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.


Package and Storage:

25kg/Carton or according to the reuqests of the customers.
