Notes:
The nutritional quality of proteins from fillets of fresh rockfish (Sebastes spp) stored in air or in a modified atmosphere (MA) of 80% CO2 and 20% O2 at 4°C was evaluated by the Computed Protein Efficiency Ratio (C-PER) method. This procedure involves determination of in vitro digestibility and the amino acid composition of the samples prior to computation of the C-PER. Casein was used as a standard. Both air-held and MA-held fish showed similar amino acid profiles, but the air-held fish showed lower in vitro digestibility. The C-PER values of both types of samples were higher than the C-PER of 2.50 for standard casein. These results suggest that storage of fish in a modified atmosphere of 80% CO2 and 20% O2 does not result in deterioration in the nutritional quality of the fish proteins.
