The origin of the substantial stabilization of the color of the natural anthocyanin malvidin-3-glucosyl chloride (Oenin) in aqueous micellar SDS solutions has been elucidated by employing laser flash photolysis and pH-jump techniques to determine all four rate constants involved in the acid−base and hydration reactions of Oenin. These rate data show that the pronounced stabilizing effect of SDS micelles on the color of aqueous solutions of oenin, as measured by the shift in the bleaching… CONTINUE READING
