Summary: The addition of active agents into PLA significantly affects its optical properties, polymer chain reordering, thermal properties, functionality, and compostability. The dispersion degree and crystallinity changes of AAs from specific processing techniques also impact the mechanical and barrier performance of PLA. Furthermore, the release kinetics of AAs from PLA can be modified by the different physical properties of the films resulting from specific processing techniques.

Summary: This study focuses on designing cost-effective and sustainable edible packaging films with multifunctional activities. By incorporating silk sericin, chitosan, and carbon dots, the bio-nanocomposite films demonstrated enhanced flexibility, antimicrobial, and antioxidant properties compared to films made solely of silk sericin. The components were well dispersed within the film matrix network, and the presence of carbon dots allowed the films to exhibit blue fluorescent emission, which could be used as an anticounterfeit label. Furthermore, the fruit-litchi test confirmed the effectiveness of the bio-nanocomposite film in preserving nutritional components. Overall, this study provides insights into the use of silk sericin and carbon dots for the preparation of environmentally friendly edible food packaging films and their application in effective fruit preservation.

Summary: The global demand for safe, effective, and natural products is increasing as consumers become more concerned about personal and environmental health. Propolis, a traditional medicinal product with various health benefits, has a worldwide reputation. However, its broader industrial uses have been limited due to low productivity and high chemical heterogeneity. This study investigated the antimicrobial and antioxidant properties of propolis blends from different localities and years and found that the blends maintained or even enhanced these activities. Additionally, the chemical composition differences in the original propolis samples were diluted in the mixtures. These results highlight the potential of propolis and suggest that mixing different samples can standardize propolis while increasing its availability and value.

Summary: Cellulose from different bamboo species was converted to cellulose nanocrystals (CNCs) using a chemical-mechanical method. The CNCs showed varying diameters and crystallinity depending on the species used. The CNCs were incorporated into cassava starch-based films, resulting in improved water solubility and reduced water vapor permeability. The films with 0.4 g of CNCs exhibited the highest tensile strength and can be used as biodegradable packaging material.

Summary: This study compares sugarcane straw fiber (SSF) prepared by chemical pulping (CP) and steam explosion (STE) methods. The results show that STE has a higher yield and tensile strength, but lower elongation and compression strength compared to CP. The SSF trays made by STE have less swelling, longer wetting time, and higher water contact angle compared to CP trays. The STE method also results in smaller fiber size, higher residual lignin content, and lower crystallinity index. Although CP is preferred for high flexibility and fiber purity, STE shows superior physical and mechanical properties and can be a green pulping technique for durable biobased trays.

Summary: The effect of sodium hydroxide concentrations on the morphology, mechanical properties, and water barrier properties of carboxymethyl rice starch films was investigated. Increasing NaOH concentrations resulted in higher degree of substitution of CMSr powders, leading to changes in morphology. The water solubility, elongation at break, and water vapor permeability of the films increased as NaOH concentrations increased, while the water contact angle, melting temperature, and tensile strength decreased.
