Sour Flavoring: Malic Acid

Malic acid is a naturally occurring organic acid found in fruits like apples and cherries. It can be produced industrially through chemical synthesis or fermentation processes, often using maleic anhydride. It provides a tart, sour taste to foods and beverages.

Malic acid is used as an acidity regulator and flavoring agent, adding a sour or tart taste. It is commonly found in candies, fruit-flavored drinks, jams, and baked goods. It can also help enhance the flavor of artificial sweeteners.

Malic acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is naturally present in many foods and is an intermediate in the body's energy production cycle (Krebs cycle). Regulatory bodies like JECFA and EFSA have evaluated malic acid and found it safe for consumption at typical levels. No significant health concerns are associated with its consumption at levels found in food.
