The effect of modified atmosphere on chemical, textural, microbiological and sensory quality of seer fish (Scomberomorus commerson) steaks stored at 0-2C for 23 days was studied. Of the chemical indicators of spoilage, significant differences (P < 0.05) in trimethylamine and thiobarbituric acid values were observed between air- and modified atmosphere (MA)-packaged samples. Seer fish under MA was acceptable on the basis of sensory and microbiological parameters even though the K value was more than 95%, indicating that K value was not a suitable quality indicator. Based on the inosine to hypoxanthine observed in this trial, seer fish was classified as hypoxanthine producers. Bacterial counts of air-packaged seer fish were always higher than MA-packaged samples. Based on sensory score and microbiological data, the shelf life of fish steaks packaged in MA 21 days whereas air-stored samples had a shelf life of 12 days only.
