The widespread application of bisphenols (BPs) makes them ubiquitous in the natural environment and poses many potential risks. In this study, we examined the effects of perinatal exposure to BPA and its 3 alternatives (BPS, BPF, and BPAF) on lipid and glucose homeostasis in female mice adolescent offspring . Specifically, BPA exposure promoted the expression of hepatic lipid synthesis and fatty acid accumulation genes, resulting in a significant increase in 2 free fatty acids contents. BPS exposure caused an increase in 6 free fatty acids and triglyceride contents through promoting the expression of fatty acid synthesis, triglyceride synthesis and fatty acid accumulation genes and inhibiting the expression of fatty acid β-oxidation genes. Interestingly, BPAF exposure showed completely opposite effects on hepatic lipid metabolism compared to BPS exposure. 9 free fatty acids and triglycerides contents in the liver were significantly reduced. In particular, BPF exposure caused decreases in 2 free fatty acids contents, but no significant changes were found in the genes for lipid metabolism. In addition, unlike BPA and BPF exposure, BPS and BPAF exposure also resulted in significant increases in glucose and glycogen contents in the liver by activation of Fxr-Sh p pathway and glycolysis, and inhibition of gluconeogenesis. The results showed that compared to BPA and BPF exposure, BPS and BPAF exposure significantly regulated the expression of genes related to glucose and lipid metabolism and severely interfered with hepatic lipid and glucose homeostasis. This suggested that we should thoroughly evaluate the potential health risks of BPA and its alternatives.

Lotus ( Nelumbo nucifera, G.) is a perennial aquatic plant, which is utilized for a variety of therapeutic and food applications. Muffins are a kind of baking product that is typically consumed for breakfast or as a snack. Currently, many baked goods in the market use fat replacers to lower the overall fat content, while conserving consumer approval. The study's objectives were to produce low-fat muffins and to characterize the types of quality changes that occurred in the muffins. Lotus rhizome was sliced, dried and converted into powder, which used as fat substitute in muffins, at 0, 5, 10, 15 and 20% replacement levels, with names as M 0 , M 1 , M 2 , M 3 and M 4 , respectively. Composite flours having these proportions of lotus Rhizome Powder (LRP) were analyzed for proximate and rheological parameters. Increasing levels of LRP caused increased water absorption and dough development time of the composite flours. Proximate analyses of muffins showed highest value of moisture (25.05%), ash (2.43%), fiber (0.99%), protein (11.89%) and NFE (58.45%) in M 4 . Whereas, fat content and energy value were significantly reduced in M 4 , as highest fat was found to be in M 0 (36.65%) and highest calories in M 0 (576.5 kcal), which were significantly reduced to 26.24% and 514.5 kcal, respectively in M 4 . High yeast and mold count was of M 0 at first day as 98 CFU/g, which was increased to 129 CFU/g at day 7, whereas M 4 presented this count to be 44 CFU/g at day one, which was increased to 70.33 CFU/g at day 7. Texture analysis showed softest texture of M 4 as firmness value was 1887 g, which was significantly high in M 0 as 2285 g. The research revealed that M 3 best performed out of all treatments as 15% replacement of fat with LRP significantly improved the rheological properties of the flour, ash and fiber content were high, whereas fat contents were significantly low in these muffins. Textural and sensory analysis also supported the M 3 due to softer texture and significantly high color, appearance, flavor, and overall acceptability scores. From the results of this study, it could be concluded that a 15% replacement of shortenings with LRP could be considered as optimum for developing good quality baked muffins. Graphical

In the plywood industry, formaldehyde-based adhesives are commonly used, but the health risks associated with them are a significant concern. As a result, there has been a growing emphasis on developing formaldehyde-free alternatives. This study presents an eco-friendly adhesive formulated from vinyl acetate-ethylene (VAE) copolymer emulsion and polyvinyl alcohol (PVA). The synthesis conditions, curing behavior, synthesis mechanisms and curing mechanisms were further investigated. The optimal preparation conditions were as follows: VAE emulsion and 4 % PVA1788 were synthesized at 90 °C for 2 h, and the solid content was adjusted to 50 % by adding distilled water. Subsequently, 5 % pMDI was incorporated. The wet shear strength of the resulting adhesive, which is 0.93 MPa, met the requirements of the Chinese national standard GB/T 9846-2015 (≥0.7 MPa) for Class II plywood. The curing behavior of the VAE-PVA adhesive was investigated by measuring the insoluble mass proportion and thermal analysis. The results showed that when the adhesive was heated at 130 °C for 10 min, the insoluble mass proportion reached 81.16 %, and an endothermic reaction occurred at approximately 100 °C. To investigate the synthesis mechanism of VAE-PVA adhesive, FT-IR analysis revealed that esterification occurred between the VAE emulsion and the hydroxyl groups in PVA. Additionally, FT-IR analysis, XPS analysis, and Py-GC/MS analysis were used to explore the curing mechanism of the VAE-PVA adhesive. The results indicated that during the curing process, pMDI polymerized with the vinyl groups in the VAE emulsion and the hydroxyl groups in PVA, forming a three-dimensional network of cured polymer.

