Model juices at pH 3.7 were prepared with different combinations of ascorbic acid, rutin (quercetin 3-
rutinoside) and concentrated anthocyanin extract of plums (cv. Black Gold). The anthocyanins in the concentrated
extract were cyanidin 3-glucoside and cyanidin 3-rutinoside, in a proportion of 76% and 24%
respectively. The model juices were stored during 17 weeks in darkness at 20 C. The colour stability
was improved by the presence of rutin and strongly damaged by the ascorbic acid. The fortification of
anthocyanin model juices with ascorbic acid originated the degradation of most of anthocyanins. However,
anthocyanins improved ascorbic acid stability during storage. The copigmentation of anthocyanin
and rutin showed a beneficial effect on colour stability from the 5 weeks of storage. In model juices prepared
exclusively with purified plum extract a high correlation (R2 = 0.881) between anthocyanins and
antioxidant capacity was found.
