Nowadays，It is difficult for the polysaccharide-starch system to meet demand of practical production owing to the poor gel properties. Therefore, aiming to further improve the practical application of polysaccharide-starch gel, the effects of gallic acid (GA) and heat moisture treatment (HMT) on the gel properties and microstructure of yam starch/chitosan (YS/CS) composite gels were investigated. Swell power (SP) results showed that GA and HMT treatment respectively reduced the SP of YS gel by 3.24 g/g and 6.03 g/g, given that GA and HMT decrease the rheology of the water phase inhibiting the entry of water into the swollen starch. In the pasting process, HMT reduced pasting viscosity of the HMT/YS system because only little amylose was leached in the medium for elevating its viscosity after HMT. The rheological properties suggested that high temperature treatment of HMT facilitated the disruption and disintegration of starch granules resulting dynamic modulus had a decline trend. The elastic properties of GA/YS gels were enhanced with the addition of GA, which could be supported by the thicken lamellar observed in its microstructure. In general, GA and HMT effectively alter the gel properties of YS/CS gel system, and facilitate its practical application in food industry.

In this study, we formulated a series of multifunctional hydrogels, namely Ga 3+ -GA-CMCS-Oin hydrogels (GGCO), leveraging Schiff base reactions and metal-polyphenol coordination. These GGCO hydrogels were synthesized using oxidized inulin (Oin) and gallic acid-modified carboxymethyl chitosan (GA-CMCS) as key bio-based components, and the crosslinking was achieved through Schiff base bonds between Oin’s aldehyde groups and GA-CMCS’s amino groups, eliminating the need for additional crosslinking agents. Moreover, the phenolic hydroxy groups on GA formed metal-polyphenol coordination bonds with Ga 3 ⁺, endowing the hydrogels with potent antibacterial properties and photothermal conversion capabilities. GGCO hydrogels demonstrated exceptional multifunctionality, including superior self-healing, strong adhesion, pH sensitivity, biodegradability, and antioxidant activity. Antibacterial assessments highlighted GGCO’s photothermal antibacterial efficacy, reaching a sterilization rate as high as 99.7%. In a mouse infectious wound model, GGCO hydrogels effectively eradicated bacteria, mitigated inflammatory responses, and accelerated wound healing. Histological analysis further underscored the potential of these multifunctional GGCO hydrogels for advanced wound care solutions.

A dual-functional TCCN-LaFeO₃ Z-scheme heterojunction is constructed for synchronous tetracycline degradation and gallic acid detection. • The composite achieves 95.27% tetracycline removal within 120 min and excellent reusability via Z-scheme charge transfer. • Sensitive and selective colorimetric detection of gallic acid is realized with a low detection limit of 0.32 μM. • The bifunctional material shows satisfactory practical performance in real water and pharmaceutical samples. TCCN-LaFeO 3 (TCCN refers to graphite carbon nitride modified by tetracyanoethylene) composite materials were successfully prepared using a simple hydrothermal method. The photocatalytic degradation performance of the composite was investigated using tetracycline (TC) as the target pollutant. The results indicate that under conditions of a catalyst loading of 40 mg, an initial TC concentration of 20 mg/L, a solution pH of 7, under visible-light irradiation from a 250 W xenon lamp with a 400 nm cut-off filter (400–800 nm), the tetracycline degradation rate reached 95.27% after 120 min of reaction. The degradation process followed a first-order kinetic model with a rate constant of 0.0243 min −1 . Furthermore, the TC degradation rate remained above 85% after five reuse cycles, demonstrating excellent stability. Additionally, when this composite was used for the colorimetric detection of gallic acid (GA), a good linear relationship (R 2 = 0.993) was observed between the GA concentration and the absorbance of the reaction system at 652 nm over the concentration range of 0–110 μM, with a detection limit as low as 0.32 μM. Interference and spiked recovery experiments using actual samples demonstrated that this method exhibits good selectivity and accuracy, with recovery rates ranging from 98.3% to 101.4%. The TCCN-LaFeO 3 composite prepared in this study holds significant application value in the fields of tetracycline degradation in water and the rapid detection of gallic acid.

