Short Description:

In the food and beverage industry as sour agent, flavoring agent and preservative, preservation

Agent; It is used as an antioxidant in the chemical industry, cosmetic industry and washing industry

, plasticizer, detergent, etc.

Product Paramete

Application

Natural citric acid is widely distributed in nature. Natural citric acid is found in plants such as lemon, citrus, pineapple and other fruits and animal bones, muscles, and blood. Synthetic citric acid is produced by fermentation of sugar-containing substances such as sugar, molasses, starch, and grapes. .

Application area

In terms of food additives, it is mainly used in carbonated drinks, fruit drinks, lactic acid drinks and other cool drinks and pickled products, and its demand is changed by seasonal climate changes. Citric acid accounts for about 2/3 of the total consumption of sour agents. Adding citric acid in canned fruit can maintain or improve the flavor of the fruit, increase the acidity of some fruits with low acidity (reduce the pH value), weaken the heat resistance of microorganisms and inhibit their growth, and prevent the bacterial swelling and destruction of fruit with low acidity. Adding citric acid to candy as a souring agent is easy to harmonize with the fruit. The use of citric acid in the gel food if sauce, jelly can effectively reduce the negative charge of pectin, so that the hydrogen bond between pectin molecules to gel. In the processing of canned vegetables, some vegetables are alkaline reaction, with citric acid as pH adjustor, not only can play a role in seasoning, but also can maintain its quality. Citric acid has the characteristics of chelation and pH adjustment, which can increase the performance of antioxidant, inhibit enzyme activity and prolong the shelf life of food in the processing of quick-frozen food.

Citric acid is an organic acid produced by microbial fermentation. It is widely used in the production of detergent, and its specificity and chelation play a positive role.

Citric acid is a kind of fruit acid, the main role is to speed up the renewal of the cuticle, often used in lotion, cream, shampoo, whitening products, anti-aging products, acne products, etc. In chemical technology, citric acid can be used as chemical analysis reagent, as experimental reagent, chromatographic analysis reagent and biochemical reagent; Used as a complexing agent, masking agent.

The addition of citric acid to compound feed can be sterilized, prevent mildew, and prevent Salmonella and other infections of animal feed. Citric acid intake by animals can reduce the proliferation of pathogens and inhibit the production of toxic metabolites, and improve the stress of animals.
