Characteristics of crude cellulose from palm (Elaeis oleifera) midrib by sodium hydroxide pretreatment
Journal Title: Food Research - Year 2018, Vol 2, Issue 3
Abstract
The purpose of this research was to determine the effect of concentration of sodium hydroxide (NaOH) on physicochemical characteristics of cellulose powder extracted from palm midrib that was underutilized optimally. Cellulose extraction was done using a solution of NaOH with concentrations of 9, 12, 15, 18%. Cellulose powder obtained was analyzed water content, cellulose content, yield, lightness, functional groups, and crystallinity. Cellulose powder extracted with NaOH 15% had water content 9.3% (w.b), cellulose content 89.63% (d.b), yield 37.32% (d.b), lightness value 90.83, and crystallinity 31.57%. NaOH had the ability to break lignocellulose bond so that cellulose will be free from lignin. The results of FTIR spectra analysis of commercial cellulose and cellulose from palm midrib extracted with NaOH 15% solution showed the same pattern of the functional group.
