Biosensors in food safety and quality have become indispensable in today’s world due to the requirement of food safety and security for human health and nutrition. This book covers various types of sensors and biosensors that can be used for food safety and food quality monitoring, but these are not limited to conventional sensors, such as temperature sensors, optical sensors, electrochemical sensors, calorimetric sensors, and pH sensors. The chapters are framed in a way that readers can experience the novel fabrication procedures of some advanced sensors, including lab-on-a-chip biosensors, IoT-based sensors, microcontroller-based sensors, and so on, particularly for fruits and vegetables, fermented products, plantation products, dairy-based products, heavy metal analysis in water, meat, fish, etc. Its simplistic presentation and pedagogical writing provide the necessary thrust and adequate information for beginners, scientists, and researchers. The book offers comprehensive coverage of the most essential topics, which include the following: Fundamentals of biosensors Overview of food safety and quality analysis Major toxicants of food and water Fabrication techniques of biosensors applicable for different segments of the food industry This book serves as a reference for scientific investigators who work on the assurance of food safety and security using biosensing principles as well as researchers developing biosensors for food analysis. It may also be used as a textbook for graduate-level courses in bioelectronics.
