Then, the samples were transferred to the refrigerator to check the viability of probiotics and count <i>L. monocytogenes</i> on days 0, 3, 6, 9, 12, and 15. </span><br> <b><span style="color:black">Results:</span></b><span style="color:black"> The results of the viability showed a significant difference between the control samples and those coated with<i> L. rhamnosus </i>and <i>B. bifidum</i> (<i>P </i>< 0.05). Regarding the control of <i>L. monocytogenes</i> growth, the results indicated a significant inhibitory effect on this bacterium compared to the control group (<i>P</i> < 0.05). Moreover, the sensory evaluation characteristics of chicken fillets showed that the edible coating did not have an adverse effect on sensory properties, and the product was preserved. </span><br> <b><span style="color:black">Conclusion: </span></b><span style="color:black">The gelatin edible coating can act as a suitable matrix for a combination of probiotic bacteria in foods to control pathogens.</span></span></span></span></div> Probiotic, Edible coating, Listeria monocytogenes, Chicken fillet, 182 187 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-646-1&slc_lang=en&sid=1 Mehrdad Rezaeian mehrdaderezaeian@gmail.com 100319475328460015593 100319475328460015593 No Department of Health, School of Medicine, AJA University of Medical Sciences, Tehran, Iran.
