Comparing with compounds derived from cane pigments, these compounds present a higher molecular weight and a lower colour variation, with pH. As a matter of fact, the IV of these compounds varies between 1.0 and 3.3 (Table) (Clarke et al., 1987) while colourants derived from cane have IV values untill 33 (Paton, 1992).
