Download Citation | Physical refining of edible oils | Crude oils obtained by oilseed processing have to be refined before the consumption in order to Among other methods of physical refining the application of selective membranes is promising. A Versatile Apparatus for the Bench Scale Bleaching and Deodorisation of Vegetable Oils During this degumming process, some NaOH can be added as well, to increase the hydratability of the phospholipids (Nilsson-Johansson et al.
