Isomalt from isomaltulose

Production of isomalt. Although isomaltulose (Palatinose ) is a sugar replacer itself, most of the product is currently used as a precursor for the production of the sugar replacer isomalt. If isomaltulose (Palatinose ) is processed to isomalt by hydrogenation wet crystals from crystallization are directly used. 

Isomalt, a mixture of a-D-glucopyranosyl-l,l-D-mannitol dibydrate and a-D-glucopyranosyl-l,6-D-sorbitol, is obtained by hydrogenating isomaltulose which is en2ymatically derived from sucrose (102). 

Disaccharides such as isomaltulose (6-a-D-glucopyranosyl-D-fructo-furanose), obtained in one step from sucrose by bioconversion (Scheme 12),44 Isomalt , the hydrogenated derivative of isomaltulose and trehalulose (1-a-D-glucopyranosyl-D-fructopyranose) have been shown to be interesting substrates for chemistry.45... 

Isomalt is produced from food-grade sucrose in a two-stage process. Beet sugar is converted by enzymatic transglucosida-tion into the reducing disaccharide isomaltulose. This undergoes catalytical hydrogenation to produce isomalt. 

Isomalt is a mixture of two isomeric polyols which result from hydrogenation of the keto group of isomaltulose. The starting material, isomaltulose, is obtained by bacterial conversion of sucrose (Scheme 1).
