Quality assessment of rotating and solar tunnel dried marine fish product
Studies were conducted to evaluate the quality aspects of marine dried fish i.e. silver jewfish (Johnius argentatus), Bombay duck (Harpodon nehereus) and ribbon fish (Trichiumshaumela) products produced in rotating and solar tunnel dryers. On the basis oforganoleptic characteristics such as colour, odour, texture, broken pieces, insectinfestation and overall quality, four member panels of experts evaluated the quality of thedried products obtained from both rotating and solar tunnel dryers and all the productswere found in acceptable quality. Reconstitutions properties of samples were in the rangeof 51.05 to 98.75% for the dried fish produced in rotating dryer, while 24.64 to 76.76% fordried fish produced in solar tunnel dryer. The highest reconstitution rate was found indried silver jew fish and lowest in ribbon fish produced in rotating dryer. On the otherhand, the highest reconstitution was observed in dried silver jew fish and lowest in driedBombay duck produced in solar tunnel dryer. Proximate composition such as moisture,crude protein, lipid and ash content of the dried fish muscles produced in rotating dryerranged from 16.36% to 19.1%, 62.35% to 67.37%, 6.37% to 10.75% and 7.00% to 8.05%,respectively and in solar tunnel dried fish products, they were in the range of 14.05% to19.71%,57.64% to 69. 21%,6.92% to 15.40%and 7.69% to 8.80 %, respectively. The TVBNvalues of dried fish products obtained from rotating dryer were in the range of 15.02 to19.05 mg/100g, while in solar tunnel dried fish products, the values were in the range of15.46 to 19.21 mg/100g. The results of the studies indicated that dried fish produced fromboth rotating and solar tunnel drier were acceptable quality in terms of organoleptic andfood quality aspects.
