After rapeseed is pressed by rapeseed oil press machine, the oil obtained contains a strong flavor, but in order to make the oil last longer and have better color and oil quality, rapeseed oil refining machine is needed. Many people think that the flavor of rapeseed oil will disappear after refining process. Is it true?

The answer is that it will not disappear, but will be more pure and lasting. Because the aroma of rapeseed oil is not only the fruity aroma in its own cell wall, but also the reaction aroma produced by hydroxyl and amino groups at high temperature. The higher the processing temperature, the stronger the aroma, but the pigment ions will increase and the color will become darker.

Rapeseed oil refining machine includes degumming, deacidification, dehydration, decolorization and deodorization. Through these five steps, the flavor will be greatly reduced, but we can carry out a semi-refining process (only degumming, deacidification and dehydration) to remove water, peroxide and colloidal impurities in the oil. This refined oil not only has a long storage time and good oil quality, but also removes the flavor produced by the reaction, making the oil taste more pure and pure.
