Figure S1. Methoxylation degree of purified unbound pectin (UP) and bound pectin (BP) fractions during dehydration of the three varieties Corvina, Sangiovese and Oseleta. The data obtained clearly show that UP fraction is characterised by a higher methoxylation degree that helps in explaining why this fraction is not retained in the column. On the contrary, BP fraction, due to a lower amount of methoxyl groups, and hence a higher degree of negatively charged residues, is bound to the diethylaminoethyl (DEAE) cellulose.
