Effects of silver nanoparticles (AgNPs) and polymers on stored pests for improving the industry of packaging foodstuffs
The customers`s complaints of the contaminations of foodstuffs to stored pests such as insects, mold and toxic fungi polluted packagings after a short time of storing, were reasons to perform this research. Cereals are one of the most important stored products. In this study, we conducted batch experiments to assess the efficiency of silver nanoparticles incorporated into packaging polymer on the growth of fungi and insect pests. Sitotroga cerealella Ol. (Lep.: Gelechiidae) is tested because of economical importance of this pest in storing industry of packaged cereals. We applied AgNPs through the best packaging polymer (PP). The results showed that not only AgNPs could optimally omit toxic pathogens also but have a toxicant effect on insects. Thus, the property of antimicrobial and toxicity of AgNPs as a non-chemical pesticide investigated in the terms of storing cereals foods.
