Salmon esh spoilage can be greatly reduced through the use of preservation methods, using natural products combined with low temperature and packaging. Microbiological and physicochemical characteristics of fresh salmon llets (Salmo salar), sprayed with an aromatic vinegar and stored in modi ed atmosphere packaging, were investigated. Fillets were kept at 4°C and sampled after 2 h and 3, 7 and 10 days. An untreated control group was used as well. Fish samples were analysed for microbiological (total viable count, Enterobacteriaceae, psychrotrophic microbial count, Pseudomonas spp.) and physicochemical (pH, colour, total volatile basic nitrogen, and biogenic amines) properties. Aromatic vinegar was found to bene cially contribute to the hygienic quality of the salmon, reducing microbial growth during storage and exerting a positive effect, mainly on psychrotrophic loads and Pseudomonas spp. The treatment had a positive effect on biogenic amine levels, showing lower values for histamine, putrescine, cadaverine, and tyramine.
