Associative phase separation involving canola protein isolate with both sulphated and carboxylated polysaccharides

► Optimal canola protein-alginate or ι-carrageenan interactions occurs at a 20:1 mixing ratio. ► Coacervation is formed through electrostatic attraction with secondary stabilisation by hydrogen bonding. ► Solubility is canola protein-alginate mixtures are enhanced relative to canola alone.
