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 20.10g/100gand 43.21 g/100g,and the vitamin E content was between 3.73 mg/100g and 22.50 mg/100g.The vitamin E of green beans and black beans were the highest,and the values were 22.50 mg/100g and 22.10mg/100g 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.
