AbstractNanoresistant particles based on chemically modified starch (RS IV) are prepared through a high‐speed shearing emulsification method, and the effects of shear speed, shear time, oil/water ratio, and surfactant amount on the particle size are evaluated in this study. The as‐prepared RS IV nanoparticles yield ≈300nm narrow peak with notches and grooves on the surface. In vitro digestibility results suggest that these nanoparticles exhibit high resistance in the stomach, small intestine, and colon contents of mice. A raman assay confirm...
