## Abstract

Taste masking in pharmaceutical products is a complex and subjective process that requires reliable evaluation methods. This review focuses on the electronic tongue (e-tongue), an emerging sensor-based technology designed to mimic human taste perception without the need for human panels. E-tongue systems provide objective data to support the development of palatable formulations. In this review, we discuss the principles, types of e-tongue devices, data processing approaches, and their applications in pharmaceutical research. By comparing e-tongue performance with human taste assessment, we highlight its potential as a complementary tool to traditional in vitro assays, accelerating formulation development and improving patient adherence.
