Special Issue Information
Dear Colleagues,
Aim and Scope
The use of sensors and chemical analysis plays a vital role in ensuring food safety and quality throughout the food supply chain. These advanced technologies aim to detect harmful substances such as pathogens, toxins, pesticides, and allergens, while also monitoring food freshness and quality parameters. Additionally, they help ensure compliance with food safety regulations by providing rapid and accurate analysis of food products. The scope of these technologies extends from raw material screening to final product testing, covering various stages of food production, processing, and distribution. By integrating artificial intelligence (AI) for advanced data processing and analysis, these methods can offer improved pattern recognition, predictive insights, and decision-making support. By continuously assessing food safety and quality, these tools play a crucial part in safeguarding public health and maintaining consumer trust in food products.
Summary
Sensors and chemical analysis methods offer several advantages for food safety and quality assessment: they enable rapid detection, providing quick results compared to traditional methods; demonstrate versatility in detecting a wide range of chemical substances and microorganisms; offer high sensitivity for identifying even trace amounts of contaminants; allow real-time monitoring for the continuous assessment of food quality parameters; and provide portability, with some sensors designed for on-site, immediate testing. Chemical analysis techniques, including chromatography, spectrometry, titration, gas chromatography-mass spectrometry (GC-MS), gas chromatography-ion mobility spectrometry (GC-IMS), and high-performance liquid chromatography (HPLC), are widely used for detecting nutrients, contaminants, and additives in food products. Sensors, such as metal oxide sensors, surface acoustic wave sensors, and electrochemical sensors, are capable of detecting gases that indicate food spoilage or contamination. Advances in these technologies are driving the development of more reliable, efficient, and cost-effective tools, fostering their integration into smart food packaging and automated quality control systems, thereby enhancing food safety and reducing waste.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
