What Acid is Formed When Milk Sours?

When milk sours, the acid that is formed is lactic acid. Lactic acid is produced by bacteria that are present in the milk. These bacteria feed on the sugars in the milk, converting them into lactic acid through a process called fermentation.

Lactic acid is responsible for the sour taste and smell of sour milk. It is a weak acid that is also found in other dairy products such as yogurt and cheese. In addition to giving sour milk its characteristic taste, lactic acid also helps to preserve the milk by lowering its pH level and inhibiting the growth of harmful bacteria.

If you have ever left a carton of milk out of the refrigerator for too long, you may have noticed that it begins to sour. This is because the bacteria in the milk have had the opportunity to multiply and produce lactic acid. While sour milk is not suitable for drinking, it can still be used in cooking and baking as the acid can help to tenderize meat and improve the texture of baked goods.
