Abstract
This study was carried out to find the optimal isolation conditions of xylan from steam-exploded materials, such as rice straw(Oryza sativa), barley straw(Hordeum vulgare) and oak wood(Quercus mongolica), In the chemical composition, we found that the contents of water-extractives and ash of rice straw and barley straw were more than those of oak wood. Rice straw, barley straw and oak wood were steam-exploded at 20kgf/
본 연구는 농산 및 임산폐자원을 폭쇄처리한 후 xylan을 단리하기 위한 최적의 방법과 조건을 확립하기 위해 수행하였다. 농산 및 임산폐자원으로는 볏짚, 보릿짚 및 신갈나무를 시료로 하였다. 농산 및 임산폐자원의 화학 조성을 살펴보면, 볏짚 및 보릿짚에서의 추출물 함량과 무기물 함량은 신갈나무보다 약 10~20% 정도 높게 나타났다. 폭쇄전처리는 20kgf/
