Aceitabilidade de barra de cereais potencialmente probiótica

Abstract

A utilização de micro-organismos probióticos é uma das mais atrativas opções para consumo humano, devido às suas excelentes propriedades funcionais. Considerando-se que o desenvolvimento de novos produtos tem adquirido crescente importância, objetivou-se, neste trabalho, avaliar a aceitabilidade de barras de cereais com micro-organismos potencialmente probióticos. Utilizou-se a escala hedônica estruturada de nove pontos, que contém os termos descritivos situados entre "gostei extremamente" e "desgostei extremamente". Os atributos avaliados foram: aparência, textura, sabor e impressão global. Foi também realizada uma pesquisa de intenção de consumo, utilizando-se uma escala de cinco pontos situados entre "nunca comeria" e "comeria sempre". A avaliação sensorial foi realizada por uma equipe de 36 indivíduos não treinados: professores, estudantes e funcionários da Universidade Federal do Espírito Santo, de ambos os sexos, com idades entre 20 e 40 anos. As amostras foram apresentadas aos provadores em ordem aleatória, de forma monádica, devidamente identificadas com números de três dígitos. A utilização da levedura Saccharomyces boulardii e da bactéria Lactobacillus acidophilus, por meio das diferentes formas de incorporação nas barras de cereais, não interferiu na qualidade sensorial e estrutural do produto. As quatro formulações de barra de cereais apresentaram boa aceitação sensorial quanto a aparência, textura, sabor e impressão global. A pesquisa de intenção de consumo revelou que mais de 60% dos provadores consumiriam o produto sempre ou frequentemente. A viabilidade dos micro-organismos por curto período de tempo torna necessária a realização de novos estudos, com o objetivo de aumentar a estabilidade destes micro-organismos durante a vida de prateleira do produto.
