Penicillium Roquefortij

Penicillium roqueforti is a type of mold used to make blue-veined cheeses, such as Roquefort, Gorgonzola, and Stilton. It is a naturally occurring mold that grows on rye or wheat bread, or it can be cultured in a laboratory. The mold gives blue cheese its characteristic sharp flavor and pungent aroma.

This mold is used as a starter culture in the production of blue cheeses. It is added to the cheese curd to create the distinctive blue veins and complex flavor profile. It is most commonly found in blue cheese itself, and in foods that feature blue cheese as a primary ingredient.

Penicillium roqueforti is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural component of many traditional cheeses and is not associated with adverse health effects when consumed as part of a normal diet. International bodies like EFSA have also evaluated molds used in cheesemaking, and no specific concerns have been raised regarding this organism in the context of its use in cheese.
