半纤维素为植物纤维物质三大主要成份之一,其含量仅次干纤维素,在甘蔗渣中,半纤维素的含量较高。分析表明,台糖134混合蔗渣中,半纤维素含量占综纤维素的43%,占苯醇抽提后蔗渣的35%。目前,在纸浆,人造纤维等的生产过程中,半纤维素尚未得到合理利用,诸多排放江湖,污染环境,其开发利用是一个值得重视的课题。蔗渣半纤维素的组成及结构蔗渣半纤维素中,存在着多种糖基,主要是D-木糖,其次为L-阿拉伯糖,还有少量的
Hemicellulose is one of the three major components of plant fiber material, its content is only secondary cellulose, in the bagasse, hemicellulose content is higher. The analysis showed that the content of hemicellulose in Taiwan Sugar 134 mixed bagasse accounted for 43% of holocellulose, accounting for 35% of the bagasse after alcohol extraction. At present, hemicellulose has not been properly utilized in the production process of pulp and man-made fiber, etc. Many of them are discharged to the rivers and lakes to pollute the environment. Therefore, the development and utilization of hemicellulose is a topic worthy of attention. Composition and structure of bagasse hemicellulose In bagasse hemicellulose, there are a variety of sugar groups, mainly D-xylose, followed by L-arabinose, and a small amount of
