Description:

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 153℃. Translucent colorless crystals obtained from water solution is a water softening, the density is 1.542.75 at about 100℃melting. 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.

Usage:

1. Mainly used as a food sour agent, also used in the preparation of pharmaceutical cooler, detergent additives, etc.
2. Used as a reagent, chromatographic analysis reagent and biochemical reagent, and can also be used to buffer preparation. For the food industry in particular, as acidifying agent, pH buffer, and other compounds together to preserve the agent. In detergent industry, it is the ideal substitute for phosphate. Acid pickling of boiler chemical cleaning agent, boiler chemical cleaning and rinsing agent. Mainly used in food sour agent, but also for the preparation of pharmaceutical freshener detergent.
3. Citric acid has much function, the most widely used for sour agent. It has higher solubility and metal ion chelating ability is strong, can be used for various types of food, according to production needs proper use. In addition, this product can also as antioxidant synergist, synergist compound potato starch bleaching agent and antiseptic.
4. Used as analytical reagent.
5. Widely used as food, drink sour agent and drug additives. Can also be used as a cosmetic, metal cleaning agent, mordant, nontoxic plasticizing agent and boiler antiscaling agent of raw materials and additives. The main salt products have citric acid sodium, calcium and ammonium salt and sodium citrate is a blood anticoagulant, ferric ammonium citrate can be blood drug.
