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.
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.
Are there phytosterols in pumpkin seed oil extracted by organic solvents?
Phytosterols in pumpkin seed oil extracted by organic solvents and supercritical CO 2 Eur. J. Lipid Sci. Technol., 114 ( 2012), pp. 1204 – 1211, 10.1002/ejlt.201200009 Supercritical CO 2 extraction of oil, carotenoids, squalene and sterols from lotus ( Nelumbo nucifera Gaertn) bee pollen
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.
