Fatty acid composition and thermal characteristics of Malania oleifera seed oil

This study explored the physicochemical properties, fatty acid compositions, and thermal characteristics of Malania oleifera seed oil (MOSO). Our data showed that the refractive index and specific gravity of MOSO at ambient temperature were 1.461 and 0.913, respectively. The oil content, acid, perox...

Description
Summary:This study explored the physicochemical properties, fatty acid compositions, and thermal characteristics of Malania oleifera seed oil (MOSO). Our data showed that the refractive index and specific gravity of MOSO at ambient temperature were 1.461 and 0.913, respectively. The oil content, acid, peroxide, saponification, iodine value, average molecular weight, and an average number of carbon–carbon double bond per triglyceride were 47.8%, 3.62 mg KOH/g oil, 4.61 meq O 2 /kg oil, 163.16 mg KOH/g oil, 104.28 g I 2 /100 g oil, 1031.51 g/mol, and 4.24, respectively. The fatty acid profiles of the methyl esters showed the presence of 96.09% unsaturated fatty acids and 2.16% saturated fatty acids. Nervonic acid (NA) was the major component (45.04%). These results suggested that MOSO is an excellent source of essential fatty acids and NA and may be used as a potential NA resource of health supplements and medicines. Graphical abstract
