Popis:	Researchers have evaluated the effect of modified atmosphere packaging (MAP) on the shelf life of fish products. However, there is little published basis for recommended gas mixtures. Most studies have examined the effects of empirical evidence of gas mixes on particular species, but they cannot be used to predict the effect of different gas mixes on shelf life. Further, while the fish:gas ratio has been shown to be a key determinant of bacterial growth under MAP, most studies did not control this parameter. The aim of our research was to optimize gas mixes and fish:gas ratios for the MAP storage of king salmon. Flesh portions from defined fillet positions were placed on drip pads and boxed, giving a standardized nominal volume of 27.4 cm3 and an exposed surface area of 14.4 cm2. Each sample was placed in a foil barrier bag containing an oxygen absorber. Controlled volumes (0-100 cm3) of CO2 or 100 cm3 of a 40:60 mixture of CO2:N2 were then hand-injected through a septa. Bags were stored in melti...
