this research was conducted to compare effects of electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kgy on soybean meal (sbm) ruminal degradation kinetics of crude protein (cp) and amino acids (aa). the nylon bag and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) techniques were used for this aim. ionizing radiations decreased washout and degradati...

The half-cystine residues involved in linking the acidic and basic polypeptides were determined for several glycinin subunits. The cystines were localized with specific cyanogen bromide fragments either by comparing the electrophoretic mobility of nonreduced and reduced fragments, or by co-purifying and then determining the NH2-terminal sequence of the covalently linked fragments. Residues invo...

Two experiments were conducted to investigate the in vitro ability of keratinase to hydrolyze soybean glycinin and β-conglycinin and to evaluate the in vivo effects of keratinase when included in corn-soybean diets with different levels of crude protein and fed to nursery pigs. In experiment 1, a saturated keratinase solution (1 ml) was added to two blank controls of either glycinin or β-congly...

The relationship between the rheological behavior and microstructure of glucono-δ-lactone (GDL) induced cold-set soybean glycinin (Gly)–locust bean gum (LBG) mixed gels was studied. In the presence of 0.05%, 0.10% and 0.15% w/v LBG, the onset of Gly network formation (4.0%, w/v) occurred progressively earlier and the viscoelastic modulus was enhanced significantly as the LBG concentration incre...
