Polymeric polyphenols in different parts (fruits, leaves and calyces) of persimmon ( Diospyros kaki L. cv. Mopan) were characterized via four different degradation methods, followed by HPLC/UPLC-UV/vis, HPLC/UPLC-Q-Exactive-Orbitrap/MS and UPLC-QqQ/MS to obtain comprehensive structural constituent unit information of polymeric polyphenols. The results indicated that persimmon polymeric polyphenols not only consisted of proanthocyanidins as terminal and extension units, but also contained anthocyanidins, flavonols and phenolic acids as terminal units. Among these different fragments detected, (−)-gallocatechin, (−)-gallocatechin-3- O -gallate, (+)-catechin and (+)-catechin-3 -O- gallate as extension units and (−)-epicatechin, (−)-gallocatechin, (−)-epigallocatechin, eight phenolic acids and four flavonols as terminal units were found for the first time in persimmon polymeric polyphenols. The molar percentages of constitutive units of persimmon polymeric polyphenols varied considerably. Compared to polymeric polyphenols in persimmon fruits and calyces, anthocyanidins, flavonols and phenolic acid units with the highest molar percentages were found in polymeric polyphenols in persimmon leaves. In contrast, the mean polymerization degrees of polymeric polyphenols in persimmon fruits, leaves and calyces were 26.45 ± 0.43, 6.23 ± 0.08 and 11.60 ± 0.07, respectively. These findings provide, for the first time, comprehensive structural information on persimmon polymeric polyphenols, and offer valuable insights into their composition and characteristics.

Herein, using dialdehyde waste paper (DAWP) as a cross-linking agent to immobilize persimmon tannin (PT) was first used to remove the U(VI) and Cr(VI) via the “waste control by waste” concept. The microscopic and macroscopic surface properties of the as-prepared adsorbent was characterized by the advanced characterization techniques. Factors that affected the elimination process such as variable pH, coexistence ions and equilibrium time were investigated by batch techniques. The results showed that the maximal removal capacities of U(VI) and Cr(VI) on DAWP-PT were 242.3 mg/g (pH = 6.0) and 178.7 mg/g (pH = 2.0) at 298 K, which exhibited competitiveness with most of the reported solid materials. Meanwhile, adsorption data were fitted perfectly to the Langmuir and Pseudo-second-order equations, which indicated that the monolayer and homogenous chemisorption dominated the removal process. The SEM-EDX, DFT and XPS analysis conformed that adsorption of U(VI) was mainly via surface complexation, while the elimination of Cr(VI) was a redox reaction process, and about 65.33% of Cr(III) and 34.67% of Cr(VI) co-existed onto the surface of DAWP-PT. Thus, this study would provide a high-efficiency and low-cost adsorbent for radionuclide and heavy metal treatment.

A gallium ion-imprinted material (Ga-IIP-PP) was fabricated from persimmon peel using persimmon tannin as a functional monomer. Thereafter, it was applied for the selective adsorption of Ga ions from aqueous solutions containing other metal ions. The sorbent morphology and surface characterization data confirmed the successful loading of a gallium-imprinted layer onto the waste persimmon peel. The imprinted material exhibited a relatively smooth structure with few wrinkles, a negatively charged surface, and a low number of hydroxyl surface functional groups. The results of adsorption experiments revealed that Ga-IIP-PP could be applied in a wide range of Ga concentrations, while its highest adsorption capacity of 128 mg/g and adsorption rate of 0.0081 min −1 were achieved at pH = 3. Moreover, the synthesized Ga-IIP-PP exhibited high selectivity toward Ga ions even in binary systems with similar competitive ions. Finally, Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy were performed to elucidate the adsorption mechanism of Ga ions onto the Ga-IIP-PP surface, which primarily involved electrostatic adsorption and the cation exchange between the H + ions of OH/ COOH groups and Ga ions. This work demonstrates that the bio-sorbent prepared from waste persimmon peel is a promising adsorbent for recovering Ga ions from aqueous solutions.

In this study, a novel porous carbon (PC) is prepared from persimmon fruit via hydrothermal treatment at 140 °C, product freeze-drying and finally carbonization at 550 °C for 4 h under an inert atmosphere. A further porous carbon material containing magnetite nanoparticles (denoted as Fe 3 O 4 -PC) is also prepared from persimmon by introducing a microwave-assisted step into the PC synthesis. Characterization of the PC and Fe 3 O 4 -PC materials reveals that both materials have high specific surface areas and very porous structures, with the Fe 3 O 4 nanoparticles in Fe 3 O 4 -PC possessing a yolk-shell structure. The energy storage performance of the PC and Fe 3 O 4 -PC products is evaluated by assembling a supercapacitor with Fe 3 O 4 -PC as the anode and the PC as the cathode. The results suggest that the PC hold a high areal capacitance of 816.8 mF/cm 2 at 20 mV/s. The adsorption experiment also been performed to investigate the adsorption performance of prepared PC and Fe 3 O 4 -PC. The results suggest that 100% of As (V) in water and 98.3% of As (V) in mud can be removed with Fe 3 O 4 -PC as the absorbent.

