Abstract/ Executive Summary:

Proximate composition, quality aspect and heavy metal concentration of sun-dried Bombay Duck (Harpodon nehereus) and sun-dried Ribbonfish (Trichiurus haumela) were studied in a series of laboratory experiments. Sun-dried fishes were collected from a fish market of Cox?s Bazar town. These sun-dried marine fishes were collected from the stock after first drying procedure. Organoleptically most of these sun-dried fishes were in „B? grade that means in „Good? condition (SDP 2.33 and 2.35 respectively). Crude Protein, Lipid, Moisture, Ash, TVB-N and TMA-N content (%) of sun-dried Bombay Duck (Harpodon nehereus) was 32.21±1.05 %, 3.51±0.38 %, 37.26±0.70 %, 16.22±0.56 %, 115.45±1.73 mg/100g, 9.37±0.13 mg/100g respectively. Whereas in sundried Ribbon fish (Trichiurus haumela) the content (%) of Crude Protein, Lipid, Moisture, Ash, TVB-N and TMA-N was 31.64±1.28 %, 5.06±0.10 %, 35.78±0.97 %, 12.33±0.27 %, 107.69±1.37 mg/100g and 9.91±0.23 mg/100g respectively. Heavy metal concentration i.e. Cd, Cr, Pb, Cu and Zn concentration (ppm) in sun-dried Bombay Duck (Harpodon nehereus) was 0.82, 8.38, 8.28, 2.21, 55.38 ppm. Whereas heavy metal concentration (ppm) in sun-dried Ribbonfish (Trichiurus haumela) was Cd 0.48 ppm, Cr 6.96 ppm, Pb 5.46 ppm, Cu 1.40 ppm, Zn 19.95 ppm.

Objectives:

The objective of the present research was the determination of sensory quality, nutritional composition (Protein, Lipid, Ash, Moisture), freshness and quality (TVB-N and TMA-N) and safety aspects in terms of heavy metal concentration e.g. concentration of Cd, Cr, Pb, Cu, Zn. Such research is important and expected to contribute to producing reliable data and information. Such data and information will be helpful to develop effective quality control and Assurance Programme as well as to produce a safe product for export as well as for domestic consumption.

Methodology:

Source of Sun-dried fish Sun dried Bombay duck and sun dried Ribbon fish were collected from Cox's Bazaar District about a year before the beginning of analysis. After collection, the samples were transported to the laboratory of Fisheries Technology Department, Bangladesh Agricultural University, Mymensingh. Finally carefully packed in several jars and kept in a storeroom at room temperature. Stored samples were used for consequent laboratory analysis. Sensory Quality assessment Sensory quality as for example colour, odour, taste and texture, infestation, broken pieces of sun-dried Bombay duck (Harpadon nehereus) and sun-dried Ribbon fish (Trichiurus haumela) was conducted by the organoleptic method of Howgate et al. (1992). In doing so the SDP (Score of Defect Points) was calculated first. Then Grading was done according to the recommended Table shown below.
