Phenolic Composition, Radical Scavenging Activity and an Approach for Authentication of Aronia melanocarpa Berries, Juice, and Pomace

Autor: Tuba Esatbeyoglu, Miriam Rodríguez-Werner, Peter Winterhalter

Publikováno v: Journal of Food Science. 84:1791-1798

Aronia melanocarpa is a rich source of phenolic compounds like anthocyanins, chlorogenic acids, quercetin derivatives, and proanthocyanidins possessing strong antioxidative potential. The consumption of A. melanocarpa is actually increasing because o
