摘要
以啤酒废酵母细胞为原料,以海藻糖得率为衡量指标,对比分析得出:啤酒废酵母细胞中海藻糖分解酶适宜灭活方法为微波灭酶900W、4min;通过L(934)正交实验设计,优化出三氯乙酸溶液浸提海藻糖的最佳技术参数为:提取温度为65℃,料液比1∶22,浸提时间120min,海藻糖得率达到11.07%。
The yield of trehalose from waste beer barrn cells was used as the measuring index in the experiments. 4 rain 900 W microwave could exterminate the activity of decomposing enzyme of trehalose in waste beer barm cells. The optimum technical parameters were summed up as follows through L9 （34）orthogonal experiments： extraction temperature at 65 ℃, solid-liquid ratio as 1：22 and lixiviation time was 120 min. As a result, the yield oftrehalose could reach up to 11.07 %.
