The invention discloses a method for producing low-temperature cold-pressed and refined tea seed oil, and belongs to the technical field of deep processing of agricultural products. The method for producing the cold-pressed and refined tea seed oil comprises the following main processes of: performing low-temperature storage on screened tea seeds, cleaning, grading, shelling, separating, drying, crushing, pressing at a low temperature, filtering, degumming, decolorizing, deodorizing, winterizing, and packing finished refined oil. By the new technology of low-temperature cold pressing and refining, overheating and excessive chemical treatment of the oil in the conventional processing are avoided, meanwhile, the residue of harmful substances produced in the conventional high-temperature processing is effectively reduced at the same time, the production cost is remarkably reduced, the purely natural property of the oil is kept, and physiological active substances in the oil are kept as much as possible. The tea oil produced by the method is light in color, low in acid value and peroxide value, low in phosphorus content, fragrant and rich in nutrition, and has a long storage period; and a feasible new path is provided for deep processing and utilization of the tea seed oil.
