Thanks to Squarespace for sponsoring this video. Thanks also to our supporters on ___________________________________________ Astringent plant chemicals called tannins bind proteins on mucous membrane and skin, generating a prickly, puckery mouthfeel from foods and letting us “tan” skins into leather. ___________________________________________ If you want to learn more about this topic, start your googling here: Tannin: a yellow or brownish chemical present in some plant tissues, used in leather production and ink manufacture, and a contributor to the sensation of astringency Astringency: the sensation caused by the contraction of body tissues due to tannins, often called “mouthfeel” Polyphenol: a chemical compound containing more than one phenolic hydroxyl group, of which tannins are a major group Phenolic: a chemical compound with a hydroxyl group (oxygen & hydrogen) linked directly to a benzene ring ___________________________________________ Credits (and Twitter handles): Script Writer: Alex Reich (@alexhreich) Script Editor: Kate Yoshida (@KateYoshida) Video Illustrator: Ever Salazar (@eversalazar) Video Director: Henry Reich (@MinutePhysics) Video Narrator: Emily Elert (@eelert) With Contributions From: Peter Reich, David Goldenberg Music by: Nathaniel Schroeder _________________________________________ Like our videos?
