Abstract
A fraction C-1 which was very rich in polysaccharides and did not cont ain sucrose was isolated from high molecular weight water-soluble mate rial obtained from green coffee. After roasting, furfural was identifi ed in fraction C-1 by means of headspace-GC/MS analysis. Roasting of t he fraction C-1 clearly affected the arabinogalactan promoting a high loss of arabinose residues. We suggest that furfural found in fraction C-1 originates mainly from arabinogalactan, which, together with sucr ose appears to be the major furfural precursor in roasted coffee.
