Vegetable tannins-based additive as antioxidant for biodiesel
Fuel, 2021Abstract The development of more sustainable antioxidants alternatives for the improvement of biodiesel oxidation stability is gaining importance. Vegetable tannins are known for their antioxidant properties. In this work, acacia (Acacia mearnsii), chestnut (Castanea sativa) and quebracho (Schinopsis lorentzii) tannins extracts were used in mixture ...

Vegetable tannins – Lessons of a phytochemical lifetime
Phytochemistry, 2007After the early encouragement from the outstanding contribution in the early 1900s of Emil Fischer to an understanding of vegetable tannins the work of the following half-century had simply exemplified the complexity of the problems they presented. It was generally recognised [Freudenberg, 1920. Die Chemie der Natürliche Gerbstoffe.

Selective Adsorption of Vegetable Tannins onto Collagen Fibers
Industrial & Engineering Chemistry Research, 2003Vegetable tannins are widely distributed in the plant kingdom. In many cases, it is necessary to remove tannins from natural beverages and medicinal plant extracts due to their physiological toxicity. In the present work, an adsorbent for this purpose was prepared on the basis of hide collagen fibers. Its adsorption selectivity for tannins was studied,

Vegetable oil thermosets reinforced by tannin–lipid formulations
Acta Biomaterialia, 2013Totally bio-based thermosetting polymers which are comparable to synthetic polyester thermosets have been prepared from copolymerization of condensed tannin-fatty acid esters with vegetable oils. Oxidative copolymerization of tannin linoleate/acetate mixed esters with linseed oil and tung oil produced polymer films ranging from soft rubbers to rigid ...

Differential Sensitivity of Mosquito Taxa to Vegetable Tannins
Journal of Chemical Ecology, 1999The sensitivity of larval Culicidae to vegetable tannins was investigated in different taxa representative of the fauna from alpine hydrosystems (Aedes rusticus, Culex pipiens) and foreign noxious fauna (Aedes aegypti, A. albopictus). Bioassays reveal that tannic acid at concentrations of 0.1–6 mM is significantly more toxic for C.

Improving vegetable tannins chemistry: A remarkable advancement in salt-free high tannin fixation
World Journal of Advanced Engineering Technology and Sciences, 2023Traditional tanning practices often result in harmful waste products that pose significant environmental risks, including water pollution, non-biodegradable solids, hazardous emissions, and unpleasant odors. However, this study introduces a simple and effective alternative method for industrial-scale vegetable tanning, with the goal of minimizing ...
