Cellulose Extraction from Cyperus Corymbosus Rottb L. for Dietary Fiber

Abstract

The aims of this research were to study the cellulose extraction methods of Cyperus Corymbosus Rottb L. in saline soil and general soil and study the chemical compositions of Cyperus Corymbosus Rottb L. for the potential application in the food industry and finding alternative sources of cellulose.  In the present-day, Thailand has introduced many kinds of plants to extract the cellulose, but still need to import from abroad due to insufficient quantity.  The Cyperus Corymbosus Rottb L. is one alternative plants to use because it inexpensive and salty weed.  

The Cyperus Corymbosus Rottb L. in saline soil and general soil were observed the moisture at 2.04% and 2.67%, ash at 2.64%, 2.32%, alpha-cellulose at 43.73%, 51.61%, Holocellulose at 97.02%, 70.52% and lignin at 14.92%, 17.30%, respectively.  The extraction recoveries of cellulose for Cyperus Corymbosus Rottb L. in saline soil and general soil were 81.91% and 88.74%, respectively.  The cellulose structure was characterized by Fourier-transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD).  According to the studies, it has been found that Cyperus Corymbosus Rottb L. in saline soil and general soil revealed the high fiber content indicating that the Cyperus Corymbosus Rottb L. in saline soil and general soil can be used to the raw material dietary fiber, which is the low energy.
