中国菰米的营养成分及其蛋白质特性的研究

为了开发利用我国具有悠久历史的菰米资源，了解中国菰米的营养价值。我们从中国华东地区的骆马湖、宝应湖、洪泽湖、微山湖和东太湖采收野生菰米，同时取微山湖附近的大米作对照，进行了一般营养成分、无机盐、微量元素和氨基酸以及蛋白功效比值（ＰＥＲ）的分析测定。结果显示中国菰米有较高的营养素含量。以每１００克样品计，含蛋白质１３．２ｇ、ＶＢ、０．５９ｍｇ、ＶＢ２０．１１ｍｇ、ＶＥ０．２９ｍｇ和锌１．６０ｍｇ、铁

Study on nutrition composition and protein quality of a Chinese wild rice

In order to exploit and develop the resource of a kind of Chinese wild rice[ Zinania Lalifolia (Griseb)Turcz],the nutrition values of the Chinese wild rice from Luoma,Baoying,Hongze,Weishan and Tai lake were analyzed.The nutrients of Chinese wild rice per 100g samples were protein 13 2g,vitamin B 1 0 59mg,vitamin B 2 0 07mg,vitamin E 0 29mg,zinc 1 60 mg,iron 2 69mg,and they were higher than those of white rice.The amino acid score of Chinese wild rice was 84,the first limiting amino acid was threonine,and the protein efficiency ratio(PER) was 2 75.These data showed that the Chinese wild rice was a good food resource with higher nutrition value,therefore,the ancient and novel food resource might be used in Chinese diet as the North American wild rice that was used in American diet.