Rapeseed oil has a similar oleic acid/linoleic acid ratio to human milk fat (HMF). However, it can hardly be used for human milk fat substitute (HMFS) synthesis due to high erucic acid content. In this study, Candida cylindracea lipase (CCL) was found to strongly discriminate against erucic acid. Free fatty acids containing low erucic acid and high oleic acid and linoleic acid were prepared from rapeseed oil hydrolysis catalyzed by CCL. The erucic acid content was only 1.58% (initial 8.70%), when the degree of hydrolysis reached 79.58%. The free fatty acids were used as acyl-donors in the acidolysis catalyzed by Novozym 40086. Considering acyl incorporation and migration, the optimum conditions were 1:8 (tripalmitin to acyl-donors), 40 °C and 2 h. The erucic acid content dropped to 0.97% in the HMFS. According to the Q-TOF-MS analysis, the HMFS was rich in 1,3-dioleoyl-2-palmitoyl-glycerol (18.20%) and 1-oleoyl-2-palmitoyl-3-linoleoyl-glycerol (17.96%), which was similar to HMF.

Konjac glucomannan (KGM) undergoes deacetylation in alkaline conditions, while κ-carrageenan (CRG) is sensitive to potassium ions. This study examines the influence of K 2 CO 3 on the mechanical properties of KGM/CRG-based camellia oil Pickering emulsion gels. Texture analysis and rheological testing revealed that the addition of K 2 CO 3 significantly enhanced the mechanical properties of emulsion gels. Texture parameters, such as the hardness, gumminess, and chewiness of the gel, were closer to those of pork back fat when the K 2 CO 3 concentration was 0.2 M. The addition of K 2 CO 3 enhance the intermolecular crosslinking within the gel and formed a more uniform and dense gel network, promoting gelation and structural stability, which were confirmed by Fourier transform infrared spectroscopy, X-ray diffraction, and microstructural analysis. Besides, low-field nuclear magnetic resonance and thermogravimetric analyses indicated that the addition of K 2 CO 3 reduced the water mobility of the gel and improved its thermal stability. Physicochemical and color analysis results showed that the energy value of the camellia oil Pickering emulsion gel was only 15.9 % that of pork back fat, and its appearance was closer to that of pork back fat than hydrogels. This study provides technical support for the use of KGM/CRG-based camellia oil Pickering emulsion gels as fat analogs.

The frequent detection of 6:2 chlorinated polyfluorinated ether sulfonate (F-53B) in various environments has raised concerns owing to its comparable or even higher environmental persistence and toxicity than perfluorooctane sulfonate (PFOS). This study investigated the plasma degradation of F-53B for the first time using a water film plasma discharge system. The results revealed that F-53B demonstrated a higher rate constant but similar defluorination compared to PFOS, which could be ascribed to the introduction of the chlorine atom . Successful elimination (94.8–100 %) was attained at F-53B initial concentrations between 0.5 and 10 mg/L, with energy yields varying from 15.1 to 84.5 mg/kWh. The mechanistic exploration suggested that the decomposition of F-53B mainly occurred at the gas-liquid interface, where it directly reacted with reactive species generated by gas discharge . F-53B degradation pathways involving dechlorination , desulfonation , carboxylation , C-O bond cleavage , and stepwise CF 2 elimination were proposed based on the identified byproducts and theoretical calculations. Furthermore, the demonstrated effectiveness in removing F-53B in various coexisting ions and water matrices highlighted the robust anti-interference ability of the treatment process. These findings provide mechanistic insights into the plasma degradation of F-53B, showcasing the potential of plasma processes for eliminating PFAS alternatives in water.

Producing heat-stable, bloom-resistant chocolate is a significant challenge faced by the food industry. This study prepared oleogels using palm oil as a base oil and monoglyceride stearate as an oleogelator, which were introduced into partially substituted cocoa butter (CB) (30% w/w) to manufacture heat-stable, bloom-resistant chocolate. In addition, various healthy sweeteners (maltitol (M), tagatose (T), and palm sap sugar (PS)) were used (corresponding chocolate noted as Choc M100, Choc T5 & T10, and Choc PS25 & PS50, respectively) at different substitution ratios to sucrose . The melting properties and fat blooming behavior were characterized to optimize the suitable recipe for the chocolate. According to the results, Choc PS50 exhibited the required crystal form (β-form), improved the shape retention index (SRI), displayed a higher melting enthalpy ( Δ H m ) and ideal fat bloom-resistance, while showing fewer superficial crystals during temperature cycling (16 h at 20 °C and 8 h at 32 °C for 40 d). Nevertheless, the formulated chocolates exhibited significantly lower hardness due to the reduced CB content. This study provided an approach to manufacturing heat-stable, bloom-resistant chocolate.

