Product introduction:
Citric acid is an important organic acid, also known as citric acid. It is a colorless crystal and often contains one molecule of crystal water. It is odorless, has a strong acid taste, and is easily soluble in water. The calcium salt is easier to dissolve in cold water than in hot water. This property is often used to identify and separate citric acid. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization. It has many uses in industry, food industry, cosmetics industry, etc.
Description:
At room temperature, citric acid is colorless translucent crystals or white particles or white crystalline powder, odorless, very acidic, astringent, weakly corrosive, strong deliquescent, and accompanied by the formation of crystal water compounds. Slightly deliquescent in humid air. It can exist in the form of anhydrous or monohydrate: when citric acid crystallizes from hot water, it forms anhydrous; when it crystallizes in cold water, it forms a monohydrate.
Application:
1) Used as souring agent, flavoring agent, preservative and preservative in the food and beverage industry.
2) Used as antioxidant, plasticizer and detergent in chemical industry, cosmetic industry and washing industry.
