Special Issue Information

Dear Colleagues,

Over the past decade, the design of smart packaging has updated traditional packaging designs by performing added functions, showing promising applications in various fields. Particularly, it has been applied to promote the sustainability of food systems by extending the shelf life of food products, cutting food loss caused by safety concerns, and reducing food waste derived from the predetermined expiration date. Given the advantages of smart packaging over inert packaging materials, its global market is rapidly expanding and is projected to reach USD 38 billion by 2030.

Smart packaging is an umbrella term that encompasses active packaging and intelligent packaging. Active packaging is able to release active substances into the packaged items or adsorb substances from the packaging headspace, while intelligent packaging is integrated with an internal or external indicator capable of monitoring the real-time conditions of the packaged products or their surrounding environment. Within this Special Issue, we will address the novel additives and materials used for smart packaging, which can potentially be used for industrial applications, including but not limited to: (1) Natural or synthetic additives in active packaging, especially nanomaterials, which are antimicrobial, antioxidant, biodegradable, possess good compatibility in commercial packaging systems, or act as fillers in composite materials for the improvement of mechanical and barrier properties; (2) Inexpensive, robust indicators for use in intelligent packaging that are enabled by novel technologies, such as nanotechnology,  3D printing, biomimetics, artificial intelligence, and the Internet of Things.

We are pleased to invite you to submit a manuscript for this Special Issue. Original full-length research papers, short communications, and review articles are all welcome.

Control of food spoilage is a critical concern in the current world scenario, not only to ensure the quality and safety of food but also to avoid the generation of food waste. This paper evaluates a dual-sensor strategy using six different pH indicators stamped on cardboard for the detection of spoilage in three different foods: beef, salmon, and strawberries. After function validation and formulation optimizations in the laboratory, the halochromic sensors methyl orange and bromocresol purple 2% (w/v) were stamped on cardboard and, in contact with the previously mentioned foods, were able to produce an easily perceptible signal for spoilage by changing color. Additionally, when it comes to mechanical characterization the inks showed high abrasion (>100 cycles) and adhesion resistance (>91%). Full article
