商城肥鲵的含肉率及其肌肉生化成分分析 总被引:5,自引:0,他引:5
商城肥鲵(Pachyhynobius shangchengensis)属有尾目(Caudata)小鲵科(Hynobidae)肥鲵属(Pachyhynobius),是有尾目中最原始的一个类群,分布区极狭窄,仅大别山商城、金寨、霍山、英山有分布。该研究通过商城肥鲵的含肉率测定及其肌肉生化成分分析,对其品质、营养价值作出初步评定。 相似文献

[目的]为商城肥鲵的生物学研究和两栖类血液生理比较细胞学研究提供基础资料。[方法]采集商城肥鲵的血液,用常规法制成血涂片。用姬姆萨染液染色后,对商城肥鲵血细胞形态进行观察,并对其血液进行检验分析。[结果]在商城肥鲵血涂片中可鉴定出红细胞、单核细胞、淋巴细胞、血栓细胞、嗜酸性粒细胞、嗜碱性粒细胞和嗜中性粒细胞。红细胞数量较多,长椭圆形,具圆核。白细胞数量少,圆形,其中淋巴细胞和单核细胞含量最高。商城肥鲵的红细胞平均数为3.2×105/mm3,白细胞平均数为9.1×104/mm3,血红蛋白含量为48 g/L,凝血时间为6.2 min。[结论]商城肥鲵红细胞大小平均为15.5μm×9.6μm,比东北小鲵小,而红细胞数量却比东北小鲵多,这可能与其在两栖类中所处位置有关,并与其生态习性相适应。 相似文献

[目的]研究商城肥鲵的含肉率及其肌肉生化成分,为商城肥鲵营养生理生态研究提供基础资料。[方法]用生化分析方法测定了商城肥鲵的含肉率及其肌肉生化成分。[结果]商城肥鲵的含肉率雌性为54.93%、雄性为55.84%,肌肉含蛋白质雌性为15.44%、雄性为15.67%,总糖雌性为1.70%、雄性为1.89%,脂肪雌性为0.68%、雄性为0.53%。商城肥鲵肌肉中18种氨基酸总量为12.72%(鲜重),其中8种必需氨基酸量为4.68%;必需氨基酸指数(EAAI)为72.68,限制性氨基酸为缬氨酸。商城肥鲵肌肉中包含11类脂肪酸,不饱和脂肪酸含量(80.02%)远大于饱和脂肪酸含量(19.98%)。[结论]商城肥鲵属于低脂肪高蛋白的营养类型,是一种可贵的野生自然资源。 相似文献

[Objective] The ratio of flesh content and biochemical compositions in muscles of Pachyhynobius shangchengensis were researched in this experiment to provide basic referrences for studying nutritive physiological ecology of Pachyhynobius shangchengensis.[Method]The biochemical analytic method was used to detect the ratio of flesh content and biochemical compositions in muscle of Pachyhynobius shangchengensis.[Result]The ratio of flesh contents of female and male Pachyhynobius shangchengensis were 54.93% and 55.84% respectively.The contents of protein,total saccharides and fatty acid of female Pachyhynobius shangchengensis were 15.44%,1.70% and 0.68% respectively,while the same contents of male Pachyhynobius shangchengensis were 15.67%,1.89% and 0.53% respectively.The total content of 18 kinds of amino acids was 12.72%(the proportion in fresh weight),among which the content of 8 kinds of essential amino acids was 4.68%.The essential amino acids index(EAAI)was 72.68 and limiting amino acids was valine.There were 11 kinds of fatty acids in muscles of Pachyhynobius shangchengensis,among which the content of unsaturated fatty acids(80.02%)was higher than that of saturated fatty acids(19.98%).[Conclusion] Pachyhynobius shangchengensis was a kind of valuable natural resource belonging to the nutritious type of low fat content and high protein content. 相似文献
