Background and objectives Pure wheat bran and wheat germ are the by-products of sieved flour. Pure wheat bran contains a substantial amount of dietary fiber, vitamins B and D, and other nutrients; lipases in the wheat germ induce lipid oxidation and break down vitamins. The present study used heat treatment to stabilize the wheat germ and then compounded it with the extruded pure wheat bran and compared it with the extruded bran. The antioxidant capacity and soluble polyphenols of the compounded wheat bran and extruded wheat bran were subsequently measured, to select a method to improve the antioxidant capacity of wheat bran. Findings The optimized heating temperature of wheat germ was 110°C. The half-maximal inhibitory concentration value of the total antioxidant capacity showed that the compounded wheat bran had a higher antioxidant capacity than the extruded wheat bran. It was hypothesized that the operations of extrusion and heat treatment increased the antioxidant capacity of compounded wheat bran. In addition, after the extrusion treatment, a variety of flavonoid glycosides in the wheat bran was released while the content of various phenolic acid types was decreased. However, the content of the phenolic acid types and flavonoids in the compounded wheat bran was increased. Hence, compounded wheat bran is more suitable for producing functional foods. Conclusion The results of this study revealed that extruded pure wheat bran and heat-treated wheat germ can effectively increase the antioxidant capacity and the content of the phenolic acid types and flavonoids; hence, it is more suitable for producing functional foods. Significance and novelty This study developed a fast and inexpensive detection method that uses a combination of heat and extrude to process compounded wheat bran, which provides the optimal process method for extending the yield and shelf life of wheat bran products.

The effect of wheat bran arabinoxylan (WBAX) with different molecular characteristics on the gelatinization and long-term retrogradation behavior of wheat starch (WS) have been evaluated. WBAXs with M w of 280–754 kDa and Ara/Xyl of 0.45–0.62 were obtained through alkaline extraction with graded ethanol precipitation . WBAXs with larger M w and branching degree could impede gelatinization process of wheat starch by effectively decreasing the water availability for starch gelatinization. The hydrogen-bonding interactions between WS and WBAX could enhance the gel strength of WS-WBAX mixed pastes. WBAXs with lower branching degree could inhibit the long-term retrogradation of starch through hindering the rearrangement of amylopectin and double-helical associations of amylose during long-term storage, due to hydrogen-bonding interaction between WBAX and starch. Low-field nuclear magnetic resonance (LF-NMR) relaxometry analysis confirmed that the addition of WBAXs could improve the water holding properties of retrograded starch gels.

Green surfactants produced from peptides and their derivatives have excellent surface chemistry and application properties. A mild, biocompatible, and rapidly biodegradable green surfactant, potassium N-lauroyl wheat peptide (PLW), was synthesized by an acylation method in the aqueous phase with lauryl chloride and wheat oligopeptide as starting materials. Furthermore, the isoelectric point, equilibrium surface tension, dynamic surface tension, micellar aggregation behavior, foaming, and irritating properties of PLW were studied. Wheat oligopeptides were discovered to have the greatest glutamic acid content, accounting for 30.92% of the overall amino acid composition. The findings revealed that the protonation and ionization behavior of PLW was pH dependent. At pH 8.5, water's surface tension was lowered to 32.1 mN/m −1 . At high concentrations and pH, PLW formed large aggregates in solution, causing the adsorption behavior of PLW molecules to shift from diffusion-controlled adsorption to mixed kinetic adsorption, with PLW exhibiting great surface activity. Furthermore, PLW has good foaming properties and is non-irritating. As a result, PLW is predicted to become widely employed in the field of household chemicals.

Previous studies have shown the great potential of using plasma-activated water (PAW) on improving agriculture seed germination, however, information on the influence of PAW on crop plantlet juice remains scanty. In this research, the effect of PAW generated by atmosphere pressure Ar–O 2 plasma jet for 1–5 min on wheat seed germination, seedling growth and nutritional properties of wheat plantlet juice was investigated. Results revealed that all PAWs could enhance wheat seed germination and seedling growth in 7 days by improving the germination rate, germination index, fresh weight, dry weight and vigour index, and especially that PAW activated for 3 min (PAW-3) showed the best overall performance. In addition, the application of PAWs enhanced the nutritional properties of wheat plantlet juice from those grown for 14 days by improving total soluble solids, protein content, photosynthetic pigments, total phenolic content, antioxidant activity, enzyme activity, free amino acids and minerals content, and the best enhancement was also observed in PAW-3. It was concluded that PAWs would be an effective technique to enhance the growth and nutritional properties of crop sprouts, which could be served as functional foods in many forms.

