摘要
研究了鼠尾藻提取脂质超声波破壁对脂质提取率的影响。通过单因素实验和正交实验,选出了鼠尾藻细胞破碎的最佳工艺条件:在超声波功率700W、总作用时间为15min、超声时间10s、间隔时间为15s时,脂质提取率最高为1.07%。并比较了其他不同破壁方法,实验结果表明,超微粉碎与超声波破壁方法相结合效果最好。
The lipids extraction from Sargassum thumbergii was studied with the ultrasonic cell-break method. Through the single-factor experiment and orthogonal experiment, the optimum technology was chosen. The results showed, the optimum conditions on cell-break of Sargassum thumbergii with the ultrasonic method were power 700W, total work time 15min, work/interval time lOs/15s and the extracting rate can reach 1.07%. Compared with other cell-break methods, the experimental results showed that the ultramicro smashing and ultrasonic cell-break methods were best.
