Does Blue Cheese Have Mold in It? Unveiling the Secrets of Fungi-Filled Flavor

Yes, blue cheese definitively contains mold. However, before alarm bells ring, understand that the mold is a specifically cultivated, safe-to-eat variety deliberately introduced to create its distinctive flavor, texture, and appearance. It’s not the same kind of mold that spoils food. In fact, it’s what makes blue cheese, blue cheese.

The Moldy Magic Behind Blue Cheese

The captivating, pungent flavor and striking blue or green veins characteristic of blue cheese are the direct result of the deliberate introduction and growth of Penicillium mold cultures during the cheesemaking process. These aren’t random, unwanted molds; they are carefully selected and cultivated strains, each contributing to a specific flavor profile and texture.

The process typically involves piercing the cheese with needles or wires, allowing air to circulate and encourage the mold to grow throughout the interior. As the Penicillium molds thrive, they produce enzymes that break down fats and proteins, releasing complex flavor compounds that give blue cheese its signature sharpness, tanginess, and sometimes even a slightly sweet or nutty taste. The resulting visually striking marbled effect only adds to its allure.

Penicillium Species: The Culinary Culprits

Several species of Penicillium mold are used in blue cheese production, the most common being Penicillium roqueforti and Penicillium glaucum.

• Penicillium roqueforti is the traditional mold used in Roquefort cheese, and is also commonly found in other blue cheeses like Gorgonzola and Stilton. It contributes to the characteristic strong, pungent flavor and blue-green veins.

• Penicillium glaucum, though less common, is used in some varieties, offering a slightly milder flavor profile and bluer veins.

The specific Penicillium strain used, along with the milk type (cow, sheep, or goat), aging process, and other factors, all contribute to the unique characteristics of each type of blue cheese.

Food Safety and Blue Cheese: Addressing Concerns

A natural question arises: if mold is present, is blue cheese safe to eat? The answer, unequivocally, is yes. The Penicillium molds used in blue cheese production are specifically chosen for their safety and lack of toxin production.

Unlike harmful molds that grow on spoiled food and can produce mycotoxins (toxic substances), the molds used in blue cheese are carefully selected and tested to ensure they are safe for human consumption. The cheesemaking process itself further contributes to safety by controlling the environment in which the mold grows, inhibiting the growth of undesirable microorganisms.

However, individuals with mold allergies may experience reactions when consuming blue cheese. The severity of the reaction can vary depending on the individual’s sensitivity and the amount of cheese consumed.

For most people, however, blue cheese is a safe and delicious component of a varied diet.

Frequently Asked Questions (FAQs) About Blue Cheese and Mold

1. What are the benefits of eating blue cheese?

Beyond its distinctive flavor, blue cheese offers several nutritional benefits. It’s a good source of calcium, essential for bone health, and protein, important for muscle building and repair. It also contains vitamins and minerals, including vitamin A, vitamin B12, phosphorus, and zinc. Some studies suggest that certain compounds in blue cheese may have anti-inflammatory properties, although more research is needed in this area.

2. How do I store blue cheese properly?

To maintain its quality and prevent the growth of unwanted molds, store blue cheese properly. Wrap it tightly in parchment paper or cheese paper and then place it in a resealable container in the refrigerator. This helps prevent it from drying out and absorbing odors from other foods. Ideally, store it in the crisper drawer, where the humidity is higher.

3. How long does blue cheese last?

Properly stored blue cheese can last for 2-3 weeks in the refrigerator. However, it’s best to consume it within a week or two of opening the package for optimal flavor and texture. Watch for signs of spoilage, such as a sour or ammonia-like smell, excessive sliminess, or the appearance of undesirable molds.

4. Can I freeze blue cheese?

Freezing blue cheese is not recommended, as it can alter the texture and flavor. The cheese may become crumbly and lose some of its characteristic tanginess. If you must freeze it, wrap it tightly in several layers of plastic wrap and then place it in a freezer bag. Use it within a few months for best results, and expect some textural changes. Use it primarily in cooked dishes after thawing.

5. What is the difference between different types of blue cheese?

The differences between blue cheese varieties stem from factors like the type of milk used (cow, sheep, or goat), the specific Penicillium strain used, the aging process, and the region of origin. Roquefort, for example, is made exclusively from sheep’s milk in France. Gorgonzola is a cow’s milk blue cheese from Italy. Stilton is a cow’s milk blue cheese from England. Each cheese boasts a unique flavor profile and texture.

6. Is the mold in blue cheese vegan?

No, blue cheese is not vegan. It is made from animal milk (cow, sheep, or goat) and contains animal rennet, an enzyme used to coagulate the milk. The Penicillium mold itself is a fungus, not an animal product, but the presence of dairy makes blue cheese unsuitable for a vegan diet.

7. Can I eat the rind of blue cheese?

Whether or not you can eat the rind of blue cheese depends on the specific type. Some blue cheeses have natural rinds that are perfectly safe and even flavorful to eat, contributing to the overall taste experience. However, some have waxed or otherwise treated rinds that should be removed before consumption. Check the label or ask the cheesemonger for guidance.

8. What are some good pairings for blue cheese?

Blue cheese pairs well with a variety of foods and beverages. Its salty, pungent flavor complements sweet fruits like pears, apples, and grapes. It’s also delicious with nuts, such as walnuts and pecans. For beverages, try pairing it with sweet wines like Port or Sauternes, or with bold red wines like Cabernet Sauvignon. Honey is also a classic pairing, balancing the saltiness of the cheese.

9. How is blue cheese made?

The process begins with pasteurizing (or not, depending on the cheese style) high-quality milk and adding a starter culture to acidify it. Rennet is then added to coagulate the milk into curds. The curds are cut, drained, and formed into wheels or blocks. The Penicillium mold spores are either added to the milk or sprinkled on the curds. The cheese is then pierced with needles to allow air to circulate and encourage mold growth. Finally, the cheese is aged for several weeks or months, depending on the desired flavor and texture.

10. Can I make blue cheese at home?

Making blue cheese at home is a challenging but rewarding endeavor. It requires careful attention to detail, a controlled environment, and access to specific ingredients, including Penicillium mold spores. While it is possible, it’s generally recommended for experienced cheesemakers. There are many resources online that detail the process.

11. Are there any health risks associated with eating too much blue cheese?

While blue cheese offers nutritional benefits, it is also high in sodium and saturated fat. Consuming too much can contribute to high blood pressure and increased cholesterol levels. As with any food, moderation is key.

12. My blue cheese doesn’t have any blue veins. Is it safe to eat?

If your blue cheese lacks its characteristic blue veins, it may not have been properly inoculated with the Penicillium mold, or the mold growth may have been inhibited during the cheesemaking process. While it might still be safe to eat (assuming it smells and tastes normal and has been stored correctly), it won’t have the characteristic flavor and texture of blue cheese. It might be a completely different type of cheese entirely or a failed attempt at blue cheese. It’s best to return it to the store if you’re unsure.
