The low content in anthocyanins in the juice CAE + AA can be observed from the beginning of the storage, with an initial loss of the 90% of anthocyanins (Fig. 3). Ascorbic acid fortification (50 mg/100 mL) of clarified açai juices has showed the induction of the anthocyanin polymerisation and degradation, with a reaction rate constant and half-life, around 2.4 times higher respect to non-fortified juices. The results of this study also showed that the cyanidin 3-glucoside degradation rates nearly doubled those of cyanidin 3-rutinoside (Pacheco-palencia et al., 2007).
