Three solvent extraction techniques were used to recover waxy tractions from grain sorghum kernels. Yield and chemical composition of the waxy tractions obtained by reflux, bench scale (recirculated solvent), and countercurrent extraction methods were compared. Waxy traction yield from countercurrent extraction (0.200%) was significantly greater (p<0.05) than the yields of wax from both reflux (0.184%) and bench-scale (0.179%) methods. The waxy traction extracted using the bench-scale method showed the greatest relative amount of long-chained (primarily C:28 and C:30) alcohols while the countercurrent-extracted wax showed the greatest relative amount of long-chained fatty acids and fatty aldehydes. Countercurrent extraction removed a higher additive percentage of fatty aldehydes, acids, and alcohols than reflux or bench-scale extraction method.
