The composition of the oil extracted from 14 different varieties ofAndropogon Sorghum var.Vulgaris

  • Published:
Oil & Soap

Summary

Fourteen varieties ofAndropogon Sorghum var.vulgaris were subjected to fractional solvent extraction. An average yield of 0.32% wax and 2.76% of oil was obtained.

The 14 sorghum grain oils varied from a light amber to green in color. They had an average refractive index of 1.4695 at 25° C. and contained 2.51% nonsaponifiable matter. The mixed fatty acids obtained from the oils had an average melting point of 28.9° C., a neutralization equivalent of 278.8, iodine value of 120.8, and thiocyanogen value of 81.5. The composition of the mixed fatty acids were calculated from the iodine and thiocyanogen values. The mixed fatty acids contained an average of 46.5% linoleic, 39.5% oleic, 7.8% palmitic, and 4.7% stearic acid.
