Abstract
Food packaging combined with active and intelligent properties plays an essential role in minimizing food waste and guaranteeing food quality. Herein, we developed a colorimetric and control-released dual-responsive nanofiber membrane (GF-AE-LI) with gelatin/fucoidan (GA/FU, i.e., GF) as matrix, aloe-emodin (AE) as indicator and limonene (LI) as antibacterial entity by electrospinning. The results exhibited that an appropriate combination of GA and FU based on the electrostatic interaction was conducive to constructing a carrier of GF in response to an alkaline atmosphere. The AE and LI were encapsulated in GF nanofibers with high efficiency and well-kept structure. Moreover, the membrane was capable of pH-controlled release of LI by a non-Fickian diffusion mechanism and strong antibacterial effects against Staphylococcus aureus and Escherichia coli. Furthermore, the membrane can effectively extend the shelf life of chicken breast meat by 2 d, and its pH-colorimetric changes were highly correlated with the spoilage indices (Pearson′s r = 0.9554), demonstrating the potential of GF-AE-LI toward simultaneously freshness monitoring and preservation of food.
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.
