微波杀菌机理与生物学效应

Mechanisms of microwave inactivation and biological effects

微波是电磁波谱的一部分,它们的频率范围在300MHz～300GHz,相对应的波长为1m～1mm。微波作为一种新型的加热技术,在许多领域得到广泛的应用。由于微波与生物体的相互作用是一个极其复杂的过程,关于微波杀菌的热效应之外是否存在非热效应一直存在争议,因此,微波杀菌的机理还不是很透彻。本文重点综述了微波的生物学效应,以期完善微波杀菌机理。

Microwaves are part of the electromagnetic spectrum and are considered to be that radiation ranging in frequency from 300 million cycles per second （300MHz） to 300 billion cycles per second （300GHz）, which correspond to a wavelength range of 1 m down to t mm.As a newly-developing heat technology, microwave has been used widely in many areas.The interactivity between microwave and biosystems are very complex and the bioeffects of microwaves are controversial, so the mechanisms of microwave inactivation have not been fully understood.The bioeffects of microwaves were detailedly summarized in this paper,in order to offer a supplement to the mechanisms of microwave inactivation.
