Vitamin from Other Supplements Vitamin C White Powder 99.0% Min Purity
Vitamin C, another name Ascorbic Acid, is a kind of acidic polyol with 6 carbon atoms. Its formula is C6H8O6 and molecular weight is 176.1. Ascorbic Acid is well-known for its antioxygenation. Most people are familiar with L-Ascorbic also called Vitamin C. Ascorbic acid is easy to be oxydated, but it can prevent different cells from damaging. So it is called antioxidant. Vitamin C participates the complex Metabolic process of the body. It can promote the growth and enhance the resistance of disease. When animals lack of Vitamin C, some symptoms like loss of appetite, growth retardation, anemia etc. will appear.

Recommendation On Use
Vitamin C can be used in wheat flour and its maximum usage is 0.2g/kg.
It also can be used in Concentrated fruit and vegetable juice and the usage should be according the requiremens of the production.
Vitamin C is used in fruit juice and carbonate beverages for prevent from going oxidative deterioration. Theoretically every 3.3mg Vitamin C can react with 1ml air. If the average assay of the air in the bottom clearance of the container is 5ml, 15-16g Vitamin C will make the oxygen assay in air be lower than critical level. And then prevent the products from discoloring and off-odor. Citric Acid can be used as synergist when Vitamin C was used as antioxidant.
