  • What is the process of vegetable oil refining?
  • Full processing flow chart for a general vegetable oil refining process. Physical refining or refining by bleaching and distillation phases follows the same steps as chemical refining except that there is no neutralization step. Chemical refining removes FFA by neutralization with NaOH and is developed under vacuum with steam injection.‌
  • What are the 4 steps in oil refining?
  • The oil refining process has four main steps: degumming, deacidification (neutralization), bleaching, and deodorization. For the refining of crude vegetable oils, there are two main routes: the chemical and the physical refining. Some by-products of low commercial value are obtained through these refining processes.‌
  • Why is refining important?
  • In general, refining is a necessary process to ensure the quality of edible oils. It is very important to remove unnecessary components while retaining the important components of the oils. However, the refining process may cause oxidation of the oils and produce unfavourable degradation products, which may affect the quality of the oils.‌
  • What are the by-products of oil refining?
  • Important amounts of by-products such as soapstock, deodorizer fatty acid distillates, and acid oil are produced from the oil refining processes (Piloto-Rodriguez et al., 2014).‌
  • What is the last step of refining oil?
  • The last step of refining is deodorization. This procedure removes the odour, harmful volatile substances and pesticide residues from oils . Vacuum steam distillation deodorization is the most widely used method.‌
  • What based transesterification process is used in oil refining & biodiesel?
  • Most oil refining and biodiesel plants use the conventional NaOH/CH 3 ONa and/or H 2 SO 4- based transesterification processes (Díaz et al., 2021, Piloto, 2010). Esterification is applied when the FFA content in the oil is higher than 2%.
