Used in the food industry
Because citric acid has a mild and refreshing acidity, it is widely used in the manufacture of beverages, soda, wine, candy, snacks, biscuits, canned fruit juice, dairy products and so on. Citric acid has a market share of more than 70% in all organic acids market, and there is no acid agent that can replace citric acid. A crystalline water citric acid is mainly used as an acidic flavoring for cool drinks, fruit juices, jams, fruit candies and cans, and can also be used as antioxidants in edible oils. 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 used in solid beverage. Citric acid salts, such as calcium citrate and ferric citrate, are fortified with calcium and iron ions in certain foods. Citric acid esters, such as citric acid three ethyl ester, can be used as non-toxic plasticizers, plastic packaging for food packaging, beverages and food industry sour, preservatives.
Used in chemical and textile industry
Citric acid can be used as a reagent for chemical analysis in chemical technology, as an experimental reagent, chromatographic analysis reagent and biochemical reagent, as complexing agent and masking agent, and used as a buffer solution. Using citric acid or citric acid salts as a builder, which can improve the performance of washing products, can rapid precipitation of metal ions, to prevent contaminants adhere to the fabric, keep washing the necessary basic; the dirt and ash dispersion and suspension; improve the performance of the surfactant is an excellent chelating agent can be used; reagent acid resistance testing of building ceramic tiles.
Formaldehyde pollution clothing has is a very sensitive issue, citric acid and citric acid can be modified into a non formaldehyde anti crease finishing agent, used for cotton fabric finishing. Not only wrinkle proof effect is good, but also the cost is low.
For environmental protection
Citric acid sodium citrate buffer for flue gas desulfurization. China is rich in coal resources, which constitutes the main part of energy. However, there is a lack of effective flue gas desulfurization technology, which leads to serious SO2 pollution in the atmosphere. At present, China's SO2 emissions are nearly 40 million tons, it is urgent to study effective desulfurization process. Citric acid sodium citrate buffer solution is a very valuable desulfurization sorbent because of its low vapor pressure, non-toxic, stable chemical properties and high absorption rate of SO2.
For livestock production
Adding citric acid in piglet feed can early weaning, improve feed utilization rate 5% ~ 10%, increase sow litter size. Adding 1% - 2% citric acid in the diet of growing 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. Citric acid rare earth is a new type of feed additive, is suitable for pig, chicken, fish, shrimp, cattle, sheep, rabbit, silkworm and other animal, promote animal growth, improve product quality, improve the disease resistance and survival rate, improve feed conversion rate, shorten the feeding cycle etc..
Used in cosmetics

"Western-style food enjoys the reputation of" king of the lemon has a strong bactericidal effect, good for health food, plus a scent of lemon, people always love making salad, not only delicious, but also to enhance the appetite.
Used in medicine
Calcium must be involved in the formation of prothrombin activators and subsequent coagulation. Citrate ions and calcium ions can form a soluble complex which is difficult to dissociate, thus reducing the concentration of calcium in blood and blocking the blood coagulation. The product is used as anticoagulant in blood transfusion or anticoagulant in laboratory.
