Malic acid is an organic compound with the formula HO2CCH2CHOHCO2H. It is a dicarboxylic acid that is made by all living organisms, contributes to the pleasantly sour taste of fruits, and is used as a food additive. Malic acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists naturally. Malic acid, when added to food products, is denoted by E number E296. Malic acid is the source of extreme tartness in USA-produced confectionery, the so-called extreme candy. It is also used with or in place of the less sour citric acid in sour sweets.

Encapsulated Malic Acid is a white powder made by spraying hydrogenated vegetable oil over the acid, that allows the malic acid to react in two stages. First stage in the bowl and second stage is released in the baking process. This improves the effectiveness of its preserving qualities to extend shelf life.
