Unveiling the malodorous secret: why feta cheese has an awful smell
What To Know
- Feta wrapped in plastic wrap or stored in airtight containers will have a stronger odor than feta that is stored in breathable materials, such as cheesecloth or parchment paper.
- This is because the fat in the cheese acts as a barrier, preventing the release of volatile compounds.
- The odor of feta cheese can vary depending on the specific bacteria used in its production, the aging process, and the packaging.
Feta cheese, a staple in Mediterranean cuisine, is renowned for its strong, distinctive odor. While some find its aroma alluring, others are repelled by its pungent nature. The question of why feta cheese smells so bad has intrigued food enthusiasts and scientists alike. In this comprehensive guide, we will delve into the science behind feta’s unique odor, exploring the factors that contribute to its characteristic aroma.
The Role of Bacteria
The pungent smell of feta cheese is primarily attributed to the presence of bacteria. During the cheesemaking process, feta is inoculated with lactic acid bacteria (LAB), which ferment the lactose in the milk, producing lactic acid. This acidification process gives feta its distinctive sour flavor. However, certain strains of LAB also produce volatile compounds, such as propionic acid and butyric acid, which contribute to the cheese’s strong odor.
The Impact of Brine
After fermentation, feta is typically stored in a brine solution for several weeks or months. The brine helps to preserve the cheese and further develop its flavor. However, the brine also provides an environment where certain bacteria can thrive. These bacteria produce enzymes that break down proteins and fats in the cheese, releasing volatile compounds that contribute to its pungent aroma.
The Influence of Aging
As feta cheese ages, its odor becomes more pronounced. This is because the enzymes produced by bacteria continue to break down the cheese’s components, releasing additional volatile compounds. The longer the cheese is aged, the more intense its odor will become.
The Effect of Temperature
Temperature plays a significant role in the development of feta’s odor. When feta is stored at higher temperatures, the bacteria responsible for producing volatile compounds become more active. This leads to a more intense odor. Conversely, storing feta at lower temperatures will slow down the bacterial activity and reduce its odor.
The Influence of Packaging
The type of packaging used for feta cheese can also affect its odor. Feta wrapped in plastic wrap or stored in airtight containers will have a stronger odor than feta that is stored in breathable materials, such as cheesecloth or parchment paper. This is because the airtight environment prevents the release of volatile compounds, allowing them to accumulate in the cheese.
The Role of Fat Content
The fat content of feta cheese also influences its odor. Feta with a higher fat content will have a milder odor than feta with a lower fat content. This is because the fat in the cheese acts as a barrier, preventing the release of volatile compounds.
The Impact of Milk Source
The type of milk used to make feta cheese can also affect its odor. Feta made from sheep’s milk tends to have a stronger odor than feta made from cow’s milk or goat’s milk. This is because sheep’s milk has a higher concentration of certain volatile compounds, such as butyric acid.
Recommendations: Embracing the Complexity of Feta’s Aroma
While the pungent odor of feta cheese may be off-putting to some, it is an integral part of its unique flavor profile. The complex interplay of bacteria, brine, aging, temperature, packaging, fat content, and milk source contributes to the distinctive aroma that has made feta a beloved cheese around the world. Whether you find its odor alluring or repulsive, there is no denying the complexity and character that it brings to any culinary experience.
Popular Questions
Q: Why does feta from some brands smell stronger than others?
A: The odor of feta cheese can vary depending on the specific bacteria used in its production, the aging process, and the packaging. Different brands may use different strains of bacteria or aging techniques, resulting in varying levels of odor intensity.
Q: Is it safe to eat feta cheese that smells strong?
A: Generally, yes. The strong odor of feta cheese is typically not an indication of spoilage. However, if the cheese has an unusually sour or rancid smell, it may be best to discard it.
Q: How can I reduce the odor of feta cheese?
A: To reduce the odor of feta cheese, store it in an airtight container in the refrigerator. This will prevent the release of volatile compounds and keep the odor contained. You can also soak the cheese in cold water for several hours before consuming it.
