“…Indeed, these oils were richer in saturated fatty acids and thus more stable. These results are in agreement with those obtained by [21]. These saturated fatty acids are essentially a source of energy for human diet as well as for animal.…”

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.

“…Thus, it could also be used as a preservative in the feed. This palm kernel oil is an appreciable source of saturated fatty acids but contains also monounsaturated and polyunsaturated fatty acids [21]. It has been shown that, at a temperature of 40°C, it can be stored for 6 months [22].…”

“…Indeed, these ratios were 0.250 and 0.220 respectively for OD and OT (Table 2). These results were similar to those obtained by Agboola et al, (2015) and Yapi and Kouadio (2020). Means (means of three samples analyzed) in each row followed by different letters are significantly different (p<0.05).…”

“…In Côte d'Ivoire and many African countries, oil extracted from the kernel is used for seasoning the dishes and as food preservative (Yapi & Kouadio, 2019). Previously, Agboola et al, (2015) have shown that palm kernel oil contained saturated fatty acids as well as monounsaturated and polyunsaturated fatty acids used in African dishes. However, it is not used only for diet.…”

The objective of this study was to determine biochemical composition of palm kernel oils produced and consuming in Côte d’Ivoire in order to find out those more suitable for human diet. Our preliminary investigations showed that palm kernel oils consumed in Côte d’Ivoire were those extracted from varieties Dura and Tenera of oil palm (Elaeis guineensis Jacq.) Thus, the types of oils analyzed in this study were oil extracted from the variety Dura (OD) and oil extrated from the variety Tenera (OT). The GC-MS was used to determine the biochemical composition of these oils. The results obtained show that in each oil, seventeen fatty acids were identified by GC–MS. However, among these fatty acids, undecylenic acid was identified only in OD and heptanoic acid was identified only in OT. The two types of oil are rich in saturated fatty acids. However, OD had a relatively higher unsaturated fatty acids content. For the other compounds identified, OT had significantly the highest contents of polyphenols, α-tocopherol and sterols with the predominance of β-sitosterol. These results support that palm kernel oil extracted from the variety Tenera is rich in natural compounds that could be developed as nutraceuticals and phytomedicine. However, some unexpected compounds such as lactones were also identified in the two types of oils. Moreover, it is noted that these lactones were more abundant in oil extracted from the variety Dura (OD).

“…It is also used for seasoning the dishes and as a food preservative in Ivory Coast where this oil is abundant and affordable affordable (Yapi & Kouadio, 2019). This palm kernel oil is an appreciable source of saturated fatty acids but contains also monounsaturated and polyunsaturated fatty acids (Agboola, et al, 2015). Moreover, the palm kernel oil with its richness in lauric acid which possesses antimicrobial and antiviral properties can be recommended for the diet of people living with HIV AIDS (Anonyme, 2010;Anonyme, 2012).…”

The investigation of the antimicrobial and antioxidant activities of palm kernel oils extracted from varieties Dura (oil D) and Tenera (oil T) of oil palm (Elaeis guineensis Jacq.) and the relationship to their chemical composition were carried out in this study. The results obtained show that oil D had the greatest antimicrobial activity. The analysis of gas chromatographic coupled to mass spectrometry (GC-MS) showed that this oil D contained in addition to the lauric acid, the undecylenic acid which both possess antimicrobial activity. This undecylenic acid was not identified in oil T. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay and the Fe3+ reduction test (FRAP) used to evaluate the antioxidant activity of the palm kernel oils had showed that oil T had the greatest antioxidant activity with a concentration inhibiting 50% of the reaction (IC50%) of 750 mg/L. It was also noted that, this oil T had also the highest contents in polyphenols, α-tocopherol and sterols with predominance of β-sitosterol. Moreover, the β-sitosterol is known to possess a regulatory role of the immune system.The findings of this study provide thus, useful information which may help customers to make the best choice in the consumption of these oils.
