Previous issue date: 2016-12-12 / O peixe voador ? um importante recurso pesqueiro do litoral nordestino. No entanto, seu consumo ? desvalorizado pela popula??o em fun??o da grande presen?a de espinhas em seu m?sculo. O processamento deste pescado possibilita a obten??o da Carne Mecanicamente Separada (CMS), a qual pode ser utilizada como mat?ria-prima para produ??o de diversos alimentos. O objetivo deste trabalho foi desenvolver formula??es de hamb?rguer de peixe voador (Hirundichthys affinis) e avaliar a influ?ncia do alecrim no perfil sensorial e qualidade do produto durante o per?odo de armazenamento. Foram produzidas tr?s formula??es de hamb?rguer com diferentes quantidades de alecrim: F1(0%), F2 (0,5%) e F3 (1%). Para a caracteriza??o do produto foram realizadas an?lises de composi??o centesimal e microbiol?gica. O perfil sensorial do hamb?rguer foi avaliado por meio da An?lise Descritiva Quantitativa (ADQ), ap?s v?rias etapas de forma??o de um painel sensorial treinado. A avalia??o das altera??es f?sicas e f?sico-qu?micas ao longo do tempo foram verificadas realizando-se an?lises de umidade, pH, acidez e an?lise colorim?trica. O hamb?rguer de peixe voador apresentou teor de carboidratos de 8,3%, prote?nas 12,88%, lip?deos 0,99% e valor cal?rico equivalente a 93,66 Kcal, por 100g de amostra. Todas as formula??es apresentaram-se dentro dos crit?rios microbiol?gicos recomendados no in?cio e no final do per?odo de armazenamento. Os valores de umidade n?o apresentaram diferen?as entre as formula??es ao longo do per?odo de armazenamento. A acidez da amostra F1(sem alecrim) aumentou significativamente ao final do per?odo de armazenamento, enquanto o pH aumentou ao final do armazenamento apenas para F2 e F3 (p<0,05). Com rela??o ? cor, observou-se uma diminui??o significativa nos valores de *a em todas as formula??es. Por meio da ADQ observou-se uma tend?ncia ? manuten??o de descritores referentes ? qualidade sensorial para as amostras com maior teor de alecrim, quando comparado ?s amostras sem alecrim. / Flying Fish is an important fishery resource of the northeastern coast. However, its consumption is devalued by the population due to the large presence of pimples in the muscle. The processing of this fish allows the production of Mechanically Separated Meat (CMS), which can be used as raw material for production of various foods products. The objective of this work was to develop formulations of flying fish burguers (Hirundichthys affinis) and evaluate the influence of rosemary in the sensory profile and quality of the product during the storage. Three formulations of hamburguers were produced with different amounts of rosemary: F1(0%), F2 (0.5%) and F3 (1%). For the characterization of the product were performed analysis of proximate composition and microbiological. The sensory profile of the burgers was evaluated using the Quantitative Descriptive Analysis (QDA), after several stages of formation of a sensory panel trained. The evaluation of the physical properties and physico-chemical properties over time were verified by analysis of moisture, pH, acidity and colorimetric analysis. Flying fish burger presented carbohydrate content of 8.3%, protein 12.88% lipids 0.99% and caloric value equivalent to 93.66 kcal per 100 g of sample. All formulations were in acordance with the microbiological criteria at the beginning and end of storage period. Moisture values showed no differences between the formulations during storage period. Acidity of the sample F1 (without rosemary) increased significantly at the end of the period of storage, while the pH increased at the end of the storage only for F2 and F3 (p<0.05). With regard to color, we observed a significant decrease in the *a values of all formulations. Trought QDA analisis we observed a tendency of maintenance of descriptors related to the sensory quality for samples with higher content of rosemary, when compared to the samples without rosemary.
