Article Abstract

Soybean is a staple in the food industry, but can induce allergic reactions that compromise human health. This paper concludes allergenic components in soybean and its allergy mechanism. The mechanism of interaction between polyphenols and proteins and their effects on allergenicity and function are discussed. It is found that soybean allergy is induced by its protein which contains allergens and epitopes. Polyphenols can react with protein via noncovalent reaction (mainly hydrogen bonding, hydrophobic-hydrophobic interactions and ionic bonds) and covalent method (alkaline, enzymatic method and free-radical grafting) to form polyphenols-protein complexes and conjugates, respectively, which dramatically alters protein structure, thus masking and destroying the epitopes to decrease the allergenicity of soybean protein. In addition, oral administration of polyphenols also inhibits allergic reactions induced by soybean protein. The improved functional attributes such as foaming and emulsifying properties are also observed. Therefore, polyphenol modification is a promising way to produce soybean-based hypoallergenic products.

Shade stress alters soybean growth through transcriptomic changes and adaptive responses that optimize light capture and utilization, regulated by a phytohormonal network. This study examined the physiological, morphological, and molecular responses of Guru (shade-tolerant) and Heinong 53 (shade-sensitive) soybean cultivars under 0% (control), 30%, and 70% shade. Results revealed morphological responses where Heinong 53 exhibited greater plant height (52.

Background And Aims: Cell wall invertases have multiple roles in plant growth and development, yet their biological functions in seed oil production are still not understood.

Methods: In the present study, the Oryza sativa (rice) cell wall invertase gene OsGIF1 (GRAIN INCOMPLETE FILLING 1) was ectopically expressed in Glycine max (Soybean) and its functions in grain yield and seed nutrition was investigated.

Key Results: We found that constitutive expression of OsGIF1 significantly improved biomass production, grain yield and seed nutrition in transgenic plants.

Herein, we present a simple and novel method to prepare soybean protein isolate (SPI)-based hydrogels with good mechanical characteristics. First, SPI/DSA hydrogels were prepared using SPI and different M/G ratios (1:2, 1:1, and 2:1) of dialdehyde sodium alginate (DSA). Then, the hydrogels were immersed in CaCl2 solution to form SPI/DSA@Ca double network hydrogels.
