  • What is conventional deodorization for refining vegetable oil?
  • Conventional deodorization for refining vegetable oil involves evaporating volatile molecules by applying high temperatures (240–260 °C) for 2–3 h. It inevitably leads to a degradation of the refined oil quality. The chief volatile compounds from the conventional deodorization process were hydrocarbons, which are not the odor source of the oil.
  • What is deodorization in edible oil refining?
  • In current edible oil refining, deodorization is also the process in which free (nonesterifed) fatty acids (in the case of physical refining) and volatile contaminants are stripped and unwanted color pigments are degraded (heat bleaching).
  • What is a deodorization step in a refining process?
  • These technologies are generally a succession of unit processes of degumming, neutralization, bleaching, and deodorization (Erickson, 1995). A deodorization step is essential at the end of the refining process to improve the quality and taste of vegetable oil by eliminating undesirable odors.
  • How can a deodorizer reduce thermal degradation?
  • This is especially required to minimize thermal degradation reactions (e.g. formation of trans fatty acids in soybean and canola oil, formation of glycidyl esters in palm oil). These negative thermal effects can be minimized by using packed columns or dual-temperature deodorizers (Fig. 9).
