There is no much information regarding the partial replacement of palm olein with palm kernel oil. Palm olein mixed with palm kernel oil is commonly sold in Nigeria market today without proper blending and without determination of their suitability to consumer also ignorant of what ratio to be blended. Therefore, blends of palm olein (POL) and palm kernel oil (PKO) were formulated to assess their stability under elevated temperature using a fast, simple and reliable CDR palm oil tester photometric technology. The results were then compared with those obtained in POL. The blends studied were to investigate the effects of palm kernel oil partial replacement on the chemical stability of palm olein. the blends as partial replacement were missed in the ratio of PKO:POL(100:0), PKO:POL(80:20), PKO:POL(60:40) and POL:PKO(100:0), POL:PKO(80:20), POL:PKO(60:40). The POL, PKO and its blends were heated at 100, 150 and 200ᵒC. The time of heating were 20, 40 and 60mins respectively, making a total of 1 hour for heating without any frying operations. The physicochemical properties of the oil samples were fatty acid composition, free fatty acid, peroxide value, iodine value, anisidine value, cloud point, colour, melting point, viscosity and totox value were evaluated over heating time. Blending palm olein (POL) unsaturated oils with saturated (PKO) generally improved the parameters comparable to those demonstrated in palm olein (POL) and palm kernel oil alone. The result showed that as PKO was increased the concentration of saturated fatty acid also increased while unsaturated fatty acid decreased. Saturated oils were generally more stable to oxidation and less sensitive to thermal stress. Increase in the amount of PKO lead to reduction in FFA.

PT X processes crude palm kernel oil (CPKO) into products such as glycerin, fatty acid, and fatty alcohol. The purpose of this study was to determine the acid value of fatty acid using alkalimetry titration methods and gas chromatography and compare the values obtained with the PT X standard. The results showed that the AV 105 E21 and 105 E22 were following the PT X standard, with ranges respectively 355-365 mg KOH/gr and 268-275 mg KOH /gr. This indicates that the fatty acid samples produced can be sold to consumers.

This study was carried out in order to assess the quality of the type of palm kernel oil suitable for the alternative in animal oil in feed or food. To reach this objective, oil D and oil T extracted respectively from the seeds of the varieties Dura and Tenera of oil palm (Elaeis guineensis Jacq.) by the Soxhlet method using hexane as a solvent were analyzed for their physicochemical characteristics. The results obtained show that the values for the physical parameters (Oil yield, density and percentage of impurities) of both oils were similar and fell in those of the standards of Codex Alimentarius 2015. However, for the chemical parameters (Acid value, percentage of free fatty acids, peroxide value, saponification value and ester value), the values obtained for oil D were the highest, but for both oils, the values were above those recommended by the standards of Codex Alimentarius 2015, excepted the Saponification values and the Ester values which were below these standards. The determination of fatty acids composition by Gas Chromatography showed that these oils were not significantly different. Indeed, the totals saturated fatty acids were in amounts of 87.92% ± 0.17 and 87.53% ± 0.24, while the totals unsaturated fatty acids were in amounts of 12.08% ± 0.02 and 12.47% ± 0.02 respectively for oil D and oil T. The predominant fatty acid was lauric acid in amounts of 36.87% and 37.84% respectively for oil D and oil T. Thus, these palm kernel oils could be used as ingredients and preservatives in feed due to their content in lauric acid which is known to possess antimicrobial properties and also to their content in unsaturated fatty acids (oleic and linoleic acids) which are an indicator of oil quality. However, oil T seems to be more suitable for the alternative in animal oil in feed due to its percentage of free fatty acid which is less than that of oil D.
