This investigation shows the influence of the fermentation process started with the probiotic Lactobacillus paracasei LMG P-22043 (PF) on the fate of health promoting polyphenols in artichoke in comparison with not started fermented artichokes (NSF). The fermentation process did not influence significantly the polyphenol compositions. However, low variations mainly related to the isomerization process of dicaffeoylquinic acids, probably due to the different pH values of the two samples, were observed. Further, the total polyphenol bioaccessibility of PF artichoke was lower (34%) than of NSF artichoke (64%) in small intestine. Moreover, both polyphenol isomerization and bioaccessibility influenced the antioxidant activity that was significantly lower for PF artichoke than for NSF ones. These effects were probably related to the bioprotective process exerted by the probiotic strain on the food matrix, with the consequent limited release of polyphenols in the digestion liquids, making them available for further metabolism and absorption in the colon.
