Morphology-regulated millet bran nanocellulose-zein nanoparticles complexes: stabilization of Pickering emulsions and β-carotene delivery.

ABSTRACT: This study revealed how the morphology of millet bran nanocelluloses, including cellulose nanocrystals (MCNCs), cellulose nanofibrils (MCNFs), and cellulose nanospheres (MCNSs), regulated the complexation with zein nanoparticles (ZNPs), thereby influencing structure and emulsifying performance of the resulting complexes. Electrostatic attraction, hydrogen bonding, and hydrophobic interaction induced 'chain-bead-like' structures in MCNCs-ZNPs and MCNFs-ZNPs, while MCNSs-ZNPs exhibited a 'bead-bead-like' structure. The 'chain-bead-like' structures conferred better emulsifying ability, producing emulsions with smaller droplets, higher viscosity, and better stability due to dense continuous phase networks, while 'bead-bead-like' structure induced a looser network. Structural advantages also pe
