| Abstract: | For improving the utilization of resources,the optimal extraction conditions of pectin from Edible Canna residue had been extracted starch.And a qualitative analysis of pectin was carried out.The optimal extraction conditions of acid hydrolysis were gained by single experiments and orthogonal test in which pH was 4.0,extracted temperature was 80 ℃,extracted time was 1.5 h,and solid-liquid ratio was 1∶20.Under the optimal extraction conditions,the yield of pectin was about 7.72%. |
