Beef jerky is a convenient snack; it stays good for months, does not need to be refrigerated and is light and easy to carry. Nutritionally, 100 grams of chopped and formed beef jerky contains 54 percent of your daily zinc, 41 percent of your daily phosphorus, 30 percent of your daily iron, 17 percent of your daily potassium and 15 percent of your daily selenium, according to SELFNutritionData. When you make your own beef jerky in the dehydrator, removing it at the right time is essential. If you leave the jerky in the dehydrator too long, it will become hard and difficult to chew.

Remove a single piece of jerky from your dehydrator.

Bend the piece of jerky, if possible. If it bends very slightly then breaks, it is perfectly done. If it snaps easily, it is overdone. Remove the jerky from the dehydrator immediately if either of these is the case.

Return the jerky to the dehydrator if it bends easily or feels moist to the touch. Check it every 30 to 60 minutes until it is done, then remove it from the dehydrator. Depending on your dehydrator and the thickness of the jerky, it may take between four and 12 hours for your jerky to fully dry.
