Biting into a banana should be soft and sweet. But sometimes, you take a bite and hear an unexpected crunch. That surprising texture is more common than you might think. Experts call it black center syndrome or internal vascular browning.
The banana’s core—the vascular tissue—starts to degrade. As it dries, it turns dark and crunchy. Often, the peel looks perfect while the inside tells a very different story.
Why Bananas Turn Crunchy Inside
Several factors can cause this unusual phenomenon:
- Cold storage: Temperatures below 13°C (55°F) can damage banana cells. The interior dries out, leaving a crunchy core while the peel appears fine.
- Rough handling: Bruises during shipping or packaging can injure the fruit’s inside without affecting the peel.
Internal rot or infection: Fungi or bacteria may attack the core, creating a dry, hard center.
Is It Safe to Eat?
Most crunchy bananas are safe to eat. Use your senses: if it smells and tastes normal, the crunch is just unpleasant—not harmful. However, if it smells sour, fermented, or chemical-like, it’s best to discard it. Crunchy bananas can be deceptive.
