Milk quality assurance technology: Pasteurization

And the byproducts of the microbes' consumption are compounds that taste and smell nasty.But there's a bigger problem.Raw milk can carry microbes that are the sources of deadly diseases,so in order to kill as many of those microbes as possible,and keep milk fresh longer,we use a technique called pasteurization.One version of this process involves exposing milk to about 30 seconds of high heat.
