sodium erythorbate is a water-soluble antioxidant, which is an important antioxidant in the food industry. Its antioxidant performance is better than that of vitamin C, and the price is cheap, and without any side effects. In the food industry, it is mainly used for meat products, fruits, vegetables, cans, jam, beer, soda, fruit tea, fruit juice, wine and so on. China provides for all kinds of canned, jam and frozen fish, the maximum use of 1.Og/kg; Can also be used for meat products, the maximum use of 0. 5g/kg (ascorbic acid); Can also be used for wine and fruit juice drinks, the maximum use of 0. 15g/kg; Can also be used for beer, the maximum use of 0. 04g/kg.
