Mondo Knows Facts
Camembert's white rind is a living mould
Penicillium camemberti grows on the surface and softens the cheese beneath The white coat on a camembert is a mould introduced during making, either sprayed on or carried in from the ripening room. As it grows, the mould consumes lactic acid and raises the surface pH, which lets its enzymes break down protein and fat. That is why a ripe cheese bulges under the rind while the centre may still be chalky. It sits in Mondo's food collection, one of 200 facts that each trace back to the reference below.
