The goal of this study is to determine the physicochemical parameters of palm kernel oil produced from traditional types in Côte d'Ivoire's Mountain district.
Palm kernels were collected from women who produce crude palm oil in three departments in Cote d'Ivoire's western region. Each department purchased 50 kg of palm kernel from each supplier.
The study took place between June and September of 2017. The palm kernels were gathered and processed at the Félix Houphout-Boigny University's Biochemistry and Food Sciences Laboratory in Abidjan.
Methodology: Maceration was used to extract the palm kernel oils, and standard procedures were used to determine their physicochemical parameters.
The results demonstrate that the values for the physicochemical parameters of palm kernel oils from the three departments were similar and aligned with the Codex Alimentarius 2019 criteria. Physicochemical parameters, on the other hand, differ statistically (P0.05) between departments. The yields of extracted oils ranged from 39.64 2.14 percent to 52.26 1.16 percent. Between 1.453 0.01 to 1.454 0.002 is the refractive index. Between 0.90 and 0.91 is the relative density. Insoluble contaminants were found in concentrations ranging from 0.06 to 0.09 percent. Moisture and volatile matter contents ranged from 0.62 0.05 percent to 1.94 0.07 percent. The acid value and free fat acid percentage range from 6.37 0.65 to 8.54 0.57 mg KOH/g and 3.20 0.31 to 4.29 0.28 percent, respectively; the saponification value is between 216.02 8.96 mg KOH/g and 248.16 2.40 mgKOH/g; the iodine value is between 17.52 0.43 and 19.05 0.95 g of iodine per 100 g of fat; and the peroxide value is between 6.02 1.13 The presence of fatty acid and unsaponifiable lipids was discovered in the lipid composition of these fats. Lauric acid (50.50 - 51.00%), myristic acid (18.35 - 18.80%), and oleic acid (50.50 - 51.00%) are the three primary fatty acids (12.80 - 13.92 percent ). The high concentration of water and volatile substances in the environment may encourage enzymatic activity. This indicates that the oils in this study are more likely to undergo hydrolytic or enzymatic changes that result in the creation of secondary products such monoglycerides and diglycerides.
Conclusion: Palm kernel oils from the three departments had good physicochemical qualities, indicating that they might be used as food and non-edible items in many homes and companies in Côte d'Ivoire. There is currently insufficient information accessible regarding palm kernel oil from Côte d'Ivoire's western region, and this study extensively investigated it, providing useful information for the Ivorian oil palm sector.Author(S) Details
