An alcohol extraction process for edible oil

An alcohol extraction process for edible oil is provided, belonging to the technical field of edible oil preparation. The process is characterized in that the process includes a step of crushing an oil-bearing material, mixing the oil-bearing material and ethanol in a mass ratio of 1:1.5-3.5, then stirring the mixture for 5-8 min, adding a composite surfactant formed by mixing polyglyceryl-10 palmitate and polyglyceryl-10 monolaurate in a mass ratio of 3-4:17-22, with the mass of the composite surfactant being 0.3-0.7% of the mass of the ethanol, stirring the mixture for 20-25 min, allowing the mixture to stand, and then performing solid-liquid separation to obtain an oil-ethanol mixture and ethanol-containing oil-bearing material dregs; a step of adding the dregs into a juicer, and squeezing the ethanol in the dregs out through extrusion by a pushing bar of the juicer to obtain oil-bearing material cake; and a step of allowing the oil-ethanol mixture to stand and layer, and separatingan oil layer through a l
