It is essential to manage the food requirement for the growing population.
Food safety is important for health, but maintaining nutrients and food quality is also
necessary for better health. Food storage and packing should be done carefully in order
to avoid food contamination and ensure long-term food storage. There are various types
of food hazards (biological, chemical, and others) that may contaminate food and cause
food poisoning, foodborne diseases, allergies, and other health issues. For food quality
examination, traditional procedures, such as chromatographic methods, are used, but
these are time-consuming, labour-intensive and require an expert in instrumentation. It
is critical to inspect the quality of food on a regular basis and as quickly as feasible.
The greatest approach for overcoming these issues is the use of biosensor. As food
additives and pollutants, the biosensor is extremely quick, sensitive, and selective.
Biosensors are equipped with a transducer and a biological identification element,
allowing them to evaluate food quality. Pesticides, poisons, microbial growth, protein,
metals, fatty acids, antibiotics, vitamins, and other compounds can all be detected in
food using biosensors. Biosensors have a wide range of applications in the food
industries but there is also the demand for novel, inexpensive, simple, small-sized,
portable, and multifunctional biosensors for food analysis. Biosensor can also detect
food additives and pollutants throughout the packaging process
