RESUMO

In the first instance an attempt was made to confirm that the trimethylamine oxide (THA-O) of red meat fish is completelv reduced to trimethvlamine when these fish were submitted to high temperatures, as in the case of canned tunas and bonitos. An attempt was made to use the following chemical determination to identifv the biological species employed in the preparatíon of cans of tunas and bonitos: non-protein nitrogen (NPN), total nitragenated bases ( TB ) , volatile nitrogenated bases (VB) trimethylam.ine ( TMA) and true protein (Preal ), the letter being obtained through the difference between the total nitrogen content of the sample and its NPN content. Commercial samples of tunas and bonitos of both national and imported origins were analyzed. The influences of form (solid or grated) and season (winter or summer in the southern hemisphere) at the time of manufacture were also evalluated. Note: the complete abstract is avaiable with the full eletronic digital theses or dissertations
