Abstract
Cassava bagasse is one of the abounding garbage procured from the extraction of cassava. Extraction of products of high value from agricultural wastes is a crucial constituent for sustainable techno economic development. In this study, extraction and characterisation of wax from cassava bagasse was carried out. About 9.86% (w/w) of crude cassava wax was obtained from the cassava bagasse using the mixture of benzene and methanol (mass ratio of 2:1) as the extraction reagents. The wax extracted was characterised using fourier transform infra-red spectroscopy (FTIR), ultraviolet visible spectroscopy (UV-Vis) and scanning electron microscopy (SEM). The physicochemical properties were studied: melting point, saponification value, acid value, ester value and iodine value. Results of fourier transform infra-red spectroscopy revealed prominent peaks at 2911 cm-1 (CH), 1464 cm-1(CH2), 1028 cm- 1(-C-O), 1717 cm-1(-CHO) and 3382 cm-1 (OH) illustrating the presence of alkanes, ketones, aldehyde and alcohol, respectively. The ultraviolet qualitative analysis displayed the existence of conjugated dienes at 245 nm. The dewaxed sample showed a rough, cracked and individualised surface indicating the removal of wax. In addition, the physicochemical properties of the wax which comprises of melting point, saponification value, acid value, ester value and iodine value were 62.5oC, 275, 29.15, 245.85,14.66 and 22.54 mg/KOH/g, respectively. Thus, cassava bagasse wax has relevance for various industrial applications in food, pharmaceutical, cosmetics, medicine and several biological importance.
