Amino acids are valuable nutrients, responsible for a variety of tasks in the human body. A favourable amino acid profile in gluten-free crops, such as millet, can thus be beneficial for human health, which is why 35 proso millet (Panicum miliaceum L.) samples, comprising 23 whole and 12 dehulled, were investigated regarding their amino acid profiles and compositions using acidic hydrolysis and ion-exchange chromatography with ninhydrin derivatization and subsequent detection with photometry. Results for amino acid compositions were compared with gluten-containing wheat and other gluten-free cereals. Furthermore, gained values were put in contrast to estimated essential amino acid requirements for adult humans. The study was able to show that cultivars of proso millet differ and that dehulling does not significantly influence the amino acid compositions. Furthermore, the results display that Panicum miliaceum L. holds more essential amino acids than other gluten-free grains and exhibits high amounts of leucine and alanine. The methionine content differs greatly between samples, which means that choosing certain cultivars is important to ensure a high content. The most abundant amino acids in proso millet grains are glutamic acid/glutamine (2.13 ± 0.34 g per 100 g), alanine (1.06 ± 0.18 g per 100 g) and leucine (1.36 ± 0.24 g per 100 g).

Panicum miliaceum L 不同品种的氨基酸谱和组成。

氨基酸是宝贵的营养素，负责人体内的各种任务。因此，无麸质作物（如小米）中有利的氨基酸谱对人类健康有益，这就是为什么对 35 个原谷子 (Panicum miliaceum L.) 样品（包括 23 个全谷和 12 个去壳）的氨基酸进行研究的原因使用酸性水解和离子交换色谱法与茚三酮衍生化和随后用光度法检测的分布和组成。氨基酸组成的结果与含麸质小麦和其他无麸质谷物进行了比较。此外，将获得的值与估计的成年人必需氨基酸需求量形成对比。该研究能够表明 proso 小米的品种不同，脱壳不会显着影响氨基酸组成。此外，结果显示 Panicum miliaceum L. 比其他无麸质谷物含有更多的必需氨基酸，并显示出大量的亮氨酸和丙氨酸。样品之间的蛋氨酸含量差异很大，这意味着选择某些品种对于确保高含量很重要。proso小米谷物中最丰富的氨基酸是谷氨酸/谷氨酰胺（2.13 ± 0.34 g/100 g）、丙氨酸（1.06 ± 0.18 g/100 g）和亮氨酸（1.36 ± 0.24 g/100 g）。样品之间的蛋氨酸含量差异很大，这意味着选择某些品种对于确保高含量很重要。proso小米谷物中最丰富的氨基酸是谷氨酸/谷氨酰胺（2.13 ± 0.34 g/100 g）、丙氨酸（1.06 ± 0.18 g/100 g）和亮氨酸（1.36 ± 0.24 g/100 g）。样品之间的蛋氨酸含量差异很大，这意味着选择某些品种对于确保高含量很重要。proso小米谷物中最丰富的氨基酸是谷氨酸/谷氨酰胺（2.13 ± 0.34 g/100 g）、丙氨酸（1.06 ± 0.18 g/100 g）和亮氨酸（1.36 ± 0.24 g/100 g）。
