Abstract
In this work, glyceryl starch was prepared by changing the reactant ratio (v/w) of etherifying agent/starch using chlorinated glycerol as etherifying agent. The molar substitution of glyceryl starch was determined. The modified colorimetric method for the determination of molar substitution was described. The glyceryl starch was characterized by using FT-IR and 1H NMR spectroscopy. Experimental analyses were performed to investigate the effect of dihydroxypropylation on a range of starch properties, including degree of crystallinity, granule morphology, paste clarity, and retrogradation stability and compare them with those of the native corn starch.
