Abstract
Oil palm (Elaeis guineensis Jacq.) fronds (OPF) are produced worldwide as a by-product of the palm oil industries and represent another abundant raw material in Malaysia. Extraction of hemicellulose from OPF was conducted with two hydrothermal treatments; steam explosion and heating with autoclave. The mixture of OPF chips-water or OPF-KOH (1:10, w/v) were steam exploded at severity of 2.96-3.84 (180-210 ⁰C for 4 min) before extracted with water at 70 ⁰C for 2 h. In the treatment using autoclave, the mixture of OPF-water (1:10, w/v) was autohydrolysed in an autoclave at severity of 1.92-2.52 (121 ⁰C for 20-80 min). Steam explosion at severity of 3.84 (210 ⁰C for 4 min) and severity factor of 2.40 (121 ⁰C for 60 min) produced water-soluble hemicelluloses (WS-STEXw_210, WS-STEXk_210, STAH_60) of 15.75 %, 26.50 % and 24.77 %, respectively.
