The present invention discloses a process for improving the quality of heat-sensitive oils. For heat-sensitive oils rich in vitamin E and polyunsaturated fatty acids, a decolorization - medium and low temperature nitrogen and steam alternating stripping deodorization - enzymatic catalysis process is adopted to replace the traditional caustic refining - water washing - decolorization - high temperature steam deodorization process. In view of the problem that the acid value of oils is prone to increase during the decolorization and deodorization processes, the present invention proposes to carry out oil decolorization and deodorization before oil acid reduction. The increase in acid value caused during the oil decolorization and deodorization processes can bind fatty acids back to the glycerol backbone during the subsequent enzymatic catalysis process, thus effectively avoiding raw material loss. To reduce the impact of the conventional high temperature steam deodorization process on the functional substances in heat-sensitive oils, medium and low temperature nitrogen and steam are alternately used for stripping to remove the odor substances in the oils, and the quality of heat-sensitive oils is retained to the greatest extent. This process is applicable to the quality improvement of heat-sensitive functional oil raw materials rich in vitamin E, polyunsaturated fatty acids, etc., and has broad application prospects.
