Acetylated starches with DS above 0.22 showed morphological
changes in the granules. However, oxidation did not affect the barley
starch morphology. Acetylation and oxidation reduced relative
crystallinity, enthalpy, swelling power, pasting temperature and
viscosity of barley starches. Acetylated starches were more stable
to heating and shearing than native starch. While oxidized starches
were less stable to these parameters than native starch. Oxidized
starches had a significant increase in solubility when compared
to native starch
