Supplementary Fig. 1 - Schematic diagram of the production of blueberry polyphenol-protein

matrices. The standard procedure consisted of complexing the concentrated blueberry extract

after ethanol removal with organic whole wheat flour, chickpea flour, coconut flour or soy

protein isolate and submitting the mixtures to vacuum oven drying, freeze drying or spray

drying in order to obtain polyphenol-protein aggregate matrices.

Supplementary Fig. 2 - Representative HPLC chromatogram showing relative abundance of

individual anthocyanins in blueberry polyphenol-protein matrices obtained by the complexation

of concentrated blueberry extract and protein sources (wheat flour, chickpea flour, soy protein

isolate, coconut flour) by freeze drying, vacuum oven drying and spray drying. Compound
