehicular pollution showed an adverse effect on the nutritional contents of Moringa oleifera leaves. Of the two polluted sites, samples from near the sewage flow showed higher impact.

Size And Morphology

Plant-derived exosome-like nanovesicles (EPDENs) have recently been isolated and evaluated as potential bioactive nutraceutical biomolecules. It has been hypothesized that EPDENs may exert their activity on mammalian cells through their specific cargo. In this study, we isolated and purified EPDENs from the strawberry juice of Fragaria x ananassa (cv. Romina), a new cultivar characterized by a high content of anthocyanins, folic acid, flavonols, and vitamin C and an elevated antioxidant capacity. Fragaria-derived EPDENs were purified by a series of centrifugation and filtration steps. EPDENs showed size and morphology similar to mammalian extracellular nanovesicles. The internalization of Fragaria-derived EPDENs by human mesenchymal stromal cells (MSCs) did not negatively affect their viability, and the pretreatment of MSCs with Fragaria-derived EPDENs prevented oxidative stress in a dose-dependent manner. This is possibly due to the presence of vitamin C inside the nanovesicle membrane. The analysis of EPDEN cargo also revealed the presence of small RNAs and miRNAs. These findings suggest that Fragaria-derived EPDENs may be considered nanoshuttles contained in food, with potential health-promoting activity.

Acrylamide, a toxic compound and possible carcinogen is formed in high heated starchy foods like potatoes through the process of the Maillard reaction in which reducing sugars and the amino acid asparagine play a major role. Various strategies which are described in this paper have been employed to reduce the formation of acrylamide in potato chips. Among these tuber genetics, harvesting time, storage conditions frying temperatures and time, soaking and use of various additives seem to be effective tools for the industry as well as for consumer food preparation. The results of various studies will help the industry to adopt practical effective and innovative ways to reduce the levels of acrylamide even further and calm the markets from demanding to provide warning labels and the manufactures to pay penalties and higher costs
