| Abstract: | The nutritional components of three different varieties of Dioscorea were analyzed, aiming to explore the advantages of glutinous Dioscorea and provide data support for the research on the nutritional value of glutinous Dioscorea. The contents of protein, starch, amino acids and mineral elements in Dioscorea were determined using corresponding scientific methods (Kjeldahl determination of nitrogen, acid hydrolysis, anthrone-sulfuric acid colorimetry, flame atomic absorption spectrometry). The results show that there are remarkable differences in the nutritional components of different Dioscorea varieties. Wencheng glutinous Dioscorea is rich in starch, reducing sugar, dietary fiber, β-carotene and available carbohydrates, with the content of 16.13%, 0.75%, 0.85%, 251.67 mg/100 g and 16.91%, respectively. Additionally, Wencheng glutinous Dioscorea is also rich in mineral elements and amino acids, especially for histidine and arginine. The content of total amino acids, essential amino acids and flavorful amino acids in Wencheng glutinous Dioscorea is 1.57%, 0.46%, and 0.57%, respectively. In summary, the starch content of Wencheng glutinous Dioscorea is significantly higher than that of the other two varieties of Dioscorea (Huaishan and Iron Stick Yam), resulting in better flavor with abundant amino acid, and it could be recommended as a high-quality variety as both vegetable and grain. |
