Investigation of the molecular interactions between β-lactoglobulin and low methoxyl pectin by multi-detection High Performance Size Exclusion Chromatography

Weight average molecular characteristics of interacting systems containing βLG (0.3 mg/mL) and LMP (0.1 mg/mL) as studied by HPSEC. Data were analyzed by integrating the chromatographs as peaks 1, 2, 3 and 4. (A) Experimental % Mass Fraction and estimated bound βLG:LMP (w/w); (B) weight average molar mass ([Mw]); and (C) weight average intrinsic viscosity ([ηw]). Error bar represents standard deviation of a set of triple RI measurements.128
