| Antimicrobial active packaging not only protects food against environmental conditions, but also can inhibit or reduce microorganisms growth and increase its shelf life. Because of higher surface to volume ratio, antimicrobial nanostructures are more effective against microorganisms. Amongst these antimicrobial nanostructures, nanosilver has extraordinary antimicrobial activity on abroad spectrum of microorganisms and during recent years it has attached many attentions.
All the scientific articles which were published between 2000 and 2012 in Science Direct, Google scholar, Springer and Wiley databases about antimicrobial effects of silver nanoparticles on packaging of food products were reviewed.
Comparing with natural components of silver, silver in nano scale has tremendous antibacterial effects and can be used in combination with wide range of packaging materials. Silver nano particles are effective against wide spectrum of gram positive and gram negative bacteria. The mechanism in which silver nano particles confer their antimicrobial effects, is mainly attributed to the oxidative stress and this effect can be achieved through both direct contact and release from packaging matrix.
Silver nano particles have been used successfully in food packaging or food contact materials. They significantly reduce the growth of food spoilage and pathogenic microorganisms.
