Citric acid and its citrate compounds are widely used in hundreds of applications. Globalproduction of citric acid in 2005 was 1.6 million tons, with China producing approximately40% of the world supply. In the United States, approximately 65% of citric acid use is in thefood and beverage industry. Citric acid is used as an acidulant to impart tartness, to controlpH, as a preservative and antioxidant, as a metal chelator, and to stabilize color and taste.Citrate salts can be used as mineral and metal dietary supplement; for example, calcium citrate is used as a calcium supplement.the second greatest use of citric acid is in detergents andcleaning products. Sodium citrate is used as a builder. Citric acid's ability to chelate metalsmakes it useful as a water-softening agent, which can also assist in cleaning. Approximately10% of citric acid production is used in the pharmaceutical industry. Citric acid's largest usein pharmaceuticals is as an eff ervescent when combined with carbonates or bicarbonates suchas in Alka-Seltzer. As an eff ervescent, it improves tastes, buff ers, and improves solubility ofingredients. It is also used in pharmaceuticals to impart tartness to mask unpleasant medicinalfl avors, maintain stability, and as a buff ering agent.
