A method was established for determination of amylose in rice,preparing deproteinated starch and defatted plus deproteinated starch, The amylose and purified by the n-butanol recrystallization method,texture analyzer was used to determine the hardness of gels made from deffr-ent proportions of amylose and amylopectin. The standard curve regression equation was y=0.3912x+19.305,R2=0.9953 The recovery ranged from 98.86% to 100.6% and the standard deviation was 2.8%.
