usage

1. Used in chemical and textile industry

Citric acid in chemical technology can be used as chemical analysis reagents, as experimental reagents, chromatographic reagents and biochemical reagents;Used as complexing agent, masking agent;To prepare buffer solution.Can improve the performance of washing products, can quickly precipitate metal ions, prevent contaminants re attached to the fabric, maintain the essential alkaline washing.

2. Used in the food industry

Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, soda, wine, candy, snacks, biscuits, canned fruit juice, dairy products and other foods.In all the market for organic acids, citric acid market share of more than 70%, flavoring agent, can also be used as an antioxidant in edible oils.

3, for environmental protection industry

Citric acid - sodium citrate buffer is used for flue gas desulfurization.China is rich in coal resources, which is the main part of energy. However, there is a lack of effective flue gas desulfurization technology, which leads to serious pollution of atmospheric SO2.Citric acid-sodium citrate buffer solution is a desulfurization absorbent with high development value because of its low vapor, non-toxic, stable chemical properties and high SO2 absorption rate.

4. Used in feed industry

Adding citric acid in the feed of piglets can wean early and increase feed utilization rate by 5% ~ 10%. Adding citric acid in the diet of growing and finishing pigs can increase daily gain, reduce feed to meat ratio, increase protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics.

5. Used in cosmetics industry

Citric acid belongs to a kind of fruit acid, main effect is to accelerate cutin update, often used at emulsion, milk cream, shampoo essence, beautiful white things, anti aging things, whelk things.The regeneration of cutin is helpful to the peeling off of the skin's medium melanin, the narrowing of pores, and the dissolution of blackheads.

6. Used in pharmaceutical industry

Citric acid must have calcium ions in the formation of prothrombin activator and subsequent coagulation process.Citrate ions and calcium ions can form a soluble complex difficult to dissociate, thus reducing the concentration of calcium ions in blood, so that blood coagulation is blocked.It can be used as an in vitro anticoagulant in blood transfusion or laboratory blood samples.
