Application of a Single-Type eNose to Discriminate the Brewed Aroma of One Caffeinated and Decaffeinated Encapsulated Espresso Coffee Type Palacín Roca, Jordi Rubies, Elena Clotet Bellmunt, Eduard Electronic nose e-nose eNose LDA Coffee aroma Espresso coffee Caffeinated and decaffeinated coffee discrimination This paper assesses a custom single-type electronic nose (eNose) applied to differentiate the complex aromas generated by the caffeinated and decaffeinated versions of one encapsulated espresso coffee mixture type. The eNose used is composed of 16 single-type (identical) metal–oxide semiconductor (MOX) gas sensors based on microelectromechanical system (MEMS). This eNose proposal takes advantage of the small but inherent sensing variability of MOX gas sensors in order to provide a multisensorial description of volatiles or aromas. Results have shown that the information provided with this eNose processed using LDA is able to successfully discriminate the complex aromas of one caffeinated and decaffeinated encapsulated espresso coffee type. 2022-12-09T11:56:57Z 2022-12-09T11:56:57Z 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://doi.org/10.3390/chemosensors10100421 2227-9040 http://hdl.handle.net/10459.1/84507 http://hdl.handle.net/10459.1/84507 eng Reproducció del document publicat a https://doi.org/10.3390/chemosensors10100421 Chemosensors, 2022, vol. 10, núm. 10, 421 cc-by (c) Jordi Palacín, Elena Rubies, Eduard Clotet, 2022 info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by/4.0/ MDPI
