Coffee’s volatiles was extracted and adsorbed in a silica cellulose matrix. Silica from rice husk ash and cellulose from nata de coco was made adsorbent, from which volatile compounds can be adsorbed and released. Extracts from Arabica coffee types were applied. The objectives were to make an environment-friendly air freshener from coffee extracts and silica cellulose materials. GC-MS was employed to determine the volatiles released at 1st, 2nd, 7th and 14th days of adsorption time. The results showed interesting profiles of Arabica coffee with organic acid and ester components. A study about the surface dynamics of certain volatiles is underway. © 2023 American Institute of Physics Inc.. All rights reserved.
