| Abstract: | A new technique for extraction of curcumin in curcuma aromatica has been developed, which is based on cellulose enzymolysis. The influences of cellulose amount, treatment time, temperature, pH value, number of extraction and extraction time on the extraction rate of curcumin were studied. The optimum extraction conditions are as the fo1llowing, enzymolysis temperature 50℃, enzyme amount 180 U for 10 g curcuma aromatica, enzymic treatment 120 min, pH value 3.5, number of extraction 2, extraction time 90 min. The extraction rate of curcumin is obviously increased by the cellulose treatment. |
