中华猕猴桃种子不饱和脂肪酸的成分分析及其萃取工艺研究

CONSTITUENT ANALYSIS OF UNSATURATED FATTY ACID AND TECHNOLOGY OF EXTRACTION FROM ACTINIDIC CHINENSIS PLANCH SEEDS

用中华猕猴桃 (ActinidiachinensisPlanch)种子提取不饱和脂肪酸 ,经分析测试 ,产品中主要脂肪酸含量为棕榈酸 4 .82 %、硬脂酸 3.72 %、油酸 13.11%、亚油酸 10 .36 %、亚麻酸 6 4 .99%、花生四烯酸 2 .0 3%。采用正交试验得出最佳萃取工艺为 :萃取温度 6 0℃、萃取时间 30min、液料比 (石油醚∶猕猴桃种子 ,mL∶g)4 .0∶1.0、萃取次数 3次 ,按该工艺条件 ,萃取平均得率为 2 9.70 %。

Unsaturated fatty acid was obtained from Antinidia chinensis Planch seeds.The contents of each fatty acid component in product are as follows:palmitic acid 4.82%,stearic acid 3.72%,oleic acid 13.11%,lindeic acid (10.36%),linolenic acid 64.99%,arachidonic acid 2.03%,respectively.The optimum conditions of extraction by (orthogonal) tests are:temperature 60 ℃,time 30 min,ratio of liquor to material:petroleum ether(mL)∶seeds(g) (4.0∶1.0),extract 3 times.Under such conditions,the yield of the extraction is 29.70%.
