Determination of Physicochemical Properties and Fatty Acid Composition of "Kabate" Larva Oil from Timor Island

Abstract

Kabate larva oils could be produced from its larva through soxhlet extraction using n-hexane. Kabate larva, which locally in Timor Island called, can be found in the wounded stem of Sesbania gradiflora L. tree. In this work, the physicochemical properties and the fatty acid composition of Kabate larva oils were evaluated. Kabate larva oils was afforded as viscous yellow liquid with acid value, saponification value, peroxide number, iodine number, kinematic viscosity (at 100 °C) and specific gravity (15 °C) properties were 1.58 mg KOH/g; 111.28 mg KOH/g; 2.1554 meg/kg; 44.1426; 0.8159 g/mL; 40.57 mm 2 /s respectively. Based on the GC-MS analysis, it has been found out that fatty acids composition in Kabate larva oil were identified as a palmitic and oleic acid with a percentage value of 43.57 and 56.43% respectively.
