Fish silage from by-products of non-tradable fishing. Chemical composition and pH
Abstract
The influence of a number of factors upon the chemical composition and pH of storaged fish silage was studied. This fish silage is a byproduct of non-commercial tilapia (Oreo- chromis aureus) fishing. A completely randomized design with a factorial arrangement including byproduct shape effect (chopped and minced fish), commercial sulphuric acid ratio (55; 60, and 65 mL/kg fish), and time (0; 24; 48, and 72 hours) was applied. pH during storage process was measured every 24 hours. The chemical composition of the final product was evaluated. Neither byproduct shape nor sulphuric acid ratio affected fish silage chemical composition. Fish silage can be stored with a pH value from 1,50 to 1,90.
