This study produced fish mortadella from Mechanically Separated Meat (MSM) of Nile tilapia added with animal fat. Three formulations were developed: M1 (MSM - 89 % and 5 % pork fat), M2 (MSM - 84 % and 10 % pork fat) and M3 (MSM - 79 % and 15 % pork fat). The elaborated products were tested for technological, physical, physico-chemical, microbiological and sensory parameters. The results showed that the fish mortadella were microbiologically stable with a particular texture for an emulsified meat product, attractive colour and characteristic flavour. All formulations met the expected identity and quality requirements. They also achieved good acceptance by the judges, in which formulation M1 may be highlighted for presenting an emulsion stability of 97 %, higher protein content (18.09 %) and lower lipids (16.31 %). In addition, it also reached higher mean scores for texture attributes and purchase intent. Therefore, it is possible to prepare fish mortadellas from tilapia MSM using less animal fat.