An innovative and facile method was developed to fabricate oleogels from biopolymers. Gelatin nanofibers were prepared by electrospinning and crosslinked by genipin, and through the one-step homogenization of nanofiber membranes and camellia oil, electrospun fiber-based oleogels (EFO) were obtained. Genipin crosslinking enhanced the fiber diameter from 138.66 to 311.92 nm, providing different nanofiber modules for oleogel preparation. The network structure in EFO was confirmed by microstructure examination, and fiber content and crosslinking influenced the protein conformation and thermal stabilities. Adding nanofiber in EFO effectively increased the apparent viscosity and oil binding capacity (up to 79.32%) while crosslinking decreased the values to some extent. Nevertheless, the highly crosslinked samples with a high fiber content had the best thixotropic recovery (83.24%). Crosslinking also contributed to a steadier free fatty acid release performances with a final release amount of 50.31%. Furthermore, EFO was successfully utilized to replace commercial solid fats in making cookies with considerable performances. Results indicated that EFO could be conveniently prepared by the new method, and samples were promising as fat substitutes in healthy diets. In addition, due to the simplicity and universality of this method, more biopolymers and modification strategies could be accessible in electrospun nanofiber dispersing oleogel systems.

Phytosterol-based oleogels have been engineered in edible oils for potential applications as sustainable replacements for petrolatum. Oleogels have emerged with a crystal network structure with oil molecules trapped inside. In addition, the viscosity of highly thixotropic oleogels could be tuned by manipulating the concentration of phytosterols and monoglycerides, and the type of surface-active small molecules and bulk vegetable oils. Furthermore, viscous soft matter could also be tunably made with 8–20% oleogelators in olive oil with favourable water vapour occlusive and wettability properties, in addition to having good texture, and outstanding thixotropic and thermal reversibility properties. These properties are quite similar to those of commercial petrolatum. This work demonstrates that the natural phytosterol-oleogels in edible oils can be a novel source of sustainable and green replacements for petrolatum.

Graphical Rocket man : New [imidazolyl−amine−BH 2 ]-cation-based hypergolic ionic liquids exhibit hypergolic properties upon contact with an oxidizer. Of the new ionic liquids, seven dicyanamide-based ionic liquids are water-stable and have ID<50 ms. Compared to traditional hypergolic ionic liquids, they exhibited shorter ID times and higher densities, thus suggesting their potential application in liquid bipropellant fuels or formulations. The application of hypergolic ionic liquids as propellant fuels is a newly emerging area in the fields of chemistry and propulsion science. Herein, a new class of [imidazolyl−amine−BH 2 ] + -cation-based ionic liquids, which included fuel-rich anions, such as dicyanamide (N(CN) 2 − ) and cyanoborohydride (BH 3 CN − ) anions, were synthesized and characterized. As expected, all of the ionic liquids exhibited spontaneous combustion upon contact with the oxidizer 100 % HNO 3 . The densities of these ionic liquids varied from 0.99–1.12 g cm −3 , and the heats of formation, predicted based on Gaussian 09 calculations, were between −707.7 and 241.8 kJ mol −1 . Among them, the salt of compound 5 , that is, (1-allyl-1H-imidazole-3-yl)−(trimethylamine)−dihydroboronium dicyanamide, exhibited the lowest viscosity (168 MPa s), good thermal properties ( T g <−70 °C, T d >130 °C), and the shortest ignition-delay time (18 ms) with 100 % HNO 3 . These ionic fuels, as “green” replacements for toxic hydrazine-derivatives, may have potential applications as bipropellant formulations.

Most infant formula oils differ significantly from human milk fat (HMF) in structure and composition , which is detrimental to the development of infants. In this study, the lipid compositions of Carassius auratus oils (CAOs) from seven provinces of China were systematically analyzed, and the potential of CAO for use in human milk fat substitutes (HMFS) was evaluated. First, the main fatty acids in most CAOs were confirmed to be palmitic, oleic and linoleic acids . It is interesting to find that 57.08–69.27% of palmitic acid tended to be located at the sn -2 position, which showed a consistency with HMF. Afterwards, content of C52 triacylglycerol in CAOs from three regions exceeded 45%. Finally, a HMFS containing CAO from Jiangsu province was prepared by physical blending and it was verified to have a high similarity with HMF after similarity evaluation, which can provide a reference for the application of CAO in infant formulas.

Graphical It's only natural : Surface-charged bamboo cellulose fibers have been prepared and assembled into an all-natural bulk structural material that shows excellent strength and fracture toughness with low thermal expansion and high fire resistance, making it a potential candidate to partly substitute petroleum-based plastics. Bamboo is widely distributed, rapidly regenerable, and incorporates long cellulose fibers, which make it one of the most lightweight and strong natural materials. Processing bamboo into a high-performance structural material for plastic replacement is highly promising but challenging. In this study, an all-natural, high-performance structural material is derived from natural bamboo with superior mechanical and thermal properties that benefit from the introduction of surface charge and further layer-by-layer assembly of bamboo cellulose fibers. The obtained modified bamboo fiber plate (MBFP) transcends the constraints of the natural size and anisotropy of bamboo, showing high flexural strength (ca. 179 MPa) and flexural modulus (ca. 12 GPa). Moreover, the product has an extremely low coefficient of thermal expansion (ca. 11.3×10 −6 K −1 ), high thermal stability, and superior fire resistance. The excellent mechanical and thermal properties combined with the efficient and rational manufacturing process make MBFP a powerful plastic alternative for furniture, construction, and automotive industries.
