BACKGROUND This study explores enzymatic hydrolysis as a method of modifying soybean meal (SM). It can reduce the particle size, improve flavor, and convert macromolecules into absorbable nutrients. The purpose is to provide technical information regarding the use of SM. Papain alone, and a combination of papain and acid protease, and a mixture of papain, acid protease, and Lactiplantibacillus plantarum were employed for the enzymatic hydrolysis of SM. RESULTS Sensory evaluation and nutritional and flavor analyses were performed with yogurt produced after SM enzymatic hydrolysis. The enzymatic hydrolysis improved yogurt quality significantly in comparison with non-enzymatically hydrolyzed soybean meal yogurt (SMY) by accelerating the decrease in pH and shortening the duration of fermentation. Enzymatic hydrolysis also reduced beany flavors and bitterness and enhanced the aromatic compound, flavor-related amino acid, and organic acid content, rendering the yogurt more appealing to consumers. Microstructural analysis revealed favorable characteristics that textural and rheological properties of the yogurt produced after enzymatically hydrolyzed SM were improved. CONCLUSION In this study, the biotechnological approach was used to demonstrate the efficacy of enzymatic hydrolysis in improving the quality and value of SM, promoting the efficient application of SM in the food industry. © 2024 Society of Chemical Industry.

Truffle, belonging to Tuber genera, is a nutritious and sterol-rich edible fungus, and sterol is a potential health beneficial compound. A comparison of Tuber sterol composition indicates that the total sterol contents in the fermentation mycelia (i.e., 10.5 mg g −1 ) ( n = 3) were approximately 3.2–5.6 times higher than that of the fruiting bodies ( p < 0.05) with the addition of soybean flour into the basal fermentation media. Moreover, the phytosterol profile of fermentation mycelia could be significantly improved by adding soybean flour into the fermentation media. After the addition of soybean flour, stigmasterol and β-sitosterol appeared in the fermentation mycelia and the contents of total phytosterols (2279 μg g −1 ) ( n = 3), brassicasterol (943 μg g −1 ) ( n = 3), and campesterol (418 μg g −1 ) ( n = 3) were all increased significantly ( p < 0.05). Moreover, the total contents of sterols and phytosterols in the fermentation mycelia cultured in the soybean media were much higher than those in the fruiting bodies (i.e., 1883–3240 and 479–1832 μg g −1 , respectively) ( n = 3, p < 0.05). This work confirms the potentiality of Tuber fermentation mycelia as the alternative resource for its fruiting bodies from the viewpoint of sterols production.

Formaldehyde-free liquid adhesives derived from biomass are attractive candidates to petroleum-based counterparts. However, developing solid bio-adhesive with excellent wet strength and bonding performances remains a lasting challenge. Here, we report a bio-composite sheet consisting of soybean flour , paper, and cross-linking agent (Polyamidoamine-epichlorohydrin, PAE), and its wet strength and bonding performances was evaluated by paper straw and plywood application. The covalent crosslinking by the reaction of soybean protein and PAE plays a major role in the enhancement of various properties of the cured bio-composite sheet. The tensile stress of cured bio-composite sheet was only lower than the prototype sample 14.5% after 100 ℃ water soaking treatment for 2 h. Paper straw rolled from the bio-composite sheet displayed boiling water stable at the same condition, while had better flexural strength and natural degradability than the plastic straw. Bonding strength of plywood boned with bio-composite sheet reached 1.38 MPa, which was exceeded 97.1% than the requirement of the Chinese National Standard GB/T 9846–2015 for interior plywood. Given the simple and general strategy, the products based on bio-composite sheet can potentially be a new approach on the use of biomass adhesives, which also be a suitable solution to solve the environmental challenges (e.g., formaldehyde) in the field of biomass-based composites.

There still exist challenges to regulate the crosslinking network of soybean flour (SF) precisely with both strong and tough mechanical properties to match adhesion requirements of wood adhesives applications. Herein, a novel nanohybrid crosslinker with dynamic bonding effect was synthesized and then employed to improve SF adhesives. Dimethylglyoxime as chain extender was incorporated into polyurethane cooperating with CuO to form dynamic coordination bonds, after which epoxy and siloxane dual-functionalized polyurethane was co-deposited onto cellulose nanocrystal (CNC) surface to construct reactive “rod-bead” nanohybrid named CuOGU@CNC. It is found that epoxy groups induce CuOGU@CNC to form covalent crosslinking interactions with SF matrix constructing a stable adhesive system. Meanwhile, the dynamic coordination bonds of dimethylglyoxime and CuO serve as sacrificial units to contribute for energy dissipation, during which the unique “rod-bead” structure increases contact efficiency between DMG and CuO to optimize bonding exchange rate to high-effectively redistribute stress during loading. Given on the effect, the adhesives modified by CuOGU@CNC present improved dry and wet adhesion strength , and adhesion toughness compared to pristine SF sample. This work can provide a facile strategy to prepare high-performance wood adhesives aiming to meet higher applicational standard.

