RESUMEN
In order to improve nutritional and functional quality, chicken burgers were made with different amounts of chia seed (0, 2, 4 and 8%) as pork fat replacers and evaluated for the microbiological, technological and sensorial characteristics. The proximate composition and the microbiological characteristics of raw burgers were in accordance with Brazilian legislation. Higher additions of chia increased the amount of dietary fiber (up to 1.46%) and carbohydrate in the products and reduced the fat content by up to 29%. The addition of chia seed reduced the a* values and increased the h* values of the raw burgers and reduced the tenderness and degree of lipid oxidation in the cooked burgers. Lower sensory taste scores and overall acceptance were conferred on products with higher chia addition; although, the degree of acceptance of the products was high. Results of this study highlighted the potential use of chia seed in the elaboration of low fat and enriched dietary fiber burgers.(AU)
No intuito de melhorar a qualidade nutricional e funcional, hambúrgueres de frango foram elaborados com diferentes quantidades de semente de chia (0, 2, 4 e 8%) em substituição ao toucinho e avaliados quanto às características microbiológicas, tecnológicas e sensoriais. A composição centesimal e as características microbiológicas dos hambúrgueres crus estavam de acordo com o preconizado pela legislação Brasileira. Maiores adições de chia aumentaram a quantidade de fibra dietética (até 1,46%) e de carboidrato nos produtos e reduziu os valores de gordura em até 29%. A adição de semente de chia reduziu os valores de a* e aumentou os valores de h* da cor dos hambúrgueres crus e reduziu a maciez e o grau de oxidação lipídica nos hambúrgueres cozidos. Menores notas sensoriais de sabor e a aceitação global foram conferidas aos produtos com maior adição de chia, embora o grau de aceitação dos produtos tenha sido elevado. Os resultados deste estudo destacam o potencial de uso da semente de chia na elaboração de hambúrgueres com baixo teor de gordura e enriquecidos de fibra dietética.(AU)

RESUMEN
OBJECTIVE: This study aimed to develop a value-added product concerning technological and sensory characteristics changes of the use of mechanically deboned poultry meat (MDPM) as meat replacer in lamb and mutton emulsion-type sausages (mortadella). METHODS: Sausages were produced with lamb and mutton and with different contents of MDPM. Six treatments, using lamb or mutton and 0%, 30%, and 60% of MDPM in relation to the meat batter, were produced and analyzed for pH, proximal composition, calcium and residual nitrite content, water activity, 2-thiobarbituric acid reactive substances (TBARS), instrumental color and texture profile. The sensory profile of the mortadella's was also evaluated by acceptance test and check-all-that-applies (CATA) analysis. RESULTS: The MDPM addition increased (p<0.05) fat, residual nitrite and calcium content in the all sausage formulations, but mutton sausage had (p<0.05) higher fat and lower moisture content than lamb sausage. The pH, water activity, TBARS index and color was not affected by MDPM additions, while the mutton sausages were significantly redder (higher a*, C*, and lower h°) and darker (lower L*) than lamb sausages. Adding up to 60% of MDPM reduced (p<0.05) sausages hardness and chewiness. Overall, the meat replacement by MDPM increased the sausages acceptance, but the mutton sausage with 30% of MDPM replacer were the most preferred. Consumers related that pink color, glossy appearance, poultry meat-like taste, soft texture, juicy and greasy mouth feel to all sausages contain MDPM according to CATA analysis. CONCLUSION: Mutton from culled ewes can be utilized for mortadella production with 30% replacement of lean mutton and fat by MDPM.
