Current assay aims at the preparation of onion biscuits with the inclusion of different levels of aromatized fishmeal from the carcasses of the Nile tilapia (Oreochromis niloticus) to assess their chemical composition and analyze their sensorial and microbiological features. Carcasses (spine with ribs and adhering meat after filleting) were washed and immersed in brine 20% (2:1 -brine volume /weight) with a mixture of 50 g of dehydrated rosemary, marjoram, sage, oregano, chives and parsley. The carcasses were drained, smoked, pressed, ground, dehydrated and ground for the second time. The onion biscuits included 0%, 10%, 20% and 30% fishmeal. There was a positive linear effect for protein, ashes and minerals, but no significant difference for humidity and lipids. A negative linear effect occurred with carbohydrates, with a decrease from 53.75% to 40.56%, similar to calorie rates (from 386.30 to 356.05 kcal/100 g). There was no significant difference for sensorial attributes and purchase intention. Scores ranged between 5.08 and 7.14 for aroma, taste, texture and color (scale 1-9) and between 2.70 and 3.28 for buying intention (scale 1-5). Results show that the product lay within microbiological standards required by Brazilian sanitary law. It is concluded that owing to the sensorial analysis, up to 30% of aromatized fish meal may be included, with an increase in the rates of protein and minerals coupled to the reduction of carbohydrate and calorie rates. RESUMOO objetivo deste trabalho foi elaborar palitos de cebola com a inclusão de diferentes níveis de farinha aromatizada a partir de carcaças de tilápia-do-nilo (Oreochromis niloticus) para avaliar a composição química, análise sensorial e microbiológica. As carcaças (espinhaço com as costelas e carne remanescente da filetagem) foram lavadas e imersas em salmoura a 20% (2:1 -volume da salmoura/peso) com uma mistura de 50 g de alecrim desidratado, manjerona, sálvia, orégano, cebolinha e salsa. Após, foram drenadas, submetidas à defumação, prensagem, moagem, desidratação e nova moagem. Foi incluído 0%, 10%, 20% e 30% de farinha de peixe na elaboração dos palitos. Houve efeito linear positivo para proteína, cinzas e minerais, mas não houve diferença significativa para umidade e lipídeos. Para carboidratos houve efeito linear negativo, reduzindo de 53,75% para 40,56%; o mesmo efeito ocorreu para valor calórico (386,30 a 356,05 kcal/100 g). Também não houve diferença significativa para os atributos sensoriais e intenção de compra. As notas variaram de 5,08 a 7,14 para os atributos aroma, odor, textura e cor (escala de 1 a 9), e de 2,70 a 3,28 para intenção de compra (escala de 1 a 5). Análise microbiológica mostrou que o produto estava dentro dos padrões microbiológicos exigidos pela legislação brasileira. Conclui-se que, em função das notas obtidas na análise sensorial, pode ser incluído até 30% da farinha aromatizada nos palitos de cebola, com acréscimo no teor de proteína, minerais e redução nos carboidratos e valor calórico.Palavras chave: análise senso...
The aim of this study was to develop a lasagna pasta enriched with dried mix of tuna (30%) and tilapia (70%) and formulate ready lasagna with enriched pasta. Lasagna pasta was elaborated with increasing levels (0, 5, 10 and 15%) of dried mix. Moisture, lipids and calories were not different between the inclusion levels; crude protein and ash increased linearly, carbohydrates reduced linearly, according to increasing levels of inclusion. There was an increase in n-3 and n-6 fatty acids with the inclusion of mix in lasagna. Between lasagna prepared with different sauces (tuna, chicken and bolognese), and pasta with 15% mix, it was observed that tuna lasagna had lower moisture content and higher protein, lipids, ash, carbohydrates and calories. All lasagna showed optimal sensory acceptance, indicating that the inclusion of 15% dried mix of tilapia and tuna in the pasta is feasible to improve the nutritional composition of lasagna.Keywords: fish processing waste; pasta enrichment; Oreochromis niloticus; Thunnus sp.Practical Application: Lasagnas with fish dehydrated mix have high nutritional value and great sensory profile.
