摘要
采用索氏提取法提取了在陕西养殖的鸵鸟油,室温分离得到液体油和固体脂。采用化学方法和气相色谱仪测定了两者常规理化指标和脂肪酸组成。结果表明,鸵鸟液体油和固体脂除碘值外其他理化指标稍有不同,其中脂肪酸组成及含量也有差异。液体油主要含有棕榈酸、油酸和亚油酸等,不饱和脂肪酸含量为63.96%,其中油酸含量最高,达到42.23%;固体脂主要含有棕榈酸、硬脂酸和油酸等,饱和脂肪酸含量为55.93%,其中棕榈酸含量最高,为45.23%。
Ostrich oil was extracted by Soxhlet method, and then separated to liquid oil and solid fat at the room temperature. Their physicochemical properties and composition of fatty acids were detected by chemical and GC analysis methods. The results showed that the ostrich liquid oil and solid fat had the slight differences in physicochemical properties except iodine value. The main fatty acids in liquid oil were palmitic acid,oleic acid and linoleic acid, and its unsaturated fatty acid content was 63.96%, of which the highest oleic acid content reached 42.23%. The main fatty acids in solid fat were palmitic acid, stearic acid and oleic acid,and its saturated fatty acid content was 55.93%, of which the highest palmitic acid content reached 45.23%.
