效应面法优选小儿消食化积膏的提取工艺

Optimal Extraction of Xiaoshihuaji Jelly by Response Surface Methodology

优选小儿消食化积膏的提取工艺。以加水量和煎煮时间为主要影响因素,以枸橼酸含量和干膏率为评价指标,用星点设计-效应面法优选小儿消食化积膏的提取工艺。最佳工艺条件为加入17倍量的水,煎煮155 min,煎煮2次。该工艺合理可行,稳定可靠。

The best extraction of Xiaoshihuaji jelly for children was optimized. The main influential factors of extraction technology included the quantity of water and extraction times. The extraction effect was evaluated with the content of citric acid and the extract yield. The optimal extraction technology of Xiaoshihuaji jelly for children was selected by Central Composite Design-Response Surface Methodology. The best extraction conditions as follows： 17-fold of water,extracted for twice and 155 minuties each time. The optimized extraction technology was simple, convenient, stable and feasible.
