Summary: The study found that using dielectric barrier discharge (DBD) plasma can enhance the strength and stiffness of corn starch-based films, reduce their hydrophilicity and water solubility, and have no significant effects on water vapor permeability (WVP). After 20 minutes of treatment, higher hydrophobicity, strength, and stiffness were observed in the films.

Summary: The hydrophobicity of corn starch films was improved by adding a new type of covalently formed, oxidized debranched starch/chitosan nanoparticles (SC-NPs). SC-NPs were obtained by a Schiff-base crosslinking reaction between the aldehyde group of dialdehyde debranched starch and the amino group of chitosan. The films reinforced with 3% SC-NPs showed greater water contact angles and improved barrier properties compared to pure starch films.

Summary: Edible films and coatings are potential methods for preserving fresh food. Starch is commonly used for film and coating production due to its low cost and wide availability. However, additives are often needed to overcome the limitations of starch-based films. This review focuses on the effects of additives on the properties of starch-based films and coatings, and their compliance with the requirements for edible and biodegradable food packaging. The use of additives enhances the barrier properties and bioactivity of the films, and also improves their shelf stability.

Summary: A novel antibacterial indicator film was developed by incorporating tangerine peel essential oil (TEO) Pickering emulsion stabilized by ultrasonic and esterified modified starch (UDSt) with corn starch, and purple corncob anthocyanin (PCA) for monitoring pork freshness. The film exhibited color changes at different pH and displayed excellent bacteriostatic activity against E. coli and S. aureus due to the loaded TEO. Additionally, the film had good light-blocking ability and free radical scavenging capacity, and the color change of the film could effectively indicate pork quality.

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: Starch, a renewable resource, is being extensively studied as a potential substitute for conventional polymers. This study focuses on modifying starch polymers through cross-linking, using tartaric, oxalic, and citric acids as cross-linking agents. Various tests were conducted to evaluate the properties of starch film samples. The results indicate that citric acid exhibits the highest cross-linking capability, possibly due to the presence of an extra carboxyl functional group. The number of carbonyl functional groups has a greater influence on cross-linking than the number of hydroxyl functional groups. Consequently, citric acid cross-linked starch outperforms other types of cross-linked starch and thermoplastic starch in terms of water resistance, tensile strength, and dimensional stability.

Summary: To effectively improve the antibacterial and physical properties of corn starch/chitosan films, starch/chitosan/polyethyleneimine (PEI) blend films crosslinked by citric acid were prepared. It was found that the addition of 3.75% PEI improved the tensile strength and elongation at break, but decreased the thermal stability. Incorporation of citric acid significantly enhanced the tensile strength and thermal stability of the films. Strong interactions were observed among citric acid, PEI, and starch-chitosan. All films showed inhibitory effects on E. coli and S. aureus, with the film containing 3.75% PEI and 5.0% citric acid having the best overall properties.

Summary: The study identified and quantified structures in the fine and coarse fiber fractions that retain starch, with protein matrix contributing to 54% of total starch retention. Confocal microscopy showed differences in starch granules placement in different regions of the endosperm. Protein disruption is likely to lead to the largest increase in starch extraction.

Summary: A low-cost and environmentally friendly method of synthesizing highly transparent and low-viscosity starch solution is investigated in this study. The corn starch is irradiated with an electron beam and treated with DMP which leads to the generation of hydrophilic structures and the destruction of surface morphology. Both irradiation and DMP treatment increase thermal-stability, transparency, and viscosity-stability, while decreasing coagulation, viscosity, and gelatinization temperature. Irradiation is more efficient in starch modification, with a dose of 4-10 kGy being effective. DMP treatment can modify starch, but its efficiency depends on the dose. A combination of low-dose irradiation and moderate DMP treatment can produce highly transparent, low-viscosity, and viscosity-stable starch solution, which may have potential applications in the food or textile industry.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
