Affinisol® (Hydroxypropylmethyl cellulose) polymers with low glass-transition temperature are usually processed by Melt Extrusion and show better compressibility at lower compression pressure. This study evaluates the compaction properties and powder properties of Affinisol® Powder by the determination of physical properties like bulk/tapped density, angle of repose and loss on drying, an out-of-die compactability, axial expansion post-compression, effect of compression force on hardness of...

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...
