[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 100 g samples were protein 13.2 g, vitamin B1 0.59 mg, vitamin B2 0.07 mg, vitamin E 0.29 mg, zinc 1.60 mg, iron 2.69 mg, 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.
