For the use of starch gel like Mook(a Korean traditional gel food), the physicochemical properties and gelatinization patterns of defatted high amylose corn starch were investigated. The crude and total lipid contents of starch decreased by defatting from 0.07%, 0.92% to 0.03%, 0.19%, respectively. But iodine affinity increased from 51.6% to 71.3%. Water binding capacity of starches increased from 104.6% to 117.3% after defatting. Soluble carbohydrate and leached amylose of untreated and defatted starches were increased rapidly above $110^{\circ}C$. The apparent viscosity of starch dispersion using alkali solution increased above 0.3N NaOH solution but the transmittance increased above 0.4 N NaOH. The DSC thermograms of both starches showed broad and double endotherm with relatively low enthalpy, but the second peak of endotherm was larger in defatted starch than in untreated starch.
