Sedimentation coefficient distribution diagrams of gliadins and iota carrageenan in aqueous phosphate-chloride buffer. c(s) = the population of species with a sedimentation coefficient between s and ds. UV-absorption optics at 280 nm were used showing only the gliadins – and whatever they may have interacted with. Red line: gliadin only control at 5.0 mg/ml loading concentration showing material sedimenting at 2 S and a small amount of aggregated material at ~ 5 S. Blue line i- carrageenan control at 1.0 mg/ml: the sedimenting material is almost transparent at 280 nm. Black line (same concentrations) – mixture showing a substantial amount of material sedimenting at ~ 4.5 S: this may indicate an interaction with gliadin.
