  • 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.
  • How rapeseed oil is extracted by cold pressing compared to Soxhlet Method?
  • The crude oil extraction degree achieved by cold pressing was 60.8% compared to the Soxhlet method. The rapeseed oil contains predominantly oleic, linoleic, linolenic, and palmitic acids, agreeing with other reported rapeseed oils.
  • How much rapeseed oil can be extracted by cold pressing?
  • A nozzle diameter of 10 mm, a screw frequency of 50 Hz, and a press head temperature of 80 °C ensured the maximum pressed rapeseed oil yield of 26.65% within the applied experimental domain. The crude oil extraction degree achieved by cold pressing was 60.8% of the rapeseed oil yield obtained by the Soxhlet method.
  • Does cold screw pressing affect the fatty acid profile of rapeseed oil?
  • However, the recovery methods used (cold screw pressing, hydraulic pressing, and Soxhlet extraction using petroleum ether) and the operating conditions of cold screw pressing in the applied ranges did not affect the fatty acid profile of the rapeseed oil.
  • What are rapeseed oil tocopherols?
  • They (¦Á, ¦Ã, and ¦Ä) are potent natural antioxidants that can inhibit the deterioration of oils during storage and prolong the shelf life of edible oils [ 29 ]. Fig 5 showed total and individual tocopherol contents of different rapeseed oil varieties at each step of refining process.
