| Abstract: | Modified atmosphere packaging using CO, was demonstrated to be effective in retarding the growth of microorganisms during storage of fresh fish from the Gulf of Mexico. At 4°C, there was at least a log difference in bacterial counts at 2, 4, and 6 days between fish stored in CO2 as compared to control fish stored without CO2. While the CO2 atmosphere was shown to inhibit the growth of common spoilage types of bacteria such as gram-negative rods (Pseudomonas), stimulation of gram-positive bacteria such asLacto-bacillus was also demonstrated. Fish stored at 4°C for 2–8 days in a modified atmosphere containing CO2 had lower TVN values than fish stored at the same temperature without CO2. The results indicate that an extension of the shelf-life of fresh fish can be obtained by packaging and storing the fish in a CO2 atmosphere. |
