• What is edible oil refining?
  • Edible oil refining is the process of converting raw vegetable oil into edible oil. Raw vegetable oils, whether obtained through pressing or solvent extraction, contain unwanted components such as free fatty acids, phospholipids, and others, which cause undesirable flavors, odors, and appearances.
  • How does edible oil refining reduce production costs?
  • In edible oil refining, the continuous effort to reduce overall production costs is mainly achieved by increasing plant capacities, installation of mono feedstock plants, and increasing the degree of automation. Over the years, more energy-efficient processes and technologies, resulting in a higher refined oil yield, have gradually been introduced.
  • How does Alfa Laval refine crude oil into edible oil?
  • Refining crude oil into edible oil requires deep process knowledge¡ªfrom degumming, neutralization and dewaxing through to bleaching, deodorizing and GE and 3-MCPD mitigation. Edible oil producers worldwide rely on Alfa Laval know-how to remove impurities and volatile components and optimize refining processes.
  • Why is precision important in edible oil refining?
  • In the edible oil refining industry, precision is paramount. Just as a maestro has an orchestra of instruments, this process utilizes a suite of specialized machines, each playing its vital role to guarantee that the resulting oil is of premium quality.
  • How does refining affect the stability of refined edible oils?
  • This directly influences the stability of refined edible oils. Efficient refining processes should be developed for crude oils to remove undesirable compounds while doing the least possible damage to the interesting components at the same time and not generating higher levels of unwanted compounds.
  • Is Physical refining better than chemical refining for vegetable oil?
  • The effects of process conditions on standard quality parameters and the nutritional quality of the oil are well documented in the literature [5, 19, 71, 72]. In conclusion, physical refining offers great several advantages over chemical refining for vegetable oils (Table 2).
