60份国内外藜麦材料子粒的品质性状分析

研究藜麦子粒的品质性状,可以为藜麦育种、加工及消费提供参考。本研究对4份国内和56份国外藜麦材料子粒的品质性状进行了分析,结果表明60份藜麦材料子粒的千粒重、灰分、蛋白质、淀粉、脂肪、粗纤维、总黄酮和总多酚平均含量分别为4.23 g、2.28%、14.03%、57.71%、6.53%、2.46%、1.83 mg/g和1.49 mg/g。国内藜麦材料的灰分、蛋白质和总多酚平均含量较高,分别为3.47%、14.92%和1.78 mg/g;秘鲁藜麦材料的脂肪、粗纤维和总黄酮平均含量较高,分别为6.69%、2.66%和2.03 mg/g;美国藜麦材料的淀粉平均含量较高,为59.91%;玻利维亚藜麦材料的千粒重较高,为4.32 g;不同子粒颜色藜麦材料之间的品质存在差异,黑色藜麦材料的蛋白质含量较高,白色和红色藜麦材料的淀粉含量较高,红色和黑色藜麦材料的粗纤维、总黄酮和总多酚含量较高。

Quality Characters Analysis of the Seed of 60 Domestic and Overseas Quinoa Accessions

Research on the quality characters of quinoa seed could be useful in quinoa breeding, processing, and consumption. The quality characters of 4 domestic and 56 overseas quinoa accessions were analyzed. The results showed that the average contents of thousand seed weight, ash, protein, starch, fat, crude fiber, total flavones, and total polyphenols in 60 quinoa accessions were 4.23 g, 2.28%, 14.03%, 57.71%, 6.53%, 2.46%, 1.83 mg/g, and 1.49 mg/g, respectively. Domestic quinoa accessions had higher content of ash 3.47%, protein 14.92%, and total polyphenols 1.78 mg/g. Peruvian quinoa accessions had higher content of fat 6.69%, crude fiber 2.66%, and total flavones 2.03 mg/g. American quinoa accessions had higher content of starch 59.91%. Bolivian quinoa accessions had higher content of thousand seed weight 4.32 g. Quinoa with different seed colors showed different quality. Black quinoa had higher content of protein, white and red quinoa had higher content of starch, and red and black quinoa had higher content of crude fiber, total flavones, and total polyphenols.
