The sensory analysis was carried out at 30 d of ripen- ing (Figure 4). Results showed that scores found for tactile sensations and some taste features were signifi- cantly different (P < 0.05).
To better visualize any differences among cheeses from different milks, with respect to microbiological characteristics and sensorial attributes, the scores from descriptive sensorial analysis were used to construct a PCA biplot (Figure 5). The PCA resulted in 2 principal components that accounted for about 95% of the total variance. Mixed ewe cheeses (CE) were located in a well-defined area where cheeses displayed higher scores for intensity of flavor, acidic, astringent, friability and salty attributes. Hardness increased, in accordance with what was found by Aminifar et al. (2013). In contrast, mixed goat cheeses (CG) were found in an area where the solubility, together with the intensity