A new europium metal–organic framework ( Eu-MOF ) was prepared by simple hydrothermal method . The product exhibited intense red fluorescence, long fluorescence lifetime (0.454 ms) and excellent fluorescence stability. The fluorescence titration result showed that Fe 3+ could completely quench the fluorescence of Eu-MOF , while the fluorescence quenching effect of Fe 2+ or bromate was negligible. Considering the strong oxidizing property of bromate, a “turn off” Eu-MOF@Fe 2+ sensor toward bromate was designed by generating Fe 3+ due to the redox reaction . The results showed that the sensor displayed a wide linear range (0–0.2 mM), high sensitivity (LOD = 3.7 × 10 −6 mol/L), good selectivity and resistant to possible interferences in real four sample. Furthermore, the detection mechanism was investigated by PXRD, XPS and UV–Vis methods. More importantly, the Eu-MOF@Fe 2+ sensor was further applied to detect bromate in wheat flour with satisfactory recovery (95.30%−104.38%) and accuracy (RSD < 2.85%). These results suggest that Eu-MOF@Fe 2+ can be used as a potential sensor to detect bromate in food industry.

The application of crops straw and biochar in trace metals remediation from the contaminated environment attracted more and more attention during the past decade. Although there has been some review work on the mechanism of trace metals stabilization by crops straw, the effects and mechanisms of interaction among soil indigenous-microbes and crops-straw for trace metal adsorption and stabilization is still unclear. In this study, the dynamic effects along with potential mechanisms of wheat-straw (WS), wheat-straw biochar (WBC) and biologically modified wheat-straw (BMWS) were conducted to investigate the adsorption, leaching behaviour, chemical fractions and bioavailability of cadmium (Cd). The results showed that the biosorption capacity (q e ) was most elevated in the BMWS treatment (14.42 mg g −1 ) as compared to WBC (6.28 mg g −1 ) and WS (4.20 mg g −1 ). The application of BMWS, WBC and WS at the rate of 3% significantly reduced Cd concentration in leachate to 53, 45 and 21% respectively, as compared to control. The addition of BMWS reduced the exchangeable Cd fraction resulted an increase in organic matter and carbonate bound Cd fraction in the soil. The DTPA extractable Cd was significantly decreased by 31.2 and 28.6% with the application of BMWS and WBC at 3% w/w respectively as compared to control. The research results may provide a novel perceptive for the development of functional materials and strategies for eco-friendly and sustainable trace metal remediation in contaminated soil and water by combination of straw and soil-indigenous microorganisms .

Key message The regulatory action of BXs secreted by wheat on the pathogenicity of FOF causing Fusarium wilt in faba bean were analyzed. DIMBOA and MBOA weakened the pathogenicity of FOF. Abstract A large number of pathogenic bacteria in continuous cropping soil infect faba bean plants, leading to the occurrence of wilt disease, which restricts their production. Faba bean–wheat intercropping is often used to alleviate this disease. This study investigates the effect of benzoxazinoids (BXs) secreted by wheat root on the pathogenicity of Fusarium oxysporum f. sp. Fabae (FOF) and underlying molecular mechanisms. The effects of DIMBOA(2,4-dihydroxy-7-methoxy-1,4-benzoxazine-4-one) and MBOA(6-methoxybenzoxazolin-2-one) on the activity of cell-wall-degrading enzymes in FOF(cellulase, pectinase, amylase, and protease), FOF Toxin (fusaric acid, FA) content were investigated through indoor culture experiments. The effect of BXs on the metabolic level of FOF was analyzed by metabonomics to explore the ecological function of benzoxazines intercropping control of Fusarium wilt in faba bean. The results show that the Exogenous addition of DIMBOA and MBOA decreased the activity of plant-cell-wall-degrading enzymes and fusaric acid content and significantly weakened the pathogenicity of FOF. DIMBOA and MBOA significantly inhibited the pathogenicity of FOF, and metabolome analysis showed that DIMBOA and MBOA reduced the pathogenicity of FOF by down-regulating related pathways such as nucleotide metabolism and linoleic acid metabolism, thus effectively controlling the occurrence of Fusarium wilt in faba bean.

