Removing textile dye by activated carbon adsorption from wastewater has become a focus issue owing to its easy operation, rapid adsorption ability, and relatively high removal efficiency. Biomass-based activated carbon is an excellent candidate due to its renewability and easy accessibility, but the biomass resources like peel and stem are usually with relatively long growth cycle and the removal efficiency within a wide pH range is relatively low. Thus, a biomass carbon source with a short growth cycle and activated carbon with high removal efficiency within a wide pH value needs to be explored. In this study, golden needle mushroom root-based activated carbon (GNMACs) activated by H 3 PO 4 was successfully prepared, characterized, and applied in methylene blue (MB) and methyl orange (MO) removal. The carbonization temperature (400 °C ∼ 600 °C), the GNMACs dosage (5 mg ∼ 25 mg), and the dye solution pH (4 ∼ 12) were controlled. The results indicated the optimal adsorption performance can be achieved with the carbonization temperature of 550 °C and the adsorbent dosage of 20 mg. The GNMACs carbonized at 550 ℃ possessed a porous structure with the mesopore volume of 1.095 cm 3 /g, the specific surface area of 802.987 m 2 /g, and the average pore diameter of 5.87 nm. Within a wide pH range from 4 to 12, GNMACs removed MB with an efficiency above 98.57 % and MO with an efficiency above 98.77 %. Additionally, the adsorption process of MB and MO onto GNMACs followed the pseudo-second-order kinetic model and the Redlich-Peterson isothermal adsorption model, with adsorption capacities of 816.04 mg/g and 286.99 mg/g, respectively. The adsorption was facilitated by hydrogen bonding, electrostatic attraction, π-π interaction, and pore filling. The results indicated the GNMACs can be used as an adsorbent to remove MB and MO from the wastewater.

Flammulina velutipes has anti-inflammatory, immunomodulatory, antioxidant and many bioactive properties with high contents of carbohydrate, proteins and fibers. In this study, a novel proteoglycan with polysaccharide complexes and protein chain, named PGD1-1, was isolated from F. velutipes . The structural characteristics of PGD1-1 were then determined, and its anti-proliferation and pro-apoptotic activities against HepG-2 cells were demonstrated in vitro. Results proved that the average molecular weight of PGD1-1 was 32.71 kDa, and the carbohydrate and protein contents were 93.35 and 2.33%, respectively. The protein moiety was bonded to a polysaccharide chain via O-glycosidic linkage. The monosaccharides consisted of d -glucose, D-galactose and D-xylose in a molar ratio of 21.90:2.84:1.00. PGD1-1 significantly inhibited the proliferation of HepG-2 cells by affecting cell lipid peroxidation and nitric oxide production. In addition, PGD1-1 promoted the apoptosis of HepG-2 cells, especially the early apoptosis. These findings proved that PGD1-1 was a novel potent ingredient against the proliferation of HepG-2, which will provide a theoretical basis for the development and utilization of the functional ingredients of the F. velutipes .

The golden mushroom ( Floccularia luteovirens ), a nutritionally valuable edible fungus endemic to the Qinghai-Tibet Plateau, exhibits significant quality heterogeneity across different geographical origins. This study employed ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q/ToF-MS)-based metabolomics integrated with multivariate analyses to authenticate specimens from Ganzi (Sichuan, SC), Haibei (Qinghai, QH), and Naqu (Xizang, XZ). Principal component analysis (PCA; Q 2 > 0.98, R 2 Y > 0.99) and partial least squares discriminant analysis (PLS-DA; Q 2 > 0.98, R 2 Y > 0.98) confirmed robust geographical discrimination, identifying 52 lipid-dominated markers as critical discriminators. Region-specific markers included triacylglycerols (TG)(54:6), phosphatidylinositols (PI)(18:2/18:2), phosphatidic acids (PA)(18:2/18:2), diacylglycerols (DG)(33:3), and bioactive compounds (e.g., N -linoleoyl-γ-aminobutyric acid, epoxymurin A) in XZ; phosphatidylcholines (PC)(16:0/18:2), lysophosphatidylserines (LysoPS)(16:0), ergocalciferol, and hydroxylated fatty acids ((9Z,12Z)-15,16-dihydroxyoctadeca-9,12-dienoic acid (dihydroxyoctadecadienoic acid, DiHODE), 2-β-methoxy-1-α,25-dihydroxyvitamin D 3 ) in QH; and cerebrosides, ceramides (Cer)(t20:0/22:0(2OH)), and saturated lipid derivatives (PA)(24:0/24:0) in SC. Nutritional profiling revealed that XZ had the highest unsaturated fatty acid content (49.94 %) and hydroxyl radical scavenging capacity (18.34 %/mg), whereas QH exhibited superior 2,2-diphenyl-1-picrylhydrazyl (DPPH) inhibition (87.62 %/mg). Lipidomics analysis indicated that XZ's lipid profile was enriched in polyunsaturated species (e.g., 9-hexadecenoic acid, tricosanoic acid), while QH was characterized by omega-3 fatty acids (9,12,15-octadecatrienoic acid) and SC by medium-chain fatty acids (decanoic acid). Key biochemical differences included peak crude and soluble protein levels in XZ (433.5 mg/g and 83.96 mg/g, respectively), whereas QH exhibited the highest free amino acid content (37.58 mg/g). Hydrolyzed amino acid composition varied by region, with SC displaying the lowest leucine (Leu) and alanine (Ala) concentrations. In terms of polysaccharide and polyphenol contents, SC contained the highest polysaccharide levels (116.72 mg/g), whereas QH had the highest polyphenol content (3.64 mg/g). Antioxidant assays further validated origin-dependent bioactivity, with XZ exhibiting the strongest hydroxyl radical scavenging activity, while SC displayed the lowest DPPH/ABTS activities (73.91 %/mg; 0.2 nM trolox/mg) and FRAP values (0.31 mM FeSO 4 /mg). This metabolomics-driven framework establishes a reliable tool for geographical authentication, supporting quality control and the sustainable utilization of golden mushroom resources in functional food industries.

