Storage method

Stored sealed and protected from light.

Synthesis method

Add sodium bicarbonate and isopropyl alcohol to the ascorbic acid solution successively, and obtain it through the reaction. It can also be obtained by heating the reaction between ascorbic acid and sodium carbonate and filtering it.

Purpose

1. Antioxidants in meat and other foods.

2.As a food nutritional fortifier, it can also be used as a color protectant and antioxidant. It has the same effect as ascorbic acid.
