How To Keep Bananas From Turning Brown: 3 Easy Methods Will Make You Surprised


Have you ever had to end up throwing a bunch of overripe bananas in the trash bin? And wondered how to keep bananas from turning brown?

Bananas are one of my family’s favorite fruit. Bananas contain lots of health benefits. Bananas are rich in potassium and fiber, vitamin C and B6 , they can lower the blood pressure and support heart health.


So I always encourage my little kids to eat as much as possible, and I often get a ton of bananas when I come to market.

However, bananas ripen and turn brown rapidly. I have had to throw overripe bananas several times. Throwing brown bananas is such a waste. So I tried to find the way that I can keep the peel’s yellow color appearance longer.

Finally, I found that the main culprit in the banana-browning process is ethylene gas, which is mostly released through the stems, and I came across the methods that let us be able to keep the yellow color of the bananas longer. They are simple, easy to make and the great thing is that you can use the materials you have at home. Do you want to find them out?

Let’s go with me to find out three exciting ways how to keep bananas from turning brown even they’re peeled or unpeeled.

Method 1: Wrapping The Stems

What You’ll Need

Duct Tape:

For this method, you’ll need strong duct tape to prevent the escape of ethylene gas, a compound is the main culprit in the banana-browning process responsible for fruit ripening (You can use whatever brand of duct tape you have at home).

Plastic Wrap:

You can use a plastic wrap as an alternative material to wrap the stem of bananas effectively. You need one that’s durable because a thin type of plastic wrap gets easily to be torn. And please take note that you have to use several layers of plastic wrap to keep the ethylene gas.

Aluminum Foil:

The Aluminum foil seems to be a bit thicker than the plastic wrap, so it can be another great alternative. Its malleability makes it easy to wrap around the stems without the need of any elastic bands.

You also need a good pair of scissors to cut the duct tape, plastic wrap, or aluminum foil into desired pieces. In case you’re using an old pair of scissors, you should check the blade for any rust.

Step by Step In Keeping Bananas From Turning Brown

1. Get Your Materials

You can choose one of three wrapping materials to use: duct tape, plastic wrap, or aluminum foil. Don’t forget your scissors

2. Decide The Method Of Wrapping

You can wrap the bananas by singles or by the bunch. But what is the difference between the two wrapping methods?

If you wrap each stem individually, this will make the bananas keep its yellow color longer up to about seven days. However, if you want to get a faster way of preserving the bananas, you can choose the method of wrapping the entire crown of a bunch.

Either way, the main purpose here is to prevent the ethylene gas from escaping. Take note that the ethylene gas from the stems won't entirely stop releasing. However, you can slow down the ripening process a bit.

3. Wrap The Stems

With duct tape: First, cut off the tape into a 2-inch strip, and stick it around the top part of the dark stem. You should eliminate all air bubbles by pressing the tape down hard. Second, cut a larger tape strip and wrap it tightly around the stem.

With plastic wrap and aluminum foil: both materials have the same steps to follow. Cut off a three- or -four-inch-wide section of plastic wrap or aluminum foil then roll the stem tightly.

Note: If you’ll be wrapping the banana individually, separate each banana from the stem before you cover.

Method 2: Sealing The Whole Fruit

What You’ll Need

For this method, you’ll need several resealable plastic bags to seal the whole fruit; this will protect your bananas in the refrigerator.

If you don’t have resealable plastic bags, you can use any plastic bag you have at home as an alternative.

Steps to Follow

1. Prepare The Items You’ll Need

Now you get your bananas and resealable plastic bags, right? Unlike the first method, you need to separate the banana from the stem for the second method.

2. Seal The Bananas

Put your bananas into a resealable plastic bag. If the plastic bag is big enough, you can place two bananas in one bag. Remember that before sealing the zipper, you press all the air out as possible. Now store these bags of bananas at the bottom of your refrigerator. The bananas can stay fresh for about a week longer.

Method 3: Adding Some Juice

Fruit J​uice

Fruit juice can keep the peeled bananas from oxidizing or turning brown. So, for the third method, you need to prepare some fruit juice, one cup is enough to dip 2-4 bananas.

Lemon is the most popular ingredient that you can use to make fruit juice. You can also use other fruit juice alternatives such as lime juice, apple juice, pineapple juice, or grapefruit juice.

Vitamin C Solution

In case you have no fruit juices available, vitamin C is one of the great solutions to slow down the oxidation of bananas. To make the vitamin C solution, crush one chewable vitamin C, then dissolve it in half a cup of water.

Soda Water

Soda water is a neutral-tasting alternative that you can use. Don’t be confused with tonic water, the strong flavor of tonic make it not sit well with bananas. Soak the bananas in soda water before you serve or store them

Equipment You’ll Need


You need a small bowl to contain your fruit juice, vitamin C solution, or soda water. I won’t recommend you to use metal bowls because you’ll be dealing with citric acid. A glass or plastic bowl is highly recommended.

Knife And Cutting Board

To cut the peeled bananas into slices, you’ll need a knife and a cutting board. Definitely, you won’t expect any meat residue to contaminate your bananas, make sure that the cutting board being used is intended for fruits and vegetables

Pastry Brush

You need to coat the cut surfaces of bananas with the fruit juice; a pastry brush will be your good aid for this step. You can also use a spray bottle to spay the fruit juice on the bananas more easily or use a resealable plastic bag to mix banana slices and fruit juice.

Airtight Container

You need an airtight container to keep bananas longer in the refrigerator after coating the bananas with fruit juice.

Steps to Follow

1. Prepare Your Materials

Using your knife and cutting board to peel and slice bananas. Choose one of the fruit juices, vitamin C solution or soda water you’ll use to keep the bananas from turning brown.

2. Coat The Bananas

Using a pastry brush to coat the bananas with the juice.  Or pour the juice to a spray bottle and spray the juice over the banana slices.

If you use a resealable plastic bag, you can place the bananas and the juice together into a resealable plastic bag then gently mix.

3. Storage

You can use the sliced bananas for your salads or pies immediately.

If you want to store bananas, keep them in an airtight container and refrigerate in your fridge. 


If your bananas have turned brown or almost black, do not quickly throw them into the trash bin. 

Some below suggestions can help you avoid the waste:

1. Place peeled bananas in an airtight plastic container then put it in the freezer: You can use frozen bananas for cooked or baked meals.

2. Make Dried Banana chips: 

Simply to dehydrate your banana slices by a food dehydrator, you'll have crunchy banana chips.

3. Bake banana bread: You can use over-ripe bananas in tasty treats. Banana bread is the sweetest and most flavorful when you use over-ripe bananas.

4. Use your over-ripe bananas for a Biscoff banana apple smoothie:

 For this smoothie, you’ll need one over-ripe banana, half an apple peeled and cored, four Biscoff cookies, one cup of milk, 1/2 teaspoon of vanilla extract, a dash of cinnamon, and some ice cubes. Place over-ripe banana, apple, and Biscoff cookies into the blender, mix until smooth. Then add the other ingredients, continue blending. So you had a tasty drink, right?
