Descripción:	Coffee is one of the most widely consumed drinks in the world and is a commodity with high production and significance. The coffee beans are obtained after washing stages to remove impurities, drying, and peeling the skin. Wetting rote eliminates coffee compounds, increasing the quality of the final bean [1]. The elevated abundance of CGA makes this polyphenol an indicator of the polyphenols and quality products [2]. Colorimetric sensors are a promising alternative, in which the color change occurs by analyte and sensor array interaction turns easy visual monitoring [3]. Silver-based materials are highly suitable for sensor platforms to electrons on the surface interacting with electromagnetic radiation in the visible spectrum region (400 nm). Thus, the target molecule promotes a surface modification accompanied by a change in color [4]. A colorimetric sensor applied to CGA polyphenol has yet to be fully elucidated [5], making further studies necessary. Therefore, this study aimed to evaluate a sensor based on faujasite zeolite with a surface modified with Ag+ ions (AgFAU) as a colorimetric sensor for detecting the polyphenol CGA.
