Comparison of acceptability of tropical fruit mixed nectars by mean test and multivariate statistical analysisComparação da aceitabilidade de néctares mistos de frutas tropicais por teste de médias e análise estatística multivariada

Abstract

Fruits are a rich source of nutrients and fruit juices are a popular way of consuming them. Development of mixed juices, where two or more fruit juices are blended to obtain a product that combines the nutritional value of fruits, has been encouraged by the food industry and well accepted by consumers. This work aimed to develop mixed nectars of tropical fruits (cashew apple, mango and acerola) and to compare the acceptability data by mean test and multivariate statistical analysis of hierarchic grouping and principal compounds. The tropical fruit nectars showed good acceptability, the formulations with higher mango and cashew and lower acerola contents the most accepted. The formulation with 12.25% cashew apple pulp, 21% mango pulp and 1.75% acerola pulp had the highest global evaluation score. However, it could be observed by the cluster analysis of consumers’ data and posterior principal components analysis of these results a clearly segmentation of consumers. As frutas são fontes ricas de nutrientes e os sucos de frutas são formas mais populares de consumi-las. O desenvolvimento de sucos mistos, em que duas ou mais frutas são misturadas para se obter um produto que combina o valor nutricional das frutas, tem sido estimulado pela indústria de alimentos e bem aceita pelos consumidores. Este trabalho teve como objetivo desenvolver néctares mistos de frutas tropicais (caju, manga e acerola) e comparar os dados de aceitabilidade por teste de média e análises estatísticas multivariadas de agrupamento hierárquico e componentes principais. O resultado do teste de médias indicou uma maior aceitação para os néctares com maiores teores de manga e caju e menores teores de acerola. A formulação contendo 12,25% de polpa de caju, 21% de polpa de manga e 1,75% de polpa de acerola teve o maior escore na avaliação global. No entanto, pode ser observado pela análise de cluster de dados dos consumidores e posterior análise de componentes principais destes resultados claramente uma segmentação dos consumidores.
