The way I read it is the ripening of fruit is the breakdown of pectin
molecules into sugar molecules (pectose to fructose). Pectin is what makes
fruit (and jams and jelly) firm. So the fruit gets softer and softer and
sweeter and seeter until it turns to mush. It changes colour at the same time.
So "rotten" fruit is really not rotted. Rot is decomposition due to mould
fungus eating the fibres, eg rotting wood. I'd say if it isn't fuzzy it's
not mould. Well, peaches are already fuzzy but not that kind of fuzz.

And here I was going to say it's because they grow inside out....

It's definitely mold and it's on the inside around the pit. I can even
smell it.

That kills my theory.

We encountered the interior mold on peaches earlier this year. IIRC they
came out of California. I dissected one and there was an opening at the
stem end that went into the pit, apparently the mold started there and
covered the entire pit. I took them back where we got them and the store
manager refunded our money. The produce guy there is a long time friend
of mine and we cut several more and they were all moldy inside. AFAIK
the store returned them to whomever sold them to them.

Well I didn't pay my sister for them and if I tried to return them she'd
just throw them at me! LOL Maybe it's weather related?

A friend brought us some very large peaches from western Colorado
on his way back from vacarion, in exchange for making him a peach pie.
A few of them were moldy around the seed, also, and two of those had a
couple of earwigs each crawling around inside the seed. Ugh.

Oh ick. I didn't find any earwigs at least. The peaches I got are from
eastern Colorado.

Kathy, Peaches with split pits will mold on the inside because air is
available to the inside of a peach. Split pits are usually caused by
too much rain. Also earwigs which have no interest in the peach flesh
enjoy living in the open space of the split pit. A little molding
around split pit fruit is usually okay. Split pit fruit is considered
number 2 fruit and should be purchased only from the farmer at a
discount price.CC

That would explain it. My sister said the weather had turned off rainy for
awhile. I didn't like the way they smelled so I tossed all of the moldy
ones. I figure if I didn't like the way they smelled they probably wouldn't
taste any better.
