Developing safe, non-toxic and high-efficiency coating materials for food preservation has become a critical research focus in the field of food packaging. In this study, a catechaldehyde-cross-linked gelatin/sodium hyaluronate (GHAP) composite coating was engineered to improve the antibacterial and antioxidant functionalities of gelatin. By optimizing the cross-linking ratio, a GHAP4 film with superior overall properties was obtained. Fourier transform infrared (FTIR) analysis confirmed that the aldehyde groups of catechaldehyde participated in cross-linking reactions with the amino groups of the gelatin–sodium hyaluronate matrix. The GHAP4 film exhibited excellent antioxidant activity, achieving a DPPH radical scavenging rate of 96.8%, and showed strong antibacterial effects against Escherichia coli and Staphylococcus aureus . Furthermore, cytotoxicity tests suggested that all concentrations of GHAP4 solution exhibited cell viability exceeding 100%. Zebrafish toxicity tests showed that the GHAP film had no significant toxicity to zebrafish, with no deformities or deaths observed. Preservation experiments using strawberries as a model sample showed that the GHAP4 coating effectively slowed down changes in colour, titratable acidity and soluble solid content, extending the shelf life from 4 to 8 days. This study provides new ideas and a theoretical basis for the application of natural polymer-based functional coatings in fruit and vegetable preservation.

In this study, the cellulose acetate phthalate (CAP) film loaded with tannic acid (TA) was prepared in the work using the electrospinning method. The addition of TA increased both the conductivity and the viscosity of the electrospinning solution, which resulted in a higher average fibre diameter (1.14 ± 0.30 to 1.32 ± 0.32 μm). The electrospun films exhibited antibacterial activity, with the highest inhibition zone diameter values of 8.3 mm against Escherichia coli and 8.5 mm against Staphylococcus aureus , as well as antioxidant activity with a maximum free radical scavenging rate at 41%. The combined benefits of TA-loaded electrospun CAP film and vacuum skin packaging on the quality of minced beef were investigated. It has been found that the microbial, physical and chemical deterioration of the minced beef was effectively retarded; hence, it extended its shelf life by an extra 2 days. In conclusion, the TA-loaded electrospun CAP film is highly effective in preserving the quality of minced beef using vacuum skin packaging.

An isostatic aroma permeation measurement system was developed using a customized permeation cup and dynamic SPME-GC-FID coupled to a flow-cell unit. The limit of quantitation (LOQ) of the method ranged from 0.012 to 0.054 mg/m 3 with a PDMS-coated SPME Arrow, with typical linearity from 5 to 600 mg/m 3 . The system's repeatability on a polyethylene terephthalate (PET) film was between 8.7% and 25.0% (%RSD, n = 4). The results were verified using headspace GC–MS and thermal desorption GC–MS, with relative average deviation (%RAD) ranging from 6.0% to 20.7%. The aroma barrier performance of six film samples, including PET, biaxially oriented polypropylene (BOPP) and vacuum metalized polyethylene (PET//VMPE), was compared using this method with a mixture of five model aroma compounds, such as 2-methyl pyrazine, 2-heptanone and benzaldehyde. This method provides a sensitive, automated and low-cost solution for evaluating the aroma barrier performance of polymer films, with potential applications in the packaging industry.

The objective of this research was to develop and analyse a chitosan- Tremella fuciformis polysaccharide (CS-TFP) edible film using chitosan (CS) and Tremella fuciformis polysaccharide (TFP) as the primary raw materials. The findings revealed significant improvements in the thickness, solubility, opacity, mechanical properties and barrier properties (water vapour and oxygen permeability) of the chitosan film upon the addition of TFP, but water content and hydrophobicity were reduced. Moreover, TFP addition markedly enhanced the antibacterial and antioxidant activities of the chitosan films. Structural analysis of the CS films and CS-TFP edible films indicated that the formation of hydrogen bonds and high compatibility between CS and TFP. Specifically, TFP increased crystallinity, reduced roughness and improved the compactness of the edible film. This increase in compactness was directly linked to enhanced physical properties, whereas increased crystallinity contributed to better thermal stability. Furthermore, the application of CS-TFP-3 edible films in chicken preservation proved that they could significantly delay the deterioration of chicken. Findings in this study suggested that CS-TFP edible film as a bioactive packaging material showed great potential to preserve chicken meat and extend the shelf life.

