Bio-composite Films Based on Alginate and Rice Husk Tar Microparticles Loaded with Eugenol for Active Packaging

This work focused on the valorization of tar derived from rice husk pyrolysis as a precursor matrices for encapsulation active principles. In this regard, development novel films based alginate and eugenol-loaded microparticles with suitable mechanical properties antibacterial activity was studied. Tar loaded eugenol were incorporated into sodium effect mechanical, thermal humidity resistance determined, well antimicrobial activity. Films different crosslinking degrees also prepared using CaCl2, controlled release profiles evaluated. Crosslinked exhibited improved properties, lower rate in water. The studies showed that present higher against Staphylococcus aureus. Alginate/eugenol-loaded composites an enhancement physical characteristics to be used packaging applications.
