If butter is dairy, why doesn't it need to be refridgerated?!


Question:

If butter is dairy, why doesn't it need to be refridgerated?

My mother keeps the stick of butter on the counter under a lid at room tempurature all day, and always has. Why doesn't it become infected with bacteria and expire like other dairy products do?


Answers:

Butter is not a potentially hazardous food.
Butter is an emulsion where the water is tied up w/ the fat molecules and therefore unavailable.The fat itself does two other things:It prevents the microorganisms from getting any oxygen and since it is a fat it's also acidic . If you add the desiccating qualities of salt to all that you wind up with a low protein safe food product that doesn't require refrigeration.
