PRODUCTION OF TREHALOSE

摘要

PURPOSE:To easily obtain a large amount of trehalose in a short time by heating and drying microbial cell containing trehalose and extracting the denaturated cell with water or an organic solvent. CONSTITUTION:A trehalose-containing microbial cell (preferably cell of yeast of the genus Saccharomyces) is denaturated by heating and/or drying. The denaturated cell is extracted with water or an organic solvent (preferably ethanol) and trehalose is separated from the extracted liquid. The above heat- treatment is preferably carried out at 80-100 deg.C for 2hr and the drying is preferably performed at 90-110 deg.C for 5hr.
