Have you ever noticed white material attached to a peach pit after enjoying the flesh? That white coating you see is called callus tissue, a normal and harmless part of the peach’s development. Though it might appear odd, it’s simply a natural growth process.
This callus is made up of cells that aren’t fully specialized yet. Scientists describe these as undifferentiated cells, meaning they’re in a phase where they have not committed to a specific role. This helps protect the pit while the peach develops.
As the peach grows, its pit sometimes produces this callus tissue to act like a protective layer—almost like a cozy blanket shielding the seed. This ensures the seed remains intact and healthy, ready for the day it might grow into a new tree.
So, if you spot this white stuff, know it’s a good sign, showing the fruit’s seed is healthy and growing as it should. It’s just nature’s way of keeping the peach pit safe during its journey inside the fruit.
