AMYLOSE/AMYLOPECTIN SIMPLE DETERMINATION IN ACID HYDROLYZED TAPIOCA STARCH
Analysis of the shift of wavelength máximum using a rapid colorimetric method was used to determine the ratio of amylose:amylopectin (Am:Ap) in acid-hydrolyzed tapioca starch. The absorbance máximum of 600 nm (Am:Ap of tapioca starch ≈ 22:78) moved to shorter wavelengths (590, 585, 570, 56...
