This research work has been conducted to evaluate the effect of gamma radiation and ascorbic acid on organoleptic, biochemical and microbial quality to extend shelf life of freshwater hilsa. Organoleptic evaluation showed that ascorbic acid (1% and 2%) treated and irradiated (1.5 and 3 kGy) samples remained acceptable up to 19 and 21 days, respectively of storage periods at 4 ºC. Tyrosine and phenolic content of fish flesh increased with the increase of storage periods in all the samples but increment of tyrosine value was somewhat lower in irradiated sample compare to control. However, the increasing trend of thiobarbituric acid reactive substance (TBARS) value of fish flesh was higher in both treated samples compared than control. Microbial assessment showed the better result in irradiated (3 kGy) sample compared to other and remained within the safe limit. The present study demonstrates that irradiation is effective for preservation of hilsa at 4ºC temperature. Though, radiation process is expensive and inconvenient, ascorbic acid could be a substitute process for preservation.Pages: 287-291 | 646 Views 58 DownloadsDownload Full Article:
