ORGANOLEPTIC, BIOCHEMICAL, AND MICROBIAL ANALYSES OF BRYCINUS NURSE PROCESSED USING DIFFERENT SOURCES OF ENERGY

Abstract

Organoleptic, biochemical, and microbial analyses of smoked dried Brycinus nurse stored at room temperature
for 28days were investigated. A modified drum-type smoking kiln (SABAMY) was used for smoking the fish. One
hundred and fifty (150) B. nurse samples were obtained from Gubi dam, Ganjuwa, Bauchi State. The fish were
divided and processed using three different methods: Smoke-dried with firewood (A), smoke-dried with charcoal
(B), and Smoke-dried with sawdust (C). Non-parametric ANOVA analysis revealed that there were significant
differences (x ≥ 3) in the sensory parameters (taste, colour, odour, and texture) assessed. The fish samples from
treatment C were better in terms of taste, colour, odour, and texture. The ANOVA of the proximate compositions
of the processed fish within the storage period showed that samples from treatment A were significantly different
(P > 0.05) in all the parameters (moisture, ash, crude protein, and lipid) except in fibre, where there was no
significant difference. Bacterial count within the first 7 days and the last7 days for all the methods were within
the acceptable limit of 1.0 x 106cfu/g. Further studies should be conducted on using SABAMY smoking kiln in
processing other fish species, and the comparative efficiency of SABAMY with other smoking kilns.
