Why Is My Cheese Turning Blue? The Surprising Science Behind It

Have you ever opened your refrigerator to find your once-pristine cheese has turned an alarming shade of blue? While it may seem like a culinary catastrophe, blue cheese is actually a delicacy enjoyed by many. But what causes cheese to turn blue in the first place? Let’s dive into the fascinating world of cheese microbiology to unravel the mystery of the blue cheese.

What Is Blue Cheese?

Blue cheese is a type of cheese that has been intentionally inoculated with specific strains of mold, typically Penicillium roqueforti or Penicillium glaucum. These molds are responsible for the characteristic blue-green veins that run throughout the cheese.

Why Does Cheese Turn Blue?

The blue color in cheese is caused by a specific type of mold called Penicillium roqueforti. This mold is a natural inhabitant of caves and other environments with high humidity. When introduced to cheese, the mold grows and produces a blue-green pigment called roquefortine C. This pigment is what gives blue cheese its distinctive color.

Is Blue Cheese Safe to Eat?

Yes, blue cheese is safe to eat. The mold used to create blue cheese is not harmful to humans. In fact, some studies suggest that it may even have some health benefits, such as reducing inflammation and improving digestion.

How to Prevent Cheese from Turning Blue

If you prefer your cheese without the blue veins, there are a few things you can do to prevent it from turning blue:

• Store cheese properly: Keep cheese in an airtight container in the refrigerator. This will help to prevent the growth of mold.
• Avoid contact with moisture: Moisture can encourage the growth of mold. Avoid touching cheese with wet hands or storing it in a humid environment.
• Use waxed paper: Wrapping cheese in waxed paper can help to create a barrier between the cheese and the air, which can help to prevent mold growth.
