  • What is the quality of oil obtained from pumpkin by-products?
  • Conclusions The enhancement of the quality of oil obtained from pumpkin by-products using a structured bed of pumpkin seeds and peel as the source material and compressed propane as the extraction solvent is reported herein. Oil yields of (12.56 to 15.36) % were achieved.
  • How are oil bodies extracted from pumpkin seeds?
  • Oil bodies from pumpkin seeds were extracted, isolated, characterised using optical microscopy, zeta potential and particle size distribution obtained. During microscopic analysis, the oil bodies were more intact and in an integrated form at the time of extraction but were ruptured with time.
  • How to optimize the extraction process of pumpkin seeds oil?
  • Owing to optimize the process, the following parameters were considered: extraction time, extraction temperature, and particle size. Soxhlet setup was used for extraction of pumpkin seeds oils. Using the combinations of chosen parameters, as provided in TableIII, experiments were carried out.
  • Which solvent is used to extract oil from a structured bed?
  • In this context, pressurized propane was used, under different temperature and pressure conditions, as the solvent in the extraction of oil from a structured bed composed of pumpkin seeds and peel.
  • Does a pumpkin peel extractor produce a low yield?
  • Low yields were observed when only the peel was used in the extractor (3.44%). The pumpkin peel is rich in tocopherols and β-carotene, but it has a lipid content approximately 98.34% lower when compared to that of the seeds . Table 1. Experimental conditions and results for oil yield obtained from pumpkin by-products using compressed propane.
  • Can pumpkin seed oil be extracted using pressurized propane?
  • Reports on pumpkin seed oil extraction using pressurized propane could not be found in the literature, however, in studies using pressurized extraction with carbon dioxide oil yields of 21.47% and 50% were obtained by Wang et al. and Salgin and Korkmaz , respectively.
