How can I effectively dry papaya seeds for storage and future use?

To effectively dry papaya seeds for storage and future use, first remove the seeds from the fruit and wash them to remove any pulp. Then, spread the seeds out on a paper towel or a mesh screen in a well-ventilated area away from direct sunlight. Allow the seeds to air dry for several days, stirring them occasionally to ensure even drying. Once the seeds are completely dry, store them in an airtight container in a cool, dark place.
