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: 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: This research evaluates the influence of plasticizer type and content on the performance of TPS blown films. It is found that replacing glycerol with larger-sized plasticizers such as xylitol or sorbitol can improve the film properties, enhancing tensile strength, stiffness, and barrier properties, with potential applications in food and pharmaceutical packaging.

Summary: Synergized multi-plasticizers were developed for starch-based edible film used in food packaging. Water, glycerol, and sorbitol were used to demonstrate the synergistic effect of combining different plasticizers. The characteristics of tensile properties were studied under different humidity conditions and for different storage times. The results showed that water, glycerol, and sorbitol have their own advantages as plasticizers, but their function can be enhanced when used together.

Summary: The research found that PTSEs with longer chains can improve some properties of starch, but the defect in chain growth of PTSEs has a negative impact on its effectiveness. In starch films, PTSEs resulted in more but weaker H-bonds. Longer chains help improve mechanical properties, but reduce the mechanical stability of composite films.

Summary: This study fabricated thermoplastic wheat starch-sugarcane bagasse biocomposites using the melt mixing method and evaluated the effect of sorbitol:glycerol weight ratio and bagasse concentration on their physicomechanical properties. The results showed that increasing the weight ratio of sorbitol to glycerol and the concentration of bagasse significantly increased the tensile strength and modulus, while decreasing the elongation at break and equilibrium moisture content. Lower weight ratios of sorbitol to glycerol and lower bagasse concentrations led to higher initial moisture absorption rates and greater moisture absorption capacity. TGA analysis revealed improved thermal stability of the biocomposites with increased sorbitol:glycerol weight ratio and bagasse concentration. FTIR spectrum indicated an increase in hydrogen and polar bonds in the biocomposites compared to pure starch.

Summary: This study used oligomers based on glycerol citrates to reduce plasticizer migration in potato-based TPS/PVA blends, while maintaining high swelling degree and providing high mechanical performance. This approach, using melt-mixing technique, represents a first step towards industrial scalability.

Summary: The study found that the addition of different types and concentrations of plasticizers significantly affects the appearance, physical properties, and mechanical properties of corn starch films. Specifically, sorbitol-plasticized films exhibit excellent mechanical properties, while glycerol and sorbitol/glycerol plasticized films have higher moisture content and water absorption.

Summary: The aim of this research is to study the destructuration of three native starches and wheat flour in mixtures of water and choline chloride. The study shows that choline chloride impacts the gelatinization of starch and that the exotherm observed is not only related to depolymerization of the starch, but also to a crystalline rearrangement stage coexisting with this phenomenon.

Summary: The efficiency of potato starch plasticization using two deep eutectic solvents (DESs) based on choline chloride (CC) and glycerol (G) or urea (U) has been evaluated. Both DESs exhibited solubility towards starch, but CCU showed significantly higher solvent power than CCG. The XRD result indicated that both DESs were able to penetrate the starch crystal regions and form stable hydrogen bonds with the hydroxylic groups of the polysaccharide. The viscosity and thermal stability of the starch material depended on the DES content, with a decrease in viscosity and thermal stability observed with increasing DES content. The gelatinization temperature was strongly affected by the type of DES, occurring at a lower temperature in CCU compared to CCG. The plasticization efficiency was tested using modulated DSC, and it was found that CCG had higher plasticizing efficiency compared to CCU.

Summary: Sustainability has increased the interest in using renewable resources, and starch has been widely used to produce bioplastics. This research studied the effect of different plasticizers on cassava starch bioplastics produced through injection molding. The results showed that a mixture of glycerol and water as plasticizers resulted in hardened materials that softened significantly at both low and high humidity. Bioplastics made from cassava starch and 30% glycerol exhibited low water uptake and uniform structure, making them suitable for food packaging applications.

Summary: This study investigated the effects of plasticizer type and concentration on the characteristics of bionanocomposite films, revealing that increasing plasticizer content led to increased film thickness and moisture content, but decreased density. Different types of plasticizers did not significantly affect the antibacterial activity of the films.

Summary: This study developed and optimized starch microstructures for encapsulating vitamin B3 using the electrospinning process. The addition of plasticizers such as poly(ethylene oxide) (PEO) and glycerol improved the plasticity and stability of the starch solution during electrospinning. The microstructures with 12% w/w starch exhibited the highest encapsulation efficiency and antioxidant activity.
