1. What is mold on cheese?
Mold is a type of fungus that grows on food, especially when exposed to moisture and wear. Some molds are intentional, such as the blue veins in blue cheese, while others are readily available and can be used to spoil food.
Types of mold on cheese:
Penicillium – waste in cheeses such as Roquefort, Gorgonzola and Camembert.
Green, black, or white fluffy molds – dispersion; may produce mycotoxins.
Surface mold on hard cheese – This can often be removed.
