Spread the yogurt on dehydrator tray covered with parchment paper in an even, thin layer (about1/8-inch thick)
Dehydrate at 135F for about 6-8 hours, until completely dry and brittle. Rotate tray every couple of hours and flip-over the yogurt bark halfway through the drying time
Remove from the dehydrator and let cool.
Vacuum-seal and freeze until you’re ready to put it into a backpack; OR unrefrigerated and without vacuum sealing, dehydrated yogurt can last at room temperatures in a zip lock bag for about a week
