• How to evaluate the oil content of Jatropha seed?
  • As a result, it was indispensable to evaluate the oil content of Jatropha seed either through blocking variation in extraction methods or extraction parameters. For instance, the oil content of Jatropha collected across nine regions was estimated using a conventional oil extraction method [ 80 ].
  • Is Jatropha a good energy crop?
  • Jatropha has been identified as a promising energy crop with good quality oil and lower processing cost than other feedstocks [ 33 ]. The plant has higher adaptability in moistures stress and degraded land with higher seed oil content.
  • How to extract oil from Jatropha seeds/kernels?
  • Solvent/chemical extraction, mechanical pressing, enzymatic extraction, and supercritical fluid extraction methods have been the dominant methods for expelling the oils from Jatropha seeds/kernels [ 1, 93 ].
  • Can Jatropha curcas grow oilseed?
  • Francis et al. (Francis et al., 2005) reported that Jatropha Curcas thrives on underutilised locations with little water and poor soil, according to reports, and it may yield oilseed as early as the first year of growth, although on a small scale.
  • Do Jatropha seeds have low oil content?
  • Ethiopia’s origin Jatropha seeds showed relatively lower oil content as compared to other origins. Fig. 2. Oil content of Jatropha oil detected by near-infrared spectroscopy content. Jatropha seed’s oil content was changed considerably between different agroecological zones of single growing regions.
  • Why do we need to prepare Jatropha seeds before oil extraction?
  • High production of biodiesel is required to cope with the depletion of current energy sources. Hence, a large amount of Jatropha seeds need to be prepared prior to the oil extraction process in order to meet the demand.
