  • How to extract bioactive compounds from palm kernel cake?
  • In this study, the extraction of oil and bioactive compounds from palm kernel cake (PKC), a byproduct of the palm oil mill, was investigated using Soxhlet extraction (SE), microwave-assisted extraction (MAE), and room-temperature liquid extraction (RTLE) using isopropanol as a solvent.
  • Can isopropanol extract oil from palm kernel cake?
  • Isopropanol was a potential solvent for extracting oil from palm kernel cake. Using SE at 150 °C, the energy input was relatively high at 4.68 kW h/g oil. Using MAE at 150 °C, the energy input was reduced to 1.52 kW h/g oil. Using MAE, defatted PKC had the fat content around 0.25%.
  • What is palm kernel oil extraction?
  • A food grade solvent known as hexane is used to extract the remaining 5% – 6% of residual crude palm oil (CPO) available in palm-pressed fibre, thereby enhancing oil extraction rate (OER) by 0.5%. Palm Kernel Oil Extraction (PKOE) Plant, is designed to extract the oil from kernel cake by means of solvent. This shall extract an additional 3% PKO.
  • Does solvent extraction of palm kernel oil consume more energy?
  • When compared with the mechanical oil extraction from palm kernels by screw pressing that required about 1.3 × 10 −3 kW h/g oil ( Ezeoha et al., 2017 ), solvent extraction of the residual oil from PKC tended to consume more energy. Energy expenditure was then considered to assess the different extraction methods.
  • What is palm fibre oil extraction plant?
  • Palm Fibre Oil Extraction Plant, a plant designed and equipped to extract the residual oil from palm-pressed fibre by means of solvent. A food grade solvent known as hexane is used to extract the remaining 5% – 6% of residual crude palm oil (CPO) available in palm-pressed fibre, thereby enhancing oil extraction rate (OER) by 0.5%.
  • Which products are obtained from the solvent extraction of PKC?
  • In this study, three valuable products, such as palm kernel oil, defatted PKC, and lignin derivatives, were obtained from the solvent extraction of PKC using isopropanol as the solvent. A distinct property of the extracted oil was that it contained valuable oil-soluble compounds, such as aromatic and phenolic compounds, and squalene.
