Abstract
The addition of sachets or pads containing volatile antimicrobial agents into packages has been the most successful commercial application of antimicrobials to packaging. In this study, the effect of oregano (Origanum onites) essential oil on the extension of shelf life of overwrap packed fresh chicken drumsticks was investigated. Meat exudate absorbent pads were sprayed with 5 mL of oregano essential oil at a concentration of 1.5% in distillate water. Sampling was carried out at 0, 3, 5, and 7 d of the refrigerated storage. Total viable count, psychrotrophs, pseudomonads, members of the family Enterobacteriaceae, yeasts, and lactic acid bacteria were enumerated. Physicochemical analysis and sensorial evaluation were also conducted. The shelf life of fresh chicken drumsticks was approximately 3 d. Oregano essential oil extended product shelf life by approximately 2 d. Thus, incorporation of essential oils to absorbent pads may have supplementary applications in food packaging.