In this study, the effectiveness of enzymatic treatments on cellulose for improving the properties of moulded pulp products was investigated. Three treatment systems were evaluated: laccase (L) alone, an L/lauryl gallate (LG) binary system, and a L/LG/chitosan (CTS) ternary system. The optimal conditions for the L/LG/CTS system were determined as 40.0 U·g −1 L, 1.0 wt.% LG, 1.0 wt.% CTS, 3.0 wt.% pulp consistency, a reaction temperature of 50°C, and a reaction time of 4 h. Compared with untreated moulded pulp products, which exhibited poor barrier properties (static water contact angle: 0°, Cobb 60 : 141.21 ± 5.24 g·m −2 , Kit test: 0/12) and limited mechanical performance (tightness: 1.04 ± 0.03 g·cm −3 , tensile index: 29.86 ± 1.32 N·m·g −1 , bursting index: 0.85 ± 0.07 kPa·m 2 ·g −1 , tear index: 5.72 ± 0.28 mN·m 2 ·g −1 , folding resistance: 82 ± 2), the L/LG/CTS-treated products demonstrated notable improvements. Specifically, hydrophobic/oleophobic properties improved markedly (static water contact angle: 104.5° ± 2.9°, Cobb 60 : 14.83 ± 0.71 g·m −2 , Kit test: 8/12) and mechanical strength increased substantially (tightness: 1.18 ± 0.03 g·cm −3 , tensile index: 34.78 ± 0.96 N·m·g −1 , bursting index: 1.88 ± 0.09 kPa·m 2 ·g −1 , tear index: 6.23 ± 0.30 mN·m 2 ·g −1 , folding resistance: 93 ± 5). SEM analysis revealed changes in fibre arrangement and improved fibre network cohesion in treated samples. These findings indicate that the L/LG/CTS ternary system is a highly effective and sustainable strategy for enhancing both barrier and mechanical properties of moulded pulp products, positioning them as a promising alternative to petroleum-based plastics for food packaging applications. Although the L/LG/CTS system uses biodegradable components, future investigations are required to comprehensively evaluate the biodegradability of the final treated products.

In order to inhibit the growth and reproduction of microorganisms in the exudate of fresh aquatic products during storage. Absorbent paper, absorbent cotton and nylon mesh were used as the substrates, three types of clay minerals (diatomite, columnar diatomite and bentonite) were used as the water absorbing materials and a new type of unidirectional water-conducting preservation pads was prepared. The physicochemical properties of water absorbing materials and preservation properties of pads for Lateolabrax japonicas fillets were measured. The results show that all three kinds of clay have good water absorption properties, and bentonite exhibits the highest water retention properties because of metal oxide. After absorbing water, the surface holes of diatomite and columnar diatomite particles are blocked, while the volume of bentonite particles increases. Bentonite absorbs water slowly but retains water best and can absorb 10.31 times its own mass of water. Preservation study shows that water absorption preservation pads can effectively absorb the exudate of fish fillets and slow down the deterioration of fish fillet quality. Bentonite preservation pad shows the best effective and extends the shelf life of L. japonicas fillets from 6 to 9.3 days. This research can provide the technical support for the application of preservation pads carrying clay minerals in the field of fresh aquatic products.

This study is aimed at fabricating composite films by cross-linking polyvinyl alcohol (PVA) and dialdehyde cellulose (DAC) in varying ratios using citric acid as a catalyst. The acetal formation between the two components was studied using FTIR. Characterizations of the physiochemical properties revealed that increasing the DAC ratio of the composite film improved the hydrophobicity, tensile strength and barrier properties (water vapour, UV and oxygen) of the films while reducing elongation at break (flexibility), swelling and solubility of the film in water. When the DAC ratio was elevated to 50%, the tensile strength was enhanced to 98 MPa. In comparison, flexibility diminished to 29%, the solubility of the film reduced to 10% and water vapour permeability was lower by two orders of magnitude than that of the control PVA film. The peroxide value of linoleic acid decreased from 21.2% ± 7.6 (packed with PVA film) to 9.9% ± 0.9 (packed with 50% DAC composite film) after 15 days. Furthermore, the composite films demonstrated effective absorption of UV radiation, with the order of effectiveness being UV-C > UV-B > UV-A radiation. No significant difference in biodegradability was detected in the composite films with an increase in DAC ratio during indoor soil burial tests for 30 days. This study implies that the composite film could serve as an alternative sustainable packaging option, especially when transparency and high oxygen barrier properties are desired.

A pH-sensitive protein fibre membrane was prepared using alizarin (ALI), curcumin (CUR), gelatin, zein and cinnamaldehyde as raw materials, by electrospinning technology. The membrane was developed to detect food deterioration and extend shelf life. It was observed that the addition of CUR significantly enhanced the antioxidant and barrier properties of the membrane. The fibre membrane was responsive to pH with minimal colour alteration in response to humidity (from 20% to 80% relative humidity) and demonstrated excellent reusability along with a low detection limit for ammonia gas. Moreover, it was capable of monitoring low concentrations of bacteria in the headspace. To assess the efficacy of the membrane, a freshness monitoring and preservation study was carried out on pork stored at 4°C for 5 days. The fibre membrane not only prolonged the shelf life of meat but also allowed real-time monitoring of its freshness. The results highlight the potential application of the prepared nanofibres in the simultaneous monitoring and preservation of meat freshness.

