Physicochemical Properties of the Seed Oil of <i>Khaya senegalensis</i>

Abstract

The physicochemical characteristics of Khaya senegalensis seed oil were in vestigated. Iodine value, saponification value, percentage free fatty acid (FF A), acid value, and peroxide value were the chemical parameters examined in the oil analysis, while specific gravity and refractive index were examined as physical parameters. The results showed that the acid value was 1.18 ± 0.01, the saponification value was 191.76 ± 0.01 mgKOH/gm, and the iodine value was 102.79 ± 0.01. It contained 0.59 ± 0.01 percent free fatty acid. The value of peroxide was 6.83 ± 0.01 meq/kg. The results showed that the refractive index was 1.462 ± 0 . 0 2 and the specific gravity was 0.9194 ± 0 . 0 4 . The established parameters fell within the worldwide and Nigerian vegetable oil industry standards.
