Tannins, Astringency, and Bitterness: Molecular Mechanisms and Sensory Perception

This review article examines the astringency and bitterness of tannins, polyphenol compounds found in many foods and beverages. The authors discuss the molecular mechanisms behind these taste sensations, focusing on tannins' interactions with salivary proteins and oral cells, as well as the role of bitter taste receptors (TAS2Rs).
