| 中文摘要: |
| 采用不同溶剂对伽师瓜籽油进行提取,用气相色谱-质谱技术对所得伽师瓜籽油脂肪酸组成进行分析,同时测定了伽师瓜籽油常规理化性质.结果显示,伽师瓜籽油的最佳提取溶剂为石油醚,出油率为48.38％,其油不饱和脂肪酸含量为79.73％,亚油酸含量高达61.74％.伽师瓜籽油相对密度(d204)为0.905 8,折光指数(n20D)为1.472 8,酸值(KOH)为3.39 mg/g,皂化值(KOH)为169 mg/g,碘值(Ⅰ)为115.85 g/100 g,过氧化值为5.4 mmol/kg. |
| 英文摘要: |
| The Jiashi melon seeds oil was extracted by Soxhlet extraction method with different solvents,and the fatty acids composition of the oil was analyzed by gas chromatography-mass spectrometry(GC-MS).In addition,the physicochemical properties of Jiashi melon seeds oil were also determined.The results showed that the optimal extraction solvent was petroleum ether,and its oil yields was 48.38%,the total unsaturated fatty acids of the oil was 79.73% with linoleic acid being the dominant fatty acid(61.74%).The rel... |
