Special Issue Information

Dear Colleagues,

Ensuring food safety is an ongoing global challenge, particularly as the food industry faces growing demands for higher production, extended shelf life, and stringent contamination control. The utilization of nanomaterials and nanotechnology offers novel solutions to enhance the safety of the food supply chain. These solutions facilitate the expedient identification and surveillance of pathogens, contaminants, and quality control during food production and distribution. This Special Issue aims to highlight recent advancements in the use of nanotechnology in food safety, showcasing the application of nanosensors, nanobiosensors, nanocarriers, and nanostructured materials to enhance food safety detection.

 We invite original research articles and reviews on topics such as nanomaterial-based sensors for the detection of pathogens, toxins, allergens, chemical contaminants, and adulterants in food products. Contributions exploring nano-based food packaging technologies, such as antimicrobial nanocoatings and smart packaging with integrated sensing capabilities, are also highly encouraged. Furthermore, the integration of nanotechnology with food safety management systems, such as real-time monitoring of critical control points and the use of nanomaterials for contaminant removal or degradation, will be featured. Manuscripts should present clear, concise, and well-supported findings, with a focus on practical applications and novel methodologies that will drive advancements in food safety practices worldwide.

Climate change increases microbial contamination risks in food, highlighting the need for real-time biosensors. However, food residues often interfere with detection signals, limiting the direct application.

Climate change increases microbial contamination risks in food, highlighting the need for real-time biosensors. However, food residues often interfere with detection signals, limiting the direct application. An integrated system of filter-assisted sample preparation (FASP) and an immunoassay-based colorimetric biosensor offers the rapid and simple on-site detection of foodborne pathogens in complex food matrices. The accuracy and stability of biosensor analysis were ensured via filter-assisted preprocessing, which separated food residues from bacteria. The system was applied to various food matrices, including vegetables, meats, and cheese brine, using samples spiked at contamination levels ranging from 102 to 103 CFU per 25 g, thereby demonstrating broad applicability. Bacterial recovery varied by food matrix, with vegetables showing a 1-log reduction and meats, melon, and cheese brine showing a 2-log reduction relative to the initial inoculum. A detection limit of 101 CFU/mL was achieved for Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes in the final preprocessed sample solutions. Sample preparation took under 3 min, and detection was completed within 2 h under stationary conditions. This approach enables rapid pathogen detection in various food matrices without the need for special reading devices, contributing to food safety as a real-time, rapid-response food biosensor.

The global food industry is facing growing pressure to enhance food safety, extend shelf life, minimize waste, and adopt environmentally sustainable packaging solution. Nanotechnology offers innovative ways to meet these demands by enabling the creation of smart and sustainable food packaging systems. Due to their unique properties, nanomaterials can significantly enhance the functional performance of packaging by boosting mechanical strength, barrier efficiency, antimicrobial activity, and responsiveness to environmental stimuli. This review provides a comprehensive overview of nanomaterials used as smart and sustainable food packaging, focusing on their role in active and intelligent packaging systems. By integrating nanomaterials like metal and metal oxide nanoparticles, carbon-based nanostructures, and nano-biopolymers, packaging can now perform real-time sensing, spoilage detection, and traceability. These systems improve food quality management and supply chain transparency while supporting global sustainability goals. The review also discusses potential risks related to nanomaterials’ migration, environmental impact, and consumer safety, as well as the current regulatory landscape and limitations in industrial scalability. Emphasis is placed on the importance of standardized safety assessments and eco-friendly design to support responsible innovation. Overall, nano-enabled smart packaging represents a promising strategy for advancing food safety and sustainability. Future developments will require collaboration across disciplines and robust regulatory frameworks to ensure the safe and practical application of nanotechnology in food systems. Full article