The most commonly used curing agents for soy-based adhesives are polyamines, which have the problem of low solid content and/or high viscosity. To overcome this problem, a new type of polyamidoamine (PADA) resin was synthesized and applied to soy flour-based adhesives to improve their water resistance. The PADA solution obtained had a high solid content of 50 wt% and low viscosity of 270 cP. The optimum weight ratio of soy flour/PADA/maleic anhydride to prepare adhesive was 40/7/1.68. The wet strength of plywood prepared at the optimum weight ratio was 0.82 MPa, which meant the plywood could be used as type II plywood according to the Chinese National Standard GB/T 9846.7-2004. The results of water-insoluble solid content measurement and SEM observation demonstrated that cured soy flour–PADA–maleic anhydride adhesive had a 16 % greater water-insoluble solid content than soy flour–NaOH adhesive. The cross-linking network formed by the reactions of PADA and MA would increase the water-insoluble solid contents and improve water resistance of cured soy flour-based adhesives.

Trypsin is used to remove non-collagenous proteins from cattle hide in leather processing but prone to damage hide surface and reduce leather quality due to its rapid protein hydrolysis action on the hide surface and slow penetration through the whole hide. A novel trypsin bating method was developed using a reversible inhibition of trypsin with high-yield, low-cost and environment-friendly soybean flour (SF). When the mass ratio of trypsin to SF was 1:20, the trypsin activity was decreased by 77 % at a reaction time of 5 min and completely returned in 100 min because of the competitive Kunitz trypsin inhibitor in SF. Bating with trypsin-SF mixture avoided the damage to hide surface caused by trypsin, improved the dispersion uniformity of hide collagen fibers and increased the softness and the mechanical strength of leather. This work exhibits huge potential for improving the leather quality and provides new insights into the soybean application.

This work studies the structural breakdown and nutrient release during in vitro digestion of soybean milk reconstituted from soybean flour with different particle sizes (> 100 mesh, 50–100 mesh, 28–50 mesh, 14–28 mesh and < 14 mesh). A clear effect of the particle size is noticed on the functional characteristics of the colloidal food during the gastric and intestinal digestion stages. In vitro gastric digestion significantly improves the release of polyphenols (21.4 ± 1.1–35.6 ± 3.2%, compared with the undigested one). In that stage, the antioxidant capacity increases between 20.8–38.5%, and is related to the particle size, hence free surface area, of soybean flour. Confocal microscopy shows that the proteins released from the soybean flour particles aggregate during gastric digestion, while the lipid droplets decompose down into smaller colloidal entities. Examination of the effect of particle size on the release of phenolic compounds, small molecule proteins/peptides, and fatty acids, showed that the highest amounts of the above substances existed when the particle size of soybean flour lies in the region of 50–100 mesh. This particle size also shows the highest bioaccessibility of the contained bioactive substances (polyphenols, 124.5 ± 0.5%; flavonoids, 49.1 ± 1.5%). These findings add insight on the role of the colloidal properties of the soybean flour with different particle sizes on the functionality of soybean milk.

Recent decades have witnessed an increasing trend of replacing conventional formaldehyde-based adhesives with sustainable and ecofriendly biobased adhesives in the commercial wood industry. The present study developed a full biomass utilization design for adhesives consisting of a cheap soybean meal and a lignin-based crosslinking agent (EXL). The primary component of the latter, i.e., epoxidized lignin, was synthesized using alkaline lignin and epichlorohydrin under simple reaction conditions. The Fourier transform infrared, proton nuclear magnetic resonance, and carbon-13 nuclear magnetic resonance analyses revealed the epoxy characteristic peaks in EXL, further validating the efficacy of the design developed. This simple design successfully synthesized the EXL with more epoxy groups. Moreover, a fully biobased adhesive with a wet bonding strength of up to 0.96 MPa was produced by incorporating the EXL as a sole crosslinking agent, which satisfies the requirements for interior plywood use. Furthermore, the effect of the lignin-based crosslinking agent with more epoxy groups on the structural changes, thermal stability, and micromorphology of the resulting adhesive was investigated. The incorporation of EXL exhibited a beneficial impact on the soy adhesive with improved wet bonding strength and thermal stability. Additionally, the antimold observation experiment under a high humidity environment demonstrated that the EXL contributed to the excellent antimold performance of the adhesive.

