Abstract

The current study aimed to evaluate the physicochemical properties and chemical compositions of Balanites aegyptiaca seeds and seed oils collected in southern Algeria; the seed oil was extracted using a screw press to separate the crude oil. The elemental composition of the seed revealed a high metal concentration of magnesium (1.7±0.2 mg/g) in the seed kernel, and a low concentration of chrome and lead. The total protein content of the seed averages (0.96±0.03%). Balanites aegyptiaca provided a yield of 26.3±0.16 crude oil. The physical parameters determined were density, and refractive index. These were found to be 0.90±0.03, and 1.472±0.00 respectively. The chemical parameters evaluated include the moisture content 0.114±0.04% , saponification value (226.67±0.11 mg KOH/g) , acid value (0.93±0.05) (mg KOH/g) , iodine value (125. 33±0.07 100/g) , peroxide value 3.96±0.05 (mEq/kg) and free fatty acid; the Carotenoid composition 2.33 ±0,1 (Mg/kg). In general, the seed and the press-extracted oil had good physicochemical properties and could be used in industrial applications.
