In this study, Hakka yellow wine lees carbon dots (HYWL-CDs) with an average diameter of 1.75 nm are synthesized from Hakka yellow wine lees (HYWL) via a one-pot hydrothermal method. Results of X-ray photoelectron spectroscopy and FTIR reveal the presence of C=C and –OH in the HYWL-CDs. Additionally, the HYWL-CDs present excitation-wavelength dependence, with maximum excitation and emission wavelengths of 360 and 440 nm, respectively. The fluorescence of the HYWL-CDs can be quenched by Fe 3+ . The Fe 3+ concentration is correlated linearly with the quenching rate over a linear range of 0.6–1.1 mg/mL, and the limit of detection is 0.18 μg/mL. And phenols have been shown to be present in HYWL-CDs, and the color reaction between phenols and FeCl 3 is most likely the mechanism by which FeCl 3 causes fluorescence burst in HYWL-CDs. Moreover, the HYWL-CDs demonstrate significant potential for detecting NaFeEDTA in iron-fortified soy sauces, the linear-fit equation was y = 185.38x + 1024.6 (R 2 = 0.9995) The HYWL-CDs are loaded onto paper strips, iron-fortified straw mushroom dark soy sauce showed noticeable color changes, which allows one to differentiate normal soy sauce from iron-fortified soy sauce more conveniently and provides a new perspective for the high-value utilization of yellow wine lees.

Modern agriculture has caused extensive soil pesticide contamination, which is a global concern. This study explored the potential of bamboo charcoal (BC) to alleviate quinclorac-induced stress in tobacco plants. A pot experiment was conducted to investigate the effects of BC and vinasse fertilizer (VF) on the growth and physiological parameters of tobacco plants subjected to quinclorac stress. At 30, 60, and 90 d after transplantation, BC and VF exhibited pronounced restorative effects on quinclorac-stressed tobacco plants. The treatments improved plant height, leaf length, and leaf width, and enhanced leaf quality and various biochemical indicators. Treatment with 500 g VF + 4% BC resulted in the lowest residual quinclorac levels in both the soil and leaves. Treatment with 500 g VF + 2% BC resulted in the most significant recovery of agronomic traits, whereas 500 g VF + 0.5% BC was the most effective in enhancing leaf quality. However, the effectiveness of BC decreased with time following application, and furthermore, quinclorac may be released from the BC. In conclusion, BC shows promise in alleviating the adverse effects of quinclorac stress in tobacco plants.

Resource utilization of distiller's grains (DGs) is crucial for realizing sustainable development of Baijiu industry. In the prevent investigation, a low-cost activated biochar (DGABC) suitable for removing turbidity from low-alcohol Baijiu was prepared by the controlled pyrolysis of DGs, followed by steam activation. The as-prepared biochar featured a large specific surface area (320–480 m 2 /g) and pore volume (0.45–0.47 cm 3 /g). Importantly, the DGABC possessed remarkable exterior hydrophily and interior lipophilicity, which guaranteed its good dispersion in alcohol-water system as well as an efficient adsorption to the components with long lipophilic chain. As a result, the DGABC could efficiently remove the turbidity in low-alcohol Baijiu, which was mainly derived from the long lipophilic chain components, such as ethyl palmitate. Meanwhile, most of the flavor esters that had a shorter lipophilic chain and lower hydrophobicity were well kept in the low-alcohol Baijiu. Therefore, this work provided a promising strategy for DGs recycling in Baijiu industry.

Yellow wine lees (YWL) are the main byproduct in the yellow wine brewing and can be used as animal feed. The deficiencies in fiber digestibility and amino acid equilibrium of YWL limited its utility value in animal feeding. The nutritional profile of YWL could be moderated after fermentation treatment. We fermented YWL with Candida utilis KF01 and Bacillus subtilis KF02, whose genomes were sequenced. We set three groups in the animal test with 15 Holstein cows : control, YWL, and fermented yellow wine lees (FYWL) group. 206 and 5 amino acid metabolism-related KEGG pathways, as well as 5257 (639 GO and 4618 eggNOG annotations) and 1579 (372 GO and 1207 eggNOG annotations) amino acid metabolism-related gene annotations were found in C. utilis KF01 and B. subtilis KF02. The collected milk samples were analyzed for composition. The contents of mono-unsaturated fatty acid (MUFA, 36.90% relative content), poly-unsaturated fatty acid (PUFA, 5.63% relative content), and essential amino acid (EAA, 2.01%) in the FYWL group milk were significantly (P < 0.05) higher. The content of flavor substances in the FYWL group (146.33 ng/mL) was the highest, followed by the control (89.19 ng/mL) and the YWL group (41.36 ng/mL). The principal component analysis (PCA) result presented the intra-group variations in flavor substances and differences in single substance among all groups. Feeding FYWL had significant effects (P < 0.05) in the Holstein cows on the milk composition.

