which
allows measurement of selected phenolic compounds released
from the ingested product as an indicator of their bioavailability.
The main objectives of this research were to determine the changes
in total phenolic content, total proanthocyanidin content and some
highly abundant anthocyanins as well as changes in their antioxidant
and antiproliferative activity during gastro-intestinal digestion
of chokeberry juice under acid conditions in the presence of
complex food matrix.
