  • 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 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.
  • What is rapeseed oil preparation?
  • The typical industrial processing technology for the rapeseed oil preparation. The common processes for rapeseed oil preparation include rapeseeds pretreatment, rapeseed oil extraction, and refining processes.
  • How rapeseed oil is extracted?
  • The crushing and cooking of the rapeseeds are the important steps in order to obtain optimal conditions of the raw rapeseed materials for the subsequent oil extraction. There are different methods for the extraction of rapeseed oil from the rapeseeds, which typically include mechanical pressing, solvent extraction and AEE.
  • Are there competing interests in rapeseed oil?
  • Competing interests: The authors have declared that no competing interests exist. Rapeseed oil is a major source of vegetable oil in the world. Its production is estimated at 27.71 million metric tons, the third just behind palm and soybean oil, supporting the 2018 official data of United States Department of Agriculture.
  • Does refining rapeseed oil reduce phenolic content?
  • It was suggested that there was a remarkable reduction in total phenol content of the rapeseed oils after the whole refining process, i.e. from 4.83 to 6.19 mg GAE/100 g in the crude oil to 1.35¨C2.45 mg GAE/100 g in the refined oil. Moreover, the changes in the rapeseed phenolic content in different refining process were also different.
