Abstract
Various polysaccharides are prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of mineral acids such as phosphoric, hydrochloric and/or sulfuric acid. In one embodiment, polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels, i.e., from about 0.001% to about 0.09%, more narrowly from about 0.01% to about 0.06%, phosphoric acid. In other embodiments, other mineral acids or mixtures thereof may be employed. In alternate embodiments, a combination of mineral and organic carboxylic acids such as citric acid are employed. Because of the low levels of catalyst used in certain preferred embodiments, minimal or no off-flavors and little color are formed during the course of the reaction.
