Microwave sterilization is the result of the combined use of the thermal and biological effects of electromagnetic fields. The thermal effect of microwaves on bacteria is to cause the protein to change, causing the bacteria to lose nutrients, breed and survive in conditions of death. The biological effect of microwaves on bacteria is that the microwave electric field changes the potential distribution of the cell membrane cross-section, affects the electron and ion concentration around the cell membrane, thereby changing the permeability of the cell membrane, the bacteria are thus malnourished, can not normal metabolism, cell structure disorder, growth and development are inhibited And died. In addition, microwave energy enables bacteria to normally grow and stabilize genetically propagated nucleic and RNA DNAs, which are loosened, broken and recombined by several hydrogen bonds, thereby inducing genetic mutations, or chromosomal aberrations or even breaks.
