Does Feta Cheese Turn Blue? The Truth Behind The Moldy Myth
What To Know
- If the blue color is confined to the surface of the cheese and the cheese has no off-odors or flavors, it is likely safe to consume.
- If the blue color penetrates deep into the cheese or if the cheese has an unpleasant odor or taste, it is best to discard it.
- Store feta cheese in a sealed container in the refrigerator at a temperature of 40°F (4°C) or below.
Feta cheese, an integral part of Mediterranean cuisine, is known for its distinct flavor and crumbly texture. However, one question that often arises is whether feta cheese can turn blue. This blog post delves into this culinary enigma, exploring the factors that contribute to feta’s color changes and providing valuable insights into its safe consumption.
The Curious Case of Feta’s Bluish Hue
Contrary to popular belief, feta cheese does not typically turn blue. The characteristic white or slightly yellowish color of feta is due to the presence of lactic acid bacteria, which ferment the milk during the cheesemaking process. However, under certain circumstances, feta may develop a bluish tinge.
Factors Contributing to Feta’s Blue Color
1. Mold Growth: The most common reason for feta cheese turning blue is the growth of mold. Certain types of mold can produce blue or green pigments that stain the cheese’s surface. This mold is usually harmless and does not affect the taste or safety of the cheese.
2. Bacterial Contamination: In rare cases, feta cheese can become contaminated with bacteria that produce blue or green pigments. These bacteria are typically found in unpasteurized milk and can cause spoilage or food poisoning.
3. Acidic Environment: Feta cheese is made with sheep’s milk or a combination of sheep’s and goat’s milk, which has a higher acidity level than cow’s milk. Over time, the acidity of the cheese can weaken the protein bonds, causing the cheese to turn blue.
Safe Consumption of Blueish Feta
If you notice a bluish tinge on your feta cheese, it is important to assess whether it is caused by mold or bacterial contamination.
1. Mold: If the blue color is confined to the surface of the cheese and the cheese has no off-odors or flavors, it is likely safe to consume. Simply scrape off the moldy part and enjoy the rest of the cheese.
2. Bacterial Contamination: If the blue color penetrates deep into the cheese or if the cheese has an unpleasant odor or taste, it is best to discard it. Consuming contaminated feta can lead to food poisoning.
How to Prevent Feta from Turning Blue
To prevent feta cheese from turning blue, follow these tips:
1. Store Feta Properly: Store feta cheese in a sealed container in the refrigerator at a temperature of 40°F (4°C) or below.
2. Use Pasteurized Milk: Use feta cheese made with pasteurized milk to minimize the risk of bacterial contamination.
3. Consume Feta Fresh: Feta cheese has a relatively short shelf life. Consume it within 2-3 weeks of opening the package.
4. Avoid Acidic Environments: Keep feta cheese away from acidic foods or liquids, such as lemon juice or vinegar, which can weaken the protein bonds.
Other Factors Affecting Feta’s Color
In addition to the aforementioned factors, other aspects can also influence feta‘s color:
1. Aging: As feta cheese ages, it may develop a slightly darker color due to the natural breakdown of proteins.
2. Salt Content: The salt content of feta cheese can affect its color. Higher salt levels can result in a whiter appearance.
3. Fat Content: Feta cheese made with a higher fat content may have a creamier color than low-fat varieties.
Final Thoughts
While feta cheese does not typically turn blue, it is important to be aware of the factors that can contribute to this color change. By understanding the causes and taking appropriate precautions, you can enjoy feta cheese safely and appreciate its unique flavor and texture.
