Optimization of Pumpkin Oil Recovery by Using Aqueous Enzymatic Extraction and Comparison of the Quality of the Obtained of seeds, as well as to compare the quality of the obtained oil to the quality of cold-pressed pumpkin seed oil. Plant oil can be extracted by different methods, with prevailing techniques including non-polar solvent extraction or mechanical pressing (1). Residue in the tube was again centrifuged and the oil phase was withdrawn to obtain any residual oil.

In Austria pumpkins are grown primarily for the production of pumpkin seeds that can be used for eating or the production of salad oil. Pumpkin seed oil is dark green and its fatty acid composition consists typically of linoleic acid and oleic acid as the Most plant oils predominantly contain D5-sterols, whereas D7-sterols are tipical for only a few plant families, e.g. . the pumpkin oil quality and shelf life may have been due to the production process or the quality of the raw material.