The utilization of biomass is an important approach to supplying sustainable carbon sources for green chemistry, by which the product could be more environmentally friendly and lower toxicity. In this work, the local fruit Mopan persimmons were used to be a carbon source to prepare carbon quantum dots (MP-CQDs) via the hydrothermal method. A series of characteristics were applied to the carbon dots to study the structural and optical properties. The results demonstrated that the MP-CQDs were well synthesized and coated by N, O-related surface functional groups. The PL of MP-CQDs showed an excitation-dependent behavior, whose peak shifted from 446 nm to 545 nm under the excitation wavelength from 350 nm to 450 nm. After a selectivity study on different metal ions, we found that MP-CQDs were sensitive to Fe 3+ ions, and the limit of detection (LOD) was determined as 0.324 μM with the 3σ rule. Further, by mixing MP-CQDs with sugar, we successfully applied MP-CQDs to the anti-counterfeiting field by painting anti-counterfeiting patterns with the combination of commercial fluorescent ink (CFI) and MP-CQDs@sugar ink (MPI). The pattern can present different fluorescent properties under 365 nm, 395 nm, and 450 nm respectively. The results revealed that biomass-derived MP-CQDs were a promising candidate for Fe 3+ ions detection and anti-counterfeiting application.

In the study, the structure properties of persimmon pectin (PP) affecting the interfacial performance were characterized firstly. Then, the interfacial behavior of PP at the oil-water interface was evaluated by interfacial tension and interfacial shear/dilatational rheology. Further, the emulsifying and emulsion stabilizing capability of PP were explored based on structure elucidation and interfacial characterization. Structural elucidation of PP indicated that structural characteristics, including high-methylated (71.93 ± 1.23%), lower Mw (4.789 × 10 4 g/mol), and abundant hydrophobic substances including acetyl-groups (1.21 ± 0.09%), protein (11.54 ± 0.75 mg/g), and ferulic-acid moieties (2.47 ± 0.13 mg/g), contributed to its rapid adsorption to the oil-water interface. Additionally, PP was rich in both homogalacturonan (62.42 ± 1.12%) and rhamnogalacturonan-I (17.75 ± 0.48%) domains, favoring i t adsorbe d at the oil-water interface. Of all tested emulsifier solutions (1.0%–3.0%, w/v), PP exhibited potent tension-lowering capacity. Additionally, a strong viscoelastic layer of PP (1.0%, w/v) was formed at the oil-water interface based on the interfacial shear (interfacial adsorption and dynamic strain sweep) and interfacial dilatational rheology (interfacial viscoelasticity, frequency and amplitude sweep). Notably, PP exhibited promising emulsifying and emulsion-stabilizing potential, as reflected by small droplet size, creaming thickness (0.68 ± 0.00 mm), and high emulsifying capacity (63.22 ± 1.58%), turbidity (0.37 ± 0.00), etc. By using multi-techniques and multi-scale analysis, the present work effectively correlated the interfacial, structural, droplet characteristics, and bulk emulsion of PP. Results suggested that PP exhibited a promising emulsification potential and could be developed as a novel polysaccharide emulsifier in the food industry.

This study investigated the structural and functional characteristics of two different molecular weight persimmon pectin extracted from unripe persimmon (PP-1) and ripe persimmon (PP-2). The molecular weight was determined as 117.8 kDa and 61.3 kDa for PP-1 and PP-2, which consisting of glucose, rhamnose, mannose, galactose, and xylose. AFM results indicated PP-1 with many linear chains, and short chains in while short chains, branching points, and heterogeneous clumps were found in PP-2. Emulsion characterization and storage stability experiments revealed that PP-1 with more stable emulsifying properties than PP-2 and commercial citrus pectin. In vitro fermentation of PP-1 and PP-2 by gut microbiota indicated that PP-1 and PP-2 groups were higher than inulin group in total SCFAs production after 48 h of fermentation. This study provided useful information for high value utilization of persimmon pectin.

Rare earth elements (REEs) are used for the development of new energy materials owing to their intrinsic physicochemical property. However, excess REEs in water threaten the safety of animals, plants and humans. An efficient way to separate REEs from the water is therefore needed. In this study, a biosorbent consisting of iron oxide (Fe 3 O 4 ), persimmon tannin (PT), and graphene oxide (GO) as Fe 3 O 4 /PT/GO was prepared, and the adsorption of trivalent erbium (Er 3+ ) ions from aqueous solution was investigated. The adsorption process for Er 3+ ions conforms to pseudo-second order kinetic and the Langmuir isotherm model behavior. Thermodynamic studies indicate that the adsorption process is spontaneous and endothermic. Scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier-transform infrared (FT-IR) spectroscopy, Brunauer-Emmett-Teller (BET) analysis, and vibrating sample magnetometer (VSM) were used to assess the adsorption mechanism of Er 3+ ions onto the Fe 3 O 4 /PT/GO biosorbent. A combination of electrostatic interactions , redox reactivity and chelation are responsible for adsorption of Er 3+ ions on the Fe 3 O 4 /PT/GO biosorbent. The magnetic Fe 3 O 4 /PT/GO biosorbent can be easily separated under the magnetic field for effective recycle of Er 3+ ions from aqueous solution. Therefore, this new biomass composite holds great promise for wastewater treatment.

