- Abstract
The aim of this work was to evaluate whether the type of chemically modified starch (cross-linked and/or stabilised) has any effect on its susceptibility to α-amylase and on the physicochemical properties of the resulting maltodextrins of dextrose equivalent (DE) of 6, 11 and 16. The duration of the enzymatic hydrolysis of starch was established experimentally on the basis of a course of individual starch hydrolysis. The type of chemically modified starch was found to have a significant effect on its susceptibility to enzymatic hydrolysis. Native potato starch was more easily hydrolysed than acetylated starch and acetylated distarch adipate. The types of starch most susceptible to enzymatic degradation were distarch phosphate and acetylated distarch phosphate. The results of a chromatographic analysis revealed that the maltodextrins of DE 6 differed from one another significantly in terms of the amounts of each of the DP1-DP5 fractions. The number average molecular weight and the weight average molecular weight of the maltodextrins were decreasing with an increase in DE.
