ABSTRACT

Food safety is causing a rising concern in the present world as the microbial contamination of food products may result in various food-borne illnesses, which may sometimes result in food-borne disease outbreak. Every year, approximately a 25 per cent reduction in global food production occurs due to spoilage. Wastage of food happens at all stages of the food chain and across all types of foods. Food safety and nutritional quality have always been a priority issue for pro-ducers, food safety regulators, and the food industry. Hence, accurate and quick monitoring of food quality is necessary throughout the various stages, like food production, transportation, storage, and consumption. In this aspect, nanosensors have gained attention among other food-analysis techniques due to its promising properties, like enhanced accuracy, quick response, etc. This chapter delves into the new aspects of nano-based biosensors, which can be used in various sectors of the food industry. Here, the special emphasis will be given to improved properties of nanosensors, while explaining the role of development of biosensors for the detection of pathogens, toxins, food adulterants, preservatives, etc. in food and use in food quality management.
