Summary: This paper introduces the potential of deep eutectic solvents (DES) as plasticizers for chitosan film in food packaging. Films based on chitosan and DES consisting of choline chloride (ChCl) and organic acids were studied for their structural, mechanical, thermal, contact angle, optical, antioxidant, and antibacterial properties. The addition of ChCl and acetylsalicylic acid resulted in films with optimal mechanical characteristics, reduced water contact angles, decreased decomposition temperature, strong UV shielding, and antioxidant properties. Films containing ChCl, acetylsalicylic acid, malonic acid, and lactic acid showed excellent antibacterial properties against Escherichia coli and Staphylococcus aureus.

Summary: Ultrasonication-assisted Fenton-system (US-Fenton) was used to synthesize chitosan-ferulic acid conjugates, and the effect of different ultrasonication times on the conjugates was investigated. The conjugate obtained after 1 minute of ultrasonication (FUS1) showed the highest grafting ratio and had improved structural and functional properties compared to the Fenton-grafted method. The FUS1 conjugate also exhibited strong antioxidant and antibacterial activities. A film made from FUS1 showed decreased viscosity, improved barrier properties, and increased water solubility and tensile strength compared to a chitosan film.

Summary: There is a high demand for multifunctional and sustainable packaging materials as alternatives to petroleum-based polymers. Soybean polysaccharides (SPS) show great potential as sustainable packaging materials due to their remarkable antioxidation and film-formation properties. However, their poor water resistance and mechanical properties have limited their further application. In this study, we developed an asymmetric multifunctional packaging film inspired by the Janus properties of lotus leaf. By incorporating SPS-stabilized silver nanoparticles with gelatin and wax, we were able to enhance the mechanical properties and water tolerance of the film, while also creating hierarchical micro-/ nano-structures on one side of the film resembling the natural front lotus leaf. This Janus film demonstrated outstanding water resistance, as well as excellent antibacterial activity, antioxidation properties, and UV-blocking performance. It has been successfully applied in food packaging, showing its potential as a sustainable high-performance solution.

Summary: Gelatin films crosslinked with dialdehyde quince seed gum (Gel/DAQSG) were prepared with different blending ratios by solution casting technique. The addition of DAQSG into the matrix of Gel films led to the chemical crosslinking between the amine groups of Gel and aldehyde groups of DAQSG. With the increase of DAQSG content, the number of crosslinked networks increased, causing the structure of Gel/DAQSG films to become denser and more compact. The Gel/DAQSG film with a ratio of 1:2 exhibited better water solubility, water vapor permeability, and tensile stress compared to pure Gel film. Additionally, the optimal film containing apple peel extract (APE) displayed high antioxidant activity and improved antibacterial activities against E. coli and S. aureus.

Summary: Commercial personal protective equipment (PPE) is unable to effectively inactivate microbes in the intercepted droplets/aerosols, making used PPE a potential source of cross-contamination. By incorporating oxidase-like catalysts into PPE, it becomes possible to inactivate bacteria in the intercepted droplets/aerosols without any external stimuli. This approach is applicable to different types of PPE and provides a feasible global solution for preventing the spread of infectious diseases.

Summary: The study found that natural antioxidants from sugarcane, tomato and orange by-products can help improve the shelf life of beef patties by reducing oxidative deterioration and delaying microbial growth. Additionally, high oxygen modified atmosphere packaging showed inhibitory effects on color and microbial growth in meat products, but did not improve oxidative stability of lipids and proteins.

Summary: Inorganic nanoparticles and natural antioxidant compounds as emerging trends in the food industry have shown potential in active food packaging applications. By incorporating them into biobased and biodegradable matrices, such as polysaccharides and proteins, these substances offer significant antimicrobial, antioxidant, UV blocking, oxygen scavenging, and water vapor permeability effects with low environmental impact. However, there are concerns about the migration and toxicological potential of metal NPs in food contact packaging.

Summary: About one-third of the world's food is lost and wasted each year, with perishable products like fruits and vegetables accounting for the largest percentage of food waste due to their short shelf life. This study introduces a biomimetic strategy using PLLA or chitosan porous microspheres in a shellac membrane to regulate gas permeability and selectivity, showing exceptional preservation performance on different fruits and potential for other applications. The materials demonstrate excellent properties such as antioxidant, antimicrobial, water-resistant, and reusability by controlling gas permeability and selectivity, making them promising for food preservation and controlled atmosphere applications.

Summary: In this study, pH-sensitive gelatin-based films were developed using response surface methodology with red cabbage extract and zinc oxide nanoparticles. Oxidized sucrose (OS) served as a cross-linker to compensate for gelatin solubility, leading to decreased solubility in films with higher OS levels. The combination of ZnONPs and OS enhanced antioxidant activity, with the optimum treatment including 0.043% ZnONPs and 11.45% OS to improve film strength and decrease flexibility. Antimicrobial activity was higher against Staphylococcus aureus than Escherichia coli, and the color of the optimum film changed from reddish-purple to blue-green between pH 3-12, providing innovative and intelligent packaging material.
