This study compared three drying methods for instant green tea (IGT): conventional spray-drying (CSD, inlet air temperature 170 °C, outlet air temperature 78 °C), freeze-drying (FD, initial temperature −45 °C), and electrostatic spray-drying (ESD, inlet air temperature 70 °C, outlet air temperature 38–42 °C).Statistical analysis revealed significant differences in IGT quality among the drying methods. Freeze-dried IGT demonstrated the lowest moisture content (3.6 ± 0.11 %) and water activity (0.23 ± 0.01), with Electrostatic spray-dried IGT showing comparable results, Conventionally spray-dried IGT exhibited significantly higher moisture content. Freeze-dried IGT achieved the highest yield (42 ± 0.32 %) and solubility, while Electrostatic spray-dried IGT (38 ± 0.27 %) outperforming Conventionally spray-dried IGT (35 ± 0.43 %). Sensory evaluations indicated that Freeze-dried and Electrostatic spray-dried IGT exhibited more balanced flavors, Electrostatic spray drying IGT scored closely to Freeze-dried IGT in astringency (4.92 ± 0.10 vs 5.77 ± 0.15) and bitterness (4.23 ± 0.06 vs 4.74 ± 0.15), with both significantly outperforming Conventionally spray-dried IGT (p < 0.05). Chemical analysis showed Freeze-dried IGT retained the highest levels of caffeine (7.74 ± 0.01 mg/g), amino acids (231.99 ± 0.36 mg/g), gallic acid (1.55 ± 0.52 mg/g), and total polyphenols (301.3 ± 8.16 mg/g), followed by Electrostatic spray-dried IGT. Conventionally spray-dried IGT showed significantly lower concentrations. Antioxidant capacity followed the order Freeze-dried IGT > Electrostatic spray-dried IGT > Conventionally spray-dried IGT, consistent with polyphenol content. Volatile compound analysis identified 103 aroma compounds in Freeze-dried IGT, 66 in Electrostatic spray-dried IGT, and 32 in Conventionally spray-dried IGT. Odor activity value (OAV) analysis determined 13 key aroma compounds, including linalool, β-damascenone, geraniol, and decanal, as well as benzeneacetaldehyde, nonanal, and (E,E)-2,4-heptadienal, critical contributors to the chestnut-like aroma. The total concentration of these compounds showed a trend of Freeze-dried IGT > Electrostatic spray-dried IGT > Conventionally spray-dried IGT, aligning with sensory evaluation results for chestnut-like aroma intensity. Overall, the three drying methods significantly impacted IGT quality. Research shows that electrostatic spray drying is more suitable than conventional spray drying for producing high quality and high fidelity IGT, when using high-quality tea raw materials, with product quality close to that of freeze dried IGT. Thus, electrostatic spray drying offers a novel method for manufacturing high quality instant green tea.

The sensory qualities , aroma profile, and microstructural features of instant Pu-erh teas (IPTs) produced by electrostatic spray drying (ESD) were evaluated by sensory and instrumental analyses and compared with those produced by other drying methods (freeze-drying [FD], vacuum drying [VD], and conventional spray drying [CSD]). The sensory qualities of ESDIPT were similar to those of FDIPT, and better than those of VDIPT and CSDIPT. Eighty-eight volatiles were detected in all IPTs, and 45 odor-active compounds were captured. Most of their OAVs were higher in ESDIPT than in VDIPT and CSDIPT but were lower than those in FDIPT. Dihydro-β-ionone had the highest OAV. Aroma recombination experiments were performed to verify the identification results. ESDIPT was present in the shape of microspheres with many regular concave surfaces, which was different from those treated by other drying methods. In terms of sensory quality and productivity, ESD would be a potential method for IPT production.

The memory effect of lithium-ion batteries (LIBs) was first discovered in LiFePO4, but its origin and dependence are still not clear, which is essential for regulating the memory effect. In this paper, a home-made spray drying device was used to successfully synthesize LiFePO4with an average particle size of about 1 μm, and we studied the influence of spray drying temperature on the memory effect of LiFePO4in LIBs. The results showed that the increasing of spray drying temperature made the memory effect of LiFePO4strengthen from 1.3 mV to 2.9 mV, while the capacity decreased by approximately 6%. The XRD refinement and FTIR spectra indicate that the enhancement of memory effect can be attributed to the increment of Li–Fe dislocations. This work reveals the dependence of memory effect of LiFePO4on spray drying temperature, which will guide us to optimize the preparation process of electrode materials and improve the management system of LIBs.Keywords:LiFePO4;spray drying method;memory effect;cathode materials

