“…Natarajan et al () investigated proteomic and genetic analysis of glycinin subunits in 16 different soybean genotypes and reported that major variations in glycinin subunits between wild and cultivated soybean genotypes. Zilić et al () investigated storage proteins, glycinin (11S), and β‐conglycinin (7S) fractions and their respective subunits in seven soybean varieties. The authors showed that the content and ratios of 11S/7S proteins were varied among the seven varieties.…”

MiniMax was developed as a model soybean for research because of its small stature, limited planting space, and rapid generation time. In the present study, the proteins, isoflavones, and fatty acid methyl esters (FAMEs) were compared between dwarf (MiniMax) and commercially cultivated (Williams 82) soybean genotypes under two growing conditions (greenhouse and field). The protein profile of the soybean extracts by 2D‐PAGE showed at least 16 of 716 spots that were differently expressed in MiniMax and Williams 82. These spots were primarily six proteins namely, seed biotin, β‐conglycinin, glycinin, seed‐maturation protein, glutathione‐S‐transferase, and sucrose binding protein. In both genotypes, higher content of isoflavone aglycones was observed in greenhouse grown samples as compared to the field grown samples. However, only field grown Willams 82 had higher levels of FAMEs as compared to other three groups. This study shows that both growing conditions and cultivars significantly influence the compositional content of metabolites. Practical applications The global demand of soybean and its products has increased due to its high protein and isoflavones content. Researchers are actively developing new genotypes with improved yields, greater drought and disease tolerance, and reduced growth time. MiniMax, a dwarf genotype of soybean showed early flowering, seed setting, and maturation traits due to its multiple dwarfing genes. This characteristic feature enables researchers to study effects of various treatments on soybean in a shorter period with multiple replications in a single growing season.

“…being the most abundant [30]. The ratio between 7S and 11S subunits has an important role in determining the functional properties of food made from soybean [31] and protein quality in soybean as glycinin has more sulphur-containing amino acids (cysteine and methionine) than ß-conglycinin [32]. Furthermore, glycinin is considered to lower the cholesterol levels in human serum [33], and it is important for tofu gel formation [34], whereas α subunit of ß-conglycinin is identified as one of the major allergenic proteins in soybean [32].…”

The potential of soybean for food, feed, and pharmaceutical industry arises from the composition of its seed. Since European countries import 95% of the annual demand for soybean grains, meal, and oil, causing an enormous trade deficit, the governments in Europe had started to introduce additional incentives to stimulate soybean cropping. To rebalance the sources of soybean supply in the future, production must be followed by continuous research to create varieties that would make European soybean more appealing to the processing industry and profitable enough to satisfy European farmers. This chapter is giving an overview of the European soybean seed quality research and an insight into soybean seed quality progress made at the Agricultural Institute Osijek, Croatia. The studies presented are mainly considering maturity groups suitable for growing in almost all European regions. The most important traits of soybean seed quality discussed are protein content and amino acid composition, oil content and fatty acid composition, soluble sugars, and isoflavones. Defining quality traits facilitates the parental selection in breeding programs aiming to improve the added value properties of final soybean products and enables the exchange of materials between different breeding and research institutions to introduce diversity, which is a prerequisite for genetic advance.

“…Rufián-Henares et al [20] explained that the amount of neo-formed contaminants in non-heated cereals and soybean samples indicates initial thermal damage that depends on the amount and type of proteins. In the case of soybean, the high protein content (about 40%) could explain the higher acrylamide generation coming from the MR. Like many globulins from other species, soybean proteins characteristically have a good balance of the essential amino acids [21]. Soybeans are deficient in sulfur-containing amino acids and rich in acidic amino acids, such as aspartic acid and asparagine that correlate with the acrylamide formation.…”
