APPLICATION AND USAGES
Vitamin C takes part in many metabolism procedures in the human body, helps decrease brittleness of blood capillaries and increase body resistance. In addition to prevention of scurvy, it is often used as a supplement for treatment of acute or chronic infection diseases or purpura.
Vitamin C is widely used in many fields such as food, beverage, breeding and forage additives. Its main functions are reflected in following six aspects:
1. Keep food, fruits and beverage fresh and prevent them from producing unpleasant smell.
2. Prevent formation of nitrous amine from nitrous acid in meat products.
3. Improve dough quality and make baked food expand to its maximum.
4. Compensate the Vitamin C losses of beverage, fruits and vegetables during processing procedures.
5. Used as a nutritional element in additive
6. Feed additives
