Special Issue Information

Dear Colleagues,

Food quality generally refers to the evaluation of foods through physical, chemical, or microbiological analysis. It is an aspect of food security that requires innovative methods to keep up with dynamic trends in the complex food chain matrix. On the other hand, it is necessary to explore different emerging technologies that can be used for disease detection and on-line monitoring. These technologies are based on detecting and analyzing chemical compounds in biological samples, such as breath, saliva, sweat, and urine.

The electronic tongue (e-tongue), the electronic nose (e-nose), near-infrared spectroscopy (NIRS), and gas chromatography–mass spectrometry (GC-MS) are advanced analytical approaches with high sensitivity that have been extensively applied in research and industry because of their advantages in rapid quantitative and qualitative food analysis. The e-tongue requires liquid or liquidized samples, but the e-nose, GC-MS, and NIRS offer noninvasive analytical advantages. The potential to measure more diverse food quality factors with these instruments is undoubtedly promising and continues to be unraveled by recent researchers. Keeping pace with developments in this scope is imperative for quality control of unprocessed, processed, and semi-processed foods from farm to fork.

The e-nose has recently been used in biomedical applications for diagnosing and monitoring diseases such as cancer, diabetes, kidney disease, and respiratory diseases. The e-tongue has also been used for the diagnosis and monitoring of diseases such as diabetes, kidney disease, and neurodegenerative diseases. These technologies have the potential to provide rapid, non-invasive, and accurate diagnoses, which could improve disease treatment and management.

This Special Issue invites original research papers and review articles that focus on the recent applications of the e-tongue, the e-nose, NIRS, and GC-MS, either as independent techniques or correlative methods with other analytical instruments and respective chemometrics for food quality and biomedical applications. This is an emerging frontier for increasing breakthroughs and solving challenges directly impacting the food industry and health sector.

This work consists of a study to detect prostate cancer using E-senses devices based on electronic tongue and electronic nose systems. Therefore, two groups of confirmed prostate cancer and control patients were invited to participate through urine and exhaled breath samples, where the control patients group was categorized as Benign Prostatic Hyperplasia, Prostatitis, and Healthy patients. Afterward, the samples were subsequently classified using Pattern Recognition and machine learning methods, where the results were compared through clinical history, obtaining a 92.9% success rate in the PCa and control samples’ classification accuracy by using eTongue and a 100% success rate of classification using eNose.
