The PLSR2 analysis performed on the sensory attributes and the underlying FB design showed that the FBs were separated by the different concentrations of lime flavour across Component 1 which explained 24.6% of the Y variance and 72.5% of the X variance and the different concentrations of fibre across Component 2 which explained 20.9% of the Y variance and 20.5% of the X variance (Fig. 1).
