Composição química e rendimento do filé de tilápia tailandesa (Oreochromis niloticus).

Abstract

The filet yield and their chemical composition, which as moisture content, proteins, ashes and lipids, were determined. For the analysis 19 tilapia with average weight and length of 989.56g and 38.86cm respectively were used. The fish was weighed and measured (length, width and thickness) and after filleting calculated filets yield. The determination of the chemical composition was accomplished following the AOAC (1995) methodology presenting following contents: 77.13% of moisture content, 2.60% of lipids, 19.30% of proteins and 1.09% of ashes. The weight relations filet/fish and fish/residue presented good linear correlations.
