| dc.description.abstract | The aim of the present study was to study the combined effect of gamma irradiation and low temperature storage on the microbial and biochemical quality of fish (Pangasius hypophthalmus). Samples were divided into two main packs, each of the main packs were subdivided to four separate lots, one being the control and rest of the three were exposed to 1.0 kGy 3.0 kGy and 5.0 kGy levels of gamma irradiation and the packs were stored in iced and refrigerated condition. The influence of irradiation on iced and refrigerated samples were evaluated for microbial, biochemical and sensory attributes. Microbial parameters like total plate count showed a reduction and absence of pathogens in iced (0 ± 2°C) and refrigerated (6 ± 2°C) storage in comparison to control for 12 and 21 days respectively. Biochemical parameters like PV, TBARS, and TVBN increased gradually during storage period signifying the quality deterioration as duration of storage increased. The sensory scores for overall acceptability were found to be decreased in control samples compared to iced and refrigerated stored samples. The study showed that low dose, gamma irradiation can be applied to improve biochemical safety indices and to extend the shelf life of pangasius fish fillets up to 12 days at ice and 21 days at refrigerated storage without adverse effects on the quality and acceptability. Gamma irradiation at 3KGy was observed to be best treatment, because it recorded the highest values of all quality parameters. In addition, the current studies showed the synergistic effect of the two preservation methods, food irradiation and ice/refrigerated storage, on extending the shelf life of pungasius fish fillets. | |
