2.1.5. Active packaging
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. (Sabi~nanigo, 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.
