Malic Acid Vs. Citric Acid

Both citric acid and malic acid are on the GRAS, or Generally Recognized as Safe, list maintained by the U.S. Food and Drug Administration. Citric acid as well as its potassium, sodium and calcium salts is classified as GRAS for general purpose use in foods. Malic acid also is approved for general purpose or “miscellaneous” use.

Citric Acid

Citric acid is the most commonly used acidulant for food. It’s been used for well over a century. Citric acid used to be mainly extracted from fruits like lemons and limes. These days it’s most often made using fermentation technology which involves mold fermentation of sugar solutions.

Malic acid occurs naturally in fruits such as apples and berries. It’s also the second major acid in citrus fruits, following citric acid. Malic acid used in foods most often is created via hydration of maleic acid and fumaric acid. Malic acid is considered 78 to 83 percent as tart as citric acid 23.

Common Citric Acid Uses

Citric acid has many uses in food. It serves as a flavor enhancer, a pH regulator, a preservative, and as an antioxidant synergist with erythorbic or ascorbic acid, such as:

  • on fresh or frozen fruit
  • which prevents color
  • flavor degradation

Citric acid and its salts also prevent crystallization in honey, are used in clarifying fruit juices and to stabilize spices. Citric acid is most often used in beverages. In fact, about 65 percent of citric acid consumed is used in drinks. You’ll commonly find it in carbonated drinks. It’s also common in wine coolers, cocktail mixers and iced tea. You’ll also find it in candy, dried fruit, canned fruit, jams and jellies and gelatin.
