Molecular migration of konjac glucomannan and gum Arabic phase separation and its application in oil-water interfaces

Molecular migration of gum Arabic (GA) fragments was investigated, when thermodynamic phase separation occurred in mixtures of konjac glucomannan (KGM) and GA at different concentrations. It has been quantitatively analyzed by GPC-MALLS. After reaching phase equilibrium, GA with the small molecular weight migrated into KGM-rich phase, resulting in a decrease of its relative content (from 13.58% to 0.05%) in GA-rich phase. GA was dyed with...
