寒富苹果渣中多酚类物质超声波辅助提取工艺

Optimization of Ultrasonic Wave Extraction Conditions of Polyphenol from HanFu Apple Pulp

以寒富苹果果渣为原料,以一定浓度乙醇溶液为提取剂,利用超声波辅助法提取苹果渣中的多酚。通过对乙醇浓度、超声波功率、超声波时间、料液比等条件进行单因素试验分析,并通过响应面法得出苹果渣中多酚的回归方程。确定多酚类物质的最佳提取工艺条件为乙醇浓度49%,超声波功率为370 W,作用时间为136 s,料液比为1∶30(g∶mL)。实际平均提取率1.71 mg/g。

In this sdudy,optimum condition of ultrasonic wave exrtaction of polyphenol from HanFu apple pulp with ethanol as its solvent.On ethanol concertration,ultrasonic power,ultrasonic time,solid to liquid ratio conditions of the single factor experiments,though response suiface methodology get the regression equations.The opitmum technological coditions are determined as： solvent concerntration 49 %,ultrasonic 370 W,time136 s,solid to liquid ratio1∶30（m∶mL）.The actual extraction rate is 1.71 mg/g.
