Abstract
Nanostructure films used in assessment of chemical fingerprint in complex samples bring economic importance for quality control. In this regard impedimetric based multi-sensors system fabricated with nanostructure polymers was applied for Indian tea classification from two different origin. The important indicator for black tea quality such a total flavonoids and polyphenols was estimated to investigate the chemical composition. The generated data from multi-sensor analyzed using chemometric tool such as principal component analysis (PCA) and partial least squares discriminant analysis (PLSDA. This helped visualize and classify the two classes of tea, respectively. The final results promise the capability of the multi-sensor device in classification of Indian tea according to their origin.
