For this purpose, ambient air packaging and modified atmosphere packaging (MAP) with gas mixtures of CO, CO2 and N2 (in a ratio of 0.4/30/69.6); CO2, N2 and O2 (in the ratios of 40/30/30, 50/30/20, and 60/30/10); and CO2 and N2 (in a ratio of 40/60) were applied. Salmon fillets were analyzed for biogenic amine contents and chemical, microbiological and sensorial properties during 27-day cold storage. The study results indicate that salmon fillets stored in cold storage undergo a deterioration process depending on storage time and packaging conditions. The thiobarbituric acid reactive substances, total volatile basic nitrogen and trimethylamine nitrogen values, and biogenic amine levels were lower in CO-MAP and 60% CO2-MAP compared to the air-packaged samples in extended storage period. Furthermore, 1.5-2 log bacterial inhibition was recorded in CO-MAP and 60% CO2-MAP, which allowed the products to be consumed up to day 21. However, the shelf-life of air-packaged salmon was limited to one week due to the signs of deterioration. In conclusion, modified atmosphere packaging with 0.4% CO and 60% CO2 significantly extended the shelf-life of cold-stored salmon fillets by maintaining quality characteristics of the products. These alternative gas concentrations can also be effective in the preservation of other fatty fish species under cold storage.eninfo:eu-repo/semantics/openAccessAtlantic salmoncold storagepackagingquality parameterssensory attributesArticle10.31883/pjfns/1946502-s2.0-852115052993394Q232374WOS:001372509600002Q3
