Ultra‐Tough Hybrid Supramolecular Gelatin Hydrogels

Small, EarlyView.
Tannic acid‐mediated coacervation compacts gelatin into a dense supramolecular network while generating an acidic microenvironment that activates pre‐embedded bis‐oxazoline crosslinkers. The resulting hybrid hydrogel combines covalent stabilization with reversible energy dissipation, producing high strength, extreme extensibility, substantial toughness,

Spectrophotometric Determination of Gallotannins in Beer

Journal of AOAC INTERNATIONAL, 1973
Abstract A method for the determination of traces of gallotannins in beer, in the presence of other natural tannins, has been developed. The procedure is based on the formation of a deep blue iron-tannin complex which is evaluated spectrophotometrically at 530 nm.
