  • How is oil extracted from rapeseed?
  • Oil is extracted from rapeseed using either mechanical pressing or solvent extraction. Cold pressing preserves more nutrients and antioxidants but yields less oil. Solvent extraction is commonly used in large-scale production, providing a higher yield but requiring further purification. 2. Degumming and Refining
  • 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.
  • 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 to maximize rapeseed oil yield?
  • In the present study, the optimization aimed to maximize rapeseed oil yield by selecting the suitable screw pressing conditions, i.e., the best nozzle diameter, press head temperature, and screw frequency in the applied experimental domain, by employing the desirability function 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.
  • How are rapeseed seeds extracted?
  • The rapeseeds were milled using a laboratory mill (A11 basic, IKA, Germany) and sieved into 1 mm fractions. The obtained fraction of seed material (about 20 g) was treated with petroleum ether (b.p. 60–90 °C) within 7 h. The extraction of the seed oil was done in triplicate. The oil content of the seeds was 40.9 ± 0.1%.
