  • What is rapeseed oil refining process?
  • Towards this, the crude rapeseed oil needs refining treatments to remove undesirable ingredients and produce higher quality oils [ 5 ¨C 7 ]. Traditional rapeseed oil refining processes generally involve four successive operations: neutralization, degumming, bleaching and deodorization.
  • Does refining rapeseed oil protect against oxidation?
  • The refining process removes the undesirable components, which extends the shelf life of refined rapeseed oil. However, the high level of bioactive compounds in the CPRO could protect the oil against oxidation. McDowell et al. (2017a) showed the CPRO was more stable under heat stress than refined rapeseed oil.
  • Does rapeseed oil differ after refining?
  • Differences were considered statistically significant at P< 0.05. The AV, PV, p -AV of the rapeseed oil in varieties after each refining process are shown in Fig 1. The AV of five different kinds of crude rapeseed oils were from 2.15 to 3.59 mg KOH/g and decreased significantly after neutralization, ranging from 0.29 to 0.45 mg KOH/g.
  • 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¨C27.1% [ 32 ], and the deodorization step would cause 7¨C90% losses of tocopherols in rapeseed oils [ 33 ].
  • What is synchronous pressing and refining of rapeseed oil?
  • A new method for rapeseed oil preparation named synchronous pressing and refining after solid-phase preadsorption technology was investigated. Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering.
  • 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.
