Most adult parasitoids depend on carbohydrate-rich food as an energy source for longevity, fecundity, and mobility. Thus, providing sugars has been proposed as a technique to maximize the biological control efficacy of parasitoids. However, the sugars provided for parasitoids need to be carefully selected because herbivore hosts might also benefit. Here we explore the effects of 12 naturally occurring sugars on the longevity and fecundity of the rice pest, Chilo suppressalis, and the longevity of its parasitoid, Cotesia chilonis, as well as the effect of sugars on sugar consumption of C. chilonis. Results showed that none of the tested sugars significantly impacted the longevity of C. suppressalis, but fructose, glucose, maltose, and sucrose significantly increased its fecundity. The longevity of C. chilonis was significantly increased when fed fructose, glucose, sucrose, maltose, trehalose, and melezitose. Our data suggest that C. chilonis consumed larger quantities of glucose, fructose, and sucrose followed by maltose, melezitose, and trehalose and the longevity of C. chilonis was positively correlated to sugar consumption. Our data also suggest that the herbivore C. suppressalis and its parasitoid C. chilonis responded differently to trehalose and melezitose. Although additional studies are needed, our data suggest that these sugars could be considered as candidate components for sugar sprays to enhance the activity and efficacy of C. chilonis, but without benefiting its pest host.

Defective coffee beans (DCB) are one of the main reasons for poor coffee quality. In the current research, chemical difference of three common DCB including sour beans (SCB), black beans (BCB), and mold beans (MCB) were clarified using 1 H qNMR method and compared with that of non-defective beans (NDCB). The results indicated that DCB has lower sugar and lipid content compared to NDCB, yet it boasts a higher acetate concentration. The 1 H NMR from water-soluble content was shown to be more effective than that of oil fraction for qualitative of DCB blends, regardless of whether partial least squares discriminant analysis (PLS-DA) or machine learning (ML) algorithms were used. Support vector machine (SVM) was proved to be excellent for distinguishing DCB blends. Finally, a partial least squares regression (PLS) model was built for quantitative analysis of DCB blends. In summary, current research will not only help to reveal the material basis of DCB and their impact on coffee flavor, but also provide feasible strategies for the identification of DCB.

Biological pretreatment is a safe and environmentally friendly method for disrupting recalcitrant lignocellulose structures. Expansin and expansin-like proteins are used to open up the cellulose structure and display significant synergism when mixed with cellulases that catalyze the breakdown of (hemi)cellulose into sugars. However, the adsorption behavior of expansin in the presence of sugar products is yet unknown. In this work, we monitored the effects of various sugars on the real-time adsorption of Bacillus subtilis expansin (BsEXLX1) onto cellulose films using a quartz crystal microbalance with dissipation. Cellobiose and xylose at low concentrations enhanced BsEXLX1 adsorption, whereas they disrupted adsorption at higher concentrations. Arabinose and mannose continuously inhibited expansin adsorption with increasing concentration. No obvious influence of glucose and galactose on BsEXLX1 adsorption was found. Contact angle measurements and atomic force microscopy of cellulose upon BsEXLX1 adsorption in the presence of sugars showed that both hydrophilicity and roughness increased with BsEXLX1 treatment. These results give us the ability to modulate and control expansin adsorption and provide insights into effective expansin use during enzymatic hydrolysis of lignocellulose in biorefineries.

Sugars are among the main compounds in bio-oil produced by biomass pyrolysis. However, they can easily form coke, resulting in fast deactivation of the catalyst and severe blockage of the reactor during catalytic upgrading of bio-oil. Molecular distillation may be performed to retain sugars and pyrolytic lignin in the heavy fraction and thus to provide a primary stage for the subsequent sugar separation and utilization. A new method involving extraction, heat treatment, and column chromatography was introduced to separate further the aqueous phase obtained from the bio-oil heavy fraction by methanol–water extraction. Thus, monophenols and sugars were coextracted through these combined separation technologies. A fraction rich in monophenols was obtained by solvent extraction. Other impurities were further removed by heat treatment and column chromatography. An alcohol sedimentation method further separated the combined sugar-rich fraction into an ethanol-soluble fraction (SF-1) and an ethanol-insoluble fraction (SF-2). Gas chromatography–mass spectrometry, Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, and high-performance liquid chromatography were performed to characterize sugars in the obtained fractions. SF-1 mainly contained monosaccharides such as levoglucosan, glucose, and xylose, whereas SF-2 still had a small amount of cellobiose besides monosaccharides. The ultimate recovery rates for several identified monosaccharides were in the range of 75–86 wt %.

