To increase the added value of pomegranate peel, pomegranate peel nanocellulose was prepared by alkali treatment and sodium hypochlorite bleaching, and pomegranate peel cellulose nanocrystals (PCNC) was successfully prepared by acid hydrolysis. The particle size and stability of PCNC were characterized, and the pomegranate pomace and PCNC were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). Results showed that the particle size of PCNC was 201 nm, the Zeta potential value was -38.6 mV, PCNC had nano-size, and the suspension of PCNC had good stability. The microstructure analysis showed that PCNC had high crystallinity and rod-like structure. The crystallinity of pomegranate peel and PCNC measured by XRD was 33% and 63%, respectively. FITR showed that hemicellulose and lignin in pomegranate peel residue were successfully removed. The thermal stability analysis showed that the thermal stability of PCNC was slightly lower than that of pomegranate pomace.
