Appearance: White crystal or crystalline powder.
Malic acid Chemical Properties:
White crystal or crystalline powder. The malic acid molecule contains a chiral carbon atom, and there are two enantiomers, namely L-malic acid and D-malic acid. The naturally occurring L-malic acid is widely present in immature fruits such as apples, grapes, cherries, pineapples, and tomatoes; D-malic acid can be obtained by the separation of racemates, and is only used as an experimental chemical. . DL-malic acid is a colorless crystal. The relative density is 1.601, the melting point is 131-133 ° C, and it is decomposed when heated to 150 °C. Soluble in water, alcohol, slightly soluble in ether, insoluble in benzene. Deliquescence easily. This product is a strong acid with a pH of 2.28 in a 0.1mol aqueous solution at 170°C, which can damage mucous membranes and tooth enamel.
