Main Usage: Citric Acid is mainly used as acidulant,flavoring agent, preservative and antistaling agent in food and beverage industry.it is also used as antioxidant,plasticizer and detergent in chemical,cosmetics and cleaning industries.
Citric Acid is a weak organic acid, and is triprotic acid. It is a natural preservative and is also used to add an acidic, or sour, taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the citric acid cycle and therefore occurs in the metabolism of almost all living things. It also serves as an environmentally benign cleaning agent and acts as an antioxidant.
Specificity:
Colorless or white crystalline granule or crystalline powder odorless; taste salty and cold, soluble in water, difficulty in ethanol; slightly deliquescence in moist air,pH7.5-9 in 5% aqueous solution, when heated to 150°C,it may lose crystal water.
Appearance:
At room temperature, citric acid anhydrous powders is a colorless translucent crystals or white granulesor 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.
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 readhesion 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.
