ABSTRACT: The physicochemical
characteristics of Khaya senegalensis seed oil were investigated. Iodine value, saponification value, percentage free fatty
acid (FFA), 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 ± 0.02 and
the specific gravity was 0.9194 ± 0.04. The
established parameters fell within the worldwide and Nigerian vegetable oil
industry standards.
