FAQ

  • Does rapeseed oil vary during refining process?
  • Information on the physicochemical variability in rapeseed oil from different varieties during each refining process is lacking. Our purpose was to investigate the physicochemical properties, micronutrients and oxidative stability of the oil extracted from the five varieties of rapeseeds during their different stages of refining process.
  • Does rapeseed oil have physicochemical properties and oxidative stability?
  • Although many researchers have investigated the physicochemical properties of rapeseed oil, there is still a lack of information on the physicochemical properties and oxidative stability as it relates to different rapeseed varieties during refining process.
  • What are rapeseed oil tocopherols?
  • They (α, γ, and δ) are potent natural antioxidants that can inhibit the deterioration of oils during storage and prolong the shelf life of edible oils . Fig 5 showed total and individual tocopherol contents of different rapeseed oil varieties at each step of refining process.
  • How much tocopherol is lost in rapeseed oil?
  • Previous study reported the greatest losses of total tocopherol content in oils could be induced by physical refining (deodorization), amounting approximately to 20.2–27.1% , and the deodorization step would cause 7–90% losses of tocopherols in rapeseed oils .
  • Why did rapeseed oil decrease -tocopherol?
  • The decrease of α-tocopherol, γ-tocopherol, δ-tocopherol and total tocopherols in different rapeseed oil varieties during the neutralization were from 6.21 to 10.01%, 8.71 to 14.52%, 13.70 to 29.12%, and 9.31 to 12.94%, respectively. The reduction might be due to the instability of tocols in the presence of air and alkali.
  • Is rapeseed oil a polyunsaturated fatty acid?
  • Rapeseed oil contains around 1.5–6% palmitic acid, around 0.5–3.1% stearic acid, around 28% oleic acid, around 11–23% linoleic acid, and around 5–13% linolenic acid. It is characterized by the ideal content of polyunsaturated fatty acid due to the ratio (2:1) of linoleic acid (n-6) and linolenic acid (n-3) fatty acid.
