A study was conducted to investigate the effect of oregano essential oil on the oxidative stability and color of raw and cooked chicken breast meats. Five treatments, including (1) control (none added); (2) 100 ppm oregano essential oil; (3) 300 ppm oregano essential oil; (4) 400 ppm oregano essential oil; and (5) 5 ppm butylated hydroxyanisole (BHA), were prepared with ground boneless, skinles...
Alginate films with different degrees of crosslinking obtained by internal and external gelation method and alginate films incorporated with oregano essential oil were prepared. The effect of mechanism of gelation and the incorporation of oregano essential oil on their optical, mechanical, antibacterial, microstructural and water vapor barrier properties were evaluated. The films subjected to e...
To investigate the effects of oregano essential oil and canola oil on digestibility, ruminal pH and ammonia and carcass quality of fattening Dalagh lambs, an experiment was conducted with 16 lambs with an average live weight of 25±2 kg in a completely randomized design with 4 treatments (Control diet based on barley grain and corn silage without canola oil and oregano essential oil, control die...
We developed wine formulations containing plant essential oils and oil compounds effective against foodborne pathogenic bacteria Escherichia coli O157:H7 and Salmonella enterica. HPLC was used to determine maximum solubility of antimicrobials in wines as well as amounts of antimicrobials extracted by wines from commercial oregano and thyme leaves. Activity of essential oils (cinnamon, lemongras...
The present study was conducted to characterize the in vitro antimicrobial activities of 3 essential oils [oregano, rosemary, and a commercial blend of essential oils (BEO)] against pathogenic and nonpathogenic bacteria and to evaluate their effects on broiler chicken performances. The chemical composition of the essential oils was determined using the gas chromatography interfaced with a mass ...
BACKGROUND Essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. So five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach Supella longipalpa. METHODS Evaluation was done against the 3rd and 4th instar nymphs using three bioassay methods; co...
The study was carried out to evaluate the dietary supplementation of oregano essential oil on performance and antimicrobial activity of broilers. A total of 250 day-old male were distributed in a completely randomized design divided into five groups with five replicates, each given a basal diet with avilamycin plus salinomycin (positive control) or a basal diet without added avilamycin and sali...
The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...
Aflatoxin B1 (AFB1) is a highly toxic and carcinogenic metabolite produced by Aspergillus species on food and agricultural commodities. Inhibitory effects of essential oils of Ageratum conyzoides (mentrasto) and Origanum vulgare (oregano) on the mycelial growth and aflatoxin B1 production by Aspergillus flavus have been studied previously in culture medium. The aim of this study was to evaluate...
Background: The aim of this study was to investigate the effects of chitosan coatings, oregano essential oil, and their combination on microbial quality of chicken fillet during 12 days in refrigerator temperature. Methods: Oregano oil was extracted by water distillation and then different concentrations of oregano oil (1% and 2%) were used for film preparation. Microbiological tests were carri...
