Extraction and Determination of Physicochemical Characteristics Oil from Prosopis juliflora (Mesquite) Seeds

Abstract

In this study, Prosopis juliflora (mesquite) Seeds oil was extracted using normal hexane. The oil content on the seeds was found to be 3% w/w. The extracted oil was determined physicochemical properties. Prosopis juliflora oil quality was tested by determining some parameters such as viscosity, density, iodine value, saponification value, peroxide value, and acid value as well as its FTIR spectrum. The iodine values (IV) was found to be (97.157 I_2 g/100g), saponification value (SV) was about (186.53 KOH mg/g), Acid value (AC) was about (0.561NaOH mg/g), Density of oil was a Prosopis juliflora bout (0.8397g/ml), Viscosity of oil was e Prosopis juliflora estimated at (4.933〖mm〗^2/ sec), And the peroxide value (PV) of Prosopis juliflora was found to be (163.285ml/g). The results derived from the oil physicochemical analysis shed light into the possibility and limitation of the industrial application of the oil.
