　　Intact starch granules are a new source of particles for stabilizing food-grade Pickering emulsions.The size of the starch particulates was reduced by ethanol precipitation,and then starch nanoparticles are modified by octenyl succinic anhydride(OSA)to obtain surface activity.These pH-responsive amphiphilic starch-based nanoparticles(APS NPs)of 100-500 nm were selected to prepare o/w Pickering emulsions because of their good stability against coalescence.By Fluorescence Microscopy,it was observed that APS NPs were closely packed and distributed at the surface of the emulsion droplets.
