Abstract

Abstract : Citrus fruit processing industries produce a vast quantity of waste materials as peel and pulp that are not handled properly. In present study, waste generated from citrus has been used for extraction of cellulose and nanocellulose. The aggregated cellulose, derived after alkaline treatment, was acid hydrolysed; resulted in reduction of the size of cellulose fibre. The cellulose showed amorphous structure revealed by X‐ray diffraction analysis. Scanning electron microscopy analysis explained densely packed structure of nanocellulose. High magnification revealed break points in cellulose fibre due to acidic treatment; looked like carbon nanotubes. The simple solubility test demonstrated that different solvents had different effects on the dissolution of nanocellulose. The study reveals that citrus peel is also a good candidate of cellulose that can be utilised for different applications.
