The electronic nose applied to food analysis

there is currently a great interest in developing new techniques for food quality assessment. electronic nose is considered an attractive technique for evaluating food aroma. in this work we present an overview of application examples of an electronic nose based on sol-gel metal oxide gas sensor array for the assessment of some foodstuffs (milk, olive oil and peach fruit). the responses of the sensor array to the flavours of these foodstuffs have been correlated with the results obtained by other standard techniques.
