Which is better pasteurization or sterilization?
Sterilization is intended to destroy all germs and particularly pathogenic bacteria in their vegetative and sporulated form. The moderate heat treatment of pasteurization allows the destruction of pathogenic microorganisms present in their vegetative form, and a large number of spoilage microorganisms.
What is the main difference between pasteurization and sterilization?
The difference between sterilization and pasteurization is that sterilization is a method used to kill all microorganisms and their spores, whereas pasteurization is the method that is used to kill only the vegetative form of the bacteria where the spores survive.
