Small granular starches from rice, quinoa and amaranth were modified with octenyl succinic anhydride (OSA) at 5 defined intervals (0 to 3.0%) and investigated with respect to emulsifying capacity and stability. Starch granules’ surface were characterized by Brunauer–Emmett–Teller and contact angle measurements. Emulsifying capacity was characterized by multiple light scattering (MLS) and particle size analysis. Stability towards environmental stress was characterized by centrifugation and...
