The soybean residue (okara) with high moisture content has generally been discarded, which has led to economic loss and socio-environmental problems. The effects of solid state fermentation using Kluyveromyces marxianus on the nutritional components, beany odor and processing properties of soybean residue were studied. The results showed that K. marxianus fermented soybean residue (FSR) had an increase in crude fat (24.5%), soluble dietary fibers (158%) and polysaccharides (262%), while phytic acid (61.7%) and the activity of a trypsin inhibitor (92.7%) decreased. A significant reduction in the beany odor was also observed. FSR showed higher water absorption and better emulsifying properties. Overall, the study indicated that fermentation with K. marxianus resulted in improved nutritional values and processing characteristics of the soybean residue.

In this study, pectin polysaccharide (SDPP) was obtained from soybean dreg (26.2% yield), and characteristics of SDPP were compared with those of soybean soluble polysaccharides (SSPS) and citrus pectin (HMP). The galacturonic acid and molecular weight of SSPS, SDPP or HMP were 11.8%, 40.6% or 70.2% and 112, 446, or 440 kDa. SDPP had similar viscosity and protein content to SSPS, and functional groups and linear structure to HMP. SSPS, SDPP or HMP differed in particle size of 260, 467 or 1195 nm and ζ–potential of −5.8, −14.6 or −23.5 mV at pH 4.0. The precipitation of acidified milk drink (AMD) was 6.31% without stabiliser or below 1.75% with 0.4% SDPP at pH 3.6–4.6. These results suggested that SDPP combines the structure and characteristic of HMP and SSPS, and AMD with SDPP had great stabilising behaviour at wider pH range (pH 3.6–4.6).

Nowadays, high-performance electromagnetic wave (EMW) absorption materials derived from low-cost biomass materials have attracted widespread attention. Herein, a novel biomass‑carbon with porous array structures derived from waste soybean dregs is prepared by a hydrothermal method combined with heat treatment using formaldehyde and KOH as activators. The as-prepared biomass‑carbon with significantly enhanced specific surface area can possess more charge transmission paths, increased multiple reflections and scattering, multiple loss modes, and improved impedance matching, leading to the improvement of EMW absorption performances . The obtained single-component biomass‑carbon without any functional fillers exhibits an effective EMW absorption capability with a wide absorption bandwidth of 4.8 GHz at a thickness of 3.5 mm. This study will provide a valuable approach for the preparation of biomass‑carbon based EMW absorption materials with controllable porous structures by the activation process .

The contamination of mycotoxin in edible oil has always been a major threat to human health. In this study, magnetic soybean dreg-based biochar SDB-6-K-9@Fe 3 O 4 was prepared via co-precipitation and used to remove aflatoxin B1 (AFB1) from contaminated oil. The adsorbent characterization results revealed that the Fe 3 O 4 was successfully loaded to the SDB-6-K-9. The 0.45SDB-6-K-9@Fe 3 O 4 had paramagnetic properties with a saturation magnetization of 45.15 emu/g, which could be quickly separated from the peanut oil using an external magnet. The maximum adsorption capacity of peanut oil contaminated with 200 ng/mL AFB1 by 50 mg 0.45SDB-6-K-9@Fe 3 O 4 for 2 h reached 0.1354 mg/g, while the removal process minimally affected the quality of the oil. The adsorption behavior results followed a pseudo-second-order kinetic and fitted well with the Freundlich model. The excellent adsorption removal efficiency and facile magnetic separation of the adsorbents provide a simple and efficient method for removing contaminants from the oil.

Soluble polysaccharides derived from microbial fermentation of agricultural by-products were considered as potential functional ingredients, primarily having probiotic properties. Herein, soluble polysaccharides (FSRP) were isolated from soybean residue fermented by Neurospora crassa, and FSRP mainly contained rhamnose, arabinose, fucose, mannose, glucose, and galactose, according to GC-MS analysis. To further investigate the protective effect of FSRP against colitis, dextran sulfate sodium induction (DSS)-treated mice were orally gavaged with FSRP (200 mg kg−1 d−1) or inulin (400 mg kg−1 d−1, a positive control) for 7 d. The results showed that DSS-treated mice displayed symptoms of body weight loss, atrophy, and histopathological changes of colon, as well as gut barrier damage, which were recovered after FSRP supplementation (similar to inulin). Furthermore, the beneficial effects of FSRP were linked to a decreased inflammatory response and increased protein expression of E-cadherin, claudin-1 and ZO-1. Illumina-MiSeq sequencing analysis revealed that FSRP increased microbial diversity and altered community structure. Specifically, FSRP could modulate the abundance of inflammation-related bacteria (such as Tenericutes, Clostridia, and Bacilli) to ameliorate colitis symptoms. Therefore, FSRP can relieve DSS-induced colitis, which is closely associated with reduced levels of inflammatory factors, improved gut barrier function and gut microbiota homeostasis.
