摘要
为研究山楂果胶有效提取工艺方法,以干燥的山楂果粉为原料,采用传统的酸法(直接加热法)和微波辐射法提取果胶,通过单因素试验和正交试验确定果胶提取的最佳工艺参数。结果表明:山楂果胶提取的最佳工艺为微波辐射提取,功率700W,料液比为1∶30,提取液pH 2.0,提取时间为120s,果胶提取率为5.7%。与传统的酸法直接加热提取相比,微波提取果胶提取率增加了1.0%,提取时间也缩短为传统酸法提取的1/40倍。
For the study of pectin extraction process effectively, taking dry hawthorn(crataegus pinaatifida)pow- der as raw material, pectin was extracted by the traditional method of acid direct heating and microwave radia- tion,and the optimum technologic parameters of pectin extraction were identified by single-factor experiments and orthogonal tests. The results showed that the optimum technology of hawthorn pectin extraction was as follow:microwave radiation was used with power of 700 W, the ratio of material to liquid was 1:30, pH was 2.0, extraction time was 120 s,and the pectin yield was 5.7 %. Compared with the traditional extraction method of acid direct heating,microwave pectin extraction yield increased by 1.0%, extraction time was reduced 1/40 of the traditional method.
