abstract = {<p style="text-align: justify;">The pomelo peel, a by-product of pomelo processing, is predominantly discarded. To fully exploit
the pomelo peel resources and contribute to environmental improvement and resource recycling, this
study reports a green method for extracting cellulose nanofibrils (CNFs) from pomelo peel through
hydrothermal-assisted alkali treatment. Lemon juice is employed for further ball milling treatment to
purify the CNFs. The chemical structure, crystallinity, thermal stability, and microstructure of pomelo
peel powder and CNFs are analyzed. The study results demonstrate that the combination of alkali
treatment, hydrothermal processing, bleaching, and ball milling progressively eliminates hemicellulose,
lignin, and other impurities from the pomelo peel, yielding high-quality CNFs. The CNFs retain the
natural cellulose structure, with enhanced thermal stability and crystallinity. The diameters of the CNFs
range from 2-30 nm. This method employs lower NaOH concentrations than previous studies, resulting
in CNFs with higher crystallinity and smaller diameters. This study provides a promising method for
enhancing the value-added of pomelo peel and increasing the volume of CNF production.</p>},
