Citric acid is a weak organic acid that is produced as a white crystalline powder. It is a natural food preservative that is also used to add an acidic, or sour taste to foods and soft drinks. In biochemistry, it is important as an intermediate in the Krebs (citric acid) cycle and therefore occurs in the metabolism of virtually all living things. Citric acid can also be used as an environmentally benign cleaning agent.
TCC’s citric acid is a useful ingredient in beverages, jams, jellies, candies and frozen foods. It is also added in gelatin and fruit-based desserts as well as in canned vegetables and meat products. Citric acid preserves food and enhances flavor. It is one of the most useful ingredients in the food and beverage industries.
Citrate salts of various metals are used to deliver those minerals in a biologically available form in many dietary supplements. The buffering properties of citrates are used to control pH in household cleaners and pharmaceuticals.
Citric acid’s ability to chelate metals makes it useful in soaps and laundry detergents. By chelating the metals in hard water, it lets these cleaners produce foam and work more efficiently without the need for water softening.
Citric acid is recognized as being safe for use in food by all major national and international food regulatory agencies. It is naturally present in almost all forms of life, and excess citric acid is readily metabolized and eliminated from the body.
