Photodegradation of ciprofloxacin by tannin-barium titanate catalysts and evaluation via artificial neural network modeling approaches [PDF]

open access: yesScientific Reports
The visible-light-driven removal of ciprofloxacin (CIP) remains a challenge due to its persistence and contribution to antibiotic resistance. In this study, tannin-modified barium titanate (BaTiO₃) composites were synthesized using three different tannin

The effect of wine age and tannin composition on tannin activity across consecutive Pinotage red wine vintages

open access: yesOENO One, 2022
The effect of wine age on tannin chemistry and tannin activity values was investigated in red wine extracts according to a chemosensory approach. Sixteen Pinotage red wines of multiple vintages (2003-2018) were each isolated into four distinct polymeric ...

Tannins as Hemostasis Modulators [PDF]

open access: yesFrontiers in Pharmacology, 2022
The hemostasis system is often affected by complications associated with cardiovascular diseases, which results in thromboembolic events. Compounds of plant origin and plant extracts are considered as a promising source of substances that could modulate the functioning of the hemostasis system and thus reduce the risk of thromboembolism.

Persimmon-derived tannin ameliorates the pathogenesis of ulcerative colitis in a murine model through inhibition of the inflammatory response and alteration of microbiota

open access: yesScientific Reports, 2021
Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) induced by dysregulation of the immune response in the intestinal mucosa. Although the underlying mechanisms of UC development are not fully understood, disruption of gut microbiota ...

Effect of protein-tannin ratio and tannin concentration on the bovine serum albumin (BSA)-based precipitation method for red wine tannin concentration

open access: yesOENO One, 2011
Aims: The main objective of the study was to ascertain whether an existing protein precipitation assay could be simply modified to determine tannin at low concentration in wines. This was achieved by mixing a greater volume of wine to a smaller, but more

Reactivity of Larch and Valonia Tannins in Synthesis of Tannin-Formaldehyde Resins

open access: yesBioResources, 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
