In the present study low cost microcrystalline cellulose (MCC) powder was prepared from cornhusk ï¬bres, extracted chemically followed by anaerobic consortium treatment. Cornhusk ï¬bres were treated with 10% alkali at 120 for 60 min followed by anaerobic consortium treatment for 3 days. It was then bleached with hydrogen peroxide and ï¬nally washed. Bleached pulp was hydrolysed using 4 N HCl to get the MCC. In the present investigation, we have characterized the MCC prepared from cornhusk ï¬bres thoroughly for its physico-chemical properties and compared with Avicel-PH 101, a commercial grade MCC. Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Powder Diffraction (XRD) and Differential Scanning Calorimetry (DSC) were used for characterization of samples. Similarly the powder and ï¬‚ow properties of the MCC prepared from cornhusk ï¬bres were also investigated and the results were compared with Avicel-PH 101. Our results showed that various properties and the purity of MCC prepared from Cornhusk ï¬bres are comparable to the commercial grade MCC. Since, cornhusk is an agricultural waste product, MCC obtained from cornhusk ï¬bres will be from cheaper raw materials than current market MCC.
