citric acid anhydrous

Citric acid is an organic acid that is a component of all aerobic living organisms—most abundantly, and not surprisingly, in citrus fruit. This weak acid has been used as an additive in processed foods for more than 100 years as a preservative, a sour flavoring, or an emulsifying agent. Because of its effective preservative properties, citric acid can be found in most canned and jarred foods to prevent botulism.

Approximately 50% of the world’s citric acid production is used as a flavor enhancer in beverages. Citric acid is used in soft drinks, teas, juices, and other beverages to create a slightly tart, refreshing flavor and balance sweetness.

The acidic pH of citric acid also makes it useful as a preservative. Since many bacteria are unable to grow in an acidic environment, citric acid is often added to jams, jellies, candy, canned foods, and even meat products as a preservative.
