• What is vegetable oil refining?
  • As vegetable oil is an important component of the human diet, the source and the processing play an important role in consumer acceptability. To remove impurities that affect the color, palatability, stability, and safety of oil, crude vegetable oil must be refined. This review highlights the processes and steps used in vegetable oil refining.
  • 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.
  • 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 refining edible oil important?
  • Refining of edible oil by chemical or physical processes aims towards removing the undesirable impurities that affect oil quality and stability. Understanding the chemical nature of oil and associated impurities is important to designing refining steps.
  • Why do oil processors need a ‘next-generation’ refining process?
  • The growing importance of the (nutritional) oil quality and the sustainability aspect of the refining process itself are new challenges for oil processors. To reach these new objectives, ¡°next-generation¡± oil refining process technologies have to be developed and implemented.
  • What are crude vegetable oils & fats?
  • Crude vegetable oils and fats are mainly triacylglycerols (around 95%) along with impurities and variable amounts of other minor constituents. To ensure the oils are safe for human consumption, the crude oils are subjected to several purification steps, known as refining process.