A functional edible film containing Pickering emulsion (PE) loaded with oregano essential oil (OEO) was developed. The sustained release of OEO in muffins significantly delayed muffin decay at 25°C ( p < 0.05). According to the influence of oxygen permeability, antibacterial activity and mechanical properties of the active film, the optimum preparation conditions of PE were determined by orthogonal experiment. Peroxide values (POVs), total viable count (TVC) and yeast and mould count (YMC) were significantly lower compared with the blank group. On Day 6, the POV in the experimental group was 63% that of the blank group. TVC and YMC were 3.20 and 1.86 lg CFU/g on Day 9, respectively (TVC ≤ 1500 CFU/g; YMC ≤ 100 CFU/g), extending muffins shelf life to 6–7 days in practical preservation at 25°C. Thus, the edible PE loaded with OEO film provided sustained release, effectively slowing muffin quality deterioration and extending shelf life, making it a promising choice for future high-fat food packaging.

Smart packaging systems for real-time visual monitoring of food freshness play a crucial role in food safety. However, the intelligent packaging film is prepared by solution casting and extrusion moulding, the low efficacy limited the application. In this study, a pH colorimetric indicator film based on gelatin, anthocyanin and diatomite was fabricated via the industrial method of melt extrusion. The film exhibited good mechanical properties as well as excellent water resistance and antioxidant properties. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD) indicated that the fish gelatin (FG) interaction with anthocyanin/diatomite ( AD ) reduced the crystallinity and influenced the microstructure and mechanical properties of the thin film. The film exhibited high sensitivity to volatile amines with visible colour changes. When used to monitor the freshness of Litopenaeus vannamei from day 0 to 10 , the colour of the film shifted from purplish-red to brownish-yellow. Pearson correlation analysis indicated that the colour changes on films are closely related to the variations in TVB-N ( r = 0.98, p < 0.001) and pH ( r = 0.93, p < 0.01) values of L. vannamei . Therefore, the film can be utilized to monitor the freshness of L. vannamei and holds significant potential for large-scale industrial production.

Studies have shown that fluoridated reagents for oil and water resistance are harmful to the human bodies and the environment. Consequently, the developments of nontoxic, environmentally friendly, fluorine-free and degradable materials have received increasing attentions. Here, we introduce a novel method for fabricating a hydrophobic and oleophobic paper-based packaging material through the application of chitosan/carnauba wax emulsions. These emulsions were prepared via high-shear homogenization, blending melted carnauba wax with chitosan in acetic acid aqueous solutions. The stable chitosan/carnauba wax emulsion with particle size of 430 nm was prepared at the chitosan concentration of 1.5 wt%, the carnauba wax concentration of 8 wt% and temperature of 85 °C. After 10 g/m 2 of chitosan/carnauba wax emulsion was applied to the paper surface, the oil and water resistance of the paper was significantly improved. The experimental results of kit rating value, oil contact angle, Cobb 60 value and water contact angle were 9.5 ± 0.6, 86.6 ± 2.1°, 8.90 ± 1.62 g/m 2 and 123.5 ± 2.6°, respectively. The application of chitosan/carnauba wax emulsion coating on papers provided a significantly lower water vapour transmission rate (WVTR, 78.45 ± 18.92 g/m 2 ·24 h) and oxygen transmission rate (OTR, 94.26 ± 20.21 g/m 2 ·24 h) as compared to the original paper, which met the needs of strawberry packaging.

The development of sustainable and economical active food packaging remains a critical challenge for enhancing food quality and safety. This study presents an innovative strategy by utilising rice bran, an abundant agricultural waste product, to synthesise rice bran–derived bacterial cellulose (RBC) as a high-value matrix for active food packaging. This matrix was reinforced with zeolitic imidazolate framework-8 (ZIF-8) to fabricate multifunctional nanocomposite films. Structural analyses confirmed the successful integration of ZIF-8 into the RBC matrix via hydrogen bonding without disrupting its inherent crystalline lattice. The incorporation of ZIF-8 significantly improved the physical and functional characteristics of the packaging. Specifically, the optimal formulation (0.2% ZIF-8) enhanced tensile strength to 42.72 MPa and improved barrier properties against water vapour and oxygen. Notably, the film loaded with 0.1% ZIF-8 exhibited remarkable antibacterial efficacy, achieving a 99.41% inhibition rate against Escherichia coli . During chilled pork preservation trials, the nanocomposite films effectively suppressed microbial proliferation, delayed lipid oxidation and minimised the accumulation of volatile spoilage compounds. These synergistic effects successfully extended the shelf life of the pork by 6 days, demonstrating the film's superior capacity to extend food shelf life and ensure microbiological safety. This work highlights the promising potential of valorising RBC as a sustainable and highly efficient platform for advanced active food packaging.