Chlorogenic acid (CA), gallic acid (GA), and resveratrol (RES) were added to a gelatin (GEL)-chitosan (CHI)-glycerol (GLY) edible coating, and their effects on the coating of fresh beef preservation were investigated. The results revealed that CA had the most significant improvement effect on fresh beef preservation. The combination of GEL-CHI-GLY-CA preserved the color of the beef better and delayed the increase of the total volatile base nitrogen, even though its total phenolic content decreased at a faster rate during beef preservation. GA also improved the preservation effect as on the 12th day of storage, the beef samples treated with GEL-CHI-GLY-GA had the lowest thiobarbituric acid reactive substances (0.76 mg Malondialdehyde (MDA)/kg) and total viable count (6.0 log cfu/g). On the whole, though RES showed an improvement on beef preservation, the improvement was not as good as the other two polyphenols. After 12 days of storage, the beef samples treated with GEL-CHI-GLY-RES had a higher pH value (6.25) than the other two polyphenol treatmed groups. Overall, the three polyphenol-added combinations increased the shelf life of beef by approximately 3–6 days compared to the control group (treated GEL-CHI-GLY with distilled water).Keywords:fresh beef;edible coating;polyphenols;meat quality

We proposed an efficient and scalable ultrasound-assisted approach for the synthesis of functionally integrated nanohybrid of silicon dioxide (SiO 2 ) nanoparticles and multi-walled carbon nanotubes with graphitization and carboxylation (GCMCN), which was employed to modify the glassy carbon electrode (GCE) for the fabrication of GCMCN@SiO 2 /GCE sensor. Graphitization of GCMCN contributed to the reduction of defect density and enhancement of electrical conductivity , and carboxylation of GCMCN improved the dispersion degree of carbon nanomaterial due to the hydrophilicity of carboxyl groups. SiO 2 nanoparticles possessed abundant binding active sites for target analytes due to the surface hydroxyl groups or silanol groups, which were beneficial for the enrichment of gallic acid (GA) molecules. For the functionally integrated GCMCN@SiO 2 nanocomposite, the interconnected conductive networks of GCMCN presented more efficient charge transport channels, which recompensed the non-conductive property of SiO 2 nanoparticles. Based on the functional collaboration of GCMCN and SiO 2 nanoparticles, the fabricated GCMCN@SiO 2 /GCE sensor presented good GA detection property (GA concentration: 0.01–15 μM, LOD value: 1.99 nM). The proposed sensor exhibited acceptable repeatability, reproducibility, and selectivity. Moreover, the good practicability performance could be effectuated at the GCMCN@SiO 2 /GCE sensor for the quantitative analysis of GA in black tea and green tea samples.

In this study, zein-gallic acid covalent complex prepared by alkali treatment was utilized as an emulsifier to stabilize cinnamon essential oil (CEO) Pickering emulsion, and the chitosan-based (CZGE) films loaded with CEO Pickering emulsion were prepared by blending. The influences of different contents of CEO Pickering emulsion on the physical properties and biological activities of CZGE films were investigated. The results showed that Pickering emulsion had good compatibility with chitosan matrix and enhanced the interaction between film-forming matrix polymer. In addition, incorporating with CEO Pickering emulsion (15 %, v /v) significantly improved the mechanical and barrier properties of the films, and also enhanced the light transmittance and thermal stability of the films. Furthermore, the loading of emulsion also improved the antioxidant activities of the films and led to the formation of high antimicrobial property against food pathogens, and the slow-release behavior of CEO could effectively extend the biological activity of the films. These results suggested that Pickering emulsion has potential as a loading system and a plasticizer in active packaging, and the feasibility of CZGE film in food packaging.

Injectable self-healing hydrogels with antioxidation are required in wound dressings. Because oxidative damage caused by excessive reactive oxygen species (ROS) is a common issue associated with chronic non-healing wounds. Here, collagen (COL) - and hyaluronic acid (HA)-based hydrogel with antioxidant and injectable self-healing mediated with gallic acid (GA) and dopamine (DA) offers unique advantages for wound repair. The hydrogel is constructed by COL-grafted GA (CG), HA-grafted DA (HD) and γ-poly(glutamic acid) (γ–PGA) coupled with 3-aminophenylboric acid (APBA) via the dynamic boronic ester bonds. Rheological measurements and direct visual observation demonstrated the hydrogel's desirable injectability and self-healing properties. Additionally, the hydrogel exhibits tissue adhesion properties. Biocompatibility and cell migration tests showed that the hydrogel promotes cell proliferation and migration. In vitro, antioxidant and intracellular free radical scavenging assays confirmed the hydrogel's antioxidant property and ability to scavenge excess ROS. In vivo wound healing studies have demonstrated that hydrogel can promote angiogenesis , inhibit inflammation, and promote collagen fiber deposition to accelerate wound healing.

