For this study, it has been demonstrated that when subjects let
the dark chocolate pieces melt in mouth, the shape influenced
texture and flavour perception. Sensory profiling results revealed
significant differences in perceived melting and smoothness. There
were smaller but significant differences in perceived cocoa, caramel
and aftertaste. Moreover, timeeintensity results showed the
chocolate shape impacted the timing of cocoa perception (start
time and end time of the plateau). In further work, to completely
rule out a potential impact of the shape appearance on these
sensory results, it will be worth doing an expectation study
