  • Does microwave pre-treatment of rapeseed increase oil extraction yield?
  • Wroniak et al. (2016) reported the microwave pre-treatment of rapeseeds for 3 min would help to increase the oil extraction yield up to 64.5% with the rapeseeds presented 9% of moisture content. Microwave pre-treatment helps to reduce the moisture content of rapeseed, which affected the oil extraction yield from the seeds.
  • What is cold pressed rapeseed oil?
  • Cold-pressed rapeseed oil (CPRO) is a high-quality edible oil which can be used at high-temperature cooking and unheated in salad dressings. CPRO is obtained by crushing the rapeseeds at a constant low temperature. The CPRO obtained has a deep yellow color with a nutty taste ( McDowell, Elliott, & Koidis, 2017a ).
  • Is rapeseed defatting suitable for direct solvent extraction?
  • Due to its high oil content of up to 50 % in the seed, rapeseed defatting is not suitable for direct solvent extraction (Unger, 2011). Conventionally, oil extraction from rapeseed is achieved by screw-pressing, either by expeller pressing (full-pressing) or by pre-pressing of the seeds, followed by solvent extraction.
  • Can rapeseed be used in the production of oil and protein?
  • This review focuses on the use of rapeseed in the production of oil and protein. It covers the preparation of these products from the seeds, before their release in the market, and also discusses the utilization of natural unprocessed rapeseed.
  • Does rapeseed need a solvent or cold pressed extraction?
  • To meet the increasing oil demand, rapeseed production needs to increase. Currently, only solvent and cold-pressed extractions are used for large-scale production. While solvent extraction is cheaper, it may pose health risks.
  • Does rapeseed oil need more co-solvent than soybean oil?
  • Rapeseed oil system needs more co-solvent to keep one-phase than soybean oil system. In order to directly use rapeseed oil in diesel engines and reduce energy consumption in fuel preparation process, the density and viscosity of rapeseed oil have to be reduced and fuel properties can be adjusted by adding low-carbon alcohols (methanol/ethanol).
