Effect of applying crust-freezing after skin-packaging on the natural microflora of Atlantic salmon (Salmo salar) during storage at low temperatures

نویسندگان

چکیده

The aim of the present study was to evaluate effect crust-freezing (CF) on fresh salmon fillets in skin-packaging during storage at −2.0°C. After CF, all treated samples and untreated controls were stored a refrigerated cabinet for 20 d. Sampling carried out days 0, 2, 6, 8, 10, 14 order analyse total volatile basic nitrogen (TVB-N) levels mesophilic psychrophilic viable counts (MVC PVC). Enterobacteriaceae (ENT), lactic acid bacteria (LAB), H 2 S-producing (SPB) Pseudomonas spp. (PSE). No significant differences TVB-N found between except those taken day where CF lower than controls. Our results suggest that ENT might be limiting microbial group determine end shelf-life. Thus, if this is used as an indicator acceptability, shelf-life can extended from 8 d when skin-packed then with CF.

Atlantic salmon – Salmo salar

Distribution Th e species’ range encompasses Europe, North America, and Green land (1) (Fig.1). Non-anadromous forms occur in Europe in a few land-locked locations in Norway and Sweden, and throughout the Neva/Lake Ladoga system and Karelia regions of Russia. In North America non-anadromous forms occurred throughout most of the species’ historical range, as far west as Lake Ontario, and remain ...

Effect of feeding rate on nutrient digestibility in Atlantic salmon, Salmo salar L.

A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s were all s...
