Malic acid

Malic Acid is an organic compound, specifically a dicarboxylic acid. It is universally produced by all living organisms, contributes to the tartness of various fruits, and is employed as a food additive. Malic Acid exists in two stereoisomeric forms, L- and D-enantiomers, with only the L-isomer occurring naturally. Salts and esters derived from Malic Acid are referred to as malates. The malate anion serves as an intermediate in the citric acid cycle. Malic acid possesses a clean and smooth flavor profile with a lasting sourness, making it suitable for blending with other food acids, sugars, high-intensity sweeteners, and flavors to create distinct taste sensations. It's important to note that Malic Acid should not be confused with Maleic Acid or Malonic Acid.
