Extraction and characterization of crude and refined groundnut (Arachis hypogaea Linn) oil
Author(s): Anjani and M Khabiruddin
Abstract: This study investigated the extraction and characterization of crude and refined groundnut oil. Oil was extracted by Soxhlet method using petroleum ether (60-80) for 8 hours. Refining of oil was done by chemical method. Chemical properties measured during investigation were free fatty acid (FFA), peroxide value (PV), p-Anisidine value (AV), Total oxidation value (TOTOX), Conjugated dienes value (CD), thiobarbituric acid value (TBA), carotenoid, and total tocopherol. The values obtained for crude groundnut oil are FFA (2.8±0.03 % as oleic acid), PV (1.26±0.04 meq/kg), AV (7.52±0.03), TOTOX (10.04±0.01), CD (0.36±0.01 % as dienoic acid), TBA (7.17±0.04 meq/kg), carotenoid (75.6±0.09 mg/kg) and total tocopherol (670±7.5 ppm). On the other hand, chemical characteristics of refined groundnut oil was FFA (1.98±0.01 % as oleic acid), PV (0.92±0.01 meq/kg), AV (4.77±0.04), TOTOX (6.61±0.02), CD (0.21±0.04 % as dienoic acid), TBA (3.09±0.01 meq/kg), carotenoid (34.85 ±0.05 mg/kg) and total tocopherol (219±1.9). From the results it can be seen that groundnut oil has greater potential for domestic and industrial oil.
