Abstract
The invention concerns a process for dehydrating glucides and applicable to those glucides of which the molecule includes at least one ketose type group, being characterized in that the glucide is made to react without addition of water with a hydrogen halide, whereupon the hydrogen halide is eliminated by evaporation in order to collect the formed disaccharide anhydride. The invention also relates to novel products characterized by essentially consisting of saccharide anhydrides of which the molecule includes two saccharide cycles linked to each other by two acetal bonds included in a dioxane cycle. As a rule at least one of the saccharide cycles is that of fructose (and may be substituted), and this cycle is linked by a spirane bond to the dioxane cycle. Product application as food additives.
