| Popis: | Objectives: The aim of this work is shows the elaboration of a device based on PSOC technology called electronic tongue, which is able to separate samples of raw milk. Methods/Statistical Analysis: The device developed consists of an electrochemical sensor array based on conductive polymers, a multi-channel system of electrochemical measurements, responsible for acquire and processing signals from substances trough sensors, and a data processing stage capable to discriminate different substances with multivariate statistical methods. Findings: The results show how this system was capable of offering unique signal front for each different samples of milk, the data obtained were discriminated by data processing stage thanks to the use of a multivariate statistical method called Principal Components Analysis. This work has been focused on the dairy sector, with the purpose to provide a device capable to make inspection of the raw milk in field. Application/Improvements: The device elaborated in our laboratory is compact and portable (347 g). The signals registered with the sensor array of the electronic tongue allowed to discriminate adulterated milk samples. Keywords: Electronic Tongue, Electrochemical Sensors Array, PSOC Technology, Milk |
