摘　　要：为充分利用辣椒红素加工中废弃的副产物,采用微波辅助技术从中提取用途广泛、附加值高的果胶物质。在单因素实验基础上,通过正交实验优化提取工艺参数,确定了最佳提取条件为:所用酸为硫酸,微波功率为中低频,微波时间5min,料液比1∶20,p H为1,此时果胶提取率可达57.9%,并确定为高甲氧基果胶。Microware-associated extraction was used to extract pectin from capsanthin by-products. The optimal extraction technology was obtained by the single factor test and the orthogonal tests. The optimal extraction conditions were ：extraction acid reagent was H2SO4,the microware power was lower to middle and extraction time was 5min,the ratio of solid to liquid was 1 ：20 and p H was 1. The result showed the extraction rate reached 57.9%. And this pectin was confirmed as high-methyl pectin.
