Alkynyl silver modified chitosan and its potential applications in food area
نویسندگان
چکیده
Chitosan was modified by substituting alkynyl silver on chitosan (Ag-CS) through a two-step chemical modification to form novel antimicrobial coating material. The physicochemical property, activity, cytotoxicity, and potential food applications of Ag-CS were systematically investigated. presented smooth sheet structure, demonstrated stronger effects than either acetate (AgOAc) or nitrate (AgNO3) against both Gram positive negative bacteria strains. also controlled release Ag for over 5 days, whereas AgOAc AgNO3 infused released 90 % within 4 h. shrimps significantly extended their shelf-life. Overall, our results revealed that the newly developed material possesses strong efficacies with sustained its ability slow down spoilage rate indicates in improvement quality shelf life.
