| 摘 要： | 通过响应曲面法,建立了超声波提取石榴皮多酚的二次多项数学模型,探讨了在该最佳提取条件下石榴皮多酚得率与二次提取时间的关系,同时,比较了摇床振荡提取和超声波辅助提取,得出可供工业化生产参考的最佳提取条件。试验得出,两种提取虽然在最大得率上差不多,但超声波提取不需加热,而且总提取时间仅为35min,为摇床振荡提取时间的1/7。PPPs的最佳提取条件为:乙醇体积分数为59%,超声时间(第1次26min,第2次为10min),超声功率90W(超声强度为0.2W/cm)2,就可以达到PPPs的最大提取量为321.26mg/g。

| Abstract: | A second order quadratic equation for Pomegranate Peel Polyphenols (PPPs) ultrasonicwave extraction was built with response surface methodology (RSM) . And the relationship between PPPs yield and its second ultrasonic extraction was further probed into. In addition,The yield of PPPs was compared with the yield by orbital shaker extraction in order to determine the extraction structure,which was appropriate to commercial process. The results showed that the yield by two extractions were much the same,but the... |
