Electronic and bioelectronic tongues, two promising analytical tools for the quality evaluation of non alcoholic beer

Authentication of the flavor of non alcoholic beer and control of its quality according to the present standards is an actual challenge in brewery. Electronic and bioelectronic tongues, which could be known as the taste sensors, are the advanced and emerging analytical technologies simulating the taste detection modality of the human tongue by means of electrochemical sensors or biosensors array. Although, application of electronic tongue has been reported for alcoholic beers but no work on the flavor sensory evaluation of non alcoholic beer by use of bioelectronic tongue has been published. Employment of electronic and bioelectronic tongues can reduce some problems in quality control of non alcoholic beers. Recently published works show a promising perspective for the fulfillment of this goal. This paper discusses and concludes that these analytical tools have a high potential application in brewery to monitor the flavor of non alcoholic beer in the immediate future.
