Abstract/Description: | European Union insists on sensory grading of fish species prior to export and competent authority of each exporting nation need to have a sensory scheme for grading aquatic species based on freshness. The objective of the study was to evaluate the quality based on sensory grading of three species namely, Scomberomorus commerson, Etroplus suratensis and Sardinella longiceps during chilled storage as per EU scheme. Photographic evidence during the stages of progressive loss of freshness was documented, which was supported by evaluation of incremental changes in biochemical, microbiological and gradual loss of sensory characteristics. Grading to E, A and B was done based on visual observations of eyes, gills, operculum, skin, and overall appearance as well as change in smell. An increasing trend was observed in TBA, TVBN, TMA and the same has been observed in psychrophilic count, Pseudomonas count and H2S producer count. E grade was noticed up to 2nd day for Sardinella longiceps and 3rd day of storage for Scomberomorus commerson and Etroplus suratensis. A grade was observed until 3rd day for Sardinella longiceps and 4th for Scomberomorus commerson and Etroplus suratensis. Finally, B grade was noticed on 5th day for Sardinella longiceps and 6th day for Scomberomorus commerson and Etroplus suratensis. Above changes were well supported by sensory evaluation of sample. A combination pictorial, sensory, biochemical and microbiological changes was used to develop grading of species studied in chilled storage. Exporters can utilize this data to rate the quality of commercially importance species. |
