Citric acid is often used to make all kinds of beverages, soda, wine, candy, snacks, biscuits, canned fruit juice, dairy products and so on. Among all organic acids on the market, citric acid has a market share of more than 70%. It can also be used as a flavoring agent and an antioxidant in 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, such as calcium citrate and iron citrate. It is a fortifier that needs to add calcium and iron ions to some foods.
Function
Food industry
Citric acid is the largest organic acid produced by biochemical methods in the world. Citric acid and salts are one of the pillar products of the fermentation industry, mainly used in the food industry, such as sour agents, solubilizers, buffers, antioxidants, Deodorant, flavor enhancer, gelling agent, toner, etc.
Metal cleaning
Citric acid is an organic acid produced by microbial fermentation. It is widely used in detergent production. Its specificity and chelation function play a positive role.
Fine chemical industry
(1) Citric acid is a kind of fruit acid. Its main function is to accelerate the renewal of keratin. It is often used in lotions, creams, shampoos, whitening products, anti-aging products, acne products, etc.
(2) Citric acid can be used as chemical analysis reagent in chemical technology, used as experimental reagent, chromatographic analysis reagent and biochemical reagent; used as complexing agent, masking agent; used to prepare buffer solution.
(3) 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, and maintain the necessary alkalinity for washing; disperse dirt and ash And suspension; improve the performance of surfactants, is an excellent chelating agent;
(4) It can be used as a reagent for testing the acid resistance of building ceramic tiles.
(5) Citric acid-sodium citrate buffer is used for flue gas desulfurization.
(6) Citric acid can be used as a formaldehyde-free dyeing finishing agent. Triethanolamine can prevent citric acid from decomposing and dehydrating to form unsaturated polycarboxylic acid during the fabric baking process, thereby effectively inhibiting the yellowing of the fabric.
Sterilization
The combined effect of citric acid and 80°C temperature has a good effect of killing bacterial spores, and can effectively kill the contaminated bacterial spores in the hemodialysis machine pipeline.
Animal breeding
(1) Increase feed intake and promote digestion and absorption of nutrients
(2) Promote the health of the intestinal flora of livestock and poultry
(3) Enhance the anti-stress and immune ability of livestock and poultry
(4) Used as anti-mold agent and antioxidant.
Application
1. Widely used in all kinds of drinks, soft drinks, wine, candy, snacks, biscuits, canned fruit juices, dairy products, also can be used as a cooking oil antioxidants. Anhydrous citric acid used in solid drinks a lot.
2. Citric Acid is a good rock mixture, Can be used for testing the acid resistance of ceramic tile of architectural pottery reagents.
3. Citric acid and sodium citrate buffer used for flue gas desulfurization.
4. Citric acid is a kind of fruit acid, can be used to accelerate the cutin renewal, commonly used in lotions, creams, shampoo, whitening, anti-aging products, acne products.
5. Citric acid is an important organic acid, containing citric acid monohydrate and anhydrous citric acid.Because of its mild and refreshing acidity.
