Abstract: Corn starch was hydrolyzed with α-amylase and glucoamylase to prepare microporous starch.The adsorption capacities of original starch and the microporous starch to methylene blue(hydrophobic substance) and safranine T(hydrophilic substance) were compared respectively,and the adsorption stabilities and saturated adsorption capacities of the two starches were evaluated at different temperatures and concentrates.

Key words: microporous starch, saturated adsorption capacity, methylene blue, safranine T
