Tannins are a unique category of plant phytochemicals especially in terms of their vast potential health-benefiting properties. Researchers have described the capacity of tannins to enhance glucose uptake and inhibit adipogenesis, thus being potential drugs for the treatment of non-insulin dependent diabetes mellitus. Thus, the present research was conducted to find out tannin content of food p...

African leaves (Vernonia amygdalina Del) is a plant that can be used as medicinal because it contains flavonoid compounds are effective natural antioxidants suppress free radicals. The purpose of this study was to determine the antioxidant activity purified extract Vernonia Del. Antioxidant test Del against 1,1-diphenyl-2-picrylhydrazil (DPPH) measured with UV-Vis spectrophotometer at wavelengt...

Bran extracts (70% aqueous acetone) of specialty sorghum varieties (tannin, black, and black with tannin) were used to investigate the effects of sorghum phenolic compounds on starch digestibility, Estimated Glycemic Index (EGI), and Resistant Starch (RS) of porridges made with normal corn starch, enzyme resistant high amylose corn starch, and ground whole sorghum flours. Porridges were cooked ...

The effect of dietary condensed tannins (proanthocyanidins) on rat fecal bacterial populations was ascertained in order to determine whether the proportion on tannin-resistant bacteria increased and if there was a change in the predominant bacterial populations. After 3 weeks of tannin diets the proportion of tannin-resistant bacteria increased significantly (P < 0.05) from 0.3% +/- 5.5% to 25....

LIM, S. H., DARAH, I. & JAIN, K. 2006. Antimicrobial activities of tannins extracted from Rhizophora apiculata barks. Tannin which was extracted from barks of Rhizophora apiculata was further separated into hydrolysable and condensed tannin. The results of the study revealed that only hydrolysable tannin showed significant antibacterial and antiyeast activities but not antifungal activity. The ...

Horse gram was germinated at 90% RH at 25°C for 72 h after 24 h soaking and then grinded to pass through 150 μm mesh size screens. The germination of horse gram result in increased protein, fiber, total polyphenol content, and antioxidant activity of horse gram flour whereas fat, ash, carbohydrate, iron, calcium, tannin, phytate, and oxalate were reduced due to germination. Bread was prepared b...
