Biochemical and Amino Acid Profiles of Two Smoke-dried Fish Species From the Hill Streams of Manipur, India

Abstract

Two smoke dried fish Schizothorax and Ompok species from the hill streams of Manipur were studied. Proximate composition, and amino acid values were determined. High protein content (70.08%) was in Schizothorax and lipid content was high(19.62) in Ompok species. Moisture range was between 9.34 and 10.45% and ash was between 5.34-3.23%. All the amino acids were present except arginine and cysteine. Lysine was in maximum level 12.25-9.93g/100gm) among the essential amino acids of the fishes examined. Among the non- essetial amino acids, maximum level (20.76-18.21g/100gm) was with glutamic acid followed by aspartic acids 11.37-10.24g/100gm). The present study indicates that the fish species were good sources of protein with different essential amino acids.
