Effects of different packaging conditions on quality of marinated chicken drumsticks stored at 4 C were investigated. Chicken drumsticks were marinated and packaged in vacuum, aerobic or modified atmospheres ( M 1: 0% O 2 + 70% CO 2 + 30% N 2 and M 2: 5% O 2 + 70% CO 2 + 25% N 2 ). Microbial (total viable count, lactic acid bacteria, yeasts and molds), chemical (thiobarbituric acid‐reactive substances, pH ) and sensory analyses (odor, color, texture, flavor, overall acceptability) were conducted during storage. Modified atmosphere packaging ( MAP ) decreased yeast and mold, lactic acid bacteria and total viable counts. Oxidation was inhibited by reduced O 2 and elevated CO 2 in the packages. There was no significant difference between the effects of modified atmosphere packages containing 0% O 2 ( M 1) and 5% O 2 ( M 2) on microbial counts and lipid oxidation. The overall quality of marinated chicken drumsticks was maintained best with MAP (both M 1 and M 2) during 15‐day refrigerated storage. Practical Applications Marinated chicken meat is a popular product among consumers. Developing methods to increase shelf life and overall safety/quality is required for its commercial production. In this study, use of modified atmosphere packaging ( MAP ) in marinated chicken drumsticks was studied for maintenance of quality and shelf‐life extension. An extended storage life of marinated chicken drumsticks was obtained through packaging under reduced O 2 (0–5%) plus elevated CO 2 (70%) concentrations. Our study has clearly shown that the MAP can maintain microbial, chemical and sensorial quality of marinated chicken drumsticks effectively during 15‐day refrigerated storage.
