Phase segregation of amylopectin and beta-lactoglobulin in aqueous system
(2008) In Carbohydrate Polymers 72(1). p.151-159- Abstract
- Phase behavior of aqueous amylopectin and beta-lactoglobulin system was studied using Fourier transform infrared spectroscopy. Polysaccharide-protein mixtures were prepared at different concentrations and left for equilibration; afterwards their spectra were recorded and correlated using Partial Least Square analysis. Tertiary phase diagrams were built for the system at different equilibration times (2 and 6 weeks); the binodals were asymmetric and displayed toward the protein concentration. In the two-phase region of the phase diagrams the mixtures showed an upper layer rich in beta-lactoglobulin and a lower layer rich in retrograded amylopectin, and in some cases an intermediate layer was seen which was a metastable phase.
