It is the most important soluble vitamin in the body of human beings. Most of the mammals can compound vitamin C in their 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.

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.
