1.For 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 juices, dairy products and other foods. Citric acid accounts for more than 70% of all organic acid markets. So far, there is no sour agent that can replace citric acid. Citric acid, a molecule of crystal water, is mainly used as an acidic flavoring agent for cool drinks, fruit juices, jams, fruit sugars and cans. It can also be used as an antioxidant for edible oil. At the same time, improve the sensory properties of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus in the body. Anhydrous citric acid is widely used in solid drinks. Salts of citric acid, such as calcium citrate and iron citrate, are fortifiers that need to add calcium and iron ions to some foods. Esters of citric acid, such as triethyl citrate, can be used as non-toxic plasticizers to manufacture plastic films for food packaging. They are sour agents and preservatives in beverage and food industries.
2. For chemical and textile industries
In chemical technology, citric acid can be used as reagent for chemical analysis, experimental reagent, chromatographic reagent and biochemical reagent; Used as complexing agent and masking agent; Used to prepare buffer solution. Using citric acid or citrate as washing aid can improve the performance of washing products, quickly precipitate metal ions, prevent pollutants from re adhering to the fabric and maintain the necessary alkalinity of washing; Disperse and suspend dirt and ash; It is an excellent chelating agent to improve the performance of surfactant; It can be used as a reagent to test the acid resistance of building ceramic tiles.
3.For environmental protection
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 has been a lack of effective flue gas desulfurization process, resulting in serious air SO2 pollution. At present, the annual emission of SO2 in China has been nearly 40 million tons. It is urgent to study effective desulfurization process. Citric acid sodium citrate buffer solution is a desulfurization absorbent with great development value because of its low vapor pressure, non-toxic, stable chemical properties and high SO2 absorption rate.
4.For livestock production
Adding citric acid to piglet feed can wean early, improve feed utilization by 5% ~ 10%, and increase sow litter size. Adding 1% ~ 2% citric acid to the diet of growing finishing pigs can increase daily gain, reduce feed 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, which is suitable for pigs, chickens, fish, shrimp, cattle, sheep, rabbits, silkworms and other animals. It has the characteristics of promoting animal growth, improving product quality, improving disease resistance and survival rate, improving feed conversion rate and shortening feeding cycle.
5.For cosmetics
Citric acid is a kind of fruit acid, its main role is to accelerate the regeneration of keratin, commonly used in emulsion, cream, shampoo, whitening products, anti-aging products, acne products, etc. The renewal of cutin is conducive to the peeling of melanin in the skin, the narrowing of pores, the dissolution of blackheads, etc. For example, Biotherm Living Spring Shumin cleansing mousse can make the skin soft and comfortable, and the skin color is fresh and pure.
6.For sterilization
The combination of citric acid and 80 ºC temperature has a good effect on killing bacterial spores, and can effectively kill the contaminated bacterial spores in the pipeline of hemodialysis machine. Lemon, which enjoys the reputation of "king of Western food", has a strong bactericidal effect and is very 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 can enhance appetite.
7.For medicine
Calcium ions must participate in the formation of prothrombin activator and subsequent coagulation. Citrate ion and calcium ion can form a soluble complex that is difficult to dissociate, which reduces the concentration of calcium ion in blood and hinders blood coagulation. The product is used as an in vitro anticoagulant in blood transfusion or anticoagulation of laboratory blood samples
