Expiration & Storage Tips
When does pine nuts expire?
Unopened pine nuts in a vacuum-sealed package can stay fresh for up to 3 months at room temperature, and even longer in the fridge. Once opened, they'll last for about 1 - 2 weeks in your pantry, but can be preserved for up to 9 months if stored in the refrigerator. When frozen, pine nuts can keep their quality for about a year. After these timeframes, the taste might start to change, but it won't necessarily mean that the nuts have turned bad.
How do you tell if pine nuts is bad?
Pine nuts when spoiled, often develop a bitter or sour taste. If they taste unusually bitter or rancid, it's best to dispose them. Besides, a change in color or smell can be another sign of rancidity. In general, if the nuts have a musky, off smell or their color turns from light creamy to darker, it indicates that they have gone bad.
Tips for storing pine nuts to extend shelf life
• Always store pine nuts in an airtight container.
• Keep them in a dark, cool spot away from heat and light for best quality.
• If you plan to use them within a few days, storing in the pantry is fine. For longer storage, refrigerate or freeze them.
• To extend shelf life, avoid letting the nuts come in contact with moisture or high humidity.
• If you've frozen pine nuts, allow them to thaw in the fridge overnight before using them. This helps to preserve their texture and flavor.
• It's also a good idea to toast the nuts slightly before use, which not only enhances their flavor but also lessens the risk of rancidity.
