甘南地区河曲马肉营养价值的研究

本文研究了河曲马肉的营养成分及营养价值。该品种肉蛋白质含量(22.87％)较高,脂肪含量(4.96％)较低。人类所需的各种必需氨基酸总量占全部氨基酸总量的12.67％。各种必需氨基酸的含量与人需要的“理想蛋白质”中的建议标准量相比较,仅缬氨酸(46.6mg/g蛋白质)略低于标准(50mg/g蛋白质)外,其他各种均不同程度地超过标准量。其中赖氨酸量为建议标准量的1.52倍。说明其肉蛋白质的质量较优。马脂中的多不饱和脂肪酸占脂肪酸总量的22.64％,多不饱和脂肪酸:饱和脂肪酸(P/S比)为0.6∶1,这是表明食物营养价值较高的另一主要方面。本试验测定出河曲马肉的胆固醇含量为101mg/100g鲜肉,总维生素C含量为20.20mg/100g鲜肉。
