Values are expressed as the mean ± standard deviation (mg/100 g); n—number of measurements; Cy-spoh—cyanidin-3-spohoroside; Cy-glu-rut—cyanidin-3-glucosyl-rutinoside; Cy-glu—cyanidin-3-glucoside; Cy-rut—cyanidin-3-rutinoside; Plg-glu—pelargonidin-3-glucoside; mDP—mean degree of polymerization; TPH—total polyphenols; terminal and extension units represent percent of the (+)-catechin and (−)-epicatechin placed in the terminal or extension position of flavanols chemical structure.
