Abstract
Monoethyl fumarate (mef), bovine serum albumin (bsa), abietic acid (ab), morphine (mrp), aspirin (asp), indole (ind), and lysozyme (lysz) functionalized poly vinyl chloride (PVC) samples were synthesized for possible application of the active food packaging materials. Antioxidant properties of the new PVC-derivatives were determined by inhibition of the autoxidation of linseed oil via following its oligomerization. For this purpose, linseed oil was laid on the obtained PVC derivatives and exposed to air oxygen. Oligomerization of autoxidized linseed oil was measured by the increase in viscosity using an Ubbelohde viscometer. Because of the inhibition of autoxidation, oligomerization of the linseed oil lasted longer. The autoxidation time of linseed oil was delayed on the PVC-natural compound derivatives. Considering the delaying time, the antioxidant effect on the linseed oil was in the following order: PVC-abietic acid (29 days) > PVC-bovine serum albumin (24 days) > PVC-indole (21 days) > PVC-lysozyme (20 days) > PVC-mono ethyl fumarate (16 days); PVC-aspirin (16 days); Petri dish (16 days) > PVC-morphine (15 days) > PVC-control (14 days). The antibacterial activities of the novel PVC derivatives were assessed against Escherichia coli and Staphylococcus aureus bacteria. PVC-aspirin and -indole membranes showed significant antibacterial effect against E. coli and S. aureus. Also, according to flow cytometer results, a live cell percent above 90% was obtained for PVC derivative membranes.
