Abstract

Coffee is a brewed beverage which is made from the bean seeds of plants belonging to the Rubiaceae family. The consumption of coffee has grown over time for its appreciated taste and beneficial effects on health. Commercial samples of Liven alkaline coffee, Nescafe original coffee and Nescafe original decaffeinated coffee were subjected to phytochemical screening in order to detect classes of phytochemical compounds present in them. Proximate analysis was conducted as well using standard procedures. The results of the study showed that the coffee samples contained a significant number of phytochemicals which includes carbohydrates, flavonoids, saponins, alkaloids, tannins and polyphenols. The Liven alkaline coffee have highest quantity of alkaloids (3.10 ± 0.82 %) and carbohydrates (0.134 ± 0.009 mgGE/g) compared to the Nescafe original coffee; alkaloids (1.43 ± 0.80 %) and carbohydrate (0.031 ± 0.005 mgGE/g) and the Nescafe original decaffeinated coffee; alkaloids (2.57 ± 0.12 %) carbohydrate (0.041 ± 0.010 mgGE/g). The caffeine content of the three samples varied appreciably with the Nescafe original coffee containing 132.25 PPM, Liven alkaline coffee having 20.53 PPM and Nescafe original decaffeinated coffee having 8.33 PPM. The proximate analysis revealed that Liven alkaline coffee have the highest ash content with 3.3 % while Nescafé original coffee have the highest moisture content with 5.1 %.
