ABSTRACT
Food safety and quality is the foremost duty of food-business operator to make hazard-free human life. Therefore, it is a primary concern of human well-being. To make proper food safety and quality system, it is necessary to monitor every step of food processing from farm to fork, including food product storage. However, monitoring all steps is not an easy task. It necessitates developing rapid, sensitive, safe, and efficient methods to monitor quality changes in biological, chemical, and physical hazards to meet the demand for eco-friendly processing. Nanotechnology plays a tremendous role in developing such kinds of detectors, nanosensors and biosensors. nanosensors and biosensors can be defined as a type of analytical device biologically derived material that help in the detection of any undesirable hazard or chemical changes in the food system. It is a compassionate monitoring strategy to detect the shelf-life of food products and even slight changes in packaging material responsible for food safety and quality. Use of nanosensors are varied from product to product, but the overall role of these sensors is to ensure food quality. This chapter mainly focuses on different nanosensors, their roles, and their impact on food quality monitoring, such as pesticides, contaminants, and foodborne pathogens.
