Microwave sterilization mechanism
    Microwave and interaction of organisms is an extremely complex process. It is when the organism by microwave radiation , the microwave transmission organism is absorbed integrated biological effects arising from the results summarized in the following aspects.
    A thermal effect
    Refers to the temperature rise and thermal effects arising therefrom role in physiological and pathological changes . Under the action of the microwave in vivo substances, such as microbial cells under the effect of the microwave field , the molecules are polarized and make high-frequency oscillation , thermal effects , the temperature rises . Rapid temperature rise to higher-order structure of proteins changes, so the loss of biological activity, the cell death or serious interference can not reproduce , so as to achieve the purpose of sterilization .
    Two non-thermal effects
    Non-thermal effect refers to the action of the electromagnetic organism , in addition to thermal effects outside the body , can have a strong biological response , to occur in vivo physiological , biochemical, and functional changes . Ordering microwave biological change and movement of aggregate state , and the microwave field induced ion flow will affect the state of charge near the cell membrane and distribution of the barrier function resulting membrane damage , resulting in membrane function disorder, which interfere with or destroy the cell the normal metabolic function, leading to inhibition of bacterial growth , stopping or death. From the biochemical point of view, normal growth and reproduction of bacteria nucleic acid (RNA) and deoxyribonucleic acid
(DNA) is formed by connecting a number of hydrogen bonds tightly curled macromolecules , microwave causes hydrogen relaxation , fracture and restructuring , and induce genetic or chromosomal aberrations, or even broken , thus affecting its biological activity change , delay or interruption of cell stable inheritance and proliferation.
