PURPOSE: The employment of specific process using dialysis film gives lactose hydrolyzate with constant and good taste regardless of the purity of β-galactosidase with simple operation compared to the enzyme-fixation process. n CONSTITUTION: Two chambers divided with a dialysis film such as cellulose tube, cellulose nitrate film, polyvinyl alcohol-Dynel-nylon film, are provided and a solution containing β-galactosidase A, which may be crude or repeatedly used, is charged in the one chamber and another solution containing galactose B, such as whey, desalted whey, defatted milk, butter milk, aqueous lactose or reduced butter milk, is placed in the other chamber. Thus, the other components than A and B do not contact with each other at all and only B is selectively hydrolyzed by A to give the objective hydrolyzate. n COPYRIGHT: (C)1980,JPO&Japio |
