Abstract:The efficient extraction processing parameters of anthocyanin from purple skin cowpea were studied. In order to improve the extraction efficiency of anthocyanin in Vigna unguiculata L.， different processing param－ eters and enzymatic extraction technology were combined in the present study. Furthermore， the extraction effi－ ciency of was analyzed and compared between different methods. The results found that， through orthogonal test and single factor test， pH 3.0， temperature 45 ℃ and 90 min were the best processing parameters for enzymatic extraction of anthocyanin from Vigna unguiculata L.. It can provide scientific references for the extraction of an－ thocyanin from Vigna unguiculata L. and its related studies.
