Technologies for extraction of oil from oilseeds and other plant

  • What are the methods used to extract essential oil from plants?
  • The methods used to extract essential oil from these plants are; steam distillation (SD), solvent-assisted extraction, hydro distillation (HD), ultrasonic-assisted extraction, supercritical fluid extraction and solvent-free microwave extraction (Belhachat et al., 2018). Oil extraction techniques are classified as shown in Fig. 1.
  • Why do we need improved cultivars for vegetable oil extraction?
  • Limited land availability and growing demands for vegetable oils call for the development of improved cultivars for harnessing higher yields as well as more efficient oil extraction technologies to augment oil recovery from different oilseed crops without compromising with the oil quality.
  • How is essential oil extracted?
  • In this technique, solvents are mixed with plants sample and then mixture is moderately heated. Essential oils are extracted by filtration and evaporation of solvents. Resinoid, aroma and essential oil were found in the filtrate. Resinoid is mixed with alcohol to extract essential oil followed by distillation at low temperature.
  • How essential oils are extracted by steam distillation?
  • This technique extracted 93% of essential oils, and other methods were used to extract the remaining 7% (Radwan et al., 2020). First step in steam distillation is cutting of fully grown aromatic plants. These plants are left in a field for several days for drying purposes. Plant ‘hay’ material is prepared by chopping plants.
