1.For the food industry
Because citric acid has a mild and sour acidity, it is commonly used in the manufacture of various beverages, sodas, wines, candies, snacks, biscuits, canned juices, dairy products and the like. In the market of all organic acids, citric acid market share of more than 70%, flavoring agents, can also be used as antioxidants in edible oils. At the same time improve the sensory traits of food, enhance appetite and promote the digestion and absorption of calcium and phosphorus substances in the body. Anhydrous citric acid is used in large quantities in solid beverages Salts of citric acid such as calcium citrate and ferric citrate are fortifiers that require the addition of calcium and iron ions in certain foods.
2.Used in the chemical and textile industries
Citric acid can be used as a chemical analysis reagent for chemical analysis, as an experimental reagent, a chromatographic reagent and a biochemical reagent; as a complexing agent and a masking agent; for preparing a buffer solution. The use of citric acid or citrate as a builder can improve the performance of the washing product, can quickly precipitate metal ions, prevent the re-attachment of contaminants on the fabric, maintain the necessary alkalinity for washing, and disperse and suspend the dirt and ash; Improves the performance of surfactants, is an excellent chelating agent; can be used as an acid-resistant reagent for testing architectural ceramic tiles.
