Both citric acid monohydrate and citric acid anhydrous can be used in food. There is no danger in proper packaging and use. Citric acid monohydrate is more suitable as a food additive.

The specific differences between the two are as follows:

1. Different properties:

Anhydrous citric acid is colorless and translucent crystals or white particles or white Crystalline powder, odorless, extremely sour taste, soluble in water, alcohol and ether. Anhydrous citric acid can be obtained by controlling the appropriate temperature during crystallization.

Citric acid monohydrate is mainly used in the food and beverage industry as a sour agent, flavoring agent, preservative, and preservative. It is also used as antioxidant, plasticizer and detergent in the chemical industry, cosmetics industry and washing industry.

2. Different uses:

Anhydrous citric acid is mainly used in the food and beverage industry as a sour agent, acidity regulator, flavoring agent, preservative, and preservative. It is also used as antioxidant, plasticizer and detergent in the chemical industry, cosmetics industry and washing industry.

Citric acid monohydrate is mainly used in the food and beverage industry as a sour agent, flavoring agent, preservative, and preservative. It is also used as antioxidant, plasticizer and detergent in the chemical industry, cosmetics industry and washing industry.

3. Different molecular formulas:

The molecular formula of citric acid anhydrous is C6H8O7

The molecular formula of citric acid monohydrate is C6H8O7·H2O

Note:

Health hazards

Irritant. In industrial use, contact may cause eczema.

Explosion hazard

This product is flammable and irritating.

Hazardous Characteristics

Powder and air can form explosive mixtures. In case of open flame, high heat or contact with oxidants, there is a risk of combustion and explosion. Citric acid monohydrate and sodium citrate dihydrate are mixed with citrate buffer solution of pH 6.0.

Since the pH is 6, the buffer pair is disodium salt and trisodium salt (citric acid Ka1=7.4×10^-4, Ka2=1.7×10^-5, Ka3=4.0×10^- 7).
