摘要
Quinoa (Chenopodium quinoa Willd.) is an ancient crop with perfect nutritional composition and antioxidants substances. However, the current research on the nutritional quality of quinoa is limited to a small number of varieties or a single origin. In this study, we aimed at providing a detailed evaluation of abundant nutrients of quinoa seeds from thirty varieties with different color in different origins, including soluble protein, soluble sugar, amino acid, vitamin, fatty acid and saponin. Results showed that there were significant differences in the contents of γ-aminobutyric acid (6.67-78.67 mg/100 g DW) and vitamin C (11.675-105.135 mg/100 g DW) in quinoa seeds. Here, we scored thirty quinoa seeds using a weighted average score system first time and identified four varieties, black quinoa JQ-00145, red quinoa JQ-00125 and two white quinoa JQ-00005/JQ-00077, with superior nutritional quality and oxidation resistance. The results of this study will provide theoretical guidance for consumption of quinoa.
