The invention discloses a refining technology for reducing chloropropanol ester in camellia seed oil. The refining technology comprises the following steps: 1) filtering crude oil and removing mechanical impurities; then pre-heating and adding water to carry out hydration; standing and precipitating; separating to obtain oil and hydrated oil; then taking the hydrated oil and adding water; then adding phosphoric acid; finally, carrying out neutralization by utilizing liquid sodium silicate with the concentration of 0.5 percent; standing and precipitating; separating oil soap; 2) putting the crude oil into a de-coloring pot and de-coloring according to a conventional technology; 3) carrying out deacidification and deodorization; heating in molecular distillation equipment under a low vacuumcondition, and discharging free fatty acid in oil of a fraction and a low molecular weight odor substance along steam; 4) carrying out winterization and dewaxing to obtain a finished product. By adopting the refining technology disclosed by the invention, the content of chloropropanol ester compounds in the camellia seed oil can be remarkably reduced and potential hazards of oil products to humanbodies are prevented; the refining technology also can ensure that the refined camellia seed oil reaches national hygienic standards and the safety level of the camellia seed oil is improved; guarantees are provided for safe production of the camellia seed oil and guarantees are provided for health of consumers.