Waste baijiu distillers’ grains (BDGs) are one kind of low-value-added biomass originated from Chinese baijiu industry. Considering the large quantity and abundance in carbon element, conversion of waste BDGs to biochar as functional material is of great potential for the sustainable development of baijiu industry. In this study, with the assistance of potassium acetate as activation agent, waste BDGs were converted to highly porous biochar materials through a pyrolysis procedure. Taking the advantages of large specific surface area, well-developed micro- and mesopores, partially graphitized carbon with thin layer structure and abundant surface functional groups, the waste BDGs-derived biochar performed well for the removal of typical organophosphate esters (OPEs) in water, e.g., a maximum adsorption capacity for triphenyl phosphate (TPhP) reached 752.95 mg g −1 over biochar sample of BC 1:3–900 . Although the adsorption equilibrium needed up to 10 h to reach, over 50 % effective adsorption was completed in the first 30 min. The adsorption behavior of TPhP on biochar was identified as an exothermic and mono-layer adsorption process, including both fast surface adsorption and relatively slow intra-particle diffusion steps. Solution pH did not affect TPhP adsorption much, but environmental temperature showed great influence on TPhP adsorption capacity. The developed biochar of BC 1:3–900 was still effective for TPhP removal from natural water bodies. Further studies indicated that π-π electron-donor-acceptor (EDA) interaction, hydrogen bonding, σ bonding as well as pore filling effect were the main adsorption mechanisms, contributing to the good adsorption performance of biochar. Besides of aromatic OPEs of TPhP and tricresyl phosphate (TCP), the optimized biochar material was also efficient in removing alkyl and halogenated OPEs, i.e., tributyl phosphate (TBP) and tris(2-chloroethyl) phosphate (TCEP). The facile preparation procedure of biochar material and their good adsorption performance bring a possible alternative for the treatment of OPEs-containing water/wastewater.

Thin stillage is the distillery stillage from distilled alcoholic beverage, which has great economic potential. In this study, a novel polysaccharide from the thin stillage of distilled alcoholic beverage (CRWP1) was purified with a molecular weight of 8554 Da. CRWP1 was mainly composed of glucose, galactose , mannose , and glucuronic acid at approximate percentages of 91.56, 2.13, 1.61 and 1.84, respectively. The structural chain of CRWP1 consisted of (1→4)-linked -Glcp, (1→)-linked-Glcp, (1→3,6)-linked-Manp, (1→6)-linked-Galp, (1→6)-linked-Glcp and contained with α and β glycosidic bonds by fourier transform infrared spectroscopy (FTIR), methylation and nuclear magnetic resonance (NMR) analysis. Following 48 h of fecal fermentation in a bionic gastrointestinal reactor, CRWP1 could promote the relative abundance of Bacteroides , Bifidobacterium , and Collinsella at the genus level, as well as the production of short-chain fatty acids (SCFAs). Furthermore, CRWP1 fermentation increased production of organic acids (especially butyric and oleic acids) and polyols (such as 1,3-propanediol). This is the first report on the prebiotic potential of CRWP1 and it provides a foundation for the potential application in economical food industry.

Porous activated carbons (AC-AN and AC-AO) for toluene adsorption were prepared starting from brewer’s grain biomass pretreated with microorganisms (Aspergillus nigervan Tieghem for AC-AN andAspergillus oryzaeRIB40 for AC-AO). The structures and chemical properties of the three activated carbon materials (AC-AN, AC-AO, and AC that was not pretreated with microorganisms) were characterized by N2adsorption–desorption isotherms, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The adsorption behavior of the three activated carbons for toluene was studied and correlated with the physical and chemical properties of these materials. The results suggested that the activated carbons prepared by microbial pretreatment had a rougher morphology, higher specific surface area, richer pore structure, fewer oxygen-containing functional groups on the surface, and better adsorption performance for toluene (increased by 31.5% and 18.3% with AC-AN and AC-AO, respectively) compared with the untreated activated carbon (AC). The Thomas model was used to fit the toluene adsorption data, indicating that the rich pore structure accelerated the kinetic process of toluene adsorption. Therefore, appropriate microbial pretreatment of the feedstock that is used to prepare activated carbon can effectively improve its adsorption capacity towards toluene.

Prolamins, proteins derived from plants, have extensive applications in pharmaceutics and food science. Jiuzao is a byproduct of the Baijiu brewing industry, and is a great source of prolamin. Despite its importance, knowledge regarding the extraction techniques and the properties of prolamin derived from Baijiu Jiuzao (PBJ) remains limited. Reverse micelles (RMs) extraction offers an efficient and cost-effective method for purifying proteins. In the present study, prolamin was extracted from Baijiu Jiuzao using RMs extraction and subsequently characterized in terms of its secondary structure, morphology, and particle size distribution. Our findings indicate that the purified prolamin extracted using further RMs extraction possessed higher α-helix content (+13.25%), forming a large-scale protein network, and narrower particle size distributions compared to the crude prolamin obtained by NaOH-ethanol method. This research suggests that RMs extraction has potential applications in extracting prolamin from brewing industry byproducts, offering an environmentally friendly approach to Baijiu Jiuzao recycling.

