This study aimed to prepare soybean dregs dietary fibre (DF) using physically assisted chemical (KHMSO) modification and study its structure, function and vitro simulation experiments. The soluble dietary fibre (SDF) content in KHMSO increased and insoluble dietary fibre (IDF) content decreased. The modified DF surface becomes irregular and rough, and the results of XPS fitting indicated that the DF structure had different peak-splitting groups. The KHMSO-treated group had the lowest digestion rate in gastric fluid and the highest digestibility in intestine fluid. The OD of fecal cultures was increased to 0.915, and the increased abundance of microbiota was associated with the metabolism of SCFAs, such as Lachnospiraceae, as well as the higher n-butyric acid in the KHMSO-treated group compared to the other groups and lower than the inulin, suggesting KHMSO might enhance the production of functional foods aimed at promoting intestinal health.
本研究旨在使用物理辅助化学（KHMSO）改性法制备大豆豆渣膳食纤维（DF），并研究其结构、功能和体外模拟实验。KHMSO 增加了可溶性膳食纤维（SDF）的含量，降低了不溶性膳食纤维（IDF）的含量。改性 DF 的表面变得不规则且粗糙，XPS 拟合结果表明，DF 结构具有不同的分峰基团。在胃液中，KHMSO 处理组的消化率最低，在肠液中的消化率最高。粪便培养物的 OD 值增加到 0.915，增加的微生物群落丰度与 SCFAs 的代谢有关，例如lachnospiraceae，以及 KHMSO 处理组的丁酸含量高于其他组，低于菊粉，这表明 KHMSO 可能增强旨在促进肠道健康的功能性食品的生产。
