摘要：

应用模糊识别法和氨基酸比值系数法，分别以鸡蛋蛋白质为标准蛋白，以WHO/FAO氨基酸参考模式为评价标准，对晋谷9个优良品种的蛋白质营养价值进行了全面评价。结果表明：晋谷蛋白质含量为10.37%~11.84%。晋谷13号和晋谷30号蛋白中氨基酸总量最高,为991.11mg/g~989.56 mg/g。九个晋谷品种蛋白中的氨基酸种类齐全，必需氨基酸占氨基酸总量的39%～40%，第一限制氨基酸是赖氨酸，氨基酸比值系数分（SRC）为65.47~67.64。谷子是营养价值很高的植物蛋白。

Abstract:

Using the egg protein as a standard protein and WHO/FAO reference model of essential amino acid (EAA) as an appraisal criterion, the nutritional value of the proteins in the nine cereals were evaluated by fuzzy pattern recognition and ratio coefficient of amino acid (AA). The results showed that the protein contents of nine cereals ranged from10.37% to 11.84% in the dried samples. The total amino acid contents of Jingu 13 and Jingu 30 were higher, which were 991.11 mg/g and 989.56mg/g .The cereals were rich in all kinds of AA and EAA took up39%~40% of total EAA. The first limiting AA was Lys. Score of ratio coefficient of AA （SRC）was 65.47~67.64.The cereal considered as a fine plant proteins’ source that can be exploited and used.
