Characterization and antimicrobial activity of a chitosan-selenium nanocomposite biosynthesized using <i>Posidonia oceanica</i>

Abstract

indicate the severe time-dependent destruction of bacterial cells within 8 h of exposure. The antioxidant potentiality of Cht/NG/SeNPs was the highest (91.36%), followed by NG/SeNPs (79.45%). The chicken fillets' coating with Cht, NG, NG/SeNPs, and Cht/NG/SeNPs resulted in a remarkable reduction in microbial group count and raised the sensorial attributes of coated fillets after 14 days of cold storage, with increased potentialities in the order: Cht/NG/SeNPs > NG/SeNPs > NG > Cht > control. The inventive, facile biosynthesis of Cht, NG, and SeNPs could provide effective antimicrobial and antioxidant nanocomposites for prospective applications in food biopreservation.
