Tips for storage

Prevent rancidity - tips for using of the Styrian pumpkin seed oil P.G.I.

Oxygen, warmth and light stimulate the degradation of the unsaturated fats in pumpkin seed oil and cause the oil to quickly go rancid. This is why Styrian Pumpkin Seed Oil P.G.I. is stored in well sealed dark bottles. It is possible to store an unopened bottle for 9 - 12 months at room temperatures lower than 18 C (291 K, 64 F), but of course the shorter the storage time, the better and nuttier the flavour.

Opened bottles of pumpkin seed oil should be used within 6 - 12 weeks. As the oil is used, the ever increasing amount of air in the bottle is of ever increasing importance. The more air in the bottle, the more oxygen is available to oxidize the fatty acids in the remaining oil. It is possible that pumpkin seed oil can go rancid towards the end of a bottle; that the rest of the oil is not enjoyable anymore and that it ends up as waste oil. The best prevention is to buy a bottle fitted to your individual needs. That's how smaller bottles, of 250 ml or 500 ml, can ensure the quality and culinary delight last as long as possible !!!!!

It is also a good idea to wipe the drops of oil away from the bottle's neck after pouring, this residue oxidizes very quickly. This rancid oil residue can lend its rancid flavour to the next dish where Styrian Pumpkin Seed Oil P.G.I. is needed, though the oil in the bottle is actually still good.
