  • 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.
  • 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.
  • Does sunflower oil retain more tocopherols in chemical refining process?
  • In chemical refining process, sunflower oil retained more tocopherols compared to the physical refining method. However chemical refining is considered less efficient due to saponification of neutral oil. 1. Introduction Vegetable oils are obtained through two primary methods: pressing and extraction.
  • 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.
  • What is vegetable oil refining?
  • Refining of edible oil is a process where free fatty acids are volatilized, condensed, and recovered simultaneously with vacuum decoloring operation. However, processes in vegetable oil refining, such as filter backwash, acidification of soap-stock, and washing of equipment, produce big amounts of wastewaters .
  • What is a sunflower oil refining unit?
  • An experimental oil refining unit has been developed for minimal refining of sunflower oil. The unit consists of (i) one open mild steel tank with conical bottom for degumming/neutralization, (ii) one closed oval tank for vacuum drying/bleaching and (iii) one filter for filtration of oil.
