【摘要】 实验研究了超声-微波协同皂化萃取茄尼醇的工艺条件,确定了其最适工艺参数为:在超声开的条件下,皂化时间60 min,微波功率40 W,氢氧化钠与烟叶浸膏的质量比为1∶2,在此优化条件下茄尼醇皂化回收率为126.3%。与其它皂化法相比,超声-微波协同皂化萃取法具有节省时间、节约能量、茄尼醇回收率高等优点。更多还原

【Abstract】 Ultrasonic-microwave synergistic saponification technique was applied to extract solanesol.The effects of main factors on saponification reaction were discussed and the optimum saponification conditions were as followed:the saponification time was 60 min,the microwave power was 40 W,the mass ratio of sodium hydroxide to tobacco extract was 1∶2,and the ultrasonic was turned on.The results showed that under the optimized condition,the recovery rate of solanesol was 126.3%.Compared with other saponification methods,the ultrasonic-microwave synergistic saponification technique was a better method for solanesol extraction with less time and higher recovery rate of solanesol.更多还原
