Botryosphaeria dothidea, a notorious plant pathogen, is responsible for causing chestnut rot during postharvest storage. This research aimed to assess the antifungal properties of perilla essential oil (PEO) and perillaldehyde (PAE) againstB. dothidea. PEO’s and PAE’s inhibitory effects onB. dothideawere investigated using an agar dilution method, a fumigation method, and an in vivo assay in chestnuts and shell buckets. Based on the results of gas chromatography-mass spectrometry, it was confirmed that the main component of PEO was elemicin. The antifungal mechanism of PEO and PAE againstB. dothideawas investigated by conducting staining experiments of the fungal cell wall and cell membrane. PEO and PAE strongly inhibit the mycelial growth ofB. dothideain a dose-dependent manner. The inhibitory mechanism is mainly related to the destruction of the integrity of the fungal cell wall and plasma membrane. Notably, PEO retains its antifungal efficacy againstB. dothideain chestnuts, effectively prolonging their storage life. These findings indicate that PEO and PAE are nontoxic, eco-friendly botanical fungicides, holding promise for controlling postharvest chestnut rot.

Chestnuts, despite their nutritional value, pose challenges in starch processing, digestion, and absorption. This study employed various color-fixing formulations and processing methods to simulate the in vitro digestion of both untreated and enzymatically hydrolyzed chestnut flour. Changes in starch properties, digestion characteristics, and estimated glycemic index (eGI) were analyzed to understand how enzymatic hydrolysis affects chestnut flour properties. The results showed that the browning of chestnut flour was the least when the mass ratio of vitamin C, citric acid, and EDTA-Na 2 was 9:1:0.3. Following treatment with pullulanase and glucoamylase, the content of rapidly digestible starch decreased to 10 %, while the content of slowly digestible starch and resistant starch increased to 62 % and 27 %, respectively. The eGI value of chestnut flour after enzymatic hydrolysis increased to 61.85–65.14, the hydrolysis rate was 78.37 %–89.20 %, the water holding capacity was 5.3–8.6, the solubility was 51.33 %–58.33 %, and the swelling degree decreased to 2.21–3.33 mL/g.

The preparation of biomass-derived porous carbon having a high specific surface area for high-performance supercapacitors has been recognised as an important research topic in the past decade. In this study, chestnut-pulp-derived porous carbon is prepared by employing a two-step process involving carbonisation and KOH chemical activation for the first time. The synthesized hierarchical porous carbon samples have an ultra-high specific surface area of 2646 m 2 g −1 and good conductivity, and their O-doping can be controlled. They exhibit excellent electrochemical performance as carbon electrodes owing to the synergistic effects of their advantageous features. In a three-electrode system, the as-obtained electrode yields a high specific capacitance of 373 F g −1 at 0.5 A g −1 in 6 M KOH electrolyte. Furthermore, it exhibits excellent rate performance with ~70.8% capacity retention when the discharge current increases from 1 to 10 A g −1 and prominent cycling stability with ~99.7% capacity retention after 10000 cycles. These values indicate that chestnut-pulp-based carbon materials have excellent electrochemical properties when used as supercapacitor electrodes and may promote the large-scale application of 3D porous carbons in energy storage.

Traditional glutinous rice wine (TGRW) has been fermented in China for over 9000 years. Recently, an innovative regional variation of TGRW, chestnut rice wine, banli mijiu (BLMJ), was developed by adding Chinese chestnut (Castanea mollissimaBlume) into the fermentation brew. The objective of this study was to characterize the effects of chestnut on the nutritional, aromatic, and antioxidant properties of TGRW. To compare the aromatic sensory profiles between TGRW and BLMJ, the free amino acids and ethyl carbamate, phenolic, and flavonoid contents were determined. In addition, the antioxidant properties, including reducing power, metal chelation, and free radical scavenging activities, were also compared. A total of 98 distinct flavor components were identified in BLMJ, among which 38 were detected by sniffing instrument, compared to 77 distinct flavor components in TGRW. BLMJ thus contains a wider range of flavor components, but similar alcohol, acid and reducing sugar profiles compared with TGRW. Twenty-five free amino acids were detected in both wines, with lower contents of each in BLMJ compared with TGRW. BLMJ also exhibited stronger antioxidant properties than TGRW. The findings of this study suggest that chestnut can increase the diversity of aromatic components and improve antioxidant qualities of traditional rice wine.Keywords:chestnut;rice wine;amino acid;antioxidant activity;phenols;sensory components

Thymol (TMO) was loaded into chitosan nanoparticles (CSNPs) to inhibit chestnuts decay during storage. Three chestnut treatments were evaluated, including the CK (uncoated control), CSNPs (coated with chitosan nanoparticles), and TMO-CSNPs (coated with thymol-loaded chitosan nanoparticles). Quality assessments of chestnuts were conducted periodically for up to 180 days, which included starch content, amylase activity, water content, respiration rate, weight loss rate, microbiological indicators, decay rate, and quality evaluation. Results indicated that TMO-CSNPs had significantly less nutrient loss in soluble sugar (10.61%) and starch content (27.72%) compared with CK, which was attributed to low metabolic activities as evident in low amylase activity and respiration rate. Moreover, TMO-CSNPs significantly inhibited the growth of mold and yeast (4.17 log CFU g −1 on day 180) and kept the lowest decay rate (5.33%). This study demonstrates the potential of food nanomaterial as an alternative strategy to promote food security and supply chain resilience.

