Mono- and multilayer active films containing lysozyme as antimicrobial agent

摘要: Abstract Active packaging materials able to release antimicrobial compounds into foodstuff can be used in order avoid or slow down the bacterial growth during storage. In this work use of two techniques control chosen active compound (lysozyme) from a polymeric material is proposed: monolayer cross-linked PVOH film and multilayer structure made layers are developed studied. Lysozyme tests water were performed compare kinetics investigated films. Results suggest that by means both structures it possible rate at which lysozyme released film. The activity films was tested against suspension Micrococcus lysodeikticus. show incorporation does not lead loss enzyme. Industrial relevance increased gently processed foods requires an integral part preservation concept. Consequently additional aid shelf life extension. This paper concentrates on lysozyme, naturally occuring agent (eg. salvia, mothers milk, raw milk), A comperision mono- containing regarding their effectiveness M. lysodeikticus as target organism also performed. Both aims met leading controlled with no activity.
