Taking into account bioaccessibility it can be stated that simulated
digestion released gallic and protocatechuic acids, while
bioaccessibility of ferulic acid and rutin was limited. Unfortunately,
p-hydroxybenzoic, vanilic, syryngic, p-coumaric and synapinic
acids were not detected in fluids obtained after simulated digestion
and absorption, which may indicate their limited bioaccessibility
and bioavailability in model system.
