Its chemical properties, physical aspects of nature, citric acid at room temperature is a colorless or white crystalline granule or crystalline powder, odorless, taste salty and cool, soluble in water, insoluble in alcohol, in the humid air deliquescence. Citric acid in two forms: anhydrate or monohydrate. When crystallized from hot water, citric acid anhydrate generated; crystalline monohydrate is generated in cold water. When heated to 78 ℃ monohydrate will not hydrate decomposition. At 15 ° C, citric acid can also be dissolved in ethanol.

The food industry, mainly for citric acid sour agents, solubilizing agents, buffers, antioxidants, deodorization deodorant, flavor enhancers, gelling agents, toners, inhibit bacteria, color, improved flavor, promote invertase, etc. effect;

In the construction industry, sodium citrate can be added to concrete as the retarder in order to improve the tensile, compressive and frost resistance of cement products;

Washed, the result of citrate has good solubility in water, for water, Ca2 +, Mg2 + and other metal ions has excellent chelating ability, is also often used to produce non-phosphorus detergent;

Buildings, citric acid also has its place, as the retarder added to concrete in order to improve the tensile, compressive and frost resistance of cement products;

Energy-saving environmental protection, citric acid - sodium citrate buffer for flue gas desulfurization;

In addition, in the ceramic industry, sodium citrate can be used as grinding additive;

Citric acid as an important organic acid, citric acid produced worldwide in 2004 alone, about 1.4 million tons in recent years, citric acid supply sources gradually eastward, leading supplier disorder, prices declined. For now, good citric acid market, domestic and foreign demand for citric acid is gradually expanding, companies are reasonable offer, according to the network information is understood, investors citric acid or slightly rise.
