Blue cheese, with its distinctive veining of blue or blue-green mold, has been a prized delicacy for centuries. The unique appearance and potent flavor of blue cheese have captivated the hearts and taste buds of many, but have you ever wondered what exactly that blue stuff is? In this article, we will delve into the world of blue cheese, exploring its history, production process, and most importantly, the science behind the blue mold that gives it its characteristic flavor and appearance.
A Brief History of Blue Cheese
Blue cheese has a rich and varied history that spans centuries. The origins of blue cheese are shrouded in mystery, but it is believed to have originated in the caves of Roquefort, France, where the unique combination of temperature, humidity, and microorganisms created the perfect environment for the growth of mold. The production of blue cheese soon spread throughout Europe, with different regions developing their own unique varieties, such as Gorgonzola in Italy and Stilton in England. Today, blue cheese is enjoyed all over the world, with its popularity showing no signs of waning.
The Production Process of Blue Cheese
The production of blue cheese involves a complex process that requires great skill and attention to detail. The process begins with the selection of high-quality milk, which is then heated and mixed with a starter culture that converts the milk sugar into lactic acid. The mixture is then left to curdle, and the curds are cut and drained to remove excess liquid. The curds are then molded into their distinctive shape and left to age. It is during this aging process that the magic happens, and the blue mold begins to grow.
The Role of Mold in Blue Cheese
The blue mold that gives blue cheese its characteristic veining is a type of fungus known as Penicillium roqueforti. This mold is introduced into the cheese during the production process, either by injecting it into the curds or by exposing the cheese to a moldy environment. The mold grows within the cheese, breaking down the fats and proteins and producing a range of compounds that contribute to the cheese’s distinctive flavor and aroma. The type and amount of mold that grows can vary depending on factors such as the type of milk used, the temperature and humidity of the environment, and the length of time the cheese is aged.
The Science Behind the Blue Stuff
So, what exactly is the blue stuff in blue cheese? The blue-green veining that runs through blue cheese is made up of a combination of mold and other compounds that are produced during the aging process. The mold itself is a type of fungus that grows in a network of fine, branching hyphae. As the mold grows, it breaks down the fats and proteins in the cheese, producing a range of compounds that contribute to the cheese’s flavor and aroma. These compounds include lipases, which break down the fats in the cheese, and proteases, which break down the proteins.
The Flavor and Aroma of Blue Cheese
The flavor and aroma of blue cheese are legendary, and are due in large part to the compounds produced by the mold. The mold produces a range of volatile compounds, including aldehydes and keto-acids, which contribute to the cheese’s pungent, slightly sweet flavor.
