Ascorbic acid, a water-soluble dietary supplement, is consumed by humans more than any other supplement. On exposure to light, it gradually darkens. In the dry state, it is reasonably stable in air, but in solution it rapidly oxidizes. L-Ascorbic acid is a naturally occurring electron donor and therefore serves as a reducing agent. It is synthesized from glucose in the liver of most mammalian species, excluding humans, non-human primates, or guinea pigs who must obtain it through dietary consumption. In humans, L-Ascorbic acid acts as an electron donor for eight different enzymes, including those related to collagen hydroxylation, carnitine synthesis (which aids in the generation of adenosine triphosphate), norepinephrine synthesis, tyrosine metabolism, and amidating peptides. L-Ascorbic acid demonstrates antioxidant activity that may be of some benefit for reducing the risk of developing chronic diseases such as cancer, cardiovascular disease, and cataracts.Promote the biosynthesis of bone collagen, which is conducive to faster healing of tissue wounds; .Promote the metabolism of tyrosine and tryptophan in amino acids, and prolong the life span of the body; .Improve the utilization of iron, calcium and folic acid, and improve the metabolism of fat and lipids, especially cholesterol; .Promote the growth of teeth and bones, prevent bleeding of the gums, and prevent joint and waist pain; .Enhance the anti stress ability and immunity of the body to the external environment; .Powerful antioxidant support for protection against harmful free radicals. Vitamin C also acts as a collagen biosynthesis regulator. It is known to control intercellular colloidal substances such as collagen, and when formulated into the proper vehicles, can have a skin-lightening effect. Vitamin C is said to be able to help the body fortify against infectious conditions by strengthening the immune system. There is some evidence (although debated) that vitamin C can pass through the layers of the skin and promote healing in tissue damaged by burns or injury. It is found, therefore, in burn ointments and creams used for abrasions. Vitamin C is also popular in anti-aging products. Current studies indicate possible anti-inflammatory properties as well.1.Applied in Food Field As a substitute for sugar, it can prevent fat. It is mainly used in kinds of beverage, fat and grease, frozen food, processing vegetables, jelly, jam, soft drinks, chewing gum, toothpaste and mouths tablets. 2.Applied in Cosmetic Field Delaying aging. Protects collagen, improves skin elasticity and luster, whitens, moisturizes and removes wrinkles, reduces wrinkles and keep skin smooth and smooth. 3.Applied in Feed field Used as nutritional element in feed additives. We have different ascorbic acid sizes,they are as follows: Ascorbic Acid Granulation 90%, Ascorbic Acid Granulation 97%,Coated Ascorbic Acid, Ascorbic acid fine powder 100 mesh and so on. Coated ascorbic acid is often used as food or feed additives. The assay is 97%.
