摘 要：
以方竹笋加工剩余物为原料,以总甾醇、β-谷甾醇提取率为考察指标,采用超声波处理法提取竹笋甾醇。在采用单因素试验考察料液比、超声功率、超声时间及颗粒粒径对竹笋甾醇提取率影响的基础上,利用响应面分析法优化超声波处理法提取竹笋甾醇的工艺,在料液比1:31、超声功率410W、超声时间10.5min、颗粒粒径86目条件下,竹笋总甾醇提取率达0.317%,β-谷甾醇提取率达0.249%。

摘 要：
In this study,response surface methodology was used to optimize the ultrasonic-assisted extraction of phytosterol from bamboo shoot scraps.The effects of four variables including solid-to-solvent ratio,ultrasonic power,ultrasonic treatment time and raw material particle size on total phytosterol and β-sitosterol yields were investigated.The optimal extraction conditions were found as follows: 1:31 of solid-to-solvent ratio,10.5 min of ultrasonic treatment time,410 W of ultrasonic power,and 86 mesh of raw material particle size.Under these conditions,the total phytosterol and β-sitosterol yields were 0.317% and 0.249%,respectively.
