Abstract
An aqueous medium in which glucoamylase is dissolved, is contacted with nitrogen-functionalized amorphous precipitated silica having a pore diameter at the maximum of the volume pore size distribution function of from about 7 to about 100 nanometers, whereby at least a portion of the glucoamylase is adsorbed by the nitrogen-functionalized amorphous precipitated silica. The process is particularly suitable for removing glucoamylase from draught beer.
