| 摘 要： | 为探究黑斑原肌肉营养成分,合理开发和保护利用黑斑原种质资源,分析采自西藏自治区日喀则市昂仁县境内(N 29°27′58.72″,E 86°54′36.06″)体质量为(158.92±24.10) g的黑斑原肌肉脂肪酸和无机盐组成成分。试验结果显示,黑斑原肌肉(鲜样)中含有16种脂肪酸,其中总饱和脂肪酸8种,总量为1015.7 mg/kg,单不饱和脂肪酸2种,总量为494.4 mg/kg,多不饱和脂肪酸6种,总量为1148.3 mg/kg,必需脂肪酸含量为108.37 mg/kg,二十碳五烯酸和二十二碳六烯酸含量为960.08 mg/kg。黑斑原肌肉的致动脉粥样硬化指数和血栓形成指数分别为0.40和1.18。黑斑原肌肉中共检出无机盐元素19种,其中K含量最高,为4061.23 mg/kg,V含量最低,为0.01 mg/kg,其中Ca∶P为1∶164,Na∶K为0.33∶1。对黑斑原肌肉中部分无机盐元素进行了风险评估,Zn元素风险指数最大,最大风险指数为16.13%~39.53%,Se元素的风险指数最小,最大风险指数为0.02%~0.03%,所评估的几种无机盐元素风险指数均在安全范围之内。综上,黑斑原肌肉中多不饱和脂肪酸含量丰富,无机盐元素含量丰富,具有较高的食用和保健价值。

| Abstract: | Compositions of fatty acids and minerals in muscles were analyzed in 10 samples of blackspot sisord catfish Glyptosternum maculaturm with body weight of(158.92±24.10)g collected from the territory of Ngamring County,XigazêCity(N 29°27′58.72″,E 86°54′36.06″),Xizang Autonomous Region in order to explore the nutritional composition of the muscle and to develop and protect the germplasm resources of blackspot sisord catfish.The results showed that there were 16 fatty acids in muscle including 8 saturated fatty acids(SFA),2 monounsaturated fatty acids(MUFA),and 6 polyunsaturated fatty acids(PUFA),with total content of 1015.7 mg/kg in SFA,494.4 mg/kg in MUFA and 1148.3 mg/kg in PUFA,and the total content of 108.37 mg/kg in essential fatty acid and 960.08 mg/kg in eicosapentaenoate(EPA)+docosahexaenoate(DHA).There were atherogenic index(IA)of 0.41,thrombosis index(IT)of 1.18,and 19 mineral elements in muscle of blackspot sisord catfish,with the maximal content of K(4061.23 mg/kg)and the minimal content(0.01 mg/kg)of vanadium(V)in muscle,with the value of Ca∶P=1∶164,and the value of Na∶K=0.33∶1.The risk evaluation of some minerals in muscle of blackspot sisord catfish revealed that the maximal risk index was Zn with the risk index from 16.13%to 39.53%and the minimal one Se with the risk index from 0.02%to 0.03%,indicating that all of the risk indices evaluated were within the safe rang.The findings indicated that there were abundant PUFA and abundant minerals in muscle of blackspot sisord catfish,which has higher edible and health value. |
