✦ Synopsis

Classical alkaline refining of liquid vegetable oils removes free fatty acids, phospholipids, metals, oxidized components and (off-)flavours by a number of stages. This process is relatively expensive and produces effluent. Physical refining avoids the alkaline neutralisation step and therefore phospholipids and metals have to be removed by other means, e.g. by adsorbents. The principles of this adsorption are discussed and it is shown that physical refining applying silica to remove phospholipids is technically feasible, even when water-degummed oils are treated.

Samples of crude, neutralized; bleached and deodorized cotton seed oil (Egypt), safilower oil (Iraq) and sunflower oil (Iraq) were analyzed for their total tocopherol and their contents of iron and copper, The stability of oils under investigation was measured by the Active Oxygen Method. The crude
