Development and Characterization of Antimicrobial Packaging Films
Author(s): Zinash Assefa and Shimelis AdmassuZinash Assefa and Shimelis Admassu
The purpose of this work was to develop and study the effect of bioactive component towards the inhibition of microbial activities of films; aiming to assess their performance in employing for antimicrobial packaging film. In order to achieve appropriate inhibition effect of the antimicrobial agent, the structure of the films was changed from a highly asymmetric and porous to the dense by the modulation of the composition of the initial casting solution. The results on inhibition effect of starch-based films prepared from 90-100% (w/w) starch and 0-10% (w/w) bioactive component (saponin) revealed antimicrobial activity in a growth of bacteria (Escherichia coli, Salmonella typhi and Entrobacter erogenous). An increase in saponins concentration in the casting solution decreased the growth of microorganisms and the inhibition activities of the films increased. Results on moisture content.. View More»
