Nowadays, distribution and microorganism resistance against antimicrobial compounds
have caused crucial food safety problems. Hence, nanotechnology and zeolite are recognized as new
approaches to manage this problem due to their inherent antimicrobial activity. Different studies have
confirmed antimicrobial effects of Nano particles (NPs) (metal and metal oxide) and zeolite, by using
various techniques to determine antimicrobial mechanism. This review includes an overview of research
with the results of studies about antimicrobial mechanisms of nanoparticles and zeolite. Many
researches have shown that type, particle size and shape of NPs and zeolite are important factors showing
antimicrobial effectiveness. The use of NPs and zeolite as antimicrobial components especially in
food technology and medical application can be considered as prominent strategies to overcome pathogenic
microorganisms. Nevertheless, further studies are required to minimize the possible toxicity of
NPs in order to apply suitable alternatives for disinfectants and antibacterial agents in food applications.
