Active packaging materials and intelligent packaging

Several active packaging materials and one intelligent packaging have been developed, studied and patented. In fact, the Group participates in four International patents, three of them in use by the companies participating in the development and the fourth one is now in proceeding between the University of Zaragoza and a multinational company. This has allowed to commercialize several active food packages, and the GUIA Group is internationally recognized as a leader group in the study and development of active packaging. The whole process has been carried out, from the technology design, study, optimization, technical evaluation, etc., to the last phase, which is industrial production and commercialization. These active packaging materials are antioxidant, antimicrobial or with added aroma.

  1. The active packaging developed to date don’t need direct contact between food and packaging to be efficient, which is an important difference with most of the active packaging prototypes proposed by others. Moreover, the active agents are authorized for direct contact with food and, therefore, can be used without legal problems and without requiring a specific dossier to ask for the acceptance to EFSA. This is a huge advantage versus other proposals.
  2. The new active materials are versatile. Each product needs a different protection. The designed active system allows to select the suitable active agent and the right concentration in the package according to the client (company) and product needs.
  3. The active agents are immobilized at room temperature, so there is no thermal degradation, compound loss or any alteration on the known composition of the food grade extract. This is again a constant performance in all the technologies explored and developed to produce the active or intelligent materials in the GUIA Research Group.
