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.
