Starter cultures in cheese production are essential for the process of fermentation. They primarily consist of specific bacteria that ferment lactose, the sugar found in milk. When milk is incubated with these starter cultures, the bacteria metabolize lactose and produce lactic acid. This acidification is crucial for several reasons: it helps to develop the flavor and texture of the cheese, contributes to the preservation of the product by lowering the pH, and facilitates the coagulation of milk proteins, which is a critical step in cheese making.

The fermentation process initiated by these starter cultures also aids in the formation of the cheese’s unique characteristics, such as aroma and taste. This transformation is fundamental to the various styles of cheeses produced around the world, as different blends of bacteria can lead to distinct cheese profiles.

Understanding the role of starter cultures is vital for anyone involved in cheese production, as it lays the groundwork for the entire cheesemaking process.
