摘要:

利用响应面分析法(Response Surface Method)对超声辅助提取杨梅渣水溶性膳食纤维(SDF)工艺进行优化。在单因素实验的基础上,根据中心组合(Box-Benhnken)实验设计原理,采用三因素三水平的响应面分析法,以杨梅渣SDF得率为响应值进行回归分析。结果表明杨梅渣SDF的最佳提取工艺条件为:超声功率为60 W、超声时间为20.5 min、超声温度为71℃时,杨梅渣SDF的提取率为8.4%,与模型预测值基本相符。超声波辅助提取法是一种较好提取杨梅渣膳食纤维的方法。

Ultrasound-assisted extraction (UAE) of water soluble dietary fiber from Bayberry Pomace was studied. The effects of three factors on the yield of water soluble dietary fiber polysaccharides were investigated. Response surface methodology (RSM) was applied to optimize the process of extraction. Box-Benhnken experimental design was used for experimental design and data analysis was conducted to obtain the optimum extraction conditions. Results: The obtained optimum conditions were ultrasonic time 20.5 min, ultrasonic temperature 71˚C and ultrasonic power 60 W. Under the optimized conditions, the extraction yield of water soluble dietary fiber was up to 8.4%, in close agreement with values predicted by the mathematical model. Ultrasound-assisted extraction is a best method for extraction of wa- ter soluble dietary fiber from Bayberry Pomace.
