Chemical composition analysis of palm oils in Ijebu-Ode, Ogun state

Abstract

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 Ijebu-ode Ogun 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. This study attempts to investigate the chemical composition analysis of palm oil. sold in major markets in ljebu-Ode, Ogun State, Nigeria. Twenty branded and unbranded palm oil samples were collected from three markets in Ijebu-Ode. They were analyzed for saponification value. Acid value and peroxide value using [1][2]. The results obtained showed that the Saponification value (SV) ranges from 183.03±0.15-220.89±0.05mgKOH/g. Acid value (AV) from 8.64±0.10-12.96±0.05mgKOH/g and Peroxide value (PV) from 7.50±0.10-15.00±0.15meq/kg. All the parameters investigated had values within the [3]/[4] standards. It can thus be concluded that palm oil from Ijebu-ode has a good shelf-1ife, is suitable for both domestic and industrial applications and there is no evidence of adulteration notable from their chemical compositional analysis.
