To provide a method for producing refined rapeseed oil of good flavor, the method is capable of suppressing the occurrence of content reduction of &agr-tocopherol, and can reduce the content of trans fatty acids. The manufacturing method of the present invention comprises a deodorization step for deodorizing the rapeseed oil. The manufacturing method is characterized in that the deodorization step includes a step of contacting water vapor with the rapeseed oil for 53 to 100 minutes at a temperature between 205 to 225 DEG C at a vacuum level of 300 to 800Pa. The amount of the water vapor may be 1.0 to 5.0 mass% with respect to the rapeseed oil. The aforementioned deodorization step can be carried out with a tray type deodorizer.本發明的問題在於提供一種風味良好的精製菜籽油的製造方法,該製造方法可抑制α-生育酚的含量發生降低的情況,且可降低反式脂肪酸的含量。本發明的製造方法,包含將菜籽油脫臭的脫臭步驟,該製造方法的特徵在於:上述脫臭步驟包含接觸步驟,該接觸步驟是於205~225℃的溫度條件,以300~800Pa的真空度,使菜籽油與水蒸氣接觸53~100分鐘。上述水蒸氣的量,相對於菜籽油,可為1.0~5.0質量%。上述脫臭步驟,能以托盤式脫臭裝置來進行。
