Elaboração e aceitabilidade de biscoitos enriquecidos com aveia e farinha de bagaço de uva Elaboration and acceptability of cookies enhanced with oat and flour grape pomace

Abstract

A crescente demanda por alimentos benéficos à saúde é acompanhada pela busca por processos que gerem baixo volume de resíduos sólidos ou que proporcionem seu reaproveitamento. Este trabalho propõe a elaboração e a avaliação da aceitabilidade de biscoitos enriquecidos com aveia e farinha de bagaço de uva. A farinha de bagaço de uva, produzida como alternativa de utilização do grande volume deste resíduo gerado pela indústria vitivinícola, representa uma ótima fonte de fibras e antioxidantes naturais de baixo custo. Esta foi obtida por meio da moagem do bagaço seco e posterior padronização granulométrica. A farinha integral de aveia, fonte de fibras alimentares, foi obtida pela moagem da aveia em flocos. Para a elaboração dos biscoitos, foram utilizadas três formulações com diferentes percentuais de substituição da farinha de trigo por farinha integral de aveia e farinha de bagaço de uva, as quais foram denominadas formulações A, B e C, com níveis de substituição de 30%, 40% e 50%, respectivamente. O experimento foi realizado em delineamento inteiramente casualizado, os resultados submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% de significância. Os resultados obtidos demonstraram que os biscoitos elaborados apresentaram propriedades sensoriais aceitáveis, sendo os percentuais de substituição utilizados neste estudo aceitos pelos julgadores, dentre todos os atributos avaliados. O uso da aveia fornece um incremento de fibra alimentar e a farinha de bagaço de uva é um ingrediente alternativo para o reaproveitamento de um produto normalmente descartado.The growing demand for healthy food is accompanied by a search for processes that generate low volumes of solid waste, or which provide for its reuse. This paper proposes the development and evaluation of the acceptability of cookies enriched with oat and grape pomace flour. The grape pomace flour, produced as an alternative to the use of large volumes of waste generated by the wine industry, represents a great source of fibre and natural antioxidants at low cost. It was obtained by grinding the dry pomace and subsequent granulometric standardization. The oat flour, a source of food fibres, was obtained by grinding oat flakes. To prepare the cookies, three formulations with different percentages of replacement of the wheat flour by wholemeal oat flour and grape pomace flour were used, defined as Formulations A, B and C with 30%, 40% and 50% replacement respectively. The experiment was carried out using a completely randomized design, the results submitted to an analysis of variance and the means compared by the Tukey test at 5% significance. The results demonstrated that the cookies presented acceptable sensory properties and the percentage of substitution used in this study was accepted by the judges for all the attributes evaluated. The use of oat provided an increase in food fibre and the grape pomace flour was an alternative ingredient for the reuse of a product normally discarded.
