Özet
Abstract Acidic hydrolysis of starch, in contrast to enzymatic hydrolysis, gives a very low degree of multiple attack. By making use of this property it seems possible to prepare polysaccharide mixtures with very narrow ranges of molecular weight distribution. In a commercial sample of soluble starch the ratio of weight to number average molecular weights (M̄w/M̄n), which is a direct measure of polydispersity, is decreased from 3.1 to 1.2 by acid hydrolysis followed by ethanol‐water precipitation.
