Electronic Tongue on a way towards the universal bitterness scale

The present work deals with the development and application of the artificial sensory system (Electronic Tongue) to quantification of the bitter taste of various chemically dissimilar substances and suggests a universal approach for artificial sensory evaluation of bitterness, irrespective of chemical nature of the substance eliciting bitter taste. This approach to artificial quantification of bitterness is practically feasible and may be particularly useful on the early stages of development of novel API in pharmaceutical research and for flavour control of various pharmaceutical compositions, healthcare products and food ingredients.
