摘要
采用水热法进行菊芋中菊糖的提取,通过设计单因素实验,确定了影响菊糖提取温度、时间和磷酸浓度3个主要影响因素。使用响应面法对菊糖提取工艺进行最优分析,利用Design-Expert软件设计3因素3水平实验,得出菊糖的最佳提取工艺条件为:水浴温度87℃,提取时间82 min,磷酸浓度0.7 g/L,在此条件下,菊糖的提取率达到了22.44%。经实验验证,结果与预测值相符,证明预测模型有效,可以用于菊糖提取工艺的优化。为高原地区进一步开发利用菊芋提供理论依据和数据支撑。
The extraction of inulin from Jerusalem artichoke was carried out by hydrothermal method.Through designing single factor experiment,three main factors affecting the extraction temperature,time and phosphoric acid concentration were determined.Using response surface method for optimal analysis of the extraction process of inulin,using the Design-Expert software to design three factors and three levels of experiments,obtained the best extraction conditions of inulin:water bath temperature 87℃,extraction time 82 min,phosphate concentration 0.7 g/L,under this condition,the extraction rate of inulin reached 22.44%.The results are consistent with the predicted values,which proves that the prediction model is effective and can be used to optimize the extraction process of inulin.This study provides theoretical basis and data support for the further development and utilization of Jerusalem artichoke in plateau area.
