Answer ➜ Place the seeds in an airtight container and store them in your refrigerator. They will last up to a week in the refrigerator, so you should make sure you roast them before the week is out.
(Raw pumpkin seeds for one, that is made through roasting fresh seeds can last for at least 2 months when refrigerated in an air tight container.)