The properties of manufactured nisin-ZrO2/poly (vinyl alcohol)-wheat gluten (ZPWG) films were characterized. The formation of hydrogen bonds among the PVA, WG, and ZrO2 units were detected and caused a decrease in the film crystallinity. Also, the degradation rate was increased with WG content. As expected, the addition of WG and ZrO2 influenced the light transmission, tensile properties, gas permeability and water vapor permeability of the films. Nisin-loaded films presented a low initial burst release of the antimicrobial agent, followed by a gradual release. The initial diffusion of nisin (Mt/M∞<2/3) from the ZPWG film was formulated by the Fickian diffusion equation, showing a linear relationship (R2 > 0.998) between Mt/M∞ and t1/2, and the diffusion coefficient D increased with increasing WG content. Antimicrobial activity testing of nisin-ZPWG films with 40 wt% WG showed excellent inhibitory activity against Staphylococcus aureus, indicating its potential as a new active food packaging material.

Formic acid (FA) is an important material widely used in the chemical industry and in processes involved in energy storage and transformation. In this work, production of FA from wheat straw, an abundant lignocellulosic biomass, in NaVO3–H2SO4 aqueous solution with molecular oxygen (O2) was studied. The conversion showed high efficiencies: 47% (based on carbon, 75.2% based on mass) of FA and 7.3% (based on carbon, 7.6% based on mass) of acetic acid were obtained. The products mainly come from polysaccharides (hemicellulose and cellulose) in wheat straw. Acetic acid is derived from the acetyl groups in (1) the hemicellulose structure or (2) the deep hydrolysis product, levulinic acid. The removal of each lignocellulosic component in wheat straw follows the order: hemicellulose, lignin and cellulose. The catalytic system shows good reusability, and multiple feedings led to a high concentration of FA, which is beneficial to reduce FA–water separation cost.

This study investigated the effects of different wheat flour extraction rate (35–95%) on the protein digestibility of those noodles. And to further elucidate the internal mechanism of above phenomenon, wheat flour with different amounts of wheat bran dietary fiber (WBDF) was produced by adding endogenous WBDF. Results indicated that protein digestibility rose significantly with increasing flour extraction rate, peaking at 91.85% at 80% extraction, before trending downward to 85.71% at 95% extraction. Further, among noodles containing different WBDF content, increasing WBDF content to 6% enhanced the formation of β-sheets, boosting I 755 levels and reducing I 854 /I 830 levels, thus decreasing protein digestibility. As WBDF content rose further, it promoted transition from β-sheets to β-turn, decreasing I 755 and increasing I 854 /I 830 , enhancing protein digestibility slightly. The changes indicated that low level of WBDF induced a more compact protein secondary structure to inhibit protein digestion. Conversely, in noodles with high level of WBDF (>6%), the looser protein secondary structure partially alleviated the inhibitory effect of WBDF on protein digestion, which was caused by part of WBDF penetrating the protein's hydrophobic core. Moreover, the static quenching effect of WBDF on pepsin hydrolysis sites through hydrophobic interaction, especially the tyrosine, was another significant factor inhibiting protein digestion.

Plant lysin motif (LysM) ectodomain receptors interact with pathogen-associated molecular patterns (PAMPs) and have critical functions in plant–microbe interactions. In this study, 65 LysM family genes were identified using the recent version of the reference sequence of bread wheat (Triticum aestivum), in which 23, 16, 20, and 6 members belonged to LysM-containing receptor-like kinases (LYKs), LysM-containing receptor-like proteins (LYPs), extracellular LysM proteins (LysMes), and intracellular nonsecretory LysM proteins (LysMns), respectively. The study found that TaCEBiP, TaLYK5, and TaCERK1 were highly responsive to PAMP elicitors and phytopathogens, with TaCEBiP and TaLYK5 binding directly to chitin. TaCERK1 acted as a coreceptor with TaCEBiP and TaLYK5 at the plasma membrane. Overexpression of TaCEBiP, TaLYK5, and TaCERK1 in Nicotiana benthamiana leaves exhibited enhanced resistance to Sclerotinia sclerotiorum. Subsequently, knocking down TaCEBiP, TaLYK5, and TaCERK1 genes with barley stripe mosaic virus–VIGS compromised the wheat defense response to an avirulent strain of Puccinia striiformis. The study concluded that wheat has two synergistic chitin perception systems for detecting pathogen elicitors, with the activated CERK1 intracellular kinase domain leading to signaling transduction. This research provides valuable insights into the functional roles and regulatory mechanisms of wheat LysM members under biotic stress.
