| 摘 要： | 为了比较不同品种（系）甜菜的氨基酸组分及含量，探讨其营养价值，本研究以14 个品种（系）甜菜块根为研究对象，采用主成分分析法对其氨基酸组分进行分析综合评价。结果表明，甜菜块根中均含有18 种常见氨基酸，其中人体必需的7 种氨基酸，接近WHO/FAO推荐必需氨基酸组成比例，达到理想的蛋白质标准，并且其含量高于常见的果蔬，具有较高的氨基酸营养价值。通过主成分分析法，从检出的18 种氨基酸中提取了3 个主成分，建立了综合评价模型，综合评价氨基酸含量结果表明‘红霞’、‘BETA807’、‘红饲料’营养品质较好。主成分分析法可以作为评价不同品种（系）甜菜氨基酸营养的一种可行方法。

Principal Component Analysis and Nutrition Comprehensive Evaluation of Amino Acid in Different Sugar Beet Varieties |
| |
| Abstract: | The objectives of the study were to compare amino acid composition and content, and discuss the nutritional values of different sugar beet varieties. Sugar beet roots of 14 varieties were chosen to measure their amino acid and obtain the comprehensive evaluation on nutritional quality by using principal component analysis. The results indicated that sugar beet roots had 18 common amino acids, including 7 human body essential amino acids, and the composition was close to the recommended level of WHO/FAO. The amino acid content of sugar beet root achieved the ideal protein standard and higher than that of common fruits and vegetables, had high nutritional value. Three principal components were classified from 18 amino acids with principal component analysis. And a comprehensive evaluation model was established. Comprehensive
evaluation of the amino acid content showed that‘Hong Xia’,‘BETA 807’,‘Hong Si liao’had better quality. Principal component analysis could be a feasible method to evaluate amino acid nutrition of sugar beet. |
