Electronic nose devices stand out as pioneering innovations in contemporary technological research, addressing the arduous challenge of replicating the complex sense of smell found in humans. Currently, sensor instruments find application in a variety of fields, including environmental, (bio)medical, food, pharmaceutical, and materials production. Particularly the latter, has seen a significant increase in the adoption of technological tools to assess food quality, gradually supplanting human panelists and thus reshaping the entire quality control paradigm in the sector. This process is happening even more rapidly in the world of wine, where olfactory sensory analysis has always played a central role in attributing certain qualities to a wine. In this review, conducted using sources such as PubMed, Science Direct, and Web of Science, we examined papers published between January 2015 and January 2024. The aim was to explore prevailing trends in the use of human panels and sensory tools (such as the E-nose) in the wine industry. The focus was on the evaluation of wine quality attributes by paying specific attention to geographical origin, sensory defects, and monitoring of production trends. Analyzed results show that the application of E-nose-type sensors performs satisfactorily in that trajectory. Nevertheless, the integration of this type of analysis with more classical methods, such as the trained sensory panel test and with the application of destructive instrument volatile compound (VOC) detection (e.g., gas chromatography), still seems necessary to better explore and investigate the aromatic characteristics of wines.

This paper presents a comprehensive investigation to increase the gas sensing capability of pure tin oxide (SnO2) film coatings while ensuring non-contamination. The SnO2 thin-film coatings deposited on glass substrates were processed by homogeneous precipitation and sol–gel dip coating methods. Various characterization techniques, including X-ray diffraction, ultraviolet–visible spectroscopy (UV–Vis), and scanning electron microscopy were used to analyze the structural, optical, and morphological properties of the coatings. The prepared SnO2 coatings were tested using separately two different gases, carbon monoxide (CO) and propane (C3H8), to assess their gas sensing capabilities. The results show a significant influence of the multilayer coating of SnO2 on the sensing performance. Remarkably, the SnO2 sample with three layers exhibited a high sensitivity. By enhancing the gas sensing capabilities of tin oxide films through the dip coating technique, this study contributes to the advancement of gas sensing technologies.
