Abstract Cellulose nanocrystals (CNC) are rod-shaped, nanoscale colloidal particles. Their strong hydrophilicity and the single functional group structure seriously have limited potential utilization in stabilizing Pickering emulsions. This study aimed to improve the emulsification ability of CNC to prepare more stable emulsions. CNC and gelatin protein (GE) were combined to form complex colloidal particles, and subsequently stabilizing oil phase to fabricate stable O/W Pickering emulsions. The effects of different pH and compound ratios on the properties of CNC/GE complexes were characterized and analyzed using Zeta potential, turbidity, and Fourier transform infrared spectroscopy (FTIR). The characteristics of the obtained Pickering emulsions were investigated by morphology observation, particle size and distribution experiments. The results indicated that the CNC/GE complex colloidal particles were formed by electrostatic interaction at pH4.2, which presented excellent emulsification performance and thermal stabili
