| Abstract: | For adapting to the production and establishing standards of jasmine drink,the optimal technological conditions of total flavone extraction in jasmine were studied.And enzymolysis was applied to increase the extraction rate of total flavone.The results indicated that after extraction for 90 minutes under the optimal condition of the temperature at 100 ℃and pH 6.0,then enzymolizing for 60 minutes at 50 ℃ adding 4000 IU mixed-pectinase per kg substrate,the extraction rate of total flavone reached 4.05%,which was 5.7% higher than that of non-enzymolysis dealing,and the filtrating rate was 68% higher than that of non-enzymolysis dealing.The transparency of the liquid was also improved. |
