Abstract

This research studied the functional quality of oil extracted from Tiger nut using two different methods (Mechanical extraction and Chemical solvent extraction methods) and the results revealed Moisture: 0.394 ± 0.0021 and 0.226 ± 0.0077, Fatty acid; 0.408 ± 0.0098 and 0.311 ± 0.0005, Impurity; 0.045 ± 0.0021 and 1.7025 ± 0.0106, Saponification; 206.765 ± 4.859 and 203.745 ± 0.7707, Extraction Efficiency; 41.555 ± 0.077 and 88.85 ± 0.353, iodine value; 91.236 ± 0.0047 and 87.00 ± 0.466, Peroxide; 8.381 ± 0.0707 and 0.7635 ± 0.012,Specific gravity: 0.908 ± 0.0035 and 0.880 ± 0.015, Flash Point: 147.845 ±0.021 and 156.355 ± 0.077, Pour Point: 4.005 ± 0.0071 and 4.00 ± 0.00, Cloud Point: 9.050 ± 0.0707 and 7.95 ± 1.343, Refractive Index: 1.416 ± 0.028 and 1.718 ± 0.0056, Colour: Golden Yellow and Dark-brown were obtained for mechanically and chemically extracted oil respectively. The results defined the two different oils and the values are within the WHO permissible limits for the various characterization factors. However either of the oil has some advantages and disadvantages over the other based on the values obtained.
