Refining method of rapeseed oil

The invention discloses a refining method of rapeseed oil. The refining method comprises the following steps: step1, pre-treating: putting the rapeseed oil into an environment with the temperature of1 to 3 DEG C and standing for 45 to 55min; then carrying out microwave treatment and filtering to remove impurities, so as to obtain a substance A; step 2, degumming: raising the temperature of the substance A obtained by step 1 to 25 to 35 DEG C under the conditions that the stirring speed is 65 to 75r/min and the stirring time is 35 to 45min; then adding tartaric acid. According to the refiningmethod of the rapeseed oil, disclosed by the invention, an alkali washing manner is not adopted and oil consumption is less, so that the economic cost is reduced; in a degumming process, soluble impurities can be completely removed; meanwhile, the removing effect of colloids including phospholipid and the like is good and the refining method has relatively high utilization value and a good application prospect. 本发明公开了种菜籽油精
