Quality assessment of palm oil sold in some major markets in Delta State, southern Nigeria


Agbaire P. O.

Palm oil is one of the major fats and oils produced in Nigeria. It forms an important ingredient in the diet of many people in Delta State, Nigeria. The quality of palm oil is mostly determined by the following parameters: Free Fatty Acid (FFA) content, Iodine Value (IV), Peroxide Value ( PV), Moisture Content, Saponification Value (SV) and Impurity Content. The objective of this study was to determine the quality of palm oil sold in major markets in Delta State, Nigeria. The results obtained showed that the Moisture content ranged from 0.14- 0.17%, Specific gravity from 0.859-0.889, Smoke value from 114.12-116.40oC, Melting point from 34.5-35.6oC, FFA from 2.73-2.83mg KOH/g, IV from 52.55-53.66Wij’s, PV from 7.80- 8.40meq/kg, SV from 195.76-198.75mg KOH/g, Impurity 0.11-0.14, Carotene from 1376.73-1568.59mg/kg. all the parameters investigated had values within the SON/NIS standards. The results obtained after analysis of variance (ANOVA) showed that there were no significant differences (p>0.05) except for Carotene where there was significant difference (p<0.05). In conclusion therefore, from the results obtained these palm oil samples were of good quality and there were no evidence of adulteration.
