Ascorbic acid powder, also known as vitamin C powder, is an acidic polyhydroxy compound containing 6 carbon atoms, which exists naturally in fresh fruits and vegetables. VC can exist in the body in either oxidized or reduced form, and plays an important role in the redox reaction process in the body.
It is widely used in the fields of medicine, food, cosmetics and feed.
China is the world's largest producer of vitamin C raw materials, with a production capacity of more than 300,000 tons. As a daily supplement, the demand for vitamin C has increased significantly. In addition to vitamin C raw materials (powdered), we can also customize vitamin C lozenges and chewable tablets. In addition, the vitamin C and derivatives supplied by our company are exported to many countries.
It is a water-soluble vitamin. VC powder is easily soluble in water, insoluble in fat solvents, stable in acidic environments, but unstable in oxygen, heat, light and alkaline environments, so it is best stored in a low temperature environment.
