Abstract
Extraction of products of high value from agricultural wastes is an essential component for sustainable techno economic development. In this study, extraction of wax from cassava and sugarcane bagasse was carried out using a mixture of benzene and methanol (mass ratio of 2:1) as the extraction reagent. About 9.86% (w/w) of crude cassava wax and 4.10% (w/w) of sugarcane bagasse wax. The physicochemical properties and characterization was compared for both waxes. Results of fourier transform-infrared spectroscopy showed prominent peaks at CH, CH2, C-O and OH indicating the presence of alkanes, carbonyls and alcohol respectively for both waxes. Ultraviolet qualitative analysis revealed that the waxes absorbed UV light at 245 nm and 215 nm for cassava and sugarcane bagasse wax, respectively, indicating the presence of conjugated dienes. In addition, the physicochemical properties of the cassava and sugarcane bagasse wax evaluated were; melting point (62.5oC and 76oC), saponification value (275 mg/KOH/g and 202.6 mg/KOH/g), acid value (29.15mg/KOH and 6.7 mg/KOH/g), ester value (245.85 and 180.06), free fatty acid (14.66 mg/KOH/g and 3.45 mg/KOH/g) and iodine value ( 22.54 mg/KOH/g), respectively. Thus, cassava and sugarcane bagasse wax have potential for various applications in the industry such as food preservative, medicinal and has several biological and industrial importance.
