Abstract
The study aimed to elaborate burgers with fillet and pulp (fish carcass meat) of grumatã (Prochilodus lineatus), and to evaluate its centesimal composition, microbiological and sensorial properties. Three formulations were prepared. One was prepared with the fillet (0% pulp), and the remaining two contained 15% or 30% pulp (instead of fillet), textured soy protein, wheat flour and condiments. The centesimal and microbiological composition was evaluated in pre-ready burgers. For sensory analysis, the burgers were grilled, and untrained judges evaluated the appearance, color, taste, texture, overall acceptance and purchase intent. Dry matter and fat were higher in formulations containing pulp; while crude protein and ash contents were higher in burgers with 30% pulp compared with those produced with fillet only. The coagulase-positive Staphylococcus and total and fecal coliform counts were within normal values established by the Brazilian legislation. Salmonella spp. was detected in the pre-ready (raw) formulations, but no colony was observed in the cooked preparations. Although no difference was found among formulations for sensory attributes, burgers with 30% pulp presented a higher purchase intention index (50%) than the other formulations. The complete use (fillet and pulp) of grumatã meat shows that this species can be utilized to elaborate distinct alimentary formulations.
