Abstract
Isomaltulose-forming microorganisms are immobilized on a carrier that is a weakly basic anion exchange substance in the form of a substantially non-compressible porous particulate solid material, and are used for isomerization of sucrose to isomaltulose. A preferred carrier contains microfibers or microparticles of diethylaminoethyl cellulose adherently bound by agglomeration with polystyrene. The isomerization may be a continuous conversion in one or more columns packed with the carrier. Isomaltulose may be hydrogenated to form isomalt for use in sweetening. Microorganisms can be immobilized on the carrier by feeding microorganisms to a column containing the carrier. After microorganism immobilization, the carrier may be treated with a crosslinking and/or flocculating compound. Regeneration of the carrier is carried out by removing microorganisms, washing and reloading with fresh microorganisms.
