Special Issue Information

Dear Colleagues,

Nanotechnology has emerged as a key player in enhancing food safety and improving agricultural productivity. It holds great potential for quality, safety testing and enhancing food defense mechanisms. Food spoilage can be inhibited, microorganisms removed, and microbial cells prevented from adhering to food surfaces through the formation of novel nanoscale compositions with altered physicochemical properties, thus promoting food safety and safeguarding the health of consumers.

With this Special Issue, we hope to explore the application of nanotechnology in food safety by utilizing the latest advances in the related fields of nanosensors/nanofabrication technologies/nano-filtration membranes/nano-catalytic technologies in order to promote the relationship between food quality and safety and human dietary health. This Special Issue aims to contribute to quality and safety in the food industry by promoting interdisciplinary discussions and exchanges.

We invite experts and scholars from various backgrounds to share their original research articles, reviews, and short communications in the field of nanotechnology on applications, challenges, and the future of safety in the food industry.

Extensive use of pesticides in agricultural production has been causing serious health threats to humans and animals. Among them, phorate is a highly toxic organophosphorus insecticide that has been widely used in planting. Due to its harmful effects on human and animal health, it has been restricted for use in many countries. Analytical methods for the rapid and sensitive detection of phorate residues in agricultural products are urgently needed. In this study, a new method was developed by combining surface-enhanced Raman spectroscopy (SERS) and immunochromatography assay (ICA). Hybrid magnetic Fe3O4@Au@DTNB-Ab nanoprobes were prepared by modifying and growing Au nanoseeds on an Fe3O4 core. SERS activity of the nanoprobe was optimized by adjusting the concentration of the Au precursor. A rapid and sensitive assay was established by replacing the traditional colloidal gold-based ICA with hybrid SERS nanoprobes for SERS-ICA. After optimizing parameters including coating antibody concentrations and the composition and pH of the buffer solution, the limit of detection (LOD) for phorate could reach 1 ng/mL, with a linear range of 5~100 ng/mL. This LOD is remarkably lower than the maximum residue limit in vegetables and fruits set by the Chinese government. The feasibility of this method was further examined by conducting a spiking test with celery as the real sample. The result demonstrated that this method could serve as a promising platform for rapid and sensitive detection of phorate in agricultural products. Full article

Reducing fruit and vegetable waste and maintaining quality has become challenging for everyone. Nanotechnology is a new and intriguing technology that is currently being implemented in fruit and vegetable preservation. Silver nanomaterials provide superior antibacterial qualities, biodegradability, and biocompatibility, which expands their potential applications in fruit and vegetable preservation. Silver nanomaterials include silver nanocomposites and Ag-MOF, of which silver nanocomposites are mainly composed of silver nanoparticles. Notably, not all kinds of silver nanoparticles utilized in the preservation of fruits and vegetables are thoroughly described. Therefore, the synthesis, mechanism of action, and advancements in research on silver nanocomposites for fruit and vegetable preservation were discussed in this study. Full article
