Title:
ENZYMATIC PROCESS FOR OBTAINING INCREASED YIELD OF LACTOBIONIC ACID
Document Type and Number:
WIPO Patent Application WO2005104859
Kind Code:
A3
Abstract:
A process for obtaining increased yields and/or a reduced reaction time in enzymatic conversion of lactose to lactobionic acid comprising adding to a dairy substrate, such as milk, whey or lac-tose solution, a carbohydrate oxidase, capable of converting lactose to lactobionic acid, wherein the process is performed under stable control of pH.
