Ethyl Cellulose Coated Ascorbic Acid 97%

Briefing:
L-ascorbic acid is water soluble, highly sensitive to light and heat and easily oxidized into an inactive form diketogulonic acid. Some metal ions, such as copper, cobalt, Manganese, Zinc, Iron and organo-metallic compounds can speed up the oxidation and decomposition process of the material. A new kind of ascorbic acid derivative Coated Ascorbic Acid 97 is formed after coating with ethyl cellulose or other similar material in Vitamin C. It is both time and heat stable to ensure its availability for a longer period when it is properly stored in a cool dry place.

Coated Ascorbic Acid 97 is provided with such advantages as water-insoluble, good coating property and free-flowing ability, high percentage of coating rate, prolonged shelf life when mixed with other materials. It is widely used in pharmaceutical and food processing industry in the international market and achieved good effects.
