  • What is the difference between ultrasound-assisted extraction and ohmic heating?
  • Ultrasound-assisted extraction (UAE) produces higher oil yield with superior quality in less extraction time. Similarly, Microwave pretreatment increases oil yield with improved flavor (extracted oil has a roasted flavor). Ohmic heating has the advantage of increased oil yield with lesser oil degradation.
  • What is the consumption of edible oil in India?
  • The consumption of edible oil in India has grown around 17.5 million in 2012-13. And 70% of the total groundnut produced is used for oil production. The groundnut oil is traditionally used as edible oil and demand is high. The demand of groundnut oil is having around 7% of annual growth rate.
  • Why is preserving edible oil important?
  • The variety of lipophilic substances present in edible oils is susceptible to oxidative reactions that result in the degradation of organic molecules. Hence, preserving the oil's nutritional and sensory quality is vital by employing pretreatment and refining methods.
  • What is an edible oil refinery unit?
  • An edible oil refinery unit is a vital component of a well-integrated complex that also includes an oil crushing unit, solvent extraction unit, vanaspati ghee manufacturing unit, and a rice sheller.
  • What are the different methods of oil extraction?
  • Conventional methods of oil extraction include mechanical pressing and solvent extraction. For better results, novel pretreatment techniques are being employed, such as thermal (Microwave (MW) and Ohmic Heating (OH)) and non-thermal methods (Pulsed Electric Field (PEF), Enzymatic Treatment (ET), Ultrasound (US)).
  • How does solvent extraction work?
  • Solvent extraction works by grinding the seed and purging or washing it with a petroleum distillate. This process releases the oil from the seed. The solvent is then removed by heating the oil in a sealed chamber. Finally, the oil is further heated to refine the solvent.
