Abstract

The antioxidant and antimicrobial properties of Zataria multiflora and Iranian and European Cumin were evaluated, first as pure extracts and later as active agents incorporated in paper, manufactured at laboratory scale as an active packaging material. Two different procedures were used for quantifying the antioxidant properties and microbiological studies versus Staphylococcus aureus, Listeria innocua, Pseudomonas sp., Salmonella enterica subsp. enterica and Escherichia coli were carried out. All bacteria were inhibited when exposed to the atmosphere generated from 4 to 6 (w/w) of Zataria essential oil in the active coating. Zataria showed the best antioxidant properties. The compounds responsible for the antimicrobial and antioxidant properties are analyzed and discussed. © 2014 Elsevier Ltd.
