• What is edible oil refining?
  • Edible oil refining is a set of processes or treatments necessary to turn vegetable raw oil into edible oil .
  • 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.
  • 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.
  • Why is oil refining important?
  • In addition, the refining process of oil is also continuously optimized to meet the requirements of consumers for higher levels of oil quality . It is worth noting that in order to increase their profits, many businesses adulterate vegetable edible oils, which greatly harms the health of consumers .
  • 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 .
  • What is the industrial processing of vegetable oils?
  • The industrial processing of vegetable oils has become increasingly standardized based on national or international standards, and high-capacity production of extraction and refining has been realized .
