响应面法提取臭黄荆叶果胶的研究

Study on Opitimization of Extraction Conditions from Premna Hainanensia by Response Surface Methodology

以湖北丹江口移栽至北京农业职业学院的臭黄荆为原料,研究果胶的提取条件和性质。通过单因素试验研究了臭黄荆果胶的最佳提取工艺条件,进一步采用响应面优化法提取臭黄荆果胶。得出果胶最优提取工艺参数为:提取温度69.92℃,提取时间为1.53 h,pH值为1.89,在此条件下的果胶含量为149.68±2.49 mg/g。

In order to study the indexes of pectin in Premna hainanensia transplanted from Danjiangkou of Hubei Province to Bei‐jing Vocational College of Agriculture.This paper studied optimum extraction conditions of Premna Hainanensia pectin through sin‐gle factor test,response surface optimization was further used to extract Premna Hainanensia pectin.The optimal conditions of vari‐ables:extraction temperature is 69.92℃,extraction time is 1.53 h,pH is 1.89,pectin content is 149.68±2.49 mg/g.