Modified dietary fiber has shown great application potential in the fields of nutrition, food science and health. The aim of this study is to investigate the modification of dietary fiber of Flammulina velutipes by extrusion and expansion technology and cellulase. The differences of gut microbiota, SCFAs (short-chain fatty acids) and lead ion stress between FDF (Dietary Fiber from Flammulina velutipes ) and MFDF (Modified Dietary Fiber from Flammulina velutipes ) were clarified in vitro fermentation. The results demonstrated that the extrusion-cellulase technology could effectively reduce the molecular weight of FDF, adjust the monosaccharide composition and change the micromorphology. In vitro microbial fermentation results showed that FDF and MFDF adjusted the composition of gut microbiota, increased excellent lead ion adsorption capacity of intestinal flora, promoted the production of acetic acid, propionic acid, and n-butyric acid, increased the presence of beneficial bacteria such as Macrophages , Bifidobacterium , Faecalibacterium , and Mitsuokella , and reduced the levels of harmful bacteria such as Escherichia Shigella and Salmonella . In comparison, MFDF also showed better lead ion adsorption capacity of intestinal flora, produced more SCFAs and more significant biomarkers, highlighting a potential gut prebiotic role. This study provides valuable data support for the modified application of innovative processing techniques to edible fungi and highlights the potential application of dietary fiber-related functional products to promote gut health.

This study investigated the interaction mechanisms between rice starch (RS) and two different Flammulina velutipes polysaccharides (FPs) obtained through water-extracted (WEFP) and alkali-extracted (AEFP) methods regarding the pasting, gelatinization, retrogradation, and in vitro digestive properties. The WEFP, with a majority of α-glucan and lower MW, and the AEFP, a high MW trihelix β-glucan, distinctly affected the physicochemical and digestive properties of RS in a dose-dependent manner. Both FPs reduced the leached amylose content, retrogradation, and digestibility of RS, and increased the shear stress, storage modulus, and loss modulus of RS. The swelling power and pasting viscosities of RS were inhibited by WEFP and enhanced with AEFP. Compared with the control RS gel, WEFP increased the gelatinization temperatures while AEFP accelerated the gelatinization of RS. Fourier-transform infrared analysis revealed WEFP enhanced the hydrogen bonding with starch and water molecules which increased the short-range ordered structures, and a more compact, wrinkle, and ordered network structures could be visualized in RS-WEFP gel, which attributed to the decreased glycemic responses of RS-WEFP gels. However, reduced hydrogen bonds were observed in RS-AEFP systems, and entanglement effect of viscous AEFP on starch granules resulted a thicker and more disordered RS-AEFP gel structure, which was the main factor restricted the digestion rates of RS. This study provides a theoretical insight about the application of FPs on RS-based hypoglycemic foods.

Fresh mushrooms ( Flammulina velutipes ) are very perishable and easily brown; also they undergo postharvest loss of nutritive constituents. In this study, cinnamaldehyde (CA) emulsion was prepared by using soybean phospholipids (SP) as emulsifier and pullulan (Pul) as stabilizer. The effect of emulsion on the quality of mushroom during storage was also studied. The experimental results indicated that the emulsion obtained by adding 6 % pullulan was found to the most uniform and stable, which is beneficial to its application. Emulsion coating maintained the storage quality of Flammulina velutipes. The incorporation of CA emulsion into the coating system showed a positive effect on inhibiting the accumulation of reactive oxygen species, resulting from improving the effectiveness of delaying active free radical scavenging enzymes . The shelf life of mushrooms coated with emulsion was significantly prolonged, which indicates its potential application in food preservation.

