Which of the following is NOT a seed preparation step?

  • A.Cooking
  • B.Deodorisation
  • C.Dehulling
  • D.Flaking

Answer: B

Correct answer: Deodorisation

Deodorisation is a refining step, and the last of them: it strips volatile flavour and odour compounds from the extracted oil by steam distillation under high vacuum.

The other three act on the seed before any oil has been obtained. Cooking thins the oil and sets the moisture, dehulling removes the hull, and flaking ruptures the cells. The division is worth holding onto - preparation makes the oil accessible, refining makes the recovered oil fit for use, and no step belongs to both.
