Citric Acid Anhydrous

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.


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.
