• 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).
  • How does a deodorizer work?
  • The oil then proceeds to a final heater where it is brought up to the exact temperature required for deodorization, normally using high-pressure steam. When the oil has reached the designated temperature, it is fed to the deodorization column, which is the main component used for deodorizing edible fats and oils.
  • What is deodorization process?
  • 2. Deodorization principle Deodorization is actually a stripping process in which a given amount of a stripping agent (usually steam) is passed for a given period of time through hot oil at a low pressure. Hence, it is mainly a physical process in which various volatile components are removed.
  • How does Alfa Laval deodorization work?
  • Modular, easy-to-customize Alfa Laval deodorization systems optimize the stripping and retention sections to your exact processing requirements¡ªfrom seed oil deodorization and tropical oil deacidification to oils with low levels of GEs and toxic trace elements.
  • What is conventional deodorization for refining vegetable oil?
  • Conventional deodorization for refining vegetable oil involves evaporating volatile molecules by applying high temperatures (240¨C260 ¡ãC) for 2¨C3 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.
  • How does a deodorization column work?
  • Pre-stripping and retention When the oil has reached the designated temperature, in range of 220-260¡ãC depending on the processed oil, it is fed to the deodorization column, the main component used for deodorizing edible fats and oils. The column can consist of a stripping section and a retention section.
