Cold chain transportation of prefabricated foods mainly relies on sustained mechanical refrigeration with high power consumption and high cost. In this study, a green, safe, efficient and low-cost solution for prefabricated food cold chain based on NaCl@Na 2 SO 4 eutectic brine phase change cold storage gel (BPCCSG) is proposed. BPCCSG is prepared by liquid homogenization, polymer cross-linking and thermal conductive filler dispersion. The phase transition temperature of BPCCSGs is −21.73 °C, which is suitable for refrigeration temperature of a typical type of prefabricated food (shrimp meat). The phase change latent heat and thermal conductivity are as high as 167.64 Jg -1 and 0.856 Wm −1 K −1 , respectively. Gel packaging avoids the leakage of BPCCSGs and its harm to the integrity of prefabricated foods. By optimizing the distribution of BPCCSGs in the cold storage equipment, the temperature uniformity inside the equipment can be effectively improved. The economic benefit of BPCCSG is as low as 5.36 × 10 −4 $J −1 . By introducing 5G sensors, temperature and position of cold storage equipment are monitored in real time. Finally, BPCCSGs are successfully applied in cold chain of shrimp prefabricated foods to effectively guarantee the quality. This work provides forward-looking guidance for next generation of state-of-the-art cold chain solutions for prefabricated foods.

Excessive NaCl intake is harmful to human health, although it is quite common in many foods such as sausages. Recently, spent hen meat hydrolysates (SHH) have been reported to have a salt-taste-enhancing activity; therefore, they could be added as food ingredients to reduce NaCl content. In this work, SHH hydrolysed by papain (P-SHH) and flavourzyme (F-SHH), and their ultrafiltrated fractions (P-UF and F-UF) have been assayed as partial substitutes of salt in Cantonese sausages to get a 30% reduction in salt content. Compared to the direct NaCl reduction, the addition of substitutes, especially F-SHH and F-UF, improved the sensory quality of the sausages, including saltiness, redness, hardness, chewiness, cured-meat flavour, and winey, which were found at levels comparable to those of the control. Direct reduction of NaCl significantly promoted protein oxidation in sausages. However, the degree of protein oxidation in sausages containing hydrolysates or UF was comparable to that of the control, due to the antioxidant activity of the peptides present in the hydrolysates. Moreover, the substitute application, especially P-SHH and P-UF, increased protein digestibility and essential amino acid/total amino acid ratio compared to the group with direct NaCl reduction, likely due to reduced protein oxidation degree and improved proteolytic accessibility. Considering potential industry applications, the F-SHH is more suitable as a NaCl substitute for enhancing sensory quality, while the P-SHH is better for improving digestibility and nutritional value in sodium-reduced Cantonese sausages.

The solubilities and refractive indices in the systems NaCl–Na 2 SO 4 –H 3 BO 3 –H 2 O and NaCl–H 3 BO 3 –H 2 O at 323.15 K were investigated with the isothermal dissolution equilibrium method. The phase diagram of the ternary system consists of two single-salt crystallization fields of NaCl and H 3 BO 3 , two solubility univariant curves, and one invariant point. The dry-salt diagram of the quaternary system is composed of three single-salt crystallization fields corresponding to NaCl, Na 2 SO 4 and H 3 BO 3 , three solubility univariant curves, and one invariant point. A comparison of the diagrams of the quaternary system at (298.15, 323.15 and 373.15) K shows that areas of sodium chloride and sodium sulfate salts region increases whereas the area of H 3 BO 3 region decreases distinctly with temperature increasing. Combining the Pitzer parameters and solubilities in the ternary systems in this study and literatures, the lacking Pitzer parameters for H 3 BO 3 were fitted on the basis of Pitzer model. The calculated solubilities with the model agree well with the experimental data. The phase diagrams and Pitzer model for the quaternary system at 298.15 and 323.15 K were then used to conduct a computer simulation of brine separation. All H 3 BO 3 and most of Na 2 SO 4 can be separated from the solution with segmental evaporation method.

NaCl has been successfully used as a template for the synthesis of 2D nanomaterials, but it is seldom used for the construction of flat small organic molecules. Herein, a simple, low-cost, and highly efficient synthesis of phenazines with planar main frames, such as 5-phenyl-5,14-dihydro-5,7,12,14-tetraazapentacene, in the presence of NaCl micro-crystal as a kind of molecular mold is described. The reactants were mixed with NaCl powder and heated to 320 °C for 5 min. Yields >90% were readily achieved after a simple precipitation in water. The effectiveness of NaCl crystal as a mold with HCl was confirmed by comparison with common inorganic salts, SiO2, and γ-Al2O3 with HCl together with combinations including NaNO3 + HNO3, Na2SO4 + H2SO4, NaH2PO4 + H3PO4, and NaH2PO4 + polyphosphoric acid. The mechanism was deduced with the aid of computer simulation, which confirms the stabilization of 5,14-dihydro-5,7,12,14-tetraazapentacene by the NaCl surface. DMSO solution of a product, 1,3-dihydro-imidazo[4,5-b]phenazin-2-one, showed enhanced fluorescence in H2O, and it was used as a fluorescent probe for pH and Hg2+. A full-color material was prepared by mixing precursors of epoxy resin and phenazines, and its fluorescent color could be adjusted by the ratio of phenazines.

