The time course of digestion of white bread, fusilli and red kidney
bean, as examples of bakery products, pasta and pulses respectively,
comminuted by the three methods – sieving, chewing and
homogenising – clearly show the cause of differences between
the three groups in terms of the kinetics of digestion (Fig. 5). The
curves for sieved, chewed and homogenised white bread were
identical and parabolic. The curves for pasta were also parabolic
but were dependent on the method of comminution. The curves
for the pulses were all so flat that they were approximately linear
and similar for all three methods of disintegrating within the particle
size range used.
