Vent your poly (plastic) bag with a few holes or transfer ripe jujubes to a cloth produce bag.

Store in the fruit drawer with moderate humidity for up to a month. 

You can also place them in an airtight container and keep in the refrigerator for up to a week.

To freeze jujubes, place them on a cookie sheet covered in parchment at least an inch apart. Freeze completely, then transfer them to zipper bags and freeze for up to six months.
