Citric acid products are generally divided into food grade, industrial production grade, etc. according to their use and composition, but this is only the classification of its level, and the classification of citric acid is different. What is the main reason? What about the category?

The classification of citric acid should be based on the number of crystal water contained, such as: anhydrous, monohydrate, and dihydrate. Anhydrous lemons can be obtained when the water content is controlled at a suitable ambient temperature during crystallization. acid.

Citric acid, also known as citric acid, is a key organic acid in industrial chemistry. It has a wide range of uses in manufacturing industries such as industrial production, food industry, and cosmetics industry. However, depending on different water content categories, it is mainly used for different purposes.

Citric acid monohydrate is used as a sour agent, flavoring agent, preservative, and preservative in most food and beverage manufacturing industries. It is also used as an antioxidant, plasticizer, and detergent in the chemical industry, cosmetics industry and washing manufacturing industry; anhydrous citric acid does not contain any crystal water and is easily deliquescent in humid air. It is mainly used as a sour agent, acidity regulator, flavoring agent, preservative, and preservative in the food and beverage manufacturing industries.
