Enhancing Fucoxanthin Pickering Emulsion Stability and Encapsulation with Seaweed Cellulose Nanofibrils Using High-Pressure Homogenization.

ABSTRACT: Poor solubility and bioavailability have limited the application of fucoxanthin in drug and functional food processing. In order to encapsulate fucoxanthin in delivery systems, in this study, cellulose was isolated from industrial brown algae residues and high-pressure homogenized into cellulose nanofibrils (CNFs). Then, fucoxanthin was encapsulated into the Pickering emulsion stabilized by the CNFs. The effect of high-pressure homogenization on the characteristics of cellulose and the stability of fucoxanthin emulsion was evaluated. The results indicated that CNFs prepared at 105 MPa had a diameter of 87 nm and exhibited high zeta potential and thermal stability. Encapsulation efficiency peaked at 70.8% with 1.0 mg/mL fucoxanthin, and after three freeze-thaw cycles the encapsulation effic
