Abstract

Hemicellulose, as one of the key components of the plant cell wall, is the second most abundant plant polysaccharide in nature, after cellulose. It is highly valued by both the academic and industrial communities because of its low cost, environmental friendliness, renewability, and biodegradability. In this review, we provide a comprehensive elaboration of the mechanisms and the latest research advancements in hemicellulose extraction using various methods, including alkali extraction, hydrothermal pretreatment, acid extraction, and deep eutectic solvent extraction. Furthermore, applications of hemicellulose-based hydrogels as adsorbent, drug delivery materials, wound dressings, bone tissue engineering materials, and flexible sensors are presented. The four most commonly used types of hemicellulose polysaccharides regarding wound healing, including xyloglucan, xylan, konjac glucomannan, and seed-derived galactomannan, are systematically addressed. At last, perspectives on current challenges and future development trends of hemicellulose are briefly presented. The purpose of this review is to provide actionable strategies for biomass valorization.

半纤维素的提取及其作为水凝胶的应用综述

半纤维素是植物细胞壁的关键成分之一，是自然界中含量第二丰富的植物多糖，仅次于纤维素。它具有成本低、环境友好、可再生、可生物降解等特点，受到学术界和工业界的高度重视。本文综述了半纤维素提取的机理，并对碱萃取、水热预处理、酸萃取和深共晶溶剂萃取等半纤维素提取方法的最新研究进展进行了综述。此外，介绍了半纤维素基水凝胶在吸附剂、药物递送材料、伤口敷料、骨组织工程材料和柔性传感器等方面的应用。关于伤口愈合的四种最常用的半纤维素多糖类型，包括木葡聚糖，木聚糖，魔芋葡甘露聚糖和种子衍生的半乳甘露聚糖，被系统地处理。最后，对半纤维素目前面临的挑战和未来的发展趋势进行了简要的展望。本文综述的目的是为生物质增值提供可行的策略。
