马鹿亚种间杂交后代背最长肌脂肪酸的分析研究

摘要

Gas chromatography was used for analyzing fatty acids extracted from longissimus dorsi muscle of three subspecies hybrid offspring of cervus elaphus： Tian - shah stock （ C. elaphus songaricus）, Tian - shan x Qing - hal crossbred and Tian -shan x Qing - hai x Talimu crossbred. The result indicated that： （ 1 ） Saturated fatty acids took the highest percentage of the fatty acids composition from all the three cervus elaphus mentioned above. Palmitic acid was the major composition; （2） The nutritional value of the rne~t of Tian - shan x Qing - hai crossbred was higher than that of Tian -shan and Tian -shan x Qing - hai ~ Talimu, it can offer nutritional meat which meet food standard by cress - breeding; （3） Fatty acids with odd number carbon atom showed anticancer activity were also found in the meat from all three cervus elaphus. The results of this article could provide theoretical evidence for the development of functional food from meat of cervus elaphus.%采用气相色谱技术对马鹿不同亚种间杂交后代——天山马鹿、天青二元杂交马鹿和天青塔三元杂交马鹿背最长肌中的20种脂肪酸进行分析研究，结果表明：三种马鹿背最长肌脂肪酸组成及含量各有特点，但是饱和脂肪酸含量均最高，棕榈酸为主要组成成分。都含有一定量的具有抗癌活性的奇数碳原子脂肪酸，含量分别为：3．73％、7．28％和0．71％，该结果为马鹿内在功能食品领域的发展提供了理论依据。从营养角度出发，天青二元杂交马鹿肉比天山马鹿和天青塔三元杂交马鹿具有更高的营养价值，可以通过杂交育种来选育营养价值更符合膳食标准的健康马鹿肉品原料。
