Abstract

Composite film designed as new innovative transparent  edible film coating  grains was prepared by casting film-forming  colloidal emulsions covering maize  grains which was   based on chitosan and / or cinnamon, basil and dill  oils or extracts added to chitosan HMW (high molecular weight). Chitosan individual coating film succeeded as antibacterial and detoxifying agent, the reduction rate of E.coli growth  was the highest followed by Fumonisin B1 then aflatoxin B1production at the same(Minimum Inhibitory concentration( MIC). In case of Staphyllococcus aureus: Cinnamon extract at its both tested concentrations showed the best results (79.9 and 75.46 successively in inhibiting Staphyllococcus aureus growth) followed by chitosan at concentration 0.5% which realized (74.29%) growth inhibition. All tested EOs  individual coating films succeeded at their MICs  as antibacterial and detoxifying agents. The composite coating films are more effective  as antibacterial than detoxifying agents except the film composited of chitosan and cinnamon oil which was highly  succeeded as antibacterial and detoxifying agent in case of E.coli ,AflatoxinB1 and fumonisinB1the inhibition ratios were 94.145%, 91.217% and 90.01% respectively .Also, the composite film of chitosan and cinnamon extract inhibited E.coli, AflatoxinB1 and fumonisin B1 being: 97.943%,87.259% and 88.370% respectively. Synergistic Effects are more dominant in Bacterial growth inhibition than mycotoxins inhibition whereas, The antagonistic effect was often appeared in case of mycotoxins inhibition except the compound of chitosan and cinnamon oil, which gave the best results in the inhibition of mycotoxins.The composite film of chitosan and basil oil exhibited the highier inhibition ratio onE.coli growth being 98.418% . It is clear from the obtained results that the usage of composite film of chitosan and cinnamon oil can be used effectively to cover and preserve maize grains during storage.
