Abstract:
This work evaluated the five tropical coconut species and its physicochemical characteristics on oils extracted in south-east Nigeria, with a view to assessing their suitability. The oil extract serves as major source of energy recovery due to high percentage of lauric acid, which contributes to new cell formation. The physicochemical parameters includes color, odor, solubility, oil yield, saponification value, iodine value, peroxide value, and free fatty acids were determined using standard methods of analysis. . Kings Coconut (S1) recorded the highest oil yield of 10.7±0.94% than other species while Macapuna Coconut (S4) recorded the lowest yield of 6.23 ± 0.12 %. Iodine value for Fiji Dwarf Coconut (S5) was 7.27± 0.20 mgKOH/gs, which was the lowest compared to other species while Kings Coconut (S1) recorded the highest value of 9.37 mgKOH/gs, Fiji Dwarf Coconut (S5) recorded the highest Saponification value of 258 ± 1.63 mg KOH/g Oil while Kings Coconut (S1) and Maypan Coconut (S2) recorded the lowest value of 252 ± 0.00mg KOH/g Oil. Macapuna Coconut (S4) recorded the highest Free Fatty Acid value of 0.39 ± 0.02% while Kings Coconut (S1) recorded the lowest value of 0.1 ± 0.01%, Macapuna Coconut (S4) recorded the highest value of 0.64 ± 0.0 meq/kg while Kings Coconut (S1) recorded the least value of 0.38 ± 0.01 meq/kg. However, there were no significant differences among species at 95% confidence level in the physicochemical properties except for Free Fatty Acid. The result shows that the physical and chemical parameters of the solvent extracted oil from different species of coconut were within the permissible range as recommended by NAFDAC and APCC indicating that all the species may be used for domestic and industrial purposes. The results demonstrate the suitability of the oils which can be used by manufacturers in pharmaceutical sectors, cosmetic sector, and food vendors.
