The H∗ increases in CAE juices are higher to those observed for the same storage period in other anthocyanin rich products as strawberry marmelades ( García-Viguera et al., 1998). The higher stability observed in marmelades can be due to other factors that preserve the anthocyanin colour expression such as lower acidification with citric acid, low water activity, pectins, other phenols, etc.
