    Why does crude palm oil need to be refined?_Palm oil refining

    The main purposes of palm oil refining process is to purify the oil and remove impurities through degumming,deacidification, decolorization and deodorization process and then obtain pure and relatively non-impurities of high-quality edible oil. Next, I will briefly introduce the purpose of each stage of palm oil refining process.

    The importance of steam deodorization in edible oil refining

    Steam deodorization is one of the main steps in edible oil refining process. Generally speaking, there is still a little odor substance after degumming and deacidification steps, and residual white clay and solvent(n-hexane) smell after decolorization step. Steam deodorization aims to remove these undesirable smells in edible oil, so that it won't influence product oil quality.
