Soybean meal or bean pulp is the residual waste obtained after extraction of oil from soybean flakes. This residue has gained significant interests because of its high nitrogen content. In this study, a one-step pyrolysis synchronous activation method has been proposed for preparing nitrogen-doped hierarchical porous bean pulp carbon (BPC) in a CO 2 environment. The morphological, structural, and crystallisation properties of the BPC are adjusted by changing the treatment temperature. The BPC coated with MnO 2 (BPC@MnO 2 ) nanoparticles are further synthesised in a straightforward manner using a green hydrothermal method. The produced samples are evaluated as electrode materials for supercapacitor application. The results show that the pore structure and nitrogen species of biochar are strongly affected by the presence of CO 2 and pyrolysis temperature. The coated MnO 2 nanoparticles can be uniformly deposited on the surface of the BPC. The electrochemical performance of the BPC@MnO 2 composite is higher than that of the BPC. A specific capacitance of 288.3 F/g can be attained for the BPC@MnO 2 at the current density of 0.25 A/g. The symmetrical button capacitor made from the composite successfully lights up the light-emitting diode for more than 300 s. These novel electrode materials derived from bean pulp display considerable potentials for application in energy storage.

Soybean dregs fermented by Neurospora crassa is a typical traditional food in Gannan district of China. In this study, in vitro imitated gut fermentation was carried out to evaluate whether the oligosaccharides from this fermented soybean dregs had potential prebiotic properties. 11.91% of oligosaccharides were extracted from the fermented soybean dregs at the optimized condition which of 1:25 for ratio of soybean dregs (g) to 50% ethanol (ml), 90 min of extracted duration at 70 °C for twice. The soybean dreg oligosaccharides (SBOS) were progressively purified with Sevag method and on columns filled with AB-8 macroporous resin, and then identified as cellobiose by HPLC-ESI-MS and FT-IR. Oligosaccharides of soybean dregs with 800 mg/L significantly decreased pH value ( p < 0.05) and ammonia N concentration ( p < 0.05), and increased short chain fatty acid (SCFA) level ( p < 0.05) in imitated gut fermentation compared with control group. It was shown that this fermented soybean dregs could be a potential prebiotic food.

Converting waste resource into porous carbon toward contaminant capturing is a crucial strategy for realizing “treating waste with waste”. Inspired by bread baking process, the soybean meal activated carbon (SAC) with multimodal pore structures was developed via thermally remodeling the pores of waste soybean meal. The obtained SAC-3-800 has ultra-high specific surface area (3536.952 m 2 /g), as well as a hierarchically porous structure. SAC-3-800 exhibits extremely high adsorption capacity for methylene blue (MB) (3015.59 mg/g), methyl orange (MO) (6486.30 mg/g), and mixed dyes (8475.09 mg/g). The hierarchically porous structure enabled fast adsorption kinetics of SAC-3-800 for MB and MO (∼30 min). Additionally, SAC-3-800 shows excellent dynamic adsorption and regeneration performance, exhibiting great potential for industrial applications. This work showcases a feasible method for synthesizing hierarchically porous carbon with outstanding adsorption performance that can simultaneously achieve efficient treatment of dye-wastewater and value-added utilization of waste resources.

This study aimed to reveal the impact of excessive dietary fibre (DF) intake on inflammatory responses and bile acid (BA) homeostasis in largemouth bass ( Micropterus salmoides ) and the potential mechanism. In vitro BA binding capacity was compared, and the results showed that the BA binding capacity to chenodeoxycholic acid and glycocholic acid by pectin and soybean meal was higher than cellulose and cottonseed meal respectively. An in vivo trial was conducted using a diet without DF as a control (CON diet), while test diets contained 150 g/kg cellulose (CEL diet) or pectin (PEC diet), 500 g/kg soybean meal (SBM diet) or cottonseed meal (CSM diet). Fish were overfed and ate ad libitum . Compared to fish fed the CON diet, fish fed the PEC and SBM diets showed high expression of inflammatory factor genes and BA synthesis factor genes and obvious histopathological damage in the gut and liver, while the responses of fish fed the CEL and CSM diets were mild. Whole-body BA contents in fish fed all test diets were lower than those in fish fed the CON diet ( p < 0.05). These results support the hypothesis that excessive DF intake induces inflammatory responses and dysregulation of BA homeostasis, which might be attributed to their binding capacity to BAs.

