Abstract

This study focuses on developing a tough, biodegradable film made from soy protein isolate (SPI) and carboxymethyl chitosan (CMCS), enhanced with titanium dioxide nanotube arrays (TNTAs). The main objective was to improve the hydrophobicity, mechanical strength, and thermal stability of SPI/CMCS films by incorporating TNTAs, making them suitable for food packaging, particularly in preserving high-moisture fruits like blueberries. The TNTAs were synthesized using anodic oxidation and integrated into the SPI/CMCS matrix through a solution-casting method. The resulting films exhibited enhanced mechanical properties, including higher tensile strength and better water resistance, without compromising biodegradability. Additionally, the SPI/CMCS/TNTAs composite films effectively maintain blueberry quality and extend their shelf life. These results suggest that SPI/CMCS/TNTAs films are promising candidates for sustainable and effective food packaging applications.

期刊介绍： Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
