响应面法优化香蕉叶可溶性糖提取工艺

Optimization of the Extraction Process of Soluble Sugar From Banana Leaves With Response Surface Methodology

为了优化香蕉叶中可溶性糖的提取工艺,采用单因素实验考察浸提温度、浸提时间、液料比值对香蕉叶可溶性糖提取的影响,并根据单因素实验结果利用响应面法对香蕉叶可溶性糖提取工艺进行了3因素3水平的优化。结果表明:液料比值对提取量的影响最大,浸提温度次之,而浸提时间影响最小。通过响应面优化得到的最优工艺条件为:浸提温度85℃,浸提时间100 min,液料比值60 mL·g-1。

In order to optimize the extraction process of soluble sugar in banana leaves,a single factor experiment was used to investigate the effect of extraction temperature,extraction time,liquid-to-material ratio on the extraction of soluble sugar in banana leaves,and the response surface method was used to optimize the extraction process of soluble sugar in banana leaves based on the single factor experiment results.The results showed that the liquid-material ratio had the largest influence on the extraction volume,followed by the extraction temperature,and the extraction time had the smallest effect.The optimal process conditions obtained through response surface optimization were as follows:leaching temperature 85℃,leaching time 100 min,liquid-to-material ratio 60 mL·g-1.
