高原鼢鼠肉营养成分分析及评价

Analysis and Evaluation on Nutritional Composition in Muscle of Myospalax baileyi

通过对高原鼢鼠(Myospalax baileyi)肉质进行营养成分的分析,评价其营养价值。测定了高原鼢鼠肉的水分、灰分、蛋白质、粗脂肪、微量元素、脂肪酸、氨基酸与维生素的含量。结果表明,高原鼢鼠肉中含丰富的蛋白质(18.7%)、氨基酸种类齐全(含17种氨基酸,8种人体必需氨基酸俱全)、脂肪酸以不饱和脂肪酸为主(占总脂肪酸的64.14%)、VE含量高,并含有一般动物肉中没有的VC,含有多种微量元素,微量元素含量具有明显的高K低Na等特点,符合现代营养保健趋势,可作为低钠营养保健品资源开发。

In this paper, the muscle nutrition compositions of Myospalax baileyi were analyzed and the nutrition values were evaluated. The content of water, ash, protein, coarse fat, trace elements, fatty acid, amino acid and vitamin were also determined. The results show that, in the flesh of Myospalax baileyi, proteins are highly up to 18.7%, various amino acids are included and unsaturated fatty acids accounts for 64.1% in the whole fatty acids, and Vit E content is very high. Exceptionally, Vit C （no traces in the fleshes of many other animals） and many kinds of trace elements are abundant in the fleshes of Myospalax baileyi with the characterization of high potassium content and low sodium content, which is accord to the trend of modern nutrition and health care and would have the potential to be used for resource exploitation of nutrition and health protection substances with low sodium content.
