Protein-polysaccharide complex carrier can solve the problem of insufficient stability of Monascus pigments (MPs), a kind of natural pigments, against heat and light. It also has the function to stabilize Pickering emulsion (PE) that can be used as fat replacer in meat products. In this study, heat denatured whey protein (HWP) and pectin modified by octenyl succinic anhydride (OSA-pectin) were prepared into complex by adding Ca
