Abstract

Plant secondary metabolites are essential, biologically active compounds that play an important role in the plant’s defense mechanism. While primary metabolites often showcase the plant’s metabolism through synthetic pathways, secondary metabolites are unique to the species they belong. Terpenes, phenolics, and nitrogen-containing compounds have been studied over the years for their application in human health and nutrition. These plant bioactive compounds enrich the food we consume, but reports of its undesirable effects have also been recorded. Hence, it bears on the global issue of food safety and security which requires accurate analytical techniques to determine its levels in food. A biosensor is an analytical device that is able to respond to an external chemical stimulus and convert it into readable data. The data observed can be in the form of an electrical signal or a change in absorbance. Different biosensors have been developed to determine the presence of secondary metabolites such as polyphenols, vital for nutraceutical analysis of food. Compared to conventional detection techniques, biosensors offer a wide range of advantages, including better accuracy, higher precision, and low occurrence of false positives. Being quick and versatile allows these biosensors to be used in an industrial setting or even available at the consumer level. This chapter highlights the different types of biosensors and recent advancements in the biosensing of plant secondary metabolites.
