Summary: This study investigates the effect of different fractions of kraft lignin on the structure and performance of thermoplastic starch (TPS) matrix during photooxidative degradation. Kraft lignin from Eucalyptus urograndis wood was fractionated in ethyl acetate (EtOAc), and the fractions were added to TPS matrix films. The samples were exposed to UV-C light for accelerated aging, and their structural, thermal, morphological, and mechanical properties were analyzed. It was found that the fraction of lignin with higher phenolic hydroxyl group content provided the best photoprotection and stabilizing effect on TPS matrix.

Summary: A novel waste-based plasticizer derived from modified used palm oil (mUPO) has been developed and used as a plasticizer to improve the properties of non-glutinous thermoplastic starch foam. The addition of mUPO has a direct effect on mechanical and thermal properties, increasing impact strength and reducing glass transition temperature. It also reduces shrinkage and moisture absorption in the starch foam. The utilization of mUPO as a waste-based material shows promise as a green alternative plasticizer for starch components, especially in foam applications.

Summary: Oil resistant thermoplastic elastomers were prepared by blending mung bean thermoplastic starch with rubbers and sericin as a compatibilizer. The addition of sericin and epoxidized NR improved the mechanical properties, elastic recovery, and oil swelling resistance of the blends. FTIR analysis confirmed a reaction between sericin and ENR, which enhanced the compatibility and oil resistance of the blends.

Summary: The research found partial compatibility of cassava starch and corn starch with polycaprolactone (PCL) in the blends, along with changes in crystal quality of PCL and displacement of absorption bands in the infrared spectrum. The crystallinity of PCL in the presence of cassava and corn starch was higher than that of pure PCL, suggesting improved nucleation at the interface. Based on these findings, the blends are suitable for manufacturing short-term use products using conventional thermoplastic processing methods.

Summary: Utilizing starch as a renewable filler blended with PBAT can create cost-effective and high-performance biodegradable materials. The thermal processing properties of starch can be manipulated by its plasticized behavior. In this study, epoxidized soybean oil and glycerol were used as plasticizers for starch and integrated with PBAT, resulting in a starch-based biodegradable blend film with balanced properties.

Summary: Functional food emulsions enriched in health-promoting nutrients, such as buriti oil, have been studied for their effects on cardiometabolic health. This study investigates the colloid transformations of whey-stabilized buriti oil-in-water emulsions during simulated digestion. It is found that the oil phase transforms into highly ordered structures during simulated intestinal digestion under compromised bile conditions, and the digestion process can be modulated by adding vitamin E to the oil.

Summary: The study demonstrates that maleinized hemp seed oil (MHO) acts as a plasticizer and compatibilizer for polylactic acid (PLA) and thermoplastic starch (TPS) blends, providing a dual effect on these partially miscible biopolymers. The addition of MHO significantly improves the ductile properties of the blend, while maintaining thermal properties without significant decrease, and does not compromise the biodegradability of the blend.

Summary: The effects of sisal fiber content and its surface treatment on the thermal degradation behavior and structures of thermoplastic cassava starch composites were investigated. It was found that increasing fiber content can enhance the thermal decomposition temperature, and sisal fiber treated with sodium hydroxide showed better thermal stability.

Summary: This study investigated the potential application of various sterilization methods for microorganism inactivation on the thermoplastic starch blend surface. Results showed that e-beam radiation was the only method to effectively remove bacterial microflora, while UV radiation had the least impact on the blend's properties. Additionally, irradiation was found to accelerate the decomposition of the material during enzymatic degradation studies.

Summary: In this study, sugar palm crystalline nanocellulose (SPCNC)-reinforced thermoplastic sugar palm starch (TPS) was blended with poly(lactic acid) (PLA) to balance the individual polymer limitations and prioritize biodegradation feature. The results showed that incorporating SPCNC into TPS led to a significant reduction in water uptake of the blend in all mediums and a slight increase in soil degradation rate. However, PLA40TPS60 and PLA60TPS40 exhibited flammable properties.

Summary: The current study evaluated the characteristics of thermoplastic cassava starch (TPCS) containing various levels of palm wax, showing that incorporating palm wax significantly improves the mechanical properties of starch-based thermoplastics and enhances their moisture resistance. The samples also exhibited intermolecular interactions and hydrogen bonds between TPCS and palm wax. Overall, TPCS blended with palm wax demonstrates potential as a biodegradable material with enhanced mechanical and moisture resistance properties.

Summary: Potato thermoplastic starch (TPS) containing different types of halloysite (HNT), including pure HNT, glycerol-modified HNT (G-HNT), and polyester plasticizer-modified HNT (PP-HNT), were prepared by melt-extrusion. The interactions between TPS and halloysites were characterized by FTIR, SEM, and DMTA. The addition of HNT and G-HNT improved the TPS's thermal stability and water resistance, while also increasing its stiffness and mechanical properties. Pure HNT showed the best thermal stability, but PP-HNT exhibited better thermal stability than G-HNT. TPS/HNT showed the formation of a new crystalline phase, indicated by an additional beta-relaxation peak.

Summary: In this study, composite films composed of PVK and different ferrites were prepared using sonication and drop-casting technique, and their optical and morphological properties were investigated. The introduction of ferrites resulted in increased optical absorption, reduced band gap, broadened emission spectra, and shortened excited state lifetimes of PVK, indicating the creation of donor/acceptor states in the bandgap. Although SEM images showed aggregated ferrites, most of them were well dispersed in the PVK matrix.
