Signs sunflower oil has gone bad
- Rancid, paint-like, or bitter smell — the main sign oil has turned.
- Cloudiness or sediment (some is normal when cold; rancidity is not).
- Off or stale taste.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store sunflower oil
Keep oils in a cool, dark cupboard away from heat and light, which speed up rancidity. Seal tightly after use. Some delicate oils (flaxseed especially) keep longest in the fridge.
