The developed combined degumming and dewaxing process for the winterization (dewaxing) of sunflower oil is a high efficient refining step to remove phosphatides (gums) as well as waxes. This presentation shows the classical process steps, degumming and winterization and the combined process. The comparison of the two processes shows the advantages of the combined process.
