Abstract

Abstract
Seafood is valuable protein sources for human being and acts important role in a healthy diet. Due to probability of fish contamination, from catch time to consume time with different microorganisms, there’s different technics to prevent fish spoilage. The present study purposed to investigate the effect of encapsulated thyme (Zataria multiflora Boiss) extract and chitosan to inhibit L. monocytogenes growth in filleted rainbow trout meat during refrigerated storage.The filleted samples were inoculated by1 ×103cfu/g of L. monocytogenes. Then samples exposed to 0.8 % and 1.2% thyme extract and 0.15 % and 0.25% v/w% chitosan nano particles and control group in five tratments. All treatments were kept for 16 days at refrigerator temperature. Every 4 days amount of Total viable count (TVC), Psychro trophic count (PTC) and Listeria monocytogenes counts measured. Least TVC, PTC and EBC in final experiment day observed in 0.25% chitosan treatment (p<0.05). Result indicated by passing time the efficiency of preservatives against L. monocytogeneswill be decrease and use of chitosan will cause better inhibition of L. monocytogenes in refrigeration condition.Use of chitosan and thyme extract can significantly prevent the growth of Listeria monocytogenes  also chitosan is more effective in Listeria monocytogenes prohibition.
