citric acid

Product Details

1. For food industry

Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, soft drinks, wine, candy, snacks, biscuits, canned juice, dairy products and other foods. In the market of all organic acids, the market share of citric acid is more than 70%. So far, there is no sour agent that can replace citric acid. One molecule of crystalline water citric acid is mainly used as an acidic flavoring agent for refreshing beverages, fruit juices, jams, fruit candies and canned food, and can also be used as an antioxidant for edible oils. At the same time, it improves the sensory properties of food, enhances appetite and promotes the digestion and absorption of calcium and phosphorus in the body.

2. Used in chemical, pharmaceutical and textile industries

In chemical technology, citric acid can be used as a reagent for chemical analysis, as an experimental reagent, a chromatographic analysis reagent and a biochemical reagent; as a complexing agent, masking agent; used to prepare buffer solutions. Using citric acid or citrate as a builder can improve the performance of washing products, can quickly precipitate metal ions, prevent pollutants from re-attaching to the fabric, maintain the necessary alkalinity for washing; disperse and suspend dirt and ash; It is an excellent chelating agent to improve the performance of surfactants; it can be used as a reagent for testing the acid resistance of architectural ceramic tiles.

Citric acid-sodium citrate buffer is used for flue gas desulfurization. my country is rich in coal resources, which constitute the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, resulting in serious atmospheric SO2 pollution. At present, the annual emission of SO2 in my country has reached nearly 40 million tons, and it is a top priority to study an effective desulfurization process. Citric acid-sodium citrate buffer solution is a desulfurization absorbent with great development value due to its low vapor pressure, non-toxicity, stable chemical properties, and high absorption rate of SO2.

4. For livestock production

Adding citric acid to piglet feed can lead to early weaning, improve feed utilization by 5% to 10%, and increase sow litter size.

Adding 1% to 2% citric acid to the diet of growing-finishing pigs can increase daily gain, reduce feed to meat ratio, improve protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics. Rare earth citrate is a new type of high-efficiency feed additive, suitable for pigs, chickens, fish, shrimps, cattle, sheep, rabbits, silkworms and other animals. It can promote animal growth, improve product quality, improve disease resistance and survival rate. Improve the feed conversion rate and shorten the feeding cycle. At this point we have to admit that citric acid has a wide range of uses.

5. For cosmetics

Citric acid is a kind of fruit acid. Its main function is to speed up keratin renewal. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, and acne products. The renewal of keratin is helpful for the exfoliation of melanin in the skin, the reduction of pores, and the dissolution of blackheads. For example, Biotherm's Moisturizing Mousse Cleansing Mousse leaves the skin soft and comfortable, leaving the complexion fresh and pure.

6. For sterilization

The combined action of citric acid and 80°C temperature has a good effect of killing bacterial spores, and can effectively kill the bacterial spores polluted in the pipeline of the hemodialysis machine. Lemon, known as the "King of Western Food", has a strong bactericidal effect and is good for food hygiene. Coupled with the fragrance of lemon, people have always liked to use it to make cold dishes. It is not only delicious and refreshing, but also increases appetite.

7. For medicine

In the formation of prothrombin activator and the subsequent coagulation process, calcium ions must be involved. Citrate ions and calcium ions can form a soluble complex that is difficult to dissociate, thereby reducing the concentration of calcium ions in the blood and hindering blood coagulation. This product is used as an in vitro anticoagulant during blood transfusion or laboratory blood sample anticoagulation.
