Introduction of the extension region of beta-conglycinin alpha' subunit at the C-terminus of proglycinin A1aB1b results in the improvement of its emulsifying properties. To understand the basic for such improvement, we introduced the alpha' and alpha extension regions to the A2B1a C-terminus, and the alpha extension and A5A4B3 hypervariable regions, and an oligopeptide composed of 20 negatively...

Large amounts of the major storage proteins, beta-conglycinin and glycinin, in soybean (Glycine max) seeds hinder the isolation and characterization of less abundant seed proteins. We investigated whether isopropanol extraction could facilitate resolution of the low abundant proteins, different from the main storage protein fractions, in one-dimensional polyacrylamide gel electrophoresis (1D-PA...

To fabricate a soy protein emulsion with good storage stability against microorganisms, we investigated the stability and antimicrobial activity of a b-conglycinin (7S) and chitosan (CS) mixed emulsion at acidic pHs. Results of droplet size and microstructure showed that 7S/CS mixed emulsions were stable at acidic pHs while the 7S emulsion was not. As for the storage test, results showed that t...

This study investigated the glucono-δ-lactone (GDL)-induced aggregation of isoflavones and soy proteins in soymilk. High-performance liquid chromatography (HPLC) analysis indicated that isoflavones mixed with β-conglycinin (7S) and glycinin (11S) proteins formed 7S-isoflavone and 11S-isoflavone complexes in soymilk supernatant fraction (SSF). Most of the soy protein-isoflavone complexes then pr...

Abstract Soybean meal (SBM) is a common plant-based protein source in the swine industry. Its crude content 44 to 50%. However, presence of antinutritional factors such as high molecular weight, difficult digest proteins, phytate and non-starch polysaccharides (NSP) limit its use pigs. We aimed fermentation approach improve nutrient value SBM. have screened, from different sources, identified b...
