What's the difference between light wave disinfection and microwave disinfection?

1, microwave is the infiltration heating of food by water, and the heat is relatively uniform; On the other hand, light waves "bake" food from outside to inside. On the contrary, light waves are more likely to burn food and cause nutrient loss.

2. Light wave disinfection is not suitable for high temperature resistant tableware. In addition, the surface temperature of non-irradiated tableware is low, the thermal uniformity is poor, and the sterilization effect is poor. Microwave can't penetrate metal, so microwave disinfection is not suitable for metal tableware disinfection.

Sterilization mechanism

Microwave sterilization is the result of interaction between thermal effect of electromagnetic field and biological effect. The thermal effect of microwave on bacteria is to change the protein, so that bacteria lose nutrition, reproduction and living conditions and die. The biological effect of microwave on bacteria is that microwave electric field changes the potential distribution of cell membrane cross section, affects the concentration of electrons and ions around cell membrane, and thus changes the permeability of cell membrane.

It leads to bacterial malnutrition, abnormal metabolism, disorder of cell structure and function, inhibition of growth and development and death. In addition, microwave can make bacteria grow normally and reproduce stably. Ribonucleic acid [RNA] and deoxyribonucleic acid [DNA] relax, break and recombine through several hydrogen bonds, thus inducing gene mutation or chromosome aberration or even break.
