Study of hemicellulose B recovery yield from rice bran
Abstract
Hemicelluloses, one of the most abundant natural polysaccharides, are comprised roughly in one-fourth to one-third of most plant materials. Hemicelluloses contain mixtures of 50-200 five-carbon sugars(xylose and arabinose) and six-carbon sugars(glucose, galactose, mannose, and rhamnose), plus lesser amounts of the sugar acids(glucuronic acid and galacturonic acid). The kinds of hemicelluloses are A, B, and C. The interesting substance of them is hemicellulose B. However, the prodution level of hemicellulose B is very low. Thus, this study was concentrated on increasing the recovery yield of hemicellulose B from rice bran.
본 연구는 고수율의 아라비녹실란을 얻기 위해 필수요소인 hemicellulose B의 회수율을 검토하였다. 검토결과 10% acetic solution으로 pH 4.2로 적정 후 반응시키는 단계에서의 온도를