This work successfully synthesized γ-(2,3-glycidoxy) propyltrimethoxysilane (GPTS) functionalized silica nanoparticles (GSiO 2 ). The obtained GSiO 2 was grafted onto lysine-modified graphene oxide (LGO) by covalent bonding to prepare GLGO nano-hybrid material, and then the prepared GLGO nano-hybrid material was used as a nano-filler for the waterborne epoxy resin (WEP) matrix. The fracture surface of the composite film was investigated by SEM, it was observed that GLGO was uniformly distributed in the WEP matrix. In addition, the contribution of GO, LGO and GLGO on the corrosion anticorrosive performance of WEP coatings in 3.5% NaCl(aq) was estimated via potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS). Experimental data exhibited that the impedance modulus of the GLGO/WEP coating system with only 0.1 wt% GLGO added at |Z| f = 0.01 Hz was about two orders of magnitude higher than that of the pure WEP coating after 40 days immersion. Therefore, GLGO nano-hybrid material was an effective green anti-corrosion nano-filler for WEP matrix.

Effects of partial substitution of NaCl with KCl, MgCl 2 or CaCl 2 on oxidative characteristics of myofibrillar protein (MP) in a hydroxyl radical generating system and their heat-induced gel properties were investigated. Results indicated that MP oxidation is dependent upon the different chloride salt types and substitution degree. MP at 0.60 M NaCl was beneficial to protein unfolding and gel quality in the oxidative system. Increased formation of disulfide bonds affected the MP conformation and resulted in a large particle size and an aggregated network of gel at the 50% substitution degree of KCl. The presence of CaCl 2 or MgCl 2 substitutes contributed to protein polymerization and insolubility. MP aggregation restrained the formation of dense and continuous gel networks during heating, and thus resulted in a low-grade gel. Ca 2+ had more serious impact on gel properties than Mg 2+ , dependent on different cation effects. Substitution of 25% NaCl by KCl gave acceptable gel quality in MP.

Coatings with multiple protective properties are highly desired for anti-corrosion purposes as they overcome the limitations of conventional coatings that have limited functionality in field applications. Thus, this study describes the protective mechanisms of a new class of composite coatings fabricated by embedding benzotriazole (BTA) laden nanotubes prior-functionalized with interfacial wrappings of chitosan hydrogel (CTSH) entrapping excess crosslinking agents (glutaraldehyde (GTRA) or epichlorohydrin (EPIH)) in epoxy (E44) matrix cured with polyamide . The modification led to an improvement in the barrier and physical properties of the composite coatings and introduced shape-memory self-repairing capabilities. Long-term impedance spectroscopy (EIS) complemented with the physical property tests was employed to interrogate the improved barrier properties. The coatings' microstructure and composition analyzed with SEM and EDS reveal the shape-memory self-repairing effect which was further characterized with overtime optical snapshots of samples exposed in a salt-spray chamber. The antibacterial functionality of the composite coatings against some marine bacteria ( Marinobacter aquaeolei and Marinobacter salsuginis ) was characterized using combined SEM and confocal laser scanning microscopy (CLSM). UV–visible spectrophotometry data reveal the pH-responsive release of the entrapped functional materials from the composite coatings. The experimental findings show that the new composite coatings exhibited intriguing triple-action protective functionalities and were more effective in protecting Q235 carbon steel exposed to 3.5 % NaCl compared to the conventional epoxy coating . This suggests that comparatively, the composite coatings have promising applications in structures that are exposed to sea environments.

Water shortage has been a serious issue for many years. Hydrate-based desalination (HBD) technology is a potential candidate for this solution. The present study investigates the use of Cyclopentane (CP) as a hydrate former for desalination through crystallization at low temperatures and atmospheric pressure. The primary objective of this work is to provide phase equilibrium data for CP hydrates (CPH) in the presence of novel salt systems, including NaBr, KBr, K2SO4, NaBr–KBr, NaCl–NaBr, KCl–KBr, Na2SO4–K2SO4, and CaCl2–MgCl2. Phase equilibrium temperatures were determined using both rapid and slow dissociation procedures. The van der Waals and Platteeuw-based Kihara (Kihara) approach, Hu-Lee-Sum (HLS) correlation, Standard Freezing Point Depression (SFPD) approach, and Activity-Based Occupancy Correlation (ABOC) were applied to model these new experimental data. The experimental results demonstrate that the differences between the quick and slow procedure data range from 0 °C to 1.2 °C. In addition, the increasing salt concentration enhances the inhibitory effect on hydrate formation. Furthermore, the influence of cations on the equilibrium temperature follows the decreasing order of Mg2+> Ca2+> Na+> K+. In terms of halide anions, Br−exhibits a stronger impact on equilibrium temperature compared to Cl−. The thermodynamic modeling results (for all four models) show good agreement with the experimental data with the average absolute deviation (AAD) of less than or equal to 0.79 °C. The ABOC approach proves to be the most effective among the four methods evaluated for accurately reproducing the equilibrium temperature of CPH, with AAD less than or equal to 0.38 °C.

