Abstract: Currently, the production-to-consumption food system is a multifaceted process that includes processing, handling and distribution, and allows to get food largely safe, tasty, nutritious, abundant, diverse, convenient, less costly and more accessible than ever. Along the path of food from producers to vendors until consumers, its quality can be altered, for instance, upon microbial and chemical contamination and unsuitable storage conditions. As a consequence, the offer by producers and vendors of tasty, fresh and safe foods to consumers is a crucial goal to preserve market sustainability on one side and people health on the other side. For these reasons, each step of this path must fulfil the requirements fixed by government authorities and referred to stringent standards and benchmarks to ensure food safety until use. For the assessment of optimal quality assurance of foods, manufacturers need cost-effective and rapid methods, preferably working on-line, performing measurements of the chemical, physical and microbiological properties of raw materials, transformed foods along the process streams and end products. The monitoring during food processing prevents expenses of either reworking or disposal of out-of-specification (low-quality) products. The recent advances in nanotechnology-based molecular sensing [1] have been addressed to develop novel sensors and sophisticated sensing systems to be potentially used in each step of the production-transportation-storage-processing-distribution food chain. The unique electric, optical and chemical properties of nanomaterials allow their employment, for example, in arrays of sensors and biosensors, electronic noses and tongues [2], test-strips, cantilevers, radio-frequency identification (RFID) tags, surface-enhanced Raman scattering (SERS) nanoprobes, chemical sensors embedded in packaging and naked-eye colorimetric sensors, to detect the presence of various adulterations in complex food matrices and to speed up the tests and improve the accuracy of food regulatory agencies. Nanomaterials such as metal, metal oxide and magnetic nanoparticles (NPs), carbon nanotubes (CNTs), graphene, MeOx/Me nanorods, quantum dots (QDs), nanowires and composite nanofibres are playing a noticeable role in designing sensors and sensing platforms with lower detection limits and improving the performances of conventional methods for food analyses. In food quality testing procedures and devices, nanomaterials provide several advantages, over conventional materials, such as ultra-sensitivity, selectivity, multiple targeting, portability, reproducible data processing, packaging conformability. In the present review, some remarkable achievements are discussed recently obtained in applications of nanotechnologies to food quality maintenance and monitoring, and the most promising results attained by using electrospun-based sensors are highlighted [3].
