| Abstract: |
Coffea is considered as a large genus (with more than 90 species) of flowering plants belongs in the family Rubiaceae. However, coffee ranks as one of the major commodity crops in the world and is the essential export product of some countries.
Moreover, coffee beans found on the market are produced from two different species of the Coffea genus such as Coffea arabica and Coffea canephora syn. Coffea robusta .
Nowadays, due to its pleasant taste, aroma, stimulant effect, and health benefits, coffee is one among the most widely consumed beverages throughout the world includes Rwanda country. Both species of coffee present a rich source of biologically active compounds such as caffeine.
Caffeine is defined as a xanthine alkaloid compound that acts as a stimulant in humans. It is normally found in the leaves and beans of the coffee plant. In addition to that, caffeine is widely used to enhance alertness and improve performance as it acts as psychostimulant.
Consequently, the strong pharmacological effects of caffeine have led to consumer demand for caffeine-free coffee beverages. Due to the high consumption rate of caffeine and its potential physiological effects, both health professionals and consumers need to know the exact caffeine content in food. The way to assess their content to find a more precise relationship between the amounts of consumed caffeine and it’s physiological effects ,it is therefore important to precisely determine the caffeine content in different coffee types.
The research’s objective was to determine Caffeine content in coffee growing in different Regions of Rwanda in order to identify the coffee region that contains the highest amount of caffeine. The Coffee samples presenting four growing regions of Rwanda have been taken from NAEB and brought to the College of Science and Technology (CST) chemistry department Laboratory. Quantitative analysis of Caffeine was performed by using a UV-Visible spectrometer (UV-Vis spectrometer) at 650 nm. The results showed that the highest caffeine concentration was obtained from coffee grown in the Western province region presented by GASHONGA Coffee (RUSIZI District) with 9.4±1.962 ppm of caffeine concentration. This was followed by coffee grown in the Southern province region presented by MARABA Coffee (HUYE District) which contains 7.5333±0.8885 ppm of caffeine concentration. The third coffee in caffeine concentration was MUSASA Coffee (GAKENKE District) grown in the Northern Province region which contains 3.8±1.270ppm of caffeine. The last caffeine concentration was obtained in coffee from Eastern province, presented by HUMURE Coffee (GATSIBO District) with 3.2667± 1.578ppm of caffeine Western province region presented by GASHONGA Coffee (RUSIZI district).
