What is the mold on the inside of a peach?

The mold on the inside of a peach is typically a type of fungus, such as Botrytis cinerea, which causes gray mold, or other species that thrive in moist environments. This mold can develop when the fruit is bruised or damaged, allowing spores to infiltrate. It appears as fuzzy or discolored spots and can affect the fruit's taste and safety for consumption. If you encounter mold inside a peach, it's best to discard the fruit to avoid health risks.
