THE CHEMICAL COMPOSITION OF YEMENI GREEN COFFEE

The present study aims to determine the proximate chemical composition of Yemeni green coffee ( Coffea arabica L.), by analyzing 70 samples which were collected between 2010 and 2011. 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. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}
