摘要
以石榴皮为原料利用酶或螯合剂协同微波法提取果胶,分析果胶的提取率及理化性质,发现六偏磷酸钠协同微波法制备石榴皮果胶提取率和品质较好。以六偏磷酸钠为萃取剂,采用微波提取石榴皮果胶,通过单因素试验和正交法优选,确定了石榴皮果胶提取的最优工艺条件。结果表明,加入0.2%含量的六偏磷酸钠螯合剂辅助微波法提取果胶的最佳工艺参数为料液比1∶15,pH值1.5,微波功率600 W,微波时间3 min,果胶提取率达7.75%。
The extraction process for pectin from loquat peel using sodium hexametaphosphate as the extraction solvent combined with microwave-assisted,was optimized by single factor experiment and orthogonal experiment,and then the pectin quality was analyzed.With addition of 0.2%sodium hexametaphosphate,the optimum conditions were as follows:solid-liquid ratio of 1∶15(g∶mL),pH value 1.5,microwave power mid-range 600 W,and microwave radiation time 3 min.Under these conditions,the extraction yield of pection was 7.75%.
