The modification of extractant type on the structure and morphology of sugar beet pectin was studied in this study. Sugar beet pectin showed a compact texture and the appearance was made up of irregularly folding architecture. After treatment with the oxalate ammonia(80 ℃, pH 5.2, twice), the calcium content in the sugar beet pulp decreased from 1.28% to 0.81%; the morphology of the sugar beet pulp changed into a highly loose and polyporous texture., while the major functional groups and the crystallinity o...
