Abstract

Extraction and characterization of microcrystalline cellulose from mango kernel: A waste management approach

Author(s): 1 Nwadiogb J. O., 2 Igwe A. A., 3 Okoye N. H. and 4 Chime C. C.

In this work, the compositional characteristics of mango kernel (MK) were established in terms of lign in, cellulose and hemicelluloses contents, to access its suitabil ity for the extraction of microfibrils. Cellulose a mounting to (25.2 %), hemicelluloses (34.06 %), lignin (15 %) were ex tracted. Microcrystalline cellulose (MCC) was extra cted by hydrochloric acid hydrolysis of α -cellulose derived from the MK. The morphology of t he MK-MCC was investigated using scanning electron microscope (SEM), and showe d a compact structure and rough surface. X-ray diff raction (XRD) analysis showed that the MCC produced is of c ellulose-1 polymorph, with 50.3% crystallinity. The physicochemical properties of the MCC suggests that the cellulose has good flow and compression proper ties, hence suitable for a range of applications such as green biodegradable nanocomposites reinforced with this f orm of cellulose and pharmaceutical tabletting.
