Fig. 5From: Stability of total phenolic concentration and antioxidant capacity of extracts from pomegranate co-products subjected to in vitro digestionChanges in ferric reducing antioxidant power (FRAP) during in vitro digestion model of water, 50 % ethanol and 100 % ethanol extracts of pomegranate peel, marc and juice. Average values (±S.E) of triplicate measurements are presented. Bars with different letter(s), per co-product for each solvent extract, are statistically significant different (p < 0.05).
