Abstract

In this study, the naturally debittered table olives cv Bella di Cerignola were studied in order to (i) characterizetheir phenolic composition; (ii) evaluate the polyphenols bioaccessibility; (iii) assess their absorption and transport, acrossCaco2/TC7. LC-MS/MS analysis has confirmed the presence of hydroxytyrosol acetate, caffeoyl-6?-secologanoside, andcomselogoside. In vitro bioaccessibility ranged from 7% of luteolin to 100% of tyrosol, highlighting the flavonoids sensitivity tothe digestive conditions. The Caco2/TC7 polyphenols accumulation was rapid (60 min) with an efficiency of 0.89%; the overallbioavailability was 1.86% (120 min), with hydroxytyrosol and tyrosol the highest bioavailables, followed by verbascoside andluteolin. In the cells and basolateral side, caffeic and coumaric acids metabolites, probably derived from esterase activities, weredetected. In conclusion, the naturally debittered table olives cv Bella di Cerignola can be considered as a source of bioaccessible,absorbable, and bioavailable polyphenols that, for their potential health promoting effect, permit inclusion of table olives as afunctional food suitable for a balanced diet.