Bio-based aerogels have attracted much attention due to their biodegradability and excellent oil-water separation properties. However, the preparation of inexpensive green aerogels with high separation efficiency is still a great challenge. In this paper, low-density, high-adsorption capacity and superhydrophobic chestnut shell-based bio-aerogels were prepared by chemical cross-linking and chemical vapor deposition using agricultural and forestry waste chestnut shells as the precursor of aerogels to achieve high efficiency of oil-water separation and to achieve the goal of “treating waste with waste”. The covalent cross-linking of chestnut shell cellulose and cross-linking agent to form silicone-containing functional groups improved the pore structure, hydrophobicity and mechanical properties of chestnut shell cellulose, and under the action of capillary force, the oil was retained in the pores of the bio-aerogels, which achieved the selective adsorption of oil and organic solvents in the oil-water mixture, with a separation efficiency of more than 98 %. After 10 cycles, the bio-aerogel still has good reusability. This eco-friendly and low-cost aerogel provides a practical method for resource conversion and recycling, as well as a green and innovative way for the treatment of oily wastewater.

The yellowing and quality deterioration are important factors to shorten the storage period of peeled water chestnuts (PWCs). Integration of 4-OH-7-C 3 HO-coumarin and controlled atmosphere (CA) storage (Ne, O 2 ) to extend the storage period of PWCs has not been studied. The objective of the investigation was to reveal the mechanics with that integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ) extended the storage period of PWCs. PWCs were treated with 4-OH-7-C 3 HO-coumarin (1.2 %), CA storage (81.2 % Ne, 18.8% O 2 ), and integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ). The yellowing degree, weight loss, yellowing substance contents, enzymatic activities, total soluble solids content, titratable acidity content, ascorbic acid content, and microbe of PWCs were detected. 4-OH-7-C 3 HO-coumarin (1.2 %), CA storage (81.2 % Ne, 18.8 % O 2 ), and integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ) extended the storage period by 3, 9 and 12 d. Integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8% O 2 ) was the best. On day 12, integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ) reduced the yellowing degree from 99.5% to 0, the peroxidase activity from 35,603.37 to 28,504.61 U s −1 kg, the eriodictyol content from 3.09 × 10 −4 % to 0, the weight loss from 5.24 % to 0. Integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ) increased the total soluble solids content from 9.37 % to 13.49%, the titratable acidity content from 5.67 × 10 −3 % to 8.62 × 10 −3 % , and the titratable acidity content from 8 × 10 −5 % to 8.55 × 10 −5 %. Integration of 4-OH-7-C 3 HO-coumarin (1.2 %) and CA storage (81.2 % Ne, 18.8 % O 2 ) can be employed to extend the storage period of PWCs. This study provided a theoretical basis for the practical application of integration of 4-OH-7-C 3 HO-coumarin and CA storage (Ne, O 2 ) to extend the storage period of PWCs.

Chestnut shells in large amounts are significantly underutilized agricultural and forestry waste that can be exploited as a resource for the production of high-valued nature active compounds. In this study, an efficient and green approach was established to extract and recover the highly valued phenolic compound, ellagic acid, from waste chestnut shells with choline chloride-based deep eutectic solvents (DESs). By utilizing optimized ultrasonic-assisted extraction conditions with choline chloride/n-propanol DES, solid–liquid ratio of 40 mg/mL, extraction time of 70 min and extraction power of 200 W, highly efficient extraction value for ellagic acid of 4.64 mg/g was obtained. Meanwhile, ellagic acid was recovered easily with a recovery percentage of 94.9% by anti-solvent precipitation method through the denaturation of DES with water. The purity of ellagic acid in the extracts reached 85.6%, which is more than two times to that via ethanol extraction methods (36.4%). In addition, the recovered ellagic acid exhibited strong antioxidant activity with IC 50 (0.309 mg/mL) and significant antibacterial activity with Minimal inhibitory concentration (MIC) (250 mm) and diameter of inhibition zone (DIZ) (17.60 μg/mL). The anti-solvent precipitation method could denature DES, led to higher extraction and recovery efficiency and high-purity ellagic acid simultaneously in one step. The novel method is of great significance to the whole chestnut production process for the utilization of waste chestnut shells. Furthermore, this method can also be used as a green, pollution-free alternative method for the extraction and recovery of phenolic components from natural resources for pharmaceutical and biochemical applications.

