The Coffea arabica (Arabica) and Coffea canephora (Robusta) are the most important coffee species which are traded in the world. The research was intended to study the different profiles of the bean and roasted Arabica and Robusta coffee originated from Semendo South Sumatera, Indonesia. The green and roasted samples were analyzed by using FTIR in the region 4000-400 cm−1. The color was investigated using Konica Minolta Color Reader expressed in L*, a*, and b* Commission Internationale de Eclairage scale parameters and caffeine content by HPLC. The results showed that Arabica and Robusta coffee have similar spectra but are different in absorbance. Spectral correlation with the library common materials in the region 3495-499 showed that the spectra of roasted Arabica and Robusta have spicy and herb flavors such as Coriander seed, Red pepper seed, Carrot seed, and Cumin seed. The spectra of roasted Arabica match with the spectra of Q10, Vitamin A, Saw Palmetto, while Robusta coffee has a match with the spectra of Hersey cocoa. They differ in color, volume, and pH. The caffeine content of Robusta bean (2.10 %) was higher than that of Arabica (1.17%). [ABSTRACT FROM AUTHOR] |