Microencapsulation is a widely-investigated technique used for the unstable material preservation since the wall materials prevent the core materials from loss and deterioration. To improve the stability of cinnamaldehyde (CAL), different microcapsule wall systems are fabricated by spray-drying, and then characterized by experimental methods to determine the most suitable wall materials. Surface morphology, encapsulation efficiency, effective loading capacity, as well as moisture absorption property are evaluated, and the results suggest that a three-matrix system of methyl cellulose (MC)/sodium alginate (SA)/MC or MC/carboxymethyl chitosan (CMC)/SA wall formulation is more suitable for CAL microencapsulation. Moreover, a novel quantitative method is also proposed to verify the most stable wall material microencapsulation. The quantitative results show that the highest activation energy (53.00 ± 2.24 kJ/mol) is observed for the MC/CMC/SA-encapsulated CAL microcapsule. Taken together, the results suggest that MC/CMC/SA wall formulation shows excellent barrier properties and is superior to other wall materials in preventing microencapsulated CAL deterioration. This study will be efficient in designing an ideal capsule for CAL microencapsulation.

To enhance Lactobacillus paracei F50 viability during spray drying and long-term storage, this study evaluates whey protein (WP) crosslinked with four polysaccharides (κ-carrageenan (KC), xanthan gum (XG), low-methoxyl pectin (LMP), sodium alginate (SA)) for the first time as protective matrices for L. paracasei F50 during spray drying. The four kinds of crosslinked wall materials were compared by various characterization methods. Among them, the WP-κ-carrageenan (WP-KC) composite exhibited optimal performance, forming a uniform microcapsule with high colloidal stability. After spray drying, WP-KC achieved the highest viable cell density (9.62 lg CFU/g) and survival rate (91.85%). Notably, WP-KC maintained viability above 8.68 lg CFU/g after 120 days of storage at 4 °C, surpassing other formulations. Structural analysis showed that the WP-KC microcapsule was completely encapsulated without breaking or leaking and confirmed the molecular interaction between WP and KC. Under the condition of high temperatures (≤142.63 °C), the wall material of the microcapsule does not undergo any endothermic or exothermic process and is in a state of thermodynamic equilibrium, with excellent stability and good dispersion. Additionally, microcapsules exhibited enhanced resistance to thermal stress (55–75 °C) and UV irradiation, higher than that of free cells. These results highlight WP-KC as an industrially viable encapsulation system for improving probiotic stability in functional foods, offering critical insights into polysaccharide–protein interactions for optimized delivery systems.

Lithium-sulfur battery (LSB) will become the next generation energy storage device if its severe shuttle effect and sluggish redox kinetics can be effectively addressed. Here, a unique three-dimensional hollow reduced graphene oxide microsphere decorated with ZnO nanoparticles (3D-ZnO/rGO) is synthesized to decrease the dissolution of lithium polysulfide (LiPS) into the electrolyte. The chemical adsorption of ZnO on LiPS is combined with the physical adsorption of 3D-rGO microsphere to synergistically suppress the shuttle effect. The obtained 3D-ZnO/rGO can provide sufficient space for sulfur storage, and effectively alleviate the repeated volume changes of sulfur during the cycle. When the prepared S-3D-ZnO/rGO was used as the cathode in LSB, an initial discharge specific capacity of 1277 mAh g−1was achieved at 0.1 C. After 100 cycles, 949 mAh g−1can still be maintained. Even at 1 C, a reversible discharge specific capacity of 726 mAh g−1was delivered.Keywords:ZnO;graphene;spray drying;hollow structure;lithium-sulfur battery

Potato starch (PS), a naturally occurring carbohydrate biopolymer, is commonly used in the meat industry to enhance the processing and nutritional properties of meat products. This study utilizes spray drying to produce PS-based powders for the production of 3D printed beef products. The effects of incorporating PS-based materials at 1% concentrations into beef pastes are investigated, focusing on the impact on product texture, cooking properties, printing accuracy, freeze-thaw stability, and color. Additionally, the suitability of the 3D printed beef products for individuals with dysphagia is assessed using the International Dysphagia Diet Standardization Initiative (IDDSI). The 3D printed beef products containing PS-based powders are successfully manufactured and maintained their structure during printing and cooking. The addition of these powders improve moisture content, cooking yield, lightness, and reduced diameter reduction, redness, hardness, cohesiveness, and chewiness. Moreover, the results suggest that P-N, can be classified as potential level 6 diets (soft and bite-sized) according to the IDDSI framework.

