Comprehensive Analysis of the Short-Dough Biscuits' Texture To evaluate the texture of biscuits comprehensively, a sensory evaluation was carried out. Then, to detect relationships occurring between acoustic, mechanical and sensory texture properties, a PCA with classification was performed taking into account the initial results. The criterion for selecting the number of components which was taken into account during interpretation was the Kaiser criterion(only those factors are used which correspond to eigenvalues greater than 1) (Stanisz 2007). Acoustic(sound amplitude, energy of acoustic event, duration of acoustic event, acoustic energy), mechanical(force and breaking work) and sensory properties(crispness, hardness and loudness) were active, i.e., took part in the analysis. However, water activity and moisture content were additional parameters, i.e., they were not taken into account in the calculations but only projected on to the main components in the system. The texture of biscuits was described using two components Pci and PC2 explaining 83.8% of its variability(Fig. 3). The first component(PC1) was created by acoustic
