Distributed in nature Citric acid is widely distributed in nature, found in plants such as lemon, orange, pineapple, currant, raspberry, Grape Juice fruit and animal bones, muscles, blood. Citric acid is synthesized with sugar, starch, molasses, grapes and other sugary material fermentation, can be divided into anhydrous and two kinds of pure hydrate. Citric acid is a colorless transparent crystal or white powder, odorless, has an attractive acidity. Translucent colorless crystals obtained from concentrated aqueous solution of heat in the anhydrous melting point is 153ºC. Translucent colorless crystals obtained from water solution is a water softening, the density is 1.542.75 at about 100ºCmelting. One water compoment can loss water in dry air. It is a strong organic acid. It is soluble in water, ethanol and ether. Used in the manufacture of drugs, soda, candy, also used as a metal cleaning agent, mordant.
Many kinds of fruits and vegetables, especially citrus fruits contain more citric acid, especially lemon and lime -- they contain a lot of citric acid, after drying, the content is up to 8% (in the juice content is about 47 g / L). In the citrus fruits, the content of citric acid is between 0.005 mol / L of orange and grape and 0.30 mol / L of lemon and lime . The content changes different from cultivars and plant growth.
