    Biochemical and Microbial Changes during Ice Storage of Mystus gulio and Puntius sophore
    (Society of Fisheries Technologists (India)Cochin, 2013) Nath, Kapil Deb; Majumdar, R.K.; Debbarma, Sujata
    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.
