摘　　要： 对从啤酒废酵母中提取海藻糖的工艺进行了研究,在乙醇浓度为60%(v/v),提取温度为80±1℃,提取时间为30min,酵母质量浓度为100g/L条件下,海藻糖的提取率可达91.71%。采用活性炭脱色,阴阳离子交换除杂,经浓缩、结晶、干燥,制成的海藻糖成品纯度为96.85%。 Extraction technology of trehalose from waste beer yeast was studied in this paper. The extraction rate of trehalose could reach 91.71 % under the following conditions: alcohol concentration 60 %(v/v),temperature at 80±1 ℃,90 min extraction time and the concentration of yeast as 100 g/L.The solution was decolorized by active carbon,and then desalted and decolorized by ion-exchange technique, then condensed and crystallized and dried. The purity of produced trehalose was as high as 96.85 %.
