Artificial tongue determination

From examination of almost 230 papers published in ISI journals over the period 1996-2009, it emerges that the many sectors in which artificial tongues have found applications go from the industrial plant processmonitoring to biomedical and clinical studies (see Fig. 2.4). As for this latter field, a number of sensors for the determination of several clinical... 

In the last decade much effort has been oriented to the fabrication of artificial olfaction machines able to determine chemical images (also odor images) of complex volatile compounds. Today many different electronic noses and tongues are available for odor detection and classification and for the creation of chemical images of liquids. 

What makes ripe strawberries taste so deliciously sweet It has something to do with the sweetness message delivered to your brain when certain molecules from the strawberry fit into receptor sites in the taste buds on your tongue. The molecules lock onto the receptors in a specific way, determined by their structure. When this happens, chemical processes that produce the sweet response are stimulated. Even molecules of artificial sweeteners, many of which are not carbohydrates and are not metabolized by the body, are capable of matching the sweet receptor sites of the taste buds. 

Gutes et al. [113] have described an automated procedure based on voltammetric electronic tongue formed by a biosensor array for the determination of glucose in fruit juice samples. Linear sweep voltammetric signals were obtained with high selectivity and artificial neural networks were used as the modeling tool.
