Potentials of Soil on Palm Kernel Oil Free Fatty Acid

Abstract

 Potentials of soil on Free Fatty Acid from Palm kernel Oil was conducted to correlate the soil physiochemical parameters and heavy metals to the free fatty acid of the palm kernel oil. Five samples of the soil were collected from Mbano and a sample of locally made palm kernel oil. The parameters analyzed were pH, temperature, organic matter, moisture, electrical conductivity, heavy Metals and free fatty acid of the oil. Results revealed : pH (5.57 ±0.49, 5.64 ± 0.36, 6.14 ±0.07, 5.95 ±0.16, 6.79±0.47), temperature ( 2.81 ±1.06, 28.0 ±0.83, 29.7 ±0.57, 29.7 ±0.64, 28.2 ±1.06), moisture (11.0 ±0.1, 18.0 ±0.2, 11.9 ±0.15, 12.9 ±0.25, 17.4 ±0.7), electrical conductivity ( 624 ±0.1, 541 ±0.2, 482.6 ±0.2, 477.0 ±0.1, 619.6 ±0.2) organic matter (77.7 ±0.15, 94.08 ±0.02, 48.6 ±0.25, 68.2 ±0.25, 38.8 ±0.15) Ca (0.644, 3.235, 1.453, 1.015, 1.673), Mg (1.467, 0.892, 1.483, 1.687, 1.147), K (2.017, 3.0054, 2.013, 1.0028, 2.067), Pb (0.036, 0.017, 0.015, 0.00, 0.0017), Fe (0.416, 0.826, 0.318, 0.316, 0.544), Na (0.656, 1.450, 0.908, 1.751, 1.956) cation exchange capacity (4.78, 8.58, 5.83, 5.45, 6.84) and free fatty acid (2.7 ±0.15, 4.3 ±0.15, 6.1 ±0.1,7.6 ±0.15,11.4 ±0.2). There was a strong positive correlation between the free fatty acid of palm kernel oil and soil sodium concentration. The study revealed that quality of the soil has a relationship with the free fatty acid of the palm oil.
