Should raw pumpkin seeds be refrigerated?
Yes, raw pumpkin seeds can be refrigerated, and doing so is often recommended to extend their shelf life. The cold environment of a refrigerator helps prevent the seeds from becoming rancid, especially if they are not consumed within a few weeks after opening. While raw pumpkin seeds may not necessarily spoil quickly, the oils in the seeds can become oxidized when exposed to warm temperatures, leading to a less enjoyable flavor and texture.
Refrigerating raw pumpkin seeds can also keep them fresh longer than storing them at room temperature. If you buy pumpkin seeds in bulk or have opened a bag, consider placing them in an airtight container before refrigerating to prevent moisture absorption, which can lead to mold growth.
How long can raw pumpkin seeds last if refrigerated?
When stored properly in the refrigerator, raw pumpkin seeds can last for about 6 to 12 months. Their shelf life largely depends on how they were packaged and stored before refrigeration. If the seeds are kept in an airtight container and away from moisture, they can maintain their quality for an extended period.
It’s important to check the seeds periodically for any signs of spoilage, such as an off smell or discoloration. If they show any of these signs, it’s best to discard them. Always prioritize freshness to ensure you’re getting the best flavor and nutritional benefits from your pumpkin seeds.
What is the best way to store raw pumpkin seeds?
The best way to store raw pumpkin seeds is to keep them in an airtight container. This helps to preserve their freshness by protecting them from exposure to air, moisture, and light, all of which can lead to rancidity.
