Bananas can be a healthy and delicious snack any time of the day. Full of nutrients and vitamins such as potassium, a banana is a low-fat way to keep you sated until your next meal. Like most fruit, bananas can go bad quickly. Given the environment, bananas can last from three days to a little over a week. Turning your bananas into banana chips can extend their shelf life and provide you with a highly portable snack. You can make your own banana chips by baking them in the oven.
Preheat oven to 93.3 degrees Celsius. Place a sheet of parchment paper onto the baking pan.
Cut the bananas with the knife into 3- to 6-mm (1/8- to 1/4-inch) thick slices. Dip the slices into the lemon juice and arrange them on the baking pan so that they do not overlap.
Place the baking pan into the oven and cook the banana slices for 30 minutes. Remove the pan from the oven and flip the slices over with a fork.
Replace the baking pan into the oven. Continue removing the pan and flipping the banana slices every 30 minutes for a total of 3 1/2 to 4 hours.
Remove banana chips and place them on a plate lined with a paper towel.
