Abstract
There is disclosed a process for the renewal of a deactivated insolubilized glucose isomerase which comprises subjecting an insolubilized glucose isomerase adsorbed onto an anion exchange resin, which has been used for isomerization of glucose into fructose to decrease its activity, to treatments by an aqueous mineral acid solution in combination with an aqueous alkaline solution, an aqueous electrolytic salt solution, an aqueous mineral acid or a mixture thereof to release adsorbed materials from the resin which is converted into a salt type and adsorbing fresh glucose isomerase to the regenerated resin to recover the activity of the insolubilized glucose isomerase.
