Abstract
The invention relates to a process for the manufacture of a starch hydrolysate of low polymolecularity index which may be used in particular in continuous ambulatory peritoneal dialysis. This process consists essentially in acid and enzymatic hydrolysis of a waxy starch milk and then chromatography on macroporous strong cationic resins of the hydrolysate obtained. The starch hydrolysate is essentially characterized by a polymolecularity index of less than 2.8, a weight-average molecular weight between 5,000 and 22,500 daltons and a number-average molecular weight below 8,000 daltons.
