How to tell if canned nuts are bad
Smell
Rancid: like crayons, paint or old nuts.
Taste
Bitter or soapy aftertaste.
Texture
Sticky or gummy residue around the lid.
Colour
Darkened or cloudy where it should be clear.
Canned nuts past the expiration date
Unopened
FoodKeeper gives unopened canned nuts 1 year in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 4–6 months in the fridge or 2–9 months in the pantry from the day you open it.
How to keep canned nuts fresh longer
- Keep in a cool, dark place, tightly closed, away from heat.
- Refrigerating nuts, seeds and nut oils extends shelf life significantly.
- Smell before using; rancidity is a quality problem you can detect.
