    Vitamin C is white and slightly yellow crystalline powder with no odour. It is easily dissolved in water and the solubility at 20℃ is 33g/100g. It can not be dissovled in vegetable oil, slightly dissoved in ethanol (solubility is only 2g/100g). The color of Vitamin C will get darker when being light and it is stable in the dry conditions. Heat and light can destroy easily the solution of Vitamin C, especially in the alkaline condition and in the presence of metal. So it should pay more attention to avoid metals and air touch in water and containers.

    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.
