Not AvailableThe 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.Not Availabl

Not AvailableA study to evaluate the influence of potassium sorbate combined with modified atmosphere packaging (MAP) at 2C on the shelf-life extension of seer fish (Scomberomorus commerson) steaks was made. The shelf life of 12 days in air pack was extended by 10 and 18 days in MAP and modified-atmosphere-packed seer fish pretreated with potassium sorbate, respectively. K value was not a suitable predictor of shelf life for seer fish. Potassium sorbate treatment showed further inhibition of total aerobic mesophilic count while sulfite reducing clostridial counts were 1 log cfu/g in all the packs after day 12 of storage. Potassium sorbate treated MAP samples showed higher sensory score on day 25 than those observed for MAP (P < 0.05) and CMAP steaks. Significant extension (P < 0.05) in shelf life was noticed due to MAP and treating samples with potassium sorbate.Not Availabl
