The diversity in human diets that can be reached by proper use of different crops and varieties, including some underutilized ones, is a potentially powerful strategy to ensure food security and prevent serious health problems caused by current diets that are often not fulfilling nutritional requirements. In the framework of this research, the content of tocopherols and tocotrienols, thiamine, riboflavin, pyridoxine, and superoxide dismutase in nine varieties of quinoa, both colored and nonpigmented, obtained from 4 different countries, was investigated and compared to the content of the same vitamins and antioxidants in barley and wheat, both colored and nonpigmented, cultivated in the same experimental field. The aim of this work was to create a crop diversity strategy and encourage the consumption of underutilized crops to ensure that the human diet fulfills nutritional requirements. The contents of vitamin B1, B2, B6, tocopherol, and tocotrienol isomers and superoxide dismutase were determined via HPLC; imaging techniques were used to evaluate the seed color. Quinoa grains had the greatest concentration of tocopherol isomers and activity, represented mainly by α-tocopherol and γ-tocopherol. Wheat and barley seeds had substantial concentrations of tocopherols and tocotrienols. The concentration of riboflavin was greater in barley and wheat than in quinoa, the concentrations of pyridoxine and thiamine were variety-dependent in all grains. Quinoa grains had greater concentration of superoxide dismutase compared to wheat and barley. The richness of each variety and crop should be recognized and used integrally to improve the diet quality. PRACTICAL APPLICATION Nutritional potential of crops was evaluated from the viewpoint of selected vitamins and antioxidants to create a well-balanced diet. Combined use of both traditional (wheat, barley) and underutilized crops (quinoa) is recommended. HPLC methods and image analysis were successfully used as viable tools for food quality determination.

藜麦、大麦和小麦的有色和无色素品种中精选维生素和抗氧化剂的含量

通过适当使用不同的作物和品种（包括一些未充分利用的作物）可以实现人类饮食的多样性，这是确保粮食安全和预防由当前通常不能满足营养需求的饮食引起的严重健康问题的潜在有力策略。在本研究的框架内，对来自 4 个不同国家的 9 个有色和无色素藜麦品种中的生育酚和生育三烯酚、硫胺素、核黄素、吡哆醇和超氧化物歧化酶的含量进行了调查，并与相同的含量进行了比较。大麦和小麦中的维生素和抗氧化剂，无论是有色的还是无色的，都在同一试验田中种植。这项工作的目的是制定作物多样性战略并鼓励消费未充分利用的作物，以确保人类饮食满足营养需求。高效液相色谱法测定维生素B1、B2、B6、生育酚、生育三烯酚异构体和超氧化物歧化酶的含量；成像技术用于评估种子颜色。藜麦籽粒生育酚异构体浓度最高，活性最高，主要以α-生育酚和γ-生育酚为代表。小麦和大麦种子含有大量的生育酚和生育三烯酚。大麦和小麦中核黄素的浓度高于藜麦，吡哆醇和硫胺素的浓度在所有谷物中呈品种依赖性。与小麦和大麦相比，藜麦谷物的超氧化物歧化酶浓度更高。应认识到每个品种和作物的丰富性，并加以综合利用，以提高饮食质量。实际应用 从选择的维生素和抗氧化剂的角度评估作物的营养潜力，以创造均衡的饮食。建议结合使用传统作物（小麦、大麦）和未充分利用的作物（藜麦）。HPLC 方法和图像分析成功地用作食品质量测定的可行工具。
