Food grade citric acid High quality
Product Description
It is mainly used in the food and beverage industry as a sour agent, flavoring agent, preservative and preservative. It is also used as an antioxidant, plasticizer and detergent in the chemical industry, cosmetic industry and washing industry.
citric acid has obvious retarding effect when used in concrete, and the content of citric Acid in concrete is usually 0.01%~0.10%. When the content of concrete is 0.05%, the strength of concrete for 28 days is still improved, and the strength will be weakened if the content continues to increase. The air content of concrete was slightly changed by adding citric acid, and the frost resistance of concrete was also improved.
