Question

why does milk stay good inside the body warm but curdles when not refrigerated outside of the cow?

In: Biology

Answer 1

Milk spoils when unrefrigerated because bacteria consume the nutrients in it and replicate. When you drink milk, your body is the one breaking down and consuming the nutrients. The bacteria in your gut assist in this process, but the nutrients end up in your bloodstream and poop instead of being used to grow the bacterial colony. It doesn’t stay “milk” for long after you consume it, it becomes half-digested stomach contents and eventually poop as a result of being digested.
