| 中文摘要: |
| 香榧为我国特产的名贵干果,本试验首先采用正交试验研究了超临界二氧化碳萃取香榧籽油的工艺条件；然后对香榧籽油的脂肪酸采用 GC/MS 进行分析,并与橄榄油、花生油、山茶油、芝麻油的脂肪酸进行比较。结果表明,超临界CO2流体萃取的最佳工艺条件为萃取压力30 Mpa,温度50℃,萃取时间2 h,萃取率达16.2%；香榧籽油主要含有亚油酸(38.23%)、油酸(35.52%)、棕榈酸(7.45%)、金松酸(7.41%)等10种脂肪酸,金松酸是具有较强生理活性的特殊脂肪酸。香榧籽油主要脂肪酸种类在所检测的5种油中最丰富,其脂肪酸组成与芝麻油较相似,单不饱和脂肪酸与多不饱和脂肪酸较为均衡(36.39%、49.80%)。本研究可为香榧籽油作为高档功能性油脂的开发利用提供基础数据。 |
| 英文摘要: |
| The seed of Chinese torreya (Torreya grandis cv. Merrilli) is a special rare native nut in China. The extraction of torreya seed oil with the supercritical carbon dioxide technique was carried out. Then its fatty acid was analyzed by GC-MS, and compared with olive oil, peanut oil, camellia oil and sesame oil. Results show that the obtained optimum extraction conditions are pressure 30 Mpa, extraction temperature 50℃, and time 2 h and extraction yield is 16.2%. Linoleic acid and oleic acid are most abundant with mass fraction of 38.23% and 35.52%, followed by palmitic acid (7.45 %) and sciadonic acid (7.41%)．Sciadonic acid is an unusual bio-active fatty acid. The fat acid components of torreya seed oil are similar to sesame oil and have the richest varieties among the five vegetable oils analyzed. The MUFA (36.39%) and PUFA (49.80%) in torreya seed oil are relatively balanced. These data would be helpful for the further development and utilization of Chinese torreya seed oil as functional food． |
