Tea tree oil (TTEO) is a natural active agent, but less stable. In this research, a covalent organic frameworks, CTB, is prepared, and used to load TTEO (CTB@TTEO), and then CTB@TTEO as the filler is used to prepare starch-based active packaging films for storage blueberries. The results show that CTB@TTEO could increase the mechanical strength, gas barrier, antioxidant activity, and bacteriostatic activity of the thermoplastic starch film. The starch-based active packaging film with 2 wt% CTB@TTEO possesses the superior preservation effect on blueberry fruits. It is due to that the starch-based active packaging film with 2 wt% CTB@TTEO has the most compact structure, and displays outstanding bacteriostatic activity for Staphylococcus aureus and Escherichia coli. In addition, CTB@TTEO exhibits a pH-sensitive release characteristics. The release dynamics of TTEO in CTB@TTEO conform Avrami models. Consequently, the starch-based active packaging with 2 wt% CTB@TTEO has a promising application potential for fruit preservation.

The aim of this study was to screen lactic acid bacteria (LAB) suitable for starch-based fermentation from traditional fermented shredded potatoes (TFSP). Analysis of the microbial diversity by 16S rDNA sequencing in TFSP revealed that LAB were a genus with high relative abundance of the bacteria population. Thirty LAB strains were isolated and purified from TFSP.

Filamentous fungi encode a wide repertoire of antifungal proteins (AFPs) with potential applications for the control of fungal diseases. In this study, we report the simultaneous production of three distinct AFPs by a natural soil isolate of Aspergillus fischeri, including the previously uncharacterized class C protein AfAfpC. AfAfpC was the most abundantly secreted AFP, followed by NFAP2 and, to a lesser extent, NFAP, when grown in YPD medium, whereas AfAfpC was also detected in minimal medium and starch-based formulations.

Flexible hydrogel sensors demonstrate emerging applications, such as wearable electronics, soft robots, and humidity smart devices, but their further application is limited due to their single-responsive behavior and unstable, low-sensitivity signal output. This study develops a dual-responsive starch-based conductive hydrogel via a facile "one-pot" strategy, achieving mechanically robust pressure sensing and ultra-sensitive humidity detection. The starch-Poly (2,3-dihydrothieno-1,4-dioxin)-poly (styrenesulfonate) (PEDOT:PSS)-glutaraldehyde (SPG) hydrogel integrates physical entanglement and covalent crosslinking to form a porous dual-network architecture, exhibiting high compressive fracture stress (266 kPa), and stable electromechanical sensitivity (ΔI/I, ~2.

Hazardous ultraviolet (UV) radiation found in sunlight can seep into food packaging and cause unfavorable physicochemical changes in food items. This study aimed to develop starch-based polymeric biofilms with UV-blocking capability by incorporating CeUiO-66 metal-organic framework nanoparticles (Ce66 NPs). These nanoparticles were synthesized a solvothermal method using formic acid as a modulator.
