Interaction of Condensed Tannins with Biopolymers
Condensed tannins form complexes with a multitude of species, ranging in size from divalent and trivalent metal ions to macromolecules, both naturally occurring and synthetic. Many of these complexes are of low solubility, permitting detection by techniques as simple as precipitation. Determination of the interactions responsible for the initial events in complex formation is facilitated by the use of techniques that can detect the interaction in extremely dilute solution, thereby suppressing the influence of aggregation.
