摘　　要：以本地香蕉皮为原料,采用不同提取剂协同微波法提取果胶,分析果胶的产率及理化性质,结果显示六偏磷酸钠协同微波法来制备皮果胶得率和品质较好。以六偏磷酸钠提取剂协同微波提取香蕉皮果胶,通过单因素试验和正交法优选,确定了香蕉皮果胶提取的最优工艺条件。结果表明:加入0.6%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:料液比为1∶12 g/mL、pH值为2、微波功率为800 W、微波时间为3 min,果胶提取率达10.15%。The pectin was extracted from banana peel by microwave with different extractants.The yield and physicochemical properties of pectin were analyzed.The results showed that the pectin yield and quality of banana sodium hexametaphosphate were better by microwave-assisted extraction.The optimum extraction conditions of pectin from banana peel were determined by single-factor experiment and orthogonal test,using sodium hexametaphosphate extractant and microwave.The results showed that the optimum technological parameters for extracting pectin by microwave-assisted extraction with 0.6% sodium hexametaphosphate chelating agent were as follows:the ratio of material to liquid was 1∶12,the pH value was 2,the microwave power was 800 W,the microwave time was 3 min,the extraction rate of pectin was 10.15%.
