DEFINITION

Classification: 536/46

(under subclass 45) Compounds which are any nitrogen containing derivatives of various gummy polysaccharides produced by thermal or acid degradation of starch.

(1) Note. Dextrins are carbohydrates, intermediate between starch and sugars. Degradation of dextrins yields maltose and glucose.

(2) Note. For classification here the nitrogen containing derivatives of dextrin have to be gummy polysaccharides;

sugars are not provided for herein.
