1, citric acid is mainly used as acidulant, solubilizer, buffer, antioxidant, deodorant, flavor enhancer, gelling agent, coloring agent and so on. In addition, citric acid also inhibit bacteria, color protection, improve flavor, promote the transformation of sucrose and other functions.

2, citric acid also has a chelating effect, can remove some harmful metals. Citric acid can prevent oxidation due to enzyme-catalyzed and metal-catalyzed, thus preventing frozen fruit discoloration and flavor.

3, in the food additives are mainly used in carbonated drinks, fruit juice drinks, lactic acid drinks and other refreshing drinks and pickled products, the demand for which is subject to seasonal climate changes and changes. Citric acid accounts for about 2/3 of the total consumption of acidulants.

4, add citric acid in canned fruits can maintain or improve the flavor of the curated fruits, improve the acidity of some of the lower acidity of the fruits canned, weaken the microbial resistance to heat and inhibit its growth, to prevent bacterial bloating and destruction of canned fruits often occurring in the lower acidity of the canned fruits.

Citric Acid in the Chemical and Textile Industry

Citric acid can be used in chemical technology as a reagent for chemical analysis, as a reagent for experimental reagents, chromatographic analysis reagents and biochemical reagents; used as a complexing agent, masking agent; used to formulate buffer solutions. The use of citric acid or citric acid salts as a detergent, can improve the performance of washing products;

Can quickly precipitate metal ions, to prevent pollutants from re-attachment to the fabric, to maintain the washing of the necessary alkalinity; so that dirt and ash dispersion and suspension; to improve the performance of the surfactant is an excellent chelating agent; can be used as a test of the construction of ceramic tiles of the acid resistance of the reagent.

The formaldehyde pollution of clothing has been a very sensitive issue, citric acid and modified citric acid can be made into a formaldehyde-free anti-wrinkle finishing agent for the anti-wrinkle finishing of cotton fabrics. Not only good anti-wrinkle effect, and low cost.
