The world of cheese is diverse and fascinating, with over a thousand types available, each with its unique taste, texture, and aroma. Some cheeses are mild and creamy, while others are strong and pungent, often compared to the smell of feet. But what does it mean when cheese smells like feet? Is it a sign of spoilage, or is it just a characteristic of certain types of cheese? In this article, we will delve into the world of cheese and explore the reasons behind the infamous “foot smell” of some cheeses.
Understanding Cheese and Its Aroma
Cheese is a dairy product made from the proteins and fats in milk, often with the addition of bacteria, mold, or yeast. The type of milk used, the processing methods, and the aging time all contribute to the final product’s taste, texture, and aroma. Some cheeses, like mozzarella and feta, have a mild, slightly sweet smell, while others, like limburger and epoisses, are known for their strong, pungent aromas.
The Science Behind the Smell
The smell of cheese comes from the breakdown of its fats and proteins during the aging process. As cheese ages, bacteria and enzymes break down the molecules, releasing volatile compounds that give off a distinct aroma. In the case of cheeses that smell like feet, the main culprit is a group of bacteria called Brevibacterium linens. These bacteria are naturally present on human skin and are also used in the production of certain cheeses, such as limburger and taleggio.
Brevibacterium Linens: The Foot-Smelling Bacteria
Brevibacterium linens is a type of bacteria that thrives in warm, humid environments. It is commonly found on human skin, particularly between the toes, where it feeds on the sweat and dead skin cells. This bacteria is also used in the production of certain cheeses, where it helps to break down the fats and proteins, giving the cheese its characteristic smell and flavor. When Brevibacterium linens is present in cheese, it can produce compounds like isovaleric acid and 2-heptanone, which are responsible for the foot-like smell.
Types of Cheese That Smell Like Feet
While not all cheeses that smell like feet are made with Brevibacterium linens, this bacteria is often associated with the strongest and most pungent cheeses. Some examples of cheeses that are known for their foot-like smell include:
