“…For each of the seven studies, two consumer segments were identified using Euclidean distances and Ward's agglomeration criterion. Considering the relatively small sample sizes, the number of clusters in each study were restricted to two (Varela, 2014).…”

“…Agglomerative Hierarchical Clustering (AHC) was performed on the IMA and VA scores in order to identify groups of consumers with different patterns (Varela, 2014). Euclidean distance and Ward´s agglomeration methods were employed.…”

“…Additionally, the average acceptability scores of each cluster obtained by AHC were plotted as vectors. As indicated by Varela (2014), the direction of each vector represents the direction of increasing acceptability scores for each consumer cluster (Figure 1A), and is linked to the position of the foal meat samples in the plane (Figure 1B).…”

“…Esta metodologia ganhou popularidade por causa de sua simplicidade e facilidade de uso (ADAMS et al, 2007;ARES et al, 2010;VARELA;. Neste método uma lista de termos é apresentada aos consumidores e estes são solicitados a selecionar todos os que eles consideram apropriados para descrever o produto.…”

“…Mesmo os métodos descritivos, como a Análise Descritiva Quantitativa, sendo amplamente usada como referência para os perfis sensoriais, deparam-se com algumas limitações, como a dificuldade de medir percepções e o elevado custo requerido para treinar e manter uma equipe de provadores treinados (DEHLHOLM et al, 2012;VALENTIN et al, 2012;VARELA;. Neste contexto, o objetivo deste capítulo foi caracterizar sensorialmente as mortadelas saudáveis, utilizando Analise Descritiva Quantitativa (ADQ) e as perguntas CATA, avaliando a relação das mesmas com a aceitação geral, utilizando PLSR e Análise de Penalização.…”
