In addition, the second dimension in Fig. 1B expressed both differences between the two fat levels used in the experiment, and the protein content of the samples. The higher the protein content of the yoghurts, the farther samples were from the reference products (N01 and N02). These differences were related to the flavour char- acteristics expressed in dimension two, i.e., F-sour. Furthermore, higher protein contents resulted in texture characteristics closer to hose from the full fat reference yoghurt (N00), as it is seen in dimension one in Fig. 1B.
