• 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.
  • What is a Physical refining process?
  • In general, physical refining includes the following three main processing steps: Sometimes the dewaxing process is added for types of oils rich in waxes (e.g., fatty acids with low solubility in oils and high-melting esters of fatty alcohols), such as corn, rice bran, canola, and sunflower oils .
  • 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 oil is Deodorized for chemical refining?
  • Oils are deodorized under the conditions described above for chemical refining. The deodorization process has three main objectives: Removal of volatile components such as free fatty acids, different off-flavors, contaminants (pesticides, light polycyclic aromatic hydrocarbons, etc.).
  • What is crude oil refining?
  • Treatment that eliminates undesirable and toxic components in crude oils is known as ¡°refining¡± . Refining is practically mandatory for crude oils that cannot be consumed as virgin oils to provide a product with an attractive appearance, a neutral taste, and more resistance to oxidation.
  • Does refining affect the safety of refined oils?
  • These can directly influence the safety level of refined oils. Several studies were devoted to determining the effects of refining on the minor bioactive components such as sterols and tocopherols. Indeed, Verh¨¦ et al. , who found a sterols loss of 10¨C32% (physical refining) and 13¨C31% (chemical refining).
