摘要
综述了可见光LED灯和紫外LED灯的特性、灭菌机理和灭菌效果,同时介绍了在几种不同光敏剂辅助灭菌情况下可见光LED灯和紫外LED灯的灭菌效果,及所使用光敏剂的剂量、效果和作用的菌种。最后提出了LED光照灭菌技术存在的问题,并展望未来发展方向。
LED is a kind of green and environment-friendly cold light source,which has the advantages of non-toxicity,non-residue and wide application prospects in killing foodborne pathogenic bacteria in fruit and vegetable postharvest by using LED illumination technology.In this paper,the characteristics,sterilization mechanism and sterilization effect of visible and ultraviolet LED lamps were summarized.The sterilization effect of visible and ultraviolet LED lamps assisted by several different photosensitizers,as well as the dosage,effect and strains of the photosensitizers used werealso introduced.Finally,the existing problems and the future development direction of LED illumination sterilization technology were proposed.
