WebWhy is lactase Immobilised when used to produce lactose free milk? People with lactose intolerance require lactose-free milk. To produce this, immobilised lactase is added to milk. The lactase breaks the lactose down into glucose and galactose. The glucose and galactose produced are then easier to absorb. WebThe major emphasis of this article is on the use of immobilized enzymes in the food industry.
