Process for the preparation of a tagatose composition from galactosone

摘要

Preparation of a tagatose composition comprises hydrogenation in the presence of a catalyst of a galactosone composition containing at least 10 (preferably 20-50)% dry matter at a temperature of at least 40 degrees C and a pressure of at least 10 ba An Independent claim is included for preparation of a tagatose composition in which a galactose composition is treated with enzyme having a pyranose-2-oxidase activity in order to obtain a galactosone composition, which is then purified and hydrogenati is effected. The galactose may comprise lactose or lactulose hydrolyzates.
