Physical and chemical properties of tigernut oil as influenced by variety and method of extraction

This study was carried out to investigate the physical and chemical properties of tigernut oil as influenced by variety methods extraction. Oil extracted from yellow brown varieties using mechanical screw press N-hexane, it characterized for composition. The moisture content, acid value, free fatty acid, iodine saponification value peroxide extraction ranged 2.97 3.30%, 0.28 0.56mgKOH/g, 0.55 1.12g/100g, 66.11 69.75gI/100g, 174.93 210.06mgKOHg 0.27 0.56MgH2O2, respectively. range values specific gravity, percentage impurity, cloud point, smoke point melting are: 0.64 0.99g/ml, 0.15 0.24%, 9.00 25.5°C, 170.5 204.5°C 18.0 28.5°C, However, showed that both composition were affected used in this study.
