Abstract: A quantitative test method for determining the content of a heat transfer oil mixed with a polar edible oil or fat, wherein the polar edible oil or fat containing a trace amount of the heat transfer oil is diluted with a nonpolar organic solvent, said edible fat or oil is adsorbed onto a column packing medium by passing the dilute solution thereof through a separation column, the heat transfer oil is allowed to flow out from the separation column together with the nonpolar organic solvent, the solution that has thus flowed out is concentrated and subjected to gas chromatography, and a quantitative determination is performed by comparison with the gas chromatography analysis value of a reference solution of heat transfer oil.