A single boronic acid-based fluorescent probe (compound CSP) for saccharides was designed and synthesized. The probe, with an α , β -unsaturated ketone conjugated into the coumarin fluorophore, was synthesized by 4 steps from the commercial material 4-diethylamino salicylaldehyde. The electron push-pull effect is enhanced with the N , N -diethyl amino as the electron donor and the carbonyl as the electron acceptor. Both the absorption (463 nm) and emission (616 nm) maxima of CSP are in the visible wavelength region with a Stokes shift of about 150 nm, which ensures CSP a potential probe for biological application. Under near physiological conditions, significant fluorescence enhancement of CSP was observed upon the addition of some saccharides, namely, D -sorbitol, D -fructose, D -glucose, D -mannose and D -galactose. The probe showed relatively high sensitivity towards D -fructose and D -sorbitol, and their detection limits were 0.05 mmol/L and 0.1 mmol/L, respectively.

A method utilizing high-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD) has been developed and validated for the simultaneous determination of raffinose, glucose, sucrose, and stachyose in waste liquid from cottonseed processing and in byproducts including cottonseed meal. The separation was performed using a carbohydrate ES column (250 × 4.6 mm, 5 μm) and isocratic elution with acetonitrile and water (70:30, v/v). The temperature of the column oven was maintained at 35 °C. The drift tube temperature for evaporative light scattering detection (ELSD) was operated 40 °C, while the nitrogen flow was set to 1.5 L·min−1. The saccharides were separated by HPLC-ELSD within 20 min. The coefficients of determination (R2 = 0.9986–0.9999) indicate that there was a linear relationship between saccharides and the response. The limits of detection were 0.004–0.023 mg·mL−1 and the quantification range was from 0.013 to 0.080 mg·mL−1. The intraday and interday precision were from 0.05 to 0.55% and 0.20 to 0.58%, respectively. The recovery was from 102.75 ± 2.03% to 106.76 ± 2.09% and the relative standard deviations were 1.87 to 1.98%. The method exhibited good stability in determining four saccharides in cottonseed processing waste liquid and the resultant byproduct cottonseed meal. This method exhibits high separation efficiency and sensitivity, excellent precision, and simplicity, which allows determination of the high value-added product, raffinose, in cottonseed processing waste liquid and meal.

Levulinate is one of the high added-value biomass-derived chemicals that is primarily produced from hexoses in cellulose and hemicellulose. Producing levulinate from pentoses in hemicellulose that is extensively distributed in biomass is still highly challenging. In this study, biomass materials and carbohydrates (including cellulose, xylan, glucose, fructose, and xylose) were collaboratively converted into levulinates efficiently over various zeolites with ethanol/dimethoxymethane as cosolvents. The key process for converting pentoses into levulinates is the synthesis of intermediates (furfural) into alkoxy methyl furfural via electrophilic substitution or their conversion into furfuryl alcohol via in situ hydrogenation. The substitution was achieved by the synergic effect between bifunctional catalysts and cosolvents, which promotes conversion of furfural into alkoxy methyl furfural via the electrophilic addition of alkoxy methyl radicals. Hydrogenation of furfural into furfuryl alcohol was impelled by the cooperative process between in situ generated H-donor from alcohol solvents and zeolite catalysts. Moreover, a favorable yield of 21.05 mol % of levulinates was achieved by simultaneous and collaborative conversion of cellulose and hemicellulose with the one-pot process using ethanol/dimethoxymethane as a cosolvent and the zeolite with B and L acid sites as a catalyst.

Gas–solid phase reactions between ozone (O3) and three representative solids (alcohols, phenols, and saccharides) were investigated through a heterogeneous chemiluminescence (CL) strategy. When interactions between these two species occurred at the surface of the solid powder, an obvious CL effect was obtained. This performance could be attributed to the evolution of a ROOOH intermediate, which subsequently released emissive 1O2 species. This is the first report analyzing the gas–solid phase CL performance of O3 with alcohols, phenols, and saccharides. It is believed that this strategy can be extended to applications in other gas–solid phase CL analyses utilizing the O3 system. This has also created a novel area of gas–solid CL performance; thus, relevant processes and mechanisms can be deduced and identified.

