Pumpkin seeds, also known as pepitas, are a popular fall snack and ingredient. However, before roasting and eating pumpkin seeds, it’s important to properly store the raw, unbaked seeds. Proper storage of unbaked pumpkin seeds helps maintain freshness and prevent spoilage.
Can you freeze unbaked pumpkin seeds?
Yes, unbaked pumpkin seeds can be frozen to extend their shelf life. To freeze unbaked pumpkin seeds:
- Rinse and dry the seeds thoroughly. Make sure no pumpkin pulp remains on the seeds.
- Spread the seeds in a single layer on a baking sheet or plate lined with parchment paper.
- Place the baking sheet or plate in the freezer for 1-2 hours until the seeds are frozen solid.
- Transfer the frozen seeds to an airtight freezer bag or container. Squeeze out excess air and seal.
- Label with the date and store in the freezer for up to 3 months.
Freezing prevents the seeds from spoiling and locks in freshness. Thaw frozen seeds overnight in the refrigerator before roasting and eating.
How should you store unbaked pumpkin seeds in the refrigerator?
Unbaked pumpkin seeds can also be refrigerated for short-term storage:
- Clean and dry the seeds thoroughly.
- Place the unbaked seeds in an airtight container or resealable plastic bag.
- Press out excess air and seal the container.
- Store in the refrigerator for up to 1 week.
The cold temperature of the refrigerator will slow sprouting and spoilage. Store pumpkin seeds in a container rather than a porous bag to prevent them from absorbing fridge odors.
What’s the best way to store raw pumpkin seeds at room temperature?
For room temperature storage:
- Dry the unbaked pumpkin seeds completely after removing strings and pulp.
- Place the seeds in an airtight glass jar, plastic container, or resealable bag.
- Add a silica gel packet to the container to absorb excess moisture and prevent mold growth.
- Store in a cool, dry, dark place like a pantry for 2-3 days.
Avoid warm areas like near a stove or in direct sunlight, which can cause the seeds to sprout more quickly. Refrigerate after 2-3 days for longer shelf life. Check frequently for moisture and signs of spoilage.
What causes unbaked pumpkin seeds to spoil?
There are a few common causes of spoilage for raw pumpkin seeds:
- Moisture – Seeds left damp or wet after cleaning can mold and rot.
- Warm temperatures – Heat causes seeds to germinate and sprout early.
- Air exposure – Oxygen allows aerobic bacteria and fungi to grow.
- Pulp residue – Remaining strings and pulp can become breeding grounds for microbes.
- Improper storage – Storing seeds in porous bags or uncovered containers.
Preventing moisture, heat, air, and contamination are key to maximizing the shelf life of unbaked pumpkin seeds.
How can you tell if raw pumpkin seeds have spoiled?
Signs that unbaked pumpkin seeds have gone bad include:
- Visible mold growth – fuzzy or discolored patches.
- Soft, mushy, or slimy texture.
- Unpleasant sour, bitter, or musty odor.
- Seed germination and sprouting.
- Discoloration or darkening.
If you notice any signs of spoilage, promptly discard the seeds. Do not taste seeds that show signs of mold or spoilage.
Can you eat sprouted pumpkin seeds?
Sprouted, unbaked pumpkin seeds can be eaten as long as mold is not also present. Light sprouting does not make raw pumpkin seeds unsafe to eat. However, germination does gradually deplete nutrients in the seeds over time. For best nutrition and texture, it’s recommended to eat sprouted seeds soon rather than continuing to store them.
Thoroughly rinse sprouted seeds to remove any hulls or seed coats that have loosened. Lightly roasted sprouted seeds for 10-15 minutes at 250°F to firm up the texture before eating.
Discard any seeds with visible mold, even if they have also sprouted. Mold produces toxic byproducts that can cause health issues if consumed.
Conclusion
Storing raw, unbaked pumpkin seeds properly is important for preserving freshness and preventing spoilage or waste. Keep seeds dry and cool in airtight containers. Refrigeration or freezing gives the longest shelf life. Check frequently for moisture, sprouting, and signs of mold or rot. With proper storage methods, unbaked pumpkin seeds can be kept for use in roasted snacks, breads, salads, and other fall recipes.
Frequently Asked Questions
How long do unbaked pumpkin seeds last in the fridge?
In an airtight container in the refrigerator, unbaked pumpkin seeds will last around 1 week before quality starts to decline. Keep refrigerated pumpkin seeds away from high humidity areas like the fridge door to avoid moisture absorption.
What is the shelf life of raw pumpkin seeds?
The shelf life of raw pumpkin seeds depends greatly on the storage method:
- Room temperature – 2 to 3 days
- Refrigerated – 5 to 7 days
- Frozen – 2 to 3 months
Proper drying, sealing from air, and cool temperatures maximize shelf life.
Can you freeze pumpkin seeds with pulp still on them?
It is not recommended to freeze pumpkin seeds with pulp or strings still attached. Remaining pulp will become mushy when frozen and thaw into a soggy mess. Trapped moisture from pulp can also lead to freezer burn or ice crystals forming on the seeds during freezing. For best results, thoroughly dry seeds after removing pulp and strings before freezing.
How do you know if raw pumpkin seeds have gone bad?
Signs that unbaked pumpkin seeds have spoiled include mold, sliminess, sprouting, darkening, sour odor, bitterness, or mustiness. Discard any seeds that show signs of spoilage. Changes in appearance, texture, and smell can indicate microbe contamination or germination. When in doubt, don’t risk eating them.
Can spoiled pumpkin seeds make you sick?
Yes, eating moldy or rotten pumpkin seeds could make you sick. Spoiled seeds can harbor bacteria like salmonella, E. coli, and listeria, as well as toxic molds. Discard seeds at the first signs of spoilage and do not taste them. Seek medical care if you experience concerning symptoms after consumption.
Should you roast sprouted pumpkin seeds?
Lightly roasting sprouted pumpkin seeds can help firm up their texture and improve flavor before eating. Rinse off any loose hulls, pat sprouted seeds dry, and roast at 250°F for 10 to 15 minutes until crispy. Avoid eating large sprouts or any seeds with visible mold. Roast and consume sprouted seeds soon rather than continuing to store them.