Graphical The cotton fabrics dyed with aqueous Diospyros mollis Griff extract (DME) has shown a high color fastness to washing, light, and rubbing, antibacterial ability against E. coli and S. aureus 99.9 %, great UV resistance efficiency, good air permeability, water vapor absorbance, a high tensile property as compared to the cotton fabrics dyed with Remazol deep black RGB active dye. This article focuses on comparing the characteristics of cotton fabric dyed with Diospyros mollis extract (DME) solution and that of cotton fabric dyed with the reactive dye. The parameters of the cotton fabric after dyeing with both types of dyes were assessed, including color strength (K/S), structural morphology, infrared spectrum, antibacterial properties, UV resistance, color fastness to washing, rubbing, light, moisture absorption, breathability, and wastewater indices. The obtained results show that the K/S value of cotton fabric dyed with DME solution is slightly lower than that of cotton fabric dyed with the reactive dye, 18.52 and 19.36, respectively. The cotton fabric dyed with the reactive dye does not exhibit antibacterial activity against Escherichia coli and Staphylococcus aureus , whereas the antibacterial effectiveness against these bacteria for cotton fabric dyed with DME solution is 99.99 %. The UV protection capability of cotton fabric dyed with DME solution is superior to cotton fabric dyed with the reactive dye. The BOD/COD ratio of wastewater from the dyeing process with DME is higher than that of the reactive dye, with values of 0.70 and 0.32, respectively. The findings of this study indicate the superior ability of using DME solution as compared to the reactive dye, which is promising as a natural dye for fabric in medical applications.

A study was conducted to investigate the effects of oak chips on the quality of persimmon brandy. The brandy was prepared from Mopan persimmons through fermentation and distillation, and aged for 30–210 days with 0, 5, 10, and 15 g/L of oak chips. The brandy was analyzed for total phenols, oxidation resistance, color, volatile compounds, and non-volatile compounds. Results showed that the addition of oak chips increased the total phenolic content and DPPH scavenging capacity of the brandy. The brandy achieved a better golden yellow color when aged with 10 and 15 g/L of oak chips. HS-SPME-GC-MS analysis revealed 14, 22, 26, and 21 compounds in the four brandy samples with different amounts of oak chips. The brandy aged with 10 g/L of oak chips had the highest total content of volatile compounds. LC-MS-based metabolomics identified a total of 618 non-volatile metabolites, with 20 having the highest relative expression when aged with 10 g/L of oak chips. These findings suggest that persimmon brandy achieves better quality and flavor when aged with 10 g/L of oak chips for 210 days.

The poor biological, mechanical and water-resistance properties of sodium alginate/guar gum film (SG) limit its application in food preservation. To overcome this disadvantage, we added β-Cyclodextrin/persimmon pectin-stabilized baobab seed oil Pickering emulsion (BOPE) to enhance the mechanical and water resistance properties of SG film, and added green synthesized silver nanoparticles (AgNPS) and Lycium ruthenicum extract (LA) to improve the biological properties of the film. The properties of BOPE was optimized using Box–Behnken design (BBD). Scanning electron microscope and Fourier transform infrared results revealed the change of structure and molecular interaction in the SG film after the addition of AgNPS, LA, and optimized BOPE. The 2.0%BOPE-loaded film containing AgNPS/LA with the enhanced mechanical, barrier, BO retention, and biological properties not only improved the preservation effect on mushroom ( A. bisporus ), but also maintained structural stability. Thus, the 2.0%BOPE-loaded SG/LA/AgNPS film has considerable potential in active packaging applications.

In this study, the persimmon tannin powder modified polyurethane foam (PTP-PUF) was synthesized. The morphology of the foam was observed by SEM, the thermodynamic stability and mechanical properties of PTP-PUF were discussed for application. The effect of persimmon tannin powder content and initial pH on Cu(II) and Pb(II) biosorption on PTP-PUF was investigated. The adsorption equilibrium data for Cu(II) and Pb(II) fitted the Freundlich model and Langmuir model well, respectively. And the maximum adsorption capacity of PTP-PUFs for Cu(II) and Pb(II) ions were 96.06 and 112.2 mg/g at pH 5 and 323 K. The kinetic data was tested using pseudo-first-order and pseudo-second-order models. The results suggested that the pseudo-second-order model was the best one to describe the adsorption behavior of Cu(II) ( R 2 > 0.997) and Pb(II) ( R 2 > 0.985) onto PTP-PUF.
