Chees Culture

Cheese culture is a starter culture, a collection of microorganisms, typically bacteria, used to produce cheese. These microbes are responsible for the fermentation of lactose (milk sugar) into lactic acid, which is crucial for developing the characteristic flavor, texture, and aroma of cheese. They are grown in a controlled environment and then added to milk during the cheesemaking process.

Manufacturers add cheese cultures to milk to initiate the fermentation process that transforms milk into cheese. They contribute to flavor development, texture, and preservation. Cheese cultures are essential in the production of nearly all types of cheese, including cheddar, mozzarella, and Swiss, as well as in some dairy-based products like yogurt and sour cream.

In the U.S., cheese cultures are generally recognized as safe (GRAS) by the FDA when used as intended in food production. They are considered a natural part of the cheesemaking process. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated similar starter cultures, generally finding them safe for consumption. No significant health concerns are associated with the consumption of foods containing cheese cultures at typical intake levels.
