中文摘要:

      目的 探究不同产地小麦麸皮的主要活性成分含量差异, 为小麦麸皮的后续研究提供理论基础。方法 以国内不同产地30个小麦麸皮样品为研究对象, 测定其甜菜碱、多酚、烷基间苯二酚(alkylresorcinols, ARs)的含量, 利用聚类分析法对不同产地小麦麸皮活性成分的含量进行评价。结果 30个小麦麸皮样品中, 甜菜碱含量范围在(10.82±0.09)~(27.28±0.50) μg/g; 多酚含量范围在(32354.79±26.44)~(73068.27±15.85) μg/g; 总烷基间苯二酚(总ARs)含量范围在(511.05±1.02)~(2186.11±3.17) μg/g。聚类分析法将所有样品分为3类, 其中5号(新疆奇台县)被单独聚为一类, 其小麦麸皮中活性成分含量较为优异。结论 通过聚类分析得出5号样品 (新疆奇台县)的小麦麸皮中活性成分含量相对较高, 该样品具有较大潜力, 可进一步开发相关功能性食品。

英文摘要:

      Objective To explore the differences in the content of the main active ingredients of wheat bran from different origins, and to provide a theoretical basis for the subsequent research on wheat bran. Methods Thirty wheat bran samples from different origins in China were used to determine the contents of betaine, polyphenols, and alkylresorcinols (ARs), and to evaluate the contents of active ingredient in wheat bran from different origins using cluster analysis. Results Among the 30 wheat bran samples, betaine content ranged from (10.82±0.09) to (27.28±0.50) μg/g; polyphenol content ranged from (32354.79±26.44) to (73068.27±15.85) μg/g of total alkyl resorcinols (total ARs) ranged from (511.05±1.02) to (2186.11±3.17) μg/g. Cluster analysis was used to classify all the samples into 3 categories, among which No.5 (Qitai County, Xinjiang) was clustered into a separate category, which had superior content of active ingredients in wheat bran. Conclusion Cluster analysis yielded a relatively high content of active ingredients in the wheat bran of sample No.5 (Qitai County, Xinjiang), which has a greater potential for further development of related functional foods.
