Thermodynamical parameters and kinetics of interactions between polyphenols (procyanidins and anthocyanins) and pectic fractions were defined by physico-chemical methods in solution and with a solid support. Experiments confronted major anthocyanins presents in blackcurrant or B-type procyanidins from apple with various degrees of polymerization to pectic fractions from apple pectins presenting different degree of methylation and different neutral sugar side chains.Interactions between anthocyanins and pectins are influenced by the glycosyl substituent and the number of hydroxyl groups in the B-ring of anthocyanins, and by the composition of pectins. The affinity constant of procyanidins – pectins interaction in solution are the highest whe...
