Both of these reactions can contribute to the total
amount of WSE produced, but it is possible that one contributes
more than the other, since hydrolysis of different types of bonds
is preferred at different conditions. For instance, in the article
reported by Rogalinski, Liu, Albrecht, and Brunner (2008), which
studied the hydrolysis kinetics of cellulose, starch and BSA in Sub-
CW from 210 C to 310 C, it was proven that the two carbohydrate
biopolymers were much more susceptible towards hydrolytic degradation
at the studied reaction conditions than the protein one.
Peptide bonds present within the protein structure are therefore
much more stable than glycosidic bonds present within the carbohydrates.
Also, as already mentioned, other products may have
been formed during extraction.
