TL;DR: In this article, the effect of the human microbiota on the metabolism of different tannin groups and the expected health benefits that may be induced by such mutual interactions was summarized. And explainable artificial intelligence was used to define the molecular signatures of gut-biotransformed tANNin metabolites that are correlated with chemical and biological activity.

TL;DR: In this paper , a review summarizes the applications of various mass spectrometry and nuclear magnetic resonance (NMR)-based metabolomics technologies in determining the impact of coffee breeding, origin, roasting, and brewing on coffee chemical composition, and considers this in relation to quality control (QC) determination, for example, by classifying defected and non-defected seeds or detecting the adulteration of raw materials.

TL;DR: In this article , the authors assessed the effect of the gut microbiota on the biotransformation of O. ficus-indica metabolites both in vitro and ex vivo using UHPLC-QTOF-MS, with flavonoid glycosides completely hydrolyzed in vitro at 24 h being converted to two major metabolites, 3-(4-hydroxyphenyl)propanoic acid and phloroglucinol, concurrent with an increase in the gallic acid level.
