“…The sensors were mounted in a flow-through cell in a sequence together with miniaturized double-junction reference electrode. The design of the modular flow system is a subject of a polish patent application [27] and was previously reported [28][29][30]. The fluid system was composed of: a two position ten port Cheminert ® valve (Vici, USA), a sample loop (200 ul), a peristaltic pump (Minipuls 3, Gilson, France) used to fill the sample loop, and a syringe pump (KDS Model 200 Series, Holliston, USA) used to introduce the carrier solution into the flow-through sensor array.…”

a b s t r a c tElectronic tongue technology based on arrays of cross-sensitive chemical sensors and chemometric data processing has attracted a lot of researchers' attention through the last years. Several so far reported applications dealing with pharmaceutical related tasks employed different e-tongue systems to address different objectives. In this situation, it is hard to judge on the benefits and drawbacks of particular e-tongue implementations for R&D in pharmaceutics. The objective of this study was to compare the performance of six different e-tongues applied to the same set of pharmaceutical samples. For this purpose, two commercially available systems (from Insent and AlphaMOS) and four laboratory prototype systems (two potentiometric systems from Warsaw operating in flow and static modes, one potentiometric system from St. Petersburg, one voltammetric system from Barcelona) were employed. The sample set addressed in the study comprised nine different formulations based on caffeine citrate, lactose monohydrate, maltodextrine, saccharin sodium and citric acid in various combinations. To provide for the fair and unbiased comparison, samples were evaluated under blind conditions and data processing from all the systems was performed in a uniform way. Different mathematical methods were applied to judge on similarity of the e-tongues response from the samples. These were principal component analysis (PCA), RV matrix correlation coefficients and Tuckerís congruency coefficients.

“…Since the above commented study, some other works on the application of etongues to the monitoring of the production of other foodstuffs [30,31] as well as alcoholic beverages production processes such as winemaking [23] and brewing process [32] An e-tongue based on 30 non-specific potentiometric sensors was applied to the monitoring of a batch fermentation process of starting culture for cheese production [31]. PLS control charts allowed detection of fermentations running under 'normal' and 'abnormal' operating conditions at an early stage.…”

“…The potential of e-tongues as fast, simple and reliable analytical techniques to partly or fully replace the complex and expensive reference methods in the brewery industry is investigated in the work by Kutyła-Olesiuk et al [32]. In this paper the application of a miniaturized hybrid e-tongue, combining both potentiometric and Regarding fermentations caused by specific microorganisms, Turner et al [36] reported one the first studies related to the use of e-tongues in fermentation process monitoring.…”

“…In this sense, there are many reports using ETs for the analysis of milk, fruit juices, coffee, wine and beer [8,9]. Applications of ETs related to beer analysis are focused on the discrimination of samples and the prediction of some taste attributes [2,10], in the correlation of features described by a sensory panel and ETs [11], and more recently, on the monitoring of beer aging and its fermentation process [12,13].…”

a b s t r a c tThis paper reports the use of a hybrid electronic tongue based on data fusion of two different sensor families, applied in the recognition of beer types. Six modified graphite-epoxy voltammetric sensors plus 15 potentiometric sensors formed the sensor array. The different samples were analyzed using cyclic voltammetry and direct potentiometry without any sample pretreatment in both cases. The sensor array coupled with feature extraction and pattern recognition methods, namely Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA), was trained to classify the data clusters related to different beer varieties. PCA was used to visualize the different categories of taste profiles, while LDA with leave-one-out cross-validation approach permitted the qualitative classification. The aim of this work is to improve performance of existing electronic tongue systems by exploiting the new approach of data fusion of different sensor types.
