• 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.
  • Why is pumpkin oil better than pumpkin seeds?
