Soybean protein concentrate (SPC) modified with condensed mimosa tannin (CT) were employed as eco-friendly and formaldehyde-free adhesives for glued-wood joints. Eucalyptus grandis wood boards free of knots cracks used substrate. Thermogravimetric analysis (TGA) showed that provided higher thermal stability to the adhesive, which allowed expanding temperature range hot pressing. Apparent viscos...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

this study was conducted to evaluate the effects of different heating treatments (autoclaving, roasting, steam flaking and microwave irradiation) on chemical composition, anti- nutritional compounds (tannin and phenolic), in situ dry mater (dm) and crude prate in (cp) degradability. three fistulated bull in a complete randomized block design and in vitro gas production kinetics (complete random...

The goal of this study was to evaluate the effects of dosing unadapted lambs with tannin-tolerant bacteria to improve the digestibility of a high condensed tannin (CT) diet. During the initial phase (metabolism study), a diet containing 30% peanut skins was fed to two groups of Suffolk FinnDorset ram lambs that were about three months old and weighed an average of 24.2 1.4 kg. All animals recei...

Low dietary energy and decreased intake of herbage have been attributed to the reduced performance grazing dairy cattle. We hypothesized that grasses with inherently greater would interact in a complementary way condensed tannins (CT) birdsfoot trefoil increase by heifers. Eight pasture treatments comprising high-sugar perennial ryegrass (Lolium perenne L.), orchardgrass (Dactylis glomerata mea...

BACKGROUND The study on phytochemical difference between red and black goji berry is limited. METHODS Antioxidant activities and phenolic profiles in terms of total phenol content, total flavonoid contents, condensed tannin content, monomeric anthocyanin content, and total carotenoid content of red goji berry (Lycium barbarum) and black goji berry (L. ruthenicum) were compared using colorimet...

Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West Asia. The detrimental effect of broomrape parasitism in crop yield can reach up to 100% depending on infection severity and the broomrape-crop as...

Condensed tannin sulfonate derivatives were studied by fast atom bombardment mass spectrometry (FAB-MS) to assess the feasibilitY of using this technique for determining molecular weilht and structural information about these compounds. Both positiveand negative-ion spectra provided useful data with repro to molecular Weight, cation species present, and presence of the sulfonate moiety. Additio...

Introduction The Lathyrus/lathyrism challenge is broad-based by its nature and requires multi-disciplinary efforts of specialists in the field of epidemiology, neurology, biochemistry, chemistry, nutrition, and agronomy. The role of chemists is in systematic determination of minor natural products in L. sativus seeds so that the sole responsibility of ß-ODAP for neurolathyrism is ascertained . ...
