  • 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.
  • What is a good refining method for rapeseed oil?
  • Silicon dioxide had the best refining effect, with dephosphorization and deacidification rates of 95% and 42%, respectively, when the dosage was 30 g/kg at a squeezing chamber temperature of 130 °C. At the same time, the L* value of rapeseed oil increased by 21%, and the a* value decreased by 59%.
  • 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 rapeseed adsorbents are extracted from crude oil?
  • Rapeseed and adsorbents were first mixed evenly to form premixes, and the product oils were then obtained by direct pressing and filtering. The phospholipid content, acid value, a* value, chlorophyll, carotene, polyphenol contents of crude oil increased, while L* and b* values decreased with increasing squeezing chamber temperature.
  • How does refining rapeseed oil affect oxidation stability?
  • Wu, Zhou, Wang, Wang, Yang, Ju and He studied the effects of refining on the physicochemical properties and oxidation stability of five varieties of rapeseed oil, and the results showed that the order of reducing the tocopherol content by different refining steps was deodorization >?bleaching >?neutralization >?degumming .
  • How rapeseed oil color change after refining?
  • Schematic diagram of the color change of rapeseed oils before and after refining . Generally, the process of industrial bleaching is to bleach crude oil at a high temperature for 20¨C40?min by using bleaching soil after activation.
