چکیده
The development of active packaging for food storage containers is possible through impregnation natural extracts by supercritical CO2-assisted processes. challenge scCO2-impregnation to control the total loading and ensure that composition loaded extract may preserve properties crude extract. This study aimed at investigating clove (CE) in polycarbonate (PC) develop antibacterial packaging. A design experiments was applied evaluate influences temperature (35–60 °C) pressure (10–30 MPa) on (CL%) CL% ranged from 6.8 18.5%, highest reached 60 °C 10 MPa. impregnated dependent conditions, it differed extract, being richer eugenol (81.31–86.28% compared 70.06 extract). Differential scanning calorimetry showed a high plasticizing effect CE PC, led cracking PC surface. Due eugenol, which responsible CE, promising producing containers.
