FAQ

  • QHow to prepare rapeseed oil?
    AAt present, the most frequently utilized methods for the preparation of rapeseed oil are either mechanical pressing or solvent extraction (Ye & Liu 2023 ), such as hexane extraction (HE), which has the advantages of a large processing capacity and low production cost ( Guo, Wan & Huang 2019 ).
  • QHow are rapeseed seeds extracted?
    AThe 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%.
  • QAre you manufacturer or trading company?
    AWe are manufacturer.
  • QHow rapeseed oil is extracted by cold pressing compared to Soxhlet Method?
    AThe 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.
  • QHow to maximize rapeseed oil yield?
    AIn 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.
  • QHow much rapeseed oil can be extracted by cold pressing?
    AA 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.
  • QDoes cold screw pressing affect the fatty acid profile of rapeseed oil?
    AHowever, 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.
