Sodium D-isoascorbate detection

The main uses of D-isoascorbate sodium include: it is an important antioxidant and preservative in the food industry, which can maintain the color and natural flavor of food, extend its shelf life, and have no toxic or side effects. In the food industry, it is mainly used for meat products, fruits, vegetables, canned goods, jam, beer, soda, fruit tea, juice, wine, etc. The purpose of the present invention is to provide a rapid detection method for the antioxidant D-isoascorbic acid sodium in food, in response to the defects in the existing technology mentioned above. In order to achieve the above objectives, the technical solution provided by the present invention is: a detection method for food antioxidant D-isoascorbate sodium, which involves acidification of 2mL of a sample solution with 0.5mL of 0. lmol/L HCl solution, adding a few drops of nitroferricyanide sodium test solution, and then adding 1mL of 0. lmol/L NaOH solution to observe the color. The beneficial effect of the present invention is that the detection method for food antioxidant D-isoascorbate sodium provided by the present invention has fast detection speed, high accuracy, and is suitable for detection in industrial large-scale production
