Tannins of Constant Structure in Medicinal and Food Plants—Hydrolyzable Tannins and Polyphenols Related to Tannins [PDF]
Molecules, 2011 In addition to the commonly used classification as hydrolyzable tannins and condensed tannins, tannins can also be categorized into two other types: polyphenols of constant chemical structure (Type A) and polyphenols of variable composition (Type B).

Colloidal stability of tannins: astringency, wine tasting and beyond [PDF]
, 2008 Tannin-tannin and tannin-protein interactions in water-ethanol solvent mixtures are studied in the context of red wine tasting. While tannin self-aggregation is relevant for visual aspect of wine tasting (limpidity and related colloidal phenomena ...

Response to dietary tannin challenges in view of the browser/grazer dichotomy in an Ethiopian setting : Bonga sheep versus Kaffa goats [PDF]
, 2015 It has been suggested that goats (typical browser) are better adapted to digest tannin-rich diets than sheep (typical grazer). To evaluate this, Bonga sheep and Kaffa goats were used in a 2x3 randomized crossover design with two species, three diets, and

Longer ensilage time improve rumen fermentation of high moisture – High-tannin sorghum grain
Journal of Agriculture and Food Research, 2023 The high moisture sorghum grain silage is an important source of feed for livestock in Uruguay and some regions of the world. That is why this study aimed to evaluate the effect of ensilage time, moisture content, and variety on the in vitro fermentation

Reactivity of Larch and Valonia Tannins in Synthesis of Tannin-Formaldehyde Resins
BioResources, 2016 Tannin-formaldehyde resins (TFR) were prepared by copolycondensation of tannins (larch tannin or valonia tannin) and formaldehyde. The performances of TFR and the free formaldehyde residue in the system during the course of reaction were tested. Chemical

Salivary proline-rich protein may reduce tannin-iron chelation: a systematic narrative review
Nutrition & Metabolism, 2017 Background Tannins are often cited for antinutritional effects, including chelation of non-heme iron. Despite this, studies exploring non-heme iron bioavailability inhibition with long-term consumption have reported mixed results.
