| Abstract: |
| 【Objective】 The study is to improve the condition for the extraction of anthocyanins from grape pomace.【Mehtod】 Single-factor and orthogonal experiments were adopted to establish the optimal conditions for the extraction of anthocyanins, with the yield of extraction as index.【Result】 The results showed that:with 0.1% HCl (V/V) MeOH as extractant assisted by ultrasonic extraction at 40 ℃,the extraction time is 50 min,the ratio of grape pomace and extraction being 1∶7 and twice-time extraction the best.The sequence of actors that worked on the yield of anthocyanins were as below:extraction number> extraction vol.> extracted time> extraction temperature.【Conclusion】 We obtainted the condition for the extraction of anthocyanins from grape pomace,yiefd of extraction is 73.10%. |
