Special Issue Information

Dear Colleagues,

A Intelligent Flavor Sensing System (IFSS), a kind of olfactory and gustatory simulation technology based on a rapid perception system and the pattern recognition method, can nondestructively detect the overall flavor profiles of foods in real time under atmospheric pressure. As the typical IFSS, electronic nose (e-nose), and electronic tongue (e-tongue) based on cross-sensitive sensor array were developed as artificial human olfactory and gustatory systems, both can describe the overall flavor characteristics of foods rather than being limited to feature compounds. Moreover, gas chromatography-ion mobility spectrometry (GC-IMS, also known as “Super E-nose”), nuclear magnetic resonance (NMR, also known as the “Magnetic Tongue”), electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS) are taken as IFSSs for the evaluation of the overall flavor quality of foods in real time. Moreover, such Intelligent Flavor Sensing Systems can be widely used for process monitoring, freshness and shelf-life evaluation, authenticity identification, quality assessment, etc.

This Special Issue will report recent advances in Intelligent Flavor Sensing Systems for addressing these challenges, including progress in sensor material development, achievements in intelligent signal processing algorithms and methods, novel measuring techniques, practical applications, etc.

This Special Issue, titled “Application of Intelligent Flavor Sensing System for the Quality Detection of Foods”, invites papers on topics including but is not limited to the following:

  • Fabrication of new-style flavor sensors;
  • Development of new-style Intelligent Flavor Sensing Systems;
  • Signal normalization, standardization, optimization, and baseline correction;
  • Chemometric approaches for feature extraction and data fusion;
  • Pattern recognition methods for classification and prediction.

BF3, volatile amines (VOAs), and biogenic amines (BAs) are the key indicators in chemical reaction catalysis and food quality monitoring. In this study, we present two types of fluorescent sensors, a hydrazone ligand (HL)-based fluorescent sensor for BF3 detection and a novel sensor array using six boron difluoride (BF2) hydrazone complexes (BFHs) for monitoring VOAs and BAs. Spectral research indicates that the interaction mechanism between the HLs and BF3 is based on intramolecular charge transfer (ICT). The HLs for the monitoring of BF3 showed good sensitivity, selectivity, and anti-interference and have the characteristics of a visible color change. Additionally, the HL probe demonstrates reversibility in the presence of triethylamine, making it a candidate for “ON-OFF-ON” mode sensing. BF3 detection can also be efficiently performed using test strips for convenient, air-based applications. The BFH sensor array successfully differentiates histamine from the other typical non-volatile BAs in solution; in comparison, the VOAs are analyzed through recognition patterns and statistical analysis. The array’s color changes enable the practical, on-site detection of shrimp spoilage, with principal component analysis distinguishing various ageing intervals. In summary, this sensor array demonstrates high selectivity for VOAs and BAs, with significant potential for application in real-world sample analysis. Full article
