Why Are Bananas Splitting Open? And How To Stop It?

Bananas are one of the most popular fruits around. Their sweet taste, soft texture, and nutritional benefits make them a staple food for many. However, it can be frustrating when bananas split open before they are ripe enough to eat. A banana splitting open renders it unappealing and unusable.

Fortunately, there are several ways to prevent bananas from splitting prematurely. With a few simple tips and tricks, you can keep bananas intact and enjoyable. In this article, we will explore the reasons why bananas split open and actionable solutions to stop it from happening.

What Causes Bananas to Split Open?

To understand how to prevent banana splitting, it is important to first know what causes it.

There are a few key factors that can lead to a banana’s skin rupturing:

1. Rapid Temperature Changes

Bananas are extremely sensitive to temperature shifts. If a banana is exposed to sudden or drastic heating or cooling, the contents expand or contract at a different rate than the peel. This puts pressure on the skin and causes it to split open.

For example, moving a banana from the cold fridge directly to the hot outdoors can shock the fruit and result in splitting. Similarly, microwaving or freezing a banana whole leads to the pulp expanding faster than the skin can stretch.

2. Ripening Process

As bananas ripen, the starch inside turns to sugar. This conversion causes the flesh to become softer and the skin more pliable. If the ripening happens unevenly, pressure builds up in localized spots. This can overwhelm the peel’s integrity and cause splits or cracks.

Overripe bananas are especially prone to rupturing as the skins lose elasticity and strength while the insides become almost liquefied. Ripe bananas should be eaten soon rather than left to over-ripen.

3. Physical Damage

Direct physical impacts can also cause banana skin splitting. Dropping, squeezing, or otherwise damaging the fruit during handling and transportation creates weak spots and bruising. These compromised areas are likely to split open as the banana continues to ripen.

Being gentle when picking, carrying, and storing bananas helps minimize this type of mechanical damage. Cushioning bananas from direct blows or compression is key.

Tips to Stop Bananas from Splitting Open

Luckily, there are many ways you can prevent your bananas from splitting before you are ready to eat them.

Here are some useful tips:

1. Regulate Temperature

Avoid subjecting bananas to sudden temperature shocks. Do not refrigerate whole bananas. Allow refrigerated bananas to come to room temperature gradually before exposing them to warmer environments.

Keep bananas away from direct sun, heat vents, ovens, etc. Maintain a stable, moderate temperature during storage and transport. Wrapping the stems with plastic wrap helps insulate bananas from temperature fluctuations.

2. Slow the Ripening

You can delay the ripening process by:

  • Separating unripe bananas from ripe ones. The ethylene gas released by ripe bananas triggers faster ripening.
  • Storing green bananas in a cool, dark place. The refrigerator is ideal, but allow them to warm before exposing to heat.
  • Avoiding sealing bananas in airtight bags or containers. Restricted airflow concentrates ripening ethylene.
  • Using acidic fruit juices like lemon, orange, or pineapple juice to scrub the banana peels. This washes away ripening triggers.

Slowing down ripening gives the skin more time to adapt to the changes occurring inside the fruit.

3. Handle with Care

Prevent mechanical damage by being gentle when handling bananas. Do not drop, throw, or step on them. Avoid squeezing or deforming the fruits during storage and transport.

Cushion bananas with soft packaging like paper or bubble wrap. Stack them carefully and avoid crushing the bottom layers with excessive weight. Carry and store stems up to better distribute the fruit’s weight.

Trim stems with scissors rather than breaking them off to prevent splitting at the top. Cut a crosshatch pattern into the peel before freezing to allow for expansion.

4. Use Fruit Protectors

For extra protection, slip bananas into individual fruit sleeves, tubes, or wraps designed to shield from physical and temperature stresses. These guards prevent friction between fruits while also insulating from thermal shocks.

You can also wrap bananas in plastic wrap, aluminum foil, or paper. Sealable plastic bags work but avoid fully sealing as trapped ethylene gas hastens ripening.

5. Know When to Discard

Check stored bananas regularly and discard any that become overripe. Use ripe bananas within a couple days and do not let them progress to the point of skin splitting.

Compost bananas that split open rather than consuming. The exposed flesh is vulnerable to microbial contamination. Enjoy bananas at their peak ripeness for best flavor, texture, and nutrition.


A banana splitting open before its ideal ripeness can be inconvenient and render it inedible. However, this common problem can be prevented with optimal storage, gentle handling, and slowing the ripening process. Pay close attention to temperature fluctuations, progression of ripening, and physical damage. With the right precautions, you can keep bananas intact and enjoyable for longer.
