How to store sunflower oil

How to tell sunflower oil has gone bad

General signs for shelf stable foods, the group USDA lists sunflower oil under.

• Crackers or cereal that have gone soft or stale, not crisp
• Rancid, paint-like smell from nuts, oils or nut butters
• Small insects or webbing inside a box or bag
• Spices that have lost their smell and colour
• Fermented or boozy smell from honey that has picked up moisture

More on shelf stable foods. The times above are quality guidelines, not safety limits; food that shows these signs goes out regardless of the date.

Storage habits that make the difference

Store dry pantry staples in a cool, dry cupboard away from the stove and direct sunlight, ideally in airtight containers once opened. Reseal cracker and cereal bags tightly with a clip or transfer them to a container to keep them crisp. Label opened jars with the date so older ones get used first.
