原始语种摘要: Microcrystalline cellulose (MCC) was isolated from papaya stem, characterized and compared with a commercial brand MCC. The dried pulverized papaya stem was subjected to alkaline treatment using aqueous NaOH and NaOCl solutions. Alpha cellulose obtained was modified by partial hydrolysis using 2.5 M HCl at boiling temperature to produce microcrystalline cellulose. The Physicochemical properties such as bulk, tapped and true densities, degree of polymerization, particle sizes, moisture content, angle of repose etc were examined and compared with a commercial brand sample (C-MCC). Results have shown that the percentage yields of alpha cellulose and CU-MCC obtained from the starting dried stem material were 23.78 and 20.70, respectively. Fourier Transform Infrared (FT-IR) spectra of CU-MCC...
