The invention provides a determination method for polar components in edible oil, which relates to determination methods for edible oil. The method comprises the following steps: dissolving a semisolid or solid sample, carrying out filtering, then dissolving an oil sample in a mixed solution of petroleum ether and ether and allowing a volume to be fixed at 10 mL; drying silica gel, cooling the silica gel to room temperature, adding water, transferring the silica gel to the syringe of an injector, compacting the silica gel, adding sea sand or quartz sand and then adding the mixed solution of petroleum ether and ether along the wall of the syringe so as to wet the silica gel; when the surface of the mixed solution of petroleum ether and ether and the surface of sea sand or quartz sand are parallel and level, dissolving the oil sample in a chromatography column, adding the mixed solution of petroleum ether and ether for elution of nonpolar components, collecting eluate to a flask or beaker and carrying out drying by distillation and then weighing; studying separation effects of the nonpolar components; and carrying out calculation.
