Synonyms
Hydrogenated starch hydrolysate, hydrogenated glucose syrup and polyglucitol
Definition
A mixture consisting mainly of maltitol and sorbitol and lesser amounts of hydrogenated oligo- and polysaccharides and maltrotriitol. It is manufactured by the catalytic hydrogenation of a mixture of starch hydrolysates consisting of glucose, maltose and higher glucose polymers, similar to the catalytic hydrogenation process used for the manufacture of maltitol syrup. The resulting syrup is desalted by ion exchange and concentrated to the desired level. Einecs Chemical name Sorbitol: D-glucitol Maltitol: (α)-D-Glucopyranosyl-1,4-D-glucitol Chemical formula Sorbitol: C Maltitol: C Molecular weight Sorbitol: 182,2 Maltitol: 344,3 Assay Content not less than 99 % of total hydrogenated saccharides on the anhydrous basis, not less than 50 % higher molecular weight polyols, not more than 50 % of maltitol and not more than 20 % of sorbitol on the anhydrous basis.
Description
Colourless and odourless clear viscous liquid
Identification
Solubility Very soluble in water and slightly soluble in ethanol Test for maltitol Passes test Test for sorbitol To 5 g of the sample add 7 ml of methanol, 1 ml of benzaldehyde and 1 ml of hydrochloric acid. Mix and shake in a mechanical shaker until crystals appear. Filter the crystals and dissolve in 20 ml of boiling water containing 1 g of sodium bicarbonate. Filter the crystals, wash with 5 ml of a water-methanol mixture (1 in 2) and dry in the air. The crystals of the monobenzylidine derivative of sorbitol so obtained melt between 173 and 179 °C.
