Bacterium, like any biological cell, is a condensed medium composed of complex compounds such as water, proteins, nucleic acids, carbohydrates, fats, and inorganics. Among them, water is the main component of biological cells, with a content of 75-85 %. All kinds of physiological activities need water to participate in, and the growth and reproduction of bacteria, the absorption of various nutrients through the cell membrane diffusion, penetration and adsorption to complete. 

The biological effect of microwave on cells 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, causing cell malnutrition, abnormal metabolism, cell structure and function disorder, growth and development are suppressed and died.

Under the action of a certain intensity of microwave field, insects and bacteria in food will also absorb microwave energy to heat up due to molecular polarization relaxation. Because they are condensed matter media, the strong intermolecular force aggravates the conversion of microwave energy to thermal energy. Therefore, the protein in the body is subjected to both non-polar thermal motion and polar rotation, so that its spatial structure changes or destroys and its protein is denatured. After protein denaturation, its solubility, viscosity, expansibility, permeability and stability will change significantly, and lose biological activity. 

Compared with high temperature sterilization, microwave sterilization has the following characteristics : 1 low sterilization temperature and fast sterilization speed ; 2 sterilization of the whole body inside and outside the object ; 3 no damage to the original nutritional composition, color, taste and natural flavor of the object. 

It is mainly used for powder, granular, flake or colloidal food, medicine, condiments and other products that need to be sterilized.
