MACHADO, Madalena  and  CURVELO-GARCIA, A.S.. The determination of D(+)-malic acid in wines for low concentrations using the enzymatic method . Ciência Téc. Vitiv. [online]. 1999, vol.14, n.1, pp.15-19. ISSN 0254-0223.

It’s studied the application of the enzymatic method to determining the D(+)-malic acid content in wines for low concentrations. The modification proposed is based on a previous addition of this isomer (50 mg/L). This method modified is applicable for concentrations of 0 to 70 mg/L, with validation parameters equivalents to the method described for concentrations upper 50 mg/L.

Keywords : Vinhos; ácido D(+)-málico; método analítico enzimático.
