Special Issue Information

Dear Colleagues,

The food industry is undergoing a transformative shift with the emergence of novel smart packaging technologies, which aim to address pressing challenges in food safety, quality, and sustainability. This Special Issue, “Novel Smart Packaging in Foods”, explores groundbreaking advancements in intelligent and functional packaging systems that integrate sensors, bioactive materials, and data-driven solutions. These innovations not only extend shelf life and monitor food conditions in real time but also reduce waste and enhance consumer trust. By bridging disciplines such as materials science, biotechnology, and artificial intelligence, smart packaging is redefining how we preserve, track, and interact with food products. This collection of research articles and reviews highlights the potential of these technologies to create a more efficient and sustainable food supply chain. Through this Special Issue, we aim to foster collaboration and inspire future innovations in the dynamic field of smart packaging.

Dr. Xiaodong Zhai

Abstract
A ratiometric fluorescent film with high gas sensitivity and stability was developed using electrospinning technology for monitoring food spoilage. 5(6)-Carboxyfluorescein (5(6)-FAM) was used as the indicator, combined with the internal reference Rhodamine B (RHB), to establish a composite ratiometric fluorescent probe (FAM@RHB).

A ratiometric fluorescent film with high gas sensitivity and stability was developed using electrospinning technology for monitoring food spoilage. 5(6)-Carboxyfluorescein (5(6)-FAM) was used as the indicator, combined with the internal reference Rhodamine B (RHB), to establish a composite ratiometric fluorescent probe (FAM@RHB). The hydrophobic fluorescent films were fabricated by incorporating FAM@RHB probes into polyvinylidene fluoride (PVDF) at varying molar ratios through electrospinning. The FR-2 film with a 2:8 ratio of 5(6)-FAM to RHB exhibited the best performance, demonstrating excellent hydrophobicity with a water contact angle (WCA) of 113.45° and good color stability, with a ΔE value of 2.05 after 14 days of storage at 4 °C. Gas sensitivity tests indicated that FR-2 exhibited a limit of detection (LOD) of 0.54 μM for trimethylamine (TMA). In the application of monitoring the freshness of pork and beef at 4 °C, the fluorescence color of the FR-2 film significantly changed from orange–yellow to green, enabling the visual monitoring of meat freshness. Hence, this study provides a new approach for intelligent food packaging. Full article
