Summary: The study demonstrated that adding 5% nano-SiO2 improved the barrier properties of the composite film, while adding 7% nano-SiO2 significantly enhanced the mechanical properties of the film. Nano-SiO2 also increased the melting temperature of the composite film, and through spray drying encapsulation, the stability of walnut oil microcapsules was improved by incorporating nano-SiO2 into the wall material.

Summary: With the increasing awareness of ecological and environmental protection, the study aimed to explore a novel soy protein isolate (SPI) film functionalized with antioxidants from Xanthoceras sorbifolia husk (XSHE) as bio-based active packaging films. The characterization techniques revealed the hydrogen-bond interaction between SPI and XSHE, contributing to improved properties such as tensile strength, UV blocking, and water barrier. The introduction of XSHE further improved the antioxidant capacity of the films, making them promising for food packaging applications.

Summary: In this study, chitosan films were improved by incorporating nanofillers to enhance their mechanical properties, barriers, and antibacterial properties. The addition of lignin nanoparticles improved UV blocking property, while the inclusion of acylated soy protein isolate nanogel enhanced the sustained antibacterial property. The optimal composite film showed increased tensile strength and decreased oxygen barrier property compared to pure chitosan film, exhibiting higher antibacterial activity. However, the incorporation of nanofillers slightly reduced light transmission and increased surface roughness of the films.

Summary: Cinnamaldehyde was added to edible composite films made of soy protein isolate and egg white to develop active food packaging. The addition of CIN significantly improved antioxidant and antimicrobial activities, but reduced tensile strength and water vapor permeability of the films. The study demonstrates the potential of SPI/EW/CIN films as eco-friendly bioactive materials in food packaging.

Summary: The study evaluated the effects of incorporating carvacrol in soy protein isolate (SPI) films, showing that carvacrol can reduce resistance and rigidity of SPI films and increase their extensibility. Changes in protein secondary structure and release kinetics were observed, with glycerol promoting carvacrol release from the films. Films containing >= 2% carvacrol exhibited high antimicrobial activities against Listeria grayi in vapor phase, suggesting potential use in active packaging for food safety improvements.

Summary: This study found that incorporating cellulose nanocrystals (CNC) into soy protein isolate films can effectively improve the film properties, including tensile strength, barrier properties, and water resistance. The appropriate addition of CNC can promote the construction of a more homogeneous and compact film structure, while excessive addition may weaken the functional properties.

Summary: In this study, a bioinspired nanocomposite was developed by intercalating graphene oxide nanosheets into the soy protein isolate-glycerin matrix, resulting in enhanced mechanical properties and water resistance. After chemical reduction, the film exhibited significantly increased tensile strength and modulus. Moreover, the material maintained its original morphology and exhibited excellent interfacial interactions. Therefore, SPI-based materials can be widely used in applications such as food packaging, tissue engineering, and gene delivery.

Summary: Chitosan films with poor mechanical property, low water-resistance, and limited antimicrobial activity were improved by incorporating cinnamaldehyde-tannic acid-zinc acetate nano-particles (CTZA NPs) assembled from edible medicinal plant extracts. The composite films showed increased tensile strength, water contact angle, and reduced water sensitivity. Moreover, CTZA NPs enhanced UV adsorption, antibacterial, and antioxidant properties, while reducing water vapor permeability. The hydrophobic CTZA NPs facilitated ink deposition and allowed the films to be used for printing. These films with excellent antibacterial and antioxidant activities can be applied in food packaging.

Summary: The study focused on improving the mechanical properties and moisture barrier of oxidized corn starch (OS) film by incorporating soy protein isolate (SPI) at different ratios and pH values. The increase in SPI ratio and pH led to reduced moisture content and improved moisture barrier, as shown by lower water vapor permeability and higher contact angle. The blended films exhibited denser microstructures and smoother surfaces at higher pH values, suggesting interference with the intermolecular interaction of OS by SPI.

Summary: The aim of this research is to enhance the mechanical and water-resistance properties of soy protein isolate (SPI) biofilm. Modified nanocellulose with 3-aminopropyltriethoxysilane (APTES) was added to the SPI matrix with citric acid cross-linker. The results showed that the modified nanocellulose-incorporated film had better mechanical and thermal properties, as well as improved water resistance compared to the non-modified film. Additionally, the coating of citral essential oil onto the SPI nanocomposite film displayed antimicrobial properties.

Summary: The effects of microfluidization cycles on the physicochemical properties of SSE films were investigated. It was found that increasing the number of microfluidization cycles led to smaller particle sizes, increased protein adsorption on oil droplets, and more uniform structures of the SSE films. Moreover, the mechanical properties and surface hydrophobicity of the SSE films improved, while transparency and glass transition temperatures decreased.
