Resumo
Este trabalho teve como objetivo desenvolver formulações de biscoitos tipo cookie contendo café. Desenvolveram-se três formulações com inserção de café como: bebida tipo expresso, café solúvel e café torrado e moído, utilizando como base uma formulação americana adaptada aos ingredientes brasileiros e à inserção de café. A composição centésimal média (base seca) foi: 7% umidade, 70% carboidratos, 8% proteínas, 21% gorduras e 1% minerais, com valor calórico médio de 499 kcal.100 g -1 . A composição centesimal e o valor calórico observados foram similares a valores reportados para biscoitos cookie comercialmente disponíveis. A forma de inserção de café afetou as características sensoriais dos produtos, avaliados por metodologia descritiva de perfil de sabor e de textura. A Formulação 1 (bebida tipo expresso) apresentou valores inferiores para a intensidade dos atributos referentes à presença de rachaduras, fragmentação, presença de pontos escuros, aroma de café e queimado. A Formulação 2 (café solúvel) apresentou notas superiores de intensidade dos atributos de cor marrom, brilho, sabor amargo e de queimado, sabor residual de açúcar mascavo e crocância da borda e inferiores para concavidade. A Formulação 3 (café torrado e moído) apresentou valores superiores para a presença de pontos escuros. As três formulações apresentaram notas satisfatórias e equivalentes de aceitação por crianças.
The aim of the present study is to develop cookie formulations containing coffee. Three formulations were developed, each with a distinct way of adding coffee: espresso beverage, instant coffee and roasted coffee powder. The average proximate composition (dry basis) of the formulations was 7% moisture, 70% carbohydrates, 8% protein, 21% fat and 1% minerals, resulting in an average caloric value of 499 kcal per 100 g product. Both the proximate composition and average caloric value were similar to values reported for existing commercial brands of cookies. It was observed that by adding coffee affected the product sensory characteristics, evaluated by flavor and texture profile descriptive analysis. Formulation 1 (espresso beverage) presented lower values for the following attributes: cracks, crumbling, presence of dark spots, and coffee and burnt flavors. Formulation 2 (instant coffee powder) presented higher values for the brown color intensity, shine, coffee and burnt flavors, residual brown sugar flavor and crunchiness and lower values for concavity. Formulation 3 (roasted coffee powder) presented higher values for the presence of dark spots. All three formulations presented satisfactory grades in terms of children accepting them.
