-
It was evaluated the effect of chitosan different molecular in the elaboration of antimicrobial films with essential oils and functional extracts.
The antimicrobial activity was evaluated by determination of minimum inhibitory concentration and minimum bactericidal concentration.
The antibacterial effect of the edible films prepared was further evaluated by zone of growth inhibition against the same foodborne pathogens.
-
The films of low molecular weight chitosan with 2% of AE of clove and clove E7 have antimicrobial activity against most strains tested.
-
Antimicrobial films elaborated can be considered as active packaging and for the prevention and control of pathogenic microorganisms in food.
