Microwave sterilization is the result of the joint action of microwave thermal effect and biological effect,so that microwave can directly interact with bacteria,fast sterilization.
1.The thermal effect of microwave energy:under the action of a certain intensity of microwave field,bacteria will absorb microwave energy due to the polarization of molecules,thus making Protein and Physiologically active substance deforms and loses its biological activity.The thermal effect of microwave mainly plays the role of rapid warming and sterilization.
2.Non-thermal effect of microwave energy:the high frequency electric field changes the structure of polarized molecules,leading to protein and physiological active substances in the microbial body mutation and loss of vitality or death,in the sterilization of conventional physical sterilization has no special role.
