Abstract

The present invention concerns an improved method for extracting ß amylases from a soluble fraction of a starch plant said method comprising a step of clarification by microfiltration and a step of concentration and purification by ultrafiltration. This method is characterised in that it uses a protease during the microfiltration step making it possible to greatly reduce the fouling of the membranes used which increases the production time before washing. Simultaneously perfectly clear permeates are obtained which assists with the subsequent ultrafiltration step and makes it possible to improve the transmission of ß amylase. Finally the protease has no negative effect on the ß amylase activity.