Currently, dry fractionation is employed to extract dietary fiber (DF) from food processing bypuroduct owing to its advantages of low energy and eco-friendly. Procedures of dry fractionation mainly include milling and air classification. Soybean meal (SBM) is a processing byproduct rich in DF. Few studies have used dry fractionation to extract SBM dietary fiber (SMF), and the physicochemical properties, structural characteristics, and activity of SMF extracted via dry fractionation remain unclear. Herein, SMF was prepared via dry fractionation and results showed that compared with that of SBM without pores and high crystallinity, SMF had loose and porous surface and low crystallinity. Moreover, the water holding capacity, oil holding capacity and swelling ability of SMF were significantly higher than SBM. After 24 h of in vitro fecal fermentation, the SMF group produced abundant short chain fatty acids (SCFA) such as acetic, propionic, and butyric acids and the total SCFA production was substantially higher than that in the inulin (INL) group. SMF also promoted the relative abundance of beneficial bacteria such as Prevotella , Dialister , and Bifidobacterium and reduced the relative abundance of harmful bacteria such as Escherichia–Shigella . In conclusion, SMF extracted via dry fractionation can significantly alter the relative abundance and diversity of gut microbiota and promote the production of SCFA, which is conducive to the regulation of the human gut microbiota. This study can provide insights into the preparation of DF via dry fractionation and provide theoretical basis for SMF to be used as a prebiotic.

In this study, Rhizopus oligosporus RT-3 was utilized to ferment soybean meal to obtain a tempe-like food with low fat and high bioactivity. To investigate the impact of fermentation on soybean meal’s nutritional value, we detected the protein-related indices and conducted a non-targeted metabonomic analysis on both fermented soybean meal (FSM) and soybean meal (SM) in order to explore changes in a certain type of metabolite and its corresponding metabolic pathways. The results showed a significant increase in crude protein, peptides and amino acids while getting porous after fermentation. A reduction of raffinose and stachyose to 18.1% and 8.5%, respectively, due to the action of α-galactosidase and β-furanofructosidase occurred. As to amino acid metabolites, essential amino acids for human bodily functions such as lysine, histidine, and threonine were significantly upregulated. Furthermore, nine peptide metabolites were identified as angiotensin-converting enzyme (ACE) inhibitors and dipeptidyl peptidase-4 inhibitors (DPP-IV). After feeding with different doses of FSM, levels of insulin-like growth factor-1 (IGF-1), hemoglobin (HB), albumin (ALB), and total protein (TP) of malnourished mice all returned to normal. In conclusion, fermentation with Rhizopus oligosporus RT-3 can improve the quality of SM by reducing the level of oligosaccharide anti-nutrition factors and increasing the contents of free amino acid and small bioactive peptides, which provide a theoretical basis and new ideas for the application of FSM.

Developing low-cost renewable bio-based adhesives with excellent properties remains a challenge. Soybean meal (SM) adhesives have gained widespread attention for being green. However, it still has the problems of poor water resistance, low toughness, and easy to mildew. Herein, a waterborne polyurethane (TWPU) with carboxyl side chains was synthesized from tartaric acid (TA). It was used as chelating ligands to form the metal chelating to synergistically modify (SM) adhesives. This overall improved the adhesives bonding strength , toughness and water resistance. The coordination interactions between the polyurethane molecules and the protein molecules of SM were formed by multi-crosslinking via metal chelating, covalent bonding, and hydrogen bonding to enhance the adhesive's toughness, bonding strength and water resistance. As a result, the wet bond strength and toughness of the modified SM adhesives were 166.7 % and 275.3 % higher than blank sample, respectively, reaching 1.29 MPa and 0.61 J. Considering of the used raw materials and synthesis method in our process are simple and widely available, this study provides an eco-friendly and effective method for green, low-cost, and high-performance wood-based composite adhesives.

