The effect of condensed tannins on goats’ body weight
Tannins are one of the most common plant secondary compounds. Amongst the tannins are condensed tannins (CT), which occur nearly in every plant species browsed by goats. Condensed tannins have a potential to bind proteins, reduce the feed intake and consequently reduce the body weight gain of …

Roles of tannase and hydrolyzable tannins in chestnut blight
<u>Endothia parasitica</u> (Murr.) P. J. & H. E. Anderson (syn: <u>Cryphonectria parasitica</u>(Murr.) Barr), the causal agent of chestnut blight, was able to grow in total aqueous and tannin extracts from blight-susceptible American chestnut as well as in blight-resistant Chinese chestnut bark …

The Effect of Condensed Tannins on Bacterial Diversity and Metabolism in the Intestinal Tract
… mechanism of tannin-resistance. Wattle condensed tannins were determined to be toxic to Escherichia coli in aerobic medium primarily because they generate hydrogen peroxide. The oxidative stress response helps E. coli strains to overcome this inhibitory effect.

Effects of tannins on protein digestibility and detoxification activity in gray squirrels (Sciurus carolinensis)
… were fed acorns or diets containing commercial tannins to determine the effects of tannins on digestion and detoxification (glucuronidation) activity. In the Acorn experiment, Northern red oak acorns (Quercus rubra), white oak acorns (Q. alba), or rat chow were fed to squirrels. Levels of …

In vitro and in vivo effects of sorghum condensed tannins encapsulated in kafirin microparticles on digestive amylases
… Polyphenols like sorghum condensed tannins (SCT) inhibit α-amylase and α-glucosidase enzymes. However, orally administered SCT may have poor inhibitory action against amylases, due to non-specific protein binding. Research is required to determine how to effectively deliver SCT to …

The Effects Of Acidic Conditions And Tannins On The Survival, Development, And Behavior Of Cope’s Gray Treefrog (Hyla Chrysoscelis)
… conditions, with and without the added stress of tannins, on the survival, development, and anti-predator behavior of Hyla chrysoscelis tadpoles. I conducted a field oviposition study to determine adult female site choice, and reared tadpoles in acidic and tannic conditions to investigate survival …

Tannin – starch interplay: Investigating the impact of grape tannins on the properties of various starches : A dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Food Innovation at Lincoln University
… Interaction of starch with bio-molecules such as tannins can significantly enhance the overall textural-cum-nutritional properties of starch. Tannins, a rich source of phenolic compounds and exhibits antioxidants activity, can interact with various molecules, including starch and proteins in …

Nutritional Ecology of White-Tailed Deer: Assessment of an Index to Diet Quality and a Repellent
… repellents exist for deer, most are ineffective. Tannins are a plant defensive compound that have an astringent taste, reduce digestibility, reduce protein availability, and are toxic to rumen microbes, resulting in the reduction in feeding by large herbivores. I hypothesized that chemical …

Basic studies of the cross-linking reaction of collagen with oxazolidine and plant polyphenols
… the reaction between collagen, condensed tannins and oxazolidine, two prodeiphinidin tannins have been studied: extracts from pecan nutshell pith and myrica esculenta bark. The tannin chemistry study showed pecan tannins are copolymers of catechin and gallocatechin with a ratio 1:6 and …

Tannin content of English walnuts : thesis ...
… The need for finding new domestic sources of tannins is apparent when the amounts of domestic and imported extracts are compared. During the period 1940-1950, only 744,394,560 pounds of natural tannin extracts were produced domestically as compared to 1,579,244,280 pounds of tannin extracts …
