Active cellulose-based packaging materials were prepared by binding lactoferrin to paper modified with anionic polyelectrolytes. About 63% of the protein added in the slurry was present in the finished paper, corresponding to about 0.28 mg protein per cm2 of the glassine paper produced. The efficacy of the activated materials was assessed by microbiological trials, employing targets bacteria considered as spoilage and/or pathogens in food products. Lactoferrin-activated paper evidenced its efficacy against growing cells of E. coli and L. innocua, with a maximum of 0.3 and 1.3 log cycles reduction of the final population, respectively. These results can be considered a promising starting point and will be the focus of further research, aimed at developing innovative cellulose-based active food packaging. [ABSTRACT FROM AUTHOR]
