Soybean (Glycine max (L.) Merr.) is an important protein source in human diets and animal feeds. The sulphur content of soybean seed proteins, however, is not optimal for ration formulations. Thus, increasing the methionine and cysteine content of soybean seed proteins would enhance the nutritional quality of this widely utilized legume. We have earlier reported the isolation of an 11 kDa delta...

UNLABELLED Soybeans are an important legume crop that contain 2 major storage proteins, β-conglycinin and glycinin, which account about 70- 80% of total seed proteins. These abundant proteins hinder the isolation and characterization of several low abundant proteins in soybean seeds. Several protein extraction methodologies were developed in our laboratory to decrease these abundant storage pro...

Soymilk prepared from germinated soybean [Glycine max (L.) Merrill] with different hypocotyl lengths was fermented at 42 °C for approx. 4 h to produce soy yogurt (sogurt) with the combined probiotics of Lactobacillus helveticus B02, Streptococcus thermophilus IFFI 6038 and Lactobacillus bulgaricus AS1.1482. The physicochemical, textural and sensory characteristics of the fermented products were...

The carotenoid biosynthetic pathway was genetically manipulated using the recombinant PAC (Phytoene synthase-2A-Carotene desaturase) gene in Korean soybean (Glycine max L. cv. Kwangan). The PAC gene was linked to either the β-conglycinin (β) or CaMV-35S (35S) promoter to generate β-PAC and 35S-PAC constructs, respectively. A total of 37 transgenic lines (19 for β-PAC and 18 for 35S-PAC) were ob...

Bioactive peptides content in foodstuffs can seriously vary with many factors such as crop variety, food processing, animal breeding, etc. Because of this variability, quantitative methodologies are required to evaluate the content of bioactive peptides in foodstuffs. Progress in liquid chromatography and mass spectrometry technologies offer a great opportunity for the quantitation of bioactive...

Seed protein quality is an important topic in the production of soybean. The quality of soybean proteins is limited by anti-nutrient proteins and low levels of essential sulfur amino acids. In this study, protein content and solubility of six cultivars were evaluated and seed storage proteins were analyzed using SDS-PAGE and scanning densitometry. The results showed that seed storage protein ba...
