Citric acid is organic acid in the first big acid, due to the physical properties, chemical properties, derivative performance, is widely used in the food, cosmetic, pharmaceutical, etc of the industry's most important organic acid
Citric acid
A colorless translucent crystalline acid, C6H8O7, principally derived by fermentation of carbohydrates or from lemon, lime, and pineapple juices and used in preparing citrates and in flavorings and metal polishes. Today, essentially all of the commercial citric acid is produced by surface or submerged fermentation by mold (Aspergillus niger) and submerged fermentation by yeast (Candida guilliermondii, C. Lipolytica), using a variety of substrates including sucrose, molasses, corn syrup, enzyme-treated starch, and normal paraffins.
Application:
Used as anticoagulin, chemical reagent, food additive, developer, buffer emulsifying agent, stabilizing agent and used in nonhydrogen electroplation as well as widely in tail gas absorption process of sulfur dioxide for chemical and metallurgy industries. Its absorptivity reaches 99%. The waste absorbed may be regenerated into sulfur dioxide liquid and potassium citrate for cyclic utilization. The daily-use chemical detergent with potassium citrate. As raw material instead of sodium phosphate trimer, it is non-toxic and non-pollution. It also may be used as buffer agent in cosmetic production.
