Abstract The digestion and absorption of a presumably low‐cariogenic carbohydrate derivative, a hydrogenated partial hydrolyzate of starch, has been studied. This contains free sorbitol, plus disaccharides, oligosaccharides and dextrins in which the glucose molecule which had a free aldehyde group prior to hydrogenation has been reduced to sorbitol. The dextrins present are rapidly hydrolyzed by α‐amylase under the formation of di‐and oligosaccharides. Those disaccharides which are composed only of glucose, are completely hydrolyzed by the intestinal disaccharidases and rapidly utilized in the body. The disaccharides containing one molecule of glucose and one of sorbitol, either initially present as disaccharide or formed on the enzymatic cleavage of the dextrins and oligosaccharides, are very slowly hydrolyzed. The glucose bound in this way largely escapes absorption. The sorbitol, whether free or bound, is very slowly absorbed.
