摘　　要：以甘肃省永登县民乐乡黑大麦、白大麦为主要研究对象,采用国家标准方法,即灰化法、高锰酸钾滴定法、蒽酮比色法、索氏抽提法、凯氏定氮法等方法,测定黑大麦中水分、灰分、钙、磷、蛋白质、总糖、粗脂肪、淀粉等基本营养成分及纤维成分.本实验通过对比分析得出,黑大麦中灰分含量为2.06±0.04 g/100g,粗脂肪含量为1.66±0.42 g/100g,总糖含量为63.03±1.05 g/100g,粗纤维含量为6.12±0.34 g/100g,磷含量为371 mg/100g,分别比白大麦高出0.18%,0.22%,2.79%,1.47%和0.012%,相对于白大麦具有营养优越性.The progress conditions of the analysis of nutritional composition in black barley and white barley from Yongdeng County Gansu Province were investigated using the national standards including permanganate titration method, Kjeldahl method, Soxhlet extraction method and other national standard methods. The water, ash, calcium, phosphorus, protein, total reducing sugar, fat, fiber and other basic nutrients were determined. The results showed that the contents of the ash, fat, total reducing sugar, fiber and phosphorus in the black barley were 2.06 ± 0.04 g/100g, 1.66 ± 0.42 g/100g, 63.03 ± 1.05 g/100g, 6.12 ± 0.34 g/100g, 371 ± 5.58 rng/100g respectively, which were 0.18 % ,0.22 % ,2.79 %, 1.47 % and 0. 012 % larger than those in the white barley.
