Abstract: The present invention is concerned with an edible plant oils from which saturated fatty acids were removed and manufacturing process thereof. In order to remove saturated fatty acids from the edible plant oils; 1) Saturated and unsaturated fatty acids bound on same triglyceride molecules of edible plant oils were segregated each other as alkylesters of fatty acids by conventional transesterification reaction in which edible plant oils were treated with large excess of absolute C1˜C8 alkanol under the presence of catalytic amount of alkali- or alkali-earth metal-C1˜C8 alkoxide. 2) The alkyl-esters of mixed fatty acids were treated with C1˜C8 alkanol solution of urea to remove the alkylester of saturated fatty acids by conventional fractional crystallization as urea complexes of saturated fatty acid-alkylesters.
