PLA films containing oregano essential oil for food packaging

Researchers at the Universidad de Sevilla in Spain developed polylactic acid (PLA) films containing different concentrations of essential oil from oregano (OEO). The effectiveness of this new active packaging was checked for use in ready-to-eat salads.
A plasticising effect was observed when OEO was incorporated in PLA films. The rest of the mechanical and physical properties of the developed films did not show much change when OEO was included in the films. An antioxidant effect was recorded only for films containing the highest percentages of the active agent (5% and 10%). An article about the research is published in Food Additives & Contaminants: Part A.
