White Powdered Absorbable Vitamin C Antioxidant Easily Dissloved In Water
| Vitamin C (Ascorbic Acid) is a natural organic chemical with antioxygenation. Pure ascorbic acid is white solid but ascorbic acid with impurity is slight yellow. Ascorbic Acid is easy dissolved in water to be the slightly acidic solutoin. This material is named “L-hexuronic acids” at the biginning but when it was found that there was the activity of Vitamin C in the body of animals, it was renamed as ascorbic acid. Ascorbic Acid is derived from glucose and many animals can compound in their body but the human being can not. Human beings only get it from the fruits. |  |

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.
