“…Spinach (Spinacia oleracea L.) is an economically important green leafy vegetable with useful nutritional content (Ball, 2006), therefore obtaining a superior genotype of this crop is particularly profitable. For this purpose, it was necessary to explore the diversity of spinach cultivars and choose the best genotype among them.…”

Spinacia oleracea L. is an edible crop and considered as super food due to high nutrient values. Due to these properties the pot-based project was designed to explore the most diverse accession of this species, 31 local S. oleracea accessions were evaluated taxonomically on the basis of morphological and anatomical markers. Seeds were sown in clay pots to evaluate different morphological characters. The germination period varied from 6 to 15 days while variation in number of leaves was observed to be from 12 to 68 leaves per plant. Moreover, abaxial and adaxial epidermal leaf analysis was examined under light microscope to study the existing anatomical variations. Substantial variations were observed among quantitative characters including number of subsidiary cells (3-5 on both abaxial and adaxial sides), stomata number per unit area (6-21 on abaxial side; 8-18 on adaxial side) and stomatal index (13.9-28.6 on abaxial side; 14.8-25.5 on adaxial side). The shape of epidermal cells varied from tetragonal to pentagonal, hexagonal and irregular. The results concluded that leaf epidermal anatomical markers could be applied considerably in delimiting the species to solve the existing taxonomic problems among them. However, for more authentic results it would be preferred to use more taxonomic tools in integration with anatomy to study intraspecific variations.

“…Thiamin is relatively unaffected by light and stable to oxidation, but it is among the least stable vitamins in solutions at neutral pH such as milk (12,13). Riboflavin is a heat stable vitamin, but it is very sensitive to oxidation and mainly to degradation by light (13)(14)(15). Its oxidation causes not only a loss in the nutritive value of dairy products but off-flavors, too (13,14).…”

The effect of manothermosonication (MTS), an emergent technology for food preservation, on thiamin, riboflavin, carotenoids, and ascorbic acid was evaluated in milk and orange juice. The effect of both heat treatment and MTS on several compounds produced in nonenzymatic browning in model systems was also studied. MTS does not affect significantly the nutrient content studied. However, it changes the behavior of nonenzymatic browning. No formation of 5-(hydroxymethyl)-2-furfuraldehyde (HMF) was detected in fruit juice model systems after heat and MTS treatments at the experimental conditions used. In a milk-resembling system, free HMF formation by MTS is higher compared to that by heat treatment. As the MTS temperature increases, free HMF production by both treatments equaled on another. For bound HMF the production rate is lower by MTS than by heat treatment under the experimental conditions used. Formation kinetics of brown pigments and that of fluorescent compounds are different for both treatments. Fluorescence and brown pigment production are faster in MTS.

Beef is a good source of several vitamins and minerals but data on the net contribution to the human diet is lacking. The objective was to quantify the net nutrient contribution of the beef supply chain to provide vitamins and minerals to the human diet. Beef cattle production parameters for the beef supply chain were as described by Baber et al., 2018 with the red and organ meat yield from each production segment estimated using literature values of serially-harvested beef cattle. Nutrient concentration of feeds was acquired from feed composition tables in nutrient requirement texts, and the nutrient concentration of beef and organ meats was based on 2018 USDA Food and Nutrient Database for Dietary Studies. The nutrient absorption coefficients of feeds, red meat, and organs were acquired from the literature. The human-edible conversion ratio was >1.0 for phosphorus when only red meat yield was considered indicating that the beef supply chain produced more human-edible phosphorus than it consumed. When organ meats were included, riboflavin, niacin, choline, and phosphorus had conversion ratios >1.0. After adjusting for the absorption of nutrients, the beef supply chain was a net contributor of niacin and phosphorus in the human diet when accounting for red meat yield only, but when including organ meats, iron, riboflavin, and choline also had conversion ratios >1.0. The maximum proportion of corn in the corn grain plus distillers’ grains component of the feedlot diets for the absorbable conversion ratio to be ≥1 ranged from 8.34 to 100.00% when only red meat yield was considered and from 32.02 to 100.00% when red and organ meats were considered. In conclusion, the current beef production system in the Southern Great Plains produces more human-absorbable iron, phosphorus, riboflavin, niacin, and choline to the human diet than is consumed in the beef supply chain.
