malic acid
malic acid, a hydroxy acid obtained as a substance which is sirupy or crystallized with difficulty, and has a strong but pleasant sour taste. it occurs in many fruits, as in green apples, currants, etc. it is levorotatory or dextrorotatory according to the temperature and concentration. an artificial variety is a derivative of succinic acid, but has no action on polarized light, and thus malic acid is a remarkable case of physical isomerism...

Malic acid
Malic acid is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. In its ionised form it is malate, an intermediate of the TCA cycle along with fumarate. It can also be formed from pyruvate as one of the anaplerotic reactions.
Apples contain malic acid, which contributes to the sourness of a green apple. Malic acid can make a wine taste tart, although the amount decreases with increasing fruit ripeness. The process of malolactic fermentation converts malic acid to much milder lactic acid. Malic acid, when added to food products, is denoted by E number E296.
