Does Milk Have a Smell?
Fresh milk typically has little to no noticeable odor. However, a strong or unpleasant smell is a clear indication that the milk has spoiled and should be discarded. This is a reliable way to assess the quality of milk.
Several factors influence the smell of milk:
-
Freshness: Fresh milk possesses a very faint, almost imperceptible scent. As milk spoils, bacteria multiply, producing acids that create sour or unpleasant smells. Source: Using Our Senses to Troubleshoot Milk Quality Issues

Type of Milk: The type of milk (e.g., cow's milk, breast milk) and its processing can affect its smell. For example, breast milk with high lipase can develop a soapy odor, though this is generally harmless. Source: Factors Affecting Breast Milk Taste and Smell | Medela
