Molecular cloning and characterization of two genes encoding dihydroflavonol-4-reductase from Populus trichocarpa. [PDF]

PLoS ONE, 2012
Dihydroflavonol 4-reductase (DFR, EC 1.1.1.219) is a rate-limited enzyme in the biosynthesis of anthocyanins and condensed tannins (proanthocyanidins) that catalyzes the reduction of dihydroflavonols to leucoanthocyanins.

Guideline for measurement of condensed tannin

Food Frontiers, 2022
AbstractAstringency is a major sensory property and plays an important role in the overall quality of juice and wines. A major contributor to astringency is condensed tannins, which can precipitate with salivary glycoproteins. And thus, it is vital to develop methods to measure the tannin accurately.
