Characterization and In Vitro digestibility of rice protein prepared by enzyme-assisted microfluidization: Comparison to alkaline extraction

► Microfluidization followed by density-based separation extracts rice protein. ► Carbohydrate-hydrolyzing enzyme treatments improve protein purity. ► Rice glutelin with native structure is non-destructively and selectively obtained. ► Rice glutelin shows better in vitro digestibility than alkali-prepared protein.
