Evaluation of edible chitosan coatings on shelf life and control of Listeria monocytogenes of meat and ready-to-eat meat products

Papadopoulos Panagiotis 2019

Chitosan is a natural, nontoxic, biodegradable biopolymer which derives by the deacetylation of chitin, a main component of the shells of crustaceans such shrimp, crab and crawfish. Chitosan as well as it’s oligomers, receive considerable attention due to their antimicrobial, antitumor and hypocholesterolemic abilities. Chitosan based edible coating and films, incorporated or not with other antimicrobial agents (essential oils, lauric alginate, ester, allyl -isothiocynate, nisin ,etc) seem to be promising for their application in food preservation. The inhibitory effect and delay of L.monocytogenes growth by chitosan has reported in several meat products, both raw and ready-to -eat (RTE)

In our laboratory, studies have been conducted related to the effect of edible chitosan coating coating on the shelf of raw meat products (sliced raw bovine meat and chicken breast) as well as RTE, and on the of L.monocytogenes growth in RTE bovine meat balls stored aerobically at 5°C.
