A new kind of dopamine modified alginate colloid particles (DA-ALG CPs) was prepared via the direct chemical self-assembly triggered by the amidation reaction between dopamine and alginate in aqueous solution. The structure and morphology of the DA-ALG CPs were characterized by infrared spectroscopy, Zeta PALS and scanning electron microscope. The prepared DA-ALG CPs were then used as particulate emulsifier to prepare Pickering emulsions. The properties of the emulsion were characterized by optical microscope. The results revealed that the prepared DA-ALG CPs exhibited good emulsifying property at a wide pH value range, which will endow the potential application of the Pickering emulsions stabilized by DA-ALG CPs in food and biological medicine fields.
