A total of 450 1-d-old male broiler chicks were fed a corn-soy-flax meal-based diet (control), two cultivars of sorghum--Ruby Red (low tannin content) and Valpo Red (high tannin content)--were used at 10% level. Birds were slaughtered at the end of 42-d feeding trial. Boneless, skinless breast and thigh muscles were separated and ground to make patties. Half of the breast and thigh meat patties...

Tannin acyl hydrolase also referred as tannase is an enzyme with important applications in several science and technology fields. Due to its hydrolytic and synthetic properties, tannase could be used to reduce the negative effects of tannins in beverages, food, feed, and tannery effluents, for the production of gallic acid from tannin-rich materials, the elucidation of tannin structure, and the...

Two experiments were carried out to determine the nutritive value and to evaluate the performance of growing rabbits fed on isoenergetic diets containing high moisture sorghum silage grain with low or high tannin levels. In the digestibility assay (experiment 1), the nutritive values of silages were determined with 30 New Zealand White rabbits, 15 males and 15 females, 55 days old, allotted in ...

Pomegranate (Punica granatum) peel is a nutritive, antioxidant rich byproduct, easily available after production of pomegranate juice and ready to eat arils. The present study is undertaken to know the nutritional importance of fresh and detanninated pomegranate peel powder. Fresh pomegranate peel collected after juice extraction from Bhagwa variety of pomegranate. Fresh peels were crushed fine...

this experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. for tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. then, pistachio by-products were removed from the water and ...

Antiviral activity has been demonstrated for different tannin-rich plant extracts. Since tannins of different classes and molecular weights are often found together in plant extracts and may differ in their antiviral activity, we have compared the effect against influenza A virus (IAV) of Hamamelis virginiana L. bark extract, fractions enriched in tannins of different molecular weights and indi...

Regarding some reported antimicrobial properties of tannins; Zymomonas mobilis was used to obtain ethanol from tannin-reduced carob pod extract (TR-CPE). Culture of 50 mL volume containing 7.5 g sugar at pH 5.5 and 0.03 g bacterial inoculums with shaking at 80 rpm was used. Using response surface methodology (RSM), the maximum ethanol concentration of 5.34 % w/v (higher than that reported earli...

In a previous study by the authors, particleboard was manufactured using a new natural adhesive composed of tannin and sucrose. The optimal ratio between tannin and sucrose was 25/75, and the suitable resin content was 30 to 40 wt%. In this study, the effects of hot pressing temperature and hot pressing time on board properties were investigated. The optimal values for the hot pressing temperat...