A novel gene ( BbFFase9 ), with an ORF of 1557 bp that encodes β-d-fructofuranosidase from Bifidobacteriaceae bacterium , was cloned and expressed in Escherichia coli . The recombinant protein (BbFFase9) was successfully purified and showed a single band with a molecular mass of 66.2 kDa. This was confirmed as a β-d-fructofuranosidase and exhibited a high specific activity of 209.2 U/mg. Although BbFFase9 was a soluble protein, it exhibited excellent tolerance to proteases such as pepsin, trypsin, acidic protease, neutral protease and Flavourzyme®, indicating its potential applicability in different fields. BbFFase9 exhibited typical invertase activity, and highly catalyzed the hydrolysis of the α1↔2β glycosidic linkage in molecules containing fructosyl moieties but with no detectable fructosyltransferase activity. It was optimally active at pH 6.5 and 50 °C and stable between pH 6.0 and 9.0 at a temperature of up to 45 °C for 30 min BbFFase9 could also effectively hydrolyze galacto-oligosaccharides, which are a flatulence factor in soybean meal, thus releasing new types of product such as melibiose and mannotriose, or degrading them into invert sugars, the sweeter fructose and glucose. This study is the first to report the application of this type of β-d-fructofuranosidase.

This study investigated the effects of Clostridium butyricum (CB) and sodium butyrate (SB) on the growth performance, intestinal immune, and gut microbiota of mirror carp ( Cyprinus carpio ) fed with a high level of soybean meal. Three hundred sixty healthy carp fingerlings (∼3.74 g) were divided into eight dietary treatments with four replicates and ten fish per replicate. Which include basal diet (Control group, C0); C0 supplemented with three levels of CB, 3 × 10 7 cfu/kg (C1), 3 × 10 8 cfu/kg (C2), 3 × 10 9 cfu/kg (C3); three levels of SB, 500 mg/kg (S1), 1000 mg/kg (S2), 2 000 mg/kg (S3); and 3 × 10 8 cfu/kg CB+ 1 000 mg/kg SB (CS), respectively. In 8-week trial, the survival rate of all groups was 100%. Compared with C0, the Weight Gain, Feed Conversion Ratio, Protein Efficiency Ratio were not significantly different in all groups ( P > 0.05). Crude protein and ether extract contents were increased significantly ( P < 0.05) when supplemented with different levels of CB and SB, and ash content increased significantly in the CB groups ( P < 0.05). Serum globulin increased and glucose decreased significantly ( P < 0.05) in the CB and SB groups. The intestinal T-SOD and glutathione activity in the foregut, midgut, and hindgut were increased ( P < 0.05), and villus height of foregut and midgut were higher in the CB and SB ( P < 0.05). Protease activities in the foregut and midgut were significantly increased ( P < 0.05) in the C2, C3, S2, and S3. The lipase activity of the C2 and C3 in foregut, midgut, and hindgut; S2, S3, and CS in the foregut; S3 in midgut were significantly increased ( P < 0.05). The gut microbiota was modulated at the phylum and genera level by CB and SB administration. In summary, our results indicated that CB and SB could promote the whole body CP and EE content, intestine immunity, digestive enzyme activity, and intestinal morphology, and modulated gut flora in carp.

Hydrothermal treatment is a beneficial method for the resource utilization of biomass waste, producing hydrochar and an aqueous phase containing valuable organic products. However, the pathway for recovering high-value products from the aqueous phase remain insufficiently explored. This work presents an innovative enzymatic-hydrothermal treatment designed to enrich the concentration of nitrogen-containing compounds in the hydrothermal aqueous phase (AP) derived from nitrogen-rich biomass. A detailed analysis of the post-enzymatic AP products was carried out, with a specific emphasis on tracking changes in the chemical composition of the AP. The results showed a significant increase in the nitrogen content of the soymeal-derived AP after enzymatic pre-treatment followed by hydrothermal treatment at 220 °C. Meanwhile, valuable platform compounds such as furfural and 5-hydroxymethylfurfural were produced via isophorone-catalyzed decarboxylation of α-amino acids within the enzymatic soymeal AP, steered by deliberate modifications in the reaction pathway. Moreover, a working mechanism for this catalytic decarboxylation process was proposed, enabling precise adjustments to the composition of the AP.

