Blue cheese, with its pungent aroma and distinctive veined appearance, is a culinary delight for some and an acquired taste for others. Its characteristic blue or greenish streaks are the result of mold cultures deliberately introduced during the cheesemaking process. But a common question lingers: is this mold safe to eat, and could it even be beneficial? Let’s delve into the fascinating world of blue cheese to separate fact from fiction.
Understanding Blue Cheese and Its Mold
Blue cheese isn’t just one type of cheese; it encompasses a variety of cheeses, each with its unique flavor profile and texture. What unites them is the presence of specific molds from the Penicillium genus. These molds are what give blue cheese its signature look and taste.
The Cheesemaking Process and Mold Introduction
The creation of blue cheese is a meticulous process. Milk, typically cow’s milk but sometimes sheep’s or goat’s milk, is curdled, and the whey is drained. This forms the base cheese. What sets blue cheese apart is the introduction of Penicillium spores. These spores can be added directly to the milk or sprayed onto the curds.
After the curds are formed, they are pressed and shaped. To allow the mold to flourish, the cheese is pierced with needles. These tiny holes provide oxygen, which is essential for the Penicillium mold to grow and spread throughout the cheese, creating the characteristic blue veins.
Common Types of Penicillium Molds Used
Several Penicillium species are commonly used in blue cheese production. The most prevalent are Penicillium roqueforti and Penicillium glaucum. Each species imparts a slightly different flavor and texture to the cheese.
Penicillium roqueforti is responsible for the sharp, tangy, and sometimes peppery flavor found in many blue cheeses, including Roquefort itself. Penicillium glaucum tends to produce a milder, creamier flavor, often found in cheeses like Blue Castello.
The Safety of Mold in Blue Cheese
The million-dollar question: is the mold in blue cheese safe for consumption? The answer is a resounding yes, under normal circumstances.
Specific Molds vs. Harmful Molds
It’s crucial to distinguish between the beneficial molds used in cheesemaking and the harmful molds that can grow on spoiled food. The Penicillium molds used in blue cheese production are carefully selected and cultivated. They are specifically chosen for their ability to impart desirable flavors and textures without producing toxins harmful to humans.
Harmful molds, on the other hand, can produce mycotoxins, which are toxic substances that can cause illness. These molds are often found on spoiled fruits, vegetables, and other foods. They are visibly different and should never be consumed.
Regulations and Quality Control
The production of blue cheese is subject to strict regulations and quality control measures. Cheesemakers carefully monitor the entire process, from the selection of milk to the aging of the cheese, to ensure the safety and quality of their products. They test for the presence of harmful bacteria and molds, ensuring that only the intended Penicillium species are present.