The present study deals with dehydrated mixture of salmon (20%) and tilapia (80%) at 0, 5, 10 and 15% inclusion levels in spinach cake, and evaluates its proximate composition, sensory and microbiological characteristics. It was included 0, 5, 10 and 15% of the dehydrated mixture in the dough of the cake. Moisture and lipid contents were not modified (p >0.05) when the mixture was included in the cake. There was a positive linear effect for crude protein (y=6.24 + 0.29x, R²=0.77) and mineral (y=0.60 + 0.19x, R²=0.85). Carbohydrate and calorie contents decreased linearly (p <0.01) according to increasing levels of the mixture in the cake. With regard to sensory analysis, there was a negative linear effect for taste (y=7.48-0.07x, R 2 =0.98), texture (y=7.48-0.047x, R 2 =0.93), acceptance (y=7.13-0.046x, R 2 =0.99) and purchase intention (y=3.82-0.039x, R 2 =0.93), demonstrating that increasing levels of inclusion of the dehydrated mixture caused a decrease in the acceptance of the cake. It can be concluded that the inclusion of up to 15% of salmon and tilapia dehydrated mixture in spinach cake increases the contents of crude protein and mineral matter, and reduces the carbohydrate content and calorie. However, based on the sensory results, it is recommended to include 10% of the dehydrated mixture of fish in the spinach cake.
ABSTRACT. Current assay deals with the preparation of alfajores with different levels (0 to 15%) of dehydrated fish mixture of salmon (10%) and tilapia (90%) to assess the sensorial characteristics and their centesimal composition and microbiological. Fish inclusion in alfajores did not affect the aroma, taste, texture, color and physical aspect, with scores ranging between 6.70 and 7.96 of a hedonic scale of 9 score. An average score of 4 in a 5-score purchasing intention scale was obtained, or rather, tasters would probably buy the product. In the case of centesimal composition, inclusion affected (p <0.05) humidity (between 2.74 and 3.40%) and ash (between 0.31 and 1.01%) rates, with a quadratic effect; protein (between 5.35 and 7.12%) with positive linear effect; carbohydrates (between 72.64 and 75.79%) with negative linear effect. There was no difference (p >0.05) in lipids and calorie rates in the alfajores. Results show that the inclusion of up to 15% of a dehydrated mixture of salmon (10%) and tilapia (90%) in alfajores was greatly accepted and improved their nutrition values. Further, the product was also within the microbiological standards required by Brazilian sanitary laws.Keywords: Filleting waste, fish in sweet products, fish protein concentrate, fish carcass.Características nutricionais, microbiológicas e sensoriais de alfajor elaborado com mix desidratado de salmão e tilápia RESUMO. O objetivo deste estudo foi elaborar alfajores com diferentes níveis de inclusão (0 a 15%) do mix desidratado de salmão (10%) com tilápia (90%) e avaliar as características sensoriais, composição centesimal e microbiológica. A inclusão do mix de peixe no alfajor não interferiu em seus parâmetros sensoriais de aroma, sabor, textura, cor e aparência, cujas notas variaram de 6,70 a 7,96, pela escala hedônica de 9 pontos. Para intenção de compra, considerando a escala hedônica de 5 pontos, obteve-se nota média 4, cujo valor significa que os avaliadores possivelmente comprariam o produto. Em relação à composição centesimal, a inclusão do mix influenciou (p <0,05) nos teores de umidade (2,74 a 3,40%) e nas cinzas (0,31 a 1,01%) proporcionando efeito quadrático, na proteína (5,35 a 7,12%) efeito linear positivo, enquanto nos carboidratos (72,64 a 75,79%) linear negativo. Não houve diferença (p >0,05) para extrato etéreo e valor calórico dos alfajores. Conclui-se que a inclusão de até 15% do mix desidratado de salmão (10%) com tilápia (90%) no alfajor, teve boa aceitação e melhorou sua composição nutricional, além do produto estar dentro dos padrões microbiológicos exigidos pela legislação brasileira.Palavras-chave: resíduos de filetagem, peixe em produtos doces, concentrado proteico de peixe, carcaça de peixe.
