摘 要:为评定不同体重长白山野猪的肌肉营养成分,采集(80±5)kg和(100±5)kg体重的长白山野猪背最长肌,分别利用甲醇提取法和气相色谱法测定肌内脂肪含量和脂肪酸组成情况,比较了80 kg和100 kg体重的长白山野猪肌内脂肪和脂肪酸组成情况。结果表明:高体重长白山野猪肌内脂肪含量显著高于低体重个体(P<0.05),游离水含量显著低于低体重个体(P<0.05),肉豆蔻酸、棕榈酸相对含量极显著低于低体重个体(P<0.01),而亚油酸、多不饱和脂肪酸相对含量/饱和脂肪酸相对含量极显著高于低体重个体(P<0.01);高体重个体鲜肉中棕榈油酸、亚油酸、不饱和脂肪酸、多不饱和脂肪酸含量/饱和脂肪酸含量比值极显著高于低体重个体(P<0.01),单不饱和脂肪酸含量、不饱和脂肪酸含量/饱和脂肪酸含量比值显著高于低体重个体(P<0.05)。上述结果说明:屠宰体重对长白山野猪肌内脂肪酸含量具有显著影响。In order to evaluate the muscle nutritive composition in Mount Changbai boar, the contents of intramuscular fat and fatty acids were measured by methanol extraction and gas chromatography and compared between high body weight boar (100±5)kg and low body weight boar (80±5)kg. The results showed that the intramuscular fat contents of high body weight boar were significantly higher than that of low body weight boar (P 〈 0.05), but the free wa- ter contents of high body weight boar were significantly lower (P 〈 0.05). In the high body weight boars, the relative contents of myristic acid and palmitic acid were very significantly lower (P 〈 0.01), but the linoleic acid, the ratio of polyunsaturated fatty acid and saturated fatty acid were very significantly higher (P 〈 0.01). In the fresh pork, the contents of palmitoleic acid, linoleic acid, unsaturated fatty acid and the ratio of polyunsaturated fatty acid and satu- rated fatty acid were very significantly higher than that of the low body weight boar (P 〈 0.01), and the contents of monounsaturated fatty acid, the ratio of unsaturated fatty acid and saturated fatty acid were significantly higher than that of the low body weight boar (P 〈 0.05). In conclusion, the slaughter weight of Mount Changbai boar had significant effect on the contents of muscle fatty acids.
