Ascorbic acid, a water-soluble dietary supplement, is consumed by humans more than any other supplement. The name ascorbic means antiscurvy and denotes the ability of ascorbic to combat this disease. Vitamin C is the l-enantiomer of ascorbic acid. Ascorbic acid deficiency in humans results in the body's inability to synthesize collagen, which is the most abundant protein in vertebrates.
In the pharmarceutical industry:
It can be used of treat scurvy and various acute and chronic in fectious diseases, are applicable to the lack of VC.
In the food industry:
It can be used as both nutritional supplements and VC in food preservation, and is widely used in meat products, fermented flour products, beer, refreshments, fruit juice, canned fruit, canned meat, etc. It is also commonly used in cosmetics, feed additives and other industrial fields.