The antioxidant efficiency of gallic acid (GA) and its alkyl esters including methyl gallate (MG), ethyl gallate (EG), propyl gallate (PG), butyl gallate (BG), octyl gallate (OG), lauryl gallate (LG), hexadecyl gallate (HG), and octadecyl gallate (SG) in oyster tissue during hot-air drying process was investigated. Results indicated that GA and its alkyl esters all could effectively retard lipid oxidation in oyster tissue according to peroxide value (POV), thiobarbituric acid reactive substances (TBARS) and free radical intensity. The antioxidant effects increased with the alkyl chain length until OG, thereafter, it gradually decreased. The POV of the OG treated oysters post 10 h of drying was 66.26, 68.90, 77.86, 92.61, 89.45, 70.79, 68.96 and 62.70%, respectively, of those treated by GA, MG, EG, PG, BG, LG, HG and SG. The corresponding values for TBARS were 68.72, 76.59, 77.88, 84.32, 86.23, 68.31, 81.24, 77.36%, while 41.19, 58.62, 62.83, 64.49, 69.60, 61.44, 60.05 and 72.61% for free radical intensity. Pearson correlation analysis showed a positive correlation between the antioxidant effects and the concentrations of the polyphenol compounds in oyster tissue. This report will provide the basic data for selection of suitable antioxidants to improve the oxidation stability of seafood during thermal processing.

Hydrogels have emerged as fascinating material for various applications in the chemical, biomedical, and energy fields. Generally, their poor self-healing performance, mechanical properties , and bioactivity limit the application of hydrogels in bioelectronics. Herein, a self-healable, injectable, stretchable, self-adhesive, biocompatible, and conductive poly( N -vinylpyrrolidone)/gallic acid (PVP/GA) composite hydrogel was fabricated via hydrogen bonding between the tertiary amide groups in PVP and hydroxyl groups in GA. The PVP/GA composite hydrogel possesses excellent self-healing properties after damage. The composite hydrogel is highly stretchable and can adhere to human skin to detect physiological activity signals precisely according to the resistance signals. The composite hydrogel has good biocompatibility with living organisms. It is envisioned that multifunctional PVP/GA composite hydrogels can be applied to the electronic skins, wearable biosensors, and body movements monitoring equipment.

A simple and green colorimetric sensing assay strategy for highly efficient determination of melamine has been fabricated, which is based on the redox reaction of gallic acid with Ag+. Monodispersed Ag nanoparticles (AgNPs) were obtained using gallic acid as a reducing and stabilizing agent. However, the aggregate behavior of AgNPs was observed, while the melamine was present in the reaction medium. As a result, the color of the solution changed from vivid yellow to brown, and the density of the color was quantitatively correlated with the melamine concentration. The aggregation of AgNPs could be attributable to the formation of hydrogen bonds between melamine and gallic acid. The designed sensor exhibited a good detection limit of 0.099 μM (0.012 ppm), which was much lower than the safety limit in China (1.0 ppm) and EU (2.0 ppm). Additionally, the sensing assay displayed good selectivity toward melamine over other coexisting substances. Consequently, the proposed colorimetric sensor was successfully used for the determination of melamine detection in raw milk samples.

In this paper, a method for the enzymatic modification of pectin, in which gallic acid (GA) and propyl gallate (PG) were grafted onto pectin molecules in an aqueous/organic two-phase system catalyzed by lipase, was proposed. The potential reaction mechanism was explored through UV–Vis, FTIR and 1 H NMR spectroscopic methods and density functional theory. Results suggested that the lipase played a dual role during the modification by catalyzing the hydrolysis of methyl ester bonds of pectin in the aqueous phase and the esterification between the 4-OH of GA and PG and the –COOH of pectin in the organic phase. Moreover, the effects of GA and PG on the antioxidant and the antibacterial activities of pectin were evaluated, and results showed that the antioxidant and the antibacterial activities of modified pectin were better than those of native pectin. The effect of modified pectin on the quality of fresh bass ( Lateolabrax maculatus ) was further studied. Results suggested that, compared to control group, the total viable count , histamine level , malondialdehyde content and acid value of bass fillets treated with modified pectin were significantly reduced, whereas the sensory score was significantly increased.

In this study, chitosan (CS) was grafted with phenolic acids including gallic acid (GA-g-CS) and caffeic acid (CA-g-CS) through carbodiimide coupling. The conjugates were further developed into films by casting and were characterized in terms of appearance, structure, and mechanical and barrier properties, as well as antioxidant and antimicrobial activities; the purpose was to evaluate their potential application in food packaging. The results showed that the CA-g-CS film exhibited the highest tensile strength (10.67 ± 0.47 MPa) and elongation at break and had desirable barrier properties against water vapour (0.70 ± 0.02 g mm/m 2 h kPa) and oxygen (37.72 ± 0.23 meq/kg). In addition, both the GA-g-CS and CA-g-CS films displayed higher antioxidant activity than the CS films, while CA-g-CS also exhibited a significantly stronger ( p < 0.05) inhibitory effect on Bacillus subtilis (G + ) and Staphylococcus aureus (G + ). These findings will contribute to a theoretical basis for the development of the CA-g-CS film into food packaging.
