摘要:

利用响应面法优化超声波辅助碱法提取杜仲籽粕可溶性膳食纤维的工艺条件。在单因素试验基础上,选取料液比、超声时间、提取温度为影响因素,以可溶性膳食纤维得率为响应值,应用Box-Behnken试验设计建立数学模型,进行响应面分析。结果表明:超声波辅助碱法提取杜仲籽粕可溶性膳食纤维的优化工艺条件为碱液质量浓度2.0g/100mL、料液比1:23(g/mL)、超声时间23min、提取温度43℃,在此条件下可溶性膳食纤维得率达22.92%。

Abstract:

Response surface methodology was applied to optimize the extraction process conditions of soluble dietary
fiber (SDF) from Eucommia seed meal. Three independent variables including material/liquid ratio, ultrasonication time and
temperature were chosen with respect to the dependent variable SDF yield for one-factor-at-a-time design. A mathematical
model was established by Box-Behnken experimental design and analyzed by response surface methodology. The results
showed that the optimal extraction conditions were determined as follows: alkali concentration 2.0 g/100 mL, material/liquid
ratio 1:23 (g/mL), ultrasonication time 23 min, and extraction temperature 43 ℃. Under the optimal extraction conditions,
the yield of SDF was 22.92%.
