Is Cheese Cultures Real Food?

Approved

Cheese cultures are specific strains of beneficial bacteria or fungi intentionally added to milk to start the cheesemaking process. These microorganisms convert lactose (milk sugar) into lactic acid, which causes the milk to curdle, develops unique flavors, and contributes to the texture of the cheese.

Why it’s in your food

The manufacturer’s reason.

Food manufacturers use cheese cultures to initiate the fermentation of milk, which is essential for curd formation, developing the characteristic flavors and aromas, and achieving the desired texture and aging properties of different cheese types.

FAQ

Frequently asked questions.

Are cheese cultures harmful bacteria?▾
No, cheese cultures are beneficial, "good" bacteria (or sometimes fungi) that are safe for consumption. They are specifically chosen for their ability to transform milk into cheese and contribute desirable qualities, not to cause illness or spoilage.
Where do cheese cultures come from?▾
Traditionally, cultures were derived from starter whey or even naturally present in the environment. Today, they are carefully cultivated in laboratories to ensure consistency and specific characteristics for various cheese varieties, ensuring reliable results for cheesemakers.
Did a 1950s nonna use cheese cultures?▾
Yes, a nonna making cheese would implicitly use "cheese cultures" even if she didn't call them that. She might use a small amount of an old batch of cheese or whey from a previous cheesemaking day to start a new batch, relying on the live cultures within.
