Biochemical analysis of Five Dried Fish species of Bangladesh

Abstract

Abstract:To assess the proximate composition, five dried fish samples of Mystus vittatus, Channa punctatus, Chanda nama, Corica soborna and Trichuirus haumela were selected. The moisture content ranged from 14.06% to 24.58%, protein varied between 44.08% to 65.65% (moisture basis) and 53.45% to 76.39% (dry matter basis), lipid content of the selected dried fishes ranged from 1.91% to 17.76% (moisture basis) and 2.31% to 21.54% (dry matter basis). Ash content varied from 9.63% to 22.73% (moisture basis) and 11.21% to 28.15% (dry matter basis). The experiment was replicated three times and conducted from February, 2009 to August, 2009. Samples were collected from Sayedpur Upazaila, Nilphamari District, the north-west region of Bangladesh.Key Words: dried fish, moisture, crude protein, lipid and ash IntroductionFreshwater fishes play a vital role for animal proteins in the world. Approximately 16 percent of animal proteins consumed by the world's population are derived from fishes, and over one billion people depend on fish as their main source of animal proteins (FAO, 2000). Fishes are easily digestible nature of proteins and are important source of essential minerals. Besides, the dried fishes are also rich in other nutritional components (Nettleton, 1992;Graikoski, 1998;Basu and Gupta, 2004). Laureti (1998) established that dried fishes often are an alternative to fresh fishes in many places. According to DoF (2011) significant amount of dried fishes (approximately 622 mt) were exported and earned 25.06 core taka of foreign currency. But many cases it does not possible to get similar flavor, taste or texture from dried fishes. Saha (2003) reported that in Bangladesh most of the market samples become slightly odourless and some lose the shelf life where rancid and bitter tastes are developed. Nutritional composition also varied in large scale in different dried fish product. Now-a-days consumer wants to know and ensured the nutritional value of the products what they are eating. Although a good number of works on the biochemical composition of fishes in Bangladesh have been done by many researchers viz. Rubbi et al. (1987), Mollah et al. (1998Mollah et al. ( , 2000, Nurullah et al. (2002Nurullah et al. ( , 2003, Islam et al. (2003), Mazumder et al. (2008). But the dried fishes both freshwater and marine species were not focused. So the present investigation was carried out in order to assess the percentage of proximate composition of five fish species through laboratory analysis.

Development and Biochemical Composition Assessment of Fish Powders from Bangladeshi Indigenous Fish Species and Shelf-Life Characteristics Evaluation During 90 Days of Room Temperature (27°C - 30°C) Storage

“…Our findings reveal that the protein contents in all the samples are higher which make them highly suitable for food application especially for the development of protein-enriched food commodities. Our results were found slightly higher than the study [42] where protein content ranged from 52.65% to 72.45% in seven dried fishes. Although, the protein contents differ with species to species due to some obvious factors such as the effect of spawning and migration and food availability, etc.…”

“…Another investigation by [41] reveals that in case of dried food materials, the moisture content for dried food materials less than 10% is regarded as more efficacious for keeping the quality attributes. Our investigation also found that the moisture content of L. rohita was below the study by [42] in which they found the moisture contents of L. rohita 9.07%. Another study [39] determined that the mois- .50%, which is significantly greater than our investigation [11].…”

Comparative Studies of Nutritional, Microbial and Organoleptic Properties of Different Indigenous Dried Fish from Local Market in Bangladesh

“…The more or less close result found by Azam et al [19] observed that fat content was in fourteen selected dried fish range of 7.1% to 26.13%. The lipid content in batashi fish was 3% reported Flowra et al [20] this value was lower than that we did. According to the report of Nurullah et al, [21] the lipid content of solar dried SIS (A. mola, O. cotio cotio, P. atherinoides, M. vitatus and G. chapra) varied from 14.10 to 16.26%.…”

Biochemical Quality Assessment of Fish Powder

“…There are some related studies [3][4][5][6][7][8][9][10][11][12][13] focusing on the biochemical and nutritional studies of some freshwater raw as well as dried fish species. Although several studies are concerned with the proximate composition of biochemical components of many commercially important fishes, but no such work has been carried out on the selected fish powder of Bangladesh.…”