In the present work, we prepared Maillard reaction products (MRPs) derived from enzyme hydrolyzed soybean meal with ultrasound assistance in an oil-(oxidized lard)-in-water system (UEL-MRPs) or oil-free system (UN-MRPs), and the effect of ultrasound on the properties of the obtained MRPs was evaluated. The analysis of fatty acids in lard with different treatments showed that ultrasound can generate more unsaturated fatty acids in the aqueous phase. The UV–Vis absorbances of UEL-MRPs, UN-MRPs, and MRPs obtained in an oil-in-water system (EL-MRPs) and MRPs obtained in an oil-free system (N-MRPs) at 294 and 420 nm indicated that ultrasound could increase the amount of Maillard reaction intermediates and melanoids in the final products of the Maillard reaction. This was in line with the result obtained from color change determination—that ultrasound can darken the resultant MRPs. Volatile analysis showed ultrasound can not only increase the number of volatile substances, but also greatly increase the composition of volatile substances in UEL-MRPs and UN-MRPs, especially the composition of those contributing to the flavor of the MRPs, such as oxygen-containing heterocycles, sulfur-containing compounds, and nitrogen-containing heterocycles. Descriptive sensory evaluation revealed that UN-MRPs and UEL-MRPs had the highest scores in total acceptance, ranking in the top two, and UEL-MRPs had the strongest meaty flavor among these four kinds of MRPs. Furthermore, the measurements of antioxidant activities, including DPPH radical-scavenging activity, hydroxyl radical scavenging ability, and ferric ion reducing antioxidant power, were conducted, showing that UN-MRPs exhibited the highest antioxidant activity among all the MRPs.Keywords:Maillard reaction;ultrasound;hydrolyzed soybean meal;oxidized lard

An 8-week feeding trial was conducted to evaluate the effect of fish-meal replacement on growth performance, whole body composition, apparent digestibility coefficients and anti-oxidative ability of juvenile Pacific white shrimp , Litopenaeus vannamei . Five practical diets were formulated to contain graded levels (5, 10, 15, 20 and 25%) of fish-meal. Soy protein concentrate and soybean meal based protein blend was used to replace fish-meal, amino acids were supplemented in the low fish-meal diet to get similar amino acid profile as the high fish-meal diet. Weight gain, survival, feed conversion rate (FCR), feed intake and protein efficiency ratio (PER) did not show any significant differences between any of the groups. Alanine ratio in whole body were higher in shrimp fed high fish-meal diets while arginine decreased with the increasing fish-meal levels. The Fe content in whole body was significantly lower in shrimp fed the low fish-meal diets, while the other minerals showed no difference among all the groups. Apparent digestibility coefficients (ADC) of dry matter, protein, Ca, P, Cu, Zn and Mg were equal in all the treatments, while ADC of Fe decreased with the decreasing fish-meal levels. When dietary fish-meal decreased, the anti-oxidant related enzymes activity (Total antioxidant capacity (T-AOC) and Catalase (CAT)). Superoxide dismutase (SOD) was unaffected by treatments. Nitric oxide (NO) contents in hemolymph significantly decreased with the decreasing fish-meal levels, while Phenoloxidase (PO) was unaffected. The results indicated that growth performance and apparent digestibility coefficients of nutrients were not affected when fish-meal was replaced from 25% to 5%, but anti-oxidative ability and immune response were damaged after fish-meal level decreased to 15%. Statement of relevance The results of this manuscript contribute to the commercial feed industry of white shrimp, it will be helpful in fish meal replacement, which is very important to the sustainable development of aquaculture.
