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. |
