Roasted sunflower seeds should be immediately packaged, sealed, and stored with food desiccants inside. Keep them in a dry, cool place. For opened sunflower seeds, ensure proper sealing. You can place a resealable bag over the packaging to further seal it, trying to expel as much air as possible to enhance moisture resistance.

2. Purchased freshly roasted peanuts should be allowed to cool before being placed in containers or bags. Add a food desiccant to the bag to prevent the peanuts from getting moldy.

3. Unconsumed sunflower seeds should be sealed and stored with food desiccant, then frozen in the refrigerator. This not only keeps the seeds crispy and prevents rancidity but also deters pests.
