Abstract:

Prolonging the shelf life of food is one of the biggest challenges the food industry is facing, which when improved could decrease food decomposition, add value and will also help ease food sustainability concerns. This contribution presents a novel method using pattern forming templates to facilitate maximum anti-microbial functionality loading onto PVA substrates. The anti-microbial activity of a modified natural biopolymer chitosan and silver nanoparticles have been integrated into the PVA substrates and compared with respect to their activity against pure cultures of Staphylococcus aureus and Pseudomonas fluorescens. As evidenced by these results, it is proposed that silver nanoparticles in combination with modified chitosan have potential in improving the antimicrobial activity of packaging materials.
