The present study was conducted to preserve the microbial quality of chicken meat fillets during storage time by
using sodiumalginate active coating solutions incorporated with different natural antimicrobials including nisin,
Cinnamomum zeylanicum (cinnamon), and rosemary essential oils (EOs) which were added individually and in
combination. The samples were stored in refrigeration condition for 15 days and were analyzed for total viable
count, Enterobacteriaceae count, lactic acid bacteria count, Pseudomonas spp. count, psychrotrophic count, and
yeast and mold count, as well as fate of inoculated Listeria monocytogenes at 3-day intervals. Results indicated
that values of tested microbial indicators in all samples increased during storage. Antimicrobial agents, when
used in combination, had stronger effect in preserving the microbial quality of chicken meat samples rather
than their individual use and the strongest effectwas observed in samples coatedwith alginate solution containing
both cinnamon and rosemary EOs (CEO + REO). However, all treatments significantly inhibited microbial
growth when compared to the control (P b 0.05). Therefore, based on the results of this study, application of alginate
coating solutions containing nisin, cinnamon, and rosemary EOs as natural preservatives is recommended
in meat products especially in chicken meats.
