Discrimination of tea quality by polymer membrane electrode based potentiometric taste sensor

Tea is one of the most widely consumed beverages all over the world due to its delicate taste. It is, therefore, essential to establish a simple and reliable analytical tool for determination (or, discrimination) of tea quality. We have taken an attempt to discriminate the black tea of different qualities/grades by means of polymer membrane electrode based potentiometric taste sensor. Different types of phosphorylated and crosslinked polymer membranes were used to discriminate different grades of black tea by measuring the tastes in terms of membrane potential.
