The DL-Malic acid is a white crystalline powder, highly soluble in water, containing three hydroxyls in its chemical structure. It appears in relatively high amounts in several fruits and vegetables, while only the L-isomer exists naturally.


Malic acid, a carboxylic acid most found in fruits, is a smooth taste substance used as flavoring and preservative agent in foods, although not as used as citric acid.  There are no studies focusing in quantitative results or investigations on its physicochemical properties, useful to the food industry, or even the confirmation of its calcium chelating, buffer texturizer and antioxidant alleged properties.  Thus, the aim of this work was the assessment of most physicochemical properties of malic acid, solid and in solution, that could be useful to the food industry understand its real potential.
