When comparing the degree of hydrothermal degradation of
proteins and carbohydrates (Fig. 2a and b) it can be observed that
carbohydrates are more susceptible to SubCW induced reactions
than proteins in the applied temperature range. As already mentioned
in Subsection 3.3, this difference could be a consequence
of unequal solubilities of the two materials. Furthermore, the reactivity
could also be dependent on the ability of the water molecules
to reach the reaction site i.e. on degree of crystallinity of the two
materials etc. Based on these observations, it can be concluded that
hydrothermal degradation reactions of SubCW can indeed have a
more selective behaviour towards different types of chemical compounds
as was assumed.
