DETERMINATION OF ANTIMICROBIAL ACTIVITY OF PLA/SILICA BIONANOCOMPOSITES FOR FOOD PACKAGING APPLICATION

Pasteurized refrigerated (fresh) juices are the most accepted among commercial juices, however the stability of these products depends greatly on limiting recontamination by preserving the cold chain and restricting the duration of refrigerated storage after the package is opened. The use of sulphites can reduce this recontamination, however allergic disorders associated with this compound suggest that alternatives need to be used. In this work we propose the use of pimaricin-loaded poly(N-isopropylacrylamide) nanohydrogels, which can act as a protector against pimaricin degradation while allowing its controlled release.
