Question

Why can we boil water to make it safe to drink, but we can’t boil the “spoil” out of expired milk?

In: Chemistry

Answer 1

The reason is that it kills organisms that could infect you. The same is true for boiling spoiled milk but the difference is that chemicals other than water that were in the milk get changed into toxic compounds by these organisms that aren’t destroyed when boiled.
