Expeller pressing followed by solvent extraction of the cake is used for high-oil seeds because

  • A.Pressing removes the hulls
  • B.Solvent cannot dissolve the oil in such seeds
  • C.Pressing improves the oil's colour
  • D.Direct extraction of an oily seed is poor

Answer: D

A seed carrying forty per cent oil floods a solvent extractor and drains poorly, so most of the oil is pressed out first and only the remainder is extracted. Low-oil seeds such as soybean go straight to direct extraction.