Xanthophylls extracted from corn distillers’ dry grain were successfully applied to dye wool fabrics. As a readily available and cost-effective grain processing byproduct, corn distillers’ dry grain contains appreciable amounts of isolable xanthophyll colourants, which can potentially be used in textile coloration. However, the application of xanthophylls as textile colourants has been limited, possibly owing to their hydrophobic nature and lack of stability at higher temperatures. In the present work, dyeing of wool fabrics with xanthophyll dyes was performed in the presence of a solubilising agent (diglyme) and an antioxidant (butylated hydroxytoluene). Dyeing conditions were modelled and optimised by the one-factor-at-a-time method and response surface methodology. Depth of shade of the wool fabrics dyed with 0.33 g l −1 of xanthophylls could be as high as 10.9 ± 0.5, while the colour fastness to laundering and crocking was better than grade 4. The prominent effect of butylated hydroxytoluene on depth of shade ( K / S ) was further studied using functionally and structurally related model compounds. The K / S -enhancing ability of butylated hydroxytoluene was found to be a synergistic result of its antioxidising and complexing abilities. Lab-extracted xanthophylls of various purities were applied to wool fabrics using the optimised dyeing and aftertreatment conditions. Depth of shade but not colour fastness was significantly affected by the impurities in xanthophylls extracted from corn distillers’ dry grain. The strategy developed by this work not only extends the scope of xanthophyll application into textile coloration but also could be used for other hydrophobic and unstable natural colourants.

Wine lees is a low value biomass resource rich in cellulose, with great potential for producing organic fertilizers and chemicals. However, the high acidity of wine lees limits the catalytic efficiency of the conversion tool endoglucanase. Here, we expressed endoglucanase tCel5A from Trichoderma reesei in Pichia pastoris, and the combination of promoter AOX1 and signal peptide SUC2 resulted in a highly active expression of 4632.81 U/mg. Subsequently, the catalytic center design and surface charge modification strategy resulted in mutants T88H/W255H and S45D/T55D/T59D exhibiting catalytic activity twice and three times higher than WT at pH 3.0, respectively. Finally, when the solid–liquid ratio was 1:15 (w/v), the degradation rate of wine lees was nearly double that of WT. The degradation products contained a variety of industrial and pharmaceutical raw components, including the antioxidant and anticonvulsant isopiperolein B. This study accelerates the green and sustainable management of wine lees.

To enable a wider utilization of co–products from beer processing and minimize the negative effect of added grain on bread quality, flavor, and other attributes, brewer’s spent grains (BSG) are processed through microwave pretreatment, and then the microwave–treated BSG (MW–BSG) is added to bread. So far, there has been no investigation on the effect of microwave–pretreated BSG on bread quality and flavor. In this study, we examined the effects of diverse microwave treatment variables on the physicochemical structure of BSG and explored the consequences of MW–BSG on the quality and flavor of bread. The results showed that soluble dietary fiber and water–soluble protein levels in MW–BSG increased significantly (144.88% and 23.35%) at a 540 W microwave power, 3 min processing time, and 1:5 material–liquid ratio of BSG to water. The proper addition of MW–BSG positively affected the bread texture properties and color, but excessive amounts led to an irregular size and distribution of the bread crumbs. The result of electronic nose and HS–SPME–GC–MS analyses showed that the addition of MW–BSG modified the odor profile of the bread. A sensory evaluation showed mean scores ranging from 6.81 to 4.41 for bread containing 0–10% MW–BSG. Consumers found a maximum level of 6% MW–BSG acceptable. This study endeavors to decrease environmental contamination caused by brewing waste by broadening the methods by which beer co–products can be utilized through an innovative approach.

Aflatoxin B1 (AFB1) is a toxic compound naturally produced by the generaAspergillus. Distillers’ grains can be used as animal feed since they have high content of crude protein and other nutrients. However, they are easily contaminated by mycotoxins, and currently there are no rapid detection methods for AFB1 in distillers’ grains. In this study, a lateral flow immunoassay (LFIA) based on red fluorescent microsphere (FM), is developed for quantitative detection of AFB1 in distillers’ grains. The whole test can be completed within 15 min, with the cut-off value being 25.0 μg/kg, and the quantitative limit of detection (qLOD) being 3.4 μg/kg. This method represents satisfactory recoveries of 95.2–113.0%, and the coefficients of variation (CVs) are less than 7.0%. Furthermore, this technique is successfully used to analyze AFB1 in real samples, and the results indicates good consistency with that of high-performance liquid chromatography (HPLC). The correlation coefficient is found to be greater than 0.99. The proposed test strip facilitates on-site, cost-effective, and sensitive monitoring of AFB1 in distillers’ grains.Keywords:aflatoxin B1;distillers’ grains;fluorescent microspheres;lateral flow immunoassay
