| In order to promote the application of woody plant oils in Yunnan province, the composition and content of total fatty acids and sn-2 fatty acids of Malania oleifera oil, Macaranga indica oil, Acer truncatum seed oil, Paeonia delavayi seed oil, Plukenetia volubilis oil and Hevea brasiliensis seed oil from Yunnan province were determined by gas chromatography. Based on the dietary fatty acid recommendation, the blending products of six woody plant oils were optimized by programming algorithm with the content of functional fatty acids as the index. The results showed that the six woody plant oils were rich in functional fatty acids. The linoleic acid contents in Acer truncatum seed oil, Plukenetia volubilis oil and Hevea brasiliensis seed oil were 35.92%, 39.59% and 35.78%, respectively. The α-linolenic acid content in Paeonia delavayi seed oil and Plukenetia volubilis oil were 32.02% and 4256%, respectively. Malania oleifera oil, Macaranga indica oil and Acer truncatum seed oil contained 40.10%, 48.53% and 5.32% nervonic acid, respectively. At position sn-2, the contents of nervonic acid in Malania oleifera oil and Macaranga indica oil were higher, which were 13.79% and 14.27%, respectively, while Paeonia delavayi seed oil had higher levels of linoleic acid (31.06%) and α-linolenic acid (2071%). By optimizing the ratio of the six woody plant oils, three blended oils were created with the highest levels of linoleic acid (36.3%), α-linolenic acid (9.1%), and nervonic acid (4.1%). In conclusion, the optimal ratio of six woody plant oils from Yunnan province can be used to create a blending oil which is rich in functional fatty acids. |