Graphical Biomass valorization with bioderived catalysts ! Renewable and sustainable betaine-based catalysts (BX) are prepared for the production of 5-hydroxymethylfurfural (HMF) from various carbohydrates and biomass in satisfactory yields. The introduction of choline chloride (ChCl) significantly improves the HMF yield, and the catalytic activity of ChCl-derived choline-O-sulfate (ChOS) is also demonstrated. This work introduces a promising approach for the use of biomass-derived catalysts for effective valorization of biomass. Renewable and sustainable betaine-based catalysts (BX) derived from the betaine sugar industry or ChCl were developed for the production of 5-hydroxymethylfurfural (HMF) from various carbohydrates. The HMF yields in the BX-based media reached up to 88 %, 66 %, 37 % and 53 %, for the conversion of fructose, glucose, cellulose, and lignocellulosic biomass, respectively. In addition, choline-O-sulfate was synthesized and demonstrated to be an efficient catalyst for the conversion of fructose to HMF. From the perspective of green and sustainable chemistry, this work demonstrates benefits not only in the preparation of sustainable catalysts but also the green production of HMF from biomass.

Graphical Two catalytic transfer hydrogenation (CTH) routes of alditol production using biomass-derived sugars as the hydrogen donors in the aqueous solution, achieving a considerable yield of alditol and high hydrogen utilization ratio. The utilization of biomass-derived sugars as the emerging hydrogen donor in catalytic transfer hydrogenation (CTH) reactions has received great attention in recent years. In this work, we proposed two CTH routes of alditol production in the aqueous solution, i. e. self-disproportionation of sugar and cross CTH of different sugars. Both could realize the process of sugar towards alditol. Taking advantage of the differences in hydrogenation and dehydrogenation capabilities of different sugars, a high C4 alditol yield of 85.9 % was surprisingly obtained via cross CTH route using glucose as the hydrogen donor, which is much better than that obtained when using traditional hydrogen donor isopropanol. The CTH reactions using sugars as the hydrogen donor can not only reduce the utilization of fossil energy, but also provide a new pathway for the production of alditols.

The study investigates the gelation kinetics of gelatin in the presence of various saccharides, including common sugars (sucrose, fructose, & glucose), rare sugars (ribose, allulose, isomaltulose, & trehalose), and prebiotic trisaccharides (raffinose and 2′-fucosyllactose). Gelation kinetics, including the initial sol-gel transition and subsequent aging, was monitored using a rheometer, while gel properties were assessed through texture analysis, differential scanning calorimetry, and centrifugation. The effects of these cosolutes on sol-gel transition varied depending on their molecular weight and stereochemistry, but they generally hindered gel network aging due to increased bulk viscosity. Ribose and allulose inhibited gelatin sol-gel transition, resulting in weak gel strength at all concentrations. Arabinose and raffinose crystallized rapidly at high concentrations, damaging gel structures. At low to medium concentrations (10–30 %), di- and trisaccharides accelerated gelation, but at higher levels, increased bulk viscosity impeded gel percolation, reducing gel strength. In terms of gel-stabilizing forces, the addition of sucrose promoted electrostatic interactions but weakened hydrogen bonding within gel network. This work emphasizes the need to account for gelatin-to-water ratio when evaluating cosolute effects. The findings provide valuable insights for sugar reduction and functionalization for gelled foods.

Saccharides are the dominant factor shaping the texture of freeze-dried products. This study investigated the impact of various molecular-weight saccharides at different concentrations on the physical properties and intermolecular interactions of pectin-CMC cryogels by experiment and molecular dynamic (MD) simulations. Results showed that the increased shrinkage of cryogels and enhanced molecular interactions between saccharides and pectin-CMC were mechanisms that enhanced the hardness of cryogels. Notably, the cryogel with fructose exhibited significantly higher hardness compared to cryogels with other saccharides. The cryogel containing 16 % fructose had the lowest glass transition temperature ( T g ), leading to the highest shrinkage (70 %). Moreover, the MD results revealed that fructose had the highest intermolecular interaction energy (coulombic short range) with pectin-CMC (−5316.78 kJ/mol). This study revealed that the intermolecular interactions between the added saccharide and the pectin-CMC, in addition to the density of the cryogel, are critical determinants of the hardness and crispness of cryogels.
