Abstract

Viscera from freshwater fish, constituting 5-11% of body weight, consists of (%) water 67, proteins 10, ether extracts 14, and minerals 3. Process of ensiling fish viscera after mixing individually with different levels of molasses (7.5, 10.0 and 12.5%, w/w) with (2 and 4%, w/w) or without salt was studied under microaerophilic condition at ambient (26±2°C) temperature. Data revealed that the optimum level of molasses was 10% of fish viscera, acid production being inadequate with 7.5% molasses, while it did not improve, but resulted in lower rise in fermenting mass with the use of 12.5% molasses. Salt lowered the swelling of fermenting mass, the efficiency being higher with the use of 4% salt, in addition to significantly (p< 0.001) reducing the rate of acid production during the first two days of fermentation. Subsequently, pHs of salted samples were markedly (p<0.001) lower than those of non-salted samples.
