The aim of the present study was to understand to what extent the inclusion of anthocyanins into dairyand egg matrices could affect their stability after processing and their release and solubility during digestion.For this purpose, individual and total anthocyanin content of four different enriched matrices,namely custard dessert, milkshake, pancake and omelettete, was determined after their manufacturingand during in vitro digestion. Results showed that anthocyanin recovery after processing largely variedamong matrices, mainly due to the treatments applied and the interactions developed with other foodcomponents. In terms of digestion, the present study showed that the inclusion of anthocyanins into foodmatrices could be an effective way to protect them against intestinal degradation, and also the incorporationof anthocyanins into matrices with different compositions and structures could represent an interestingand effective method to control the delivery of anthocyanins within the different compartments ofthe digestive tract.
