What is Autolysis and Rancidity Development in Tropical Freshwater Fish Viscera During Fermentation about?
To develop an ensiling process to preserve the nutrients in fish viscera, the offal was homogenised with 10% (w/w) molasses. Propionic acid (0.5% v/w) was added as an antimycotic agent. NaCI (2% w/w) and ethoxyquin (0.02% w/w) were added to see the effect on autolytic changes and rancidity development, respectively. Fermentation was carried out under microaerophilic condition at 26+2°C. Total volatile nitrogen, non-protein nitrogen, alpha-amino nitrogen (autolytic changes) and free fatty-acid content increased (P <O.O01) rapidly during the first 4 days and then remained constant up to 8 days. Salt had no influence on autolysis. Peroxide value (PV) increased (P<O.O01) initially up to 3-4 days and then decreased. A rapid increase (P O.05) subsequent increase in iodine value (IV) were observed. Thiobarbituric acid (TBA) number increased linearly up to 8 days of fermentation period. Ethoxyquin was effective in controlling oxidative rancidity, as indicated by significantly (P <O.O01) lower PVs and TBA numbers and higher IVs.
