Abstract
PURPOSE: The title lactose useful as an excellent diluent, prepared by growing the crystal of amorphous lactose under specified conditions, and by drying the srystal.
CONSTITUTION: Amorphous lactose is subjected to the atmosphere of RH≥50% to make the crystal growth measured by the X-ray. diffractometry at the diffraction angle 2θ=10.5° in the 110-plane of the β-lactose maximum, and dried to give a crystalline lactose with a high β-lactose content, e.g.≥55 wt.%. The lactose having improved compression moldability is easily prepared and useful as a diluent due to the small increase in volume with moisture absorption.