This study investigated the formation and molecular interaction mechanism of chestnut starch nanocrystal (SNC)/macadamia protein isolate (MPI) complexes and their application in edible oil-in-water Pickering emulsion (PE). SNC/MPI complexes were characterized by scanning electron microscopy and particle size analyzer. The PEs stabilized by SNC/MPI complexes were characterized by confocal laser scanning microscopy and rheological measurement. The results showed that hydrogen bonds between the two particles significantly affected the secondary structure and assembly of SNC/MPI complexes at the oil/water interface. The optimal mass ratio of SNC to MPI in the complexes with the best stability was determined as 20:1. The formation of edible oil-in-water PEs stabilized by SNC/MPI complexes significantly improved the oxidative and storage stability of different edible oils (olive oil, walnut oil, edible tea oil, and macadamia oil). These different edible oil-in-water PEs stabilized by SNC/MPI could be used as effective carriers of quercetin with their loading rates higher than 93%.Keywords:chestnut starch nanocrystal;macadamia protein isolate;Pickering emulsion;emulsion stability;effective delivery system

The efficient recycling of agricultural chestnut shell waste is of considerable interest due to its large availability and economic feasibility. Herein, an alkaline-activated biochar was thermally prepared using chestnut shell by finely regulating main conditions; its morphological, structural and physic-chemical properties were well characterized. Fenton-like capacity to trigger peroxymonosulfate activation for superior pollutant degradation with high efficiency and good selectivity was validated in different water matrix. Both radical formation and electron transfer were identified as reaction pathways, while the selective non-radical mechanism played the major role in pollutant degradation. Surface ketonic groups were identified as the main reactive sites for non-selective radical production, while crystal edges and structural defects on sp 2 /sp 3 carbon network could smoothly mediate the selective electron transfer from pollutant to oxidant in the non-radical Fenton-like catalysis. The two-mixed radical/non-radical pathways exhibited important advantages for environmental decontamination , in comparison with the one-single radical or non-radical mechanism. Our study provided a promising recycling strategy for agricultural chestnut shell, as well as an environment-friendly catalyst for heterogeneous Fenton-like catalysis in green water purification rendered by the synergistic radical/non-radical reaction pathways.

Surface-enhanced Raman scattering (SERS) has proven to be an effective technique for identifying and providing fingerprint structural information on various analytes in low concentration. However, this analytical technique has been plagued by the ubiquitous presence of organic contaminants on roughened SERS substrate surfaces, which not only often result in poorer detection sensitivity but also significantly affect the reproducibility and accuracy of SERS analysis. Herein, we developed a clean, stable, and recyclable three-dimensional (3D) chestnutlike Ag/WO3–x (0 < x < 0.28) SERS substrate by simple hydrothermal reaction and subsequent green in situ decoration of silver nanoparticles. None of the organic additives were used in synthesis, which ensures the substrate surfaces are completely clean and free of interferences from impurities. The innovative design combines the SERS enhancement effect and self-cleaning property, making it a multifunctional and reusable SERS platform for highly sensitive SERS detection. Using malachite green as a model target, the as-prepared SERS substrates exhibited good reproducibility (relative standard deviation of 7.5%) and pushed the detection limit down to 0.29 pM. The enhancement factor was found to be as high as 1.4 × 107 based on the analysis of 4-aminothiophenol. The excellent regeneration performance indicated that the 3D biomimetic SERS substrates can be reused many times. In addition, the fabricated substrate was successfully employed for detecting thiram in water with a detection limit of 0.32 nM, and a good linear relationship was obtained between the logarithmic intensities and the logarithmic concentrations of thiram ranging from 1 nM to 1 μM. More importantly, the resultant SERS-active colloid can be used for accurate and reliable determination of thiram in real fruit peels. These results predict that the proposed SERS system have great potential toward rapid, reliable, and on-site analysis, especially for food safety and environmental supervision.

In recent years, population aging together with the increased prevalence of diabetes and obesity has fuelled a surge in the instances of cutaneous non-healing wounds. Royal jelly (RJ) is a traditional remedy for wound repair; however, the subjacent mechanisms and ingredient profiles are still largely unknown. Our previous study found that Castanea mollissima Bl. RJ (CmRJ-Zj) possessed superior wound healing-promoting effects on both the in vivo and in vitro models than Brassica napus L. RJ (BnRJ-Zj). This study conducted an in-depth investigation on the wound-repairing mechanisms of CmRJ-Zj and BnRJ-Zj to explain the previously observed phenomenon and also comprehensively characterized their constituents. It was found that chestnut RJ could enhance cutaneous wound healing by boosting the growth and mobility of keratinocytes, modulating the expression of aquaporin 3 (AQP3), regulating MAPK and calcium pathways, and mediating inflammatory responses. By employing LC-MS/MS-based proteomic and metabolomic techniques, the comprehensive molecules present in CmRJ-Zj and BnRJ-Zj were elucidated, resulting in a clear discrimination from each other. A total of 15 and 631 differential proteins and compounds were identified, and 217 proteins were newly found in RJ proteome. With bioinformatic functional analysis, we speculated that some differential components were responsible for the wound-healing properties of CmRJ-Zj. Therefore, this study provides an insight into the wound-healing mechanisms of RJ and is the first to explore the compositions of RJ from different nectar plants. It will facilitate the development of therapeutic agents from RJ to treat difficult-to-heal wounds and the distinction of different RJ categories.
