Introduce
Malic acid is an organic acid that is found naturally in many fruits, including apples, grapes, and cherries. It is commonly used in the food industry as a flavoring agent due to its sour taste. Malic acid is often used in sour candies, fruit-flavored drinks, and other products that require a tart flavor. It is also used as a pH regulator in some foods, such as canned vegetables and fruit preserves.
In addition to its flavoring properties, malic acid is also used as a preservative in some food products. It can inhibit the growth of bacteria and other microorganisms, which can help to extend the shelf life of certain foods.
