What is the white stuff in salami?

Salami is a type of cured sausage that is made from ground meat, typically pork or beef. It is typically fermented and dried, and the fermentation process is what produces the white stuff on the surface of the sausage. This white stuff is a type of mold that is called penicillium nalgiovense. It is harmless to eat and actually contributes to the flavor and texture of the salami. The mold helps to break down the proteins in the meat, which makes the salami more tender and flavorful. It also helps to prevent the growth of harmful bacteria.

Some people may be allergic to penicillium nalgiovense, so it is important to read the label of the salami before eating it if you have any concerns.
