  • Does extraction technology affect rapeseed oil functional quality?
  • Extraction technology can influence the vegetable oil functional quality. Polyphenols in rapeseed oil have been proved to be beneficial for cardiovascular health. In this study, we evaluated the effect of extraction methods on the functional quality of rapeseed oil from the perspective of phenolic compounds.
  • What is synchronous pressing and refining of rapeseed oil?
  • A new method for rapeseed oil preparation named synchronous pressing and refining after solid-phase preadsorption technology was investigated. Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering.
  • 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.
  • What is the best extraction method for rapeseed oil?
  • Taken together, hot pressing can be considered the best extraction method for rapeseed oil from the perspective of phenolic compounds.
  • What is rapeseed oil preparation technology?
  • The present rapeseed oil preparation technology universally used is prepressing and leaching technology. It is a long-term process with high energy consumption and a large discharge of three wastes (wastewater, waste organic solvent and residue).
  • How is rapeseed oil extracted?
  • There are several purely mechanical extraction methods: cold pressing, pressing after cooking and double pressing (cold pressing followed by heat conditioning and a second pressing). Their performance in terms of residual oil content in the meal ranges from 9.9 to 16.3%, 9.7 to 15.7% and 8.7 to 13.5% residual oil (rapeseed), respectively .
