海藻糖提取工艺的研究

研究从面包干酵母中提取海藻糖。经多次实验，最佳工艺条件为：乙醇浓度为50％、提取温度为80℃、时间为1．5h、固液比为1：15。提取液经超滤后再经活性碳、离子交换及脱色除杂。精制后糖液用95％工业酒精结晶，条件为：温度40℃，料液比为1:4（V／V）同时不断搅拌。

The conditions of the Treharoses extraction from the bakers active dried yeast were studied．With experiments the following conditions wore selected：alcohol concentration 50％． temperature 80℃，the ratio between yeast and alcohol 1：15 Afterthis the solution were modified with ultrathin decolourizing carbon，ion exchange Then treharoses is crystallized with 95％ alcohol，and the crystallized conditions were：temperature 40℃，the ratio between solution and alcohol 1：4．
