采用亚临界水法提取麸皮中可溶性膳食纤维，以麸皮中可溶性膳食纤维的得率为评价指标，通过中心组合设计（CCD）优化提取温度和提取时间，建立回归模型，进而得出亚临界水提取可溶性膳食纤维的最佳工艺条件为：提取压力15 MPa，提取温度230.10℃，提取时间26.79 min。经过实验验证，该条件下可溶性膳食纤维的得率高达45.34%。本研究将亚临界水萃取技术应用于麸皮中可溶性膳食纤维的提取，为亚临界水萃取技术在功能性多糖提取领域的研究提供了一定的理论基础。
採用亞臨界水法提取麩皮中可溶性膳食纖維，以麩皮中可溶性膳食纖維的得率為評價指標，通過中心組閤設計（CCD）優化提取溫度和提取時間，建立迴歸模型，進而得齣亞臨界水提取可溶性膳食纖維的最佳工藝條件為：提取壓力15 MPa，提取溫度230.10℃，提取時間26.79 min。經過實驗驗證，該條件下可溶性膳食纖維的得率高達45.34%。本研究將亞臨界水萃取技術應用于麩皮中可溶性膳食纖維的提取，為亞臨界水萃取技術在功能性多糖提取領域的研究提供瞭一定的理論基礎。

We discussed the process optimization about subcritical water extraction of soluble dietary fiber from wheat bran. Subcritical water was employed for extraction of soluble dietary fiber and the extraction temperature and time were optimized by central composite design (CCD) for the highest yield of soluble dietary fiber. The optimal subcritical water extraction temperature and time for wheat bran were 230.10℃and 26.79 min.With the optimal conditions, the yield of soluble dietary fiber up to 45.34%. In this study, subcritical water extraction technology was used for extraction of soluble dietary fiber from wheat bran for the first time, there may provide a theoretical foundation for the study of subcritical water extraction technique in the field of functional polysaccharide.
