Physicochemical and Biochemical Composition of Balanites aegyptiaca Seed and Seed Oil from Burkina Faso

In Burkina Faso, the seeds of Balanites aegyptiaca have been considered to be potentially high lipid, protein and mineral sources but seem to be neglected and sometimes unknown by communities. This study aims to complete data on seed oil and detail on amino acids and minerals composition of the seed of B. aegyptiaca for better use. Physicochemical parameters such as moisture and ash content, saponification index, iodine, acid value, peroxide value and the melting point were determined. Seed oil triglycerides, fatty acids and amino acids have been estimated throughout this study. The moisture and ash content were 3.70% ± 0.1% and 2.90% ± 0.2%, respectively. The saponification and iodine values were respectively 181.96 ± 0.4 mg KOH/g of oil and 104.86 ± 0.6 g of iodine/100 g of oil. Polyunsaturated fatty acid content (50.94%) was the most important. Triglyceride (LLO, 22.4%) was the major triglyceride. 9 essential amino acids and 9 non-essential amino acids were identified. Phenylalanine (11697.82 ± 0.00 mg/kg) was the most important essential amino acid. The content of 21 minerals was determined and the most important was potassium (9323.13 ± 0.01 mg/kg). Ca/P, Ca/Mg, Ca/Mg and Na/K ratios were 0.34; 1.18; 0.04 and 0.19 respectively. B. aegyptiaca seed oil is a source of multiple nutritional values and can be used by the population for multipurpose.
