Surface films of vitamin E concentrates

Preparation and Properties of Vitamin E Concentrates*

Various observations necessarily made on vitamin E concentrates in connection with work on purification of vitamins (l), while outside the scope of that paper, disclosed many pitfalls which the experimenter may avoid with the information here presented. If certain simple precautions are not taken during extraction and saponification of the wheat germ oil, losses of over 90 per cent of its vitam...

Incorporation of vitamin E in poly(3hydroxybutyrate)/Bioglass composite films: effect on surface properties and cell attachment.

This study investigated the possibility of incorporating alpha-tocopherol (vitamin E) into poly(3hydroxybutyrate) (P(3HB))/Bioglass composites, which are being developed for bone tissue engineering matrices. P(3HB) films with 20 wt% Bioglass and 10 wt% vitamin E were prepared using the solvent casting technique. Addition of vitamin E significantly improved the hydrophilicity of the composites a...

Vitamin E Improves Morphology and Absorptive Surface of Small Intestine in Broiler Chickens Reared at High Altitude

Under high altitude conditions, the effects of vitamin E (α-tocopherol) on growth performance, intestinal morphology (villus size and type), and absorptive surface area of broiler chickens were evaluated. Chickens were fed diets supplemented with 0, 100, 200 or 400 IU/kg vitamin E for 42 days. On days 14, 28 and 42, birds were sacrificed and three segments of small intestine were dissected. The...

Study Of Interaction of Glutathione, Vitamin C and Vitamin E Under Hyperbaric Oxygen

In order to study the interaction of glutathione, vitamin C and vitamin E under hyperoxia (95 % oxygen) and hyperbaric oxygen (2.5 atmospheric pressure), 20 days old male Guinea pigs were fed with basal vitamin C free diet, while receiving a vitamin C supplement of either high concentration (50 mg/day) or low concentration (1 mg/day) for two weeks. Animals were than exposed to hyperoxia and hyp...
