Expiration & Storage Tips
When does pumpkin seed expire?
Unopened store-bought pumpkin seeds can last about 1-2 years past the 'Best By' date printed on the package if stored properly. Once opened, however, they should be consumed within 3 months for the best quality, and can still be safe to eat for up to 6 months when stored correctly. Freezing is also a great option for longer-term storage. Frozen pumpkin seeds are safe to consume indefinitely, but best quality is maintained for about a year.
How do you tell if pumpkin seed is bad?
Pumpkin seeds have gone off on if they exhibit any changes in their color, texture, or smell. They might take on a yellow or dark discoloration, become slimy or moldy, or emit a rancid or off smell. If they've been stored for a long time, they may also have lost their crunch and become stale. Non-edible mold can also grow on pumpkin seeds that have been kept in a damp environment. It's important to toss the seeds if any of these signs of spoiling are detected.
Tips for storing pumpkin seed to extend shelf life
• Keep the pumpkin seeds in a cool, dark, and dry place. A pantry or a cupboard away from the stove, oven, and sink is often a good spot.
• Transfer opened seeds to a airtight container or resealable plastic bag to reduce exposure to air, moisture, and pests.
• Store the seeds in the refrigerator if possible, as this can prolong their freshness.
• To store pumpkin seeds for long-term use, freeze them. Pack the seeds in a freezer-safe airtight container or bag. No need to thaw them before use - just take out as many as you need.
