Abstract [en]

Food packaging is tailored to keep food fresh by increasing shelf life and preventing microbial deterioration. However, traditional food packaging is commonly made from non-degradable polymers without antimicrobial properties and that pose an environmental threat if not disposed properly. To address this issue, here we describe the preparation of cellulose nanofibril (CNF) films and hydrogels with antimicrobial activity against common foodborne pathogens such as verotoxigenic E. coli, L. monocytogenes and S. Typhimurium. Furthermore, two grades of negatively charged CNFs with different fibrillation degrees were modified with ethyl lauroyl arginate (LAE), which is an antimicrobial agent. CNF films were able to bind LAE molecules up to a maximum concentration of 145–160 ppm. LAE–CNF biocomposite films exerted a bactericidal activity against a major foodborne pathogen present in ready-to-eat food (L. monocytogenes) even at 1% LAE. Our work describes a novel biopolymer-based strategy that overcomes the current hurdles with LAE incorporation into packaging materials, offering a green and antimicrobial alternative for packaging of ready-to-eat (RTE) meat products. .
