Microwave sterilization is the result of the thermal effect and the biological effect of microwave. The thermal effect of microwave on microorganisms is to denature the protein, leading to the death of microorganisms. The biological effect of microwave on microorganisms changes the electric field distribution of cell membrane section, which affects the concentration of electrons and ions around the cell membrane, thus changing the permeability of cell membrane Performance, so that microbial growth and development were inhibited and died. In addition, a strong enough microwave field can lead to biological DNA, RNA in the hydrogen bond relaxation, fracture and recombination. Thereby inducing genetic mutations. Since microwave sterilization utilizes the effects of thermal and nonthermal effects on biological damage, the sterilization temperature is lower than the conventional method, which facilitates the maintenance of the aroma of chrysanthemum beverages.
