The objective of the study was to reduce
post-harvest losses by developing a fish chub using Clarias
gariepinus and to determine the
effect of Monodora myristica (local
nutmeg) and sorbitol on the physical quality, proximate composition and
trimethylamine content of the product. Cooled smoked samples were
packaged and stored at refrigerated and frozen storage conditions and examined
for 1-12 weeks under frozen and 1-7 days under refrigerated condition at intervals. The
yield for the fish chub production was about 35 %, while 65% of the starting material was lost during
processing. The protein content of the samples varied between 13% and 25%.
Frozen fish chubs stored at ﹣18℃ had a shelf life of about six weeks while the
refrigerated fish chub (7℃-10℃) sample had a shelf life of about 4 days. The
combined use of local nutmeg and sorbitol increased the shelf life under both
storage conditions. The production of fish chub could be a viable
economic venture in places where catfish is readily available and
it is likely to improve protein intake of the consumers and reduce post-harvest
losses.
