Modern disaccharide-based artificial sweeteners such as isomaltulose (palati-nose) [229], trehalose, and leucrose [230] can also be separated on a CarboPac PAl [231]. Sweeteners of this kind, with their graduated sweetness, broaden the variety of sweeteners, especially for dietary formulations. Of great importance is the artificial sweetener palatinit, which is synthesized via hydrogenation of isomaltulose. Hydrogenation of isomaltulose leads to an equimolar mixture of a-o-glucopyranosido-l,6-sorbitol (GPS) and -mannitol (GPM). Both compounds can be separated in the same run with sorbitol, mannitol, and isomaltose with a 0.1 mol/L NaOH eluent (Figure 3.237) [232]. 

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 (5), also called Palatinit, is used as a low-calorie sweetener in some countries. It is a mixture of two compounds obtained by the hydrogenation of isomaltulose (6) (Scheme 4.4).15... 

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). 

The 3-pyridinols 74 can be prepared from furfural by reductive amination to furfurylamine and oxidation with hydrogen peroxide [135]. The respective 6-hydroxymethyl derivative 75 was prepared from 4-hydroxymethylfurfural by reductive amination followed by exposure to bromine in water/methanol to give a 2,5-dibromo derivative whose hydrolysis, ehmination of water, and cyclization gave 6-hydroxymethyl-3-pyridinol [136]. Similarly, glucosylated furfuryl amine derived from isomaltulose was converted to 76 (Fig. 13).

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.
