Abstract
A lactase bulk powder and a lactase preparation both have improved storage stability. The stability of a lactase bulk powder is improved by regulating the acceptable amount of glucose and/or galactose, generated during manufacturing the lactase bulk powder, within a preset range. The lactase bulk powder includes lactase, galactose and/or glucose. The total amount of galactose and glucose is more than 0 μmol and not more than 50 μmol per 100,000 U of lactase. The lactase preparation has the lactase bulk powder as an active ingredient.
