Stability of pumpkin seed oil | Request PDF - ResearchGate

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.
