Oilseed Enzymatic Pretreatment for Efficient Oil Recovery

Novel seeds pretreatment techniques: effect on oil

  • How does a pretreatment unit help in oil extraction in Jatropha seeds?
  • The pretreatment unit alone decreases an amount of energy in Jatropha seeds before actual oil extraction which helps in oil extraction in Jatropha seeds by 24% of the total internal energy of solvent extraction processes and 66% for mechanical extraction.
  • Which pretreatment is used in oil extraction for seeds?
  • Microwave and ultrasonic pretreatments are the most commonly used pretreatments in oil extraction for seeds. The main experiment was carried out in National Research Centre, Giza, Egypt. During summer season of 2021. Egyptian castor seeds were obtained from a privet farm in Sinai Governorate.
  • Does pretreatment improve oil yield?
  • Oil yield ranged from 32.67 to 37.41% compared to 13.29 to 39.83% in literature. The time required for extraction was ranged from 1.77 to 2.00 and 1.79 to 2.21 min for microwave and ultrasonic pretreatments, respectively. The pretreatment improved properties of the extracted oil. Industries are consuming energy less than that of buildings.
  • What are the optimum conditions for oil extraction by screw press?
  • The results indicate that the optimum conditions oil extraction by screw press were 200 °C extraction temperature and 60 rpm screw speed. It could be seen that the extraction oil yield, extraction energy requirements and extraction time were 35.59%, 18.68 and 1.86 min, respectively.
