摘要
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质功效比值 (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 10 0克样品计 ,含蛋白质 13.2 g、VB1 0 .5 9mg、VB2 0 .11mg、VE0 .2 9mg和锌 1.6 0 mg、铁 2 .6 9mg等。中国菰米蛋白质的必需氨基酸丰富 ,结构合理 ,第一限制氨基酸是苏氨酸 ,其化学分高达 84,PER高达2 .75。这些结果表明 ,中国菰米是一种优良的野生食物资源 ,含有优质蛋白质 ,具有较高营养价值 ,亟待开发利用 ,应如北美野米一样 。
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.
