Abstract
To alpha-lactose or an alpha-lactose-containing substance is added a small amount of water and the resulting mixture is subjected to extrusion from a screw extruder under pressure, thereby converting the alpha-lactose into beta-lactose. The beta-lactose or beta-lactose-containing substance thus obtained is dried, pulverized and stored as it is.
