Mini-electronic Tongue Used to Discriminate between Coffee Samples of Different Geographical Origin
This paper presents a mini-electronic tongue that used a polymeric sensor array made from polypyrrole to discriminate between coffee samples of different geographical origin. The electronic tongue consisted of a system with a voltammetric sensor array coupled to a multichannel measuring device (...

This paper presents a
mini-electronic tongue that used a polymeric sensor array made from polypyrrole
to discriminate between coffee samples of different geographical origin. The
electronic tongue consisted of a system with a voltammetric sensor array
coupled to a multichannel measuring device (multi-potentiostat) that was
controlled by a multivariable data collection and processing application. The
samples analyzed comprised two types: a series of substances with different
chemical and taste properties and a group of samples of coffee of the Arabica
variety harvested from different geographical areas of Colombia. The electronic
tongue demonstrated the ability to discriminate between solutions with
different gustatory properties. In the analysis of the coffee samples, each
sensor showed a particular voltammetric response to each of the samples
studied. A principal component analysis was undertaken, which resulted in clear
discrimination between each of the coffee samples. It was concluded that the
portable electronic tongue equipped with polymer sensors is able to
discriminate between samples of coffee of different geographical origin. |
