Abstract
Guar gum consists essentially of the polysaccharide galactomannan. However, small amounts of various lipid soluble compounds, including long chain fatty acids, are also present. In this investigation free and esterified fatty acids of guar gum were analysed by GLC-MS. Palmitate (hexadecanoate), oleate (9-octadecenoate) and linoleate (9,12-octadecadienoate) were found to be the main components of the lipid fraction, but several long chain saturated acids and at least two 2-hydroxy-derivatives of fatty acids are also present.
