Factors that Affect the Shelf Life of Pumpkin Seeds

• Moisture: Pumpkin seeds are highly susceptible to moisture, which can cause them to quickly spoil, become rancid, or moldy. Be sure to store them in a cool, dry place with a low relative humidity.
• Air Exposure: Make sure the container in which the pumpkin seeds are stored is airtight so that oxygen cannot get inside and cause oxidation of the healthy fats, leading to spoilage.
• Heat: High temperatures can accelerate the breakdown of natural oils in pumpkin seeds, reducing their shelf life. Store them away from direct sunlight and sources of heat.
• Quality: The quality of the pumpkin seeds you buy can affect their storage life as well. Be sure to purchase fresh, high-quality pumpkin seeds that have been harvested and stored correctly for optimum shelf life.

Putting these factors into practice will help ensure your pumpkin seeds stay fresh for longer periods of time. Choose an airtight container for storage and keep it in a cool, dry place away from direct sunlight and heat sources for optimal results.