Cadmium (Cd), as Group I carcinogen, can induce damage to various organs including the gut. It is of great importance to meet the rising demand for effective therapies against Cd-induced damage and investigate the mechanism. Flammulina velutipes is a popular edible mushroom, despite the well-known health benefits of Flammulina velutipes , little is known about the effect of its polysaccharide (FVP) against CdCl 2 -intestinal injury. In this study, a FVP (uronic acid, 5.10 %; degree of methylation, 41.24 %) was produced via hot water extraction (85 °C) and ethanol precipitation. The FVP contained eight major monosaccharides and exhibited good thermal stability at temperatures lower than 139.73 °C. FVP (100 mg/kg b. w., gavage for 4 weeks) alleviated CdCl 2 (1.5 mg/kg b. w., gavage for 4 weeks)-induced intestinal inflammation and apoptosis, intestinal permeability alteration and intestinal barrier disruption. FVP increased the abundance of Bacteroides , whilst decreasing the abundance of Desulfovibrionales and Clostridium . FVP also restored the levels of short-chain fatty acids (SCFAs), including acetic, propionic, isobutyric, butyric, isovaleric and valeric acids. Correlation analysis indicated the interplays among the FVP, gut microbes, SCFAs, intestinal barrier/cells and gut inflammation. FVP enhances the metabolic functions of gut microbiota via functional pathways analyzed by KEGG database. Furthermore, gut microbial transplantation of FVP + CdCl 2 group mice partially alleviated CdCl 2 caused-gut damage. Thus, FVP may be an effective therapeutic agent against CdCl 2 -induced gut damage via SCFA-mediated regulation of intestinal inflammation and gut microbiota-related energy metabolism. This study may open a new avenue for developing alternative strategies to prevent CdCl 2 -caused injury.

Flammulina velutipes residues, the by-products of Flammulina velutipes industry, cause environmental pollution. The aim of the current work was to evaluate the extraction efficiency of polysaccharides from Flammulina velutipes residues by an ultrasonic assisted snailase enzymatic extraction (UAEE) method, following the principles of green chemistry, mainly solvent and energy saving. The optimized parameters obtained by Response Surface Methodology (RSM) were determined as follows: ultrasonic power at 150 W, extraction time of 90 min, and extraction temperature of 55 °C. The experimental extraction yield (109.54 ± 5.44 mg/g) was closely matched the predicted yield (110.92 mg/g). Polysaccharides from Flammulina velutipes residues (UE-FVRP) had the molecular weight of 170 kDa and a composition comprising 8 monosaccharides, primarily xylose (Xyl, 24.71%), mannose (Man, 17.29%), arabinose (Ara, 11.48%), and galactose (Gal, 15.63%). FT-IR analysis suggested that UE-FVRP likely contained pyranose with α-glycoside bonds. In vitro antioxidant activity assays revealed that UE-FVRP displayed potent DPPH radical scavenging activity and reducing ability. Additionally, UE-FVRP demonstrated the ability to promote the growth of two Lactobacillus strains, indicating its potential as a novel polysaccharide with high in vitro prebiotic properties. Therefore, these findings proposed a novel, green, and efficient extraction method for extracting polysaccharides from Flammulina velutipes residues, highlighting the potential of utilizing Flammulina velutipes residues as a valuable ingredient in both food and feed applications, contributing to the sustainable reuse of agricultural by-products.

Adhere to the concept of low-carbon environmental protection and turning waste into treasure, polysaccharides from Flammulina velutipes residue polysaccharide (FVRP) has been developed and possesses diverse bioactivities, comprising antioxidant, hypoglycemic, and relieving heavy metal damage, which still has the disadvantages of high molecular weight and low bioavailability. The current work is the first to prepare a degraded polysaccharide (FVRPV) from FVRP by ultrasonic assisted H 2 O 2 -Vc technique in order to reduce its molecular weight, thereby improving its activity and bioavailability. Our results found that the molecular weight and average particle size were declined, but the monosaccharide composition and characteristic functional group types of FVRPV had no impact. The structural changes of polysaccharides analyzed by XRD, Congo Red test, I 2 -KI, SEM, and methylation analysis indicated that the surface morphology and glycosidic bond composition of FVRPV possessed longer side chains and a greater number of branches with an amorphous crystal structure devoid of a triple helix configuration, and had experienced notable alterations after ultrasonic assisted H 2 O 2 -Vc treatment. Meanwhile, the in vitro antioxidant capacity of FVRPV had significantly increased compared to FVRP, implying ultrasonic assisted H 2 O 2 -Vc technique maybe a effective method to enhance the bioactivity of polysaccharides. In addition, the content of polysaccharide, reducing sugar, and uronic acid in FVRPV was significantly decreased, but antioxidant capacity of fermentation broth was stronger by in vitro human fecal fermentation. The 16S rDNA sequencing data displayed that FVRPV can enrich probiotics and reduce the abundance of pathogenic bacteria through different metabolic pathways mediated by gut microbiota, thereby exerting its potential probiotic effects. The interesting work provides a novel degraded polysaccharide by ultrasonic assisted H 2 O 2 -Vc technique, laying a foundation for developing FVRPV as a new antioxidant and prebiotic.

