Alginate-based colloid particles from direct chemical self-assembly using as particulate emulsifiers
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.
