Fatty acid composition of plant food (oil) is important for its economic and nutritional value. Assessment of fatty acid contents of two Nigerian masticatories cum traditional snacks: African walnut kernel (AW) and African elemi pulp (AE) were carried out. Samples were subjected to graded wet heat contact time based on their traditional methods of processing and their oil extract evaluated for fatty acid (FA) contents using chromatographic method. The processing methods had no statistically significant effect on both the oil and FA contents of the samples. Both samples contain nutritionally relevant levels of fat ranging respectively from 49.8±1.08 to 52.8±2.70g/100g sample and 41.93±6.03 to 42.8±4.61g/100g sample in AW and AE. A total of six fatty acids including two essential ones namely omega-6 (C18:2) and omega-3 (C18:3), were identified and quantified in the two plant foods. The predominant FAs in the plant foods were oleic acid (16.12±1.86 - 17.11±1.31g/100g fat), linoleic acid (16.88±1.66 - 18.80±1.52g/100g fat) and linolenic acid (55.95±5.68 - 57.08±6.57g/100g fat) in AW and palmitic acid (48.59±4.35 - 50.51±3.29g/100g fat), oleic acid (32.02±3.27 - 35.74±1.46g/100g fat) and linoleic acid (15.15±3.57 - 15.40±3.82g/100g fat) in AE. The study shows that on the average, one serving of AW could supply about 41.52% and 647.09% of the Recommended Daily Intakes (RDIs) for the essential FAs Linoleic and Linolenic acids respectively, while that of AE will supply about 29.13% of the RDI for Lineleic acid. Based on their essential FAs contents the plant foods apparently have potentials for applications as nutraceuticals.
