  • How to extract oil from Niger seeds?
  • The study examined oil extraction from Niger seeds using microwave irradiation and pulsed electric fields (PEF) as pretreatments, followed by screw pressing. Optimal conditions were 156.23 s microwave time, 1.18 kV/cm PEF intensity, and 20 rpm press speed.‌
  • How much oil is extracted from dried leaves?
  • Researchers found that the extraction process produced oil ranging from 6.35 % to 8.04 % (w/w) of oil yield from dried leaves. The key technical elements influencing the extraction rate were temperature and .‌
  • How long does it take to extract oil?
  • The extraction duration (5–30 min), temperature (30 °C), and liquid–solid ratio (5–20 mL/g) were optimized using RSM. The results showed that 26.3 min extraction time and a 17.8 mL/g liquid-to-solid ratio produced the highest oil extraction yield (53.101 %) .‌
  • How is essential oil extracted from Citrus hystrix leaves?
  • Using subcritical water extraction (SWE), essential oil (EO) has been effectively extracted from Citrus hystrix leaves. Oil yield has been evaluated for varied particle size (0.5–1 mm), sample-to-solvent ratio (0.025–0.175 g/mL), extraction temperature (140–180 °C), and extraction duration (20–40 min).‌
  • How are Algerian Inula viscosa leaves extracted?
  • Additionally, in a study on green extraction methods, Algerian Inula Viscosa leaves were extracted using supercritical carbon dioxide (SC- CO 2) . This study yielded promising results, with dried leaf yields ranging from 63.5 to 80.4 g/kg. Temperature had a more modest influence on yield than pressure.‌
  • Does PEF technology affect the yield and quality of oil extraction?
  • The impact of PEF technology on the yield and quality of oil extraction is clarified by significant findings from assessments carried out at the industrial and pilot stages. The researchers used PEF as a pre-treatment method to extract essential oil from many sources. The results showed yield of essential oil varies with PEF voltage .
