  • 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 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.
  • 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.
  • Where is rapeseed oil produced?
  • The oil is widely produced globally, with China, Canada, and India being the leading producers. The rapeseed oil manufacturing process results in by-products like rapeseed meal and press cake, which are utilized as animal feed, bioenergy, and biorefining sources.
  • Why are rapeseed polyphenols important?
  • Most of the rapeseed polyphenols were thermal and pressure sensitive compounds, thus, their content were strongly influenced by the rapeseed and rapeseed oil processing technologies, including the rapeseed pre-treatment, the rapeseed oil extraction and the oil refining processes.
  • What is rapeseed oil bearing material?
  • The rapeseed (Brassica napus L.) are the important oil bearing material worldwide, which contain wide variety of bioactive components with polyphenolic compounds considered the most typical.
