Direct measurements of interfacial interactions between pectin and kappa-casein and implications for the stabilisation of calcium-free casein micelle mimics.

Abstract

Using Surface Plasmon Resonance (SPR) it has been shown that the fine structure of the anionic polysaccharide pectin strongly influences its interfacial interaction with a kappa-casein layer coated onto a gold surface (via a dextran linker) in the pH range 3.5-6.8, with the highest SPR signal being observed for pectin with the lowest charge density tested… (More)
