中文摘要:
      为促进云南木本植物油的应用,以产自云南的蒜头果油、印度血桐油、元宝枫籽油、滇牡丹籽油、美藤果油和橡胶籽油为研究对象,采用气相色谱法测定其总脂肪酸和sn-2位脂肪酸的组成与含量,并在满足膳食脂肪酸推荐标准的基础上,以功能性脂肪酸含量为指标,利用规划求解算法优化了6种木本植物油的调和产品。结果表明:6种木本植物油富含功能性脂肪酸,其中元宝枫籽油、美藤果油和橡胶籽油分别含有35.92%、39.59%和35.78%的亚油酸,滇牡丹籽油与美藤果油分别含有32.02%和42.56%的α-亚麻酸,蒜头果油、印度血桐油和元宝枫籽油分别含有4010%、48.53%和5.32%的神经酸;蒜头果油和印度血桐油中sn-2位神经酸含量较高,分别达1379%和14.27%,滇牡丹籽油中sn-2位亚油酸(31.06%)、α-亚麻酸(20.71%)含量较高;通过6种木本植物油的配比优化,得到满足膳食脂肪酸推荐标准的亚油酸含量最高(36.3%)、亚麻酸含量最高(9.1%)和神经酸含量最高(4.1%)的3种调和油。综上,以云南6种木本植物油为原料,通过配比优化,可得到富含功能性脂肪酸的调和油。
英文摘要:
      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 4256%, 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 (2071%). 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.
