Proximate composition and nutritional value of fish powder composition (FPC) from different dried SIS fishes in Bangladesh

Abstract

The biochemical compositions and nutritional value of Small Indigenous Species (SIS) fishes were analyzed using analytical techniques. Proximate composition of five dried fish species viz. Glossogobius giuris, Colisa fasciata, Puntius ticto, Eutropiichtheys vacha, Corica soborna and a group of mixed SIS fishes viz. Chanda nama, Chanda ranga, Amblypharyngodon mola, Mastacembelus pancalus, Xenentodon cancila were selected for preparation of powder (FPC) which can be preserved for a time period. The fishes were sun dried or oven-dried. Quality of the oven-dried fish was better than that of the sun-dried fish, but sun drying process is easy and can be used in large scale. The fish powder remained in good condition up 7 to 9 months at normal room temperature, but at -18oC the powder was in good condition throughout the year. Highest quantity of powder from 1 kg of fish was obtained in C. soborna (25.80%) and the lowest in G. giuris (11.72%). Biochemical analysis showed that the maximum moisture are found was 14.28% in G.giuris and minimum was 12.05% in C. soborna. Maximum protein content was recorded in G. giuris (73.32%) and minimum was 58.06% in mixed SIS fishes. The maximum fat content of selected dried fish was 23.63% in C. soborna and minimum was 1.29% in E. vacha. The maximum calcium content was found was 2.53% in P. ticto and minimum was 1.66% in G. giuris. Maximum phosphorus content was 2.93% in C. fasciata and minimum was 1.85% in some mixed fishes. Maximum iron content was found as 32.00 mg/100g in mixed SIS fishes and minimum was found as 20.25 mg/100g in P. ticto. The results indicate that SIS fishes has high nutritional value in terms of protein, fat, and minerals.
