Supplements Vitamin C Raw Materials Powder Beneficial as A cure for Diabetes
Vitamin C is a white crystal or crystalline powder. Its melting point is 190℃～192℃, no odour and sour taste. It is easily dissoved in water, slightly dissovled in ethanol and not dissovled in chloroform and diethyl ether. Vitamin C is a kind of soluble vitamin and has very strong reducibility. It is easy to break down when heat or in the solution. And it is easier to be oxidized in alkaline conditions. Vitamin C in food is absorbed by the upside of small intestine. Once absorbed, it will spread in to the soluble stuctures of the body.

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.
25kg/carton or according to the requests of the customers.
Store in a tightly closed container and a cool, dry place under an inert atmosphere. Do not store in direct sunlight.
