Recipe Facts And Tips

Here are a few facts and tips to get the perfect banana chips at home.

  • Use a plastic mesh liner on each dehydrator tray and place the bananas on it. It will prevent the dried bananas from sticking to the dehydrator tray.
  • Leave space between each slice of banana to prevent them from sticking to each other.
  • Dip the banana slices in a pretreatment solution like lemon juice to prevent them from browning.
  • Use firm but ripe bananas for the best-flavored banana chips.

How Ripe Should The Bananas Be Before Dehydrating?

The bananas you use to make banana chips should be ripe but firm. It will give banana chips the perfect taste and texture.

Over-ripe bananas will become mushy and give a different taste when dehydrated. Using hard and not ripe bananas will not give you sweet-tasting banana chips.

For best results, taste a piece of banana to check if it has a sweet flavor that is perfect for dehydrating.

How To Pretreat Banana Chips?

The purpose of pretreating bananas is to prevent them from turning brown when dehydrating. 

Mix 3 tablespoons of lemon juice with 3 tablespoons of water to make the pretreatment solution. You can even use a citric acid-based pretreatment product like Fruit Fresh. However, making one with fresh lemon juice provides better results.

Make sure to test a few banana slices dipped in a pretreatment solution to detect any major change of flavor. If so, you need to make a new pretreatment solution, as a flavor change can cause your dehydrated banana chips to taste different.

How To Keep Banana Chips From Sticking When Dehydrating

Banana slices stick to the dehydrator tray as the moisture is removed from them. When banana chips stick to the dehydrator tray, it will be difficult to remove them once done. The dried banana chips could break when trying to remove them from the tray.

It is the reason why you should line each dehydrator tray with a plastic mesh liner. Then the banana chips won’t stick to the dehydrator tray as the non-stick mesh lies in between.

These plastic trays are flexible. You can bend them to help release the banana chips before removing them.

How To Identify When Bananas Are Done

When identifying if banana chips are done, you should not try checking them when they are hot. Take the tray out of the dehydrator and wait until the banana chips cool down to check if they are done.

You should remove one chip from the tray when checking banana chips for doneness. If it tears, the edges stick to the tray, or it feels mushy, which means there is still some moisture. Put them back in the dehydrator.

Sometimes, when the bananas are not sliced in equal thickness, the thick ones could take more time to dehydrate. If so, keep only the thick ones and check the rest to see if they are done. Keeping the thicker ones for about an hour extra should do the job.

How To Store Dehydrated Bananas

Conditioning is vital in ensuring that you can store your banana chips for a long time. 

Appropriate conditioning of your banana chips helps reduce the chance of mold developing. It usually occurs when your bananas are not completely dehydrated, and there is a bit of moisture left in them.

Place the cool dehydrated banana chips in a glass jar and keep them in a safe area without direct sunlight. Check for moisture inside the jar every day for up to a week.

If you find moisture in the banana chips, dehydrate them again. Repeat conditioning for the dehydrated banana chips to confirm no moisture left the second time round.

Once the banana chips are completely dehydrated, you can store them in an airtight container for up to 6 months. If you vacuum seal them, you can store them for up to one year.

About Dehydrators

Knowing the different types of dehydrators is also vital when drying banana chips. Dehydrators with a set temperature usually run at a steady but high temperature, like 165 F. (Fahrenheit) 

Your banana chips will dry much faster in this type of dehydrator. However, you need to pay close attention when making banana chips using a dehydrator with a set temperature.

Dehydrators with a digital control setting allow you to control at which temperature you need your banana chips to dry. These types of the dehydrator are relatively more expensive than ones with a set temperature.

Other Ways To Use Dehydrated Bananas 

Making banana chips is not the only way to use your dehydrated bananas. Here are a few other ideas to make use of dehydrated bananas.

  • Use them as a topping in yogurt.
  • Add them to oatmeal or breakfast porridge.
  • Add them to baked granola.
  • Include them in a DIY trail mix.
