Molecular Fractionation Induced by Viscosity-Driven Segregative Phase Separation Behavior of Gum ArabicHydroxypropyl Methylcellulose

Segregative phase separation technology demonstrates substantial potential for precise molecular fractionation in food and biomaterial applications. The investigation elucidates the causal relationship between viscosity variations and phase separation dynamics, which govern molecular fractionation in GA/HPMC composite systems. By conducting a compar- ative analysis of two GA subtypes (CGA and SGA) and three HPMC grades with controlled viscosity gradients, we utilized gel permeation...
