Description Occurs widely in animals and plants. Good sources are citrus fruits and hip berries. Isolated from ox adrenal cortex, lemons and paprika. Production industrially on a large scale from glucose. Vitamin (antiscorbutic), antioxidant, nutrient, preservative consistency enhancer. It is used to reduce discoloration, mainly browning caused by polyphenol oxidase, in fruit and vegetable products. It is used to enhance colour formn. and to reduced the formn. of nitrosamines in meat products. It is used synergistically with Sulfur dioxide <ht>HVF10-P</ht> in wine and beer as a perservative. Assists formn. of the gluten network in bread making, thus enhancing bread volume. L-Ascorbic acid is found in many foods, some of which are cabbage, hyssop, ginseng, and pancake.
