| 摘 要： | 利用索氏提取法提取白玉蜗牛肉冻干粉中的脂肪酸,通过三氟化硼法进行甲酯化。以气相色谱-质谱联用仪进行组分鉴定。结果表明,蜗牛肉冻干粉的总脂得率为2.73 ％,在总脂的甲酯化产物中检测鉴定出15种脂肪酸,含9种不饱和脂肪酸,占总量的72.22 %,其中亚油酸占17.42 %,油酸占16.54 %,花生四烯酸占13.13 %,EPA占2.14 %。白玉蜗牛肉富含多不饱和脂肪酸(占总脂的48.03 %),可以用于多不饱和脂肪酸类新型功能食品与保健品的开发。 |

| Abstract: | The fatty acids were extracted from the meat powder of Achatina folica by Soxhlet extraction. The best yield of fatty acids was obtained with Petroleum ether solvent, and the extracting ratio up to 2.73%. Among the methyl ester products of fatty acids, 15 compounds were identified by the gas chromatography and mass spectrometry. The content of linoleic acid is 17.42%, oleic acid is 16.54%, arachidonic acid is 13.13%and EPA is 2.14 % in total lipids. Our result shows that the content of poly unsaturated fatty acid(PUFA) is 48.03% in total lipids of Achatina fulica meat and the Achatina fulica meat is suitable to produce functional foods based on the abudance of PUFA. |
| Keywords: | meat powder of Achatina fulica fatty acid organic solvent extraction gas chromatog-raphy-mass spectrometry |
