Abstract
Biochemical, microbial and organoleptic changes in
two commercially important fishes (Mystus gulio
and Puntius sophore) during ice storage have been
studied. Ash content, lipid content, total nitrogen
and non-protein nitrogen showed a decreasing
trend whereas pH and salt soluble nitrogen showed
reverse trend during the ice storage period. TVBN
increased to 29.87 mg% on 10th day in P. sophore
whereas, it crossed the border line of spoilage on
13th day in M. gulio. Aerobic plate count reached
to 106g-1 on day 13 and day 10 for M . gulio and P.
sophore respectively. Results obtained in the sensory
analysis correlated well with the observed biochemical
changes. The study indicated that the edible
quality of M. gulio and P. sophore was maintained
upto 13 and 10 days respectively when stored with
ice.
