Summary: Thermoplastic cassava starch films were synthesized using different ratios of native cassava starch, glycerol, and cardanol-based plasticizers. The concentration of cardanol-based co-plasticizers greatly influenced the mechanical properties, with significant increases in modulus and tensile strength, as well as a decrease in elongation. The moisture content and thermal resistance were also affected by the co-plasticizer content.

Summary: Recently, there has been an increasing global awareness of the negative environmental impacts of single-use plastics due to their nonbiodegradability and tendency to end up in the ocean. Thermoplastic starch (TPS) is a viable alternative material for single-use products due to its high biodegradability, low cost, and nontoxicity. However, TPS has moisture sensitivity and poor mechanical properties and processability. Blending TPS with biodegradable polyesters, such as PBAT, can enhance its practical applications.

Summary: Using mannitol in combination with sorbitol as a plasticizer can improve the plasticizing performance of starch films. The ratio of mannitol to sorbitol at 60:40 showed the smallest surface roughness and the lowest degree of freedom of water molecules, effectively delaying the retrogradation of starch films.

Summary: Starch is a key polysaccharide used in biopolymer film synthesis due to its renewable source, abundance, cost effectiveness, and excellent film making properties. Starch-based films are flexible and strong, but can be made more hydrophobic by incorporating copolymers or fillers to improve mechanical properties such as tensile strength and elongation at break. Additionally, the composition of starch, plasticizers, and operating conditions also play a significant role in determining the physico-chemical properties of starch-based films.

Summary: The study investigated the effects of different degrees of substitution of hydroxypropyl cassava starch with agar and maltodextrin on the microstructure and properties of edible packaging films. The findings suggested that higher DS starch and agar improved extrusion processability, while maltodextrin increased plasticization and reduced network strength, affecting the overall performance of the films. The combination of agar and maltodextrin also influenced the water vapor and oxygen permeability of the films, showing potential for enhancing the properties of the packaging materials.

Summary: Blending of plasticized hydroxypropyl cassava thermoplastic starch (TPS) with polybutylene adipate terephthalate (PBAT) via blown-film extrusion was studied. Higher DS values were found to increase film clarity and glossy surface, reduce crystallinity, improve hydrophilicity, mechanical properties and compatibility between PBAT and TPS. Modified DS in hydroxypropyl starch efficiently improved clarity, mechanical and barrier properties of bioplastic packaging.

Summary: By using saccharides with different structures and molecular weights as plasticizers for starch-based materials, the plasticity of the starch-based materials can be effectively enhanced. Saccharides that can stably remain in the starch matrix increase the stability of moisture in starch, while potentially disrupting the crystalline range of the starch.

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.
