Polyphenols from Grape Skin:Optimization of Ultrasonic-assisted Extraction Process by Response Surface Methodology and Antioxidant Activity Evaluation
以酿酒葡萄皮渣为原料采用超声辅助法提取葡萄皮渣多酚,在单因素试验基础上固定超声功率100W、乙醇体积分数40%,采用三因素三水平的响应面试验优化设计方法,研究液料比、提取时间和超声温度对多酚得率的影响,依据回归分析得到最佳提取工艺条件为液料比16:1(mL/g)、超声提取时间57min、超声温度50℃。在此条件下葡萄皮渣多酚提取量为(42.51±1.21)mg/5g。以水溶性VE为对照物,通过DPPH法和铁氰化钾法对葡萄皮渣多酚的抗氧化活性进行体…查看全部>>
Response surface methodology was employed to optimize the ultrasonic-assisted extraction of polyphenols from grape skin as a byproduct of wine making.On the basis of one-factor-at-a-time experiments,through which the optimal ultrasonic power and ethanol concentration were found to be 100 W and 40%,respectively,polyphenol yield was investigated by response surface methodology with respect to liquid-to-material ratio,extraction time and temperature at three le…查看全部>>
