Abstract

When dilute solutions (0.4-1.0%) of maltose are heated with mineral acid, significant quantities of isomaltose and nigerose are produced; the yields are greater than that due to acid-reversion from D-glucose. The isolation of minute quantities of nigerose from partial acid hydrolysates of starch-type polysaccharides cannot, in the absence of other supporting evidence, be regarded as proof of the presence of a-1,3-glucosidic linkages.
