In order to prepare the active films, ordinary household plastic for wrapping foods, a low density polyethylene of 12 lm of thickness, was cut into foils of the size: 30 22 cm = 660 cm2
The obtained plastic foils were spread and the necessary amount of rosemary extract solution to reach 1000 ppm (mg rosemary extract/kg meat) was poured onto each one. Afterwards, it was well
distributed over the surface using a brush and left overnight for ethanol evaporation. The antioxidant active film had 0.45 mg rosemary extract/cm2
