Abstract: A method for reducing the content of a saturated hydrocarbon in oils and/or fats. The method includes subjecting raw material oils and/or fats to a short path distillation treatment under a temperature condition of 50° C. or higher and 270° C. or lower. In the short path distillation treatment, a feed rate of the raw material oils and/or fats to a short path distillation apparatus may be 30.0 kg/h·m2 or less per unit area of an evaporation surface of the short path distillation apparatus. The feed rate may be 5.00 kg/h·m2 or more and 25.0 kg/h·m2 or less per unit area of an evaporation surface of the short path distillation apparatus.

Abstract: The present invention provides a method of producing a refined oil and/or fat, comprising step B: a step of steam-distilling a raw material oil and/or fat at 240° C. or more, wherein a content of saturated hydrocarbons having 20 to 35 carbon atoms in the refined oil and/or fat is 10 ppm by mass or less.

Abstract: Provided is a fat and/or oil composition for heat cooking containing: a fat and/or oil; and 0.02 to 0.08% by mass of an emulsifying agent. The emulsifying agent is at least one selected from the group consisting of a glyceryl monooleate succinate, a glyceryl monooleate citrate, a polyoxyethylene sorbitan monooleate, a sucrose erucic acid ester, and a fatty acid monoglyceride in which a constituent fatty acid contains 47% by mass or more of a polyunsaturated fatty acid. A method of preparing such a fat and/or oil composition for heat cooking includes the steps of: refining a fat and/or oil; and adding 0.02 to 0.08% by mass of an emulsifying agent into the refined fat and/or oil.
