Naturally Present Water Soluble White Vitamin C Crystal Powder For Metabolism


 

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. The appearance of Vitamin C is white crystal with faintly acid. Vitamin C is made by Glucose through the process of hydrogenation and oxidized. It is the most important soluble vitamin in the body of human beings. Most of the mammals can compound vitamin C in their body. But human beings can not do that and must beobtained from diet or supplementation. Ascorbic Acid is well-known for its antioxygenation. Most people are familiar with L-Ascorbic Acid also called Vitamin C. When it is not vitamin format, ascorbic acid was often used for film production. Ascorbic acid is easy to be oxydated, but it can prevent different cells from damaging. So it is called antioxidant. It must be stored in cold and dark place. Because it can oxidate the touched metals, it can not be stored in metal vessels.

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.
