Product features
Citric acid exists in two forms: anhydrous and monohydrate. The difference between them is that anhydrous citric acid has no crystal water, while citric acid monohydrate contains one crystal water in the molecule. Citric acid has the properties of carboxylic acid and alcohol. Monovalent, divalent and trivalent salts and esters of citric acid can be obtained. Citric acid participates in the human body's metabolic process, improves energy metabolism, and is also a necessary substance for maintaining acid-base and ion balance in organisms. As a food additive, citric acid has low calories and is safe and harmless.
