PREPARATION OF BIO-FERMENTED AND ACID SILAGE FROM FISH WASTE AND ITS BIOCHEMICAL CHARACTERISTICA.U. PAGARKAR, S. BASU, A. MITRA AND N.P. SAHUAbstract Under utilized fishes are generally used for preparation of various value added products such as surimi, extruded fish products and various types of other fish paste products. After extracting meat portion from the fish, remaining body parts which includes heads, fins, guts and scales etc. are disposed as waste. The disposal of waste (by-products) generated during fish processing is becoming a major problem for environmental pollution. The present study was carried out to utilize fish waste eco-friendly by ensiling with lactic acid bacteria (Lactobacilli plantarum), sulphuric acid-and mixture of organic acids (formic acid and propionic acid in 1:1 ratio) at different concentrations. 4% (w/w) sulphuric acid and 4% (w/w) mixture of organic acids formic acid and propionic acid in 1:1 ratio was found suitable for fish silage preparation. Biochemical changes, its composition, nutritive values and advantages of bio-fermented fish waste silage comparison with sulphuric acid and mixture of organic acids are discussed in this paper.
