摘要：
The present invention provides a method of producing oligosaccharides by the reaction between lactose and β-galactosidase from Aspergillus oryzae in which an concentration of lactose in an enzyme reaction mixture is between 50 and 90% (w/v) and a reaction temperature is within the range of 55°C to the temperature at which the β-galactosidase in the reaction mixture is inactivated. This invention therefore makes it possible to obtain the sugar mixture containing high-purity oligosaccharides, small amounts of unreacted lactose and by produced monosaccharides.
