Milk industry lactose hydrolysis

Another established application in the dairy industry is the hydrolysis of lactose in milk and whey by lactases. Diminished digestibility problems, increased sweetness and prevention of lactose-crystal formation are the results. The lactose hydrolysis is worked out as a case later in this chapter (section 3.6). 

Hydrolysis of beta-D-galactosidic linkage of lactose milk (Industrial scale) [2]... 

Silanized and glutaraldehyde-activated sub-micron ferrite particles have been used to immobilize j3-D-galactosidase. The immobilized enzyme was used for the hydrolysis of lactose in whole milk, from which the enzyme is readily recovered magnetically. The immobilized j3-D-galactosidase is of potential industrial importance hydrolysis improves some processed dairy products and there are also nutritional products requiring modification for people with lactose intolerance.