The development of microbial fuel cells (MFCs) into a new type of carbon-neutral wastewater treatment technology requires efficient and low-cost oxygen reduction reaction catalysts in air cathodes. The use of raw soybean powder was investigated for synthesizing Fe–N–C ORR catalysts in a sacrificial SiO 2 support method. ZnCl 2 etching in the synthesis was found to facilitate the formation of hierarchical porous structures of Fe–N–C catalysts. Fe–N–C(1-1) catalyst synthesized with an optimal soybean/ZnCl 2 mass ratio of 1:1 exhibited the highest ORR activity in air cathodes. The use of the obtained Fe–N–C(1-1) catalyst enables a maximum power production of ~0.480 mW cm −2 in MFCs, higher than commercial Pt/C (0.438 mW cm −2 ) with the same catalyst loading of 2 mg cm −2 . Long-term MFC operations demonstrated that the Fe–N–C synthesized from raw soybean have high stability and toxic tolerance, indicating that abundant low cost soybean biomass is a potential material for ORR catalyst development in MFC applications.

The depletion of fossil resources and the emission of harmful substances have spurred the need for biomass-based adhesives. Soybean meal, a renewable and eco-friendly material, offers a promising alternative to petroleum-based adhesives in wood products. However, water evaporation during curing often reduces the wettability and bond strength of soybean meal-based adhesives. Inspired by highly absorbent polymers, a soybean meal-based adhesive with enhanced water retention was developed by constructing multiple cross-linking networks and promoting hydrogen-bonding interactions between polyacrylamide (PAM) and thiolated sodium alginate (SASH). Notably, the SM-SASH-PAM5 adhesive retained 56% of its mass after 24 h in an open environment, prolonging its lifespan. The thinner adhesive layer (SM-SASH-PAM5) retained more than 76% of its mass after 30 min in a dry environment while maintaining 75.7% of its initial wet shear strength. In addition, it showed a 297.22% improvement in wet shear strength, reaching 1.07 MPa, and a 516.67% increase in prepressing bond strength, achieving 0.93 MPa compared to the original soybean meal adhesive. This strategy provides a versatile method for developing adhesives with excellent water retention, suitable for practical manufacturing applications.

Germination and heat processing can improve the digestibility of soybean protein, so for the elderly and people with gastrointestinal dysfunction, instant soybean powder is an ideal source for protein intake. In this study, the changes in protein and anti-nutritional factors in the instant germinating soybean powders were investigated systematically, and the aged gastrointestinal digestion model analyzed the digestive characteristics of instant germinating soybean powders. The results showed that during processing, particle size, disulfide bond, and β-sheets decreased, free sulfhydryl and α-helix increased. The change resulted in the decrease of proteolysis degree and particle size of gastrointestinal digestive products, and the increase of surface hydrophobic index. At the same time, anti-nutritional factors decreased by about 30 % to 60 %. The above reasons are combined with the protein digestibility of S 72 5.88 % higher than Y 0 . This study proved that instant soybean powder is more conducive to the digestion and absorption of the elderly.

The main aim of this work is to prepare a high-temperature soybean meal (HSM) wood adhesive with excellent water resistance and prepressing adhesion to satisfy the requirements of green wood-based composites. Different from traditional complex modification methods, a lignosulfonate (LS)-assisted thiol-grafted polyamide-epichlorohydrin (PAE-SH) reinforced HSM wood adhesive was developed via a simple and novel design. The reduced –SH groups were grafted onto polyamide-epichlorohydrin (PAE) to break the S–S in HSM proteins and prompt a disulfide bonds rearrangement between PAE-SH and protein. LS was then introduced into PAE-SH to induce multiple crosslinking interactions, including cation-π interactions and electrostatic interactions. The generation of the LS-assisted PAE-SH not only contributed to the formation of a stable multiple cross-linked adhesive system for strong cohesion, but also provided a suitable solid content of adhesives for the formation of mechanical nail in plywood veneers. The plywood bonded using the PAE-SH/LS-modified adhesive displayed a wet bonding strength of 1.41 MPa, which is 402.9% higher than that of the neat soybean meal adhesive. It was also showed a prepressing bonding strength of 548 kPa, which is more than twice of the pure HSM-based adhesive (245 kPa), greatly reducing the transportation difficulty of veneers before being hot-pressed. This study provides a novel strategy for preparing a water-resistant protein-based adhesives with great potential for industrial application.
