Abstract- Coffee is the most important agricultural commodity and beverage worth up to US $ 14 billion annually. More than 18 countries, including Yemen, cultivate coffee. More than 125 countries export and re-export coffee. Providing a livelihood for 100 million people around the world. More than 50 developing countries are earning 25 %, of their foreign exchange. Coffee production in Yemen has been on a constant decline over the last decades. The surface cultivated 34 686 hectares and the yearly production reached 19 430 tones in 2008. It is generally acknowledged that more then 105 000 families of farmers are growing coffee in 15 Governorates and 200 districts mountains areas.
The present study aims to determine the proximate chemical composition of Yemeni green coffee (Coffea arabica L.), by analyzing 70 samples. The moisture content, crude proteins, total lipids, carbohydrates and ash % averages were 6.99 ± 0.48, 10.95 ± 0.44, 6.13 ± 0.36, 22.12 ± 1.77 and 4.16 ± 0.52 %, respectively. Other chemical constituents such as dextrins, chlorogenic acid, and caffeine % averages were 35.89 ± 2.59, 7.19 ± 0.4 and 1.49 ± 0.29 %, respectively. Finally organic and metallic pigments were not found in any of Yemeni neutral green coffee samples.
