摘　　要：以啤酒废弃酵母泥为实验材料,以海藻糖为研究对象,蒸馏水为提取溶剂,利用对比分析和多元线性回归正交组合设计方法,优化出微波辅助提取啤酒废弃酵母细胞中海藻糖的工艺参数为:料液比1∶30,微波时间3 min,微波功率600 W,水浸提温度100℃,水浸提时间3.5 h时,海藻糖得率达到了9.24%;构建出海藻糖提取的工程化回归模型。This paper researched on beer waste yeast aimed at getting trehalose which extracted by distilled water.Contrast analysis and multiple linear regressions were used to optimize the technology parameters by microwave assisted extracting in beer waste yeast.The optimal technological parameters were dosage liquor rate at 1∶30,microwave treatment time at 3 min,microwave power at 600 W,diffusion temperature at 100 ℃,diffusion time at 3.5 h,and the yield of trehalose reached up to 9.24%.Engineering regression model of extracting trehalose from waste beer yeast was set up.
