The invention discloses a method for removing a plasticizer in camellia oleosa seed oil. The method comprises the following steps: degumming crude camellia oleosa seed oil, washing with water, drying, filtering, deodorizing, finely filtering, and finely filtering to obtain finished oil. The deodorizing comprises the following steps: (1) deodorizing in a first-section main tower: introducing saturated water vapor after the oil temperature in the first-section main tower reaches 180-200 DEG C under the condition that the vacuum degree is less than or equal to-0.1 MPa, and circulating for 60-70 minutes; (2) deodorizing in a second-section main tower: under the condition that the vacuum degree is less than or equal to-0.1 MPa, controlling the oil temperature of the second-section main tower at 260-270 DEG C, introducing saturated water vapor, circulating for 80-100 minutes, and uniformly feeding oil into the first-section main tower at the same time; and (3) deodorizing in a third-section main tower: feeding the
