  • 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.
  • What are the different extraction methods for rapeseed oil?
  • T able 1. Comparative study of rapeseed oil extraction methods. T able 1. Cont. drying. treatment. industrial scale. color. taste and color. 2.1. Hexane Free Oil Extraction ]. Other methods were reviewed by removed by the solvent extraction, and even had a better taste and odor. However, these common extraction methods for rapeseed oil.
  • 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.
  • Can cold pressed rapeseed oil be used as functional oil?
  • Cold-pressed rapeseed oil can use as functional oil due to its health benefits. Rapeseed oil is the second most abundant produced edible oil in the world with low erucic acid and low glucosinolate. Thus, the quality of rapeseed oil had attracted global attention.
