| 摘 要： | 以玉米为培养基生产酵母,研究了鼓风干燥、真空干燥和真空冷冻干燥3种干燥方式对酵母活细胞率的影响.结果表明:鼓风干燥能较好地保持玉米酵母活细胞率,并且干燥温度、细胞水分、干燥时间3个因素与酵母活细胞率呈高度线性相关.选择40℃干燥40 min,然后降温至30℃继续干燥40 min,酵母的水分含量为6.8%,酵母活细胞率达到了80%以上.

| Abstract: | The paper produced yeast by use of maize culture medium,and studied the effects of blast drying, vacuum drying and vacuum-freezing drying on the living cell rate of yeast.The results showed that the blast drying method could well keep the living cell rate of the maize yeast,and the drying temperature,the cell water content and the drying time were in highly linear correlation with the living cell rate of yeast.The water content of the maize yeast was reduced to 6.8%,and the living cell rate was up to more t... |
