Citric Acid is white powder or tiny crystals, indorous and salty, easily soluble in water, insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposd to moist air. It is used for food loosen agent, acidity modifier, or used in feedstuff, drug, medicine, film, tannage, fiber and rubber, or used as detergent and fire fight.
Citric acid can exist as anhydrous or monohydrous. The crystal form of citric acid is different due to different crystallization conditions, slightly weathered in dry air, hygroscopic in humid air, heating can be decomposed into a variety of products, and can react with acids, bases, glycerin, etc. Anhydrous citric acid is crystallized from hot water, while citric acid monohydrate is crystallized from cold water.

Citric acid is the organic acid with the largest yield produced by biochemical methods in the world. Citric acid and salts are one of the pillar products of fermentation industry, mainly used in the food industry.
In terms of food additives, it is mainly used in carbonated drinks, juice drinks, lactic acid drinks and other cool drinks and pickled products, and its demand is changed by the change of seasonal climate. Citric acid accounts for about 2/3 of the total consumption of sour agents. Adding citric acid to canned fruit can maintain or improve the flavor of the fruit, increase the acidity of certain fruits with low acidity when canning (reducing pH), weaken the heat resistance of microorganisms and inhibit their growth, and prevent the bacterial swelling and destruction that often occurs in canned fruits with low acidity.
Citric acid is an organic acid produced by microbial fermentation, which is widely used in the production of detergent, and its own specificity and chelation play an active role. Citric acid in the actual use of the process, has a good performance, mainly in terms of safety is more prominent, the preparation of citric acid raw materials are derived from food, which is safe food grade microorganisms.
