  • What is oilseed pretreatment?
  • Oilseed pretreatment usually means the working procedures of detaching the impurities out of the oil material to make the oilseeds in the best condition before pressing in order to extract the most oil out. It is the first and most vital step during the whole set of oil mill plant.
  • What are the unit operations for preparation of seeds for oil extraction?
  • Unit operations for preparation of seeds for oil extraction vary slightly depending on the physical properties and oil content, however, most oilseeds go through the process of selecting/cleaning, shelling and separating, crushing and flaking, roasting.

  • Does pulsed electric field increase oil yield in sunflower seeds?
  • There was an increase in oil yield by 9.1% in sunflower seeds when a pulsed electric field of 7 KV/cm, frequency of 15 Hz, the solvent content of 40% (wt.) and pulse width of 30 μs for 30 s was used, followed by extraction using Soxhlet apparatus (Shorstkii et al., 2015).
  • Why do Kalahari melon seeds have higher FFA and peroxide values?
  • The reason for the higher FFA and peroxide value in Kalahari melon seed oil from AEE than SE oil could be attributed to the lipase activity in the seeds at the time of initial heating in the AEE process (Nyam et al., 2009).
  • Does microwave pretreatment of canola seeds increase extraction efficiency?
  • Microwave in combination with pulsed electric field (MW-PEF) as pretreatment to canola seeds (Mohseni & Mirzaei, 2019), reported an increase in extraction efficiency with an increase in MW time (0–200 s), PEF intensity (0–50 KV/cm) and rotational speed of the screw (11–57 rpm).
  • Does ohmic pretreatment affect the colour of mustard oil?
  • Whereas mustard oil extracted from ohmic-heated mustard seeds had its L value (light to dark) range from 40.32 to 40.87 as against 40.71 of the control sample showing that ohmic pretreatment had negligible impact on the colour of the oil (Viswasrao et al., 2017).
