The area under the curve of the cocoa flavour was larger for the
Sail and the Wing shapes than for Round and Rectangle shapes
(Fig. 8b). This is fully in accordance with intensity scoring from
monadic profiling (r ¼ 0.99). The rank orders of the shapes were the
same in both tests. The plateau started sooner for Rectangle shape
than for Sail shape (Fig. 8c). The timing at which the maximum
intensity of cocoa is perceived may appear to contribute to the
“flavour boost” and thus may contribute to the overall cocoa flavour
intensity measured in sensory profiling. However, there was no
correlation between this parameter and the cocoa flavour intensity
measured in monadic profiling (r ¼ 0.47). The difference highlighted
on the end time of the plateau was due to the Sail shape as it
occurred later than for the other three shapes (Fig. 8d).
