Disodium hydrogen citrate, also known as disodium citrate, is an acid salt of citric acid, which can be used in food processing as an antioxidant and can also enhance the effect of other antioxidants. The substance can also be used as an acidity regulator and chelating agent. Common products include gelatin, jam, candy, carbonated beverages, wine, and processed cheese.
Nature:
1. It is a white crystalline powder, soluble in water and slightly soluble in alcohol.
2. It appears acidic in solution. It has a regulatory effect on acid-base balance.
Usage:
Sodium hydrogen citrate hydrate is mainly used as an acid-base balancing agent, commonly used to regulate the pH value of urine, and to treat diseases such as urinary tract infections and stones.
Method:
The preparation method of sodium hydrogen citrate hydrate is generally to react citric acid with sodium hydroxide to form a product, which is then crystallized.
Security information:
During use, it is important to control the dosage and avoid excessive intake.
