思南黄牛肉质营养特性研究

Research on meat nutritive property of sinan yellow cattle

试验选用5头思南黄牛青年公牛,对其常规营养成分、钙、磷及氨基酸和脂肪酸进行了测定。结果表明:鲜肉的蛋白质含量为(22.95±0.27)%,脂肪含量为(4.94±2.73)%,必需氨基酸与氨基酸总量(EAA/TAA)的比值为42.50%(未计色氨酸);不饱和脂肪酸(UFA)占总脂肪酸(TFA)的比例为46.30%。思南黄牛肉富含蛋白质与必需氨基酸,脂肪含量适宜,肉质柔软而不腻、易消化、营养价值高,是优质的膳食肉资源。

Five youth bulls of Sinan yellow cattle were slaughtered to ascertain the meat nutritive property by analysizing their meat general composition, calcium, phosphorus, energy, fatty acids and amino acids.The findings indicate that the contents of protein and fat are 22.95%, 4.94% based on fresh sample, respectively. The ratio of unsaturated fatty acid （UFA） to total fatty acids （TFA） is 42.50%, and the ratio of essential amino acid to total amino acid （EAA/TAA） is 46.30% （tryptophan excepted）. Therefore, the beef of Sinan yellow cattle is a high quality diet meat resource with rich protein and essential amino acids, appropriate fat, high nutritive value, pliability and non-greasy, and easy to be digested.
