Principal Component Analysis (PCA) was used for exploring
VOC data by Simca P+ v.12 (Umetrics, Sweden). A three-way
ANOVA, using the product and replicate as fixed factors and the
judge as a random factor, was used to evaluate the performance
of the descriptive panel and to identify the sensory attributes to
discriminate the products (Statistica v.9, Statsoft Italia srl).
