Sesame seeds past the expiration date

Best-by and sell-by

FoodKeeper gives unopened sesame seeds 5 years 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.

Past the date

Sesame seeds past their best-by date are usually safe if stored well; check smell, look and taste before using.

How to keep sesame seeds 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.
