Malic acid is an organic compound with the formula HO₂CCH₂CHOHCO₂H. This dicarboxylic acid is the active ingredient in many sour or tart foods. The salts and esters of malic acid are known as malates. Malate anion is an intermediate in the citric acid cycle along with fumarate. Ca. 1M kg/y are produced by the hydration of maleic anhydride.^[2] Malic acid is found mostly in unripe fruit

History:

Malic acid was first isolated from apple juice by Carl Wilhelm Scheele in 1785. Antoine Lavoisier in 1787 proposed the name acide malique which is derived from the Latin word for apple, mālum.^[3]

Malic acid contributes to the sourness of green apples. Malic acid is present in grapes. It confers a tart taste to wine, although the amount decreases with increasing fruit ripeness. The process of malolactic fermentation converts malic acid to much milder lactic acid.

As Food Additive:

Malic acid, when added to food products, is denoted by E number E296. Malic acid is the source of extreme tartness in so-called "extreme candy", for example Mega Warheads or Sour Punch candies. It is also used with or in place of the less sour citric acid in sour sweets such as Jolly Ranchers, Sweet Tarts and Salt & Vinegar flavor potato chips. These sweets are sometimes labeled with a warning that excessive consumption can cause irritation of the mouth.
