Aplicación de sensores electroquímicos como herramienta de apoyo al análisis sensorial de frutas, vegetales y hierbas medicinales

Abstract

This project focused on the search for electrochemical sensors that provide support for sensory analysis in fruits, vegetables, and medicinal plants. In this research, a theoretical analysis of the published scientific studies was carried out about the foundation, operation and applications that have been developed according to the innovation of both the nose and the electronic tongue and the work in conjunction with the different types of sensors more used in each device, so that the analyzes of the organoleptic characteristics of this type of food are within the quality standards, which the use of these was based on preliminary studies with information published during the last 6 years, which is found available in the database offered by the Technical University of Ambato (ProQuest, Scopus, Science Direct) and also the free access database (Scielo, Google academic). Therefore, the results of the research are represented by graphs and tables describing the sensory support that fruits and vegetables have using these devices and the use of classification methods, as well as the volatile and chemical compounds that are commonly found. in this type of food. In conclusion, the work allowed to know that within the agroindustry it is possible to apply the electronic nose and tongue, allowing to improve the quality of these foods, as well as the improvement of the response in comparison with panels of experts.
