Innovative Application Electronic Nose and Electronic Tongue Techniques for Food Quality Estimation

Abstract

Smell and Taste are the two very imperative senses which enable us in detection and discrimination of several volatile organic compounds, which in turn may be identified as indicators for specific desirable or undesirable conditions in various industries. Electronic nose and electronic tongue are recent technologies which have attracted many researchers to work in order to provide effective solutions for various industrial applications. This paper overviews the functionality of the electronic nose and electronic tongue and presents a summary of different sensors used for the said technologies. Also, a comparison between an E-nose and E-tongue is presented on the basis of relative figure of merits. A case study is presented wherein application of artificial nose and artificial tongue is discussed for the quality analysis of the fruits. The paper is aimed to emphasis on the possibilities of combining e-nose and e-tongue techniques to enhance the overall performance of the system used for food quality analysis. An E-nose combined with an E-tongue can be a highly efficient, non-invasive, fast and low cost method of quality analysis that can serve the industry and society for the betterment of the mankind.