In this study, combining roasting with steam cooking was proposed to reduce sodium chloride (NaCl) content during cooking operations. The NaCl reduction effects of roasting-steam cooking (RS), roasting (R), and water bath cooking (WB) on marinated salmon flesh samples with different cooking times (2, 4, 6 and 8 min) were evaluated. Results showed that the NaCl contents in the samples treated by RS and R were reduced by 22.44% and 15.59%, respectively. RS could also provide high overall acceptability without compromising the taste and flavour. FTIR analysis demonstrated that RS and R increased α-helix and β-sheet and slightly decreased β-turn in sample proteins as compared with WB, indicating that RS could achieve low denaturation and weak unfolding degree of protein structure due to protein conformation inhibited by the steam. Therefore, RS could serve as a novel method for reducing NaCl contents in cooked meat products.

In order to develop a process for the simultaneous production of furfural and easily hydrolyzable cellulose, the degradation of sugar cane bagasse in a single aqueous system and in a 2-methyltetrahydrofuran (MTHF)/aqueous AlCl3 biphasic system was studied. In single aqueous system, the influence of acid species (FeCl3, HCl, and AlCl3) on furfural production and cellulose degradation was investigated at 150 °C. FeCl3 and HCl promoted furfural production from hemicellulose but with severe cellulose degradation. AlCl3 decreased cellulose degradation with considerable furfural yield and high glucan content in solid residues. The role of NaCl in furfural production and cellulose decomposition was also investigated in the single aqueous system using different acids as catalysts. Addition of NaCl significantly promoted furfural yield but also accelerated cellulose decomposition when FeCl3 or HCl was used as catalyst. In the AlCl3-catalyzed system, NaCl had less influence on residue yield and its composition, although NaCl also promoted furfural production. The influence of MTHF on furfural yield, residue composition, and enzymatic hydrolysis of residue was also studied. Under the best conditions (0.45 g of bagasse, 9 mL of MTHF, 9 mL of water, 0.1 M AlCl3, 150 °C, 45 min, and 10 wt % NaCl), 58.6% furfural was obtained while more than 90% of cellulose remained in the residue. The organic phase was separated from the aqueous phase directly by decantation. After reuse of organic phase for 3 cycles, 11.5 g/L furfural was obtained. The catalyst-containing aqueous phase could be reused directly after decantation of the organic phase without loss of activity. The obtained residue was easy to hydrolyze and produced 89.3% glucose yield after 96-h enzymatic hydrolysis at low cellulase loading (30 FPU of cellulase/g glucan).

In this paper, effect of rare earth oxide nano-additives on the corrosion behavior of Fe-based hardfacing alloys was studied. The corrosive solutions were 3.5 wt.% NaCl + 0.01 mol/L HCl solution, 3.5 wt.% NaCl solution and 3.5 wt.% NaCl + 0.01 mol/L NaOH solution. The deep-etched microstructure of the hardfacing alloys was observed. The potentiodynamic polarization curves and electrochemical impedance spectra were used to study the corrosion behavior of the hardfacing alloys. The polarization test results showed that nano-additives shifted the corrosion potentials of the hardfacing alloys towards the noble direction in corrosive solutions. The values of the equivalent circuit elements for the impedance spectra of the hardfacing alloys indicated that nano-additives increased the corrosion resistance of the hardfacing alloys. When the content of nano-additives was 0.3 wt.%, the hardfacing alloy possessed the maximum charge transfer resistance in acid NaCl solution. The hardfacing alloy with 0.6 wt.% nano-additives had the maximum charge transfer resistance in near-neutral and alkaline NaCl solutions. The change in volume fraction of the primary and eutectic carbides and refinement of primary carbide influenced the corrosion behavior of the hardfacing alloys.

The long-term corrosion inhibition for AA5052 aluminum alloy was achieved by the hybrid inhibitor combined by rosemary extract (RSE) and zinc chloride (ZnCl 2 ) which could offer more than 30 days of protection for AA5052 Al alloy in a 0.05 M NaCl solution. The highest efficiency of ZnCl 2 , RSE, and hybrid inhibitor (ZR) reached 67.34 %, 88.41 % and 96.48 % at 2000 ppm, respectively. The excellent inhibition performance of the hybrid inhibitor was attributed to the synergism between RSE and ZnCl 2 . The electrochemical measurements show that the long-term inhibition performance is due to the combination of adsorption film and Zn oxide/hydroxide precipitated film.
