  • What are the 4 stages of canola oil refining?
  • Canola oil refining consists of four main stages: degumming, neutralization, bleaching, and deodorization. Table 4 shows the composition of crude and refined, bleached, and deodorized (RBD) canola oil. Degumming is the first stage in edible oil refining.
  • Does canola oil need to be refined?
  • This canola oil can proceed directly to bleaching in a process that is referred to as ¡°physical refining.¡± Once-refined oils also do not require further alkali refining. In traditional alkali refining, the crude degummed oil is heated to 50¨C60°C, at which time 300¨C1000 ppm of phosphoric acid is injected into the oil and mixed vigorously.
  • Why is crude canola oil refined?
  • Crude canola oil is refined in order to remove undesirable minor compounds that make this oil unusable in food products. However, refining can also cause the removal of desirable health-promoting minor components from the oil.
  • What are the undesirable components of crude canola oil?
  • In addition to the above-mentioned desirable minor components, crude canola oil contains many undesirable minor components such as free fatty acids, phospholipids, chlorophyll, trace metals, waxes, oxidation products and pesticide residues. These are generally removed during refining.
  • Does canola oil production contribute to environmental impacts?
  • Preliminary results indicate that the greatest consumption of fossil fuels that occurs in the agricultural phase, as well as the use of chemical products, promotes potential environmental impacts, but the process that most contribute to the emissions is the canola oil production.
