What is this cotton-like stuff growing on my pizza sauce?
The sauce was to expire in Nov 2013. I kept it in the fridge all the time. The thing that grew on it was white in color (just like cotton). There was a greenish center. The overall "ball" was about 1 cm in diameter, and they were all over in the bottle.
I don't have a picture of it, because I had to throw it out. I don't know what it was, or how it started growing.
What was it? Why was it there?
Best Answer
It's mould. You've probably seen it growing on bread. Refrigeration slows it down, but eventually it'll grow.
You didn't say when you bought it and opened it. Perhaps your fridge is not set cold enough?

Like @sarino and @megasaur mentioned already, it is mold and you did the right thing by throwing it away. This link explains pretty well why mold grows on the food: http://wanttoknowit.com/why-does-mold-grow-on-food/
Also, the reason that food stays good in these unopened bottles in normal temperatures is that the food is vacuum sealed, so it doesn't come into contact with air or outside moisture. Once its opened, it is highly recommended to go into the fridge straight away, like you did.
