Antimicrobial and Physical–Mechanical Properties of Polyhydroxybutyrate Edible Films Containing Essential Oil Mixtures

In this study, three different combinations of essential oils (EO) of cinnamon, melaleuca and citronella were incorporated in polyhydroxybutyrate (PHB) films by conventional solution-casting method for food packaging applications. Although melaleuca and citronella EO films have been not demonstrated antimicrobial activity, they presented low UV transmission and high thermal stability. Films containing citronella and cinnamon EO or melaleuca and...
