Malic acid

Malic acid is a naturally occurring organic acid found abundantly in apples, cherries, pears, and many other fruits — the name derives from the Latin for apple (Malum). It contributes the characteristic sharp, fruity tartness of green apples. As a food additive (E296), it is used as an acidity regulator and flavouring in beverages, confectionery, fruit-flavoured products, and some processed foods, where it adjusts pH and enhances perceived fruitiness.

JECFA evaluated malic acid in 1973 and did not establish a numerical ADI, classifying it as not specified. Malic acid is a key intermediate in the citric acid (Krebs) cycle of human cellular energy metabolism, meaning the body handles it continuously at quantities far exceeding any food additive contribution.

Malic acid is approved universally — EU (E296), United States (GRAS), Japan, Korea, and globally. It is one of the most consumer-friendly acidulants available and is widely considered acceptable in clean-label formulations. Unlike phosphoric acid, it contributes no concern around mineral imbalance. Consumers may notice it prominently in sour confectionery and sports drinks, where its sharp flavour profile makes it preferable to citric acid for certain taste targets. There are no known adverse effects at dietary levels of exposure.
