Sugar beet arabinan is a hemicellulosic polymer which consists of L-arabino- furanoside. Sugar beet pulp (SBP) is a waste from the sugar industry. In this study, the efficient arabinan extraction process is examined from SBP by using hot water or autoclaving treatments. Before the extraction of sugar beet arabinan, the pellets were 2-3 times repeatedly washed with distilled water to remove the residual sucrose. The autoclaving treatment showed the highest extraction yield. As the longer extraction time, the more arabinan was extracted, while its purity was lowered. Thin layer chromatography analyses revealed that the optimal extraction time for 5% (w/v) SBP was determined as 1 hr and the yield (w/w%) of the arabinan extract was approximately 6%. The purity of arabinan extracted from SBP was 23.7%. After the ethanol precipitation, the purified arabinan was obtained from the supernatant and its purity improved to 66.5%.
