This research investigates active packaging films made from polyvinyl alcohol (PVA) and nanocellulose fibers (NFC), incorporating silver nanoparticles (AgNPs) synthesized from Terminalia chebula extract, which possesses antibacterial and antifungal properties. The developed films were tested for their mechanical properties, microbial inhibition, and biodegradability. The results showed that the addition of AgNPs from Terminalia chebula enhanced product protection and effectively extended the shelf life of strawberries while being environmentally friendly.

This study aims to investigate the co-encapsulation technique of vitamin C and coenzyme Q10 within liposomes to enhance their stability and encapsulation efficiency and evaluate their antioxidant activity and release behavior under simulated gastrointestinal conditions. Liposomes were prepared using the High-Speed Homogenization Method, and their characteristics, including particle size, zeta potential, encapsulation efficiency, and antioxidant activity, were analyzed using DPPH, ABTS, and FRAP assays. The results demonstrated that co-encapsulation significantly improved the stability of vitamin C and coenzyme Q10 compared to single encapsulation. The liposomes exhibited high encapsulation efficiency and maintained strong antioxidant activity. The release profile under simulated gastrointestinal conditions also indicated a sustained and controlled release. These findings highlight the potential of the co-encapsulation technique in enhancing the efficacy of functional bioactive compounds, making it applicable to the food and nutraceutical industries.

Spent hens are laying hens that are over 18 months to 2 years old and no longer productive. The texture of spent hen meat is significantly tougher compared to broiler chickens, capons, and native chickens. Therefore, to increase the value of spent hens, a study was conducted to modify the texture of the meat by restructuring it with carrageenan and tenderizing it by marinating it in bromelain solution at different concentrations. The experiment found that restructuring with carrageenan and using bromelain enzyme resulted in a newly formed product and significantly improved the tenderness of the meat compared to chicken meat that was not treated with carrageenan and bromelain enzyme.

This thesis presents the development of an IoT system that integrates various communication standards to work together seamlessly. The Core Board serves as the IoT gateway, connecting LoRa, Wi-Fi, and BLE interfaces, and is powered by the STM32H563Zi microcontroller based on the ARM Cortex M33 architecture. The system is designed with slots to support additional communication standards and includes a web platform for data monitoring.
