Abstract
Examining the oil output and the physiochemical effects of various extraction methods on pumpkin seeds was the primary goal of the research. We used n-hexan as a solvent in two separate oil extraction processes, cold press extraction (CPE) and soxhlet extraction (SE), and we choose pumpkin seeds for the job. In terms of oil yield, the SE technique achieved 64.07%, while the CPE approach came in at 36.33%. The physicochemical characteristics of the seed oils were discovered to be substantially affected by the oil extraction process, species, and the interaction between the two. Acidity, iodine, peroxide, saponification, density, refractive index, and viscosity were some of the physiochemical parameters measured for pumpkin oil. In terms of chemical tests, the Soxhlet extraction method outperformed CPE by 125, 3.02, and 1.03 iodine values, peroxide values, and acid values, respectively. On the other hand, CPE had a higher saponification number at 187.13, and SE had a lower one at 187.13. In terms of physical tests, the SE method outperformed CPE by 1.47, 0.916, and 76.4 viscosity, respectively. Both the oil yield and its physiochemical qualities were improved by the soxhlet extraction process, according to the results.