Soy peptide solution (40%, w/w) was successfully encapsulated in a W 1 /O/W 2 double emulsion produced by a two-step emulsification process. Polyglycerol polyricinoleate (PGPR) was found to be an effective inner emulsifier compared to Span 60 and lecithin to produce stable W 1 /O primary emulsion. The primary emulsion was subsequently emulsified into an outer aqueous phase (W 2 ) containing octenyl succinic anhydride (OSA) starch and maltodextrin. The droplet size and encapsulation efficiency of the peptide solution in W 1 /O/W 2 emulsion were found to depend on the W 1 :O ratio, peptide concentration in the inner W 1 phase and homogenization condition of the secondary emulsification step. The double emulsion with the highest encapsulation efficiency (>80%) was prepared by: (i) using 40% (w/w) soy peptide solution as W 1 phase; (ii) controlling W 1 :O ratio at 3:7 (w/w) and (iii) homogenizing the emulsion at 10,000 rpm for 3 min. The freeze-dried microcapsule powder of W 1 /O/W 2 emulsion showed higher encapsulation efficiency (>70%) compared to spray-dried one. The freeze-dried microcapsule of W 1 /O/W 2 double emulsion developed in this study is a promising delivery matrix to encapsulate hydrophilic ingredients including peptides. Fourier-transform infrared spectroscopy (FTIR) spectra of the microcapsule powder indicated good compatibility between peptide and encapsulants.

Peptide aggregation inevitably occurs during hydrolysis, and insoluble peptide aggregates (ISPA) are used as feed for animals due to their poor water solubility and unpleasant bitter flavor. Ultrasound was used to fabricate soy peptide nanoparticles by reassembling ISPA, followed by spray-drying encapsulation to develop low-bitterness peptide microcapsules with soluble soybean polysaccharide (SSPS) and stevioside (STE) as wall materials. Powder properties, bitter taste, and the morphology of the microcapsules were evaluated. The formation of soluble peptide nanoparticles (<200 nm) was observed after ultrasound due to the reassembly of ISPA through the disruption of non-covalent intermolecular interactions. A gradual reduction in bitter taste was observed with increasing ultrasonic time. Moreover, spray-drying encapsulation with STE could effectively improve the flowability and wettability of the microcapsule powder owing to the rapid migration of surface-active STE to the atomized droplet surface, as evidenced by the lower angle of repose and wettability time. Peptide microcapsules with STE (spherical particles with smooth surfaces) exhibited lower density and reduced bitterness because STE (0–0.1%,w/w) exhibited an excellent bitter-masking effect. With high STE concentrations (>0.5%,w/w), microcapsules exhibited a higher bitter taste than unencapsulated peptides due to the increased surface distribution of STE on the microcapsules. These results provide an effective technique to improve the physicochemical properties of ISPA.

Mesoporous graphene and other carbon derivative nanospheres have attracted intensive research attention owing to their many unique characteristics and fascinating properties. However, facile synthesis of these mesoporous nanospheres with a small particle size and controllable morphology is still a grand challenge. Herein, we report a Kirigami-inspired approach to prepare mesoporous spherical graphene oxide (MSGO) particles through spray drying of holey GO sheets. By increasing pore size and porosity of the holey GO sheets, the spray-dried particles underwent the transition from rough crumpled structure to smooth spherical shape. The prepared MSGO particles have tunable diameters smaller than 200 nm and a high specific surface area of 503 m 2 /g, which enable consistent high-efficiency physical adsorption removal of organic dyes such as Rhodamine B from polluted water with a high adsorption rate of 335.6 mg/(g min). Moreover, the reported synthetic route provides the freedom to easily incorporate other functional nanoparticles such as TiO 2 , CuO or post-dope MSGO with nitrogen elements for construction of multifunctional composite particles with tailorable structures, which may enable a broad range of promising applications.

Hierarchical Na 2 FeP 2 O 7 spheres with nanoparticles were successfully fabricated by a facile spray drying method. A relatively low drying temperature was introduced in order to form a carbon layer on the surface. As a cathode material for sodium-ion batteries, it delivered a reversible capacity of 84.4 mAh g −1 at 0.1 C and showed excellent cycling and rate performance (64.7 mAh g −1 at 5 C). Furthermore, a full sodium battery was fabricated using SP-Na 2 FeP 2 O 7 as the cathode and hard carbon as the anode, suffering almost no capacity loss after 400 cycles at 1 C. Due to its superior electrochemical property and the low materials cost, Na 2 FeP 2 O 7 is becoming a promising cathode material for large-scale energy storage systems.

In this work, the mono-dispersed and high-flowable AlON spherical powders were obtained for the first time. Spherical pure AlON particles with a mean size of approximately 51.9 μm were prepared from the C/Al 2 O 3 mixture via spray drying technology followed by a calcined step at 1750 °C for 0.5 h. Compared with the irregular-shaped AlON powders obtained by the conventional route, the as-prepared spherical AlON powders present higher flowability and filling properties. The Carr index and Hausner ratio of these AlON powders are 73.5 and 1.13, respectively. This work provides a paradigm for obtaining highly flowing spherical ceramic powders, which is desirable for the preparation of complex-shaped AlON ceramics.
