Abstract:

In order to provide experimental evidences for the rapid identification of kudzu starch, 7 brands of commercial kudzu starch and kudzu starch prepared in our laboratory were subjected to morphological observation and determination of physiochemical properties such as transparency, solubility, viscosity, retrogradation, swelling power, and puerarin, amylose and amylopectin contents and freeze-thaw stability. Results indicated significant differences in physiochemical properties were observed among 8 kudzu starch samples.

Key words: kudzu starch, physio-chemical properties, comparison
