Betanin immobilized LDPE as antimicrobial food wrapper

LWT, 2017
Abstract Betanin was immobilized on LDPE by UV cross-linking and tested as food wrapper. The attachment of live Staphylococcus aureu and Escherichia coli bacterial colonies were 2.3 and 1.5 times less respectively on this film when compared to bare polymer. The corresponding reduction in the carbohydrate in the biofilm formed on the surface was 1.
