• How is crude pressed sunflower oil refined?
  • Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared. The phosphorous content, FFA content, peroxide value and wax content decreased during the refining process.
  • Can sunflower oil be refined?
  • An experimental oil refining unit has been developed and tested for refining of sunflower oil. Crude pressed sunflower oil obtained from a local oil mill was refined using chemical method by degumming, neutralization, bleaching and dewaxing. The quality and composition of crude and refined oil were compared.
  • What are the advantages of Physical refining of sunflower oil?
  • Physical refining has several advantages compared to the classical chemical one. This process is more economical (improved yield, lower investment cost, less chemicals used) environmental friendly process (no soapstock to be treated, splitted) but more sensitive to the crude oil quality. Physical refining of sunflower oil is discussed in details.
  • Can Egypt produce sunflower oil self-sufficiency?
  • Sunflower crop was introduced in Egypt in 1987, and the oil content of its seed ranges between 39 and 46% (The Arab league for Nutrition Industries, 2007 ). The Minister of Supply and Internal Trade indicates that Egypt will accomplish sunflower oil creation self-sufficiency by nurturing lands and refining edible oils in bordering Sudan.
  • What is a large capacity sunflower oil refining line?
  • Huge capacity sunflower oil physical refining lines are successfully operating in different countries using the developments of last decades resulting in better processes, more suitable adsorbent, high capacity equipment with really improved performance producing high quality refined sunflower oil in a more economic and environmental friendly way.
  • Why is crude sunflower oil difficult to refine?
  • Crude sunflower oil which has reached a certain level of oxidation, is difficult to refine. There are two main difficulties: – removal of non-hydratable phospholipids/iron; – and sometimes when the autooxidation has really gone too far fix colour formation, which is not removable by bleaching and/or heat bleaching.
