  • Soft or chewy texture (should be firm)

Room Temperature Safety

While dried shelled pumpkin seeds are not highly perishable in the same way as cooked foods, general food safety advises against leaving any food item exposed for extended periods. The 2-hour rule (1 hour above 90°F/32°C) primarily applies to perishable foods to prevent bacterial growth.

The 'danger zone' (40°F–140°F) is where bacteria multiply rapidly in perishable foods. While dried seeds have low water activity and are less susceptible to bacterial growth, prolonged exposure to these temperatures can accelerate rancidity and quality degradation.

For optimal quality and to prevent rancidity, shelled pumpkin seeds should be stored in a cool, dark, dry place. Avoid prolonged exposure to warm temperatures, direct sunlight, or high humidity.

Expert Tips

Safe Handling

1

Always store shelled pumpkin seeds in airtight containers to prevent moisture absorption, rancidity, and pest infestation.

2

Keep away from direct sunlight and heat sources, which can accelerate spoilage.

3

Check for signs of spoilage before consumption.
