摘要: 为了评价蒙古牛肉的肉质特性与营养价值,本研究选择6头4岁的常年放牧在库布齐沙漠的蒙古阉牛,进行了牛肉常规营养成分及氨基酸含量的测定分析。结果显示,牛肉中水分、粗蛋白质、粗脂肪、粗灰分、钙和磷含量分别为68.21%、22.60%、6.49%、2.69%、0.58%和0.55%;牛肉中总氨基酸含量为24.297 g/100 g,必需氨基酸含量为10.265 g/100 g,必需氨基酸的构成比例符合并超过FAO/WHO公布的标准。必需氨基酸占总氨基酸含量的42.25%,必需氨基酸与非必需氨基酸比值为73.15%。功能性氨基酸中,鲜味氨基酸和甜鲜味氨基酸含量为总氨基酸的46.891%。另外,必需氨基酸中除缬氨酸之外其他氨基酸全部优于FAO/WHO规定的理想蛋白质模式,缬氨酸含量达到理想蛋白质的83.972%。因此,从牛肉的常规养分含量和氨基酸的营养价值方面来评定,蒙古牛肉属于营养全面的优质蛋白质食物。

Abstract: In order to evaluate the Mongolia muscle characteristics and nutritional value, six Mongolia bullocks aged 4 years grazed in Kubuqi desert were chosen to analyze the regular nutritional components and amino acid contents of Mongolia muscle.The results showed that the contents of water, crude protein (CP), crude fat (EE), crude ash (ash), calcium and phosphorus of Mongolia muscle (fresh) were 68.21%, 22.60%, 6.49%, 2.69%, 0.58% and 0.55%, respectively.A total amino acid (TAA) content of beef was 24.297 g/100 g, essential amino acid content was 10.265 g/100 g, the proportion of essential amino acid justified and exceeded the FAO/WHO standard.The ratio of essential amino acid and total amino acid contents (EAA/TAA) was 42.25%, the ratio of essential amino acid and the non-essential amino acid (EAA/NEAA) was 73.15%.In functional amino acid, the content of palatable taste amino acid and sweet flavor amino acid in total amino acid was 46.891%.In addition to valine, essential amino acid contents of Mongolia muscle were superior to ideal protein of FAO/WHO standard, the percentage of valine reached 83.972% in ideal protein.These results indicated that Mongolia muscle belonged to the comprehensive nutrition and high quality protein food on the evaluation of the regular nutrient content and the amino acid content of beef.
