Functions and Uses of Citric Acid

Use in chemical industry and textile industry: Citric acid can be used as reagent for chemical analysis in chemical technology, as experimental reagent, chromatographic analysis reagent and biochemical reagent. For the food industry: Because citric acid has a mild and refreshing sour taste, it is widely used in the manufacture of various beverages, soda, wine, candy, canned fruit juice, dairy products and other foods. For environmental protection industry: citric acid can be used for flue gas desulfurization. China is rich in coal resources, which is the main part of energy. However, there has been a lack of effective flue gas desulfurization technology, leading to serious air SO2 pollution.

4. For feed industry: adding citric acid to piglet feed can wean early, increase feed utilization rate by 5%~10%; adding 1%~2% citric acid to growing finishing pig diet can increase daily gain, reduce feed to meat ratio, increase protein digestibility, reduce back fat thickness, and improve meat quality and carcass characteristics.
5. Used in cosmetics industry: Citric acid is a kind of fruit acid, which is mainly used to accelerate the renewal of cutin, and is commonly used in lotion, cream, shampoos, whitening products, anti-aging products, acne products, etc.
