Biogenic amines detection in food: Emerging trends in electrochemical sensors
Abstract
Amines are ubiquitous in living organisms and play essential roles in various physiological functions, including neurotransmission, hormonal regulation, cell signalling, and metabolism. In daily life, amines are found in cosmetics, pharmaceuticals, and foods. However, biogenic amines, formed through amino acid decarboxylation during food degradation, present a significant health risk, especially when combined with nitrites and nitrates in foods. Therefore, stringent control measures are essential. Thus, the development of user-friendly sensor devices for on-site monitoring of these molecules is a crucial area of research, because limited portable and simple options for amine detection and quantification are currently available. Electrochemical sensors offer an attractive solution for reliable and sensitive on-site measurements. With these sensors it is possible to carry out measurements, without complex sample processing. This review provides an overview of advancements in electrochemical sensors for detecting and quantifying various amines, highlighting the potential of different sensor configurations, sensing elements, and underlying detection mechanisms.
