Abstract: The nutrients such as moisture,protein,fat and carbohydrate in foxtail millet were determined with ten kinds of Shanxi main varieties of foxtail millet as raw materials. The contents of amino acids were determined by liquid chromatography,and the main nutrients and amino acid contents of foxtail millet were analyzed and evaluated through the fuzzy recognition method and amino acid ratio coefficient method,as well as the whole egg protein model and the FAO/WHO model. The results showed that there were differences in nutrient content of different varieties of foxtail millet. The variation of protein ranged from 11.43% to 13.72%,the fat range was between 3.75% and 5.34%,and the range of carbohydrates was between 81.30% and 84.60%. The total amino acid content ranged from 9.04% to 11.34%,and the moisture content ranged from 10.35% to 12.37%. The 10 kinds of foxtail millet were rich in 17 kinds of amino acids,among which the essential amino acids were abundant,and the levels of glutamate and leucine were especially high. The RAA and RC of five amino acids of Fenxuan 3 were about 1 with the EAAI 0.80 close to 1,indicating that it was a good protein source with high nutritional value and utilization. Jingu 21 had high umami amino acids content and strong flavor,it was easier to be welcomed and loved by consumers.
