Effect of freezing period on the microbial and nutrient quality of pool barb, Puntius sophore from Dhaka city retail market, Bangladesh

Abstract

Abstract:The microbiological and nutrient quality of pool barb (Jatpunti), Puntius sophore collected from three local markets -Ananda bazaar, New Market and Polashi bazaar of Dhaka, Bangladesh were assessed. The investigation confirmed more or less higher microbial load in Ananda bazaar samples than the others. The microbial quality varied with market sources as total bacterial counts (TBC), total coliform counts (TCC) and faecal coliform counts (FCC) occurred in all storage period and that crossed the acceptable limit. All studied parameters except E. coli were significantly different at 7 days and 30 days of storage period and a significant difference (p < 0.05) was found in case of E. coli for all storage period where every 30 days storage showed one log reduction of bacterial count from every initial stage. The Salmonella shigella (SS) and Vibrio spp. were identified in all samples of studied local markets. An inverse relation was found between moisture and protein, moisture and fat, whereas the moisture content was increased after 30 days of freezing storage. This study concludes that the quality of P. sophore (Jatpunti) available in the studied three local markets of Dhaka city were neither satisfactory level nor to the standard for normal consumption.

Irradiation as a Promising Technology to Improve Bacteriological and Physicochemical Quality of Fish

“…APC acceptability, according to the permissible limit recommended by [41], is not more than 5 × 10 7 CFU/g for chilled and frozen fish. The results illustrated in this study for the untreated fish were within and above the permissible limit, at nearly the same range as previous reports [48,49], and higher than other studies [50,51]. The high count of S. aureus and high percentages of isolation among different examined fish samples in this and other studies [52,53] were due to fish contamination during harvesting and subsequent unhygienic practices during handling and processing, as S. aureus does not normally appear as a part of the natural microflora of newly caught marine and cultivated fish.…”

“…Ahmed et al, [23] recorded the nutrient composition of indigenous and exotic fishes fat values of P. sophore, P. ticto and X. cancila are 2.28%, 3.56% and 2.76%. Mustafa et al, [24] observed 5.59±0.88%, 5.88±0.92%, 5.65±0.95% fat values in P. sophore from different stations in Bangladesh. Nahid et al, [33] stated that the fat value in muscle of X. cancila is 4.66%.…”

“…Ahmed et al, [23] reported that the nutrient composition of selected fishes and the protein values from 15.6 to 18.5%. Mustafa et al, [24] recorded 17.86 to 18.5±0.92% protein values in muscle of P. sophore. The protein content shows a strong correlation with spawning and breeding.…”

Evaluation of Proximate Composition and Seasonal Variations of the Muscle Tissue of Mouth-Brooding Tilapia Oreochromis mossambica from Meghadrigedda Reservoir, Visakhapatnam, Andhra Pradesh, India

“…The nutrient composition of selected food fishes and their protein and fat values studied by Ahmed et al, [20]. Mustafa et al, [21] observed protein content in muscle of P.sophore and he stated that protein showed a correlate with spawning period. Banik and Saha, [22] explained a sharp decline in the weight of the gonad after spawning.…”
