PURPOSE:To enhance solubility at low temp. by removing free fatty acid and monoglyceride etc., containing in a vegetable oil deodorizing distillate by solvent fractionation and subsequently performing molecular distillation to obtain a distillate which is, in turn, used as an effective component. CONSTITUTION:About 1-10-fold amount of a solvent such as methanol, ethanol or propanol is added to a vegetable oil deodorizing distillate and free fatty acid, monoglyceride, triglyceride and tocopherol are dissolved under heating by solvent fractionation and the whole is cooled at -5-20 deg.C to be allowed to stand for 1-10hr to precipitate a solid substance. The obtained slurry is separated into the solid substance and a liquid part by centrifugal separation or filtering and, after the solvent in the solid substance has been removed, molecular distillation or vacuum steam distillation is performed. The obtained distillate has gelling capacity and can be used as an oil-soluble gelling agent.
