At room temperature, citric acid is a white crystalline powder, odorless and very acidic in taste [2], with a density of
1.542g/cm3 and a melting point of 153-159ºC. Above 175ºC, it decomparts and releases water and carbon dioxide. Citric acid is easily soluble in water, with a solubility of 59% at 20 ° C and a pH of 2.1 in its 2% aqueous solution.
Citric acid commonly used in the manufacture of various beverages, sodas, wines, candies, snacks, biscuits, canned juices, dairy
products and the like. In the market of all organic acids, citric acid market share of more than 70%, flavoring agents, can also
be used as antioxidants in edible oils. At the same time improve the sensory traits of food, enhance appetite and promote the
digestion and absorption of calcium and phosphorus substances in the body. Anhydrous citric acid is used in large quantities in solid beverages Salts of citric acid such as calcium citrate and ferric citrate are fortifiers that require the addition of
calcium and iron ions in certain foods
Application
Mainly used in food, beverage, pharmaceutical industry, as acidulant, flavoring agent and preservative, preservative, pharmaceutical excipients; In the chemical industry, cosmetics industry.
