Amirhossein Goli Assistant Professor, Food Science and Technology, Esfahan University of Technology Journal Article 2014 11 23 Hydroxypropylmethylcellulose (HPMC) presents excellent film forming properties but, HPMC film for hydrophobic nature showed poor moisture barrier properties. In this study, water vapor (WVP)/oxygen permeability (OP), mechanical/optical properties and the antioxidant activities of HPMC films containing oregano essential oil (EO) against soybean oil oxidation were evaluated by measuring the peroxide value (PV). The antioxidant activity (AA) of EO was investigated using DPPH free radical scavenging, β-carotene/linoleic acid bleaching and reducing power methods. Results of AA in different model systems showed that, EO has acceptable AA in compared with BHT. Addition of EO into HPMC film, led to a significant decrease (P Hydroxypropylmethylcellulose (HPMC) presents excellent film forming properties but, HPMC film for hydrophobic nature showed poor moisture barrier properties.
