چکیده
Food quality analysis is one among the most important, complex and challenging discipline in the food sector. Due to its strict interaction with the quality of life it is extremely important to improve the performances of the methods in the field of food quality analysis. Now a days electronic noses have provided a plethora of benefits to a variety of commercial industries, including the agricultural, biomedical, cosmetics, environmental, food, manufacturing, military, pharmaceutical, regulatory, and various scientific research fields using mainly metal oxide(MOS), metal oxide field effect transistor(MOSFET), acoustic (bulk (BAW) and surface (SAW) wave) and polymer sensor. These sensors has unique advantage of providing fast results by identifying, characterizing and quantifying the target analytes of interests present in the flavor emitted by foods without destructing them. All these sensors are highly sensitive and inexpensive. However, these sensors face a numerous problems during operations in different aspects. Among the four sensors, polymer based on nano material may overcome the problems encountered by the environment including the temperature and humidity.
