Study on Physico-Chemical Properties of Euryale ferox Starch

Abstract:

Starch is the highest content of Euryale ferox,its structure and characteristic are critical index for application.Some physical and chemical properties of Euryale ferox starch with potato starch and corn starch were compared in this study,including surface structure,freeze-thaw stability,solubility,swelling power,transparency,amyloes and amylopectin content and viscosity characteristic curve.The results indicated that the value of solubility,swelling power,transparency and peak viscosity is lower than that of potato or corn starch,but the pasting temperature value and the content of amylase are superior to those of potato starch or maize starch,the freeze-thaw stability is close to corn starch.
