摘要:

用常规方法测定甘南藏族自治州牦牛肉中肉质特性和营养成分。结果表明:与当地黄牛肉(对照组)比较,牦牛肉(实验组)干物质高23.19%、蛋白质高6.14%、灰分高12.5%、脂肪低13.54%、氨基酸总量(TAA)高13.38%、必需氨基酸(EAA)高10.88%,必需氨基酸与非必需氨基酸(EAA/NEAA)的比值为67.94%。甘南牦牛肉具有色泽深红、系水力高、熟肉率高、蛋白高、脂肪低、氨基酸种类齐全等特点。

关键词: 甘南, 牦牛, 肉质特性, 氨基酸

Abstract:

The meat quality related indexes and nutrient content in yak meat from Gannan were studied, and compared with the meat of yellow cattle.
