Lactose in whey is hydrolyzed with an immobilized lactase by a process which involves heating the whey to a temperature of from about 45 DEG to about 90 DEG C. for at least about 15 seconds, centrifuging the heated whey while it is still warm, contacting the centrifuged whey with an immobilized lactase, cleaning the immobilized lactase, and disinfecting the immobilized lactase. Preferably, lactase is immobilized on an inorganic support, and cleaning and disinfecting are carried out respectively by contacting the immobilized lactase with a solution of protease and with a solution of substituted diethylenetriamine. |
