Application of essential oil of Gum, polypropylene and silica nanoparticles as a new milk packaging.

The aim of current study was to investigate the antimicrobial effect of gum essential oil of (wild pistachio) tree (GEO) and design a new film based on polypropylene polymer coated with silica nanoparticles and GEO. The antimicrobial activity of the packaging film was evaluated with or without milk on , , , and during 35 days. The results showed that GEO has significant antibacterial properties.
