How can I effectively store papaya seeds for future use?

To effectively store papaya seeds for future use, first remove them from the fruit and clean off any pulp. Then, dry the seeds thoroughly by placing them on a paper towel in a well-ventilated area for about a week. Store the dried seeds in an airtight container in a cool, dark place, such as a pantry or refrigerator. Make sure to label the container with the date and type of seeds for easy identification. Stored properly, papaya seeds can remain viable for up to 5 years.
