Physicochemical Characterization and Antifungal Activity of Palm Kernel Oil from Five Traditional Oil Palm (Elaeis guineensis Jacq.) Accessions from Man Introduced at the CNRA La Mé Research Station
Abstract
Background and Objective: This study focused on five traditional oil palm accessions come from the region of Man, which were introduced through open pollination at La Mé Research Station. The different accessions collected were Blolè, Dompleu, Douèlè, Gbantongouin and Gbangbégouiné. The objective of the study was to evaluate the physicochemical properties and antifungal activity of the oils extracted from the palm kernels of these traditional palm trees. Materials and Methods: Palm kernel oil was prepared from five Dura-type accessions collected in Côte d’Ivoire, with kernels processed through depulping, drying, shelling, grinding and oven-drying prior to extraction. Total phenolic content of palm kernel oil was measured by the Folin-Ciocalteu method and expressed as gallic acid equivalents. Fatty acid profiles were determined via gas chromatography of fatty acid methyl esters. Antifungal activity was assessed using the agar dilution method against Aspergillus at three oil concentrations. All statistical analyses were performed using the Statistical Package for Social Science (SPSS) version 20. Results: The results indicated significant variations depending on the collected areas of the traditional palm tree accessions. The oil yields exhibited a range from 50.72-55.55%, with the Blolè and Dompleu accessions demonstrating the most optimal yields of 55-56%. The oxidation indices demonstrated a minimal level of lipid degradation, with palm kernel oil from Gbantogouin exhibiting the highest levels (peroxide index, 5.07 meq O2/kg, anisidine index, 1.23 and totox, 11.38). The acid value of the five palm kernel oil samples was found to be in accordance with the Codex standard of 4 mg KOH/g of oil. The palm kernel oil from Douèlè revealed its notably elevated saponification index (245.85 mg KOH/g of oil). Palm kernel oil from Blolè accession exhibited potent antifungal properties, evidenced by its capacity to impede the proliferation of Aspergillus sp. This effect was observed to be most efficacious at a concentration of 75 μL and within a 24 hrs time frame, resulting in a substantial inhibition rate of 72%. Conclusion: Palm kernel oils from traditional Man accessions have biochemical potential that could be exploited in the food, cosmetics and pharmaceutical industries.
