Is pumpkin seed oil vegetarian-compatible?

Watch for

The oxalate and nickel gap is the useful part. If you avoid pumpkin seeds because of kidney stones or a nickel-restricted diet, the oil is graded A on both where the seeds are graded E and C, since those compounds partition into the press cake and not the oil. That makes it a genuine way back to the flavour / Never cook with it. Pumpkin seed oil turns bitter and loses its colour and aroma with sustained heat, so it belongs on soup, salad, roasted vegetables or vanilla ice cream after cooking, not in the pan / Widely adulterated. Cheaper bottles are cut with sunflower or rapeseed oil and sold under the same name. Steirisches Kurbiskernol g.g.A. is the protected designation for the genuine Styrian article. A blended bottle means your diary entry is recording an oil you did not actually eat / It oxidises easily, which is why it ships in dark glass. Keep it cool and sealed and use it within months of opening; rancid pumpkin seed oil tastes sharp and acrid rather than nutty, and that is when people blame it for symptoms / The deep green comes from chlorophyll and carotenoids in the roasted seeds and is so intense the oil looks red in a thin film and green in the bottle. Colour is a freshness and authenticity cue, not a trigger
