摘　　要：目的分析安徽省北方地区某市7种杂豆中的营养成分含量,并对其进行营养评价,以了解杂豆的营养价值。方法按照随机抽样的方法采集该市不同农贸市场与超市7种杂豆样品;采用氨基酸自动分析仪测定氨基酸含量,使用氨基酸评分与氨基酸指数法对其进行营养评价;采用电感耦合等离子体质谱法测定矿物质含量,索氏提取测定脂肪含量,蛋白质分析仪测定蛋白质含量,高效液相色谱法测定维生素含量,并用营养质量指数法进行评价。结果 7种杂豆均含有18种氨基酸、9种矿物质元素、蛋白质与维生素E。必需氨基酸与总氨基酸比值在44.15%~47.07%之间,必需氨基酸与非必需氨基酸比值在79.07%~88.93%之间,氨基酸指数(EAAI)范围为73.72~95.53;K/Na比值范围为32.8~1719,除钙与钠外,磷、钾、镁、铁、锌、铜、锰的营养质量指数(INQ)值均大于1;蛋白质含量为20.10~43.21 g/100 g,维生素E含量为3.73~22.50 mg/100g,其中青豆与黑豆维生素E含量最高,分别为22.50 mg/100 g与22.10 mg/100 g。结论所采集的7种杂豆氨基酸、蛋白质与维生素含量丰富,符合理想蛋白质标准,矿物质含量满足人体需要,均为高钾低钠型食物,平衡人体营养具有重要意义。Objective To analyze the nutritional content of 7 kinds of beans in the north city,Anhui Province,and to evaluate their nutritional value.Methods The samples were randomly collected in the different markets and supermarkets in the city.Amino acids were determined by amino acid automatic analyzer and the nutritional values were evaluated by amino acid score and amino acid index method.Mineral contents were determined by inductively coupled plasma mass spectrometry(ICP-MS),and the fat was determined by soxhlet extraction,the protein was determined by protein analyzer,the vitamins were determined by high performance liquid chromatography,which these nutritional compositions were evaluated using the INQ methods.Results The results showed that the 7 kinds of miscellaneous beans contained 18 kinds of amino acids,9 kinds of mineral elements,protein and vitamin E.The ratio of essential amino acids to total amino acids was between 44.15% and 47.07%,the ratio of essential amino acids to non-essential amino acids was between 79.07% and 88.93%,and the amino acid index(EAAI) ranged from 73.72 to 95.53.The K/Na ratio ranges from 32.8 to 1719.The INQ values of phosphorus,potassium,magnesium,iron,zinc,copper and manganese are all greater than 1,with the exception of calcium and sodium.The protein content was between 20.10 g/100 gand 43.21 g/100 g,and the vitamin E content was between 3.73 mg/100 g and 22.50 mg/100 g.The vitamin E of green beans and black beans were the highest,and the values were 22.50 mg/100 g and 22.10 mg/100 g respectively.Conclusion The above results showed that the amino acids,proteins and vitamins in 7 kinds of beans were rich,which can meet the ideal protein standard.Meanwhile,all of them were high potassium and low sodium foods,and it was of great significance to balance human nutrition.
