Method for preparing trehalose
The invention belongs to the fields of fermentation and production of microorganisms, and in particular relates to a method for improving the yield of trehalose in a yeast strain by a dry dehydration method. A method for preparing the trehalose comprises the following steps of: fermenting the yeast strain at the temperature of between 30 and 35 DEG C, performing enlargement culture, collecting thalli, performing extrusion dehydration, and performing forced air drying on the dehydrated thalli at the temperature of between 30 and 95 DEG C until the water content of the thalli is 5 to 25 percent; performing ultramicro crushing on the dried thalli to obtain wall breaking thalli powder; and dissolving the thalli powder in water, uniformly mixing, performing ultrafiltration by using an ultrafiltration membrane, and collecting filtration liquor to obtain a solution in which the trehalose is dissolved. By the method, the water content of the yeast thalli is gradually reduced through forced air drying, the yeast thalli is stimulated to synthesize the trehalose in large quantities under a dry environment, the accumulation amount of the trehalose in the yeast thalli is improved, and the content of the trehalose in a yeast cell can be improved by 85 percent.
