Effects of amaranth addition on the pro‐vitamin A content, and physical and antioxidant properties of extruded pro‐vitamin A‐biofortified maize snacks

Journal of the Science of Food and Agriculture, 2015
AbstractBACKGROUNDPro‐vitamin A‐biofortified maize snacks with added leafy vegetable may have a potential as nutritious and health‐promoting products, especially in addressing vitamin A deficiency, which is prevalent in developing regions. The objective of the study was to determine the effects of adding amaranth leaf powder on the physical ...

Bioaccessibility of Pro-Vitamin A Carotenoids Is Minimally Affected by Non Pro-Vitamin A Xanthophylls in Maize (Zea mays sp.)

Journal of Agricultural and Food Chemistry, 2008
The absorption of some carotenoids has been reported to be decreased by coingestion of relatively high concentrations of other carotenoids. It is unclear if such interactions occur among carotenoids during the digestion of plant foods. Current varieties of maize contain limited amounts of the pro-vitamin A (pro-VA) carotenoids beta-carotene (BC) and ...

Non-Pro-Vitamin A and Pro-Vitamin A Carotenoids in Atopy Development

International Archives of Allergy and Immunology, 2013
Carotenoids are important derivatives of the human diet and occur in high concentrations in the human organism. Various carotenoids are also present in human breast milk and are transferred to breast-fed children. The alternative to breastfeeding is supplementation with an infant milk formula, but these formulas contain only a limited variety of ...

The Bioavailability of (pro) Vitamin A Carotenoids and Maximizing the Contribution of Homestead Food Production to Combating Vitamin A Deficiency

International Journal for Vitamin and Nutrition Research, 2007
An estimated 100–140 million children worldwide suffer vitamin A deficiency disorders (VADD). Strategies for combating VADD are best used in combination because they serve particular target groups and none has full coverage. Homestead food production (HFP) can contribute to combating vitamin A deficiency directly, by increasing intake of vitamin A ...

Improving the nutritional value of Golden Rice through increased pro-vitamin A content

Nature Biotechnology, 2005
"Golden Rice" is a variety of rice engineered to produce beta-carotene (pro-vitamin A) to help combat vitamin A deficiency, and it has been predicted that its contribution to alleviating vitamin A deficiency would be substantially improved through even higher beta-carotene content. We hypothesized that the daffodil gene encoding phytoene synthase (psy),

Facile and selective metalation of 7-dehydro-cholesterol (pro-vitamin D3)

Tetrahedron Letters, 1984
Abstract Subsequent treatment of 7-dehydrocholesterol with trimethylsilylmethylpotassium in tetrahydrofuran, dry ice, mineral acid and diazomethane gives a regioisomerically pure, homoconjugated ester as a diastereomeric mixture, the minor component of which turns out to be thermodynamically more stable than a conjugated isomer.
