If you’ve ever bitten into a peach and seen white stuff on the pit, don’t worry—it’s perfectly normal. This white substance is called peach callus tissue and is a natural part of how the fruit grows.
Callus tissue is made up of cells that haven’t yet become specialized. Scientists refer to these as undifferentiated cells, meaning they are still developing their final purpose. This is a normal stage in the pit’s growth.
The white tissue forms on the surface of the pit as a protective covering. It’s like a soft blanket that shields the pit while it matures inside the peach.
Finding this white callus tissue means the peach is healthy and growing well. It helps protect the pit from damage as the fruit develops.
So next time you see it, remember it’s a sign of nature’s amazing process at work, helping the peach and its pit grow strong and healthy.
