Abstract
Physicochemical properties of four commercial lactase preparations (Galantase, Organase, Lactyme and Lamitase) and an investigational new drug (ORG-FG) were compared. Lactyme showed better results than any other drug in any study and Galantase was not suitable for dispensing. It is recommended that enzyme assay be carried out under the following conditions: reaction temperature 30° and reaction time 10 minutes a sample concentration be measured at OD of 0.30-0.50.
