The selected active agents were incorporated on two different substrates: paper and polymeric film. Paper was spiked with the active agents, dried and directly used as active label without direct contact with the target food. The polymeric films were manufactured and supplied by Artibal S.A. (Sabiñánigo, Spain). Active films consisted of polyethylene terephthalate coated with an active coating containing the antioxidant agent. The coating components are protected by the patent EP1477519 A1. Table 1 lists the active packages studied herein
