“…Carvacrol (5-isopropyl-2-methylphenol) and thymol (2-isopropyl-5-methylphenol) are the major components of the essential oils of some species belonging to the Lamiaceae family including oregano, and these are phenolic compounds; isomers of monoterpenes exhibit signi cant antimicrobial activity in vitro [6,7].…”

“…Authors discussed the addition of antimicrobials and their influence in permeability to gases by changing their solubility or due to the creation of pinholes in the packaging structure depending on the chemical structure of the antimicrobial agent 101 . In addition, some modifications in crystallinity and glass transition temperatures were observed 19 . Scanning electron microscopy studies helped to explain structural modifications induced by the incorporation of additives to these polymer matrices, by detecting formation of pores, thereby influencing the tensile and gas barrier properties of the film 102 .…”

“…A presença de agentes tensoativos ou outros aditivos, utilizados para incorporar de forma eficiente o material no interior da matriz polimérica, pode também afetar a difusividade ou a solubilidade de permeantes [5] . A adição de carvacrol e timol ao polipropileno (PP), por exemplo, modificaram nos filmes a barreira ao oxigênio e as propriedades mecânicas [6] e a adição de glicerol melhorou a dispersão de amido de arroz em polietileno de baixa densidade (PEBD) e, consequentemente, as suas propriedades de tração [7] . Diante disso, é necessário mensurar as possíveis alterações geradas no que tange às propriedades físicas, mecânicas e de barreira [8] .…”
