Abstract

When isomerizing part of the glucose content of a glucose-containing solution to fructose, the productivity of glucose isomerase immobilized on an SiO.sub.2 carrier is increased considerably by pre-contacting the glucose-containing solution with particles of SiO.sub.2 or aluminum silicate. An apparatus is used having a reaction vessel containing the immobilized glucose isomerase and a pre-column containing the particles of SiO.sub.2 or aluminum silicate.
