Abstract
β-Limitdextrin was prepared from amylopectin by the action of barely β-amylase. The action of salivary α-amylase on β-limitdextrin was examined by the iodine potentiometric titration method. The titration curves showed to be of the same type as that of amylopectin. It was demonstrated that the salivary α-amylase split the internal α-1, 4-linkages in amylopectin and β-limitdextrin in the same way in-dependently of the α-1, 6-linkage of all end chaine.
