ABSTRACT

Presence of filth and sensory quality, overall quality of five sundried freshwater fish of Dinajpur Sadar Upazilla of Dinajpur district was studied by observation during visit, conducting survey and laboratory experiments on the collected samples. Five freshwater sun-dried fish species were selected for this study. These are Darkina (Esomus danricus), Mola (Amblypharyngodon mola), Jat puti (Puntius sophore), Tengra (Mystus vittatus), Kachki (Corica soborna). Detection of filth was done during visit to the place and interviewing the processors, traders, shopkeepers. Sensory quality and overall quality of the sun-dried fishes were assessed by collecting samples and experiments in the Laboratory of the Department of Fisheries Technology, Bangladesh Agricultural University, Mymensingh. Different types of filth was detected in the sun-dried fishes during this research study. Main categories of detected filth were sand, dust, wing of insect, legs of cockroach, dead- mosquito, butterfly, scales of fish, blow flies, fur of rat, cat, dog. Result of the laboratory analysis reveals that the mean percentage of protein, lipid, ash and moisture content of these dried fish ranged between 33.07 to 55.90%, 13.84 to 23.87%, 18.28 to 32.04% and 10.23 to 21.78% respectively. Sensory quality was found to be excellent and acceptable by organoleptic examination. Overall quality parameters of chemical and biochemical analysis TVB-N and TMA-N were in the range of 16.25 to 38.21 mg/100g dried fish, and 8.28 to 14.41 mg/100g dried fish respectively. The TVB-N and TMA-N values were in the acceptable limit. The findings of this research shows that the sun-dried fishes are highly nutritive and comparable with the other protein source such as mutton, beef etc. But if we consider the survey result the presence of many filth in the sun-dried fish during processing, handling, storage and display makes it aesthetically completely unacceptable.
