Axit Citric

Food Additives As a food additive, citric acid is used as a flavoring agent and preservative in foods and beverages, especially soft drinks. It is denoted by an E number E330. Citrate salts of various metals are used to deliver these minerals in a biologically usable form in many nutritional supplements. The buffering properties of citrates are used for pH control in household cleaners and in pharmaceuticals. In the United States, the purity of citric acid required as a food additive is defined by the Food Chemical Codex (FCC), published in the United States Pharmacopeia (USP).

Water softening The ability of citric acid to chelating metals makes it useful in soaps and detergents. By chelating metals in hard water, it causes these cleaners to foam and work better without the need to soften the water. In a similar fashion, citric acid is used to regenerate ion exchange materials used in water softeners because it precipitates accumulated metal ions as citrate complexes.

Other Citric acid is used in biotechnology and the pharmaceutical industry to passivate high purity pipeline systems (instead of using nitric acid). Nitric acid is considered hazardous and difficult to handle when used for this purpose, while citric acid is not. Citric acid is the active ingredient in some kitchen and bathroom cleaning solutions. Commonly used as a buffer to increase the solubility of brown heroin. Citric acid is one of the chemicals required for the synthesis of HMTD, a heat, friction, and impact sensitive explosive similar to acetone peroxide .

Citric acid can also be added to ice cream to keep fat globules separate, as well as added to fresh lemonade recipes on the spot.

Citric acid is also widely used in winemaking as a substitute or supplement when fruits with little or no natural acidity are used.

Citric acid is also used as a second rinse (after the water of rendering) in the treatment of photographic film prior to the application of fixative water.

Citric acid is also used as one of the active ingredients in the production of antiviral tissues

Citric acid is also used as the primary ripening agent in the early stages of mozzarella cheese production.
