| Discription | Citric acid anhydrous powders is an important organic acid, colorless crystals, often containing one molecule of water of crystallization, odorless, has a strong acidity, soluble in water. Control the crystallization temperature obtaines anhydrous citric acid. Used in industry, food industry, cosmetic industry. | ||
| Function | At room temperature, citric acid anhydrous powders is a colorless translucent crystals or white granules or white crystalline powder, odorless, very sour taste, slight deliquescence in moist air. Citric acid anhydrous powders can exist in the form of the anhydrate or monohydrate. When heated to 175 ° C,it will decompose to produce carbon dioxide and water, the remaining white crystals. Citric acid is a strong organic acid, 3 H ionization; heating can be decomposed into a variety of products. | ||
| Application | 1. Food industry: mild and refreshing acidity citric acid anhydrous powders is widely used for a variety of beverages, soft drinks, wine, candy, snacks, biscuits, canned fruit juices, dairy products and other food products. 2. Chemicals and textiles: use citric acid or salts thereof as builders, can improve the performance of the washing product, can rapidly precipitate the metal ions, to prevent re-adhesion of pollutants on the fabric maintain washed necessary alkaline; dirt and ash dispersion and suspension; improve the performance of the surfactant. 3. Environmental protection: citric acid - sodium citrate buffer for flue gas desulfurization. 4. Livestock production:citric acid in piglet feed, early weaning, feed utilization increased 5% to 10%, increase the amount of litter pigs. 5. Cosmetics: Citric acid is a kind of acid, the main role is to accelerate the horny update. 6. Sterilization: citric acid and 80 ° C temperature combined effects kill bacterial spores, and can effectively kill bacterial spores of the pollution in the hemodialysis machine line. 7. Medicine: calcium ions participate in the formation of prothrombin activator and coagulation process, citrate ions and calcium ions capable of forming a difficult dissociation of soluble complexes, thereby reducing the concentration of calcium in the blood, a make blood coagulation hindered. The product is used as in vitro anticoagulant in blood samples anticoagulated blood or laboratory. 8.Citric acid anhydrous powders chemical processing or deep processing. | ||
