Antimicrobial activity of chitosan coatings and films against Listeria monocytogenes on black radish
Abstract
The antibacterial activity of chitosan coatings prepared with acetic or lactic acid, as well as of composite chitosan-gelatin films prepared with essential oils, was evaluated in fresh shredded black radish samples inoculated with Listeria monocytogenes ATCC 19115 and L. monocytogenes ATCC 19112 during seven days of storage at 4 degrees C. The chitosan coating prepared with acetic acid showed the most effective antibacterial activity. All tested formulations of chitosan films exhibited strong antimicrobial activity on the growth of L. monocytogenes on black radish, although a higher inhibition of pathogens was achieved at higher concentrations of chitosan. The antimicrobial effect of chitosan films was even more pronounced with the addition of essential oils. Chitosan-gelatin films with thyme essential oils showed the most effective antimicrobial activity. A reduction of 2.4 log(10) CFU/g for L. monocytogenes ATCC 19115 and 2.1 log(10) CFU/g for L. monocytogenes ATCC 19112 was achieved... in the presence of 1% chitosan film containing 0.2% of thyme essential oil after 24 h of storage.