Despite lignocellulose hindering the extraction of intracellular components, tea residue can serve as an excellent substrate for fungal fermentation owing to their lignocellulose-degrading abilities. Thus, the fermentation efficiencies of Lentinus edodes , Lentinus sajor-caju (Fr.) , Flammulina filiformis , Hericium erinaceus , Pleurotus pulmonarius , and Monascus kaoliang B6 were evaluated using tea residue as a medium. P. pulmonarius and L. sajor-caju (Fr.) exhibited the fastest growth rates, with colony radii of 33.1 and 28.5 mm, respectively. M. kaoliang B6 demonstrated substantial degradation abilities for cellulose, hemicellulose, and lignin, with decolorization radii of 12.2, 0.9, and 8.5 mm, respectively. After a 9-days liquid fermentation, M. kaoliang B6 achieved the highest conversion efficiency at 27.8%, attributed to its high cellulase (191 U∙mL −1 ) and lignin peroxidase (36.9 U∙L −1 ) activities. P. pulmonarius and L. sajor-caju (Fr.) showed lower conversion rates of 8.6% and 3.8%, despite having high hemicellulase activities (67.1 and 70.9 U∙mL −1 ). Fermentation by M. kaoliang B6 resulted in a reduction of protein and total sugar content in the tea residue by 174 and 192 mg g −1 , by which the mycelium's protein and total sugar content increased by 73 and 188 mg g −1 . Co-fermentation of these three strains had little effect on the improvement of conversion efficiency, which might owe to the antagonistic interactions among the strains. Generally, utilizing tea residue for edible fungi fermentation is a sustainable process for bio-waste treatment, enabling efficient nutrient conversion under mild conditions without adding chemicals.

In this work, the physicochemical properties and emulsification performance of water-insoluble dietary-fibers (IDF) from Flammulina velutiper treated with high pressure homogenization were investigated. The homogenization resulted in the breakdown of fibers in the water-insoluble dietary-fibers, and subsequently water-insoluble dietary-fibers with the average width of about 24 nm and height of 4 nm was obtained. The obtained water-insoluble dietary-fibers not only had increased water holding capacity and stability when compared with that of the untreated sample, but also had improved interfacial properties. The water-insoluble dietary-fibers could be irreversibly adsorbed at oil-water interface, exhibiting an outstanding emulsification performance. The temperature, pH and ionic strength had little influence on the stability of the stabilized emulsions. The results would be of importance for the development of a kind of food-grade nanoparticles to perform as outstanding Pickering stabilizers for emulsions, which had great application prospects in food , cosmetics and pharmaceutical fields.

Soybean meal is a class of by-products obtained from the processing of soybean products. Despite its high nutritional value, the presence of glycoside isoflavones limits human use of soybean meal. This study evaluated the effect of solid-state fermentation (SSF) with different edible mushroom mycelia (Pleurotus ostreatus,Hericium erinaceus, andFlammulina velutipes) on the proximate composition, antioxidant properties, and physicochemical properties of fermented soybean meal powder (SP). The results revealed that fermented SP had a higher nutritional value when compared to SP.P. ostreatuswas the most pronounced among the three species. Crude protein content was found to have increased by 9.49%, while the concentration of glutamate and aspartic acid increased by 23.39% and 23.16%, respectively. SSF process significantly increased the total polyphenol content (TPC) and aglycone isoflavone content by 235.9% and 324.12%, respectively, resulting in increased antioxidant activity (evaluated by the DPPH, •OH, ABTS+assays). Microstructural changes in fermented SP and nutrient degradation and utilization were observed. Thus, fermented SP can be used as a raw material with enhanced nutritional properties to develop new functional foods, such as plant-based foods represented by plant meat. It provides a promising approach for increasing the added value of soybean meal.Keywords:soybean meal;solid-state fermentation;edible mushrooms;nutritional value
