Blue cheese

Blue cheese

Blue cheese is mold cheese made from blue to greenish molds such as Penicillium roqueforti and Penicillium glaucum . Variants with greenish mold partly as a green cheese called.

The non-toxic mushrooms usually run through the cheese like veins, which is due to the manufacturing process: The blue to green noble mold is still grown on loaves of bread until these are completely pervaded by mold. The mold through the mold is dried, finely ground and liquefied, then the mold mass is introduced into the unripe cheese with a coarse syringe. As the fungus grows, it branches more or less deeply and finely, as far as this is possible due to the structure of the break and its treatment. Depending on the type, the cheese wheels are also repeatedly “ pricked ” during the ripening period , that is, pierced with long, thick needles in order to allow more oxygen to penetrate inside and thus promote further fungal growth.

The common bread mold , unlike noble mold, is inedible and is not suitable for making mold cheese.

In a production variant, the mixture of already before the skimming of the cheese break and whey with fungal spores inoculated, which spread the fungus in the later cheese evenly. In this case too, after a certain period of ripening, the cheese is often pricked to help the fungus grow.

Pregnant women are often advised not to eat blue cheese, but well-founded justification seems difficult. Blue cheese is said to promote the growth of Listeria bacteria because it is more humid and less acidic than other types of cheese, a rather inconclusive claim, especially since in Germany foods have to be checked for Listeria. The recommendation may even go back to a confusion with raw milk cheese . One thing is certain, however: Listeria are killed by cooking. However, the uncertainty also applies the other way round: Why you are certain that blue mold is basically non-toxic and how this is tested remains unclear.
