首先用有机酸水溶液法从罗望子种子中提取罗望子果胶，然后以正交优化的方法对其相关工艺进行了优化，最后对罗望子果胶的抗氧化能力进行了研究。研究表明：最佳提取工艺如下：料液比1：35， pH＝4.6，煮沸20 min，沉降4 h；通过实验证明：在此条件下，果胶提取率可达到52.8％。通过最佳工艺所得产品指标优于国家果胶产品标准；最后通过对罗望子果胶清除DPPH＆#183;自由基能力和总抗氧化能力的测定，得到了其具有一定的抗氧化性的结论。

The extracting technology of tamarind gum from the seed of tamarind gum was mainly studied.The single factor analysis and orthogonal test were designed to confirm the main factors and the optimum conditions .The results showed that the optimum conditions were pH =4.6, extraction time 20 min, solid:liquid ratio 1:35(w:V), and sedimentation time 4 h.Under these conditions , the extraction rate of pectin was 52.8%.The results showed that each performance index of the product was better than that of the national criterion.In addition, the DPPH and FRAP methods were used to measure the antioxidant ...
